SPECIFICATION forming part of Letters Patent No. 447,774, dated March 10, 1891.

To aZZ whom it may concern:

Be it known that I, JOSEPH ALLEN HEAD, a citizen of the United States, residing at Greenfield, in the county of Highland and State of Ohio, have invented certain new and useful Improvements in Dumping-Wagons; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form part of this specification.

This invention relates to those dumpingwagons which are provided with a number of tilting bottom boards or sections that can be readily inclined at any suitable angle to discharge a load from the vehicle, and my improvement comprises a novel combination of interlocked levers that prevent accidental shifting of said sections, as hereinafter more fully described.

In the annexed drawings, Figure 1 is a side elevation of my improved dumping-wagon, one of the rear wheels and a portion of the frame being broken away to render the construction clear. Fig. 2 is a longitudinal section of the body of the wagon, the tilting bottom boards thereof being in their horizontal or normal positions and the stop devices so shifted as to unlock or liberate said boards. Fig. 3 is a similar section, but showing the tilting boards inclined to dump the load. Fig. 4 is an enlarged vertical section of the levers and their accessories.

The main frame A is supported upon ordinary runningears and carries any conven- 3 5 ient form of bed or body, a stop-beam B being disposed transversely of said frame and near the mid-length thereof, which beam has suitable journals or bearings 12. C and D are transverse rocking beams located between this beam B and the opposite ends of the frame, said beams O D being provided, respectively, with journals or bearings ed.

E is a transverse rock-shaft at the rear end of frame A and having an arm 6 and one or more projectinglugs or stops e, which latter are normally horizontal and support the rear end of a tilting bottom board or section F, rigidly attached to the rocking beam 0.

G is another tilting bottom board or section secured to the rocking beam D.

The journal I) of stop-beam B serves as the common fulcrum for a pair of levers II I, the outer one of which II is rigidly attached to said fulcrum, while the inner lever I is free to swing thereon, as seen in Fig. 4:. v

72, is a rod that connects the lever II with the arm 6 of rock-shaft E.

t' and z" are rods that connect the leverI with arms 0 and d, attached rigidly to the journals e (Z of rocking beams O D. These levers must be temporarily locked together by some convenient device,a-simple hook J being seen in Fig. 1, while in Fig. 4 a spring-bolt K is shown applied to the outer lever H, which bolt engages with a keeper L, attached to the other lever I.

Then the various operative parts are in their normal positions, (seen in Fig. 1,) the levers II I are swung forward, which act so rocks the shaft E as to cause its lug e to be about horizontal,and thereby support the rear or heavier end of tilting section F. Furthermore, in this normal position the stop beam B is horizontal, as indicated by the dotted lines in Fig. 2, and thus supports the heavier end of section G, and the levers H I are now temporarily coupled together by the fasteners J or K or their equivalents. The wagon is then filled and drawn to the place where the load is to be dumped, accidental tilting of the various pivoted bottom boards or sections being prevented on account of the two levers being united. Consequently there is no danger of the rock-shaft E being operated, because its lever H is now coupled to the other lever I, and the latter is connected by the rods 11 t" to the rock-beams O D,which beams support the greater part of the load. To dump the contents of the Wagon the hook J, or spring-bolt K is disengaged, so as to uncouple the levers I1 I, and the former is then swung back to the position indicated by the dotted lines H in Figs. 2 and 3, the result being to rock the beam B and shaft E in such a manner as to leave the rear ends of sections 95 F G unsupported. Lever I is then swung back to the'position indicated bythe dotted lines I in Fig. 3, thereby tilting said sections at such an angle as to discharge the load directly upon. the ground. This lever is now 100 pulled forward to its original position, thus bringing the sections to a horizontal, and then the lever H is pulled in the same direction, which last act brings the stops B and e in under the rear ends of said sections. These levers are then again coupled together and the wagon loaded and dumped, as previously explained. From the above description it is apparent that by simply mounting the stop and dump levers upon a common bearing or pivot and coupling them together there is no danger of the stop mechanism being accidentallyliberated either by the jolting of the wagon or otherwise.

I claim as my invention- The combination, in a dumping-wagon, of the main frame A, a stop-beam B b, rock-shaft E e e, a pair of rock-beams C o c D (l (1,
