Abstract
A pattern simulator is for use with a grinding machine, especially a machine for grinding eyeglass frames, the machine comprising a grinding wheel support shaft, a pattern support shaft coplanar with the grinding wheel support shaft and a box member carrying the pattern support shaft and adapted to pivot relative to the grinding wheel support shaft. A bearing key in the grinding machine is adapted to support a pattern mounted on the pattern support shaft, an end of which overlies the bearing key. The pattern simulator is adapted to conjugate the distance between the grinding wheel support shaft and the pattern support shaft with the angle of rotation of the pattern support shaft on itself relative to a reference. The pattern simulator constitutes a self-contained mechanical entity and comprises a mounting piece adapted to be fitted to the pattern support shaft of the grinding machine and keyed to it to rotate with it. It further comprises a frame rotatably mounted on the mounting piece and a skid carried by the frame adapted to bear on the bearing key of the grinding machine and movable on the frame in translation substantially perpendicularly to an axis of the mounting piece.
