Be it known that I, JAMES K. BooTi-I, of Greenville, Mercer county, Pennsylvania, have invented a new and useful Locomotive Exhaust-Nozzle, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 shows my exhaust-nozzle applied tothe front end of a locomotive, the parts of the latter being indicated by dotted lines. Fig. 2 is a plan View of the nozzle on a larger scale. III III of Fig. 2, and Fig. 4 is a modification.

The purpose of my invention is to provide an exhaust-nozzle for locomotives which shall be more eiiicient than the nozzles heretofore employed and will cause a regular and efficient distribution of steam into the stack, producing thereby better combustion of fuel and more uniform results.

My apparatus is simple in construction and is easily applied to any of the exhaust-boxes now in common use, so that it does not require reiitting ofthe engine in order to install it.

In the drawings, 2 represents the front tubevsheet of the locomotive, 3 is the smoke-box,

4 is the petticoat-pipe, and 5 is the stack.

6 is the exhaust-box, which may be of any usual or suitable construction, and 7 is the nozzle of my invention, which I apply to this box. This nozzle consists of a casting comprising two concentric portions b c, circular in cross-section in order to conform to the usual shape of the top of the exhaust-box 6. The part L is annular in form, so as to iit within the mouth of the exhaust-box, and has a flange CZ, which rests on top of the box. The central concentric portion c is conoidal in form, the apex being directed downwardly, so that it affords an annular tapering passage leading from theinterior of the exhaust-box to the top thereof. The parts Z; and c are held together by integral cross-pieces e. The nozzle thus affords an annular outlet for the steam Fig. 3 is a vertical section on the line,

coming from the exhaust-box, and the conical portion o acts as a delector to distribute and deiieet the exhaust-steam and to deliver itregularly in the most eliicient manner into the petticoat-pipe.

In the modiiication shown in Fig. 4 instead of adapting the part Z) to fit within the top of the exhaust-box 6 I arrange it to extend above the same and apply the nozzle to the exhaustbox by means of a circular collar f, which fits around the exterior of the exhaust-box.

In Fig. l I show the exhaust-box 6 divided at the lower portion with a partition 8, separating the exhaust from the two cylinders of the engine; but this, though desirable, is not essential to my invention.

rThe size of the annular opening of the exhaust may be changed to suit the particular purpose to which it is to be applied. The nozzle can be made of from fifteen to twentyfour pounds in weight, so that it is cheap to manufacture and easy to apply. Its use results in a saving of fuel and in a reduction of the back pressure of the exhaust.

Within the scope of my invention as defined in the claim modifications may be made by those skilled in the art, since What I claim is- An exhaust-nozzle comprising an annular nozzle part adapted to be iitted to the top of an exhaust-box, the walls of said part converging to the top, a central cone of conoidal form within the nozzle and having its apex below the top thereof and forming an annular exhaust-passage gradually and continuously converging toward the top, and cross-pieces connecting the nozzle and central cone, the said parts being' integ'ral with each other, substantially as described.

In testimony whereof I have hereunto set my hand.

JAMES K. BOOTH.
