l I Application filed November 12, 1883. (No model.)

To @ZZ whom it may concern:

Be it known that I, G. GALvERT EGERTON, of the city of Baltimore, State of Maryland, have invented certain Improvements in Coal- Ca-rts, of which the'following is a speciiication.

This invention relates to certain improvements in that class of coal-carts in which the hopper is susceptible of elevation independently of the body, to admit of its contents being rapidly discharged through a chute directly to the coal-cellar, as will hereinafter fully appear.

In the accompanying drawings, forming a part hereof, Figure I is an exterior side elpe-` lshape to the bottom of the hopper O, on which the said hopper rests when loaded and during transportation.

E E are standards, to which levers F F are .pivoted 4The leversv FF are connected at one end to the hopper C by means of a rod, c, and at the other end are attached by chains to Winding-drums G on a shaft, d, supported in bearingboxes secured to the frame D. The shaft d is revolved from another, e, through the medium of gear-wheelsf g and crank h. The rod o is situated considerably forward of thecenter of gravity of the hopper, in order that in H, hinged at its'upper end to the bottom of the hopper. The lower end of the post passes l with a iianged sheave, fi, which rests on an inclined bar, la. The post is connected by a chain, Z, to a winding-drum, I, similar to those before alluded to, situated centrally of the shaft d, and as the hopper O is elevated the vpost H is drawn out and sustains its rear end.

If desired, a second post, located at the forward end of the hopper, may be used in connection with the rst; but this is not considered necessary, as the said end is fully supported by the levers F F.

The 'bar k may be toothed to form a rack, and the lower end of the post adapted as a pawl; but with this construction, in order to lower the hopper, the post would have to be rst disengaged from the rack.

I claim- 1. In a coal-cart, a Wheeled body, a hopper susceptible ,of elevation independently of the body, a' pair of levers having their fulcra on standards projecting from the body,`,pivoted at one end to the hopper, and at the other end attached by chains to win ding-drums, all com bined substantially as and for the purpose specified.

2. In a coal-cart, a wheeled body, a hopper susceptible of elevation independently of the body, a pair of levers having their fulcra on standards projecting from the body, and pivoted to the hopper at a point forward of the center of gravity thereof, and windingdrums and chains to operate the levers, combined with a post hinged at its upper end to the rear portion of the body, and at its lower end resting on an inclined box, and a chain to unite the said post with a winding-drum, whereby in the elevation of the hopper one end thereof is sustained independently of the elevating-levers, substantially as specified.
