Description:
Abstract:

This invention has for its object to produce a simple and inexpensive grinding wheel especially adapted for face grinding, which shall comprise a flanged carrying disk, a plurality of grinding blocks of novel configuration and means for adjusting the blocks so that the blocks maybe practically used up, thereby avoiding waste and greatly reducing the cost of the operation of grinding. With these and other objects in view I have devised the novel grinding wheel and grinding blocks therefor, which I will now describe, referring to the accompanying drawings forming a part of this specification and using reference characters to indicate the several parts.

Claims:

1. A grinding wheel comprising a carrying disk having inner and outer flanges on its face, walls between said flange oblique to radial lines, grinding blocks in pairs lying between the walls, and means for forcing the blocks of each pair against contiguous walls and the outer flange to lock them in place.

2. A grinding wheel comprising a carrying disk having inner and outer flanges on its face, walls between said flanges oblique to radial lines, grinding blocks in pairs lying between the walls, a locking block between the grinding blocks of each pair and means for moving the locking blocks into locking position.

3. A grinding wheel comprising a carrying-disk having inner and outer flanges on its face, walls between said flanges oblique to radial lines, grinding blocks in pairs lying between the walls, means for adjusting the grinding blocks inward and outward and means for locking the grinding blocks in position after adjustment.

4. A grinding wheel comprising a carrying disk having inner and outer flanges on its face, walls between said flanges oblique to radial lines, grinding blocks in pairs lying between the walls, means for adjusting the grinding blocks inward and outward, a locking block between each pair of grinding blocks and means for moving the locking blocks into locking position.

5. A grinding wheel comprising a carrying disk having flanges on its face, grinding blocks provided with base plates, screws engaging the base plates to move said blocks inward or outward and means for locking said blocks after adjustment.

6. A grinding wheel comprising a carrying disk having flanges on its face, grinding blocks provided with base plates, screws engaging the base plates to move said blocks inward or outward, angular locking blocks each acting on two grinding blocks and screws engaging the locking blocks to move and retain them in locking position.

7. A grinding wheel comprising a carrying disk having inner and outer flanges on its face, said inner flange being inclined on its outer face and oblique walls between the flanges, grinding blocks, inclined locking blocks each acting on two grinding blocks, and screws held in the carrying disk and engaging the grinding blocks and the looking blocks, substantially as described, for the purpose specified.

8. A grinding wheel comprising a carrying disk having inner and outer flanges on its face and oblique walls between the flanges, grinding blocks in pairs between .the walls and adapted to project beyond the walls, leaving clearance spaces between the grinding blocks, and a locking block between the grinding blocks of each pair acting to force the grinding blocks against the walls and the outer flange.

9. A grinding wheel comprising a carrying disk having inner and outer flanges on its face and oblique walls between the flanges, grinding blocks in pairs between the walls and adapted to project beyond the walls, leaving clearance spaces between the grinding blocks, screws for moving the base grinding blocks inward and outward, locking blocks between the grinding blocks of each pair and means acting on the locking blocks to force the grinding blocks against the walls and the outer flange.

10. A grinding block whose outer end is a convex curve, whose inner end is a concave curve and whose front and read side lines are oblique to radial lines.

11. A grinding block having a metallic base provided with a threaded hole and whose inner and outer ends are respectively concave and convex curves and whose front and rear side lines are oblique to radial lines.
