MICHAEL T. BRANSFIELD, OF CHICAGO, ILLINOIS.

DUMP CAR 0R WAGON.

To all whom t may concern:

Be it known that I, MICHAEL T. BRANS- FIELD, a citizen of the United States, residing at Chicago, in the count-y of Cook and State of Illinois, have invented certain new and useful Improvements in Dump Cars or Wagons, of which the following is a spec1- fication.

In the construction and use of a dump car or wagon, it is of considerable importance that all complicated mechanism, and parts likely to become clogged with dirt, be done away with, and it is therefore the primary object of my invention to provide a simply constructed dump car in which the operating parts are all of such a nature as no-t to be affected by clogging of dirt, stones or other material.

Another object of my invention is to provide a structure which will be invertible and provided with means whereby to displace its base to an extent necessary to free any material adhering thereto.

My invention is shown in specific embodiments in the accompanying drawings, in which- Figure 1 is a side elevation showing a complete apparatus including a dump car and hoist, both at the position of rest. Fig. 2 is a similar view showing the dumping body raised by the hoist. Fig. 3 is an end elevation illustrating the preliminary release of the dumping body. Fig. 4 is a similar view illustrating the parts in the act of dumping. Fig. 5 is a perspective view of one end of a dumping body forming part of a modified form of my invention. Fig. 6 is a similar view of a part of a hoist used in connection with the form of my in- Vention shown in Fig. 5, and Fig. 7 is a side elevation of the parts shown in Fig. 5 and also a portion of the hoist.

Referring now specifically to my invention with particular attention to Figs. 1 to 4 inclusive, I provide a dumping body 10 comprising a base 11 and sides and ends, the sides and ends being rigid while the base is movably connected by links 12 to the ends. This dumpingbody 10 may be the body of a wagon, so, as shown in the drawings, it may be supported upon a truck 13 wheeled for travel upon rails. In any event, the ends of the body are provided, at points substantially centrally between the sides, with vertical brackets 14, the upper ends of which have outstanding angular extensions 15 ad- Specication of Letters Patent.

jacent to the upper body edge, and the lower ends of which assist in supporting studs 16 which project outwardly from the body ends below points centrally between their upper and lower edges. The extensions 15 are apertured for a purpose to be hereinafter described. In connection with this body 10 I utilize a hoist comprising a horizontal beam 17 from the ends of which depend chains 18. These chains 18, as clearly shown, terminate in rings 19 adapted to engage the body studs 16, and have intermediate hooks 20 adapted to extend upwardly through the apertures in the extensions 15. It will thus be seen that the connections between rings 19 and hooks 20 are flexible, so that when said hooks and rings are properly engaged and the body 10 raised from its support as shown in Fig. 2, it may be carried over the point where its contents are to be dumped and lowered until it is supported on the dump, when the hooks 20 will automatically disengage from the extensions 15, as shown in Fig. 3, leaving the body free to swing to an inverted position, when again raised, on the studs 16, as shown in Fig. 4. As the body 10 inverts itself during the last described circle in the dumping operation, pins 21, outstanding from the ends of the body base 11, will come in contact with the chains 18 and canse the displacement of the base to the position shown in Fig. 4, and to an extent fully sufficient to dislodge any dirt or material adhering thereto.

In some cases, such as when dumping material into an excavation of some depth, it may be inconvenient to lower the body in order to effect a preliminary release, and in these cases such a construction as shown in Figs. 5, 6 and 7 may be highly important. The body 10, and in fact all of the parts of the dumping body, are exactly the same, however, as previously described, the onl difference being that instead of the hooks 20, the hoisting chain 22 in this form of the invention lis provided with a U -shaped keeper 23 in addition to its end ring 25, said keeper being pivotally connected to the chain by means of a pin 24 projected through the ends of its extensions and through a link of the chain. This keeper is adapted for engagement over an upstanding rib 26, with which the angular extension 15 of bracket 14 is provided in addition to its opening 27, in order to hold the body in an upright position until ready to dump, when a release cord 28 may be pulled to raise the keeper and thus leave the body free to invert as before described.

I claim:

l. A dumping apparatus comprising a dumping body having a base, a support for said body, brackets secured to the ends of the body, and having outstanding studs and angular extensions, in combination With means to engage said studs to raise the body, and havin connections for temporarily engaging said bracket extensions to prevent the body from inverting.

2. A dumping apparatus comprising a portable dumping body having a displaceable base, means for engaging portions of said body to raise and transport the same, means to maint-ain said body in an upright position, said last named means being releasable, and means coperating With said first named means to cause displacement of the base When the body is inverted.

3. A dumping apparatus comprising a portable and invertible dumping body, a base for said body having movement With respect thereto, and means to cause movement of the base With respect to the body When the latter is inverted.

4. A dumping apparatus comprising a portable dumping body having brackets secured to the ends thereof, and having out-- standing studs and angular extensions provided With apertures and projecting ribs, for the purpose described.

5. A dumping apparatus comprising a portable dumping body having a base, and links connectlng said base with said body whereby it may move With respect thereto, brackets secured to the body ends and having outstanding studs and angular extensions provided With apertures and projecting ribs, and outstanding pins carried by the ends of the base, all for the purpose described.

6. A dumping apparatus comprising a receptacle, suspension means for the receptacle, said suspension means including a ring and a hook Which are connected, studs on opposite sides of the receptacle, said studs being located below the center of gravity of the receptacle, and apertured members extending from the aforesaid sides of the receptacle and located above the aforesaid studs, the hooks on the suspension means being engageable with the apertures of said members, and the rings being engageable With the studs.

7. A dumping apparatus comprising a tiltable receptacle having a loose bottom, suspension means for the receptacle, and pins projecting from the bottom, into the path of Which pins the suspension means extend when the receptacle is tilted.

In testimony whereof I arix my signature in presence of two Witnesses.
