MAGNETIC SEPARATOR.

i ,isassa To all whom it may concern: Be it known that I, DAVID L. RAND, a citizen of the United States, residing at Ayr, in the county of Cass and State of North Dakota, have invented a new and useful Improvement in Magnetic Separators, of which the following is a specification.

This invention -relates to a feed regulator' comparatively wide and shallow stream and to regulate the flow of such stream," after which the grain is again returned to the feed spout leading to the mill.

In the accompanying drawing: Figure 1A is a perspective view of the device. Fig.v 2 is a detail sectional view illustrating the manner of mounting a feed regulating gate.

In the drawings 1 represents -a vertically arranged pipe which may be either a part of the `regular grain delivery spout, or may be an independent section connected to said spout. The grain delivery.' spout is continued as indicated at 2, the said spoilt when my device is applied being interrupted, and the lower portion being oset with respect to the upper portion, my device being interposed between the sections l and 2. The

' pipe section 1 carries at its lower end a .CII

grain chute 3, and is provided with openings i inits sides, only one of which is shown in the drawing, the bottom of the section 1 being vclosed by the chute 3. In addition to the usual side and rear end walls the chute is 'provided with a transverse partition 5 which terminates short of the bottom of the chutel 3 so that grain escaping through the openings 4l can flow under said partition and down the forwardlyinelined porti-on of the chute. This partition prevents the weight of the grain which may accumulate in the upper rear portion of the chute from bearir ff upon a vertically movable gate G cunted adjacent to said partition. is connected to a bar I which is provided with vertically arranged i-shaped Specification of Letters Patent.

straddling the sides of a chute 3, andtheir outer members being'pivotally connected to bars 9, respectively, which in turn are pivotally connected to the rear of said mem- 'bers to the chute. The forward ends of the bars 9 are supported by suitable springs 10 which in turn are hung from suitable brackets 11. Also hung from the springs 10 isa hopper `12 which carries the. pipe 2, and which in turn forms a movable part of the continued grain spout. The .mill may be arranged directly below the pipe 2, or this pipe may be a short section telescoping in the regular grain pipe, depending upon the location of the mill and the various pipes. Across thefront of the chute 3 is a board 13 having thereupon a'series of magnets 14;.

As the grain passes down the chute 3 it spreads out into a comparatively wide and shallow stream, and any iron particles contained therein` will be caught by the inagnets. From the chute 3 the grain falls into the hopper 12 and shouldthe feed become too rapid thel weight of grain falling into said hopper will stretch the springs 10 thereby slightly lowering the hopper, and this in turn will draw down the bars-9 and lower the gate 6, thereby reducing the rate Aof' feed. It will be seen therefore that' the of said magnets, and means connecting said movable hopper and said gate.

2. A feed regulator comprising a chiite, a grain delivery spout having an upper section'leadingv to said chute, a vertically mov-' able hopper carrying a continuation of said grain spout, said continuation being offset with respect to the upper section, a series of magnets arranged transversely"'facross thelower end of the chute and above said hopper, a gate,U-shaped members carried by the gate and straddling the ksides of the chute, pivoted bars to which said members are pivotally connected, and common means for supporting the forward ends of the bars and the hopper.

3. A device of the kind described oomprising a chute, a'grain delivery spout adapted to discharge into the upper rear portion of the chute, a transverse partition in advance of said spout, said partition terminating short of the bottom of thechute, said chute being comparatively Wide With respect to the diameter of the spout, a vertically Inovable gate arranged in yadvance of said partition, a series of magnets arranged in advance of said gate, pivoted bars,

means connecting the gate to the bars, a hopper, coil springs secured` at their upper ends to a Xed support having their lower ends connected to. said hopper, the front ends 15 J. J. WEINANDT, C. A.
