COAL-SCUTTLE.

SPECIFCATION forming part of Letters Patent No. 325,595, dated September l, i885.

E), 1885. (No model.)

To aZZ whom it may concern:

Be it known that I, J urns DUNCAN, of Coshocton, in the county of Coshocton and State of Ohio, have invented new and useful Improvements in Coal-Scuttles; and I do hercby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which 'form a part of this specification.

This invention relates to certain new and useful improvements in the construction and operation of coal-scuttles such as are employed for feeding surface-burning stoves through side feed-doors, although it will be found valuable in feeding what are ordinarily termed baseburners which are fed at the top.

In those sections of the country where soft or bituminous coal is employed for heating purposes it is usually burned in surfaceburning stoves, and in feeding the fuel through the side doors, and from the construction of the ordinary scuttles in use for that purpose, the coal is very apt to fall over the edges of the feeding platform or chute on to the iioor, and as this class of coal, when handled, forms considerable slack ortine particles and is shovelcd into the scuttles, there is a difficulty in discharging this slack into the side door of the stove without danger of soiling the floor.

The object of this invention is to provide a scuttle for the purpose that will prevent the coal from falling over the sides of the platform, and by means of which the slack can be fed without difiiculty.

The invention consists in the peculiar conn struction ot' the various parts and their coinbinations and operation, as more fully hereinafter described.

Figure l is a perspective view of my improved coal-scattle. Fig. 2 is a sectional view showing the mechanism, which is partially concealed in Fig. l.

In the drawings, A represents the body of the scuttle, and B the bailthereof, both made described. The platform or chute in the ordiallel sides extending from near the bottom ot' the scuttle to its top, in front of the place usually occupied by the discharge-chute. An endless conveyor, D, runs over the polygonally-shaped pulleys C, which are secured to the shafts d, one near the top of the scott-le and the other near the bottom of the chute, the ends of the shafts being suitably journaled in the walls of the seattle. One of these shafts is provided with a handle, by means of which the carrier is operated. An apron, E, is secured across the body just in rear of the conveyor, extending far enough upward to hide the lower end of such conveyor. Two wings, F, curved to conform to the shape of that portion of the body to which they are attached, are pivotally secured to said body just in front of the position of the ears which carry the bail. In rear of the pivotal points these wings terminate in bell-crank-shaped levers d', the free ends of which terminate in outwardly-projecting flanges so arranged that when the bail is forcibly depressed to the rear it will strike such anges and raise the wings, as shown in dotted lines in Fig. l. These wings extend forward when depressed, so that they are concealed by the conveyor, and terminate in upwardly-projecting guards e at a point immediately above the upper shaft.

In practice, when the seuttle has been iilled with coalin the usual way and it is desired to discharge its contents into the stove through the side door therein, the bucket is raised to the proper position, the ch utc presented to the open door, and the scuttle tilted in the usual way, when the bail depresscs the levers and raises the wings to prevent the coal from spilling over the sides ofthe chute, the guards resting against the stove on either side of the door. The coal will now be discharged into the stove, leaving the slack still in the bucket and resting upon the rear face of the apron, and by tilting the bucket a tritle more this slack will be discharged upon the conveyer, and the operator, by rotating such conveyor, will force such slack into the stove withoutfurther trouble.

The pulleys which carry the conveyer may be provided with sprocket-wheels, in which case the conveyor should be so constructed as to work with such wheels; or any other form of construction may bc adopted at pleasure so IOO long as a conveyer is had which will perform as required.

I am aware of the Patents Nos. 119,788, 141,485, and 160,873, and make no claim to the constructions shown therein as forming part of my invention.

I attach importance to my endless eonveyer, for by its use I am enabled to thoroughly empty the scuttle of the slack, there being no danger of any of it being carried back into the seuttle, as is apt to be the case at each return of a reciprocating slide.

I also deem it important that the wings be pivoted so as to Work on the inside of the seut- 11e, for Where they Work on the outside thereof, as has heretofore been proposed, the dust and fine dirt from the coal will sift through be tween the sides of the seuttle and the wings onto the door; but by my arrangement the dust, Ste., will fall back into the seuttle.

What I claim as my invention is- 1. A eoal-scuttle having an endless conveyer operating Within its discharge-chute by means of a crank, substantially as and forv the purpose described. Y

2. A coal-seuttle having Wings pivotally secured to the sides thereof independent of the bail and working on the inside of said seuttle, combined with a bail pivoted to said seattle and constructed to operate said Wings, as and for the purposes specified.

3. In combination with a coal-seuttle, Wings to prevent coal from discharging over the sides of the chute, and an endless eonveyer, as described, for forcing the slack coal to discharge.
