JOSEPH LA BRECHE VIGER, or MONTREAL, QUEBEC, CANADA.
SPECIFICATION forming part of Letters Patent No. 278,976, dated June 5, 1883.
Application filed December 4, 1882. (No model.)
To all whom, it may concern:
Be it known that I, J. LA BRECHE VIGER, of Montreal, in the Province of Quebec and Dominion of Canada, have invented a new and Improved Magnetic Separator, of which the following is a full, clear, and exact description.
-My machine is intended to separate ironsand from common sand, the object being to obtain as large a percentage as possible of the ore free from other sands.
The invention consists in an endless traveling apron combined witha series of magnets placed at an inclination, so that as the sand is I fed to the side of the apron the magnetic particles will be retained thereon and carried forward to the discharge end, as hereinafter described and claimed.
I Reference is to be had to the accompanying 2o drawings, forming a part of this specification,
in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of my improved machine. Fig. 2 is an end view of the same.
Fig. 3 is a detail section of the feeding-hopper.
At the ends of an upright frame, A, of rectangular form, are fitted rollers B B, around which passes an endless apron, C, of cloth or other suitable material, the apron also passing around a third roller, D, which is designed to be adjustable for tightening the apron. Behind the flat side of the apron is fitted aboard, E, that is formed with grooves or slots extend ing from one roller B to the other roller B at 3 5 an angle of about thirty-five degrees. In the slots or grooves of this board are magnets a, that may be either permanent or electro mag- I nets, and they are so placed that their poles are in contact, or nearly so, with the inner sur- 0 face of the apron C. Upon the frame A is a hopper, F, provided in its lower portion with an endless apron, b,which acts to carry the material and deliver it to tubes 61, that terminate on the face of the apron in front of the magnets at the higher ends of the series. One of the rollers B is fitted for operation by means of a belt, 6, passing from a driving-pulley, f, and the pulley f is also connected by a belt to a shaft, 9, that operates the feed-apron b.
In the operation of the machine, the material, being placed in the hopper F, is conveyed by the tubes (1 anddischarged against the face of the apron. The magnetic portions will adhere to the apron along the rows of magnets, and thus be carried to the opposite end'of the apron, and at the same time moved downward thereon by theinclination of the rows of magnets. The non-magnetic material will fall immediately, while the magnetic materials will be retained until they reachthe lower magnets, when they will fall in a separate pile. The frame A is fitted with suitable supports for retaining it in an upright or more or less inclined position.
Having thus described my invention, I claim as new and desire to secure by Letters Patent In magnetic separators,the upright or nearly upright board E, 'having the downwardly-inclined rows of magnets a, in combination with the endless moving apron 0, arranged in close 70 contiguity with the poles of the magnets, and hopper F,having spouts d, feeding the material to the apron or carrier Q opposite to the upper ends of the rows of magnets, substantially as and for the purpose set forth.
