FEED-REGULATOR BOR .ORE-FEEDERS.
SPECIFICATION forming part of Letters Patent No. 745,169, dated November 24, 1903.
` Application filed April 23, 1902. Serial No. 104,280. (No model.)
means of which the ore can be evenly fed to the crusher or the like.
I will describe an ore-feeder embodying my invention and then point out the novel featu res in the appended claims.
Reference is to be had to theaccompanying drawings, forming a part of this specification,`
in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of an ore-feeder embodying my invention. Fig. 2 is a rearelevation thereof. Fig. 3 is a plan View. Fig. L1 is -a detail showing means for operating the feeding-cylinder, and Eig. 5 is a sectional detail showing the feed-regulator.
The ore-feeder comprises a cylinder 1,
mounted on a shaft 2, which has its bearings in the upper portion of a frame 3. This cylinder is provided at its ends with outwardlyextended annular flanges 4, and outward of these flanges are cylindrical ledges 5. Mounted to rock on the shaft 2 at oppositeends of the cylinder are levers 6, which are connected at the front and provided with a handle 7.
On the rear ends of the levers 6'are adjustably arranged balancing-weights 8.v Each lever is provided with a block 9, which extends across the cylindrical ledge 5, and the inner and outer walls vor sides of this block are inclined upward and outward, so that the upper portion of the block is at a greater distance from the cylindrical ledge 5 than is the lower portion, and placed between the blocks 9 and the portions 5 of the cylinder are bearing-balls 10. These levers 6 are designed to impart a step-by-step rotation to the cylinder-that is, by moving the handle 7 up and down the downward movement of said handle will cause of course the rearward portions of the levers to move upward-andduring this motion the balls 10 will crowd in between the blocks 9 and the cylinder and by friction cause the cylinder to rotate as described. Upon a reverse movement the wider portion of the space between the blocks 9 and the cylinder will receive the balls, and thus relieve the frictional engagement and prevent a reverse rotary'movement of the cylinder. The set-screw 6?, lattached to the rear part of the frame, regulates the space through which the handle or lever travels,thus regulating the rotary movement of the cylinder. As the balls are of varying diameters, they will all bear upon the cylinder, and thus provide a comparatively large friction-surface.
Arranged above the cylinder is a hopper 11, the rear wall of which is inclined, as shown, and the bottom of the front Wall is provided with an opening 12, which is controlled by a gate-valve 13. This gate-valve slides against the inner side of the front wall of the hopper and is held as adjusted by means of bolts 12a, passing from the valve through slots in said front wall. The side walls ot' the hopper are conformed to the shape of the cylinder and rest thereon. Attached to the hopper are standards 14, the lower ends of which are forked to engage upon the shaft 2', so that the hopper may be rocked back and forth or adjusted. The adjustments'are made by means of a screw 15, operating in a nut 16, attached to the machine-frame and having a pivotal or swinging connection 17 at the upper end with the rear Wall ot' the hopper. The front Wall is so inclined that as the hopper is carried rforward of the vertical center of the cylinder IOO or outlet of the hopper. The hopper is made adjustable for the purpose ot' regulating the feed from the hopper, and the sliding gate of the hopper is also made adjustable for the same purpose. As the hopper is carried rearward of the vertical center of the cylinder the effective component of gravity becomes inoperative, thus decreasing the quantity of matter nding its escape through the gate of the hopper. When the hopper is carried forward of the vertical center, the feeding component of gravity becomes more operative, hence causing au increase of the amount of matter passing through the outlet. The hopper being patterned so, its front Wall approaches the perpendicular as the hopper is carried forward for the purpose of further increasing the eifect of gravity. This is necessary if the matter beingfed is adhesive, as it is if it be wet, full of clay or other sticky matter, which is often the case. Dry matter will be prevented from falling directly into the chute by the sliding gate of the hopper and by carrying the hopper rearward and by decreasing the rotary motion of the cylinder. Hence with the sliding gate, oscillating hopper, and speed regulating of the cylinder we have an accurate adjustment of the amount of matter fed, whether it be dry or wet, coarse or fine, adhesive or not.
Having thus described my invention, I
claim as new and desire to secure by Letters Patent-#- 1. In an ore-feeder, a frame, a cylinder mounted to rotate in the frame, annular flanges at the ends of the cylinder, cylindrical ledges at the outer sides of the flanges, levers mountedto rock .at opposite ends of the cylinder, blocks carried by the levers and extended across the cylindrical ledges, the sides of the blocks adjacent to the ledges being inclined upward and outward, a series of bearing-balls arranged between the blocks and ledges, the said balls being of varying diameters, and a hopper arranged above the cylinder, substantially as specified.
2. In an orefeeder, a frame, a cylinder mounted to rotate in the frame, levers mounted to rock at opposite ends of the cylinder, blocks carried by the levers and divergent from the cylinder from the lower end upward, a series of bearing-balls arranged between the blocks and cylinder, the said balls being of varying sizes, and a hopper over the cylinder, substantially as specified.
YIn testimony whereof I have signed my naine to this specicatiou in the presence of two subscribing witnesses.
