The most notable increase in their application, however, has been in connection with heating apparatus for heating buildings and drying all kinds of material. They are equally as adaptable to furnaces of the various types, as to indirect radiators, steam coils or hot blast apparatus. Another application which engineers have recently begun to appreciate, on account of the greater econonn- and absolute certainty of results, is the emplo)'- ment of Fans to assist the draft in ventilating shafts or eduction flues in large public buildings. For years it has been customary to ))ut large stacks of coils into such shafts or flues to heat them and produce the required draft. The advantage of the Fan for this work is best .stated in the words of \V. 1 ’. Trowbridge, Trans. A. S. M. E. VII., 531, in a theoretical solution of the rela- live amounts of heat expended to remove a given volume of impure air by a Fan and by a Chiuine}^; “Assuming the total efficiency of a Fan to be only I/25, •w’hich is made up of an efficiency of i/io for the engine, 5 10 for the F'an itself, and 8,10 for efficiency as regards Friction, the Fan requires an expenditure of heat to drive it of only i 38 of the amount that would be required to produce the same venti¬ lation by a Chimney 100 feet high. For a Chimney 500 feet high, the Fan will be 7.6 times more efficient.’’ With an exjjerience of over a score of years, we are eminently fitted to give advice on all possible applications. We wish to impress upon our customers—past or prospective—that we solicit the freest correspondence regarding all points in question, as our great¬ est desire is the success of each installation. This is best assured by previous experience and the probabilities are all in our favor that we have many times met with exactly the same conditions. AMERICAN BLOWER COMPANY 6 The A B Disc Ventilating Fan DESCRIPTION: A l-'aii totally dilTereiit in construction from any other fan on the market— built for the noiseless delivery of a maximnm volume of air with a minimum exjiense for power, and guaranteed, on actual test, to deliver from one-third to one-half more air with the same power than any other fan ever built. A Fan so constructed that it will not only exhaust air from a compartment and deliver into the open, but will deliver a practically undiminished volume against a pressure of from one to two ounces. A mechanism combining strength and rigidity with lightness and consequent ease of operation. CONSTRUCTION: Base —Made .solid and of cast-iron, a feature securing absolute freedom from vibration. Arms —Of cast-iron with a yoke in the centre to support the bearings. The ends of the arms are bolted to the fan casing and the base. Casing —Of sheet .steel, completely enclosing the fan blades, enabling the user to place in any position without danger of accident. Shaft —Of the finest quality of cold rolled steel. Journals —.As shown and described on page lo. Being self-oiling and self-aligning, they always run smooth and cool. These are better bearings than can be found in any other make of Disc Fan, and alone are worth more than the entire fan of common types. Blades and Central Discs —In these two features ►■I basis of our claim for large volume of air ^ ^ handled and delivery against pressure. In this Fan, there are 12 blades against 8 at the most — and usually 6—of any other fan. Each blade is made of steel, overlapping the one next to it, and is bolted to each of two large Centre Discs, one of which is on either side. This increased number of blades assures a proportionately greater delivery of air, and the extra support of the Discs, additional strength. Another, and even greater function of the Discs, is the prevention of a back-flow of air through the centre when working against pressure. 7 To illustrate the difference in this respect between the operation of the “ABC” Fan and one of the usual construction, let us assume that one of latter type is forcing; air into a long pipe or conduit. Its speed at the outside of the blades is high, and the propul¬ sive force great, but, as the centre is gradually approached, both of these factors rapidly decrease, until at the hub there is, of course, no such force, whatever, present ; in conse¬ quence, a circuit is set up much as shown in Fig. i, the 'result being that, after a certain pre.ssure has been estab¬ lished in the pipe, any additional sjieed will simply bring Fig- I air back through the centre. In the “A B C " Fan, such a thing is impossible. The propulsive force is much greater on account of the increased number of blades, and the wide Discs at the centre prevent any such back-flow at that jtoint, the result being, as shown by I'ig. 2, that the air having once ])assed through the Fan, has but one e.xit—the opposite end of the conduit. It is by virtue of these devices we are enabled to use a “ Disc ” Fan in many instances where other manufacturers employ the “ ]>addle-wheel ” type of I'an or “blower.” This is always desirable, when j)ossible, owing to the saving in power secured, as the “ Disc ” I'an requires but one-half to two-thirds that of the other tyjie to move the same volume of air. We are the only manufacturers who apply Disc I'ans to Hot Blast Apparatus for heating and drying. In many cases we are siiving large concerns sufficient in power to ])ay for the a])])a- ratus in the first year of its use. As extensive manufacturers of various tyjjes of Blowers and Steel Plate Fans of the “ j)addle-wheel “ type we make this statement, knowing whereof we speak, and certainly could not Pig ^2 afford to recommend it in place of the other types of fans unless it had the decided points of advantage claimed for it. We particularly call attention to our guarantee on pages 28 and 29. S The B Disc Ventilating Fan With Standard Base and Pulley.

They are lined with the finest qual¬ ity of Babbitt metal, and are in ever}- way the superior of any other Disc Fan bearing made. Fans smaller than 72" have sleeve boxes held in position with set screws instead of a pin bearing, as shown above. 10 The Disc Ventilating Fan With Cast-Iron Flanges. For Prices and Dimensions, see page 9. COMBINATIONS: On all sizes up to 72", the “A B C ” Disc Fans are provided with cast-iron bases, as shown on page 9; they will be furnished with cast-iron flanges, as shown above, when desired. Angle-iron flanges, as shown on page 12, are regularly provided on sizes 84" and larger, and will be furnished on any smaller sizes when ordered. The Horizontal Fan, as shown on page 13, is regularly built with cast-iron flanges; for these an angle-iron flange can be substituted if desired. The mountings shown on pages i6and 17 are especially designed for attach¬ ment to heater casings, for either belt drive or vertical engine connected direct to Fan shaft. On page 14 is shown the “ABC” Fan with direct attached engine of a new type. This combination has met with much favor on account of its com¬ pactness, neatness, absolute noiselessness at very high speeds, and economical consumption of steam. All sizes of regular Fans are kept in stock, also unassembled parts for all possible combinations, thus assuring quick shipments. 11 Diain. of Kan The Disc Ventilating Fan With Angle-Iron Flanges DIMENSIONS AND PRICE LIST Price Pulley 1 1 Diain. of Shaft Width of Case Revolutions per Minute Cap’ty in Cub.

Observing this point when ordering, will save running crossed belts. All the cuts in this Catalogue show left hand F'ans, which is our stand¬ ard, and which will be shipped unless we receive instructions to the contrary. To cool an overheated room, in which heat is generated, it requires a large volunie of air to reduce the temperature. A Fan too small to do the work is an absolute waste of money and a continual disappointment. When buying a Fan, get one large enough. It does not require as large a Fan to remove smoke, fumes, gases or steam, ordinarily, as it does to cool an apartment. that produces the effects which are Herewith we illustrate a common method employed in installing a Fan in a window. As the majority of F’ans are put into windows, the accom¬ panying sketch is in order. The drawing is so clear that explanation is unnecessary. If a Fan with double angle-iron flanges is to be built into a brick wall, give us the exact thickness of wall and flanges will be spaced accordingly. When ordering Fans with electric motors, give us the voltage. When ordering engines to drive I'ans, give the steam pressure and the distance Fan will be from boiler. When asking for advice as to the size of Fan to perform a certain dutv, give us explicit information regarding all conditions, together with a plan and section of the building, showing all windows, doors, stairways, ele¬ vator shafts and location of apparatus be overcome. 27 IMPORTANT vSome twenty years ago, when the science of pneumatics was in its infancy, and likewise the manufacture of Fans, manufacturers found it necessary to publish tables giving the capacities of their Fans at varying speeds. For reasons easih- to be imagined, but an3’thing but commendable, capacities entireU' fictitious were assigned, far exceeding actual performance under the most favorable conditions. These tables were published and the public system- aticalh- swindled thereb}-. Later manufacturers, fearing that if they reduced the deliver^-, unfavorable comparisons would be made against them, arranged their tables either on the same basis or a trifle higher; and so it has gone on down to the present time. It did not take long, however, for the public to become aware of the imposition, and it is a long time since anj’ confidence whatever has been jjlaced in such tables. To-daj' thev are a source of mirth and ridicule to the intelligent public. The table on the opposite page is the result of actual and careful tests. The deliveries quoted will be found lower than those in tables published in the catalogues of other houses; but we wish it understood that ~wc guarantee every tigure of either capacity or horse power to be absotutety correct. EXPLANATION The following example will serve to illustrate the wa\- in which the table is used: Take, for instance, a 42" Fan. Working with a free and unobstructed dis¬ charge, this Fan will deliver 11,541 cubic feet of air, producing a velocity of 1,200 feet, when running 280 revolutions per minute, and will require .550 H. P. for operation. When attached to a Heater composed of coils of the proper free area, in order to deliver the same amount of air and produce the same velocitj-, the Fan will have to run 453 revolutions per minute, requiring 1.64 H. P. for operation. 28 The Disc Ventilating Fan CAPACITIES, SPEEDS AND HORSE POWERS AIK ITY Veloc- IN KT. Size ■ 21 24 30 36 42 48 54 60 72 84 96 108 J20 PKR Mix, Cu.
