APPLYING ABRASIVE MATERIALS.
SPECIFICATION forming part of Letters Patent No. 588,441, dated August 17, 1897.
Application filed September 30, 1895-. Serial No. 564,075. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAirL. KANN, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Applying Abrasive Materials, of which the following is a full, clear, and exact description. f
My invention relates to the movable tables or disks upon which is thrown a comminu'ted metallic abrasive employed for grinding or polishing glass, stone, or other material which is applied to the abradent-covered surface; and it consists in providing magnets for holding' the abrasive in place upon the disk or table while the article to be ground or pol ;shed is applied to the abradent-coveredsurace.
In thedrawings, in which the figure is a diagrammatic view illustrating one form of myimproved apparatus, 2 is a rotatory grinding-table secured to the shaft 3 and having fastened to its lower face electromagnets 4 and 5, which create a magnetic field at the upper face of the plate, the plate becoming magnetic and holding the abrasive particles in place thereon until they are worn out, or as long as desired. The current may be led to the magnets by any suit-able means,
the device shown consisting of a circular plate 6, secured to and revoluble with the shaft, this plate carrying two insulated metallic rings 7 and 8, the ring 7 being connected to the magnet 4, while a return-wire leads from the magnet 5 to the ring 8. These rings are embedded in insulating material 9 and with their lower faces contact the springbrushes 10 and 11, secured to concentric insulated rings 12 and 13. The rings 12 and 13 are stationary and embedded in insulating material 14, and to them lead the positive and negative wires from a dynamo 15 or other source of electricity.
The action is apparent. The table being rotated and the current switched on it flows up through one set of rings and brushes to one magnet, thence through the table to the other, and thence back through the other set of rings and brushes. v
When the metallic abrasive material is thrown upon the table, it is held thereon by the force of magnetism and its full abrasive power exhausted.
The advantages of my invention result from the small amount of abrasive necessary and the reduction in the cost consequent thereon. The only refuse flowing away consists in the particles of the stone, glass, or other material operated upon, and the amount of labor in storing and feeding the abrasive is greatly reduced.
cured to and rotatory with the table, which constitutes their pole-piece, substantially as described.
In testimony whereof I have hereunto set my hand.
WILLIAM KANN.
