COAL-CHUTE.

QFDEJCEFICATION forming part of Letters Patent No. 312,207,dated February 10,1885.

Application filed December I8, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, MOSES D. JONES, of Jackson, in the county of Jackson and State of Ohio, have invented a new and Improved Coal-Chute, of which the following is a full, clear, and exact description.

My invention relates to apparatus used in mines for discharging coal from the screens into cars. It has been usual heretofore todischarge the coal directly from the mine-cars upon the screens, and thence into the railroadcars, so that it does not rest after itis dumped until it lands in the railroadcars, and by the time it reaches there it has gained such an impetus that it is considerably broken up, especiallyin the case of lump-coal. Other methods have been used, but are objectionable for the same reason.

The object of my invention is to overcome this difficulty,which I do by the use of a swinging chute, which is filled with coal while in a nearly level position, and is arranged for then being lowered for the discharge of its load into the car, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings,forming a partor" this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a sectional side elevation of my improved coal-chute. Fig. 2 is a front view.

A frame-work, A, upon which the chute B is hung, is of suitable elevation, and located between the screens and the cars or track.

The chuteB is constructed of a comparatively wide and shallow form, and with its lower end slightly deeper than its upper end. It is hung at its upper end to hangers a a by a cross rod or shaft, 12, and at its outer end is suspended by means of ropes c,that pass from the outer end of the chute over grooved sheaves or wheels d, and are connected to a weight, 6, that is heavy enough to raise the chute when empty. The sheaves or wheels (I are upon a cross-shaft, f, which also carries a brake-wheel, g, and the brakewheel is fitted with a friction-band, h, the loosecnd of which is-connected to a weighted lever, i, by which the band is pressed upon the wheel with sufficient force to sustain the chute when loaded. A rope, k, connects to the lever z and passes to a convenient point for being drawn upon by the operator to raise the lever and release the friction-band. At the lower end of the chute is a hinged gate, Z, that is kept closed by a cross-bar, in, that is attached to the ends of arms a, pivoted at the sides of the chute, and from the bar at a cord or cords, 0, pass upward and are attached to a fixed point, so that as the chute moves downward the bar 122. will be raised, and the gate thus released as soon as the ropes 0 are tightened by the movement of the chute. Chains or ropes q are connected and pass downward to the weight 6, to which they are also connected. These chains are of such length that when the chute reaches its highest point they become taut, and thus transfer the weight from the ropes 0 directly to the chute, so as to prevent it from rising too far. The chains are also provided with turn-buckles for the adjustment of their length.

In the operation of the apparatus,the incli- I nation of the chute in its raised position being properly adjusted, the coal coming over the screens will run upon the chute with just momentum enough to reach the end-gate and then spread over the bottom of the chute. When the chute is filled ,the brake is released by operation of the lever t, and the weight of the coal then carries the front end of the chute down,so as to discharge directly into the car. WVhen the coal is all out, the brake is again slackened and the chute is raised to its first position by the weight. By these means the coal is discharged easily and slowly into the car without the breaking up incident to the ordinary way of handling the coal.

4 In connection with the chute any suitable arrangement may be made for weighing the coalas, for instance, the hangers of the chute may be secured to the scale-timbers and the coal weighed while in the chute.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The apparatus for discharging coal, consisting ofa chute, B, hinged at one end, and sustained at its outer end by a weight, and brake mechanism for releasing the weight, allowing the descent of the chute when filled, substantially as described.

2. In coal-chutes, the combination of the hinged chute B, ropes 0, weight 6, the grooved wheels d, and the brakewheel g, substantially as shown and described.
