ABSTRACT:
A limit switch gauge positioner for a machine ram supporting a forming tool or the like. The ram, supported for reciprocal movement relative to a head, has a lineal distance gauging rod thereon formed with a plurality of longitudinally graduated reference indents. The rod has a body member slidable thereon including a detent coupling plunger adapted for engaging a selected one of the indents allowing an operator to initially locate the body member relative to the ram. A micrometer is supported on the body member with its spindle being settable at graduations along the spindle axis parallel to the path of travel of the ram. The head supports a housing including a microswitch with its actuator aligned on the spindle axis. An operating member is pivoted on the housing intermediate the switch actuator and spindle and gravitationally biases an arm section into arresting contact with the actuator in its extended switch closed position. The spindle engages and pivots the operating member, responsive to travel of the ram to initially depress the actuator de-energizing the ram drive source. The operating member has a gauged stop finger section which, upon subsequent ram travel provides positive engagement with the housing resulting in the ram being accurately located relative to a known pre-set micrometer graduation.
