CHARLES B. PETELER, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR COMPANY, OF MINNEAPOLIS, MINNESOTA, A CORPORATION TO KILGORE-PETELER OF MINNESOTA.

DUMPING-GAR;

Specification of Letters Patent.

Patented Sept. 17, 1907.

To all whom it may concern:

Be it known that 1, CHARLES B. PETELER of the United States, residin a citizen 1 at Minneapolis, Hermepin county, Minnesota, have invented certain new and useful Improvements in following is a full, clear, and exact descript Du mp-Oarsiof which the ion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to dump cars and has particular ranged to be raised when the body is tilted to the load.

The object of my invention is to provide a having movable side boards, with improved .automatical body when the latter is tilted and to swing I l l l l t l reference to dumpcars in which the side board is an i t i discharge 5 dump car means for ly raising the side boards above the car said side board into a plane substantially parallel with the floor of the car at such times to give maximum clearance for ,the discharge of material.

A further object is to provide a dump car w tolnatic side board raising device which may be manually operated to raise as before mentioned,

l r l ith an aui the side- J board above the car body when the latter is in upright position, in order that material may without raising it above the car side With-these objects in view, my the improvements in dump cars hereinafter and particularly pointed out in the claims.

boards.

be loaded therein invention consists in described reference to the accompanying drawings forming a part My invention will be more readily understood by I embodying my improvements; Fig. 2 is a plan view of one end of the car shown in Fig. 1; and Fig. tion showing the car in tilted or dumping pos 3 is an end elevaition Referring to the drawings, 1 indicates the car truck,

whereof 2 is the end beam, and 3-3, the

side sills.

The truck is mounted upon suitable running gear, as

the wheels 3.

4 indicates the coupler attached to the draft sills 5.

Upon the draft sills 5 are arranged a number of brackets 6, upon which the car body 7 is pivoted. The

preferred or bed 8,

The latter are secured to the car body by suitable means which constitute my improved device for automatically raising said side boards, as above mentioned, when the car is tilted to discharge the contents thereof.

Each of the two side boards of the car is equipped at both ends with my novel operating mechanisms. these are identical in construction and operation the scription of the devices attached to one side I suffice for all.

As de- JOZLICl will Secured to each end of the side board is an arm 14 rigidly connected thereto, being braced by a bar 12, which latter is riveted or bolted to the arm 14 as at 13. This forms a rigid frame or arm upon the end of the side board with the end of the arm 14 preferably projecting therebeyond. This rigid arm is pivoted, as at 15, to a long lever 16, pivoted at its inner end 17 to a suitable bracket 18 fastened upon the end board 9 of the car body. Pivoted to the lever 16, as at 16, is a fulcrum bar, support or prop 20, the lower end of which rests upon the side beam 3 of the truck when the car body is tilted. Suitable means are provided to maintain the lower end of the bar 20 in proper position, that is, in engagement with the side beam In the drawings I have illustrated, for this purpose a bar or lever 21 fastened at one end to the bar 20, as at 22, and pivoted to the car body at its opposite end. However I need not rely upon such a device, but may provide a socket suitably arranged upon the truck to receive the lower end of the bar 20. The side board lifting and turning device is completed by a link 25, connecting the end of the arm 1 1 with the bar 20 and therewith forming a toggle-lever.

The arms and levers, as described, are so proportioned that when the car is in upright position the side boards 10, which run from end to end of the car, are held tightly in place. The arms 14 and 16, being practically in a straight horizontal line, hold the sides firmly, no matter how great theinternal pressure from the load contained in the car, and the upward thrust of the bars 20 and of the links 25 upon the ends of the arms 14, provents the side from turning upon the pivots 15. HOW- ever, on account of the relation of the several arms and levers and the arrangement of their pivotal points, as soon as the car body begins to tilt, the device so operates as to throw the lower edge of the side board out wardly, thereby relieving, to a great extent, the friction of the load upon said side board.

When the car body is tilted, as shown in Fig. 3, the lower end of the props 20 rest upon the side sill 3 of the truck, which prevents further downward movement Of said props, while the bar 21 prevents displacement of the ends of the bars 20 upon said side sill. As the car is tilted, the end pivots 1'7 move outwardly and downwardly, following the arcs of circles of which the pivotal axis 6 of the car body is the center. This causes the lovers 16 to rock upon the pivots 16, throwing their outer ends upwardly. This increases the distance between the pivot points 15 and the lower ends of the links 25. Hence the links 25 and the arms 14 act as toggle levers to turn the side board 10 upon the pivots 15 until the board assumes a position substantially parallel with the floor of the car. When the car is righted, gravity, together with the upward and the inward swing of the pivots 17, returns the parts to normal positions as shown in Fig. 1. Chains 7 are provided to normally maintain the car in upright position. These are unhooked when the car is to be dumped.

When the material is being loaded into the car by hand, the side boards may be raised manually in order that the workmen may be saved the extra labor of raising the heavy material to the additional height necessary to toss the same over the side boards, To raise the side board it is but necessary to give the lower ends of the props or fulcrum bars 20 an outward and upward pull. This will raise the side board above the car in a manner similar to that just described, when the car is tilted;

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a dumping car, a truck, a car body adapted to be tilted thereon to discharge its load, and a side board for said car body, in combination with swinging supports for said side board, props pivoted at one end to respective swinging supports, and toggle levers, connecting said side board with said props; the whole so arranged as to increase the angle between said swinging supports and said props, when the car is tilted, thereby straightening'said toggle lovers to turn said side board, substantially as described.

2. In a dumping car, a truck, a car bed, and a side board therefor, in combination with rigid arms on said side board swinging supports for said arms, fulcrum bars pivoted at one end to respective swinging supports and at their other ends adapted to rest upon said truck and toggle members connecting said respective arms and fulcrum bars; whereby said side board is raised and turned into a plane substantially parallel with the floor of said car when the car body is tilted to discharge the load, substantially as described.

3. In a dumping car, a truck, a car bed, and a side board therefor, in combination with swinging supports for said side board, fulcrum bars each pivoted at one end its respective swinging support and adapted to rest upon said truck, toggle levers connecting said side board with said fulcrum bars, and adapted to turn said side board upon its pivot into a plane substantially parallel with the floor of the car when the car body is tilted to discharge the load, substantially as described.

4. In a dumping car, the combination of a car body, with a side board therefor, arms rigidly secured upon said side board, swinging supports for said side board pivoted at one end to the car body and at the other end to said rigid arms, fulcrum bars or props for said swinging supports and links connecting the arms on said side board with said props, said links and said arms forming toggle levers for turning said side board, substantially as and for the purpose described.
