JOSEPH P. DELANEY, OF GREEN BAY, WISCONSIN.

DUMPING-BOX.

To all whom it may concern:

Be it known that I, J OSEPII P. DELANEY, a citizen of the United States, residing at Green Bay, county of Brown, and State of Wisconsin, have invented new and useful Improvements in Dumping-Boxes, of which the following is a specification.

My invention relates to improvements in dumping boxes with especial reference to that class of boxes used by graders upon wagons or other portable vehicles.

-The object of my invention is to provide means whereby the contents of the box may be discharged between the walls and at the sides of the reach bar through suitable door ways provided for that purpose, the door, when released from closed position, being arranged to swing downwardly and inwardly under the weight of the contents, and the walls of the box being arranged to direct the material toward the openings thus formed, whereby the entire contents of the box will discharge by gravity as soon as such doors are open.

In the following descri tion reference is had to the accompanying c rawings, in which,

Figure 1 is a side View of a box embodying my invention showing the doors in closed position. Fig- 2 is a plan view of the same. Fig. 3 is a view of the box as seen from the underside, and Fig. 1 is a rear end elevation.

Like parts are identified by the same reference characters throughout the several views.

The box is preferabl formed with vertical side walls 1 having a aring upper portion 2, and inner end walls 3 and 4 extending down wardly and inwardly from the upper margin of the box to points in the bottom wall within the lines of the bolster receiving cleats 5. The bottom of the box, at least between the end walls 3 and 4, inclines laterally and downwardly from the longitudinal center line 6, and the outer portion of each sloping bottom wall is provided with an opening adapted to be closed by means of a door 7 these doors being hinged to the bottom along their inner margins, preferably by means of the rod 10 and rod receiving leaves or butts 11.

Each of thedoors are reinforced on the underside by metallic frame bars 12, and the outer margin of the door is provided with a supporting member 13 comprising a bar offset in its central portion to project beyond Specification of Letters Patent.

the bottom of the box, and arranged with its ends riveted to one of the frame bars 12. This member 13 is connected with one arm of the door supporting lever 14 by means of a rod 15 and link 16, the link being employed to connect the upper end of the rod with the lever and the lower end of the rod 15being connected with the member 13 by a yoke 17.

The other arm of the lever is adapted to be engaged by a fastening clip 18 when the door is in a closed position, the fastening clip being adapted to normally hold the lever in such position until it is manually released by moving this end of the lever outwardly from under the laterally projecting shoulder 19 of the clip. The lever is connected with the vertical side wall 1 of the box by means of a fulcrum pin 20, and the load arm of the lever is preferably arranged to project upwardly and rearwardly from the fulcrum pin to the point of connection of the link 16. When-the lever is released from the fastening clip, the door is permitted to drop by gravity, the upper end of the rod 15 swinging outwardly and the lower end inwardly as the door swings on its hinges. The link 16 will of course limit the swinging movement of the rod 15 and will thus also limit the movement of the door, which, when in open position, is still preferably inclined laterally to some extent and adapted to guide the discharged material toward the side of the wagon. WVhen it is desired to again close the door, the rod 15 serves as a lever during the initial movement of the lever 14, thus drawing first outwardly and then upwardly on the door. The space underneath the rear inner wall 4 and between such floor and the bottom of the box is preferably utilized as a receptacle for tools by providing the outer rear wall 22 with a door fixed and swinging sections, hinges connecting the inner margins of the swinging sections with the fixed sections, operating levers pivotally secured to the respective sides of the box, rods, unconnected at any fixed point and having their lower ends loosely connected with the outer margins of the swinging sections, and links connecting the upper ends of such rods with the operating 1evers,said rods being arranged for fulcrurn bearing contact with the lower margins of the side walls during the initial closing movement of the swinging sections.

In testimony whereof I afiiX my signature in the presence of two witnesses.
