HARVEY C. DANIELS, OF GRAND RAPIDS, MICHIGAN.

DUMP-WAGON.

Specification of Letters Patent.

Patented June 10%, 1913.

Application filed October 18, 19.09. Serial No. 523,364.

To all whom 2'25 may concern Be it known that I, HARVEY C. Daxnns'a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Dump- IVagons, of which the followin is a specification.

My invention relates to in'iprovements in wagon boxes for drawing sand, gravel, &c., and its objects are, first, to provide a dump ing attachment with which a load may be dumped the entire length of the box; second, to provide a bottom dumping wagon box with which every particle of the load of sand may be dumped, though a large portion of the weight of the load is carried by the sides of the box independent of the doors by means of which the load is released, and, third, to provide a wagon box; of the kind described, with which no sand; or gravel can sift or flow through any; crevices in the bottom of the box, and with which the axletrees will not interfere with the opening of the doors at the bottom of the box. I attain these objects by the mechal nism illustrated in the accompanying drawj ing, in which Figure 1v is an elevation of the hind end of a wagon box showing the construction. of the doors through which the load is to be 1 dumped, and the means whereby the box is: supported above the axletrees to avert the danger of the doors striking the axletrees when being swung open to dump a load of sand, &c. Fig. 2 is a transverse section of the box on the line 1 11 of Fig. 3, looking to the left. Fig. 3 is a longitudinal sectional elevation of the box on the line a: a; of Fig. 1, and Fig. 4 is an elevation of the front end of the box showing the mechanism for op erating the actuating shaft, and for holding the actuating lever in position to support the doors and their load.

Similar letters refer to similar parts throughout the several views.

The box A is made of sheet metal, and the lower edges of the sides thereof are made to incline inward, as at a, a, and an inverted V shaped ledge o having corresponding inclines, is located through the center of the box, longitudinally, for the purpose of making the opening between them as narrow as possible, so as to relieve the doors C C from as much of the weight of the load in the box as possible, without interfering with the free discharge of the load when the doors are opened. These inclines should not extend too far up into the box, but should be steep enough not to retain any of the sand when the doors are opened.

I place a wide door C, and a narrow door C, in each opening, said doors being pivot-- ally support-ed upon, or hinged to the lower edges of the inclines so that the edges of the doors project well back under the edges of the inclines for the purpose, first, of averting the danger of sand sifting through between the edges and wasting, and, second, to avert the danger of sand getting into the hinges and grinding them out.

The doors C C are supported in horizon tal position, as shown in Figs. 1 and 4, by means of cables or chains H H at the ends of the box. These cables are made to engage only the wide doors but at the center of the box there are branch cables, as H, that are connected at one end with the center cables H, and at the other end with the longitudinal center of the narrow doors C. The op posite ends of the cables H are secured to the shaft B, which shaft is supported in boxes one at each end A and one in the center, at A, of the box. This shaft is actuated by a lever F and has a ratchetwheel E secured to it in posit-ion to be engaged by the pawl I so that when the lever I is carried over toward the right, looking from the back of the box, the shaft 13 will be made to revolve and, with the doors C C and C 0 open, as in Figs. 2 and 3,'the cables will be wound around it and the doors will be drawn up to close up the bottom of the box, as in Figs. 1 and 4, and when the pawl I is disengaged from the ratchet wheel E the weight of the load on the doors will force them open so that the contents of the box A will be discharged through the open space between the inclines o and a.

I provide for securing the shaft from revolving and discharging the contents of the box when not desired, by the use of a pawl and ratchet wheel, or any other available means for the purpose, as indicated'at G or G in Fig. 4.

A slight offset, as c, is made in the doors G C so that when the doors are brought up to the position indicated in Figs. 1 and 4, the upper surfaces of each pair of doors will be upon the same plane, and the lower edges of the wide doors C C will project under the edges of the narrow doors 0 O" and thus form a dust tight joint between each pair of doors. To insure the perfect support of the narrow doors C C at the ends where they are not supported by the cables H, I place short arms, or ribs, as c a, so that they will project out from the lower edges of the wide doors and will pass under the'edges of the narrow doors before the several doors are closed, thus assisting the cables H to draw the narrow doors to place and properly sup port them and their load.

It will be readily understood that to op erate the doors the whole length of the box it will be necessary to elevate the box some distance above the axletrees J, and for this purpose I place high bolsters D D crosswise near each end of the axletrees, upon which the sides of the box are supported, and corresponding bolsters, as D across the centers of the axletrees to support the center inclines a. These bolsters should be high enough so that the doors may be opened without the edges coming in contact with the axletrees.

If it is desired to place the box nearer to the axletrees it will be necessary to form openings in the lower edges of the wide doors C C, as indicated in Fig. 2, so that they may extend down below the upper surface of the axletrees, and to avert the clanger of sand, gravel, &c., sitting or flowing through these openings I hinge small plates K to the upper surfaces of the doors, as at is, in position to cover the openings and lap over onto the doors C and form a sand tight joint over the axletrees.

To insure the closing of the narrow doors C before the wide doors C are closed, so that the edges of the doors C will certainly lap under the edges of the doors C, I place an evener H between the cables H and H, so arranged that the points of connection form a triangle with the lower points of connection upon practically the same plane and the upper point of connection above and midway between the lower ones, so that with the cables H drawing upon these eveners the wider, hence heavier of the doors in each pair will draw the end of the eveners down and cause the narrower, hence lighter of the doors to close first, and when it is closed the other doors will be drawn up under them and form dust proof joints between both pairs of doors, so long as the doors are closed.

hat I claim as new, and desire to secure by Letters Patent of the United States, is:

In combination with the axletrees, running gear and box of a dump wagon, high bolsters secured crosswise of the axletrees at each end and the center, the sides of the wagon box mounted on the bolsters at the ends 01": the axletrees with the lower edges of said sides inclined inwardly and projecting beyond the sides of the bolsters, an inverted V shaped ledge mounted on the bolsters at the center of the axletrees and extending longitudinal of the box forming inclines the lower edges of which project beyond the sides of the bolsters, a wide door hinged well back under the projecting lower edge of each side of the box and a narrow door hinged well back under the projecting lower edge of each incline in the center of the axletrees said doors extending the en tire length ot the wagon box, and means for opening and closing the doors.

Signed at Grand Rapids, Michigan, September 2 1, 1909.
