Application tiled June 4,1897. Serial No. 639,425. (No model.)

T @ZZ whom ift may concern:

Beit known that I, WILLrAM LnoNnARD'r, of the city of Baltimore and State of Maryland, have invented certain Improvements in Dumping-lVagons, of which the following is a specification.

In the description of the said invention which'follows reference is made to the accompanying drawings, forming a part hereof, and in Which- Figure l is an exterior side'view of the improved dumping-wagon. Figs. 2, 3, 4, 5, and are enlarged details of the invention. Fig.

' 7 illustrates a modilication in a part of the invention. v

Referring now to the drawings, A is the body of the wagon, and B and C are respectively the front and rear wheels.v

D D are sills supported by any suitable mechanism from the front axle E. These sills are of such length as to support the body in a horizontal position.

F F are plates bolted to the inner sides of the sills D, with their overhanging portions inclined downward. Their lower ends are enlarged, as shown particularly in Fig. 5, and through the enlarged ends is passed the rear axle G, which at this place is turned to a cylindrical shape. The holes a in the plates F are elongated vertically to give the axle a limited vertical movement indcpendentl y ofV the body and the sills.

The rear end of the body A is supported by springs H, secured to the axle G, and is not intended to bear on the sills. The springs l'l are therefore made strong enough to sustain the body when loaded in the position shown in dotted lines in Fig. 2, the lowering of the body to contact with the sills occurring only when the wagon is jolted by passing over rough places.

I is a bracket bolted tothe rear axle G at the longitudinal center thereof, and to it is pivoted the dumping triangular lever J. The upper arm b of this dumping-lever is curved, and its end is loosely attached to the under side of the body A by means of the strap c. The lower arm d of the dumping-lever, which is in an` angular position with reference to a vertical line when the body of the wagon is seated on the sills, as shown in Figs.

l and 2, is'strengthene `gthe braces c.

K is a revoluble shaft underneath the sills D, supported therefrom by hangers f. At one end of this shaft is a spur gear-wheel L, in mesh with a pinion M near the end of a shaft N, which is sustained in hangers g. The end of this shaft is made square to allow of the application thereto of a crank (not shown) which is used in the raising and lowering of the body, as hereinafter described.

O is a chain the upper end of which is attached to the curved portion b of the dumping-bar J bymeans of a shackle P, and its lower end is wound around and fastened to the shaft K.

Q Q are other chains with their upper ends wound around the shaft K in a reverse direction to the chain O, and their lower ends are fastened to the end of the straight part d of the dumping-lever J by means of a bolt 7L. (See Fig. 3.)

)Vith the arrangement of chains described it will be seen that when the chains Q are l wound the chain` O is unwound, and vice versa. Consequently no slackening of any chain can occur in tilting the body, and the body is heldrmly in any position in which it may be placed.

To tilt the body A, the shaft N is turned by the crank in the direction indicated by the curved arrow in Fig. l, which has the effect of winding the chains Q and unwinding the chain O. B y continued winding the bar J and the body A attached .thereto are brought into the positions shown in Fig. 4. The body is shown in the same position in dotted lines in Fig. l. brings the body back to its original position, so that its front end will seat on the sills D.

A hinged latch S (shown only in Fig. 6) is hooked over the square portion of the shaft N to hold the body in any position.

In tilting the body as described it will be understood that the rear axle G turns with the body. (See Fig. 4.) This turning of the axle in the dumping operation may be avoided by bolting the springs Il to a block T, (shown only in Fig. 7,) which turns about the axle, which is made cylindrical for the purpose.

In a dumpingwagon, the body thereof sup ported at one end by stationary sills, and at A reverse movement of the crank IOO the othe1l by sp1-ings sustained by the rear Wound, and the position of the level` and'its axle, combined With dumping-lever hinged attached body of the Wagon chzmgedubstan- Io to the rear axle oi"to an attachment thereof, tially as specified.
