ORE-FEEDER.
SPECIFICATION forming part or' Letters Patent No. 322,716, dated July 21, 1885.
I Application filed January 22, 1883.
To all whom it may concern:
Be it known that I, J osrrUA HENDY, of the city and county of San Francisco, State of California,have invented an Improved Ore-Feeder; and I hereby declare the following to be afull, clear, and exact description thereof.
My invention relates to certain improvements in ore-feeders; and it consists in the combination of devices hereinafter described and claimed.
Referring to the accompanying drawings for a more complete explanation of my invention, Figure lis a perspective view of an ore-feeder with my improvements attached. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is an enlarged view of the wheels O and P. Fig. 4 is a detached View of the oscillating wheel O, and showing the clutch arms Q. Fig. 5 is adetached View of the wheel P, showing the hub and springs.
In the drawings, Ais the frame of the feeder supporting a hopper, B, into which the ore is received; and C is a circular disk or table having a central shaft, D, turning in a box, D', and standing at such an angle that the upper surface of the table will be inclined downward from the rear of the hopper toward the front or discharge edge.
E F are guides, between which the ore passes and bywhich it is directed to the proper point of discharge.
The table is rotated by a bevel-pinion, H, secured to a horizontal shaft, I, and engaging a bevel gear-wheel, J, formed with or fixed to the lower side of the inclined table, as is fully shown in a patent granted to Thomas Cochrane March 17, 1874, N o. 148,597. The shaft I has a bearing at one end in the frame of the machine, and at its opposite end in Ya sleeve, I', projecting from the box D'. Upon the outer end ofthe shaft I is fixed aclutch mechanism, by which the shaft is rotated and the table turned by the action of the droppingstamp.
A collar or equivalent device upon the stamp-stem strikes the end of the lever L ora rod, L', connected with it and extending upward from it. This lever is connected by a pitman, M, with an arm, N, which projects from the rim of a wheel, O, which turns loosely upon the shaft I. To one side of this wheel is another wheel, P, which is keyed fast to the (No model.)
shaft. (See Figs. 3, 4, and 5.) The wheel P has a hub, o, provided with sockets o' to receive the innerends of arms Q. These arms are placed tangential to the shaft I, and are of such a lengthV as to bind against the inside of the rim O when itis moved in one direction, and thus. turn the wheel p in the same direction 5 but when the wheel O turns back these cams are held by springs q, so as to slide along the rim of Wheel O without binding. The rim P is prevented from rotating backward by a curved block, G, -which is pressed against it by a spring, K, producing an intermittent forward movement of the wheel P, shaft I, and feeding-table.
The constant movement of the clutch-arms Q will in time wear the ends into points, which will indent the rim of wheel O so that it will be notched and irregular, and the delicacy of the feed-movement will be impaired. To avoid this, I form blocks R with their outer faces curved to fit the inner curve of the rim of wheel O, and their inner faces fitted to rcceive the ends of the arms Q, so that the blocks R act as feet,with a broad surface to bear upon the inside of the rim and prevent wear. I make no claim to this feature, as I desire to make a separate application therefor.
In order to return the lever L to the point of action after each stroke of the stamp, and with it the oscillating Wheel O, I employ an arm, S, one end of which is connected by a link, T, with the lever-arm N. The opposite end of arm S .engages ascrew-bolt, u, fixed in the frame timber, which bolt extends up through a hole in the plate near its bearing end.
A block of rubber, V, is adjusted upon the bolt by a nut, o, at the top, so as to give any desired elastic pressure upon the arm S, and thus return the various parts with a positive motion after the action of the stamp-stemiupon them. Y
W is a block, preferably of wood, upon the top of which the arm N rests when relieved by the action of the spring. This block Wts into an opening in the top of a slotted box, X, through which a wedge, Y, passes, as shown This wedge is operated by a screw,
Z, and serves to raise or lower the blocks W to suit any degree of movement of the feed apparatus which may be desired.
By this mechanism I am enabled to control the movement of the rotary table and the amount of ore fed Very accurately, and to adjust and regulate the parts to the best advantage.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In an ore-feeder, the inclined rotary table C, the shaft D, driving-gear clutch mechanism, levers L and N, and pitman M, in combination With the plate S, link 'I, and the elastic adjustable spring or buffer V, substantially as herein described.
2. In an ore-feeder, the inclined table, clutch mechanism, levers L and N, and means for operating the same, in combination with the block IV, box X, adjusting Wedge Y, and screw Z, substantially as herein described.
