Description

Y reference being i" pmvideil to prevent HARRY A. HOKE, OF ALTOONA, PBNZQISYLVANTB LOCOMOTIVE SMOKE-LETER.

Specication of Letters Patent.

Yatented Mar. 9, 1915.

Application ined January Q, 1914. Serial No. 809,819.

To all whom 'it may concern: i rlie it known that l, HARRY A. HOKE, a citizen of the United States oi America, residing in Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful improvements in Locomotive Smoke-Lfters, of which the following is a true and exact description, had to the accompanying drawings, which form a part thereof.

My present invention relates to railway locomotives, and has tor rits object to provide simple and effective means for lifting the. smolre issuing 4from the smolrestack of a locomotive sutiicientlyY high above the locomotive to prevent it from obscuring the engine crew's view along the right ot way.

lily invention is devised to overcome a rather serious dilliculti1 which has been eX- perienccd with modern locomotives. lu such a locomotive the smoltestaclr itself, cannot project much above the top of the boiler proper on account ot the size of the latter, and because otthis fact, and the long length ol3 the boiler, the smoke issuing from the sinolrestaclr not carried high enough at times to prevent it enveloping the locomotive cab. thereby making it difficult or impossible tor the engine crew to .distinguish nais or other objects along the right ot way.

The various Jfeatures ot novelty which characterize nii' invention are pointed out with particularity in the claims annexed to and forming a piart ot this speciiication. l? or a better understanding o'tY the invention, however, aud of' the advantages possessed bv it, reference should bc had to the accomiiilinving drawings and descriptive matter, in which 'l have illustrated and described one torni in which my invention may be cmbodied,

it the, drawings: Figure l is an elevation, partlyl in section, ot' a locomotive equipped with my invention; lig. l is an enlarged plan view ot' a portion oi' the top ot the siuohestacl; ot' the locomotive shown in l? i O. l; and F f3 is a section on the line ol Fig.

ln the drawings, l represents the locomotive` and il the smoke box at the front end ol the locomotive. (l represents the usual exhaust nozzle, discharging upwz .'dly into ih smoke box, and ll represents the screen the passage ot cinders into the smolrestaclr E. As shown, a ring blower D is mounted on top of the exhaust nozzle C, and is supplied with live steam at times when the engine is at rest or drifting to create the desired draft, and, under' some conditions, may be'operated when the engine is working to supplement the action of the exhaust, discharged through the noznle C, on the draft.

The smoltestacl E, as shown, is formed with a iianged portion E fitting against the boiler shell and a portion E2 extending into the boiler and terminating somewhat above thc exhaust nozzle C. At its upper end the stach E is formed with a hollow' bead. From the annular passage E in 'the hollow bead lead upwardly directed passages E4 which are inwardly inclined toward the axis oit' the sinolestaclr. Live steam is supplied to the passage ll:i through the pipes .F and ll from the steam dome A2 ot' the locoino tive. The tlow of steam through the pipe ll is controlled by the valve G located in the locomotive cab A3, and a valve l is ,shown yas located in the locomotive cab to control the passage of steam through the pipes :indd to the blower i3.

ln the use ol my invention steam isi/supi plied to the annular passage E3 atthe top of the smokestack whenever this is necessary or desirable to prevent the smoke from obscuring the engine crews vision along the right of way. iVhen steam is thus supplied to the passage E3, the jets of steam issuing from the upwardly directed and inwardly inclined nozzle passages Ff* impinge against the gaseous products issuing from the smokestack in such manner as to carry these products well above the locomotive. lt is to be observed that these jets olt steam do not interfere with, but, on the contrary, directly augment the action ot' the other agencies tending to create a drait through the smokestacli; and that the means for produc-- ing these jets are so disposed that they do not interfere with the iree liowA of the gaseous products through the smokestaclr.

Having now described my invention, what l claim as new andA desire to secure by Letters Patent, is:

1. ln a locomotive, the combination-with the locomotiv e smolrestaclr of means for discharging steam at the top of said stack in upwardly and inwardly directed jets disposed around the circumference of the stack 110 at the top thereof adapted to' lift the smoke issuing from the stach well above the upper end of the latter.

end with a chamber surrounding the passageway for smoke, and with nozzle passages leading upwardly and inwardly therefrom so that steam supplied to said chamber will issue from said passages in jets impinging against and lifting the body of gaseous products issuing from the smokestacl well above the upper end of the latter, and means for supplying steam to said chamber from the locomotive boiler lcomprising piping and a controlling valve located in the locomotive cab.

3. In a locomotive, the combination with the locomotive smokestack provided at its upper end with a chamber surrounding the I passageway for smoke and wili a plurality of small size nozzle passages leading upwardly and inwardly therefrom, and inclined toward the stack axis so that steam said chamber will issue from jets impinging against and lifting the body of gaseous products issuing from the smokestack well above the upper" end of the f" liter, and means for supplying steam to said chamber from the locomot've boiler comprising piping and a controlling valve located in the locomotive cab.

4f. ln a locomotive, the combination of a locomotive stack provided at its upper rim with an annular steam chamber surrounding theA smoke passage through the stack and having a series of small orifices so directed that steam jets issuing theref om will focus at a point in the axis of the stack some distance above the top of the latter so that the body of gaseous products issuing1 from the smoke-stack will be lifted well above the upper end of the latter, and a steam pipe connecting said chamber to the boiler.

In a locmotive, the combination with the locomotive smokestach of means for discharging steam at the top of said stack in upwardly directed jets inwardly inclined somewhat toward the aXis of said stack and uniformly distributed jets being adapted from the stack the latter.

to lift the smoke issuing well above the upper end of l HARRY A. HOKE. Witnesses:
