JOHN G. SEKINGER, oP oItnoIrY, PENNSYLVANIA, ASSIGNOR '10 THEPITTSBURGI-I PLATE GLASS COMPANY, or PITTSBURGH, PENNSYLVANIA, A CORPORATION OF flow of material from the PENNSYLVANIA.
Application fi1ed Ju1y 21,-'1915, Serial No. 41,029. Renewed August 27,
To all whom it may concern:
Be it known that I, JOHN YSEKINGER, a citizen of the United States, residing at Ford City, in the county of Armstrong and State of Pennsylvania, have invented certain new and useful Improvements in Magnetic Separators, of which the following is a specification.
The invention relates to magnetic separators, the particular embodiment illustrated herein being designed for use in removing magnetic particles, such as iron, steel, iron rust, and the like from the batch employed in the manufacture of glass. The primary objects of the invention are the provision of a cheap, simple construction which will effectively separate from the batch the magnetic materials contained therein; the provision of a separator which will accomplish the function above stated without causing any unmixing of the batch; and the provision of a cheap, simple construction and compact form. Certain embodiments of the invention are illustrated in the accompanying drawings wherein- Figure l is a vertical section through the apparatus embodying my invention, Fig. 2 is a plan view of that part of the apparatus of Fig. 1 below the discharge hopper, Fig. 3 is a section on the line III-III of Fig. 1, Fig. 1 is a diagrammatic side elevation View of a modification, and Fig. 5 is a diagrammatic side elevation of still another modification.
Referring to Figs. 1, 2 and 3; 1 is the batch hopper containing the material from which it is desired to remove magnetic particles; 2 is a valve for controlling the hopper; 3 and 1 are pole pieces having shanks 5 and 6 carrying the windings 7 and 8; 9 is a collar carrying the shanks 5 and 6 and constituting the means to which suspending means for supportingthe separator may be attached; and 10 is a bucket or conveyer into which the material passing the separator is discharged.
The pole pieces 3 and 4 have their end faces 11 and 12 inclined as indicated in Fig. 1, the lower portions of such faces approaching each other to form a narrow slot 13. The outlet 14 of the hopper comprises an elongated slot of relatively small diameter spaced a considerable distance above the Specification of Letters Patent.

pole pieces. The valve 2 is of tapered elongatedform as will be seen by reference to Fig. 3 in connection with Fig. 1 and is provided with a shank 15 by means of which the valve is raised and lowered. The shanks of the pole pieces are securely attached to the horizontal collar 9 preferably of cast iron, and it is by means of this collar that the separator is suspended by the eyes 9 and cables 9 at any desired elevation with respect to the hopper 1.
In operation, after the receiving bucket 10 has been placed in position, the valve :3 is raised and the material allowed to tie" through the spout 141. The resistance of air to the downward flow of material cause;
strike the inclined faces 11 and 12 thus .Ql ing the magnetic forces an opportunity t1; act upon any magnetic particles contained in the batch. These magnetic particles are worked downwardly along the faces 11 and 12 by the stream of batch and finally reach a position upon the lower horizontal faces 16' and 17 of the pole pieces. When the bucket 10 is filled the valve 2 is closed and the bucket removed. The magnetic particles adhering to the surfaces 16 and 17 are then easily removed by breaking the current through the windings 7 and 8.
Fig. 4: illustrates a modified form of apparatus wherein the hopper 18 discharges between the pole pieces 19 and 20 having the inclination of their front faces 21 and 22 the reverse of that shown in Fig. 1. The operation is substantially the same as that heretofore described except that a portion of the magnetic material collected upon the faces 21 and 22 remains upon such faces instead of all being carried to the horizontal faces 23 and 24 as is the case in the construction of Fig. 1.
Fig. 5 illustrates another modification in which the opposing faces of the pole pieces are inclined as indicated at 26 and 27, the material from the hopper 28 falling upon the inclined faces 26 corresponding to the faces 11 and 12 in the. construction of Fig. 1. The magnetic articles collect upon the inclined faces 2 and horizontal faces 28. Aside from the pole pieces, the constructions in Figs. 1 and 5 follow that of Fig. 1.
What I claim is:
1. In combination, a pair of alined sub stantially horizontal pole, pieces spaced, apart and having inclined opposmg end faces forming a tapering passageway and substantially horizontal botton iaces 1neet-. g he ncl ned: a e an tetanus. a u e angles therewith, windings for energizing the pole pieces, and means for supplying material into said passageway and upon the inclined pposing faces,
2. In combination, a pair of alined substantially horizontal pole pieces spaced apart and having inclined oppqsing end Copies of this patent may be obtained for s-2s ri m iasa taper- 1 p ag y, and
having substantially horizontal bottom faces supported free to receive magnetic particles andwvithsuclnfaces accessible from beneath, windings fen; energizing the pole pieces, and a passage for supplyingmaterial tosaidpassageway, said passage having itslower end terminating at a substantial distancenabeve the upper edges of the inclined faces to permit the material tospread before it reaches suchfaces.
