represcntslhe steam control for the stcaiii pipe 1 and its extension 18, said lever 46 being"connected by a rodv 47 with. a valve 48 controlling the steam flow tial. The essential feature of the valve 48 is that it controls the lowfrom the pipe l t0 the pipe 18, or, in other words, controls the admission of steam to the rear cylinder 20' its companion on the opposite side. Thv details of steam admission to the forA Ward or locomotive cylindei' 49 and its companion are not shown, as this invention re- Yquires no change in the usual throttle and its .connections and a particular description of *this .as wellI as several other well known parts which are the usual parts of a locomotive structure require no description in this connection. The draw-bar couplingbetween locomotive and tender is represented at 5() and the pipe '29 is substantially the axis upon which the tender body is permitted to swing relative to the truck in rounding curves to the desirable slight extent. rl`he wheels 51, 52, and 54 of the tender are all shown as employed for traction purposes', hence these wheels together with the locomotive drivers 55, 56, and carry the entire weight of locomotive and its teider and the auxiliary gravity tanks 2 5 and 2G.,

In lieu of the usual forward truck one of the-functions of which is said to be to relieve the cylinders from a portion vof the initial blows or impacts that the forward wheels receive, I have placedthe cylinder 49'about six feet in the rear of its` usual position, or,

as .shown in Fig.

1, between the first and second drivers 55 and 5G which removes the i cyiindcr from the position of greatest strain g and substantially ma kes the driver 55 serve as the forward truck while also Servingas a traction Wheel.

cylinders. The weight of locomotive or.

. invention utilized by transferring the locothrough the pipe 4, the exact. details of which are non-esseninotive body projection beyond the drivers to the rear of the driver or drivers 57 and supporting the rearward projection upon the tender truck. The point of support of the rear of the engine on the tender isv indicated at 58 and is simply the usual pivotal bearing Y which is on the tender truck 21 the tenderbody 22 being, as previously explained', rev` oluble ielat-iveto the truck to a liinited extent on the axis represented by the pipe poi tion 29.

Having thus described my invention I claim as new and 'desire to Patentl. The combination with a locomotive and' supply is utilized as weight for the locoinotive :is specified. i?. 'l`lie combination with a locomotive of the .smoke box into which the boiler fines of secure by Letters the locomotive have their outlets at the front end of the locomotive, a,siibstaiitially sim- .ilai' smoke box at the rear end` of the locomotive boiler,v tlues connecting the front and rear smoke box, and an outlet or smoke stack for the latter.

3. The combination with a locomotive Q and its cylinder cocksT ot' means for exhaustfing through said cylinder cocks und the with the usual equipment of engine and ten- Y words, make the tender and its heavy weight serve as an auxiliary engine by. manipulating the lever 4t', to :admit steam `to the rear l smoke stack of said locomotive.
