W e claim .as our invention:

l. The combination, with a traction machine iframe, of an engine having bearings in said machineilrame concentric with the crank shaft oit the engine, one of said bear-4 ings comprising a plate secured to the engine frame and acasting mounted on the machine vframe and having a peripheral bearing tor said plate, and meansfor locking said casing and .said plate together, said lockingA means, kwhen released, allowing said engine frame to be tilted to one side oi the .machine frame for exposing the working parts thereof, y

2. The combination, with a traction ma y chine frame and a gear casing secured thereto, ot a housing secured. to said gear case and provided with a iianged peripheral edge,

an engine frame having a bearing at one endv on the peripheral edge of said housing for rotation4 thereon when said engine frame is released, means for normally clamping said' bearing and said housing together, and a bearing on said machine trame for the oppositey end ot" the engine l'raine.

A traction machine comprising a Yframe having upper and lower rails, and an engine Frame supported between said rails, said engine rraiiiebeing mounted to tilt to either side of said machine :trame to expose its vworking parts, and means for locking said enginel Ytrame in an upright position between said upper and lower rails..

4t. il tract ,i comirisinsi' a frame 1 .l c i E having upperl is, an engine iraine mounted in bca 5. A. traction machine comprising a vframev having upper and lower rails, an engine frame'journaled at its forward end in the lower portion of said machine trame, a

housing mounted between the upper and` lower rails of .said machine trame and hav` ing a 'hanged peripheral edge, a member secured to said engine traine and having a seat to receive said peripheral edge and on t which seat said member'is adapted toslide, when said engine frame is tilted in either" direction, and means tor locking said menibe'r and said peripheral edge together.

6.v r)The combination, witha traction inachine trame having upper and lower rails,

of a housing mounted therein, an engine trame lseated in said housing for rotation thereon, a bearing for the opposite end `ot the engine frame concentric with said housing/hearing, bolts mounted in said housingy and having means Yfor clamping the bearing'u of said engine and said housing together,

v.said bolts when released allowing freedom of tilting` of vsaid engine traine in either direction.

7. VThe combination, with a tractiony ina-I chine rame having upper and lower rails, of a housing mounted therein, an engine frame seated in said housing` for 'rotation thereon, a bearing `for the oppositeend ot the engine frame concentric with said housing, bearing bolts mounted in said housing fioo and having means for clamping the bearing oit` said engine and housing together, said bolts whenreleased allowino` said engine trame to tilt` laterally lin either direction and compressionsprings mounted on said bolts lor takingup thev shock or jar on the engine 'traine resulting from thel lurching ot said machine trame.

A traction machine coniprisinga traine, a rear axle mounted therein' and traction wheels for said axle, an engine traine mounted in said tra-me with its crank shaft eX- tending longitudinally thereof, said eiig'gine trampJ having `'forward and rear bearings concentric with said crank shattand a driving 'connection between said engine trame and said traction wheels, means for temporarily securing said engine trame in an up right working position in said machine iai frame, said securing ineensx when released, allowing sei@ engine frame o tilt iateiaily, for the purpose specified.

9. .The Vonibination, with e traction machine freine of greater dept-h than width, of :in en. 'freine inountew'- "lengthwise of seid inetion machine freine and having bezu'iiigs for esciiietion of seid engine frame to one Ysiii@ e'f seid traction `freine Lo expose the working parts of the engine7 and ineens severing said engine frame in its Working position.

i0. The .foznbinatioin with. e traction Inachine 'fname of an engine 'freine mounted ieigiudinelly thereof, and having beerings on which snif?. engine freine is adapted e oseiiiee on either side io expose the vfoi ng parts of the engine. en eens for locking seid engine oseille 1l.
