ABSTRACT:
Relates to gauging mechanism for machine tools such as high production grinding machines and the like, and more particularly to a quadrilateral arrangement of arms for guiding movement of a gauge in opposite directions along two angularly related paths of travel and at different rates of speed. A power source for accomplishing such movements of the gauge is a single prime mover which reciprocatingly drives a carriage along a fixed track. In the illustrated embodiment of the invention, the single prime mover is a rotary electric motor which operates through coupling means to drive the carriage along the track with a simple harmonic motion timed to apply the desired fast and slow rates of speed to the gauge in accordance with the positions of the gauge in its paths of travel. Electrical control means is incorporated into the mechanism for automatically stopping the motor's operation at each end of the carriage stroke in order to stop the travel of the gauge at an at-rest position remote from the workpiece in a machine tool and at a position hooked-on to the workpiece in measuring engagement therewith.
