Abstract
A machine for finishing the surface of a lens mounted on one side of a lens block having receiving depressions in its other side, the machine having a cylindrical tube mounted for rotary and reciprocal motion on a fixed shaft, an optical tool holder affixed to one end of the cylindrical tube and adapted to receive an optical lap thereon, an arm having pins extending therefrom to engage the pin recesses in a lens block having a lens mounting thereon for holding the lens in contact with the optical lap, a coupling block affixed to the cylindrical tube adjacent the other end thereof and having a spherical plane bearing therein, an outer cylindrical drive member having an eccentric longitudinal opening therethrough, an inner cylindrical drive member also having an eccentric cylindrical opening therethrough, the inner cylindrical drive member being rotatably received in the opening through the outer cylindrical member, the cylindrical drive members being independently related, a shaft extending through the longitudinal opening in the second cylindrical drive member having indexing means so that the position of the shaft relative to the second drive member may be fixed, but when fixed, the shaft rotates with the second cylindrical drive member and an eccentric connector at one end of the shaft having a secondary drive shaft engaging the spherical drive bearing so that as the outer and inner cylindrical drive shafts are rotated, rotational and reciprocal motion is applied to the cylindrical tube.
