VAN NOSTRAND COMPANY, 1906. s^^ Property o f College of Architecture,; £ofneJI Univer^ Copyright, 1895. D. VAN NOSTRAND COMPANY. F R E F^ C E . In looking over the books on lettering, which have come under the writer's notice, he has found, that while doing full justice to the principle of ornamentation and the theories governing the shaping of each letter, no author has as yet attempted to treat lettering from a purely practical point of view. The need of a practical work on lettering, however, has been and is daily experienced by many draftsmen, and in the following pages the writer has endeavored to set forth the proper methods of forming purely free-hand lettering in a simple, easily acquired way, giving, at the same time, the proper safeguards against the errors most commonly committed. The letters exhibited are actual free-hand work and can readily be copied. In this respect the writer has made a radical departure from works of a similar charac- ter which generally give ornate, carefuUy engraved alphabets, being of little more use to the average draftsman than ordinary printed type, i. e., they can only be copied with a great sacrifice of time and patience. The whole system out- lined is the result of the writer's experience during years of practice on the staff of a leading technical journal and is in- tended to be a thoroughly practical guide for doing the best class of work in the shortest possible time. Bbooklyn, September, 1895. CHAS. W. EBINHAEDT. PEEFAOE TO EIGHTH EDITION". The encouraging reception given to former editipns of this book has convinced the writer of the practical use- fuhiess of the system of lettering which he advocates, and has induced him to add material which tends to enlarge the scope of the book, making it complete in eVery respect. The subject of lettering, as applied to working drawings and the construction of titles, has been taken up more in detail, and the chapter devoted to lettering for purposes of photo-reproduction wiU, be found interesting and useful by many readers. Besides the extension of the text some twelve illustrations and three full page plates have also been added, thus considerably enlarging the work, which, it is hoped, will continue to prove a desirable hand-book to those wishing to acquire the art of freehand lettering in a simple and rational way. 0. W. E. INCLINED LETTERING. TN the following system of lettering no attempt has been made to imitate any special form of printed alphabet, and for all ornate and elaborate lettering the draftsman is referred to some one of the many published collections of this character. What is here intended is to illustrate and describe a type of lettering that looks well upon working drawings ; is reduced to its simplest form ; one that is rapidly made and is clear and distinct under almost any reduction by photography. It is, in fact, especially designed for photo-reproduction. With the purpose of fairly treating the subject, the lettering here illustrated has been reproduced without any attempt at touching up or cleaning ; it is actual freehand work, such as should be used in general practice. The ordinary slanting and, further on, the upright lettering are described in a somewhat detailed manner, as when the draftsman once becomes proficient in form- ing these two types properly, it will then be a very easy matter for him, to form also the more ornamental letters satisfactory. The first requisite is to produce sharp, clean corners and bold lines of uniform strength, and this is especially necessary in work for photo-reptoduc- tion, as usually such apparently unimportant things as filled-in corners and uneven lines are greatly exaggerated on the plate. , In Fig. i the correct and incorrect ways of doing this are shown. It will be well at first, for the purpose of obtaining clean corners, to resort to the One Stroke Letter/nq ^'^'^"^ °^ '"^'^^'^l '""'^l''^ Incorrect "^ the lines outwards at their One Stroke Letteri'nq ^nds, as exhibited on the '^o''''^'^- third line of Fig. i. For One Stroke Lettering very large letters the writer Fig. 1 finds a " ball-point " pen (Leonardt's 5 1 6 F.) most satisfactory ; for medium sized letters, not less than 2 millimeters high, he uses Soen- necken's No. 108 or 208, and for. small-sized letters, Gillott's No. 303, or Blanzy, Poure & Co.'s crow quill pen. All of these pens should be "" broken-in " somewhat before being applied to lettering; they should also be frequently cleaned when using waterproof ink, especially the " Soennecken " pens. The nibs of the pen should, while doing this, be worked back and forth gently against a soft rag, which process will cause the dried-up particles of the ink to drop out from between ' them. As to the type of lettering to be employed, the slanting letter is well adapted to descriptive matter, dimensions, etc., while the upright letter will contrast well with the former type used as reference letters or sub-captions. A uniform pressure should be brought to bear upon the pen — a trick only acquired by practice. The pen should be held pointed forward, as in ordinary writing, and not sideways, as in " round writing." In lettering on tracing linen a sheet of black cross-section paper divided to millimeters, such as given on detached plate (XII) accompanying this book, will be found useful for indicating the proper spacing, .^lant, etc. On drawing paper, pencil guiding-lines will be indispensable to the beginner. A slope of I to 2^ is sufficient fof the stems or down-strokes of the letters, and ordinarily an angle of 45° with the horizontal will suffice for the up-strokes and the axes of ellipses, excepting that of the letter " o." The latter angle will have to be increased, of course, when the lettering is compressed, as shown in Fig. 2. In lower case letters, like "b" or "p," with parts extend- ing above or below the main body of the letter, the length of these parts should be about 2-5 the total height ; the body of the letter representing 3 parts of the total height. The exception is the lower case " t," which is one part less in total height than "b" or " h," for example. In the illustrations following, the incor- rect forms of letters, as being constantly observed by the writer, are shown in brackets, and thd correct method of forming each letter is shown beneath. Fig, 2. Lower Case Letters. The letters " n " and " m," Fig. 3, should be made with almost sharp upper corners ; " u " is best formed by three strokes, as in this way parallel positions are secured for Fig. 3. the straight lines, which should be made first, and these can be then joined by a lower curve. In forming the letter " v," Fig. 4, make the first stroke nearly vertical, and the second at an angle of about 45° with the horizontal. The common error in making this letter lies in curving the two lines and giving the letter the The letter " w " is formed on the same principle as the " v." In putting in the short hori- zontal cross-line of the " t/' Fig. 5, great care should be taken to use Fig. 4, appearance of a Fig. 5. very little pressure upon the pen, as otherwise the ink will spread at the intersection of the two lines and make clean corners impossible. The second part of the letter "r" should be purely an up-stroke, slightly curved at its end. In making the letter " f," start with a curve extending down about one space ; the "f " shown in brackets would come out with a heavy black knob at top in any considerable re- duction. The rule laid down Fig. 6. for forming the " n" may also be applied to the letter "h," Fig. 6, and the down-stroke for the " j " is practically the same as for the " f " revers- ed. Make bold, oblong dots over the "i " and "j." The third stroke of the letter " k," Fig. 7, should be vertical and begin at about the middle of the second stroke. In constructing the letter " x," care Fig. 7. should be taken to have the first stroke either verti- cal or leaning slightly backwards, and the second stroke ought to cross the first a little above its centre ; in order to produce a clean intersection it may be well to make the latter stroke in two parts. The letter " y," Fig. 8, should be drawn on the lines of the " v," and from the point of the angle the tail should be drawn with line the Fig 8. ^" exact upper down-stroke, terminating, if desired, in a slight curve to the left, to avoid the little blot of ink which would otherwise form at the bottom of the stroke. In this letter the second stroke may be modified as shown. The "z" is best drawn in one stroke, stop- ping the pen every time before changing direction. The letter " o," Fig. 9, is produced by two curved strokes, with their ends sufficiently bent, forming a perfect ellipse, the axis of which lies in the direction of the down-stroke. The joining of these two curves, in this and similar let- ters, can be effected very neatly after a little practice. The ovals of the following letters should be made somewhat narrower at the top than at the bottom, for obvious reasons ; and especial care must be taken to have the axis of these ovals lie at an angle of 45° with the horizontal. For the purpose of increasing the width of the enclosed space at the bottom of the down-stroke and the oval, the right-hand curve should be somewhat Fig. 9. flatter than the opposite one. For the advantages of so doing see Fig. 9. In these letters the down-stroke should be at ex- actly the proper angle, rather in- creasing this angle at the be- ginning, for the learner almost invariably makes the mis- take of drawing this stroke too slanting. To further guard against this error, the beginner may slightly curve the end of the down-stroke towards the left, thus widening the angle at the bottom of the " a " and " d," and the down- stroke of the " g " should be made as long as possible in its straight part by turning very short with the lower left- hand curve. The letters " p " and "b," Fig. 10, should be shaped exactly as in- d" and practice these letters can also be made to look well by verted letters " q." With Fig. 10. using the oval of the letter " o." The letter "c," Fig. 11, is formed with one stroke, care being taken to have its general direction parallel to the down-stroke. The '-' e " is commenced in the same way, and the upper loop is formed by a second stroke with the axis of the loop again at an angle of 45°. The beginning of the " s " is a very short curve •^'S- IT- from left to right at its apex ; the rest is carefully joined on, turned down into a neat ogee curve and finished by a little crook upwards. The middle part of this letter should be nearly horizontal. If a very narrow letter is to be produced, it may be constructed with one stroke and a flatter curve, making the upper curve somewhat shorter than the lower one. In the ordinary letter a first separate stroke at the top is made necessary by the fact, that while turning in a hori- zontal direction from right to left and then descending into the ogee curve, the pen will either clog up and not give the required strength of line at one stroke or other- wise will in turning detach minute particles of paper or tracing-cloth saturated with ink and deposit them at the side of the stroke, necessitating erasures. The method outlined (employing two strokes) is therefore by far the simplest and quickest way of producing a clean letter, as experience will show. It will at first be a somewhat difficult matter to the beginner to lay the main axis of this letter parallel with the down-stroke, but this is nevertheless an essential point and should not be lost sight qf. Capital Letters. As in the rule laid down for the lower case letters, the capital letters will generally be five spaces high. Sharply defined clean corners are again necessary, and to secure this the beginner may find it advantageous to curve the upper and lower ends of the down-strokes a little outwards. -The letter "A," Fig. 12, should be made in three strokes, with the second almost vertical. The cross- stroke should be placed low — about the middle of the Fig. 1 2. second space from the bottom. The short third stroke of the " E" should be slightly above the center of the letter, and should not be too short. The two down-strokes of the letter " H," Fig. 13, should be ex- actly parallel, and the horizontal stroke should be made as directed for the third stroke of the " E." If the capi- tal " I " is to be followed by a lower case "1," two short horizontal strokes of even length and projection may be added to the top and bottom. The second stroke of the letter Fig. 13, "K" should join the first at the top of the second space from the bottom, and the third stroke should join the second nearly one space higher up. The letter " L" can easily be made with one stroke, analogous to the forming of the same stroke of the letter " E." The "J," Fig. 14, is commenced as a perfectly straight down-stroke to the top of the lower space; then it turns to the left in a gentle curve, tangent to the base line, and finally rises to the top pig_ ,4, of the first space. The " M " is made with four separ- ate strokes, putting in the two parallel lines first ; the two other strokes should join at the top of the first space. If desired, this letter may be made slightly wider at the bottom than at the top. The letter " _N " is also formed by drawing the two parallel strokes first. The horizon- tal stroke of the " T " should be neatly balanced on top of the down-stroke, and if it is not perfectly straight, as often is the case, a hardly noticeable crook downwards , , at both ends will improve it. The letters shown in Fig, i5 are to be con- Fig. 15. structed precisely upon the lines laid down for the cor- responding lower case letters, with the exception that they should be a trifle narrower in proportion. The " Y" is formed with two strokes without any lower crook to the left ; the " Z" is made in one stroke, with the axis of the letter in the direction of the down- stroke. found easier, this Fig. 6 Z " can be made with three strokes. 10 With practice the letters "P," "B" and "D"can each be formed with two strokes, with the curves terminating as shown. In forming the two curves of the letter " B," begin at the top, and after joining the stem, return exactly on the horizontal while the ink is yet moist and complete the lower curve. The space enclosed by the lower curve should be somewhat larger than that in the upper one- The curve of the " D " should be parallel with the down- stroke in its middle third, but it may sometimes be ad- visable to make the lower part of the " D " a shade wider than the upper part. The first and second strokes of the " R " are identical with the letter " P." The "C," Fig. 17, is formed with one stroke, nearly completing the ellipse of the letter " O," though this let- ter should be proportionately narrower than the lower case " c." In making the " G," a somewhat wider ellipse is required, and this letter is most easily made with two strokes; the second horizontal stroke should be about one-half of the total width of the ellipse. Fig. 17. The capital " O " should be an almost perfect ellipse, special care being taken in joining the two curves. The third stroke of the " Q " should begin about the middle of the second space, and extend one space below the base. The letter " S "• can be formed, for small-sized lettering, in two strokes, or with an additional stroke, as shown, for larger letters. Numerals. As a rule, numerals should occupy the same height as capital letters, or five spaces, though the use of fractions may slightly modify this rule. When the numeral "i," Fig. 18, Fig 18. is used in proximity with " I " or " 1," it is well to use a short up-stroke at the top ; otherwise, it may be repre- sented by a simple down-stroke. The "4" is commenced with the stroke inclined at an angle of 45°, terminating at the second space from bottom and then turning sharply into the horizontal. The down-stroke should intersect 11 the horizontal in such manner as to leave about 3-5 of the horizontal to the left of the down-stroke The " 7 " is best formed with one stroke, the down -stroke being on an angle of 45°. The " 3 " should be drawn in one stroke, beginning as with the " 7 " to a point a little below the top of the third space, and then curving into a portion of an ellipse, with an axial angle of 45°. Another type of the numeral " 3 " is shown, which can be made in one strolce also. The "o" Fig. 19, Fig. 19. ought to be a perfect ellipse, like the capital " O." The " 5 " is commenced with the down-stroke, ending in the ellipse of the " 3 " and the horizontal upper stroke. The " 2 " can be constructed by one stroke, beginning at the top of the fourth space, nearly completing an oval with an axial angle of 45°, and then turning shortly into a down-stroke running into the base line, where a sharp turn is made in a horizontal direction. The " 6," Fig. 20, is commenced Hke the "p," Fig. 20. except that its initial point is somewhat beyond the axis of the ellipse. For that rea- son the first stroke is very short, curving to the right ; the second stroke descends nearly to the base, where a stop is made, and the pen then returns in the same stroke, and, gradually turning to the right, nearly completes an ellipse with an axial angle of 45°, joining its lower part with the bottom of the incomplete second stroke. The figure " 8 " is commenced with an ogee curve, using a slight crook at its lower end, and is finished by two other curves, as shown. The lower loop should always be somewhat larger than the upper one. The numeral " 9 " is made in two strokes. The ellipse at the top is nearly finished in one stroke when the down-stroke is assumed, which, beginning at the initial point of the ellipse and completing the latter, terminates with a somewhat fuller curve then that employed in lower case ''g." Though Roman numerals are seldom employed on working drawings, they may sometimes be re- quired. The chief requisite is to so form them that they are neat in ap- distinguished from the pig. 21. rest of the text. They should be of the same height as the Arabic numerals, and short horizontal strokes 12 should be used with them, as indicated in Fig. 21. In the modified forms shown in Fig. 22 it will be noticed that all the letters and numerals are based upon the general form of the letter " o," modified to suit de- mands. The second stroke of the ■ " r " is really a part of the elemen- tary ellipse, as are also the second stroke of the " n " and the second and third strokes of the "m." The " u " is here made in two strokes — the first, a down-stroke with the curve attached, and the second a straight down-stroke, tangent to and touching the curve. The numerals follow similar lines of construction. The " 2 " begins at the upper part in an ellipse and ends in a down-stroke, laid at an angle of 45°, turning sharply to the right in a horizontal line. The " 3 " is formed with one stroke, with its lower curve, as also that of the " 5 " and " 6," encircling somewhat more than half of the ellipse. In the " 6 " and " 9 " care must be taken to have the curved down-strokes only tangent to the respective ellipses, and not cutting off a portion of the latter. UPRIGHT LETTERING. Upright lettering is employed most advantageously for reference letters, designating lines of section, and for captions. In some instances however, it may be deemed advisable to use uprights also for such descrip- tive matter, dimensions, etc., to which some prominence is to be given, though, as a rule, the slanting lettering will answer this purpose very well. The relative height of the letters ought to remain the same as that of the inclined lettering. The down- strokes should be perfectly vertical, and in order to pro- 13 duce this effect properly, it will be best for the beginner to form the habit of making the letters at first lean over somewhat to the left at the top, as the natural tendency would be to have them lean the opposite way. It will be noticed that in some of the uprights a comparatively greater number of strokes is required, as many portions of these letters are being executed in a horizontal direction or nearly so. The letters are again simplified as much as possible, a fact which will be especially notice- able in the lower case "a" and " g," which, though at variance with the ordinary gothic print, look fully as well. Lower Case Letters. In the letters shown in Fig. 23, the same number of strokes is employed as in the slanting lettering pre- viously described. The letters are as a rule made wider than those of the slanting type. The second stroke of the " n" and the two last strokes of the letter "m" are started with a very slight curve in an upward direction rounding off the corner at the top,. making it somewhat more full than in the corresponding slanting letters. The letter "u" is made in three strokes as usual, Fig. 23. connecting the two down-strokes with a well shaped curve. If preferred, however, the ordinary form of gothic lower case " u," as shown, may also be employed. In constructing the letter " v," the two slanting strokes ought to make the same angle with the vertical. The beginner will in- variably construct the second stroke at a greater incline than the first, and will do well to guard against this habit, until after some practice the' hand will become accustomed to form the point of juncture of the two strokes equidistant from their starting point. The letter " w " is composed practically of two somewhat narrowed V s. The' letter "1" (Fig. 24) is sometimes constructed with a lower crook to the right, when used at the side of capital letter " I," otherwise it is made as a down-stroke pure and simple. The second stroke of the " r " starts 14 from the top of the second space upwards as a very sHght curve, similar to the one forming first part of the second stroke of letter " n." Letter "f " is best formed by three strokes ; the first a very short curve to the right, being joined by the second or main stroke. The horizontal third stroke should be made sufficient- ly prominent. Fig. 24. The letter " j " ought to extend two spaces below the base line and should be made in one stroke, being perfectly straight until the point of curve is reached. If found easier, however, a second right hand stroke, form- ing the curved portion, may be employed. The latter should be almost a semicircle and one space high. The second stroke of letter "k"'(Fig. 26) should extend down to nearly the first space. The third stroke be- ^'E- ^S- gins at about the centre of the second one. The letter "x" is constructed with- two strokes, making the first one apparently more inclined than necessary for reasons explained above. When the pen is very full^ the second stroke may be made in two parts, as shown, thereby preventing the forming of a clot of ink at the intersection of those two strokes. The upper part of letter " y " forms a perfect " v." The second stroke may either be executed with a slight angle terminating in a vertical direction, or in a perfectly straight inclined line, according to the draftsman's individual taste. Letter "z" is as usual formed in one stroke ; its starting point should be vertically above the point of turning into the horizontal. The ellipses of the letter shown in Fig. 26, are as usual constructed in two strokes, joining the respective initial and terminal points carefully. The first curve starts in an almost horizontal di- rection towards the '^'S* ^"• left and terminates similarly at the right, thus prevent- ing the forming of a point at the top and bottom junctures. The second (right hand) stroke of the ellipse ought to be made apparently more curved than necessary, as that portion is invariably made too flat by the beginner. The ellipses should be made quite full. The vertical 15 down-strokes of letters " a," " d " and " g " ought to run tangent to their ellipses so that the thickness of the second curve at the joint of juncture is not increased. The curved portion or the fourth stroke of letter "g" extends to the left almost or nearly the full width of the oval of this letter. The mode of construction of letters " q," " p " and " b '' (Fig. 27) offers no novel features. If the pen, while rounding in the lower part of the curve of letters " p " and " b," should contain too much ink, the curve may be completed by a third stroke, running in an opposite direction, as shown, as in turning into the lower' portion of the curve a somewhat greater pressure is involuntarily brought upon the pen, resulting if too full, in a badly proportioned lo^yer end. Fig- 27. Letters " c " and " s " (Fig. 28) are started with a short curve towards the right ; the upper end of letter " c " should be slightly more curved than the lower one ; still, the form of the perfect oval should be predominant in this letter. The letter "e" is constructed in three strokes. If, as is sometimes the case, the upper part of letters " c " and " e " should not precisely fill the allotted space, or otherwise they should appear too narrow, a slight flat- tening of the lower portions of the curve, making those letters appear leaning back- Fig. 28 ward^ will help matters and otherwise not at all injure their appearance, as shown. The completed ovals of letter " s " should, as in the inclined one, form a perfect figure " 8." If at all uneven, the lower oval should be made more prominent than the upper one. Capital Letters. Upright capitals are, as a rule, 5 spaces high, with the exception of the " Q," the appendix of which ought to reach one space below the base line. These letters should be made narrower in proportion than the cor- responding lower case letters. The second stroke of letter "A" (Fig. 29), should 16 be made rather more inclined than the first one by the beginner. The first strokes of letters " E " and " F " must be made perfectly vertical or leaning back- wards, as even the slightest inclination forward in these two letters will be painfully noticeable, especially in the " F." The length of the short third stroke in the " F," is generally depending on the shape of the succeeding (lower case) letter ; shorter, if the latter begins with a verti- Flg, 29. cal stroke, longer, if an oval or inclined stroke is to follow. We will not attempt, however, to lay down any definite rule on this point, as the determining factor in eachi case should be the draftsman's eye and good taste. Letter " Z " is best formed in one stroke, care being taken to make especially the inclined portion perfecdy straight. The letters comprising Fig. 30 are constructed upon nearly the same principles given in the case of the cor- responding slanting capital letters. The termination of the last stroke of Fig. 30. letter " K " should in a well formed letter be vertically below the initial point of the second stroke. The length of the horizontal portion of the " L" is again, as in the case of the " F," determined by the succeeding (lower case) letter. It is obvious, that by unduly lengthening that portion of the letter, an unproportionally wide space will result between its vertical part and the succeeding letter. The curved part of letter "J " (Fig. 31) ought to be a well shaped semicircle, beginning and ending not above the middle of the second space. The second and third strokes of letter "M" converge at the second line, and this point should, of course, be at an even distance from the vertical strokes. To attain this end exactly, some draftsmen will per- Fig. 31. haps find it easier to put in the two verticals first and the oblique strokes afterwards,' as in the construction of the letter " N." The angles in those two letters should be sharply defined, the strokes forming them ending in a clearly cut, though somewhat blunt point. The second horizontal stroke of letter " T " ought to be evenly balanced upon the main or down-stroke. 17 The construction of the letters shown in Fig. 32 is chiefly guided by the principle that the rate of inclina- tion of the slanting strokes should be uniform in each letter. In the case of the "V" and " W " care should be taken Fig. 32. that only the center lines of the inclined strokes join at the base or top lines of the ruling, thus avoiding two extremes, either the formation of a vertical short end or the reverse, a flattened-out point. This is made apparent in the small illustration. Fig. 32a. The first and fourth strokes of letter " W" ought theoretically to be made imom^ parallel to the second and third; pjg 32^ but as the latter two strokes are involuntarily made more upright than the first one, the fourth stroke should again be made more slanting to correspond with the first. The reverse mode of procedure would result in a badly shaped letter, as shown in brackets. Letter " X " is usually made in two strokes, or, if preferable, a stop may be made in the second stroke shortly before crossing the first, continuing it on the other side, avoiding thus the forming of a lump of ink at the point of intersection. The two inclined parts of letter " Y " should join on the top of the second space ; from there the second stroke is continued in a vertical direction down to the base line. Letter "P" (Fig. 33) is constructed in two strokes, the second one beginning at the top of the first, care- fully round- ing the curve and joining ^„ the first Fig. 33. stroke again at right angles as a perfectly straight line. The third stroke of letter "B" begins at the point of curve of the second, enclosing a slightly larger area than the second one. The second stroke of letter " D " should begin and terminate in a hori- zontal direction. If a slight " sagging " should happen in the curve, it ought to be near its lower portion. The rule given for the forming of the second stroke of letter " B " applies also to letter " R;" its third inclined stroke begins at the point of curve of the second. The two vertical strokes of letter " U " are made first ; a right hand carefully formed semi-circular curve con- nects the two. 18 Letter " C" (Fig. 34) is made with two strokes, and is simply a repetition of the lower case letter^ relatively narrower. The second stroke of letter " G " follows the outline of the ellipse up- wards near- ly a space ; there a short stop is made and the pen point is carefully pushed up- wards in a vertical direction, terminating that stroke as shown. The final horizontal stroke should not be made too short. To those who- might find it difficult to exe- Fig-34 cute the second stroke neatly in the way outlined the suggestion of a separate vertical downward stroke is made. The mode of construction of the ellipses of the "O" and "Q" differ somewhat from that of the lower case letters ; the point of juncture is shifted diagonally in order to lessen the chance of a point forming at the top and bottom of the oval. The third stroke of letter "Q" begins as shown, and extends one space below. The second stroke of letter " S " should for a very short space run perfectly horizontal. The rules given for the forming of the lower case letter otherwise apply to this letter also. Numerals. Upright numerals ought to be like the inclined ones, five spaces high. Figure " i " may again, if used in proximity with capital letter"!" or lower case "1," be con- Fig. 35. structed with a very short upstroke. Numeral " 4 " is started with a perfectly straight inclined downstroke, as shown, whence it assumes a horizontal direction. The rule given above and illustrated by Fig. -^la on the forming of a clear cut angle, applies to the top part of this figure espec- ially. The lower terminal point of numeral "7" should, in a perfectly formed figure, be vertically below the center of the horizontal portion. The upper part of numeral "2" ought to form portion of a flattened oval. The mode of its construction is clearly shown in the illustration. Fig. 35. 19 Numeral "5" (Fig. 36) begins with a vertical stroke to nearly the middle of the third space; from there the stroke follows the outline of the ellipse,, which is to be three spaces high. The middle portion of the second stroke of numeral "6" ought to follow the vertical direction a short distance, as the general tendency in constructing this Fi^. 36. figure is to have that part too much curved. The third stroke ought to enclose a perfect ellipse. Numeral " 8 " is formed in three strokes ; its first a well-shaped ogee curve, with its middle portion running very nearly horizontal. The first stroke of numeral " 9 " ought to be part of a perfect ellipse and comprising as it does, nearly two-thirds of its circumference, is somewhat difficult to construct. The middle portion of the second stroke should for a short distance, run almost vertical. The upright ^ Roman num- erals, Fig. 37, Fig. 37- are constructed, analogous to the inclined ones, with upper and lower short horizontal strokes. After explain- ing the mode of forming of capital letters " V " and " X," nothing new can be said concerning these, except that as a general rule it will be well to make them a trifle narrower in proportion. Extended Form of Upright Lettering. In the following illustration, Fig. 38, the upright letter- ing is shown in extended form. It will be noticed that for the construction of some of those letters a compara- tively greater number of strokes is required. The axes of the ellipses lie in a horizontal direction in every case, and it will be well to shape parts of the curves, composing them, decidedly flat, sometimes going to the extreme to have the top and bottom parts of the ellipses running perfectly straight for a certain distance. The complete alphabets of the slanting and upright type are shown in Plate I., together with samples of lettering as used on working drawings. The single 20 letters, composing a word, should, especially in slanting lettering, be placed as close as possible, so close, in fact, Sufficient space should be allotted between different words. Of all the theories set forth upon the spacing Fig. 38. that they sometimes nearly touch each other. If this principle is followed out at first, the golden middle gov- erning the spacing of letters will soon prevail. The beginner generally spaces his letters too far apart. of lettering the writer has found that no one really " works " in practice ; therefore he would advise the draftsman to depend solely upon his eye in determining the proper space. The spacing of a word for instance. 21 should be so arranged that, when the drawing is held at some distance, or is looked at with half closed eyes, :;::;::';":: only standard. between letters, as °" shown for example ONLY STANDARD, in Fig. 39a, which, (Corseted.) an actual specimen Fig. 39. ' of printed type, demonstrates the fallacy of one of the theories upon spacing, and should appear corrected as in Fig. 39( iWW variable Freehand Lettering applied to Working Drawings. Lettering as applied to working drawings, should be side, and a dotted reference line with arrow head point- bold, clear and uniform in size, with 1' the exception of the sub-captions, which ' may be a trifle larger. Diminutive and cramped lettering on a drawing will never look well. If possible, the letter- ing should be kept distinctly by itself and never be allowed to run across lines. If some words can not be put on the ob- ject itself, which they are intended to des- cribe, they should be boldly placed out- iaitlmn, T t hick, irionq. K ■ Z'b'- Sidewalk. ENti.NEWS.

The title given under Fig. 48 Is one of the standard arrangements of the concern named and shows good points. The lower part, as noticed, Is stamped on the drawing, and the blanks are subsequently filled In by hand. A style of title seldom used nowadays Is that shown In Fig. 49. The letters are arranged in curved lines and an ornamental, flourished effect Is sought after. Where such is desirable, the gen- eral scheme is a fairly satisfactory one. A few words in regard to centering of titles may here be added. A title should in nearly all cases, be arranged systemetlcally about a vertical center line. After the location of this line and. the height and spacing of the different lines of letters have been determined, the spaces equal to the width of the letters can be marked off with pencil on the edge of a strip of paper and the center of the strip placed on the vertical center line of the title, with Its edge just below the line of letters to be sketched. The letters can then be penciled In very readily. A space between words counts as a letter In spac- ing, therefore, a line containing three words of J, 3 and 6 letters represents 18 divisions, so that 9 divi- sions, or the first word, one space and one letter of the 30 second word are to come to the left of the center line, and the remainder of the line to the right. If, after all, the spacing of a line of letters needs re-ad- justment after the letters are sketched in, the drafts- man may easily rectify the matter by going over that line again, working first to the left and then to the right of center. shows the draftsman's lack of practice in freehand work, Qcn^J^ r^'T. outlet Sewer U rSsVl ty V<.^t Ca^keCity ^^^^ Alio 1 N DEX TO MAP IN — SHEETS ATTACHED Fig 49.

BEPRODUTION FROM EITHEB OF THE ABOVE ORIGINALS. reduction is one-third its condensed on drawings A drawing should never be reduced at a lesser rate than to three-fifths of its original length. What may be called a good average the two-thirds (i. e., to length.) When the type of lettering is used for reduction purposes a proper safeguard to adopt is to exaggerate somewhat the width of ovals or small loops, such as for instance of the letter " e," to guard against the " filling in " of those parts. A close study of the three types of lettering given on Fig. i of this work, which tend to illustrate the same principle, will also be useful. The reason for giving a limit of reduction (i. e., one i'tliicir-..

Section of Cast Iron Cap Fig. 526. millimeter height for smaller lower case letters) and the employment of gothic letters of uniform strength is made evident by referring to the illustrations, Fig. 52«, 33 which presents an example of engraving, such as is sometimes indulged in, and Fig. 52<5, redrawn and reduced to some scale. The strength of the lines of a drawing to be repro- duced depends of course altogether upon the rate of re- duction. For larger reductions it will be quite essential to show as much of a white space between lines as possi- ble, for instance such as designates the thickness of flange of an I-beam in elevation. The .work should in all cases be clear and open, and this detail, immaterial as it may appear, not be overlooked. The processes of photo-reproduction ordinarily em- ployed are the photo- lithographic and zinc etching pro- cess. Both require a similar grade of preparation of the drawing. The writer uses on such drawing the water- proof ink, which is perhaps blacker than the ordinary kind and possesses more body, Any kind of black drawing ink^ however, is suitable for the purpose ; well rubbed stick India ink will permit of very fine black lines. The main objection to the use of ordinary inks, however, is their liability of blurring, when handled, or the ink mixing with the Chinese white, render- ing the application of the color sometimes very difificuh.

ENGINEERING NEWS A Journal of Civil, Mechanical, Mining and Electrical Engineering. Founded 1874. Published every Thursday at 220 Broadway, New Tork. Subscription $5 a year to any part of the trorld. The Engineering News circulates in every part of the world and has a larger list of actually paid subscribers than any other Engineering Journal published. Its readers represent the many interests in the field of Engineering, Contracting, Railroading, Manufacturing, Municipal work, Engineering Education, etc., and every one finds a personal value in its pages. As a literary magazine it forms a continuous and up -to date weekly record of Engineering progress in America that cannot be equaled, and as a commercial medium it makes itself indispen- sable to Contractors, Manufacturers and others who are on the ^wzz/zz/^ for new business, presenting exceptional opportunities for buying and selling all kinds of machinery and supplies and for wide competition on all classes of contracts. ENGINEERING LITERATURE A Supplement to Engineering News, issued about the middle of each month, gives lists of books published during the month and reviews of all the principal books written by recognized authorities on the different subjects, together with other information regarding Engineering Literature. Second Edition " Awhile deprecating any need- lessly elaborate finish, the writer advises the use of just sufficient shading and finishing touches to render a drawing thoroughly comprehensible and to preclude any possible ambiguity. ' " The illustrations in this work, quite a number of which have appeared in the columns of 'Engineering News,' are in- serted to demonstrate the points involved and have been reduced more or less in size so as to save space. They may however be copied by enlarging to about 3 or 4 times their linear dimensions.'' Post- Price, $1.00 pafi " It is of course to be under- stood, that this book is not a manual for beginners' exactly ; it serves its. purpose best, where used by the draftsman who is familiar with the mathematical principles of mechanical drafting. It will then, as the writer hopes, prove a valuable aid to the rapid production of neat, correct and legible drawings." (PREFACE. ) Second. Thoroughly Revised and Enlarged, Edition 90 Text Illustrations, 11 Plates. Price. $1.00 TESTIMONIALS "I have examined the book carefully and am much pleased with it. Mr. Rein- hardt is to be congratulated on having clearly, simply and briefly explained the methods he has used in making his drawings remarkable for their great clearness and legibility It is a book that should be on the desk of every draftsman."— Prof. C. B. Wing. Leland Stanford, Jr., University. ••1 find it most excellently adapted to tlie purpose for which it is intended."— Prof. Walter Flint, University of Maine. "Am greatly pleased with it; itoccupies a field of its own among books on draft- ing, "—Prof. Robt. L. Lund, Vanderbilt University, "It should be in the library of every draftsman. "-Prof. C. W. Marx, Missouri State University. "It admirably fills a long-felt want."— Prof. John L. Mnnn, Thayer School of Civil Engineering.- "It is certainly the best compendium of instruction and elegant examples that I have slen."-Prot. Robert Fletcher, Ph.D., Director Thayer School of Civil Engi- neering, "It will form a useful supplement to Mr. Reinhardt's 'System of Lettering.' " —Prof., E. H. Lockwood, Sheffield Scientific School. "Have adopted it as a reference book for our civil engineering students. Your 'Lettering' has been the means of bringing about a distinct lift in the standard of freehand lettering, and, 1 predict a like result in the field covered by your new work."— Prof. W, D. Pence, Purdue University. "Reinhardt's 'Technic of Mechanical Drafting,' is a book that should he in the drafting department of every engineer's office. It describes those subtle details in execution which constitute the essentials of effective expression in a drawing, both as to truthfulness in its representation as well as its artistic finish. This state- ment is admirably illustrated by the contrasts shown in Figs, 6, 7, 22 and 46. In view of the important part of detail drawings in all kinds of construction, it is an important service/ to show how the element of thorough legibility may be assured without necessarily increasing the cost of the drawing. My early experience of six years in a drafting-room leads me to appreciate the importance of many hints which might otherwise appear to be of little, it any, value.* Each of the chapters on 'Outline Shading," and on "Section Lining,' are alone worth the price of the book." —Prof. Henry S. Jacoby, Cornell University, The Engineering News Publishing Co., 220 Broadway, New YorR
