COAL-CHUTE.

SPECIFICATION formingpart of Letters Patent No. 270,736, dated January 16, 1883.

Application filed November 21, 1882.

To all whom it may concern:

Be it known that we, ISAAC BURNETT and JOSEPH E. CLIFTON, of Geneseo, in the county of Henry and State of Illinois, haveinvented new and useful Improvementsin Coal-Chutes, of which the following is a full, clear, and exact description.

Our improvements relate to the construction and arrangement of coal-chutes used for coalin glocomotive-tenders and other carriages, the

"object being to dispense with complicated mechanism and to save timein the coaling operation.

Our invention consists in the combination, with the coal box or chute, of a balanced apron, which, when turned down, forms a chute or slide from the delivery end of the main box or chute.

It consists, further, in the construction whereby the operation is rendered more effective and the gate of the coal-box is automatically released when the apron is brought in place for discharge of the coal, as hereinafter described and claimed.

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

Figure 1 is a side elevation, partly sectional,

of our improved coal-chute. Fig. 2 is a front view of the same. i

A is the box or chute, which is elevated upon a suitable frame at the side of the elevated track a, as usual, on which the coal-cars are conveyed for filling the chutes or boxes placed alongside ofthe track. The chute A is formed with an inclined bottom,b, that is constructed of planking covered on the upper side by iron plates. The object of thus constructing the bottom is to obtain durability, and also to facilitate the disch arge of the coal in cold weather, when the coal is apt to adhere to woodenbottomed chutes. At the front of the chute A is a swinging gate, c, hinged at its upper edge, so as to close the front or open side of the box, and this gate is held in its closed position by means of latches d, which are pivoted at each side of the supporting-frame ot' the chute. B is'the apron, formed of sheet-iron, and with side rims or flanges. supporting-frame of the chute by hinged joints,

This apron is attached to the- (No model.)

of the apron. At their outer ends the armsf are bent at right angles, so as to form ofi'sets, to which weights 9 g are pivoted. The weights 9 have an arm or projecting portion, g,of suitable length and form for taking against the under sides of the armsf when the latter are raised by thedownward movement of the apron B, so that the weights shall beheld in a position projected from the ends of the arms], as shown in Fig. 1. The'armsfare bent and the weights so placed that they hang directly, or nearly so, beneath the center 0, on which the apron swings when the apron is in its raised position, the object being to insure the raising of the apron by the weight closely against the gate 0 and the face of the chute A. A suitable handle or rope, as shown at K, is fitted to the outer end of the apron, for use in drawing it downward.

In operation, the gate 0, beingclosed,is held by the latches d, the inner ends of which are of a weight sufiicient to throw thelatches into engagement with the lugs d on the gate, these inner ends being also provided with lugs or projections 13, projecting outward. The chute, being also in the raised position, as shown by dotted lines in Fig. l, is held by the weights g. The apron being drawn down, the arms f are thereby raised, and, coming in contact with the projections i ofthe latches (1 when the chute is fully down, the latches are thereby moved out of engagement with the lugs on the gate 0, and the gate, being thereby released, willbe forced open by the coal, and the coal willpass down over the apron to the tender or carriage. In this downward movement of the apron, as soon as the arms f approach a horizontal position, or nearly so, the projections g of the weights take against the under sides of the arms, and the weights are thereby prevented from swinging downward, and are held rigidly,

projecting from the ends of the arms, so that the weights act to the fullest extent during the completion of the movements. That construction allows. the use of lighter weights, the readystartingofthe apron, and also its quick start upward when first raised. 'When the coal is discharged and the chute raised again the latches dare released, and the gate a, falling by its own weight, is again caught by thelatches and held.

We do not limit ourselves to any particular form or arrangement of the chute or coal-box.

The apron B may be provided at its outer end with a latch or bolt arranged for engagin g a fixed catch when the apron is raised for holding the apron. The handle is will be connected to the bolt, so that at the first pull of the handle the bolt will be disconnected. This arrangement is to prevent the apron from being thrown down by the weight of coal in case the latches d should fail to catch or become disconnected by the jarof passing trains.

Having thus described our invention, what we claim as new, and 'desire to secure by Letters Patent, is-- 1. The combination, with a coal-chute, of a hinged apron provided with balancing arms and weights, and arranged to form,when moved downward, an inclined plane on the end of the chute or box, substantially as shown and described.

2. The combination, with a coal-chute, ofthe hinged apron B, provided with the weighted armsf, substantially as and for the purpose set forth.

3. The combination, with a coal box or chute, of the hinged apron B, the weighted arms 1', the hinged gate 0, and the latches d, substantially as shown and described.

4:. The combination, with the chute A, of the hinged gate 0, the latches d, provided with projections i, and hinged apron B, provided with arms f, constructed and arranged substantially as described, for effecting the automatic release of the latches when the apron is lowered, as specified.

5. In coal-chutes, the combination,with the hinged apron B and arms j, of the pivoted weights 9, having projections or arms g, substantially as shown and described.
