ABSTRACT:
The invention comprise a stone shaper device for shaping neck pendants into various desired shapes and sizes. The device has a main frame and a frame slidable on the main frame and a cam shaft having cams of various sizes and shapes on the cam shaft, with a pair of arms pivotally mounted at their one ends to the sliding plate and the cam shaft rotatably mounted to the other ends of the arms, and means to rotate the cam shaft, an adjustable roller is adjustable into a position in front of a selected one of the cams. A stone for grinding into a selected shape is mounted perpendicular to one end of a grinding shaft and the cam shaft has a chuck at one end to receive and lock the grinding shaft therein. Spring means are provided to urge the cam shaft toward the roller so that the selected one of the cams may engage the roller and so that when the selected one cam is rotated by the cam shaft it will push the cam shaft away and allow it to move toward the roller depending upon the variations in the selected cam so that a grinding wheel adjacent the stone for grinding will guide the stone into the shape of the selected one cam.
