My invention relates to improvementsin lever and ratchet mechanism for actuating 4 cars, m constructionbeing more especially 'theshaft carrying the central rollers for imapplica 1e to what are ordinarily known as parting the initial lateral movement to the push cars. v um mg body. Fig. 6 is a central view of A The object of the invention, is to provide the" ower. portion of the brake-operating 75 a construction ofthis class which ma be lever. Fig.7 is a detail view of one ofthe tilted to a lateral position on either si e of rollers, "of smaller diameter mounted on the the car for either oading or dumping purplatform'of thecar. v v poses. y The same reference characters indicate the IB virtue of my improved construction, sarhe parts in all the views. so a relatively stationary platform equip ed 6 the axles; and 7 the framework of the car with rollers, the central roller or a num er provided with a platform 8. Extending of rollers in alinement being-of considerable transversely across this platform are two end greater diameter than the rollers of the lates 9 and two intermediate plates low 35 outer edge of the car. The said body how- I hese plates 9 andlO are provided with cenever, is provided at its bottom with blocks tral bearings 12 in which is journaled a Ionwhich w en the body of thecaris in its 1101'- gitudinally disposed shaft 13 carryin% a -mal position, engage thei rollers of lesser number-of axially alined rollers, 14. he,

'eter than the "rollers 14. The body 22 of the said rollers will be sufficient toshift the car car, however, is provided at its outer edges withshort blocks 23 which engage the rollers 20 and support the car body in a horizontal position, the said blocks compensating for the dlfi'ere'nce in diameter between the con tral rolls 14; and the rolls at the outer edges of the platform. This body part of the car i i .iscentrally provided with two pairs of angle plates 24 and 25, the said plates being socured to the bottom of the car in such a man ner that they form keepers extending in opposite directions and. open at, their outer extremities to catch upon hinge pins 26 mounted at the ex'tremitiesof the transverse plates 10 and in the path of the said keepers when the body of thecar is shifted laterally in either.d1rection. When shifted toward one edge of thecar, the two keepers having their 0 en extremities ointin in one direction in the one direction orthe other according to the rotation of the rollers, whereby it is given its initial lateral movement causing its supporting blocks to leave the rollers 20, whereby it; is caused to tilt and automatically assume :the position shown in Fig. 2.

The body of the car is provided with sides 27 hing d at 28 and normally locked in the closed or upright position by spring catches 29'.

'Myimproved car is provided with suitable brake mechanism best illustrated in Fig. 4 in which the numeral 30 designates a lever centrally fulcrumed' on the lower surface of the bottom of the platform as shown at 31, its opposite extremities being equipped with brake shoes 32. Near each extremity of this lever is connected a rod 33 to whose outer extremity is connected alever 34 as shown at 35. 'Thislever is fulcrumed as shown at 36,

its arm above the fulcrum being provided will :with asocket'37 adapted to receive an operating handle 38. There is one of these levers at each end of the car and. the brakes may be applied from each end in a manner that e readily understood;

From the foregoing description the use and operation of my nnpi oved push car will be readil understood. Assuming that the body of t e car is in the normal position as shown b full lines in Fig. 1 and by dotted lines in *ig. 2, ifit is desired to cause the bod to assume the dumping position, the she t 15 is rotated sutliciently to .disengage ing normally the supporting blocks 23 from the rollers 20,

whereby the said body will slide automatically to the position shown in full lines in Fig. 2. This is the dumping position of t 10 car, and it is also the position in whicht e car may be loaded if desired. When the car is in this posit-ion it'is easily returned to the platform, since it is centrally hinged whereby its opposite'sides are equally balanced.

The end plates 9 are provided with upwardly pro]ecting flanges 9" which constitute retainingdeviees and also serve as guides for the body 22 of the car.

Having thus described my invention, what I- claim is i 1. A car having a latform whose central portion and outer e ges are provided with longitudinally alined rollers, the central rollers being of greater diameter than the edge rollers for the purpose set forth. 2. A car whose platform is provided with a number of centrally located longitudinally alined rollers, the o posite edges of the car being also provide with rollers of less diameter than the central rollers, and a body laterally movable on the platform, the central portion of the said body being adapted to rest upon the central rollers when the said body is in its normal position, the outer edges of the body 'being provided with blocks adapted to en age the rollers of lesser diameter, and suitable means for actuatin the centralrollers whereby an initial latera movement is imparted to the car body, substantially as described.

3. In a car, the combination with a platform provided with rollers of d'ifi'erent diameters, a body laterally movable on the rollers, the plat 'orm being provided with one hinge member and the body with another hin e member, the two members beseparate and distinct. from each other but located to be brought into operative relation when the body member is laterally shifted,substantially as described.

4. In a car of the class described, the combination with a platform, provided with a central roller, and an edge roller, a body restin upon the rollers and laterally movable, the edge roller being of less diameter than the central roller, and the body being provided with a block adapted to rest upon the roller of less diameter to compensate for the difierencc in size, the central roller be ing provided with a shaft. a lever loose on the shaft, and a ratchet and pawl connection between the lever and shaft whereby the central roller may be actuated to impart the initial lateral movement to the car body, substantially as described.

5. In a car of the class described, the combination with a platform, of a centrally locatcd longitudinally disposed rollerhiounted upon a shaft, the edge roller being mount ed at each edge of the car, a body mounted on the rollers and.- lolterally movable in both movable on the rollers between the said gireetions, the outer edges of the platform flanges which constitute retaining devices d the central portion ofthe body" being and form guides for the body during its provided with cooperating hinge members lateral movement. 15-
