CHARLES (1. ROSE, OF SCRANTON, PENNSYLVANIA.
COAL-STOCK TRES-rre.
SPECIFICATION forming part of Letters Patent No. 414,725, dated November 12, 1889.
Application led March 20, 1889. Serial No. 304,046. (No model.)
.To all whom, t may concern,.-
Beit known that I, CHARLES C. ROSE, a citizen of the United States, residing in Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Gates for Coal- Stoek Trestles, o'f which the following is a specification.
My invention consists in certain new and useful improvements in gates for coal-stock trestles, and will be fully and clearly hereinafter described and claimed, reference being had to the accompanyingdrawings,in which- Figure l represents a sectional elevation of a coal-holding bin, showin ga side elevation of my in vention connected therewith, and an end View of a car in position for receiving a load of coal therefrom. Fig. 2 is a side elevation showing a slight modification of the operating mechanism for opening or closing the gate. Fig. 3 is a detached front elevation of the gate. Fig. i is a detached front elevation of the grooved pulleys connected with the operating mechanism.
The object of my invention is to produce a gate for coal-trestles or for other similar purposes that can be easily operated or opened or closed byhand. Heretofore it has been very difficult to operate such gates, owing to the great vertical pressure of the coal or other equivalent material upon the gate. This objection I overcome by locating my gate in such a position as to relieve it almost entirely from the perpendicularpressure produced by the weight of the material resting upon it, and so that it is subjected' to a slight lateral pressure only.
In said drawings, 1 represents an ordinary coal-bin, which may be of any well-known forni or size. At the bottom of the bin is an inclined opening or chute, in which the gate 2 is mounted on a shaft 3 in suitable bearings at the end of the inclined chute, in such yposition as to relieve. it from the vertical pressure of the coal. (See Fig. 1.) The face i of the gate is in the form of an are of a cirele whose center is the shaft 3, and as it is located to one side, under or nearly under the door or plate it is subjected to verylittle pressure, and can be easily turned to open or close it by hand. To the upper rear portion of the gate are two projecting lugs 6, and between them is pivoted the end of a rod 7 (see Figs. l. and 3) by a pin S, having its opposite end pivoted to the end of an angular arm 9 by a pin 10. This arm E) is mounted on a shaft or pin 11, so as to turn easily, and is secured in any well-known way to the under side of the coal-bin-to the beam 12, for instance. Adouble-grooved pulley 125, hav# ing grooves a and b, is mounted on a shaft 14.-, (see Figs. 1 and 4,) and secured so that its periphery will be in or nearly in a vertical line with the opposite end 15 of the arm 9. (See Fig. l.) To the pin 10 (or to that end of the arm) is secured the end of the chain 16, which passes over the pulley 13 in one of its grooves, and then, passing down vertically far enough to be within convenient reach of the operators hand, is provided with a hand-stirrup 17. To the end 15 ot the arm 9 is secured another chain 1S, which passes up and over the pulley 13 in its other groove, and then passing down is providedy with a hand-stirrup 19 for operating it. From this construction it will be seen that a pull downward on the stirrup 17 will move the rod 7 in the direction of the arrow V and turn the gate in the position shown by the dotted lines 20, (see Fig. 1,) and thereby open it and permit the coal or other material to flow out into the car, as shown, after which a pull on the stirrup 19 will reverse the operation and close the gate or bring` it into the position shown in Fig. 1.
In the modification shown in Fig. 2 the arm 9 is dispensed with and the chains 16 and 1S are secured directly to the bar or rod 7. The chain 1G passes up over in one groove of the pulley 13, and is secured to a lug 21 on the bar 7, and the chain 1S passes up over from the other side of the pulley 13 in the other groove, and is connected by a lug` 22 on the rod 7. From this construction it will be obvious that the rod 7 may be moved longitudinally back and forth by pulling on the handstirrups 17 and 19. In this case the rod 7 would have to be supported in slideways 23 21 or the equivalent thereof.
v The sides of the gate are provided with a IOO pivot-edl to the gate, and Chains having handstirrups at their lower ends for operating them, and their upper ends passing over the pulley in opposite grooves and in opposite directions and connecting with thev rod secured to the gate for opening and closing it, substantially as described.
