Hence, the main height of the frame is as follows : I — 2 inches. 2=6 " 4 = 5 i6y^ inches main height. THE PERFORATED BOARD. The perforated bottom board, through which the neck-cords are passed, contains one hole for every hook in the machine, and is illustrated in Fig. II. separately. It shows the following measurements : Entire width of board = 8 inches, length " = 12 Thickness " = ^ TA- ri 1 r u . f in length of board, 0.27 inch.

" " '* " rear part of the frame, 2'^ inches. This board is fastened by screws to the frame at places indicated in Fig. I. by II and 12. THE PLUNGER. Besides the frame, Fig. I. illus- trates: Under I. the Jacquard plunger, ^ inch diameter, for guiding the griffe (attached to its head) when raising. To strengthen the steadiness of this latter movement shoulders are attached to the frame at the three places where the plunger slides. Height of frame at = 2^ inches. /, = 2 Screws, f, dotted in drawing, on head of plunger, fasten the griffe to it. Part III. in Fig. I. illustrates the attachment for providing the lifting of the plunger in a hand-loom, likewise the griffe, etc. This consists of a triangular shaped frame i4/4^ inches high, or less, according to height of room. This part is fastened to the front part of the frame by bolts at 0 and In the slot at the top, between r and s, a wooden cylinder of inches diameter is fastened to an iron shaft resting in the frame at t. At 13 a leather strap is fastened to this cylinder and to the plunger 14. It will easily be seen that by turning the wooden cylinder in the direction of the arrows, 15, the plunger will be raised with the griffe fastened to its top. By 13 reversing the action of the cylinder, the plunger and griffe will return to their previous positions. The action thus described constitutes a "single lift," rai-'^ing and lowering of plunger and griffe for each pick. THE CATCHES. At IV., Fig. I., the " catches " for turning the cylinder at the lantern are illus- trated. The distance of the centre of the screws which hold the catches to the frame is 4.% inches. Between these two catches the cylinder is adjusted to the batten, and the direction of its turning is regulated by the catch which is brought in contact with the lantern. If the catch, y, turns, the cylinder will turn the card situated on its top towards the needle-board, and if catch, 2, is broup-ht into contact with the lantern, the card hanging below the needle- board will be the next in turn to be pushed towards the needles. The entire length of the catches in the present illustra- tion is 8 ins., allowing 51^ ins. for the catch itself and 2^ ins. for the part to which it is fastened. Making this catch in two pieces is preferable to the old style of one piece, because the moment of turning the cylinder can be more easily regulated. THE GRIFFE. Fig. III. illustrates the top view of the griffe. As ^ mentioned before, the griffe is fastened to the plunger ,| ,| ,| s| 6^ ,| by means of screws. In the drawing the dark shaded t places marked / are the hollow places in the griffe, fig. iv. through which the screws fasten the latter to the plunger. The griffe, like the other parts explained, is made of cast iron, and the machine is of the fol- lowing dimensions : Length of griffe, a to d, = 9^ inches. Depth " " ^ to ^, = 65^ Extension on each side, e to /, = 1^2 " Distance of griffe-bars, s to i", = J4 '* Length " " m to n, = 9% Heio-ht Fig. V.

Height of rester, d to c, = 65/^ inches. 14 THE NEEDLE. Fig. VI. illustrates a needle, as used in connection with the hook. Distance from head to loop, gy^ inches, = ^ to Length of loop, I 5^ inches, =c to d. lo^ * inches entire length. fig. vi. The distance from head to eye (for passing through the hook) is regulated according to the row in which the needle belongs. In the present illustration this is, Head to eye, = 7 inches, =a to d. The eye, = ^ inch, = d. Eight different positions of the distance of the eye from head will be required by an 8-row machine. The needles are made of No. 15^ bright spring wire. The loop on the end, c to d, permits a pin to be inserted, [see Fig. VII., o'], and also holds the needle in position. Fig. VII. gives a clear understanding of the arrangement of hooks, needles, griffe-bars, springs, frame for holding the latter, and the needle board. This draw- ing is in accordance with the preceding ones, executed one-fourth of the actual size, and represents the sectional cut of one cross-row in the Jacquard machine contain- ing 8 hooks, (as it is an 8-row deep machine which we explain) : ^ to ist hook. ; y'to /', 2d hook ; to 3d hook ; /i to /i\ 4th hook; i to t', 5th hook; k to k', 6th hook ; / to 7th hook ; m to m\ 8th hook. These hooks are held in their required places by the eyes of the needles [see place v at hook i], through which the former are passed. The needles rest with their heads in the needle-board, a to b, extending out- side, towards the cylinder, for about inch. The rear part of the needle — the loop — is passed between two bars of the spring frame, n, p, and held by the latter firmly, but with sufficient play for a longitudinal motion for pressing towards their springs. The pin, 0, is inserted for holding the springs in their places. One ^' t pin is required for each vertical row of Fig. VII. needles. The part of the spring frame, r, n, p, s, unshaded, is made of cast iron ; the shaded part (extension) is constructed of wood. Below the upper crook of the hooks, the black sections represent a sec- tional cut of the griffe-bars ; v to zv indicates the rester for the lower hooks, which keeps the latter in their required position. A study of this illustration will show that when the heads of the needles, a-b, 15 are pushed backwards, in the direction of arrows, the hooks are also moved. If the needles are not pushed, the upper crooks of the hooks will remain in position, as in drawing, over the griffe-bar; and raising the latter will consequently raise every- one of these hooks. Therefore, if a blank card is pressed against the 208 needles of the machine, all the needles and hooks will be pushed back, out of the way of contact with the griffe-bars, thus causing an empty lift when they are raised ; whereas, by pressing with an empty cylinder, or with a card, containing as many holes as the machine has needles, and so placed that the holes are exactly opposite the needles, none of them would be moved, and each hook would remain vertical over its griffe-bar ; and raising the griffe will lift every hook. As mentioned before, the springs, u, are attached to the needles between the needle-frame, n-p, and the pin, o. Fig. VI., the distance ^ to / indicates the part of the loop around which the spring is adjusted, and where it rests against the expansion of the loop, f, in Fig. VI., represents the place where pin, 0, (as shown in Fig. VII.) passes through the loop and is fastened to the needle-frame on top and bottom. Pressing the needle at the head compresses the spring, as the latter is securely fastened on one end by the wider part of the loop, and on the other end by a pin inserted in the loop and fastened to the frame. Remove the pressure at the head of the needle, and the spring will return to its natural position, pushing the needle into its old place. These springs are made of thin brass wire. It is necessary to keep the needle-eyes in the proper place, otherwise it would result in bending the hook out of its perpendicular position, and by lowering the griffe its bars would possibly come in contact with the head of the hook, crushing the latter, or doing more damage if not detected at once. Each needle or hook, if worn out, can be replaced by pulling out the pin, c, thus loosening the needle and giving a chance to work the required hook out of the needle-eye. THE BATTEN MOTION. Fig. VIII. represents the batten motion to be attached to the guiding- rod, [see No. 14, in Fig. I.], and the frame, [see No. 16, in Fig. I.] The batten, 2, is connected to a triangular lever by means of lever, d. Another vertical lever connects the lower part of this triangular lever to a projecting bolt, k, fixed to the guiding-rod of the griffe. Fig. viii. By raising the guiding-rod, thus raising lever^ k, in the direction of the arrow, the batten is thrown outwards, [see direction of arrow below c\ returning again to its former position at the lowering of the griffe. f indicates the place where the triangular lever is fastened (movable) to the projecting bolt, extending out of the frame, a indicates the place for the cylinder. Part i of the batten is movable at / in the direction of arrow, s, allowing the cylinder to be inserted. Part i is fastened (after putting the cylinder in at d), to 2 by means of the screw, n.

The dimensions for the cylinder in the present machine are as follows : = 2 Y^inches. = I Height of cylinder, = Width " " = " " lantern, = Average length of spindle, = This cylinder is carried in the batten, the latter moving in the groove provided for it under lo, Fig. I.

After coming in contact with the catch it still moves until the cylinder has performed a complete turn. The cylinder is steadied in the required position by the hammer pressing by the means of a spring towards the lantern from below. THE HAMMER. Fig. X. illustrates the hammer as attached to the batten ; a to d, (equals 3 inches in width in our present illustration), represents the head of the hamnv^r, i ] forming the foundation for steadying the cylinder in its turning. The i^^^ill hammer is pressed for this purpose towards the cylinder by means of the spring, s to r. Parts k and k guide the hammer in its up and down movements, and are solid parts of the batten. By turning the cylinder the hammer is pushed down in the direction of the arrow, thus com- pressing the spring, which returns to its normal position after the cylinder has completed its turn, ready for being advanced towards the needle-board. The following are accurate measurements of this part of the machine : Height of head of hammer at a and d, Thickness of hammer-head, e to c, Height of hammer-head when at rest o above the top guiding part, c to 0, Width of the guiding-rod, c to d, Thickness of " top guide, to " "lower guide, "y^ to r, Distance between these guides, Total height of guiding-rod, inch.

As before mentioned, the heads of the needles are passed through the needle- board. A drawing of this board, representing the front view, is shown in Fig. XI. The following are the dimensions : aX.o c, = gyi inches. « to = 2% inches. Each side of the prism, always technically called XI. the cylinder, has a protruding peg about ^ inch in length. When in contact with the needle-board these pegs enter the black holes shown upon either side in drawing. The 208 needles and holes in the present machine are represented by a small spot for the former with an outside ring for the latter. The lifting of the griffe, which in turn also operates the other parts of the Jac- quard head, as explained before, is not always produced from above : very often this lifting is arranged to be done by means of a lever arrangement from below the griffe. This method of working the mech- anism in the Jacquard machine is illustrated by Fig. XII., representing the perspective view of a 400 Jacquard machine, (W. P. Uhlinger, builder). Fig. XII. Fig. XIII. represents the same machine adjusted to ip^ the loom. On the longer r arm of the lever a series of holes are found. These regulate the height of the lift by the vertical rod which provides the required movement. The nearer this rod is adjusted to the Jac- quard head the higher the I lift of the Jacquard harness, thus formino- the shed. THE JACQUARD CARDS. Fig. XIV. represents a single Jacquard card, as re- quired for the 200 Jacquard ]8 machin*;,, ^ of its actual size. This shows 26 rows of holes in its width and 8 rows in its depth, 208 holes. These holes are shown in black, one for each hook in the machine. Besides these a large hole on each side permit the pegs of the cylinder to enter into the needle- board. The cards are interlaced in an endless arrangement. .1 o' a o •i-.o' Fig. XV. Fig. XIV. Fig. XV. illustrates four cards laced together. The large holes (marked d in drawing) are peg holes to receive the pegs, /i, h\ h", h'", etc., of the cylinder, as shown in Fig. IX. These pegs are movable so that any small variations at cutting with different card-stamping machines can be rectified. The paper used for the cards must be of sufficient thickness to resist the wear caused by the needles, as well as to give steadiness to the cards when resting in the pegs of the cylinder. The cards are interlaced in an endless arrangement ; hence, one card is brougrht after the other in rotation towards the needles. The cards only refuse service by not fitting properly on the cylinder, i. e., if the peg holes are too near together or too far apart ; or if the cards are warped, which is liable to happen in a damp workshop. A careful examination of the cards fitting on the cylinder is absolutely necessary, otherwise a wrong lifting of the hooks destroying the cards by the pegs punching new holes would result. The cylinder with cards perfectly cut must be set so as to allow the needles to penetrate into the centre of the holes stamped for them in the card. Sometimes the cylinder is set too high or too low — too far in front or too far in rear. To ascertain the proper position, lift the machine and place some paint, or grease from the machine, on the heads of the needles. Afterwards let the machine " fall in," which will bring the cards against the heads of the needles, producing an impression and indicating the exact position of the needle-heads. The cyhnder is always set in its proper position when no marks are made by the entering needles on the margins of the stamped holes and where there are no holes the impression left by the needle head must be equally distant from the surrounding holes. To eet a clear understanding of this examine Fig. XVI, illustrating six different impressions of the needles. The circle shown with full lines in each of these six illustrations represents the correct position of the circumference of the hole, and the dotted circles the various errors that may exist. Fig. XVI. 19 Fig. A shows the cyhnder set in its proper place, which is indicated by the impression of the needle in the centre. Fig. B shows the cylinder is set too high, as indicated by the impression of the needle. [See arrow.] In Fig. C the cylinder is set too low. In Fig. D the cylinder is set too far to the left. In Fig. E the cylinder is set too far to the right. In Fig. F the cylinder is set too low and too far to the right. In Fig. G the cylinder is set too low and too far to the left. In Fig. H the cylinder is set too high and too far to the left. In Fig. K the cylinder is set too high and too far to the right. If the machine produces wrong lifts of the hooks and the trouble is not found in the setting of the cylinder, nor in the hooks or needles, then ascertain if the iiii li iiiii i!L/ V V V VV v v Fig. XVII. cylinder is adjusted by means of the lever arrangement, close enough to the needle- board ; for if it is not, the hooks will not be pushed far enough from the griffe-bars, and by raising the latter a wrong shed will be produced. When using a great number of cards in a set they are made to fold into a " rack." This is done by attaching a wire i to 1% inches longer than the cards at the junction of, say every 1 2th, 15th, or 20th cards. [See c at Fig. XV.] The cards fall through a wooden frame, Fig. XVII., but the wires attached to the cards, being longer, can not pass through, and the cards will remain suspended, and subsequently fold together in a very compact manner. In Fig. XVII. we illustrate 156 cards arranged with wires atttached to every twelfth card, as follows: between cards 156 and i, 12 and 13, 24 and 25, 36 and 37, 48 and 49, 60 and 61, 72 and 73, 84 and 85, 96 and 97, 108 and 109, 120 and 121, 132 and 133, 144 and 145. 20 At e,f, are shown prisms of the size of the cyhnder, by which the cards are guided and regulated in their run towards the cylinder, (direction of arrow) ; i and h represent round rollers, also placed in rack for guiding cards after leaving the cylinder, c ; a and the needle-board; c and d, the needles of the machine. 6* represents the wires as inserted in cards for holding them in the frame. THE JACQUARD HARNESS. To the lower end of the hooks {c. in Fig. V.) the neck-cords are adjusted. The latter are passed separately through one of the corresponding holes of the perforated bottom board (Fig. II.) To these neck-cords are fastened the leashes of the Jacquard harness about ^ to i inch above the frame containing the rods which guide the neck-cords vertically as the hooks are raised and lowered. The different harness- cords are threaded through the comber-board in various ways called "Tie-ups," which will be explained later. The Comber-board and Methods of Figuring for it. There are two kinds of comber-boards used upon Jacquard looms: I St. Comber-boards made of a solid piece of material, either wood or porcelain. 2d. Comber-boards made in strips of either of the materials above named, and adjusted afterwards in a wooden frame. Comber-boards Made of a Solid Piece of Material. Before ordering a comber-board, it is necessary to know the texture of the fabric in the loom, and also the number or size of the machine to be used ; for the number of holes per inch in the comber-board is regulated by this. Afterwards, we may, if we choose, arrange the number of holes in depth of the comber-board, according to the number of griffe-bars in the machine, (guided by the fabric to be made). We may have eight griffe-bars in the machine, and arrange the comber- board 4, 6, 8, lo, 12 rows deep ; or we may have 12 griffe-bars in the machine, and arrange the comber-board 12, 10, 8, 6, 4 rows deep. Rule: The number of holes to one inch in the comber-board must equal the texture of the fabric to one inch in loom. Example : Suppose a fabric with a texture in the loom of 100 threads, and we are to use a 600 Jacquard machine, with 12 rows. The width of the fabric in the loom is to be 36 inches. Required: The number of holes in the width of the comber-board. Answer: 100 X 36 = 3600 holes in the comber-board. 3600 -^- 1 2 = 300, the number of holes in width. The width and depth of the comber-board are regulated by the width of the cloth required and by the design to be used. The greater the number of rows in depth the closer they must be ; the same is true of the width. , It is necessary to take care not to have the comber-board too deep, as the consequence would be a bad shed ; furthermore, we must not have the holes too close together, as in a high texture this would make trouble in the weaving through the catching of the heddles with the warp, and also cause useless chafing of the warp- threads and the heddles. The Changing of Solid Comber-boards for Different Textures. In Jacquard work we generally use the same texture, or as near as possible, as the loom is tied up for ; but changes are sometimes unavoidable. If we reduce the texture of the fabric in a Jacquard loom tied-up for a solid comber-board, we must reduce proportionally the number of hooks and needles used in designing, and hence the number of heddles used per inch. These heddles will thus be left empty when drawing in the warp. To accomplish this lift the full machine and throw the hooks not to be used from the knives, lowering in this way every mail which is not to be used. Sometimes there may be only one, two, three, or four hooks to be thrown off, on account of the design. At other times it may be necessary that one-eighth, or one- fourth, or even one-half of the whole number shall be dropped for this purpose. For instance, suppose we have a dressgoods design of 596 threads and a 600 machine. These four ends left off the 600, if in 6, 7, 8, or more inches in width, would not affect the fabric nor the cost to any great extent; hence we may leave out the first or last four needles of the 600. Suppose we have a texture of 100 in the comber-board, to lower to 66 ends per inch. 66 ends, or the nearest even part of 100 (66^) is ^ of 100; hence, we only need two-thirds of our machine ; and as the same is supposed to be arranged 12 rows deep, we need ^ of 12 rows, or 8 rows. The four rows thus found necessary to drop may be dropped from the ends, or alternately, as follows : Every alternate 2 rows taken, i row missed, 4 times over, = 1 2 rows. Or, 2 rows missed, 8 rows taken, 2 rows missed, = 12 rows. Comber-boards made in Strips and Adjusted afterwards in a Frame. By these comber-boards which are used to a great advantage on narrow loom work up to 36 inch fabrics, we can change the texture for the fabric ; for the strips composing the comber-board may be drawn apart, thus changing the higher texture to lower ; whereas in a solid comber-board this could only be done by re-tying the harness or changing the number of needles used in the machine. To give a clear understanding Figs. XVIII., XIX., XX. are needed. Fig. XVIII. represents an 8-row deep comber-board, a, b, c, d, composed of 10 strips which are set close together. By examining each strip 5 cross-rows of holes will be found, making the whole number of holes 400. Suppose the comber-board as represented in Fig. XVIII. is intended for a texture of 100 ends per inch ; this will give for the width of the fabric {i, k, to /, m,) 4 inches. In Fig. XIX. the comber-board is arranged for a texture of half as many ends, or 50 holes per inch, and the 10 strips are arranged accordingly ; the empty places Fig. XIX. Fig. XVIII. between the strips are of same size as the strips themselves, and the fabric design below the comber-board is arranged to correspond. Fig. XX. illustrates the sectional cut of the comber-board used in l^'"' 3 drawings, Figs. XVIII. and XIX., and the letters indicating the dif- FiG. XX. ferent parts of these figures which correspond. Divisions of the Comber-board. Under this heading we classify one repeat of the arrangement of threading harness-cords in the comber-board, and therefore one repeat of the design of the fabric. We find fabrics in which are used one or more divisions of one system of threading harness-cords in the comber-board ; again, there are others in which one or more divisions of one system are combined with one or more divisions of another, or even of two or three other systems. ■(olt. Heddles for the Jacquard Harness. After the harness-cords are threaded through the comber-board the heddles are adjusted. Of these there are two kinds : A. The twine heddle, containing the mail for holding the warp-thread. B. The wire heddle, similar in its construction to the regular heddle, used in the common harness-loom. These are very little used, and only in fabrics of a low texture. Fig. XXI. illustrates a regular twine heddle one-fourth of its actual size. d represents the mail, through the eye of which the warp-threads are passed. a, the adjustment of the heddle to the harness- cord. Tig. XXI. c indicates part of the lingo for weighting the heddle. 28 Fig. XXIII. Fior.

Fie. XXIII. illustrates the averao-e position of the mail in a loom, a, breast- beam of the loom, c, the warp-beam or guide-beam over which the warp runs on its way towards the harness, d, the position of the heddle. the lingo. The "Leasing" of the Harness. This requires a clear conception of the rotation in which the different heddles are threaded, according to the tie-up empkn ed. Two methods are in use: ist. The heddle nearest the weaver is the first to be threaded, and the heddle of the same row in rear of the comber-board is the last. 2d. This principle reversed, thus arranging the leasing from rear to front. The latter method is the one most generally observed. Every row in depth of comber-board is leased separately, and in rotation secured to the lease-twines, a and d, in Fig. XXIV., thus forming an uninterrupted line of heddles through the entire Jacquard harness. Throuo-h these heddles the warp is afterwards drawn in rotation. Fig. XXII. TYING-UP OF JACQUARD HARNESS. 1. The Straight-Through Tie-up. Fig. XXIV. This tie-up contains in its principle the foundation of all the others. Three methods are in common use, which we will now explain. ist. The Jacquard Harness threaded on the machine in the direction from Front to Rear. This tie-up is represented in Fig. XXV. As mentioned in the" heading of this article, the Jacquard harness, or the leashes, are fastened to the machine in rotation from front to rear, the threading of the comber-board being done from rear to front. The comber-board is in three divisions. The machine used for illustrating is a 400 Jacquard 8-row machine, and the comber-board used is also 8 rows deep. This method of tying-up of the leashes forms what is technically known as "open harness." As the drawing is designed to explain a 400 machine, 8 rows drawn in the comber-board, also 8 rows deep, one row in height of the cylinder will equal one row in depth on the comber- board. In examining the illustration the eye must follow the line connecting the 25 numbers on the neck-cords to the corresponding numbers near the holes on the comber-board. If this be done, the tie-up will readily explain itself. It will also explain the method of procedure if a machine is used containing a dif- ferent number of needles and hooks, and a comber-board having as many rows in depth as there are griffe- bars in the machine. For example, a 600 machine, with 12 griffe-bars, needs for this tie-up a comber-board 1 2 rows deep ; and a 200 machine, with 8 griffe-bars, requires a comber- board 8 rows deep, etc., etc. The drawing shows a comber- board with 3 divisions, each division furnishing one harness-cord to each neck-cord, making in all three har- ness-cords to every neck-cord. The same tie-up will apply should the drawing contain a different number of divisions. The illustration shows only the first and last rows of each division in the comber-board, and also the first and last rows of neck- cords. The design below the drawing represents a damask fabric to be executed on this tie-up, requiring the whole number of needles for one repeat of the pattern of 400 threads. In designing for these tie-ups it is necessary to arrange the design' to repeat itself in the number of needles that will be used in pro- ducing the fabric. The first and last threads must connect with each other, without interruption, forming a continuous design over all the divisions. Thus we find, in fabric design of a damask towel. Fig. XXVI., the repeat (division) from A to B. In the centre of the design marked a, and the main part of the border marked c, we find one repeat; whereas borders ^ and d' repeat 8 times. In the fabric illustrated by design, Fig. XXVII., again a damask towel, the repeat, or one division, is also indicated by A to -B. The centre of the fabric, a, repeats twice in one division ; borders and'/5' repeat four times in the same distance; whereas the main design of the border indicated by c requires one complete division. Fig. XXVI. 26 Fig. XXVII. 2d. The Jacquard Harness threaded on the machine from Rear to Front. This is the second method for the straight-through tie-up, and is illustrated in Fig. XXVIII. The Jacquard harness is fastened to the machine, at the neck-cords, from rear to front. The threading of the comber-board is also from rear to front. In this method the work of attaching the leashes to the neck-cords is commenced in the rear instead of the front of the machine, thus giving a different view and arrangement of the tie-up. This disposition of the threads is called a "sectional harness arrangement." The illustration shows a 400 Jacquard or 8-row machine, in connection with an 8-row deep comber-board, with one row in the comber-board requiring a corresponding row on the face of the cylinder. It will also explain the method of procedure with this tie-up in Jacquard machines with comber-boards of different sizes. ' Fig. XXIX. represents the perforated board at the bottom of the machine through which the neck-cords pass, attaching the leash to the neck-cords. The first row, containing neck-cords numbered i, 2, 3, 4, 5, 6, 7, and 8, and the 50th row, containing those numbered 393, 394, 395, 396, 397, 398, 399, and 400, are the onfy ones shown in Fig. XXVIII. illustrating the tie-up. The comber-board is divided KOOK!. 28 into four sections ; hence, the drawing, as represented in Fig. XXVIIL, calls for a fabric with 1600 ends in width. 400 ends, or any number dividing into 400, can be used for the repeat of the pattern. The method followed in the illustration may be applied to any size of Jacquard machine, and also to any required number of divisions in the comber-board. In ascertaining the number of hooks or needles for one repeat of the design, determine accurately if the repeat of the weave employed for binding the ground or the figure divides evenly into this number. For example, take bottom board. Fig. XXIX., calling for 400 hooks and 400 needles. Suppose the ground weave to be an 8-leaf satin, and the design to repeat once in the 400 hooks. 400 8 = 50 repeats, showing an equal division But suppose a 12-leaf satin is used; it is obvious that 12 is not an even factor of 400, as the division shows a remainder of 4. To dispose of this remainder two methods are open : First. Omit last 4 ends and use only 396 hooks, a multiple of 12, giving 33 repeats ; or, Second. Add 8 hooks from the reserve rows, elsewhere previously alluded to, thus increasing the num- ber to 408, which is also a multiple of 12, giving 34 repeats. 3d. The Straight-Through Tie-up on the English System. The English system, which is widely used, has the Jacquard ma- chine so adjusted upon the loom as to have the cylinder lengthways, runnine in the same direction as Fig. XXIX. comber-board ; or, what is the same thing, running in the direction of the width of the fabric. [See Fig. XXX.] The 8 hooks of one cross-row (one hook from each of the 8 griffe-bars) run in the •«•' *^ •'^ ^fC #/r \if »ii •n •'"j •9 '^- • 1} ',11.^1/ •if ••<)' •'f ■-- #.* '.•30 mi^ •if •ii" -1' « « •li •ir "J/, tSS^-r « • i«~ •V-'/ J»V^ • -- » • • • • -- ft • • • « • •'St •sy . • • • • • • m^sr - 9- • • •' « • • •Y-3 - • •% • • ♦ ••' •SI « • • « • • .Vl !• • • • f ' .a^^ * « • • :» •) • • • • 1^■ ^ • • • * • ^« • • « «' » ^ • • • • 1* !♦ • • • • • • • « • «•••.•')«• ^ • ■•\ * « ^' m^oom'^ff'* *' • <* *' m 9: •' • ♦ « •«««•'•• m, •■ ^< • • ♦ ♦ '0 • * «^ • « • 03^0 •- 0 0 t-- 0 0 0 - ^-i/^e 0 0 0 0 0 0 0 0 3y^ m-3ys'm 0 0 0 0 • ^Sl" » » 3*4 • • • • — ■ 03f^0Jf/0 3fa^jSf„3SS,3S;'^ 0 0 '/oo * i?9 • ife 0 3^7 03fi • 3^S « J • 3f-3 _ - x. x^;> x*"- «f»' iT'l K.t,% -5 ^" , Jl* , f,- . 6 . 7 ' 9' • /o ■> , // • /3 • ■ /S - A.* //• • zo * U ' ix, ' ' J/ dr.. 3y. 3J>.. 3^ . Hi , ¥^ 29 direction from the cloth beam towards the warp beam. Having the same number of rows in depth, in comber-board as there are griffe-bars, one may readily see the advantages of this tie-up. The first row in depth of the comber-board contains harness-cords from neck-cords i to 8. The second row deep of comber-board contains harness-cords from neck- cords 9 to 1 6, finishing each divi- sion on the last (25th) row, with harness-cords from neck-cords 193 to 200. Should we have a 600 ma- chine, with 12 rows, the comber- board would also have 12 rows, as the 600 machine contains 12 griffe-bars. The first row of the comber-board receives the har- ness-cords from Nos. i to 12; the second row from Nos. 13 to 24, and so on, finishing on the last (50th) row of comber-board with 589 to 600. II. Straight-Through Tie-up for Repeated Effects, in one Repeat of the Design. This method of arranging the tying-up of the Jacquard harness is based upon the necessity for producing patterns having a larger number of warp-threads than the Jacquard used has nee- dles. The principle to be ob- served is found in producing small effects which repeat them- selves in the general design. The number of cords for the leashes depends upon the frequency with which these repeats occur. Fabrics with stripe effects offer greater opportunities for reducing the number of hooks and needles than other designs. Fig. XXXI. illustrates such a design with its tie-up, using a 400 Jacquard machine with 8 rows. The pattern shows four distinct effects, as follows : A, requiring rows i to 16, inclusive; or harness-cords i to 128, inclusive. B, requiring rows 17 to 21, inclusive; or harness-cords 129 to 168, inclusive. C, requiring rows 22 to 34 ; or harness-cords 169 to 272, inclusive. D, requiring rows 35 to 50; or harness-cords 273 to 400, inclusive. In this fabric we find 2 full repeats of the design: first, E to F; second, E" to Fig. XXX. 30 F'\ thus requiring two divisions in the comber-board, as indicated by the vertical line between F and E". The next subject to consider is the different arrangement of repeated effects in one division. Commence at the left-hand side of the fabric sketch with effect A, which repeats only once in one pattern or one division. The illustration shows two divisions, and also that each hook of rows i to 1 6, inclusive, in the first division can be connected with each hook of rows i to i6, inclusive, in the second division, because these rows produce the same effect in the design, which repeats itself in these two places. This connection forms what is technically called a leash, and it will always be found that for every harness-cord a leash contains, there will be found a repeat in the design to correspond. Effect B is repeated four times in the design, or in each division. By having two divisions for the illustration we find that to produce the necessary repeats in the design each hook of rows 17 to 21, inclusive, requires 8 harness-cords to each leash. Effect C repeats twice in one pattern or one division. Having two divisions for the illustration, each hook of row 22, including row 34, requires 4 harness-cords to each leash. Effect D repeats once in pattern, once in division. This will give a result similar to A, two divisions, row 35, including row 50, with two harness-cords to each leash. This tie-up illustrates the first row of every effect, and also the last leash, 400. Adding the number of warp-threads in the full repeat of the pattern, we have: Effect A = 128 threads. " B = 40 " C= 104 " B=z 40 " " £> = 128 " B = 40 " " C = 104 " " B = 40 " 624 threads. Or, in other words, we are producing with a "straight-through tie-up for repeated effects" on a 400 Jacquard machine, a design, which would require a 600 machine on a common straight-through tie-up, including the two reserve rows, or 624 needles ; in other words, a saving is made of 224 needles in one full repeat of the pattern. In designing for looms tied up for similar styles, the repeats of effects must be kept in mind. The general style of every design may be changed, but the arrangement of the repeated effects cannot be altered without changing the entire Jacquard harness. 81 III. Straight-Through Tie-up of a Jacquard Loom having Front Harness Attached. As mentioned in the beginning of this work, every Jacquard machine contains two reserve rows, which may be used for various purposes. One of the purposes to which these rows are frequently put is the enlargement of the design of the fabric by using harness on the front of the comber-board, technically known as " front harness." For example, in damask table-cloths, we may use the Jacquard harness for producing the border of the fabric. The centre part may be produced with front harness, forming a checkerboard, or some similar effect. This process may be reversed by designing the centre of the table-cloth for .the Jac- quard harness, and the border for the front harness. A third method is to design part of the centre and part of the border for the Jacquard harness, the other parts being designed for the front harness. This tie-up is also used to a great extent in the manufacture of dressgoods, etc., where stripe effects produced by the front harness, alter- nate with floral or geometrical designs produced by the Jacquard harness. In Fig. XXXIII. the centre of a table-cloth cover is shown to further illustrate this method of tying-up. One-half of the width of the design is for the Jacquard harness ; the other half is for the front harness. To pro- duce the required checkerboard effect these front harness are used here in two distinct sets. The 1st set = 5 harness, working on the 5-leaf satin warp for face, alternating with the 2d set = 5 harness, working on the 5-leaf satin filling for face. If only 8 front harness should be used for the design, we should have the 1st set — 4 harness, working on the 4 harness broken twill warp for face. 2d set = 4 harness, working on the 4 harness broken twill filling for face. Set I to alternate with set 2 to form the check. Care must be taken that the number of checks formed by the front harness are evenly arranged to the figured part of the fabric. For example. Fig. XXXIII., in the front harness part of the design shows 5 warp checks and 5 filling checks in one row, = 10 checks. Fig. XXXII. 32 Suppose lo front harness are used and 20 warp-threads allowed for each check; then 20 X 10 = 200 warp-threads, all used for effects by the front harness. This requires 200 warp- threads for figure effects to be used by the Jacquard harness. The repeat of the pat- tern is therefore 400 warp- threads, which is produced by straight-through tie-up, front harness attached, with 200 hooks and nee- dles for FIGURE PART of the design, plus 10 hooks and needles for checkerboard PART of the fabric taken from the 16 hooks and needles of 2 reserve rows, leaves 6 hooks and needles for selvedge, etc. As previously stated, the front harness may be used for dressgoods fab- rics. In this way the de- sign may be enlarged to any required extent. Fig. XXXII. illustrates this method, using an 8-row Jacquard machine, with 4 front harness adjusted, in common use for the manufacture of dressgoods fabrics, damasks, etc. Fig. XXXIV. shows a fabric designed for dressgoods forming an all-over-set pattern. In this design parts F and F" must be executed with the Jacquard ,j leashes; parts G and G can be executed with front harness. For example: parts /^andT^' require each 100 hooks, the ground part to be woven in 4 harness broken twill. We find the answer as to number of warp -threads in the repeat and number of hooks re- quired for weaving as follows i Fic. XXXIV.

IV. The Centre Tie-up. The centre tie-up, also called the point tie-up, has for its purpose the enlargement of the design in fabrics such as table-covers, dressgoods, etc. This tie-up resembles in its principle that of a common // point-draw on the harness-loom. After drawing ^ from front to rear once straight through the entire set of harness, draw from rear to front Fig. xxxv. and repeat. The only difference between harness-work and Jacquard work is ' in the fact, that with harness we commence to draw in from the first harness straight through to the last, A to B, and back again, B to C; but with the Jacquard tie-up on this method this is arranged through the threading of the comber-board, having a straight-through leasing of the heddles and drawing in of the warp. In Fig. XXXV. there is a clear illustration given of the principle of the centre tie-up on an 8-row comber-board A, A', (B, (2'. In laying out the comber ' -ard, it must be divided by the line C, C, into two equal parts, D, C, and C, D'. I le part A, A', C, C, of the comber-board, we commence threading with leash i at the left- hand rear corner, running in succession towards the centre, as indicated by the arrow on this part of the comber-board. In part B, B', C, C, the threading begins in the opposite corner, to the right- hand in front, with number i leash, threading in rotation the number of leashes from the front towards the rear, as again indicated on the figure by an arrow. After leasing and threading the harness, No. i leash will contain in its two mails the first and the last of the warp-threads, as indicated in Fig. XXXV. by the numbers, and the rotation by the arrows, S and S'. 34 Fig, XXXVI. represents this centre or point tie-up ap- plied to a 200 Jacquard ma- chine ; comber-board, 8 rows deep; two full divisions; A, B, the first division ; B, D, the second division ; C andC' form- ing the centre in each division. This machine will, if tied-up in this manner, produce a design requiring 400 warp-threads. We must arrange the design for this tie-up so as to repeat forwards and backwards re- spectively in the centre. Such a design will run upwards at a given angle to a definite point, then it will return by the same angle in an opposite direction until it reaches the base from which it originally started. In this manner design, Fig. XXXVII., is constructed. A, B, C C\ D, correspond with the same letters used in Fig. XXXVI. ; hence, it will readily Fig. XXXVI. explain itself, as well as the method to be observed in de- signing for this kind of tie-up. The design runs straight through from A to C and re- peats itself backwards from C to B, finishing at B the first full division. B-C equal A-Q C-D " C-B, forming the second division. Any changes as to different sizes of machines, rows deep of comber-board, or number of divisions, must be executed upon the principle explained in this article. Fig XXXVII. V. Straight-Through " and " Point " Tie-ups Combined. A. — For fabrics reqtdring for their centres a, straight-through tie-up and for their borders a point tie-up ^ one-half division of it for each border. Fig. XXXVIII. These tie-ups are used to a great extent for napkins, handkerchiefs, scarfs, and similar damask fabrics, in which the centre part of the fabric is worked on the straight- through method ; the borders on each side on the point tie-up, repeating equally from 36 centre towards the selvedge. In the other two borders to be woven at the beginning and the end of the fabric, the same principle is observed, thus producing four corner squares, only two of which need be designed, as the other two repeat through the arrangement of the tie-up, which must repeat equally towards both sides of the border at the connecting places. Fig. XXXVIII. illustrates this method of tying-up a 200 machine, using 192 hooks and needles, equal to 24 long rows of a regular 8-row deep machine. The machine is divided into two sections, as follows : Needles i to 96 for the ist section or centre. 97 " 192 2d " " the border. 4 repeats of centre, = 4 x 96 = 384 ends. 2 repeats of border, one for each side,r= 2 x 96 := 192 " 576 ends in fabric, not including selvedge. The drawing represents four divisions for the centre, hence four harness-cords for each leash. The border, having only two repeats in the fabric, will contain only two harness-cords to one leash. In the drawing the first full row of the ma- chine is indicated, which is equal to the first row deep of every centre division ; containing harness-cords i, 2, 3, 4, 5, 6, 7, and 8. We also show (heavy line) the last centre leash, No. 96 being the last hook of row 12 of the machine. The borders A' and A" are from the same design, but the figure runs in an opposite direction in each one, as indicated ^ by the arrows in the comber-board above. Border^' commences with harness-cord from leash" 192, ending with harness-cord from leash 97, near the centre design. Border^" ^ D commences with harness-cord from leash 97, near the centre design, ending with harness- cord from leash 192 near the selvedge. The great difficulty to be overcome in arranging these patterns for the loom is in the union of the two tie-ups, the straight- through and the point. As previously stated, the borders J.' and A" are made with the point tie-up, while the remainder of the borders are made with the straight-through tie-up. The com- bination of these two tie-ups occurs in the corner squares of the border, and the arrangement must be such as will permit the two sides of the corner patterns to properly unite with the design for the balance of the border.

The following particulars will explain the entire procedure : 200 needles and hooks are used for borders, point tie-up, once through, equals V2 division for each border. [See letters B and B' on comber-board.] be d b a 400 needles, and hooks are usedvfor centre, straight tie-up, one repeat.

Fig, XL. is a fabric design executed on this principle : a to b, border ; c X.o dy centre ; b \.o a, repeat of the first border. Straight-Through and Point Tie ups Combined. B. — For fabrics requiring for their centres a straight-through tie-up, and for their border on point tie-up one full division for each border. This arrangement of both foundation tie-ups resembles the preceding. The only difference is found in employing the full division of the centre or point tie- up for each border instead of the half division. ^\ ©IS®" M 0A^f if 1- V o Fig. XLII.

The centre of the fabric requires 400 needles and hooks in 6 repeats or divisions, or 400 X 6 = 2400 warp-threads. The border calls for 204 needles and hooks, point tie-up, one full division for each side, or 204 X 2 x 2 — 816 warp-threads. The arrangement of margin and selvedge, as applied on each side, is explained 40 separately through ground plan of comber-board by fig. XLII. The margin calls for 8 needles and 8 hooks in machine, 6 repeats of same for each side, or 96 warp- threads. The selvedge is formed by 2, 4 or 8 needles, (working plain), and has 24 heddles for each side or 48 selvedge-threads in warp. These selvedge ends may, if preferred, be drawn two ends in one heddle. By adding these different systems of threads we find : Centre = 2400 warp-threads. Borders = 816 " " (814 if point drawn only once.) Margin z= 96 " Selvedge =^ 48 " 3360 threads in warp.

In drawing. Fig. XLI., we only illustrate centre and border of the tie-up, so as not to confuse the eye by too many lines, and, as mentioned at the beginning, employed Fig. XLII. for illustrating the ground plan for selvedge and margin. In selvedge and margin the harness-cords are indicated by consecutive numbers, thus : Margin, i to 48. Selvedge, i " 24.

Not only will drawings and explanations lead to a thorough understanding of the procedure, but they will also readily show the great variety of textile fabrics to which the principle of this tie-up may be applied. Fig. XLIII. illustrates the margin arranged 8 threads for each row, and 5 rows or 40 threads for each side. The selvedge in this drawing is illustrated by one complete row of 12 double threads, for each side. The selvedge and margin holes are all represented shaded. The selvedge is marked 6" in addition to the number. The five margin rows are indicated each by figures i to 8. The 41 nearest row of border is also represented, being numbered 401 to 412, corresponding to Fig. XLI. This method of using only 8 rows of the 12-row deep comber-board is extensively used in fabrics of a common texture, employing an 8 harness satin for the margin as weave, which repeats once for each row in comber-board. Besides, a great advantage results from being able to tie-up 8 leashes threaded 8 rows deep in comber-board to the 8 hooks in i row of the machine, which the weave calls for. C B D Fig. XLIV.

XLV. 42 Straight-Through and Point Tie-ups Combined. C, — For fabrics havijig the centre for straight-through, with the border for straight-through and point tie-ups, {half divisions), combined. This method of tying-up is illustrated in Fig. XLVI., and the fabric produced in Fig. XLVII. With this method of tying-up is usually introduced an extra margin for the purpose of separating the ornamentation of the design, so as to permit of a clearer definition. This is tied-up on 8 needles and hooks, situated between border and centre, (24 ends) shown at margin (B in the design. The centre of the fabric, (two A B m?9 n. Fig. XLVTII. divisions only illustrated out of ten actually used), is tied-up on the straight- through method, requiring for its working, harness-cords i to 240. The border has the point tie-up in half sections ; these half sections have a straight-through tie-up design in its centre. Harness-cords 241 to 456 are used for the straight-through section, and 457 to 600 for the point tie-up section. The margin is produced by harness-cords 601 to 608, leaving 16 needles and hooks of the machine unemployed, which may be used for selvedge or other purposes. The drawing of this tie-up and fabric illustrates only the right-hand side. The complete design requires, in addition to the borders and margins, 10 divisions or repeats in the centre. The figure shows only two of these repeats and border and margins of one side, number of ends in the fabric is found as follows Centre, 10 X 240 Border, i P^^"^' 4X144- 576 ) The straight, 2x216 — 432 f between border and centre, 24 x 2 = 48 between border and selvedge, 48 X 2 = 96 Selvedge, not indicated in drawing of tie-up, — 2400 ends. =rioo8 " Margin, : 144 " : _4^ " 3620 ends in warp. 43 Number of harness-cords required for each leash: Leashes i to 240= 10 cords to i leash. ** 241 " 456= 2 " I " " 457 " 600= 4 « I » 601 " 608 == 18 " I " Selvedge leashes, if worked by 4 needles and hooks, = 12 cords to i leash.

Straight-Through and Point Tie-ups Combined. — ^or fabrics composed of the straight-through tie-up for centre ; the point tie-up, half divisions, and the point tie-up, full divisions, for borders. Fig. XLIX. This method of tie-up is used to a great extent in the manufacture of damask napkins, containing in its centre the monogram of hotels, restaurants, or private names. This effect is produced by floating the filling. In this manner, we find tie-up, Fig. XLIX., and fabric sample, Fig. L., executed, using for explanation a 400 Jacquard machine, certainly very low texture for these fabrics. In case of a higher texture being necessary, each effect must be propor- tionally increased. The machines most generally used for this class of fabrics are of the 900-1200 denomination. Taking the present tie-up into consideration, we find the centre for forming the monogram, containing 200 harness-cords tied-up straight-through the borders on 44 each side of the monogram, is executed on the point tie-up, one-half section for each side, taking loo needles and hooks, or harness-cords. The outside border on each side is executed on the point tie-up, using one complete division of it for each side; and in addition, loo harness-cords for the working. Adding these various divisions of the harness-cords gives the number of warp-threads as follows, viz. : Border, N, loo needles on point ^200 threads, (199 if omitting the point the second time). *• M, 100 needles on straight = 100 " Centre, L, 200 " " straights 200 " Border, 7]/', 100 " " return =100 " " A^', 100 " " point =200 ** (199 if omitting the double point.) 800 threads.

Straight-Through and Point Tie-ups Combined. E. — Mixed Tie-up. Containing in one repeat of the design the straight-through tie-up and the point tie-up, one full division, for the centre ; the point tie-up, in half divisions, repeating once through on each side of the fabric, to make the border. These arrangements of tie-ups are used to a great extent in the manufacture of damask fabrics of every denomination. The principle of using mixed tie-ups, Fig. LII., is found in the necessity of producing large designs, containing varied effects, with a proportionally smaller Jacquard machine. Under whatever management the straight-through and the point tie-ups are combined, their principle remains undisturbed. Every time we arrange a Jacquard loom on a mixed tie-up, we must consider that any subsequent design must be arranged with reference to the same principle as the one in use, •otherwise the work must all be rearranged, which would have to be done even for the smallest change in the number of ends for each effect. Take for illustration a damask fabric. Fig. LIII., handkerchief, bureau scarf, an square, etc. The details given will make the work quite plain : Part of comber-board from A to (2, or (b to C, illustrates one-half of the board and procedure of tying-up. The design below also shows only one-half of the fabric. Arrow, G, near comber-board, and arrow, M, near fabric, are placed to indicate the direction in which a repeat is obtained. The fabric will form its centre at D, repeating towards each border and selvedge. This is illustrated in the comber-board by the i-row deep, outside of line A, D. Harness-cords indicated by dotted lines. The threading of this last mentioned row, as well as the threading of the half division of the point tie-up, is indicated by arrows H and K, forming the centre by means of harness-cords 193 and 193. The straight-through tie-up part of the fabric is found between ^5" and F, containing 12 repeats in the centre, and also the same number in the lower border. In the comber-board is illustrated this arrangement, repeating the first row, containing harness-cords i, 2, 3, 4, 5, 6, 7, 8, twelve times, and the last hole of the third row containing harness-cord No. 24, twelve times. On the bottom of the comber-board these 12 repeats are indicated by 12 small arrows between parts E to F. The first row in the first division of the straight-through tie-up is completely 47 M.

The border of the fabric is arranged for harness-cords 25 to 192 on the point tie-up, having one-half division 48 on each side. Arrow L indicates the right-hand border. The border on the left requires the same harness-cords which are threaded in comber-board from right to left ; hence the borders of the fabric contain the same design repeating from the centre towards the selvedge. At the beginning we stated that the use of mixed tie-ups made it possible to employ a smaller size Jacquard machine for large designs containing various effects. The following analysis of Fig. Lll. shows very clearly how this is done. Number of warp-ends in one complete repeat in width of the fabric- Border, right-hand, = i68 threads. Centre, straight-tie, = 288 " . f = 168 pomt-tie, I _ <^ straight-tie, = 288 Border, left-hand, = 168 " 1248 ends warp in fabric. Number of needles required to produce the design : Border, =: 168 needles. Centre on straight-tie, = 24 needles. Centre on point-tie, = 168 needles. 360 needles required for producing the complete design, thus saving the difference between 1248 and 360, or 888 needles; all of which is accomplished through the use of the mixed tie-up. Number of harness-cords required for each leash : Leashes i to 24 contain 24 cords for one repeat of the entire design. Leashes 25 to 360 contain 2 cords for one repeat of the entire design. It is not always practicable to reduce the effects in a design to the lowest possible number of needles. On account of the changes in styles, it is best to arrange these tie-ups with a view to giving as much opportunity as possible to the designer. In the present tie-up experience teaches that it. will be more advantageous to arrange the straight- through tie-up either for 6 divisions to 48 ends each, or 4 divisions to 72 ends each. 360 needles, as figured at the beginning, require a 400 machine, or, counting reserve rows, 416 needles; hence we can, without tiisadvantage, increase 360 needles to 384 or 408, which will give a greater scope, if required, to make a new design. VI. The Straight-Through Tie-up in Two Sections. A. — Using machine and comber-board in two equal sections. This tie-up. Fig. LIV., is used on fabrics having two different kinds of warp, which, as a rule, are of different colors. One of these warps is shown working at B in the comber-board, and also at the bottom-board. The other warp employed for the figure effect is shown working at A. Fabrics that are made on this tie-up can also be made on the common straight-through ; but the work of designing and card stamping will be largely increased. In the illustration all the figure- threads, and also all the threads used for the weave (binder- threads) can be designed without interruption to each other. The breaking off of the figures is thus avoided, a thing quite impossible where the regularstraight-through tie-up is used. The drawing given herewith represents this straight- through tie-up in sections applied to a 200 Jacquard machine. The reserve rows are omitted. The machine and the comber-board, it will be observed, are divided into two even parts. In one part, the rear of A, of the comber-board we thread only in the leashes from needles i to 100, and in the other part, front of (S, from nee- dles loi to 200. Hence, the first row of the comber-board contains leashes i to 4 and loi to 104; the second row will contain leashes 5 to 8 and 1 05 to 1 08 ; the third row will contain leashes. 9 to 12 and 109 to 112, and so on, each division finish- FiG. LIV. ing on the last row (25th) with leashes 97 to 100 and 197 to 200. The leasing of the threads is always done by alternately thread- ing the harness-cords of section A with section (B. Hence, first thread of the warp draws in first mail of leash No. i ; second thread of the warp draws in first mail of leash No. 10 r ; third thread of the warp draws in first mail of leash No. 2 ; fourth thread of the warp draws in first mail of leash No. 102.

Using two machines and a comber-board having equal sections. Sometimes two or more machines are employed in producing fabrics having two systems of warps ; each machine working on its own system. In this manner Fig. LVI. is executed, representing a straight-through tie-up arranged for two Jacquard machines, 6" and H, in which the warp is drawn in the Jacquard harness as follows : one end from machine S, one end from machine H. For explanation two lOO Jacquard machines are used for the purpose of simplifying the arrangements of laying out and threading the comber-board. A larger Jacquard machine for the illustrations would require more leashes, and the explanation would be more difficult. The comber-board, a, b, c, d, is divided into two equal parts, kS and H. Each part containing the harness-cord for one machine only. The drawing of the tie-up is arranged for two divisions, and also readily explains any tie-up for more divisions. The leasing of the Jacquard harness, K, is arranged (as illustrated in the draw- ing by leash-rods p and r) to commence as follows : 1st end: harness-cord fastened to No. I needle of machine, S; 2d end to No. 1° needle of machine, H; 3d end to No. 2 needle of machine, S; 4th end to No. 2° needle of machine, H; 5th end to No. 3 needle of machine, S; 6th end to No. 3^* needle of machine, H; 7th end to No. 4 needle of machine, S; 8th end to No. 4'' needle of machine, H. These eight ends, forming the first complete row of the comber-board, will use the first row of both machines ; the second row of the comber-board will use the second row of both machines ; and so %, u p mtf> 74 »)e)tc(y,mTcU on, until every row of the comber-board, with corresponding row of the Jacquard machine, is taken up. In the drawing we have indicated, as usual, besides the first row, the last row of the machine and the comber-board ; or, in other words, we show the threading of Fig. LVI.

H. 51 This method of using two Jacquard machines, on the principle explained, is employed on Jacquard looms for dressgoods figured with an extra warp, on uphol- stery goods, and similar textile fabrxs. Fig. LVII. shows a fabric design for a curtain, to be executed on the straight- througa tie-up in two sections. C, C/sm£ one machine and one comber-board: the machine unequally divided and the comber-board equally divided. To explain, take the regular upholstery fabric tie-up known as "petty point," on a 600 machine 12 rows in depth. 600 12 = 50 -\- 2 rows reserve =52 rows in width. We find used — I row for selvedge. 10 rows for binders ((S). 41 rows for figure [J), 52 rows. 41 (rows figure) X 12 (needles for one row) = 492 needles to be used for figure. 10 (rows binder) x 12 (needles for one row) — \20 needles to be used for binder. Suppose we have four divi- sions in loom, hence, four harness- cords to one leash, for the figure section, or 492 X 4 = 1968 ends of warp used for figure, 1968 threads of figure warp require the same number of threads of ground warp, which must be divided by 120, the number of needles and hooks set apart for it in the machine, or— as each needle and hook carries one leash — 120 leashes. 1968 -f- 120 — 16 repeats ; and 48 leashes, or four rows in the machine, must each have 17 harness-cords carrying 816 threads ; and 72 leashes, or six rows in the machine, must each have 16 harness-cords carrying 1152 threads, = 1968. VII. Tying-up a Jacquard Harness for Figuring Part of the Design with an Extra Warp, (part for Two Sections, part for Single). This tie-up Tthe character of which is indicated in Fig. LVIII.) is used for textile fabrics having two distinct warps in part of the fabric, and a single warp in the Fig. LVII. 52 remainder, for ground only. It will readily be seen in the drawing which explains this tie-up that one part of the fabric will have to contain more ends of warp per inch than the other, as the figuring is done with an extra warp upon the regular ground cloth. The number of ends of ground warp per inch will, as a general rule, be the same Fig. LVIII. throughout the fabric. In Fig. LVIII., explaining this method of tying-up, the tex- ture is twice as high in the figure stripe as in the ground part of the fabric. If 40 ends of warp per inch are used for the ground, 80 ends per inch must be used in the figured part, to C, (B' to C). 53 A 200 machine is used in the illustration, divided as follows ; 150 needles for the ground over the entire fabric, A to (B". 50 needles for the figure effects, (S to C, and (B' to C. The comber-board, therefore, must be arranged accordingly, (2^ divisions in drawing executed). The depth of the comber-board is divided into two parts: H, M, M, K, the first ; M, N", O, P, the second. The first contains leashes fastened to neck-cords attached to needles 151 to 200, or the figure part, and ; the second contains leashes fastened to neck-cords attached to the needles i to 150, or the ground part for the entire fabric. In the drawing of lines showing the harness- cords of the Jacquard harness we have only indicated : A. The ground part, leashes Nos. i, 2, 3 and 4 in rotation, and No. 150. This last leash of the ground warp we have indicated by a heavy line. B. For the figure part, needles 151 to 200 are used. Leashes 151, 152, 153, 154, are indicated in rotation, also the leash operated by hook 200 ; this latter one being also lined more distinctly than the others. These explanations readily show how to adapt the tying-up for any textile fabric made upon this principle to any number Jacquard machine. VIII. The Straight-Through Tie-up in Three Sections. The straight-through tie-up in three sections, which is illustrated by drawings, Figs. LIX. and LX., is largely used in the manufacture of fancy plushes and velvets, and also in the construction of any other kinds of fabrics in which the face is figured in three systems of warps, or in two systems of warps for the face and one system for the binder. If it were required, t!iese fabrics could be made on the straight tie-up, (Figs. XXV., XXVIII. and XXX.), but, as will readily be seen, they may be worked to much better advantage, both for designing and card-stamping, upon the method shown here. Fig. LIX. illustrates the method of adjusting the leashes to the neck-cords and threading the comber-board. In the example, we use for describing the method a 900 Jacquard machine, and follow the English system for placing it on the loom. The machine is divided into three sections: Section i, using hooks and needles i to 300 ; Section 2, using hooks and needles 301 to 600 ; Section 3, using hooks and needles 601 to 900, leaving the two reserve rows (generally found in every machine) out of the illustration. The comber-board is divided into two divisions lengthways, (but the same method must be observed if more than two divisions are used), and also into three sections in its depth. The number of sections in the comber-board must correspond to the number of sections in the machine. The threading of the machine is done from the rear towards the front, and from the left towards the right. The threading of the comber-board is done in a corres- ponding manner. 300 ends for each section in one division, divided by 4 rows deep each section, making 75 cross-rows. Threading of the Jacquard harness is as follows : R and R" are for the two-lease strings ; S, the successive order of threads ; S", the number of leashes. Hooks and needles correspond with drawing A. White warp-threads indicate section i ; shaded warp-threads, section 2 ; black warp- threads, section 3. The fine lines in Fig. LIX. indicate the leashes for the first 55 row deep of the comber-board; the heavy Hnes indicate the last leash for each section. Fig. LXI. illustrates a fabric designed for - this tie-up. The various small star effects are arranged' on the principle of the 5-leaf satin. i^-i-i-® i^^^lf-® i^^^® i ■ljf®i^^^®^*^¥*^*^#®^^^ ^^^^|f®^^^^®^*^¥*^^^-^* ■^ljf*9^^^^*^^^^|f#l^^^4jf®^4f ®^^^-i^®i-j^*^k*^^^"j|^*^^*^ i^^i® li^ii-® ^i^^^lt » ^^^^ ® ^ Fig. LXI. IX. The Point Tie-up in Three Sections. This method of tying-up Jacquard looms shows the point tie-up applied to the three-section arrangement, on the same principle as the straight-through in paragraph VIII. Fig. LXII. shows the comber-board divided into three distinct sections, marked Fig. LXII. /., //. and ///. For explanation, take a 300 machine ; allow 100 needles and hooks for each section, distributed as follows: Section I., i to 100; Section II., loi to 200; Section III., 201 to 300. Each section contains 200 warp-threads ; and the complete 56 division of three sections, 600 threads. The threading of three sections, illustrated in Fig. LX., is applied to the present tie-up, as follows : ist end, from section I., attached to No. i harness-cord. 2d i( <( II., " lOI (( 3d it (( III., " 201 <( 4th a (< I., '* 2 « 5 th <( (< II., " 102 « 6th (( <( III., " 202 tt 7 th (( « I., 3 1 1 8th <( << 11., 103 (( 9th (( » III., 203 l( X. Combination Tie-up in Two Sections. (" Tie-up Amalgamate.") This tie-up illustrates the point tie-up and the straight-through combined on the two-section system. In Fig. LXIII., a 600 machine is used for illustration ; the Fig. LXIII. comber-board being divided into two parts ; a, b, c, d, for No. i section \ e, f, g, h, for No. 2 section. No. I section requires the use of needles and hooks i to 200 on the straight- through principle, four divisions, taking 800 warp-threads. No. 2 section requires the use of needles and hooks 201 to 600 on the point principle, one division, taking 800 warp-threads. The two sections thus use 1600 warp-threads in one repeat. The threading of the harness is as follows : 1-201, 2-202, 3-203, etc., ending with 200-201. This tie-up, as well as any changes in the arrangement and the number of needles, (but not changed in its principle), is used for double color figures of warps of large design, with a small all-over figure effect (No. i section) for the ground. Fig. LXIV. is executed on this tie-up. Fig. LXIV. XI. The Straight-Through Tie-up in Four Sections. Fig. LXV. shows 384 needles and hooks of the Jacquard machine, threaded in four sections in comber-board, A, (B, C, D. The threading of comber-board is as follows : (ho « >i«< {DO O - ■S e-t^r-t- *- r-^«^«-»r-0D 00 00 00 Fig. LXXV. 58 I St, No. I leash in section i. 2d " 2 " 2. ^d " 1 0 0 4th, " 4 ( ( 4. 5th, " 5 ( ( I. 6th, " 6 1 ( ' ' T 7th, " 7 8th, " 8 < < 4. 9th, " 9 " I. And so on. The threading of the harness is explained below the comber-board, /and indicating the leash-strings ; and warp-threads i, 2, 3, 4, from leashes i, 2, 3, 4, are indicated as threaded. 384 times 4 divisions make 1536 warp-threads. XII Tying-up of Jacquard Looms with Compound Harness attached. Tying-up of Jacquard looms with extra compound harness, consists in applying two separate systems of harness in the loom. The warp-threads, after having passed through the Jacquard harness, are passed through harness in front. Each system of harness performs special duty, although they are both working the same warp. • The Jacquard harness is used for forming the general design on a large scale ; the second harness divides this pattern into detail, (twills, satins, or any other desired weave). The above tie-up is necessary in the manufacture of rich damasks and similar fabrics, where a large number of warp-ends is required, with a correspondingly small number of picks per inch. Suppose a damask fabric to contain 300 ends warp per inch, with only 75 picks per inch; or in the proportion of 4 to i. Now, to employ this principle of making four ends warp equal to one filling, the size of the design would be produced in the fabric, but the richness, and also the fineness, of the face of the fabric would be entirely lost. To prevent this it should be the object of the designer to keep the fine warp-threads entirely on the surface, to interweave the proportion of ends varying between warp and filling (as in example above, four warp-threads) separately. This principle of textures requires the compound harness to be attached ; or, in other words, a machine must be used which is capable of raising not only every alternate thread, but every third, fourth, or eighth thread, if required, for the formation of the body of the cloth. Fig. LXVI. illustrates as plainly as possible the principle of tying-up to do this work, using a 100 Jacquard machine for figuring, comber-board threaded in three divisions, four heddles to each leash, eight compound harnesses. In the tying-up of Jacquard harness four heddles to one leash are generally used, as illustrated at c, in Fig. LXVI. ; each heddle containing one warp-thread. Fig. LXVII. shows the arrangement of these four warp-threads, when using only one heddle to each leash, but in which the mail contains four eyes. This method is less frequently employed. Instead of using a 100 machine, as in Fig. LXVI., 53 A 200 machine (straight-through) will require 800 warp-threads for each division. 300 " " 400 " " 600 " 900 1200 " " ( (( " 1200 " (< It ( (( " 1600 " l( 1 1 ( << " 2400 1 ( << i (( " 3600 " <( < ( < << " 4800 " it (< "A Fig. LXVI. To change the tie-up principle from the straight-through method to the point method, taking a 1200 machine using four heddles per harness-cord, 9600 warp-threads will be required for each division for repeat of pattern. This litde example plainly shows the great advantage of this method of tying-up Jooms for making the finest damasks, etc. To explain the general method of this tie-up, commence with Fig. LXVI., which represents a 100 machine, three divisions, four heddles to one leash, eight compound harnesses. It will not be necessary to explain the threading of the comber-board, as Fig. LXVIT. 60 this is always done on the same plain principles. The four heddles of the first row deep of comber-board emerge below the board at the beginning- of the first division, marked a, a', a", a'". The first row deep in comber-board in the first division, and the last row deep in comber-board in the third division only are shown ; but as these two rows also indicate the first and last rows in the Jacquard machine, and as the principle of a, a', a", a'" , and b, b', b", b'", has to be observed in every one of these 75 rows deep in width of comber-board E' to E" taken, it will explain the tie-up for the entire number. At c, in leash a, four distinct heddles are adjusted ; the same thing is repeated in every one of the eight leashes extended in drawing below the comber-board, giving in return, thus : four heddles and three divisions in a 100 machine = 4 X 3 X 100, or 1200 warp-threads for the entire fabric. Now, following the first heddle downwards on leash I, a, c, marked on drawing, d, (indicated by dotted lines), No. i harness of the compound harness, H, is reached. The cross X on this harness indicates that the warp-thread drawn through mail fastened on heddle, d, must also be drawn through No. i harness ; the next heddle from the same leash will reach No. 2 harness ; and so on until No. 4 harness is taken up, which will finish No. i harness- cord of No. I leash in the first division. The second harness-cord, a\ will use harness 5, 6, 7, 8 ; the third harness-cord, a", will use harness i, 2, 3, 4, over again, as used by a ; the fourth harness-cord, a'", will use harness 5, 6, 7, 8, over again, as used by a'. Fig. LXVIII. Fig. LXIX. Continue In this manner until leash 100 in the first division on harness 5, 6, 7, 8, Is finished. The second and third divisions strictly repeat the first. Fig. LXIX. represents the side elevation for Fig. LXVI. In both of these drawings some of the letters and figures correspond, as follows : harness-cords 61 a, a\ a", a'", in first row deep of comber-board, E, E'.

Leashes i and 4, or a and a'", are not raised. The principle of forming the shed for picking the shuttle will be more particularly explained later on by Figs. LXX. to LXXV. At c, in Fig. LXIX., the beginning of the shed is shown ; also the last woven part of the fabric, c, c\ c", which is indicated as passing around the breast-beam, F. L, L', L", L", indicate leashes i, 2, 3, 4, extending to the Jacquard machine towards neck-cords i, 2, 3, 4. Fig. LXX. represents a warp-thread forming the bottom part of a shed. Mail, Z, and harness. occupy a position similar to that of mail and harness for warp-thread passing through No. I heddle of leash a, and harness i in Fig. LXIX. ^xx.

The Kind of Heddles Required for Compound Harness. The eyes of these heddles are much longer than those of common heddles. They must be sufficiently long to allow the six movements illustrated in Fig. LXX. to LXXV., hence the height of these heddle eyes will influence the height of the shed. Working the Compound Harness by a Separate Machine. For working compound harness a separate small witch-loom is generally used, thus saving, to a great extent, the Jacquard cards. In this manner the ground may be easily altered without changing any cards, it being only necessary to change the small set of cards on the witch-loom controlling one repeat of the body weave for the harness. The number of picks for the harness can also be readily adjusted to one change in the Jacquard figure without disturbing the cards of any consequence. For example : in manufacturing a damask fabric, suppose four harness picks make one change of figure in the Jacquard machine, and it is necessary to reduce these four picks to one change of figure, on account of having to use some heavier filling, or other similar reason ; this alteration can be easily made when using two separate machines. H3 Ntimber of Compound Harness to Use. Fig. LXXVI. The number of harness used is regulated by the weave required for raising, and the weave required for lowering. The number of harness may vary to a large degree, as we may use any suitable weave from the 4-leaf twill up to the i6-leaf satin. As a general rule, for fine damasks we use the 8-leaf satin, requiring 8 harness. Fig. LXXVII. Filling Weave as raised in the upper shed by harness, ■ Risers. n Sinkers.

Gauze fabrics are produced by a separate system of weaves, which have the peculiar characteristic of warp-threads not lying parallel to each other. One kind of this warp is called the " douping warp " or "whip-threads ;" these are twisted around the ground-warp. The ground-threads, as well as the whip-threads, which work together, must be drawn into one dent. Jacquard gauze can be worked in various ways ; for example : One whip-thread against one or more ground-threads. More than one whip-thread against one or more ground-threads. There are two methods of tying-up for gauze fabrics : ist. A tie-up in which the doups are worked by one, two, three or four shafts in front of fhe Jacquard harness. 2d. A tie-up in which the gauze figuring is done all over the fabric, requiring each doup to be arranged for working separately. If the ground-threads and whip-threads are worked from the same Jacquard machine, the latter must be divided into two sections : ist section for the ground-threads with ground heddles ; 2d section for the v/hip-threads with standard heddles. If a fabric contains the gauze in the form of a stripe, arranged one end ground and one end whip, the same number of hooks are required for the ground and whip- threads of each section, and an extra dead harness must be employed ; but if this arrangement of one end ground and one end whip must form figures, then the ground and whip-threads must form the first section, and the whip-threads alone the second section. In this case the second section requires only half as many hooks as the first ; and for the same reason, if we are forming figures with two ground- threads and one whip-thread, the first section will contain three times as many hooks as the second, etc. Very often two whip-threads are used for twisting, in which case they must be drawn together in the doup. If several whip and ground-threads are drawn into one reed they usually .work independently at first on a regular weave ; following this is the gauze weave formed by a certain number of whip-threads raised either on the left or right of the ground-threads contained in the same dent. This movement brings into operation the second section of the machine containing the harness-cords for the standard heddles. The technical terms for these various combinations are : single-thread gauze, double-thread gauze, triple-thread gauze, etc. The tie-up most generally used requires two-thirds of the needles for ground heddles and one-third of the needles for standard heddles ; hence, if using a 200 machine we find: 128 needles and hooks for the ground heddles, and 64 needles and hooks for the standard heddles. [See Fig. LXXXVII., p. 65.] The comber-board is divided into two sections. The rear part (^) is used for the ground, the front part (^) is used for the standard. Threadmg of the Harness. Thread the warp, into the ground heddles in the same manner as a common straight-through tie-up. Then take the first left-hand thread of the warp and draw it through the doup. The next two warp-threads draw above the first one on the 65 66 left-hand side of the same doup. These three warp-threads must be drawn together in one dent. After drawing the first pair in one dent, leave one, two, or more dents empty, according to the fabric. The 4th, 5 th and 6th warp-threads, also each subsequent pair, are threaded the same as the first. Fig. LXXXVIII. Fig. LXXXIX.

These fourteen different movements cover all the possible changes in regular weaving. The movement (7) illustrated in Fig. 8, in addition to forming the regular weave, is also necessary to the formation of the gauze weave. These few explanations clearly show the great variety of effects possible for the designer ; for he can figure with the regular method of weaving, and can also figure gauze weaving to exchange with regular weaving, forming a separate design on the fabric. Modifications of the Single Lift Jacquard Machine. Having thoroughly described the construction and action of the regular Jacquard machine, it now remains to illustrate and explain its modifications. Among the most prominent are : 1st. The Double Lift Single Cylinder Jacquard Machine. 2d. The Double Lift Double Cylinder Jacquard Machine. 3d. The Arrangement of Substituting "Tail-cords" in place of the Hooks, etc. I. Double Lift Single Cylinder Jacquard Machine. The principle of this machine consists in raising the warp-threads any number of times in succession without allowing the shed to close, thus performing the work in nearly half the time, and with less wear and tear on the warp. Fig. XCVI. represents the sectional cut of one row across all the griffe-bars. The machine selected for the illustration is of the 1 2-row type. Jacquard machines of this description have two hooks to one needle ; therefore in the drawing twenty- 68 Fig. XCVr. (» y7 ' » h 111) 111 four hooks are represented. Two griffes are provided, each working every alternate hook. In Fig, XCVI, the sectional cut of both griffes is shown, and in Fig. XCVII. the top view of both griffes ; the first set is represented shaded, the second black. The former requires hooks Nos. i, 3, 5, 7, 9, 1 1, 13, 15, 17, 19, 21, 23, and the lattter Nos. •2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24. This arrangement permits either hook to be lifted separately by the griffes, and a • corresponding elevation of the leash. As these griffes work in opposition, one de- scends while the other ascends ; this motion prevents the leash from dropping the entire length of the cords, since the ascending griffe catches it at half distance as the two griffes pass each other. In this operation the shed is never entirely closed, and a corresponding gain in speed is attained. It will thus be seen that the "double lift" single cylinder has great advantages over the ordinary machine. Of course, the warp-thread must make its complete journeys up and down when called for by the design ; but when once up, it need not be brought down until Fig. XCVII. absolutely required by the pattern. The warp is thus subjected to less friction in working, and it is possible to use yarns with less twist and obtain good results. The advantages arising from not closing the shed may be seen in the following example of a warp-thread working on an 8-leaf satin, in which seven picks are up in succession. By the single lift machine this warp-thread must travel seven times up and seven times down, thus closing the shed absolutely seven times, with a corresponding wear and tear. The double lift single cylinder arrangement does not require the warp- thread to make these seven complete journeys to the "race-board" of the lay, but instead it makes seven half trips. The saving may be shown by the following analysis : Single lift machine, warp-thread, seven picks up in succession, in 8-leaf satin (warp-face) requiring fourteen complete movements. Double lift single cylinder machine requiring for the same effect : Up the first time, = one complete movement. Six times down, ) , ,^ . 1 ^ ^. . y half movements, = six complete movements. bix times up, j Down the last time, = one complete movement. Or eight complete movements. Showing the utility of the two machines to be to each other as 8 to 14, or 4 to 7. 69 Fig. XCVIII. illustrates the complete double lift single cylinder Jacquard machine, as built by W. P. Uhlinger, Philadelphia. In this drawing both griffes are distinctly visible ; also their mode of operation by means of the double- acting lever. This machine has the set of hooks for each griffe-bar pro- tected by a plate of sheet iron, thus steadying the hooks in their motion, and enablino- smaller crooks to be used for the latter. Fig. IC. represents a double lift single cylinder Jacquard machine as built by Thomas Halton, Phila- delphia, attached to a regular broad loom, (Knowles or Crompton), and tied-up for upholstery work. The griffe-bars in this Jacquard machine are constructed of such height that when lifted they never rise above the crooks of the hooks, which are thrown out of operation by the descent of the other griffe.

Fig. CII., hooks 2 and 4, etc., raised, = i and 3, etc., at rest. II. Double Lift Double Cylinder Jacquard Machine. The principle of this machine consists in the combination of two separate Jacquard machines. Two hooks (one of each machine) are connected to one leash of the Jacquard harness, and as each machine is operated alternately, a high Fig. ic. Speed is attained, which is the purpose of the machine. For example: 140 picks per minute (speed of loom) only requires 70 picks per minute from each part of the double lift double cylinder. In Fig. cm. this is clearly illustrated. It shows two 12-row machines (^and F) combined, thus giving 24 griffe-bars for the complete double machine, as the griffes work within each other. As explained for double lift single cylinder, every alternate bar is connected with a separate griffe, and these two griffes are worked alternately on the same double lever arrangement. O to /'and O' to P\ represent the two needle-boards ; Pto R and P' to R\ represent the two corresponding needle-boxes. 70 These double lift double cylinder Jacquard machines are mosdy used in the manufacture of turkey-red goods and similar table-cover fabrics, using tie-ups similar to the one illustrated below, which is a combinadon of the straight-through and point tie-up, which may be alluded to once more by way of explanation in this particular case. The illustration represents a double lift double cylinder machine containing two 600 machines, which equals an ordinary 600 machine for the tie-up. leashes i to 400 from each part of the double machine. Leashes i, 12, and (heavy lines) only are illustrated in drawing. The borders are constructed on the point tie-up, and require leashes 401 to 604 from each part of the double machine. The first and last leash only are illustrated. The margins between border and selvedge are worked by leashes 605 to 612. Centre and border are 12 rows deep, arranged in the comber-board; the margin 8 rows deep, on account of working it (as is generally done) on an 8-leaf 71 satin. One complete row in machine, (both parts), as well as in the cotnber-board, (illustrated on each side in drawing), is left for the selvedge. Fig. CIV. represents this machine (built by Thomas Halton, Philadelphia,) attached to a Clipper loom. In this drawing both sets of cards (one' to contain the even numbers, and the other the uneven numbers) are clearly visi- ble, and also the double lever arrange- ment for working every cylinder alter- nately. As the cylinders run at only half speed, the wear on the cards is reduced to a minimum. III. The Substitution of Tail-cords for Hooks. Jacquard machines having this con- struction are generally employed in the manufacture of ingrain carpets. Fig. CV. represents the sectional cut of one row of needles across the machine ; also the necessary boards for I I. Fia. CV. Fig. civ, guiding and operating the tail-cords. This machine consists of two divisions' (I. and II.,) which are worked alter- nately for the common 2-ply ingrain carpet, A, represents the top board, ta which the tail -cords are fastened around a wire by knot shown below the boards. Each board is 6^^ by ^ inches, with a distance of i inches between them.

C shows the hanger, which is attached (movable) to the top of the machine. [See E, in Fig. CV.] t. ) 1>. 1 ^- Fig. CVI. Tying-up of Jacquard Harness for Two-ply Ingrain Carpets. With a General Description of the Working of the Loom and Construction of the Fabric. Two-ply Ingrain Carpet is an article composed of two fabrics, produced on the reg lar double-cloth system. These two fabrics are arranged in the loom to form figures by a simple exchanging of positions. A great variety of colors may be put into each of these separate fabrics, (ground and figure), and the most elaborate designs may be used. On every part of the carpet where these two fabrics do not exchange, each works on the plain weave. The exchanging of these two fabrics binds both into one, thus forming the ingrain carpet. In the manufacture of this carpet four sets of warp-threads, and also four sets of filling-threads are generally employed ; but, if occasionally more or less should be used, in warp or in filling, or in both, in the same fabric, the principle of exchanging is still observed. If employing four sets in warp and ,* («^.u,«u..m filling, two sets of each are used for , ^''^^^''^^ ^ H^ry^ , swas«a^ sw^i .ss.a forming the figure, the other two sets OA/ib<8)^^ forming the ground, each of the figure-threads having as its mate one of the ground-threads. These threads 5toj^art. ^ ltd. .. ^ \^ are so arranged that when a figure- '^jroiva* q .. nr^iu ^ wuvt, thread appears upon the face of the fig. cvii. fabric its mate appears upon the back, and when the figure-thread appears upon the back the corresponding ground-thread appears upon the face. To give a clearer understanding of the foregoing, a sectional cut of an Ingrain carpet fabric is given in Fig. CVII. 73 Suppose the filling-threads for the figure to be : Red, indicated by heavy shaded circles; picks 2, 6, 10, 14, 18, 22, 26, 30. Black, indicated by full black circles ; picks 4, 8, 12, 16, 20, 24, 28, 32. And the filling-threads for the ground to be : White, indicated by empty circles; picks i, 5, 9, 13, 17, 21, 25, 29. Olive, indicated by light shaded circles ; picks 3, 7, 11, 15, 19, 23, 27, 31. Fig. CVIII. A careful examination of the drawing shows that the white threads mate with the red, and the black threads with the olive, so that when one of these colors shows upon the face the mating color will show upon the back, and vice versa. As a general rule, these warp-threads are of the same color as the weft-threads ; hence, every filling pick^ appearing either on face or back, is bound by a warp- I 74 thread of the same color. The sectional cut represents four distinct effects with 32 picks, thus allowing 8 picks for the illustration of each part. I St effect, picks i to 8, is ground up (white and olive). 2d 9 to 16, is figure up (red and black). 3d " "17 to 24, is ist effect in shot about'' (red and olive up). 4th " " 25 to 32, is 2d " " " (white and black up). Two methods of tying-up Jacquard harness are in use : 1st, the "straight-through" principle, (known to the trade as "cross-point"). 2d, the "point" method, (known to the trade as "centre-tie"). I.

The four journals are clearly illustrated by Fig. ex. (each journal carrying its own set of threads). Fig. CIX. The first thread in the loom (left side) will be found on the first journal. " second " " " " " " third " " third " " " " " " second " " fourth " " " " " fourth " This arrangement of threads, 1,3, 2, 4, is repeated throughout the fabric. For an example, a carpet is shown termed "extra fine," executed on 26 "designs," VtOUft I Z 3 t i (, 1 8 10 M 12 1* i5 !(> n IB ") 20 j(ou,rTuitr r a a K V It 1 I* •l' f J' V I' i£ i V Catori <^ A i J i •« i .s ;i )e ■i 4 k ■i •i i 0 ll i m. •i i ■H i Fig. ex. requiring 26 X 8. or 208 small squares for warp on the designing paper. Ingrain carpets are generally woven one yard wide, having in this width two repeats or divisions ; hence the number of harness-cords for the present example is as follows : 26 X 8 = 208 X 2, for ground and figure; 416 X 2, for two divisions, = 832 harness-cords (or 416 leashes) required for tying-up. 75 3i. Fig. CXI. illustrates the adjustment of heddle (mail) and lingo through the journal, y, by means of the heavy knot at d. This knot must be large enough not to pass through the hole of the journal.

Connecting cord of heddle to harness-cord, a to 5=6 inches. ^ This drawing will explain the principle of raising the warp either by means of the harness-board, (arrow i), or by means of the knot through raising the journal, (arrow 2). If raised by means of the harness-cord, the connecting heddle slides upwards in the hole pro- vided for it in the journal; or the journal takes the place of a common comber-board ; but if the journal be used for raising, the knot, d, will rise with it, carrying the heddle the same as before, the harness-cords becoming slack by this movement. In Fig. CVIII., p. 73, the journals are arranged as follows : I St journal, 2d - j ^ ' I Olive, 3d Red, 2d Black, 4th In the same drawing are also represented the first eight heddles (in both divisions), as connected with harness-cords i, 2, 3, 4, 5, 6, 7, 8; also the last four heddles of the rear journal (fourth) connected with their corresponding cords, 404, 408, 412, 416. The first row (i to 8) illustrates the principle of tying-up the harness and the leasing of the heddles ; whereas the four heddles in the rear (404' 4^8, 4^2, and 416) show the practical commencement of the tie-up z. e., four neck-cords in succession to four heddles of the journal. J. represents bottom-board in the machine where the neck-cords for the ground harness-cords pass through. (B, the bottom-board in the machine where the neck- cords for the figure harness-cords pass through. In Fig. CIX., showing the lifter-boards, A is also used for the ground, and B for the figure ; 26 rows of the machine are shown for explaining the tie-up for a texture known as "extra fine," or equal to 832 heddles in the width of loom (one yard) . Jacquard machines for two-ply ingrain carpets are usually constructed with 34 rows, and 335^ of these are used. 33^ rows have 331^ x 8, or 268 needles, which carry 1072 threads, the number actually used in what is termed a full "extra super." Should only 30 of these be used, having 30 X 8, or 240 needles, and carrying 960 3d 4th for ground, {White, ist set of threads. ^ 'I Oh for figure, For repeat, — 238 times over.

It frequendy happens that we find slio-ht variations in the number of threads used in the various grades of carpet named. The pattern may require such a change, or economy in production may induce the maker to use a smaller number ; or, as is done in a few instances, a manufacturer may always make his " extra super " on 32 rows ; but all such changes are done by a corres A.

Fig. CIX., p. 74, illustrates the full 34 rows, and indicates 26 rows used for illustration of tie-up (4 rows ^ empty on each side). In power-looms the raising of the different journals is gen- erally accomplished by an arangement of cams, but in hand-looms it is done by the lifter-boards. In Fig. CIX. the four large holes on each side are made for this purpose, and the wires for raising the journals are shown by heavy lines in tie-up in Fig. CVIII., p. 73. Fig. CXII. represents the process of Hfting the journals, as follows : First pick raises lifter- board A, journal 4 ; second pick raises lifter-board B, journal i ; third pick raises lifter-board A, journal 3 ; fourth pick raises lifter-board B, journal 2. The two positions of the four "tails" in these four picks are illustrated as fol- lows : Fig. CXIII., hole in cylinder ; CXIV., no hole in Fig. CXV. 77 cylinder. The black spots represent the knots, either as caught in the slot or passing- free in the hole. Looms tied-up on the foregoing principles have but one operation of the Jacquard -needles for every two picks of the loom, there being an operation of the ground and figure lifter-boards in succession between the operations of the Jacquard needles. Each Jacquard needle controls two tails, one connected with the warp for the figure, (red and black in our example), and the other to the warp for the ground, (olive and white in our example). The drawing of the lifter-boards shows the slots for catching the tails in opposite directions from each other ; hence, when the figuring tail of the needle is adjusted so as to be lifted by the figure lifter-board, the grbund- tail will not be acted on by the ground lifter-board when it rises. To give a clear understanding of the foregoing explanations, a detailed state- ment of the operations of the loom necessary in weaving a piece of the fabric is shown in sectional cut Fig. CVII., as follows : Pick.

Fig. CXV., p. 76, illustrates a fabric design for an ingrain carpet, straight- through tie-up, a and d forming one repeat, (or one division), equal to one-half yard. 78 II. The Point Tie-up for Ingrain Carpets. This method of tying-up is based upon the straight-through tie-up principle, arranged as follows: The design in the fabric repeats from its centre equally towards each selvedge. centre. Figs. CXVI. and CXVIL illustrate two fabric designs, a to b, \,^^^^ the width of the fabric or one yard on the loom ; c is the centre \tll. Idgel Fig. CXVT. or point of the design ; b to d\% the repeat of a to c, where the widths are sewed together. Fig. CVIII., p. 73, shows the first and last rows, also the two centre rows of the journals threaded to the neck-cords (tail-cords) of the machine. Each cord is numbered to correspond, a, b, c, d, represent the cords for lifting the journals, on the same principle as in the straight- through tie-up. In power-looms this is done by a cam arrangement. Fig. CXIX., p. 80, is designed to give a thorough understanding of the adjustment of harness-cords to heddles, as well as the leasing of the latter.

The beauty of an ingrain carpet consists in its color combination. In hand- looms the common batten is used in connection widi a shuttle which is somewhat curved, a form most suitable to being thrown by the hand. The batten naturally falls towards the weaver by its own gravity, being usually worked a little out of a vertical line for that purpose. In this method the shed forms its own shuttle-race, or bed upon which the shutde slides. When two or more shutdes are used, Fig. CXX. they are laid on the woven piece of carpet before the weaver, and he selects them as required. If a solid shuttle-race is connected to the batten, the warp-threads are pressed down upon it and the shuttle slides upon the ridge of the warp-threads. In this case the "fly-shuttle" is used, and also the "drop-box;" the latter being operated by some of the reserve nee- dles of the Jacquard machine. , Fig. CXX. shows a shuttle-box 1 1 .. L vXI. 81 mechanism for carpet hand-looms. As already stated, the four journals in power- looms are lifted by cams or similar contrivance's. In Fig. CXXI, (representing the Crompton carpet loom) this cam arrangement is clearly visible ; the cams are situated above the journals, the latter being lifted by means of the journal rods from •above. The loom carries four shuttle-boxes at each end of the lathe ; any one of the series at either end can be brought into line with the shuttle-race at any pick. In some looms the journals are also lifted from below, as shown in Fig. CXXI I, representing the " Knowles " carpet loom. The Knowles Loom Works build this loom with journal cams outside the loom, easy of access, and by a simple arrangement of levers the journals may all be brought to the same level at any time. This loom is sometimes built with journals operated by chain motion so either journal can be called at will. This is very convenient in getting out new combinations in weaving. The box mechanism (four boxes on each side of the lathe) is positive, and controlled by a chain on the same shaft as the journals, and may be used with the chain alone, or 82 with the chain in combination with the cards. The motion can be run forward or reversed at will, and any box called as desired. Before closing this article, it is necessary to mention the method of working the loom built with a stationary "shuttle-raceway" and an independent "comb," the latter having a reciprocating movement for beating up the filling, and a rising and falling motion for bringing the comb up into, and taking it out of the warp ; it has also yielding racks and filling forks, and a cam so timed for operating the forks, that the latter will seize the filling and carry it forward in front of the range of the said comb. Fig. CXXIII. illustrates the side view of the comb and its lay ; also the parts necessary to be shown for working the same: the independent lay; d, the comb ; c, the reed ; a, its lathe ; the shuttle-race ; c, the breast beam of loom ; oval ring, d, e, represents the motion of the comb in beating up the filling ; e, r, upper shed of the warp ; e, t, lower shed of the warp ; x, the shed ; stud fixed to the loom framing ; h, i to i, k, toggle connection of lay to stud, h ; z, m, to m, /, crank connected at z to the toggles ; /, crank shaft ; o, lever for raising and lower- ing the lay, k ; n, its fulcrum ; s, grooved cam for working lever, /, o. Fig. CXXIII. Fig. CXXIV. The vibratory movement of the comb-lay for beating up the filling is produced •by the action of the cranks upon the toggle connections ; and the upward and downward movement of the lay, to produce the entrance of the comb into the warp and its withdrawal therefrom, is produced by the action of the lever upon the grooved cam. The comb, d, is constructed of teeth, which are secured together by a bolt passing through them, and which have their bases of dovetail form to enable them to be secured between a dovetail lip, on the lay, and a dovetail clamping plate, secured to the lay by bolts. Fig. CXXIV. illustrates the method of lifting the journals from below. The journals, of which there are four, are arranged to work in upright fixed guides on the loom framing, d, e, /, g, and are operated by treadles, which are arranged in pairs below, each journal being connected with one pair of treadles by two rods at 83 its opposite ends. These treadles are operated by cams for each pair of treadles and each journal. Fig. CXXV represents the top view of the "fixed guides" containing ^ the journals. This loom is provided with ten shuttle boxes^ (seven for I L^ ^ ^ the revolver, three upright), for each side, and built by the Furbush ^® ^ ^ Machine Company, being a combination of their older carpet loom 1 known as the " Murkland," and the " Duckworth Carpet Loom " cs) .1. Fig. CXXV. Rise and Drop Shed Jacquard Machine. Fig. CXXVI represents a RISE and DROP shed Jacquard Machine as built by the Geo. W. Stafford Manufacturing Company, Providence, in which the bottom plate descends as the griffe rises, thus carrying down all threads that are not raised by the griffe, to form the bottom of the shed. It will be seen that the griffe has to lift but half as far as on the ordinary straight lift machine, for the threads that descend form an approximate half of the shed, and, also, acting as a counterbalance for those con- trolled by the griffe, make an easy, smooth working machine. Fig. CXXVI. The special feature is the manner in which the griffe and bottom plate are oper- ated, for " rise and drop " shed Jacquard machines have been built before this, but have been so constructed that the bottom plate was coming up at the same time that the hooks coming down with the griffe came in contact with it, thus striking a blow which caused rebounding of the harness and allowed no increase of speed. In this newer form of machine a cam is employed which gives a dwell to the bottom plate while the griffe is continued in action, so that the griffe starts on the upward movement before the bottom plate begins to descend, and on the return motion the bottom plate comes to rest before the hooks coming down with the griffe drop upon it, thus avoiding the shock existing in the older form, and enabling increased speed. Another feature contained in this machine is the forming of an angular shed which is of great benefit in many cases. APPKNDIX Preparing and Stamping of Jacquard Cards. Preparing. The Jacquard card consists of a strong, durable pasteboard cut to the exact size of the cylinder. For cutting or preparing the cards to the required size, a table is used with the different sizes of cards indicated on its surface. A sharp steel blade is adjusted to the side of the table. A heavy knife of sufficient length, and containing a second steel blade, is secured to a projecting bolt on the rear end of the table, allowing enough play for the knife to be easily raised and lowered. The blade of the knife works close against the blade fastened to the table ; and when pressed down both blades rest close together. On the front side of the table is a long groove in which is a guide, fastened by a bolt and nut. This guide can be set to suit any of the marks on the table, thus regu- lating the size of the cards to be cut. Two measures (the length and the width) are required to be cut for each set of cards : I St. The sheets of pasteboard are required to be trimmed one way in sufficient number for the length of the cards. 2d. Each trinimed sheet is afterwards separated in strips of the required width. Card Stamping. The oldest method for stamping cards-, now only occasionally used, consists of two perforated steel plates, between which the blank cards are placed, and the required holes stamped by hand by means of punches. It will easily be seen that this method is not up to the present advanced times, hence various machines have been introduced for arranging the punches. Among those most generally used are : I. — DoBBY Card Punching Machines. II. — Piano Card Stamping Machines. III. — Repeating Machines. 85 Fig. I. 8d I. Dobby Card Punching Machines. These machines, illustrated by Fig. i., (W. P. Uhlinger, builder), are used for stamping cards for the smaller Jacquard machines, technically termed " Dobbies." They are of very compact build, and operated by belt-power. The whole card is punched at one revolution or stroke. The rack on top of the machine holds the design. The punches for peg-holes and lace-holes are immovable, while the key punches act independently, at the will of the operator. Jacquard cards for tbese machines are generally composed of the strongest pasteboard, and require a very strongly constructed machine. II. Piano Card Stamping Machines. These are operated in two ways, by the belt or foot-power. There are two kinds of each: "French index" and "American index." Figs. 2 to II are drawn to one-half the actual size of the "Uhlinger Card Stamping Machine." Figs. 13, 16, 17, 18, 19 are drawn to one-quarter the actual size of the " Royle Card Stamping Machine." Figs. 2 and 13 {E, F, G, H,) represent the top view of the head (cover taken off), the twelve holes for holding the punches for one row, also the large hole for holding the peg, P. Each punch works vertically, and is guided by a key for stamping the hole. Fig. 14 illustrates the punch (actual size) as used in the "Royle" machine: a to d = ^ inch ; d to c= 2^ inches ; ^ inch diameter of punch, ^ to c. Fig. 15 illustrates a corresponding key: diameter of key -3^- inch, ^ to e; diameter of head, inch, a to b ; ^ is the hole for inserting the pin which holds the spring. The length of the keys vary from i^ to 2^^ inches, according to the position they occupy in the machine. The punch and key of the Uhlinger machine are shown (one-half of actual size) in Figs. 4 and 5. A and (S, in Figs. 2 and 13, represent the piston for guiding the head in its vertical motion. Fig. 3 represents the front view of the liead. The numbers and letters indicating the different parts correspond with Fig. 2. The principle of construction and action of the heads in both kinds of machine are similar. Each key is provided with a fine spiral spring, which, after every action of the key, returns it to its original position. The key for the peg-hole is controlled by the larger spring, S, D, in Figs. 2 and 13. The arrows in these two drawings indicate the direction taken by the keys when under pressure. When cutting cards eight rows deep, the thumb of the right hand works the key for the peg-hole ; the eig^ht keys in the rear of the machine (which are the ones to be used) are worked by the four fingers of each hand. When cutting cards twelve rows deep, the eight keys in the rear are operated by the eight fingers in the same manner; but the thumb of the right hand operates 88 keys marked i and 2, and the thumb of the left hand operates keys marked 1 1 and 12. During- the cutting operation the fingers should not be removed from the keys ; they should always be in readiness to press the required key into action, as this is the only way to become expert. The eye of the card stamper must rest uninterruptedly on his design ; and the keys are called at will by the fingers, without the eye leaving the design, to find out where a certain key or finger is situated at the time. Fig. 4 shows relative positions of punch, S, and key, B, when ready for stamping a hole. Fig. 5 shows the relative positions of punch and key when no hole is required. O represents the Jacquard card as resting in the slot of the lower head. II. in Fig. 3, marked X to Z, shows a full width view of this card. The space (Z), in Figs. 4 and 5 permits the spring to be inserted regulating the key. A, B, C, solid parts of the upper head, (I., in Fig. 3). F, G, K, L, solid parts of the lower head, (II., in Fig. 3). The cards are passed into and through the stationary part of the head at X, Z, and are attached to a "carriage" in the rear of the punch head. Two methods are employed for moving the carriage : ist. By a "skipper" at its rear fastened to the carriage, which moves in a rack of pins secured to the cutting table. This method of construction is used by the Uhlinger machine. Figs. 6 and 7 are front and side views of this mechanism. Figs. 8 and 9, the top view and sectional cut of the rack. 2d. The rack is fastened to the carriage, and the skipper to the table, thus reversing the first method. [See Fig. 19, top view.] This method of construction is employed in the Royle machine. The distance of the pins in the racks in both systems of construction (American and French) corresponds to the distance of the rows in the card. The racks are generally constructed for 600, 900, and 1200 Jacquard machines. Of these three sizes the 1200 is the most advantageous, as cards can be cut for any smaller size machine. The rack of a 900 machine (French index) contains 88 pins, while that of a 1200 machine (French index) contains 114 pins. Fig. 10 illustrates the "catch" for holding the cards in the Uhlinger machine. This is fastened to the carriage when pressed by the hand on top in the direction of arrow, S; this catch will compress spring, D, in the direction of arrow, S', thus opening the "blade," Q (front view shown by Fig. 11), in the direction of arrow, S" , thus allowing the card to be inserted and held, securely fastened to the carriage. Fig. 18 illustrates the side view of the carriage and its catch for holding the lacquard card as used in the Royle machine. Arrow, S, indicates the pressure of the operator's hand on lever, B, when the card is inserted. This lever presses by means of presser, D, in the direction of arrow, S', on the double-acting lever, E, 90 at c. This lever moving around its fulcrum, e, will lift catch, F, in the direction of arrow, S", thus allowing the card to be inserted. Spring, G, fastened to main part of carriage, A, by means of screw, a, secures the card to the catch. C, C', are the carriage wheels, of which there are four. Fig. 19 represents the top view of Fig. 18, and is designed to show the arrangement of levers, wheels, and catches of the complete rack as used fgr a 900 machine. The letters indicating the different parts correspond with the ones used in Fig. 18. Fig. 16 shows top view and ground plan, and Fig. 17 the front elevation of the "card-guide," as constructed on the Royle machine. It is universal and self- adjusting to any width of cards from ^ to 3}^ inches ; both guide-plates, C and D, are caused to move equally toward or away from the peg-punch, thus accurately centering the peg-hole in all cards. Letters A, (B, P, and numbers I to 12, correspond to those used in Fig. 13. E, F, H, K, are the three levers moving around pin,' G, (the latter in even line with the centre of the peg-hole, P). These levers are held by screw, L, in any required position. Spring, S, holds lever, F, H, against pin, T, which in turn is fastened to the same plate as screw, L. Fig. 16 indicates the card-guide set for a 12-row card. Let us sup- pose it necessary to cut an 8-row card. Loosen screw, L, and spring, S, will instantly contract until each side of the guide has moved the re- quired distance (two holes and two spaces between holes) towards the centre. Much valuable time is saved by the use of this guide, as it instandy adjusts itself to any width of card, and at the same time centralizes each card passed through the machine. In factories where broken cards require to be constantly renewed, the value of this guide is especially noticeable, there being no material interrupdon of the regular work of the operator, who can replace the damaged card at the moment wanted. Letters indicating the different parts in Fig. 17, correspond to those used in Fig. 16. As mentioned before, the pistons, A and (B, of the cutting head are con- nected below the table to the cutting levers, and by a simple combination of levers. 91 A. B. the cutting pedal is brought in direct relation to the cutting lever ; all of which are illustrated in the perspective view of the Royle machine in Fig. 20, and the Uhlinger machine in Fig. 12. The working of the cutting pedal is very simple. Pressing the pedal, situated at the right, causes the punch head to descend, and the punch penetrates the card. Transferring the pressure from the right to the left pedal raises the punch-head to its former position, (punches above card), ready for a repetition of these movements. The "skip" arrangement allows the carriage to advance the distance from one pin to the other in the card-rack, thus placing the card in proper position under the punches. At the proper height above the punch- head is the reading-board, on which the guide-rules are moved across the design by screws, which are connected by gearing and operated by means of the hand-wheel or crank shown on the lower side of the board. As drawing-pins or thumb-tacks are generally used as fastenings for the design, the reading-board is made of soft wood, and its trimmings are made of hard wood. 21 illustrates the Uhlinger Card Stamping Machine operated by belt-power. Being the same in principle as the foot- power machine, it is only necessary to state that instead of work- ing the machine by means of the cutting pedals, it is done automatically by simply touching any of the keys that operate the punches ; thus the machine makes one stroke and punches the required holes.

Before commencing this work a clear conception of the tie-up and leasing of the heddles is required. The holes in the cards for the needles to penetrate, or the spots in cards where no hole is to be stamped, must be arranged in an uninterrupted chain from one row to the other, until all the rows are taken up. As previously mentioned, the method observed in tying-up the loom is the guide for stamping the cards. The number of ends re- A B ■PBBMBPMBMBnHMBiniMMBPPMnnnPBPpnpgnPPMMM » h-nMM*MPMM««P«*«W3MJiMMni««MPi :pn*t Fig. 23. D quired in a certain design may repeat only once in the number of hooks and needles employed in the Jacquard machine ; or they may repeat two, three, or more times. Fig. 23 illustrates a design upon 40 warp-threads. Fig. 22 shows the corre- 92 spending card, (French index), one-fourdi of its actual size, for the first pick. In a 200 machine this design will repeat itself five times. The lace-holes and the peg- holes are blank. The reserve row (26th) is shaded, and the design as cut in card is indicated by black dots. This cut also shows the direction of reading each row to correspond with the numbering for the punch-heads, in Figs. 2, 3, 13, and card-guide in Fig. 16. The numbers i to 40, 41 to 80, 81 to 120, 121 to 160, 161 to 200, indicate the direction of stamping the design, as well- as the five repeats to form the complete card. In this connection it will be of great advantage to examine Fig. XXIX., p. 28, under the head of the Jacquard Machine and its Tie-ups. Fig. 24 illustrates a Jacquard card (American index) stamped for ingrain carpets, one-half of actual size. This card illustrates the stamping for two textures, i' to 208' being for "extra fine." The 26 rows needed are shown full black, and marked to correspond. The peg-holes and lace-holes are left blank. In the other texture, or what is termed extra super" ingrain carpet, the addidonal rows are repre- sented by the shaded holes at the ends of the cards. Arrow, S, indicates the direction for commencing to read off each row. III. Repeating Jacquard Pattern Cards by the Positive Action Repeater. If several sets of cards of one design are required for starting a corresponding number of looms, and the first set has been produced by the " piano machine " exact duplicates can easily be obtained at small cost to the manufacturer by the " Repeating Machine." This machine is built by Messrs. John Royle & Sons, Paterson, N. J., and is illustrated by Fig. 25 in a perspective view. Fig. 26, p. 94, represents a side elevation of the machine with its throat-piece through which the cards that are to be cut pass, the carriage on which the throat-piece is supported, and the mechanism employed for imparting a rising and falling motion to the carriage. Fig. 27, p. 95, is a vertical longitudinal section of the upper portion of the machine. Fig. 28, p. 95, gives a perspective view in detail of portions of a selecting-needle and key-wire and a lever connecting them. • Fig. 29, p. 95, gives a view in detail of the mechanism employed to turn the pattern cylinder. The cards to be duplicated {N, N, Fig. 26, p. 94.) are arranged upon the card race-arms {M, M, Fig. 26,) in the same manner as upon • •• • • ••• • • • • • ••• • • • • • • E. 0 0 I • • • • • • • • • • • • • • • e ® @ ® ® ^ ^ ® • 9 ® @ @ @ ® # & e @ ^ 0 n 0 0 c. 5. Fig. 24. 93 loom. The uncut or blank cards, having been previously laced together, {E, E, Fig. 26), are piled in the rear at the base of the column, and thence passed forward through the machine, and delivered finished in front. The perforating of the cards is performed by a vertically reciprocating die, (Z), Fig. 26), and a set of punches {Q Fig. 26,) carried in a fixed punch-head, and capable of being pushed upward when such movement is not prevented. The cards commonly used are of a size to receive 600 holes, and hence that number of punches are required. The cards {E) to be cut are drawn over a "reel" or "idler" {E, Fig. 26,) at the back of the machine, and thence pass through openings in the base frame to the front of the machine, and over a square cylinder having a step-by-step rotary motion. Fig. 25. By each quarter turn of this cylinder, the chain of cards is drawn forward sufficiently to bring a new card in the die. By the rising movement of the die (carriage), which takes place as soon as the intermittent feed of the cards has ceased, the card in the throat of the machine is carried up against the lower ends of the punches, and is cut or perforated by all such punches as have their upward movement prevented by the keys; while such punches as are not arrested by the keys are carried upward, and do not puncture the card. The pieces of card cut off fall through a throat or opening in the carriage [E, Fig. 27,) into the hollow base frame, [A, Fig. 27), and can be taken out at the door, [A, Fig. 26). 94 It will therefore be apparent that the variations in the cards are produced simply by holding down different punches in successive punching operations. This is regulated by the original set of cards, (A^ Fig. 26), which are passed over the pattern cylinder [O, Fig, 26). The latter has also a step-by-step rotary motion similar to the cylinder first described. Its four faces are covered with holes the same distances apart as the perforations in the pattern cards. This pattern cylinder is mounted in bearings in a carriage on the top of the machine, and is reciprocated back and forth be .ween the successive rotary movements of the feed and pattern cylinders. Fig. 26. In the upper part of the machine are arranged what are termed selecting needles, (C, Fig. 27), which consist of wires arranged in horizontal rows, with their ends opposite to the pattern cylinder, and which are the same distance apart as the holes in the cylinder, so that if the cylinder were moved up by the carriage against the ends of the needles, the latter would enter the holes in the cylinder, and would not be moved longitudinally. There are the same number of selecting needles as punches in the machine — six hundred. When, however, a perforated pattern card is on the cylinder, and it is moved against the ends of the selecting needles, such needles as are opposite the perforations of the cards will enter them, and will not be moved, while such needles as are opposite the blank spaces of the cards will be moved longitudinally. [See Fig. 27 for illustration.] At the reverse movement of the 95 carriage, an "evener," which is secured to it at the end opposite the pattern cylinder, strikes against the ends of all the needles so moved and pushes them back to thdt original position. Above each of the punches before described is a horizontal sliding key {B, Fig. 27,) attached to a horizontal key-wire {D\ Fig. 27), and the 600 key- wires are arranged in horizontal rows below the selecting needles, and are each connected by a lever {B, Fig. 27.) with the corresponding selecting needle , , ■ , , Fk;. 27. Consequently, a longitil(iinal motion of any selecting needle will move the key-wire with which it is connected in a, re verse direction. Fig. 28 gives a clear demonstration of "the connection of a selecting needle, to the key-wire, / by means of the lever, e, movablp around the fixed pin, d. Each key {D, Fig. 27,) consists of a cylindrical plug of metal, which, projecting over a punch, forms an abutment to keep that punch from rising, but if withdrawn, allows the punch to rise without resistance. A step arrangement of the punches and keys is adopted ; that is,; the upper ends of the outer rows of punches are highest and the punches in the several rows decrdase. in height till the inner row is reached, where the punches are the lowest. ' Hence, the keys of the upper rows, which correspond to the outer rows of punches, are carried over the inner rows of punches and terminate over the punches in the outer rows. jIg 29. 96 Normally, all the keys are above the punches, and all would punch when the die ascends, but when a pattern card is carried by the pattern cylinder against the ends of the selecting needles, certain needles are moved and produce a reverse movement of the corresponding key-wires, and draws certain keys out of reach of their punches ; no resistance being offered to the upward movement of such punches, they do not perforate the cards. The carriage on which the pattern cylinder is carried being mounted directly on the top of the machine, can be readily lifted off to afford access to the parts below, and it is provided with a movable hood, which may be lifted to inspect the selecting needles. The keys and key-wires are arranged farther apart vertically than the selecting needles, thus enabling larger keys and heavier and stronger key bearings to be used, and avoiding any liability of the punches striking the keys in the tier next above when those of their own tier are withdrawn. Instead of applying a separate spring to each punch to move it downward or return it as the die recedes, a positively operated returning plate is used, which moves down as the die recedes and acts on collars on the punches, [sqg d, Fig. 27], and forces all the punches down. This is very important, for if any of the punches should fail to descend, the movement of their keys would be prevented, and thereby the machine would fail to properly repeat. The bearings of the pattern cylinder are so constructed that the cylinder can be instantly changed to allow either a 400 or a 600-hole cylinder to be used, so that the bearings can be adjusted to adapt them for either size cylinder. The bearings of the feed cylinder, whereby the chain of cards to be cut is moved, are constructed and supported so as to enable them to be readily adjusted to suit slight variations in the tightness with' which the cards are laced, or in a greater degree to suit large or small cards, and the mechanism whereby the cylinder is operated is capable of ready adjustment for the same purpose. It is well known that the punching of a great number of holes simultaneously, even in cardboard, requires great power, and entails enormous shock and great wear on the machine ; to obviate this difficulty, the punches are slightly varied in length relative to their keys, so that they will not all act on the cards at exacdy the same instant, and the strain on the machine and power required are thereby greatly reduced. A Lace- Hole Press Is indispensable to the machine. This is a separate little machine, designed to set upon a bench or table, and is used especially for cutting the peg and lace-holes. It may be operated very readily by hand, but if desired, is easily adapted to run by power. The feeding is done by one motion of the hand, and once handling of the card; the cards leave the press by gravitation, and arrange themselves in piles. The press is arranged to cut cards for 400 or 600 machines. ^7 The Lacing of Cards. Two methods are observed for lacing Jacquard cards : A, hand-lacing on a common frame; lacing by power. A. Lacing of Jacquard Cards by Hand. For this purpose the cards are put on a common frame containing on its surface pegs of a corresponding size to those used on the cylinder. "The pegs on the frame are made of hard wood, and the pegs of the cylinder of brass. These pegs on the frame are located at exact distances apart, and the frames are. built to hold from 30 to 50 cards, supe'rficially arranged. Figs. 30 and 31 illustrate the frame under S, showing at a three cards ar- ranged for a fabric, with a twill effect from left to right ; and at b the same cards IK 9 9<4 0 • 0 0 0 . i 0 0 0 ^ 9 0 .0 0 *: 0 0: JO, I ojl tlu 0 :(K». 0 :' i ICS.' 0 0 j X't tiu e.ft :o Fig. 31. Fig. 30. arranged for a twill in the opposite direction, from right to left. These frames are arranged to slide into each, so as to adapt them to the distances of the peg-holes in the cards. To give a clear understanding as to the distance of these pegs from each other a few measures most generally used for lacing frames are given. 1. For a 200 Machine (French Index.) ' The centre of the pegs are 2^" apart. Width of cards 2-^", allowing j^" for distance between the cards. Diameter of the pegs at the bottom. Distance of the centre of one peg to the centre of the corresponding one across the frame, 7}i". Length of card, g%". 2. For a 600 Machine (French Index). The centre of the pegs are 3f^" apart. Width of cards, 3%", allowing }(" for distance between cards. Diameter of the pegs at the bottom, Distance of the centre of one peg to the centre of the corresponding one across the frame, 145^". Length of card, 16%". 3. For an Ingrain Carpet Machine (American Index). The centre of the pegs are 3" from each other. Width of cards 2^", allowing 5^" for the distance between the cards. Diameter of the pegs at the bottom, Distance of the centre of one peg to the centre of the corresponding one across thfe frame, 11 f^" Length of card, 13%". * 98 B. Lacing of Jacquard Cards by Machine. Different styles of machines are constructed for doing this work, among which we find machines requiring two needles for each series of holes in the Jacquard cards, and machines using one shutde in connection with each needle. The Jacquard cards mostly needed are for machines containing 400, 600, etc., hooks and needles. The Jacquard cards for these sizes have three series of lace-holes, and the number of needles, or needles and shuttles, used in the machine, is proportionally increased. The Method of using Two Needles for Lacing each Series of Holes Is the one most extensively employed, hence we will take this machine (W. P. Uhlinger, Phila., builder,) for the subject. Fig. 32. Fig. 32 represents the perspective view of a lacing machine for 600 Jacquard cards. The table is located at a convenient height, and is 33^ by 36^^ inches. Two grooves, each inches by 26^ inches, are located five inches from front and rear respectively, and 9^^ inches from each side. A third groove of the same size is situated in the centre, inches from the others. An endless chain runs in each groove, consisting of 24 links, corresponding in length to the width of the card to be laced. Each link of the two outside chains has a peg of a size corresponding to the one used on the cylinder in the Jacquard machine. 99 Fig. 33 illustrates the side view of a link, and the method of jointing: a, the peg ; c, the joint of link ; the length of each link being 3^ inches, and the height Fig. 33. Y2 inch at the joint ; the diameter of the pegs at the bottom, % inch ; the height of each peg, ^ inch. Fig. 34 shows the top view of Fig. 33, illustrating two complete links. The body of each link is 2 ^ inches long ; the head, ^ inch long ; the slot, i inch long. a represents the peg ; e the empty spaces between each pair of links, to receive the t V n Fig. 34. teeth (i^ inch high) of wheel (8 inches diameter. Fig. 36). This wheel holds and guides the endless chain ; also imparts the required movement to the cards. It is regulated by a cam arrangement. [See Fig. 35.] Fig. 35. I'iG. 36. Two needles are required for each of the three series of lace-holes, or six needles in all. The process of lacing each series is the same ; as the three horizontal working needles are connected to one rod ; thus, by working this rod, they are operated correspondingly. The three vertical working needles are arranged in the same manner, and also the three loop-guides. Fig. 37 shows a top view of one of the loop-guides, d, a, c. The dotted lines near a represent the position of the corresponding "presser" for the cards during the lacing process.
