CAR-DUMPING MECHANISM.

Specification of Letters Patent.

Patented Oct. 8, 1.912.

Application led October 30, 1911. SeriaLNo. 657,691.

T o all whom it 'may concern:

Beit known that I, Kiln. lil. HANsnN, a subject of Germany, citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful lmprovement in Car-Dumping Wechanism; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to dump cars.

The object of my invention is to provide a dump car in which provision is made for allowing a larger travel than is ordinarily obtained of that side of the car opposite that to which the car is dumped, so that the car when dumped is brought closer to the ground and there is a greater angle of inclination in side dumping which greatly facilitates the discharge of the material from the car.

To these ends my invention comprises' the novel features hereinafter' set forth and claimed.

In the accompanying drawings Figure l is a side elevation of my improved dump car; Fig. 2 is a plan View, 'a portion of the car being removed; Fig. 8v is a cross section; and lFig. 4 a like view showing the car in dumping position.

Referring to the drawings, the numeral 2 designates a suitable car body with sides 3 which are removable or may be swung up out of the way when the contents are to be discharged from the car. The center-- sills at are formed of channel-bars of the usual construction, and engaging said center-sills are the trunnion castings 5 which rest upon the castings 6 and upon which said trunnions are adapted to rock when the car is tilted to one side or the other. The castings G have t-he central depression 7 to receivey the central portion S of the trunnion and said casting has the upwardly projecting side portions 9 which are engaged by the sides ofv the trunnion in dumping and prevent the trunnion from slipping from the support or casting G. The cast-ing G 1s carrled by the pedestal 10 which is carried on the sub-structure 11 which may be of any suitable construction. This sub-strucf ture l'l carries the cylinders 1Q and 13, said cylinders having the inlets 14 for the admission of air or other motive fluid to operate the same. Within the cylinders are the pistons 15 to which the rodsI or links 16 are secured. The upper ends of the piston 1G are connected to the crank-arms 1T. These crank-amis 17 are secured to theshaft 18 extending longitudinally of the ear. The arms 19 are likewise` seellred to the shafts 1S and said arms carry the sheave or rollers Q0. Chains 23 and 124-. are secured to the stationary brackets 25 at opposite sides thereof, and the other ends of said chains are connected to the car body, as at 20, said chains engaging the sheaves Q0. (`ables or other flexible cords may be employed.

In the operation of my invention, when it is desired to dump the car to the position indicated in Fig. 4, air is admitted to the cylinder 13 and the piston l5 is raised therein. The arm 1G will move the crank-arm 17, and said crank-arm being secured to the shaft 18 will rock said shaft and move the arm '19 downto the position indicated in Fig. 4:. This movement of the arm 19 will act to lower that side of the car, the car tilting on the trunnion-support 6. As the chain 24; is secu red to the bracket 25 and to the earbody, it is apparent that the lowering of the arm 19 will cause the sheave to travel along the chain to the position indicated in Fig. 4. lVhen the car is dumped in this manner the chain 23 at the opposite side will pull `on the arm 1.9 and more said arm up to a substantial vertical position at the same time rocking the shaft 1S and moving the piston 15 in the cylinder 12 down to the lower end of said cylinder. The chain Q3 thus provides the slack to compensate for a much larger travel on that side of the car and consequently a greater dumping angle is obtained, which increases the facility for discharging the material from the car. l `urthermore the chains 23 and 24 hold the car in position against accidental dumping, and l am enabled to dispense with the rigid lever connections with the car-body which do not permit of the same flexibility of movement as I obtain by the employment of the chains arranged in the manner set forth.

The most advantageous location for the securing of the chain to the car-body, is over or substantially over the sheave and the point of connection with the bracket should be located as close to the center of the rota tion of the dumping body as possible to get the best results. l do not, however,

confine myself to the exact location of these tion.'

points of connection, as they maybe. varied and still come within the scope of my inven- When the car is in the dumping position as indicated in Fig. 1, and it is desired to bring it back into its normal position,-air is admitted in the cylinder 12 and 4the piston therein is raised whereby the shaft 13 is rotated to lower the arm 19 to the positionindicated in Fig. 3 whereupon the car is brought around vto its horizontal position' andthe parts at the .opposite side also resunie their normal positions with the'chaink in position to'hold the cati` against accidental dumping..

By my invention, I 4provvide a dumping-` mechanism whichl is adapted for cars of great length, as lthe dumping act-ion takes place uniformly at allpoints. and any strain or twisting action is entirely obviated. What I claim is: f

1. Ina dump-car, the combination of the tilting car-body, an underframe supporting said tilting car-body, chains vconnected at one of their ends to the car-body and at their opposite ends to .the underframe, members movably engaging said chains, and mechanisin for operating said members to tiltsaid car-body.

2. In a dump-car, the combination` oi a tilting car-body, an underframe'supporting.

,lever arms, sheaves on said arms engaging said chains, and mechanism for moving said arms to ytilt said car.

4. In a dump-car, the combination of a tilting car-body, an underi'rame supporting same, chains connected at one of their ends vdump said car-body.

5. In a dump-car, the combination of a tilting'- body, an underframe supporting same, chains connected at one of their ends to said underframe and at their opposite "ends to the .car-body, pivo-tally mounted lever arms, sheaves on said arms engaging with said chain, a fluid operated cylinder, and connections between said arms and said cylinder for moving `the arms.

6.In a dump-car, the combination of a tilting car-body, an underframe supporting same, chains connected to said underframe and car-body, movable arms, sheaves on said arms engaging said chains, a shaft on which said arms are mounted, a fluid operated cylinder, and connections between said cylinder rock the same to raise and and said shaft to lower said arms.y Y

7. In a dump-car, the combination of a tilting car-body, an underframe supporting same, chains connected to said underframe and .car-bo`dy, arms, sheaves on said arms engaging said chain, a shaft on which said arms ,are mounted, crank-arms von said shaft, a fluid operated cylinderand connections between said crank arms and cylinder for operating said tirst named arms.

8. In a dumping car, the combination of a tilting car-body, an underframe su porting same, chains connected to said un erframe andthe car-body, movable arms, sheaves on said. arms engaging said chains, a fluid op erated. cylinder, connections between said' cylinder and said arms for operating same, two-or more of said arms being connected t'o operate simultaneously.

In testimony whereof, I the said KARL H. HANSEN have hereunto set my hand.
