Abstract: A safety guard apparatus for a power press prevents the ram of the press from descending until the safety guard is in position to protect the operator. On presses which are equipped with part revolution clutches, the safety guard apparatus causes the ram to stop if the safety guard sensor is raised during operation. The safety guard is reciprocably mounted in a frame attached to the power press, and a sensing member is movably mounted on the safety guard. The bottom edge of the sensing member extends below the safety guard, and upward movement of the sensing member moves a switch-contacting rod out of engagement with a normally closed switch which is held open by the rod. The safety guard is raised and lowered by a power cylinder, and when the sensing member is raised and the normally closed switch closes, the power cylinder raises the safety guard.
