which it appertains to make and use the same.
My invention is an improvement in magnetic separating apparatus; and it consists in the novel features hereinafter described, reference being had to the accompanying draw- :5 ings, which illustrate one form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.
Referring to the said drawings, Figure 1 repzo resents a side elevation, partly in section, of
an apparatus embodying my invention. Fig. 2 represents a horizontal section of the same on line 2 2 of Fig. 1. Fig. 3 is an enlarged view of a part of the rotating separating-disk,
showing the course of electric current diagrammatically.
A represents a rectangular frame which supports the various parts of the apparatus and which is preferably made of wood.
B is a conveyor consisting in this instance of an inclined longitudinally-reciprocating shallow trough or shaker provided with shallow sides I) and an end piece I). The trough or shaker B is supported from the frame'A by hangers b b of any-preferred construction permitting the longitudinal movement.
0 represents the driving-shaft, mounted in bearings secured to the frame and provided with an eccentric o, eccentric-strap c, and ec- 40 centric-rod 0 which is secured to the trough for imparting a reciprocating movement thereto. The trough or shaker is preferably supported in an inclined position, as shown, and adjacent to its upper end I provide a hopper D, secured to the frame and having at its lower end, immediately above the conveyor, a stirring-roller E, consisting of a shaft mounted in the hopper and provided with pins or projections e. The shaft of the stirring-roller Serial No- 713,778. (No model.)
is provided, outside the hopper, with a driving-pulley e for operating the stirrer.
F represents a vertically-disposed shaft mounted in suitable bearings ff in the frame and arranged perpendicular to the conveyer B. This'shaft is provided with a bevel-gear f, meshing with a bevel-pinion g on a horizontal counter-shaft G, also mounted in bearings secured to the frame A and provided with a band-pulley g, to which motion is imparted by a belt from a pulley c on the driving-shaft O. The shaft F is provided with a horizontally-disposed disk or plate H, preferably formed of wood or other non-conducting material, arranged parallel to the conveyer and having a portion overhanging the same and a portion extending laterally beyond the edge of the conveyor, as shown. This disk H is provided with a series of electromagnets I, preferably arranged in afcircle around the disk H, as indicated in Figs. 2 and 3, by poles of the magnets extending to or below the lower face of the disk, so that as the disk revolves the poles pass over the conveyer and very close to the same.
I provide means for supplying an electric current to the magnets while they are above the conveyer, certain of the magnets at one side of the conveyer being cut out of the circuit, so that as the disk revolves the magnets will attract metallic particles while passing over the conveyer and will carry them laterally out of line with the conveyer, when they will be cut out of circuit and will drop the metallic particles, which fall into a suitable receptacle. In this instance I have shown the magnets arranged in pairs and the disk H, provided with a circuit-breaker for each pair of magnets, constructed in the following manner, and, as all the circuit-breakers are identical'in form, I will describe but one of them.
The disk H is provided with a stationary contact K, preferably in a radial line therewith, which is connected to one magnet of the pair by wire 1, the two magnets of each pair being connected by wires 2 2. I
K represents the movable contact, pivoted on a pin or stud It to the disk and having its free end adapted to engage the stationary contact K. The movable contact K is provided with an arm extending at an angle thereto, and the portion of the arm K adjacent to the pivot-pin 7a is provided with a shoulder U.
K represents an operating-arm pivoted upon the stud 70 independently of the movable contact and provided with a frictionroller 70 at its outer end and with a lug or projection k adjacent to the pivot pin or stud adapted to engage the shoulder W. The arm K is connected to the arm 70 of the movable contact by a yielding connection, in this instance a coiled spring 7t, and a second spring 7r connects the arm K with a stationary pin, in this instance secured to an arm k, which is rigidly secured to the pivot-pin 7c and is incapable of movement with respect to the disk.
From the foregoing description it will be seen that the tension of spring 79 drawing on arm K and in turn drawing on arm 7c through spring k will normally hold the movable contact K in engagement with the fixed contact K. A wire 3 connects one magnet of each pair to the pivot-pin 7c of its respective switch or contact-breaker.
L represents a curved bar,preferably formed of wood or other non-conducting material,c0ncentric with the axis of disk H and secured to the frame A by brackets Z Z, so as to be in position to be engaged on its inner face by the friction-rolls 70 of the circuit-breakers. This bar is provided at each end with metallic conducting-strips Z Z provided with bindingposts Z Z respectively, said strips extending along the inner face of the bar, as shown in Fig. end (preferably near the inner ends of the said contact-strips) with a cam-grade Z, the central portion of the bar being nearer the axis of the disk than the end portions. As the diskis revolved the friction-roller of each circuit-breaker will be brought into engagement with the metal contact piece or strip Z and will take current therefrom, as hereinafter described. As the roller passes along the strip it will roll up the cam-grade Z thereby moving the operating-arm K of the circuit-breaker inward, forcing the lug k thereof into contact with the shoulder 70 on the movable contact K and moving the latter away from its fixed contact K, thus breaking the circuit. The roller then passes along the central non-conducting portion of bar Land is insulated from both of the contact-strips Z Z until it passes onto strip Z and rolls down the cam-grade Z at the other end of the bar L and allows the spring 7a to bring the movable contact again into engagement with its fixed contact. The course of the current is indicated somewhat diagrammatically in Fig. 3, in which but half of the disk II is shown.
M represents the battery or other source of electrical energy, from which the current passes over wire 4 to binding-post Z, thence to contact-strip Z thence through the fric- The bar L is also provided at each tion-roller k and arm K of one of the circuitbreakers (indicated by X on Fig. 3) to its pivot-pin 7t, thence on-wire 3 to one of the magnets of the pair connected with said circuit-breaker, thence on wire 2 to the other magnet, thence on wire 1 to the fixed contact K of the next circuit-breaker to the right, thence through the movable contact K thereof to its pivot-pin, thence to one of the magnets, and so on around the portion of the disk which overhangs the con veyer to the circuitbreaker (indicated by Y, Fig. 3) whose friction-roll is in engagement with the contactstrip Z, through said circuit-breaker to the said contact-strip, and over wire 5 from binding-post Z to the battery M. It will be seen that all of the circuit-breakers lying between X and Y have their friction-rolls engaging the portion of the bar L between the camgrades Z Z and the said circuit-breakers are therefore open and the magnets connected therewith are cut out of the circuit temporarily. I do not wish to limit myself to the use of this form of circuit-breaker.
In order to prevent any metallic particles from adhering to the poles of the magnets While they are cut out of circuit, I prefer to arrange a brush N, secured to a support n, attached to the frame, which brush sweeps the under side of disk H and will positively brush off any particles which might have a tendency to adhere. The material dropped by the magnets falls into a box 0 or other suitable receptacle.
The driving-shaft is provided with a bandpulley 0 by means of which the machine can be driven from any suitable source of power.
In operation the material is fed into the hopper and the machine is placed in motion. The material will fall gradually upon the conveyer-4n this instance the shaker-and be moved longitudinally thereof toward its lower end, passing beneath the disk H. As the disk revolves over the material the metallic particles thereof will be picked up by the magnets, carried laterally out of line with the conveyer, and dropped or brushed off, as heretofore described.
What I claim, and desire to secure by Letters Patent, is
