AUTOMATIC SCREEN CHUTE, GATE, COAL=BlN, 84.0.
SPECIFICATION forming part of Letters Patent No. 325,343, dated September 1, 1885.
(No model.)
To aZZ 1072,0112, it may concern:
Be it known that I, BENJAMIN Knrnnn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new anduseful improvements in automatic screen chutes and gates, and double-in cline-plane-bottomed coal bins or pockets, and dust-box and screen attachments; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawlugs, and to the letters and figures of reference marked thercon,which form a part of this specification.
This invention relates to improvements in coal-chutes; and it consists in the combination and a wrzni'geineht oi the several parts hereinafter dcscribechand pointed out in the claims.
In the drawings, Figure 1 is a plan YIGW of a coal-bin constructed according to my invention. Fig. 2 is an end elevation of the same. Fi 3 is a longitudinal section of the same. Fig. at is a detail view.
In the accompanying drawings, A: is the bin, pocket, or receptacle, of rectangular or any other desired shape, with inclined planes B B, forming the bottom and pitching from the center or apex C downward. I have shown in the drawings only two inclines B 5 but it will be understood that the bottom of the bin or pocket could be made in the shape of a pyramid having'four inclines, in which case I could use four chutes and screens of pattern hereinafter described.
At the lower end of each inclined plane a discharge-opening, D, is formed through the side of the receptacle, and through this opening the coal runs onto the chute.
A gate, E, is arranged to close the dischargeopenin The gate is held down by weights or springs. I prefer to employ a spring, E, as shown, though any counterbalancing force known in mechanics could be employed. The spring is only one of these forces,and I do not limit myself to its use. To the framing I hinge the screen-chute I*, which is arranged to receive the coal as the latter emerges from the receptacle. The chute is provided with a screen-bottom, F, and it is connected with the gate E by a cord or chain, E, which passes over a pulley, E, journaled in the framing inst above the discharge-opening. Instead of a single cord and chain and a single pulley, two cords or chains and two pulleys could be used. I prefer one of each, and arranged as shown. The spring Eis of such strength that it will hold the gate down and the chute in a horizontal position. By pulling the outer end of the chute down the gate is raised so that the coal can flow through the discharge-opening.
.Iust below the screen-chute I arrange a return-chute, G, which has the upper side of its outer end made on an incline to permit the pulling down of the said screen-chute. The inner end is provided with a screen, G arranged over the dust-box C. The dust-box may have drawers in it, or it may be a plain box, from which the dust may be shoveled.
A track, H,i'or the coal-cars can be arranged on the top of the receptacle, as shown.
I prefer to have the screen chute and gate connected together and simultaneously operated, as hereinbefore described, but a rope or lever could be secured and used to raise the gate, and a separate weight could be attached to the cords which draw up the screen-chute. The screen-chute when raised to the horizontal position would prevent the coal from running out in case the gate was accidentally raised. A small portion of the coal would run out onto the inner edge of the screenchute, but not sufficient to depress the latter.
Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-
1. The combination of a coal-hopper having an inclined bottom and a dischargeopeninga vertically-sliding gate to close the dischargeopening, a hinged spring-chute arranged on the outer side of the coalaeceptacle at the lower side of the discharge-opening, a flat spring hearing on the upper edge of the gate, and a cord attached to the chute passing over a pul ley and connected to the gate, as and for the purposes set forth.
2. The combination,with the coal-hopper A, having dischargeopening D, of the screen F,
hinged to said receptacle below the discharge turn-chute G, and screen-extension G, forinopening, and the return-chute G, extending being the dust-receptacles G, the parts eonyond the hopper, its inner end, G projected strueted,arranged,and operating substantially beneath the hopper and forming the dust-box as shown and described. :5 5 G, substantially as shown and described. In testimony whereof I affix my signature in 3. The combination of the hopper A, havpresence of two witnesses. ing double-inclined bottom B B,and discharge openings D,track H, located immediately over BENJAMIN KEPNER" the apex of the bottom, Vertically-sliding doors :0 E, flat spring E, hinged spring-chutes F,eord
