To all 'whom 'it may concern: p

Be it known that I, FRANK'J. PHILLIPS, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electromagnetic Separatore; and I do hereby declare that the fol owing description of my invention, taken in connection with the accompanyin sheet of drawings, forms a full, clear, an exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to im rovements in electromagnetic separators; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

The object of this invention is the production of an eiiicient, serviceable, convenient, and comparatively inex ensive a paratus for separating ferrous substances rom non-.ferrous met-als, and it is especially designed for removing iron and steel from copper, brass, bronze, aluminum and similar turnings.

It is a Well-known fact that non-ferrous turnings such as are produced in machinesho s brass-finishing shops, and other estab ishments, contain more or less ferrous substances resulting from the wearA and breakage of steel too1s,- while operating on non-ferrous metals and also from ferrous articles being operated upon in the same machines in which non-ferrous goods are being produced. These mixed turnings, as they are commercially termed, command generali a considerably lower price per pound t an those turnings from which the ferrous parts have been removed. By the employment of my electro-magnetic separator, I am enabled to remove from the mixed turnings all the ferrous matter at a trilling cost, so that the cleaned turnings will command the highest market price.

In the drawings already mentioned, which serve to illustrate this invention more fully, Figure 1 is an elevation of my improved electro-magnetic separator. Fig. 2 is a similar view of the same, the a paratus being turned at an an le of 90 egrees to that shown in Fi 1. i 3 is a plan, and Fig. 4 is a sectionaview of a portion of the device, on line w w of Fig. 2.

' movable Like Iarts are designated b correspondmg sym ols and characters o reference in al the res This e ectro-magnetic separator comprises an iron basket, A, which may be magnetized' by passing an electric current through a coil located between the members of said basket, and which will demagnetize as soon as the electric current is interru ted. This basket includesl two, forked mem ers 12, 13, which, by means of screws 14, are connected to an o long iron core 15, Fi 4, one at each end. This core is surrounde by an insulation 16, and upon this insulator 1s wound the wire constitutin the coil 17, which winding is surrounds by an insulation 18, and the latter covered by a metallic jacket 19, to protect the coil from injury, said jacket being clampedto the coil by screws 20, and retherefrom by removing 'said screws 20.

To the forked members 12, 13, there is secured a yoke B, by means of screws 21, which yoke terminates in a socket 22, which is internally screw-threaded to engage the similarly screw-threaded end of a tube C, which serves as a manipulating rod for this apparatus and to contain the electroconductor that leads to the coil. On this tube C there is a swivel D, by which, and a rope 23, the apparatus may be suspended from any overhead object to relieve the o p-l erator who 'actuates the same, from its weight.

On the upper end of the tube C there is located a switch-socket E, to which an electroconductor F, is connected, while a continuation F, of this conductor F leads from the switch-socket E to the winding 17 of the coil, and from the same, in the usual manner, the circuit being controlled by the switch-button 24. The cord F is of sufficient length to con- Ilect to a source of electricity by the plug G,

Near the upper end of the tube C there is located a guard H, of any desired design adapted to protect the switch socket at the upper end of the tube C when the apparatus is placed against the wall or other object, not shown.

In operation, this device is ushed into a heap of turnings and an electric current sent to the spool or coil by turning the button 24. This w1l1 cause the magnetization of the forked members 12, 13, so that any ferrous matter with which the tines 25 come in contact will adhere thereto, and which will drop from? said tines as soon as the ap aratus '1s withdrawn from the turnings an the current turned off. The tines 25 are inwardly bent at their lower ends and form, as it were, `a basket which will contain quite a bulk of the ferrous substance, it being a fact that with an apparatus as described I have removed from a heap of brass turnings approximately 50 pounds of iron turnings at one picking. o

The entire apparatus is comparatlvely slmple, not liable to get out of order, and very efficient in its actlon.

I am aware that changes in the details of construction of this apparatus may be made without departing from the scope of my in vention.

Havinof thus fully described this invention, I cliim as new and desire to secure by Letters Patent of the United Statesl. An improved electro-magnetic separator, comprisln in combination, two members each of w ich is provided with a series of tines, said members being spaced in parallel relation, the said tines belng inwardly bent and approaching one another, an electric coil interposed between said tined members, said electric coil havin an oblong core with which said tined mem rs are in conductive contact and to which said tined members are removably secured, a box-shaped yoke secured to said tined members, said yoke having an internally screw-threaded boss, a tube in screw-threaded enga ement with said boss at one end, an electrlc switch at the other end of said tube, an electroconductor connected to said switch, a further electroconductor connected to said switch and passing through said tube to saidcoil, a swivel on said tube, and an annular rim at the up er end of said tube, said coil being surroun ed by a jacket having its ends connected by a fastening located in said yoke.

2. -An improved electro-magnetic separator, comprisin in combination, two members each of w ich is provided with a series of tines, said members being spaced in arallel relation, said tines being inwardly nt and approaching one another an electric coil interposed between said tined members, said electric coil havin an oblong core to the ends of which sai tined members are removably secured and with which they are in conductive cont-act, a box-shaped yoke secured to said tined members, said yoke having an internally screw-threaded upwardly projecting boss, a tube in screw-threaded engagement with said boss at one end, an electric switch at the other end of said tube, au electroconductor connected to said switch, a further electroconductor connected to said switch and passing through said tube to said coil, said tube bem of suiicient length to permit its being use as a handle to push the apparatus over the ground, as set forth.

In testimony that I claim the foregoing as my invention, I have hereunto set my hand in the presence of two subscribing witnesses.

FRANK J. PHILLIPS.
