UNITED STATES LEIF J. INGOLII?SBU'ID AND WILLIAM H. SO'ULE, F CONISTON, ONTARIO, CANADA .arrnnarus Application Our invention has for its object a method and means (1) for separating magnetic material from nonmagnetic material, and (2) for separating magnetic material into varix ous grades according to its magnetic properties.
The method consists of conveying material of various magnetic propertieson a surface inclined sideways to its direction of a travel and subjecting said material to magnetic attraction towards said surface so that its gravitational tendency to roll or slide ofi said surface is retarded by the increased friction due to the magnetic attraction, this retardation being proportional to the magnetic properties of the individual pieces of -the material. By varying the inclination of the surface or the strength of the magnetic field or by varying both along the direction of travel of the material, pieces of different magnetic properties are made to roll or slide off the surface at difierent points. This may be accomplished by means ofa belt mounted so as to present a gradual increasing incline magnets mounted up to the underside of said belt, means for feedlng'material onto said belt and proper receptacles to collect theseparated material.
In' the accompanying drawings, similar reference symbols refer to similar parts throughout the several views.

' 12 and lying at an angle to the same. Shafts 13 and 35 are mounted in suitable bearings on a frame of convenient form not shown on drawings.
Upon pulleys 12 16 and due to the position of the pulleys, the belt will be twisted, giving a varying inclination of the belt surface. Underneath top portion of belt 16 is mounted an electromagnet 17 which is kept magnetized by a current from a suitable source 18. A hopper 20 is attached in a suitable manner to a feeder 21, which feeds the untreated material 22 onto belt 16,-it being understood that any type of suitable feeder may be used.
the, belt until the magnetic force is nomoreable to retain the same,when it will fall in any of the other receptacles, according to its magnetic properties.
Referring to Figures 4, 5 and 6, the pulleys 12 and 15 are mounted as described for Figures 1, 2 and-3 and magnets (24, 25, etc.)
part of the belt 16. The feeding of materlal to belt 16, the
separation and collecting of the separatedmaterial and other details are similar to that described for Figures 1, 2 and '3.
Referring to Figures 7 and 8: Due to different shapes, weights and roughness of indiand 15 is mounted a belt 0 belt first and fall into the vidual pieces, it may be necessary to first classify the material to be treated according to its tendency to roll or slide off an incline belt before it is scribedfor Figures 1,2 and 3. No magnets a small inclination of the belt to slide will fall into one receptacle. Material requir ng a steeper inclination of the belt will slide into another. receptacle and so on into their fed to the magnetic separator.. This is accomplished by mounting pulleys 32 and'31 and belt 30 in a similar man- 1 nor to pulleys 12 and 15, and belt 16,. as de- "are used under belt 30. Materialrequiring 70 Under the lower edge of belt 16 is mounted 53 Lee now be separated acoortling to its magnetic prggerties. hat We claim as our invention and desire to protect by Letters Patent is In a magnetic separator, an endless travelling belt, said belt being mounted to travel at a graduallyincreasing inclination sideways to its direction of motion, magnets mounted adjacent to the underside of the belt, means for feeding the material to be separated on to the upper surface of said ass? belt, and means to gather the graded material as it falls from the belt.
An apparatus as claimed in claim 1 in which a series of magnets of different strengths are mounted beneath the belt.
In testimony of the foregoing, We have hereunto aflixecl our signatures, this 23rd day of December, A. D. 1924, at Sudbury,
Ontario.
