14f Gbtoznaw v so t at it has been necessary to switcher hausted through'a pipe 33 in a well knownv I The piston rod 25 carries cross- 4O at th' when the caris to be'ooupled in a train the means considerable switching and turning of the car will be avoided, since with this coupling and draft gear-it is unnecessary to have the car at the .end of the train, except when it is-to be dumped.-

Heretofore, cars dum ing at one end only have been used, and suc cars have not been equi ped with couplings at the dumping end turn these cars around considerably in order to get the dumping end at the right position. With this construction herein, it is possible to avoid all this switching and turning inasmich as the car can be coupled from either on 1 The upright side frames 1 each have a shelf 13 onwh ch" is mounted a bracket 14 having a horizontaltrack 15 on which trun nions 17 connected 'w-ith the car body 7, as by a yoke 18, roll. The brack-ets 14 also have racks 1 9 on which roll gears 20 keyed to the trunnions 17, so that as the body is moved lon itudin-ally of the car frame, it simultaneous y tilts. In order to actuate the car body, a power cylinder 23 is provided, having a piston 24 and 'a piston rod 25 connected by a strap 26 with one of the tr'unnions 17. As shown in Fig. 1, the car body is at its upright central osition and the iston 24 midway of the cy inder 23, and a our-way valve 31 admits pressure throu h one orthe other of pipes 27 or 28 to one si opens the other side to the exhaust. To move the car body the fluid pressure may be admitted by means of an i et 32 and is exmanner. v head 29 which straddles'one of the racks 19 and slides on a guideway 30 (F 4 As shown in Fig. 1, it will be observe d. that cylinder 23, having a length equal to the/total movement of the car body, may be so'long as to interfere with the dumping'of the car body t end, or require lengthening of the frame in order to attach the draftbar 8.

, In 'order to permit of shortening the car frame, and also decrease the weight, the mechanism shown in Fig. 2 may be used. In this figure, the arts other than those shown will be exactly e' his 1 save that theside frames-l at the cylinder end may be somefln'l ig. 2, the iston rod 25 is made'hollotg aiid has a cross ead 28 fixed thereto as in ,ml'. [Between the rod'25 and the strap 2% in .L igtks interposed a sup lementaiy 'additional'sn'ction of piston roo 35 having shoulders '36 out therein at adistance apart equal to the longitudinal distance the 'car body will move in going from its central position to its extreme outward position-in either direction. The end of'the rod 25 is threaded and carries. a nm 38 thereon." Mounted to'embrece the nut and toextend e of the piston and assess in the one or the other of the slots 36 is a divided collar 39 held by bolts 40., By releasing the bolts 40 and removing the collar 39, the piston rod 25 and the strap 26will be disconnected. if now steam or, air be admitted on the right side of the i'sto'n 24 in Fig. 2, it will be moved towards t e left with-v out moving the stra 26 or the rod 25. As

e rod 25 goes over the soon as the end of t left hand'shoulder 36 on the rod 35, the

piston 24 will be at or about the extreme left end of the cylinder and the collar 39 can be replaced, thereby again coupling the piston rod 25 and the rod 35, and making the piston rod longer than it was beforei If be now admitted behind the piston 25 at the left end of the cylinder, the car body will be moved and dumped towards the right end of the frame and can be brought back to central position by reversing the pressure. In order to dump to-the left the'piston rod will be 1 shortened' Fi 2 shows this condition in which the car ody will be dumped to the left when pressure is admitted: at the right end of the cylinder. The side frames are provided with stops 42 at the left end against which the trunnions 17 will similar stop l3 is provided on the left or cylinder end, on the sideopposite the cylinderto check the movement in that direction. At the same time that the trunnions l7 strike the stops 42 or 43, the lower side of the car body will rest on the endirame 6 as shown in dotted lines in Fig. 1, so that the car body will be positively stopped at separated oints to have the piston stri e the without tending end of the cylinder. In practice, suitable latches or mechanical locking devices may be used to hold the car body in upright position during transportation.

From the fore seen that a doub e end dumpmg car is'provided which may be mounted on a single truck, by reasonof its shortness between couplings, and which will not tend to be pulled off the track in oing around curves, as happens where the ame has too great an overang beyond the" wheels. Also, it is pos-. sible to construct short frame by reason of the underframe 2h body, and also supporting'the car bod -at. either end, in dumpedpositiorr. It will of course 'be understood that the dimensions of the frame and-side hi the ladle will be determined according to the requirements 'of actnal also order to permit the car body toclear.

Whilea motor is herein shown mounted on the frame for operating the car body, it is not to be understood that the'invention is limited to motor means for operating the car body inasmuch as manual devices canv be practice, and in some instances it may 'mounted on the frame herein described for operating the car body. Such operating depressuretending under the car necessary to flare the side frames in' strike, and a c v n I c oing description, it will be tron.

Various modifications and changes in the specific construction herein described may be made without departing from the scope of the invention.
