DUMP'ING WAGON.
110.314.2368. Patented Mar. 31, 1885.
UNITED STATES ,PATENT OFFICE.
JAMES J. MURPHY, OF PHILADELPHIA, PENNSYLVANIA.
DUMPlNG-WAGON.
SPECIFICATION forming part of Letters Patent No. 314,868, dated March 31, 1885.
Application filed May 28, 1884. (No model.)
To all whom it may concern:
Be it known that I, JAMES J. MURPHY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Dumping- Wagons; and I do hereby declarethe following to be a full, clear, and exact description of the invention,reference being had to the accompanying drawings, which form part of this specification, in which- Figure 1 is a vertical section of a wagon with my improvements applied. Fig. 2 is a plan.
My invention has relation to that class of wagons in which the body is elevated by mechanism when it is desired to discharge the contents by means of a chute.
The object of my improvements is to provide an improved combination of devices by means of which the body can be elevated to any required extent, and at the same time duly projected at or toward the rear.
My invention consists in the peculiar construction and combinations of parts hereinafter fully specified, having reference, particularly, to the levers by means of which the elevation is effected and to two sets of chains, the functions and operations of which are hereinafter fully explained and set forth.
Referring to the accompanying drawings, A represents the sill of the body of a coal-wagon, and B the spring-frame, or frame by means of which connection is made with the springs, and through the latter with the axles C and D of the wagon, 0 being the front and D the rear axle. The frames A and B are connected to one another at the rear by two levers, E E,
pivoted to brackets e e, the pivotal connection-points being shown at c e'.
F F are other levers, of the shape shown, having a bend or inclination toward the front at their upper ends. The levers F F are pivoted at ff to the body-sill A at points about midway between the front and rear ends of said sill, and their lower ends are connected to chains G G, which are attached to and designed to be wound upon a Windlass-shaft, H, which has its bearings in the spring-frame B. Said shaft has a pinion, h, with crank, which gears with a wheel, I, to be turned by the operator when it is desired to raise or to lower the body of the wagon. Short chains Zcjc connect the levers F F with the body-sill at points in the rear of the pivotal connections f f.
L is a shaft having its bearings in or on the spring-frame B, and having a winch or handle, Z, by which it can be turned. Chains Z Z, connected to said shaft and adapted to be wound thereon, are secured to the body-sill A at its forward end.
The operation is substantially as follows: Assuming that the body-sill is resting upon the spring-frame, (the normal position of the parts, except in unloading) and that it is desired to elevate said bodyin order to discharge its contents through a chute, the shaft L is first given a few turns to partially unwind the chains Z Z. The shaft H is then turned to wind up the chains G G. This causes the levers F F to ascend, and raises the body until the chains Z Z become taut, when, the winding up of chains G G being still continued, the rear end of the body rises, the levers E E travelin g in a circle whose center is their lower pivotal points. At the same time that said body rises it moves backwardly, so that its rear end will project over the rear of the spring-frame. Should further elevation and projection of the body be required, more slack is given to the chains Z Z and the winding up of chains G G further continued. The short chains 1c 70 serve to check the movement of the leversF F, and so prevent the body-frame from falling backward. on the spring-frame. As an auxiliary to or substitutes for these chains k k, I may ernploy stops m, which serve to limit the forward movement of the lower ends of the short arms of the levers E E, said stops being affixed to or formed on the brackets e e or on the springframe. To lower the body, the shaft H is turned in a direction opposite to that required to raise said body, the chains G G then unwinding, and the levers F F dropping until they rest with their front edges against or 9 body above the spring-frame than can be secured by any previous construction with which I am acquainted. I also secure all the required rearward extension or projection of the body.
Owing to the peculiar shape of the levers F F, I am able to secure ahigher lift than could be had with straight levers, and said levers likewise obtain, when lowered, a bearing or rest upon the shaft H, which prevents them from falling forward in the way of the front wheels of the wagon.
In lieu of the check-chains k is, levers or con neeting-rods having a joint or hinge at or about their middles may be employed.
WVhat I claim as my invention is as follows:
1. The combination, with the wagonbody A, supported on frame 13, the levers F F, attached to the body A at their upper ends, and provided with cheek-chains 7c is, of the shaft H and chains G, attached to said shaft and to the levers F F, substantially as shown and de scribed.
v2. The combination, with the wagonbody A, supported on frame B, and the levers F F, attached to the body A at their upper ends, the shaft H, and chains G G, attached to said shaft and to the levers F F, of auxiliary levers E E, pivoted to'the frame and body, and stops in m, for limiting the movement of said levers, substantially as described.
3. In an elevating-bodyor dumping wagon, the combination, with the body and a winding-shaft, H, of leversF F, having their lower ends attached to said chains and their upper ends pivoted to said body, said levers being bent in a forward direction at their upper ends, substantially as shown and described.
In testimony that I claim the foregoing I have hereunto set my hand this 2lth day of 40 May, 1884.
