Abstract

583,762. Machinery guards. ALDOUS & CAMPBELL, Ltd., and MEERING, L. H. Nov. 30, 1944, No. 23919. [Class 80 (iv)] The guards 1 of a hydraulic press are slidable in guides 2 and connected by chains 3 passing over pulleys 5 to counterweights 6 The pulleys 5 are provided with cam projections 5A adapted to engage the ends of a floating lever 7 which is pivoted on a control lever 8 of a pilot valve 10 controlling the supply of hydraulic fluid to, and the exhaust from, a servo cylinder 11 for operating the main valve G of the press. The arrangement is such that with both guards closed the valve G is actuated to operate the press ram but if either or both guards are opened, or left open, the valve G is actuated to exhaust the ram cylinder and stop the operation.
