T o4 all whom t may concern:

' Beit knownthat I, ARCHIBALD H. EHLE, acitizenof the United States, lresiding in Philadel ia, Pennsylvania, have invented 5 certain mprovements in Internal-Combustion Locomotives, ofwhich the following is a secifcation. l

4he object of my invention -is'. to constructv a simple and practical locomotve'using an internal combustion engine 'as the motive' power and gearinA through which the wheels are driven, toget er with reverse gearing Wherebythe locomotive can be driven infone direction at thes'ame number of speeds as 1, is a sideV view illustrating my inte'rnal combustion locomotive; Fig. 2, is a plan view; F 3, is a. sectional plan view 0n the' line 3--3, Fig. l F ig. 4, is a front View, and. Fig. 5, is a view illustrating a modification of the driving mechanism.

v'A is .the frame of the locomotive having' pedestals vinfwhich are boxes w-a. B-B Vare axles mounted in the boxes and; on which'are 'the llangedvvheelsb-b.I ,respectively. In the present instance the wheels are 'mounted on the. inside of the; frame and the axles `project beyond the frame and-on each axle is a crank c; the two` cranks at each -side being connectedbya rod" v C, asclearlyillustrated in' Fig?. Thiscon-j struction A1s particularly adapted for narrow.

Agage tracks, but in wide{.gage^ tracks'the in whichcase the crank vpins are secured di- "between boxes a. anelitheframe are-coiled 3" rings y -in the'prese'nt instance,v sc .that {ti-ft z frame"is spring su ported. y 'D is an internal com ust-ion engine, of-any suitable {.type, having cylinders d, vWater- 'acketed,'aa shown, and 'Umain crank shaft on whichi's mounted the Hy wheel D2.

is provided w1th,a, clutch ;E, which is arranged to be moved into engagement with a v'clutch face, in the present instance on the fly wheel D2. The shaft E vis connected 60. through a flexible. joint in turn to a shaft E?, which has its bearings in the gear casing 5F. SeCuredto't-his shaft are two gear pinion's e and e',one greater in diameter thanv the "other, and these pinions mesh respectively' vturn with the main shaft.

Athe shaft G remains idle.

the bevel tgear wheels HQI-I. hisl sleeveis l splined to'the shaftA I so that. `while it is free- 'inclosed vvithin `the casing.

the ax wheels and chain on the opposite side of the tou A is th motive und in front of the seat is the brake ,wheel J, mounted on a shaft J connected with wheels f-f, mounted loosely on an in- 55 termediate shaft G so that t-he gears always 0n the 4intermediate 'shaft G is a clutch sleeve g.` Thisv clutch sleeve is connectedto the shaft .so that whileit is free to slide thereon' it must turn with the shaft. each end of this sleeve are clutch teeth which engage the Aclutch teeth lo n the hubs' of the gear wheels f-f, and when'the sleeve. is in the mid position Vhen the clutch sleeve is moved to the rear then the shaft G is driven through the gears e and f. 4Then the clutch is moved forward the shaft iis driven through the gears e'- and f'. -The bearings, in the present instance, for, the sha'ts'Ef and G are hall bearings and I 'preferably extend the hubs of the gears f the hubs of the said wheels. y

On the forward end of thc'shaitz G is a (beveled pinion g', which meshs'drivith bevel wheels IIs-H on a transverse, shaft I.

.These Wheels are loosely mountedon the shaft-so `that when the, shaft is turned the wheelsHand H' revolve. On the shaft I andmounted between the two wheels H and H".'is' a" clutch sleeve Il, hav'ng teeth fat each end which engage the teetiion the hubs of to slide on the shaft-f, itv must turn with it'. The shaft I has its hearings in an extension F of theg'ear casing so that the gearing'is 90 On one end of the shaft I'outside.v of the'A gear casing'is :1 sprocket wheel i and pass- 111g throughihis sprocket wheel is a 'chain' i?. which B so vthat the ront nx'le is .driven'qt throu the gearing and the drive chain.. *In` some mstances,-I may duplicate the chain drive by mounting another -pnir of sprocket casin f e cab of the locomotive having, in* the presentinstance, a seat a. for the engine driver and the engine driver in thisinstan facestivard. the opposite'sidc of the 10Goi' to brake mechanism J 2 ofthe ordinary and carried by the supports jforthis 'sha f t lpasses around a "s rocket wheel-2'?, 'f' .A

is a throttle'lever Kl and a spark lever L.

The Ineens of connecting these levers with i the enginey is of theordinary type and need not be described in detail;

N ifsfthe'ispeed control lever which shiftsV the chitch'. sleeveA g, while "M is the reverse control lever which shifts the clutch sleeve I.4 BothV o'fthese levers are'located sowas to be readily. operated fby the engine driver from his seat. l 4

P is the foot-treadle which is connected by a wirerope or chain p under tension to the clutch lever ofthe main clutch E so that when it is neessary to throw ont the main clutch., the treadle P is depressed.

The speed control lever N is mounted on a vertical shaft N on which is an arm a at4 taclied to' along connecting rod a leading' to anv arm a2 on the rock shaft Gr carrying a forked arm g2 which engages the. sleeve g so that when the speed controlled lever N is moved motion will be imparted to the sleeve G. The reverse control lever M is mounted on a rocksh'aft M which extends to the forward end of the frame and on this shaft' v is an arm ml connected by a link m ,toen -larm m2 on a shaft carrying a forked arm'v gine.

Projectingfroin the forward end of the cab i is la hood Az which incloses theengine.

The number of speeds forward and rear# Ward will depend uponthe purpose Afor which' the locomotive is intended."

By the above construction, 'it will be seen that I ain-enabledto provide for two' or more changes of speed forward and two or-v more corresponding changes of speed? roarward willbe understood that this locomotive 'is especially adapted for shifting-in' industrial works andas the locomotive will travel in either ,direction the` Vsaine number of speeds `is necessary in goingfliackward as 1n, going forward. i

The Vlocation Mof the seat of the driver is such that he has full view of the track in going in either direction and all the' operating mechanism is within easy reach, gw

ing him absolute control of the locomotive. I claim: 1. The combination in an internal combustion locomotive, ofa main frame; two axles mounted on said frame; wheels on the axles; cranks on the axles; rods connecting' fthe cranks; an internal combustion engine mounted on the 'frame 'over the rear axle; a primary driving shaft extending'from the crank axle of the engine over the forward` axle ofy the locomotive; an intermediate shaft located in advance of the forward axle and below the main driving shaft;v change gearing vrn ounted between the two shafts "a'bevel f pinionl on the end of the intermediate shaft; a transverse shaft; a bevel gear wheel 'thereon withwhich the pinion meshes; a chain wheel. on the forward axle of the locomotive; a chain wheel on the transverse shaft; and

va chainpassing around the chain wheels.

' 2. The combination in an internal .Goinbustio'n locomotve,' of a mainframe; two

axles mounted thereon; wheels on the axles;

cranksl also onlthe axles; connecting rods extending from oneJ crank to theother on eachside ofthe locomotive; aninternal combustion engine mounted on the frame above the rear axle; a mainv shaft coupled to the crank shaft of the engine and extending overtthe front axle.; an intermediate shaft located in advanceof the front a-x'le and located below the main shaft; change gearing coupling the two shafts; a bevel pinion on the end of the intermediate shaft; a transverse shaft, at the forward end of the loco-
