UNITED STATES PATENT OFFICE.
LEE D. CRAIG, OF SAN FRANCISCO, CALIFORNIA.
ORE-F'EEDER.
SPECIFICATION forming part of Letters Patent No. 426,245, dated April 22, 1890.
Application filed February 25, 1890. Serial No. 341,762. (No model.)
To all whom it may concern.-
Be it known that I, LEE D. CRAIG, of San Francisco, in the county of San Francisco and State of California, have invented a new and useful. Improvement in Ore-Feeders; and I do hereby declare that the following is a full, clear, and exact description of the same.
My invention is an improved feeding mechanism for feeding ore into a mill. It is of that class in which the material is moved from the hopper by means of an endless band pulley G.
passing over pulleys or sprocket-wheels.
My lnvention is designed to provide an apparatus of this class suitable to act for a feeder for ores, as above specified, or feeders of that general class, and my object, as compared with ore-feeding mechanisms heretotore known, is to produce a simple and effective mechanism and one which at the same time will operate with certainty and feed uniformly and evenly.
My invention is illustrated in the accompanying drawings, in which.
Figure 1 shows a plan view of the apparatus. Fig. 2 shows a vertical cross-section 011 line a: as of Fig. 1. Fig. 3 shows a side elevation of the endless band and. hopper, one side of the casing or box being removed.
.In the drawings, A represents the hopper, one side of which is vertical and the other inclined. By the vertical side of this hopper is a box B, forming a channel in which is arranged an endless-chain conveyer D. The chain has open links b, through which the ore can fall, and runs upon sprocket-wheels E F, one of which is provided with a driver- The chain runs on the bottom of the box 13, and with one edge closes against the vertical wall of the hopper. The chain moves in the direction of the arrows 1. At the bottom of the hopper is an opening a, made in the vertical wall thereof, and arranged to discharge the ore or stone upon the chain while it is passing over the bottom of the box I3. The ore or stone is ordinarily in fragments not larger than a walnut and from that size down to smaller. The apparatus described permits the passage of this material through the opening a onto the chain. As the chain passes it falls into the open links and is swept along over the bot tom by the solid parts of the chain 1) until it reaches an opening fin the bottom, where it falls through the open links into a hopper or chute H, whence it is conveyed to the mill. The size of the opening a may be varied in any suitable way well known to regulate the amount of material fed to the chain, which receives in each open link equal amounts. As the chain moves on, I find it better to discharge the material on the lower part of the chain instead of the upper. In order to agitate the material in the hopper, I have provided a lever K, which is pivoted on a crossbar L. The lower end of the lever projects through the opening a, and extends over the chain, so as to be struck by the solid por tions as they pass in succession. The upper end of the lever is connected to the side of the hopper by a lateral spring M, and as the chain moves the lever is drawn in one direction by the solid portions, and when it has passed over such a portion it is snapped back by the spring, and thus the material in the hopper is kept constantly stirred.
In order to prevent any of the material from resting on the solid portions of the chain or adhering thereto and passing to the sprocket-wheels, I provide a brush N, arranged over the chute II, and this cleans the chain as it passes thereunder.
I claim as my invention 1. A hopper having its discharge-opening at one side, a stationary bottom plate outside the hopper and below the level of the opening therein adapted to receive the discharge from the hopper, and a feed-chain arranged above the bottom plate, substantially as described.
2. In combination with the chain and a hopper having a lateral opening arranged to discharge upon the chain, an oscillating lever K, pivoted within the hopper and extending into connection with the chain, with means for returning it, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
LEE D. CRAIG.
