SELF-PROPELLED RAIL OAR.

Application filed October 13, 1924. Serial No. 743,242.

The present improvements, relating, as indicated, to self propelled rail cars, have more particular regard to cars designed for in dustrial use as for the haulage of materials 6 about plants, mines and the like. It will be understood, however, that the novel features of construction presented may be employed in rail cars of other types and designed for widely different uses.

One principal object of the invention is to provide a self propelled rail car in which the motivepower is derived from an internal combustion (gas or oil) engine. Another object is to support such engine with accessory operating elements, as well as necessary control and operating elements for the car proper, on a truck frame that is capable of swiveling independently of the main frame of the car proper. To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly ointed out in the claims, the annexed drawings and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used. y

In said annexed drawings Fig. 1 is a side elevation of a self propelled rail car embodying my present improvements; Fig. 2 is a broken plan view of the same; Fig. 3 is a rear elevation thereof, 5 the car being viewed from the left as shown in Fig. 1; and Fig. 1 is a broken transverse section taken on the plane indicated by the lines 4- 1, Figs. 1 and 2.

The particular type of car illustrated in 0 the drawin s is an ore transfer car such as used about blast furnaces for hauling ore or other materials from one point to another. The car is accordingly provided with a hopper body 1, the lower portions of the sides whereof slope inwardly so thatthe material may be discharged on either side of the oppositely sloping bottom 2 by opening one or the other of the higed gates 3. Two sets of toggles 1, each 0 erated by means of a pressure. fluid cylinclbr 5 with piston (not shown), are provided for opening the gates 3 or retaining them closed as desired. Such operating cylinders and pistons, as shown in Fig. 1, are preferably located at one end of 56 the car body 1 and adjacent thereto air tanks 6 are carried in the framework 7 that supports the corresponding end of the body.

Such body and framework 7 are built upon a main frame 8 of more or less standard construction, the principal members composing such frame being two longitudinal beams or sills 9, one on each side, which extend to the right far enough to have swiveled support upon a standard car truck 10. At the opposite end the beams 9 project similarly beyond the corresponding end of the body 1 and are united at their ends by a cross beam or bolster 12. The latter is centrally supported by a swiveled mounting 13, preferably provided with anti-friction rollers on a truck 14 of special design. This truck is in effect an independent tractor unit, being provided with a platform 15 that lies above and clear of the cross-beam or bolster 12 and serves as a support for the engine by which the truck and thus the car are propelled. Such engine is housed within a hood 16, similar to that regularly employed in motor trucks, and to the rear of such hood is located a cab 17 for the operator.

As best shown in Fig. e

1, the portions 1 1 of the side-frame mem rs composing truck 14, that lie intermediate of the axles 18 are dropped below the ends of said members and so provide ample space for any oscillation of the bolster 12 relatively to the truck. The truck springs 19, it will be noted, are interposed between the journals of the axles and the portions of such side-frame members in which such axles are held. The latter are thus permitted necessary independent vertical movement in passing over an uneven track.

The one side of cab 17, as best shown in Fig. 2, is olfset with respect to the center line so as to provide clear vision forward and back for the operator, the seat 20 which is located adjacent this side being reversible in position, as indicated in dottedoutline, and the cab where thus extending beyond the platform and over the beam or sill 9, sets sufficiently above to afford clearance. The fuel tank 21 is preferably located between the hood 16 and cab 17, as is also an air compressor 22, while all the elements for controlling the operation of the engine are located in the cab 17 conveniently within the reach of the operator when occupying seat 20. As shown, such elements include a J to;

clutch pedal23, gas throttle 24L, brake valve 25 and spark'leveri26, together with a gear shift lever 27 In addition to the control devices for the engine and motor truck 14,

r The driving connecti 'wheels on the rails.

there are. alsoblocated in thecab, adjacent the operators. seat, valves 29 for contro-l- 1 ling the operation of the gates 3 Where a hopper body of the type described is em' plyedfand valves 30 for operating the usual sanding devices to prevent slipping of the ons bet Ween the Yengine and thefvvheels 31? are preferably of the sprocket cliain"type,,one such chain 32 connecting a, transverse shaftfig on' plat formf15 with thexrear wheels SLof' said truck and another chain 34 connecting such rear Wheels ,vviththe forward; heels; It

willbe understoodthatsaid transverse shaft- 33" isadriven from the engine through a transmission gear of} standard construction;
