No. 392,562. `Pateaatd Nov. 6, 1888.

ORE=FEEDER.
SPECIFICATION forming part of Letters Patent No. 392,562. dated November 6, 1888.
Application filed March 30, 1887.
To all whom it may concern,.-
Be it known that I, FRANK A. HUNTINGTON, of the city and county of San Francisco, State of California, have invented an Improvement in Ore-Feeders; and I hereby declare the following to be a full, clear, and exact description ofthe same.
My invention relates to a device for feeding ore to stamp or other crushing mills, or for feeding any material where it is necessary t0 have a regular discharge; and it consists in certain details of construction, all of which will be hereinafter claimed, and more fully described by reference to the accompanying drawings, in which- Figure 1 is a vertical section taken through the hopper, the table, and the operating-cam. Fig. 2 is a front View of the apparatus, showing the adjustable cam -and adjusting arm or bar.
A is a hopper, which is suitably supported upon a frame-work, and this may either be stationary or mounted upon wheels, so as to be moved from place to place. In the present case I have shown this hopper with sides tapering or inclining toward each other and the back inclining toward the front, which is nearly or quite vertical, so that the ore is concentrated at the bottom and is delivered upon an inclined table, B. This table extends beneath the bottom of the hopper, having such an inclination as to discharge to the front. An adjustable gate, O, is fitted above the front end of the table, so as to control the discharge in the usual manner. This table has its front end supported upon a rocking bar, E, and its rear end upon a similar rocking bar or link, F, these two being fulcrnmed or pivoted at the bottom and having their upper ends connected by half-round sockets or by links or other suitable devices with the bottom of the table, so that as they are oscillated backward and forward the table slides beneath the hopper and in line with the bottom. The back of the hopper has agroove or socket, into which the upper edge of a plate, b, tits, or it may be otherwise hinged or connected thereto, and the lower edge of this plate rests in a similar groove in the surface of the table, so that as the table moves slowly back and forward the lower edge of this plate is moved with it, the upper edge turning in the groove or channel Serial No. 233,061. (No model.)
which forms the hinge or fulcrum. The ore passing out ofthe hopper falls onto the front end of the table. As the table moves forward it carries this ore along, allowing more of the ore to come out from the hopper, and as it is drawn backward the ore is prevented from moving back with it, and this causes the ore which is already on the front of the table to drop off as the table moves back. The next motion forward carries the ore toward the front and more falls in behind it from thehopper and the discharge becomes steady and continuous with each oscillation of the table.
In order to oscillate the table and regulate its oscillations, the link F has an oval slot, G, made in its center, and through this a shaft,
H, passes, having a cylinder, I, iiXed to it.v
This is made to act as an eccentric by boring or coring it from the center of one end to a point near one side at the opposite end, so that as the shaft H is rotated by any suitable power if the cylinder is moved so that the point where the shaft is in the center ofthe cylinder is within the slot G there will be no motion conveyed to the link or rocker arm F, but by moving the cylinder along the cam until that portion which is eccentric to the shaft is within the oval slot G4 the greatest throw will be given to the oscillating link and the table will be given the greatest motion. By sliding the cylinder along the shaft any degree of throw may be given to the table between this point and that of no throw, the adjustment of the cylinder being accomplished at any time without stopping the operation of the machine. In order to move this cylinder along the shaft a collar, J, surrounds one end of it, and an arm, K, projects to one side, having an arm or rod, L, extending out at right angles from it and passing through a guide, as shown at M. The arm L has a suitable handle by which it-may be moved, so as to cause the cylinder I to slide upon its shaft H, and notches N upon the bar L will engage with a catch, so as to hold the cylinder I at any desired point. A screw or cam may be employed in place of the notched bar, the action being essentially the same. The shaft H may be simply a rough square shaft passing through the cylinder I, which is sufficiently loose to slide back and forth upon it while being caused to rotate by the rotation ofthe shaft, or the shaft may be turned and IOO have a feather upon which the cylinder slides; but the first mentioned is the cheapest construction. By this mechanism it will be seen that the feed may be regulated to any degree of nicety by altering the throw of the eccentric and varying the movement ofthe table.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
l. An ore-feeder comprising a stationary hopper and an inclined table beneath upon which ore is deposited from the hopper, links or arms upon which this is supported, one of said links having on oval slot through it, a drivingshaft, and a cylinder mounted obliquely to the axis adjustable longitudinally thereon and extending through said slot, whereby the throw may be changed while the feeder is in operaL tion, substantially as herein described.
2. The hopper or receiver having a groove 2o or socket in its rear and the reciprocating table moving beneath said hopper and having a groove or socket in its upper surface, in combination with a plate interposed between said hopper and table, with its upper and lower ends engaging the grooves or sockets therein, substantially as described.
In witness whereof I have hereunto set my hand.
FRANK A. HUNTINGTON.
