HENRY c. ELAsDEL, oE OAKLAND, CALIFORNIA.
ORE-CONCENTRATOR BELT.
SPECIFICATION forming part of Letters Patent No. 416,663, dated December 3, 1889. Application filed September 6, 1889. Serial No. 323,160. V(No model.)
To all whomjt may concern:
Be it known that I, HENRY G. BLAsDEL, of Oakland, Alameda county, State of California, have invented an Improvement in Ore-Concentrator Belts; and I hereby declare the follow ing to be a full, clear, and exact description of the same.
My invention relates to that class of belts which are used as concentrating-surfaces for ore-separating machines of that type known as the endless-belt concentrator, and my invention consists in the novel arrangement of the side iianges of the belt, hereinafter fully described, and `specifically pointed ou in the claim.
The object of my invention is to provide a concentrator belt of this class with side flanges, which are arranged in such a manner that in passing over the drums or rollers of the machine they will conform in the best manner to their change of direction, and will also better conne the charge upon the surface of the belt. y
Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a perspective view of a concentrator of this class. Fig. 2 is a cross-,section of my belt. p
A is the frame of the machine, and Bis the roller at its head,over which the endless belt C passes. D represents, generally, the water and ore distributers by which the charge is delivered upon the belt.
In Fig. 2 will be seen plainly the construction of my belt. It is to be made of any suitable material, preferably of rubber, and is to be provided with side flanges c. These fianges are so arranged with relation to the belt as to occupy upwardly-converging planes, so-that they meet the surface of the belt at an acute angle. These flanges are to be made of suitable material, either separate from the belt or integral with it, and they are provided on their inner sides with small re-enforcing portions c', which in the case of rubber belts serve as springs for holding` the flanges up to their proper position.
In concentrators of this class the ore is fed upon the surface of the belt, which has impart-ed to it what is known as an uphill travel.
The belt is set at a slight inclina# tion, and it moves up the incline and around the head or drive roller of the machine. The ore pulp being deposited upon the surface of the belt, the lighter and worthless material is washed down by the water over the foot of the belt, while the heavier and precious material clings to the surface of the belt and is carried up over the head roller by it and washed off into a suitable tank below.
The belts of this class of machines have heretofore been provided with side an ges for confining the charge to the surface of the belt. These anges are generally made or formed to occupy a vertical plane with reference to the belt-surface, and in the case of rubber belts are formed integral with the belt. The disadvantage of this arrangement of the iiange is that in passing over tho end rollers ot' the machine they have a tendency, espe- .cially in cold weather, to crack, as they do not yield sufficiently to the change of direction in passing around the rollers. In some instances these iianges have been lnade outwardly flaring, and while in such a case they better conform to the change of direction they do not confine the charge to the belt sufficiently well. In my construction my flanges have no tendency to crack,as in passing over the rollers they lie down on the belt. They thus conform to the change of direction, and at the same time they better confine by their inwardly-inclinedv direction the charge of ore pulp to the belt.
Having thus described my invention, what I claim as new, and desire to secure by Letters HENRY G. BLASDEL. Vitnesses:
