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. The pattern simulator finally comprises angulation means adapted to control the angular orientation of the mounting piece about its axis.
Pattern simulator for use with a grinding machine comprising a grinding wheel support shaft, a pattern support shaft coplanar with the grinding wheel support shaft, a box member carrying said pattern support shaft and mounted for pivotal movement relative to said grinding wheel support shaft, a bearing key for supporting a pattern mounted on said pattern support shaft, an end of said pattern support shaft overlying said bearing key, said pattern simulator defining means for conjugating the distance between said grinding wheel support shaft and said pattern support shaft with the angle of rotation of said pattern support shaft on itself relative to a reference, said pattern simulator constituting a self-contained mechanical entity and comprising mounting piece carried by said frame for bearing engagement with said bearing key of the grinding machine and movable on said frame in translation substantially perpendicularly to an axis of said mounting piece, and angulation means for controlling the angular orientation of said mounting piece about its axis.
