DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 635,421, dated October 24, 1899.

Application filed May 4, 1899. Serial No. 715,564. (No model.)

To all whom it may concern:

Be it known that I, MORTON G. BUNNELL, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Dumping-Wagons, of which the following is a specification.

My invention relates to a construction of dumping-wagon in which'the bottom of the wagon-body is divided into sections arranged to open downwardly for the purpose of dumping the load.

Objects of my invention are to provide a construction involving simplicity, easy operation, facility for rapidly and effectively dumping the load, adaptability for uniform adjustment and for positive and certain closure at the bottom of the wagon-body regardless of inequalities in the operating and adjusting devices occasioned by strain and continued use, to improve upon the construction described in Letters Patent of the United States No. 532,785,dated January 22, 1895, and to overcome various disadvantages which in practice have been found incident to the arrangement described in said patent, and also to provide a construction involving a higher degree of practicability and efficiency than that disclosed by Letters Patent of the United States No. 17 7,324, in which the bottom of the wagon-body consists of a single board or piece suspended by chains hung outside the wagon-body.

To the attainment of the foregoing and other useful ends myinvention consists in matters hereinafter set forth.

In the accompanying drawings, Figure 1 represents in side elevation a dumping-wagon understood to embody the principles of my invention. Fig. 2 is a central longitudinal section on a vertical plane through the wagon shown in Fig. 1. Fig; 3 is a top plan View of said wagon. Fig.4 is a transverse section on line 00 0c in Fig. 1.

The wagonbody A, which serves as a receptacle of suitable area for receiving and carrying the load, can be supported from the front and rear wheels B C in any ordinary or desired way. While such wagon-body could be of the ordinary rectangular box shape, it is preferably formed with inclined front and rear ends a a, somewhat after the style of an oblong hopper. The bottom of the wagonbody is divided longitudinally into a couple of sections D, which are hung at points adjacent to their outer longitudinal edges by short cables or chains or like flexible connections E, attached to the bottom sections and to the sides of the Wagon-body. These chains while suspending the bottom sections at their outer edge portions serve as flexible hinge connections between the bottom sections and sides of the Wagon-body. Said chains E are arranged within the Wagon-body and are attached to the bottom sections at points a little back of the edges of such sections, 'so as to allow said edges to abut against the inner Walls of the sides a of the wagon-body when the bottom sections are in normal horizontal position, as best shown in Fig. 4. With this arrangement the outer longitudinal edges of the bottom sections will bear against the sides of the wagon-body when the bottom sections are permitted to swing downwardly, and when the bottom sections have swung downwardly to an extent to hang in vertical planes, as in Fig. 4:, their marginal portions, to which the chains E are attached, will lie against the inner walls of the sides of the wagon-body.

By employing chains or like flexible connections in place of pintle-hinges'the bottom sections will at all times be free to operate, it being obvious that were ordinary hinges employed the pivot or pintle bearings would sooner or later become so rusted and clogged with dirt as to seriously interfere with the free action of the hinges.

The chains E form strong and durable connections between the bottom sections and sides of the wagon-body. Said chains can also be applied and made of such length that the outer longitudinal edges of the bottom sections D will normally abutagainst the sides of the wagon-body a little above the lower edges of such sides, whereby should any sag occur by reason of long use the Wagon-body will still be closed at the bottom when the bottom sections are in their normal horizontal position. When the bottom sections are permitted to swing down, as in Fig. 4, the load will evidently be freely and fully discharged.

The bottom sections can be, and as a matter of further improvement are, operated by chains or cables F, but one chain or cable being necessary for each bottom section. As a preferred arrangement the chains E, which serve to hinge the bottom sections to the sides of the wagon-body, are attached to such bottom sections near the ends of the latter, while the raising and lowering chains F are attached to the bottom sections at points midway of the ends of such bottom sections. The chains F pass through openings a in the sides of the wagon-body, and at such points these chains are carried over or about small antifriction rolls or pulleys, which also serve to properly direct the chains or cables. For example, the chains which extend upwardly from points adjacent to the inner edges of the bottom sections first pass overantifriction guide rolls or pulleys Gr, arranged within or adjacent to the openings a in the sides of the wagon-body, and thence pass about guide rolls or pulleys H, also within or adjacent to said openings, the pulleys G being arranged upon horizontal axes, while the pulleys H are arranged upon vertical axes. The chains F are extended from the pulleys H forwardly to the front of the wagon and attached to a transversely-arranged rotary winding shaft or drum I,mou nted upon the forward end of the wagon-body and conveniently arranged below the drivers seat K. Any suitable means adapted for operating and locking the winding shaft or drum and arranged within convenient reach of the driver can be employed. For example, the shaft can be operated by a lever-handle L, hung loose upon the shaft and carrying a pawl M, arranged to engage a ratchet N, fixed upon the shaft. ith such arrangement the shaft can be locked by a pawl or dog 0, pivoted on the wagon-body and arranged within easy reach of the driver. This arrangement does away with the objectionable presence of a winding-shaft over the receptacle formed by the wagon-body and also does away with the objectionable feature of a couple of operating-chains to each bottom section. Hence should either chain F sag or lengthen the bottom section to which it is attached can still be drawn into proper position, it being obvious that where two operating-chains are attached to one bottom section undue extension of one of such chains will cause one end of such bottom section to be drawn up higher than the opposite end when the section is adjusted for the purpose of closing the wagonbody at its bottom.

\Vhat I claim as my invention is- 1. A dumping-wagon comprising a couple of swinging bottom boards hinge-connected with the side-boards at their outer edges; each board being operated and upheld by a single chain which is attached to the board at a point substantially midway between its ends, and which is extended upward over a couple of small sheaves or rolls in one of the side-boards and then forward to winding mechanism arranged within reach of the driver.

2. Adumping-wagon having a bottom comprising a couple of swinging sections suspended from opposite sides of the wagon-body by pendent chains or cables arranged within the wagon-body and constituting hinge connections between the outer longitudinal marginal portions of the bottom sections and the longitudinal sides of the wagon-body, said pendent chains or cables being of a length to hinge the bottom sections at points along their outer marginal edge portions and to maintain such edge portions in juxtaposition to the sides of the wagon-body; a chain or cable attached to each swinging bottom sec tion between the ends of the latter for the purpose of operating the same, and extending forwardly toward the front end of the wagon; and winding mechanism for said operatingchains arranged at the front end of the wagon, substantially as described.
