To all whom, it may concern:

Be it known that I, GEORGE LEWIS HOLMES a citizen of the United States, residing atChicago, in the county of Cook and State of Illinois, have invented a certain new and'useful Improvement in Gates and Chutes for Coal or Ore Pockets, of which the following is a specification.

My invention relates to gates and chutes for coal or ore pockets, and has for its object to provide certain new and useful improvements.

Figure 1 is a frontview. Fig. 2 is a crosssection on line 2 2, Fig. 1. -Fig. 3 is a horizontal section near the lower part, Fig. 2.

Like parts are indicated by the same letter in all the figures.

A is the bin or pocket, which consists, for example, of the siding and the vertical beams B B and other necessary and associated parts. This pocket is arranged with an opening C, preferably lined, as indicated at C, and there is an inclined way C leading into and through the opening. The lower end of this inclined way is properly supported on the cross-beams C and C. The opening on the exterior side is provided with an outwardly projecting downwardly-opening hood composed of the plates D D, firmly fixed in position.

E is a gate having the arc-shaped cut-off portion E, the flat chute portion E the end frame-pieces E E, and the curved portion E, which passes around the shaft, and it is pivoted on the shaft E, which is supported in the bearings E". On the outer end of this shaft E is an arm F, attached tothe. link'F, which is in turn pivoted at F to the short arm F which at one end 'is pivoted at F to the side of the hopper-pocket. F" is the other end of said arm, pivoted at F to thelink F and suspended midway by the loop F, suspended from the rope F, which runs over a pulley at E", which is mounted in thebracket F, and on the other end of this rope is suspended the coun terbalance-weight F". From the outer extremity of the arm portion F depends the rod G, provided with the cross-bars G G. These parts all stand normally in the position indicated. By pulling down on the rod G the arm 5 F F tends to assume a horizontal position end of the rope carries the weight J Serial No. 99,648. (No model.)

and is lowered at F thus lowering the-link F and moving the arm F and rocking the shaft E so as to bring the gate into' the position indicated in dotted lines. The fiat chutelike portion E of the gate E is such that the material escaping overthe top of the gate E is carried away on the chute-like incline E J is an outer chute open at the top, the sides of which overlap the sides of the hood D when the pipe J is raised. It is provided below with the chain J and above with the rope J passing over the pulley J on the bracket J of the pocket-frame. The otllier Tiis chain and rope are preferably secured to the outer extremity of the chute J, which is in the form of a downwardly-curved portion J 6 and is provided with the handbar J. The upper end of the chute or spout is journaled on the bushing J which projects from the bearing E and through which passes the shaft E The spout is thus not directly supported on the shaft.

The parts are shown in the position which they would occupy when the supply of coal has been cut off and the last portion of that supply has just passed onto the locomotive. The next step will be to raise the chute J in the position shown in dotted lines, which is done by raising it up by means of the handbar J In this position the gate operates as a stop to prevent the further flow of the material through the hood and chute; but the last material, as the flow is being interrupted, instead of falling ofl the top of the gate slides down the incline E and out through the chute J. Theparts are manipulated respectively by the weights and their connections. When it is desired to furnish a supply of coal to the locomotive by means of the chain J, the chute should be drawn down against the weight J 5 in the position shown in full lines. Then by manipulating the rod G by either of the bars G G the gate will be thrown down intothe position shown in dotted lines, as indicated above, this action-being counterbalanc'ed by the weight F The material can now How out over the incline E down the chute J. When a sufiicient supply has been obtained, the rod G may be moved up wardly, whereupon the parts associated with the gate will assume the position shown in full lines and the stream of material will be cut ofl. It will be observed that the parts are so located that this cut-ofl? takes place notdi-w rectly at right angles to the flow, but in the direction of the flow, so that the danger of crushing the material between the outer extremity of the gate and the hood is minimized. The gate itself is open near this point, as indicated in Fig. 1, so as to reduce the danger of such crushing action. After the last of the material has escaped the chute J can be thrown up into the position indicated in Fig. 2

in dotted lines. It will also be observed that in my construction the gate is supported on a shaft or rod and not on mere light side pins. This is important as obviating the giving and moving of the parts, which so often results in binding. It will also be seen that the gate is located so that its supporting-point is beyond it easy of access for adjustment or repairs. By placing the gate-supports in the position Ihave shown it is possible .to use a rod, because it is placed below the line of travel of the material, while under other conditions it would impede the flow. The spout not being supported on the shaft, but on the bushings associated therewith, is in much less danger of causing binding or cramping of the parts. It is desirable to have the gate as close to the pocket as possible, and by my arrangement, having the gate work on the arc of a circle it cannot enter the edge of the opening, and thus there is left room for a substantial cross-brace in the frame of the pocket and also for the operation of the movable gate, substantially or largely within the line of such pocket-frame. The lower hooded end of the spout prevents the coal from being thrown out at this point.

r I claim In a gate and chute for coal or ore pockets, the combination of a gate to cut off the flow of coal with a transverse rod below the bottom of the discharge-way, said gate pivoted on such rod, and an outer spout pivoted concellltric with but on pivots independent of the ro GEORGE LEWIS HOLMES.
