Specification of Letters Patent.

Patented Dec. 5, 191-1.

Application filed January 25, 1911. Serial No. 604,564.

7 To all whom it may concern:

Be it known thatl, Hanan B. Bown, a citizen of the United States, residing at Wilmington, in the-county of Newcastle and State of Delaware, have invented certain new and useful Improvements" in Smoke- 1 "Qonsumers, of which the following is a Specification, reference being had therein to the accompanying drawing.

This invention relates, in its broad idea,-. to a smoke consumer for use particularly in locomotives; although it maybe employed with equal advantage in the fire boxes of air mixing with the gases stationary or marine boilers. I

It is a well knowniiact that smoke is caused by poor cpr'nbustion and insufiicient from the burning fuel.

While I- am aware that numerous devices have been employed with some success for supplying a greater amount of air to the fire box than is introduced therein by a natural draft; these devices, as a rule, have been faulty in that, being subjected to the intense heatof thefire box,-they becorne burned out and useless within a short time;

face of the fire box.

' cheap, durable and efiicient; and easily in-' I vide a device and also they detract from the heating sur- My present invention to a novel construction and application of air jet pipes, or nozzles, and operating means for introducing a supply of heated air into the firebox to mix with the gases to produce a more perfect combustiomand thus consume the smoke. I

The objects of'the invention are to provide an airpipe or nozzle, that shall be stalled in the fire box of any boiler, either locomotive, marine or stationary.

Another object of the invention is to proof this class that shall be easily operated, and that is so constructed that it will withstand the heat to which it is subjected With these and other objects in view, my invent-ion consists in, certain construction and combination of parts as will hereinafter be fully; described and claimed and illustrated in the accompanying drawings, which form a part of this application, and in which like figures of reference refer to. corresponding parts in all of the views; but it is fully understood that while I have described my invention as shown in the drawrelate's particularly ings, that I do not confine myself to the exact design, as slight changes may be made in the construction and arrangement of the several parts without departing from the spirit of the invention, y

In the drawings :-Figure 1, is a front view of the device, showing the same in stalled in the fire box of a locomotive. Fig.

is a top plan view of the same. Fig. 4-, is a detail "ertical sectional view of the nozzle, and illustrates the method of securing the same to the rear wall of the fire box.

Referring to the drawings, my device I comprises a'double walledair nozzle 1, of iron or steel, or other suitable material,-

which is formed with the curved discharge end 2, having an elongated discharge opening 3, therein of the proper form to.properly distribute the air throughout the fire box. Said air nozzle 1, is also formed with the hollow bosses 4:, extending at rightangles from the rear thereof; and the ducts 5, in said bosses communicating with the water chamber 6,,tormed by the double walls of said nozzle 1. Said air nozzles 1, arepreferablyplaced in the two rear cor ners of the fire box 7, and are shown as'attached thereto in the following way although they may be secured in any suitable manner.. comprises the plates 8, and 9, which are spaced apart and form the water leg'lO; while-at suitable places, said plates 8, and

andwithin said tubes 11, are inserted the 2, is a side elevation of the same. Fig. 3,

The rear wall of the fire box .7,

bosses 4, of the air nozzle 1, which are held therein by the nut 12, threaded 'thereon a and by this method of mounting the air nozzle 1, no provision has'to be made -for expansion andcontraction in" the Water pipes, as they are all-without the fire box 7 I Said bosses 4, are provided with the inter-- nalscrew-threads 13, b which are secured the water pipes 14, whlch'havetheir other ends tapped into the outer late 8;and in this manner, a circulationo water is main-" tained through the water chamber or jacket 6, from the water he 10, ofthe boiler; said water pipes i l, being supplied with the' cut off valves 15, for the purposeiof preventing the water entering the fire box, if one of the air broken. There is alsoprovided a flushing valve 16, placed in the lower pipe 14, be-

nozzle's 1,. should become tween the valve 15, and the nozzle 1, for Ighe purpose of cleaning outsaid water cham- The lower end 17, of the air nozzle 1, is reduced in diameter below the lower end of the water chamber 6, and extends downward through the grate 18, and is connected by a T-fitting 19, to an air pipe 20; said air pipe 20, connects together both of the air nozzles 1, and has secured to each end, a curved intake air pipe 21, which extends from the side of the locomotive, and is fitted with a netted intake funnel 22, on the end thereof, in such a manner, that while the locomotive is in motion, suflicient air will enter the intake funnels 22, to discharge from the nozzles 1, into the fire box; the air being heated as it passes through the nozzles 1, by the heat therefrom. To produce the same result and supply the air .tor the nozzles, while the locomotive is standing still, an air pipe 23, is attached to the air pipe 20, running from the usual force draft pipe from the power blower (not shown). Also for starting a circulation of air through the nozzle 1, a steam jet pipe 24, is attached to the T-fittings 19; the admission of steam being controlled by a valve 25.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is In a smoke consumer of the class described, the combination with a fire box having a water-leg, and air inlet and'supply pipes leading to said fire box, and an air discharge nozzle mounted in said fire box and connected to said air supply pipes, said air discharge nozzle formed with a water jacket, of hollow bosses integral with and extending from said air discharge nozzle through the wall of said fire box, and

means for connecting said hollow bosses to the water leg of said fire box.

In testimony whereof I affix my signature in presence of two Witnesses.
