Abstract: Granitic stone slabs can be split into thin rock-faced veneers by opposed tools forced into the slab from opposite sides. One tool comprises a radiused contact surface and the other a sharp edge, with a beveled surface on one side thereof.

Abstract: Spaced parallel circular tracks rotate 180 degrees on roller bearings. Matching openings through one edge of each track serve to admit a stone or heavy object into a receiving slot. Parallel roller conveyors line the top and bottom faces of the slot. A pivoting swing with a platform across the inside of the slot transfers the stone from one face to the other automatically when the apparatus is rotated. The center of gravity of the loaded turning apparatus coincides with the center of rotation thereby requiring very little turning power. A manual handle or motor drive shaft rotates the gear train to turn the apparatus. Transverse rollers permit entry and exit of the stone at opposite points on the circular track. Longitudinal rollers permit entry and exit of the stone from the same or opposite sides of the apparatus.
