Abstract
624,275. Machinery guards. MOULDED PRODUCTS, Ltd., WILKINSON, W. D., and HEMMINGSLEY, H. R. June 25,1947, No. 16723. [Class 80 (iv)] A valve controlling the supply of pressure fluid to the head of a hydraulic press is itself controlled by the safety guard of the machine. As shown, the guard 11, which is slidable and carries a cam surface 33, is closed and pressure fluid controlled by a valve (not shown) to an inlet port 19 can pass from the port 19 to the ram of the press through an outlet port 20, a piston 29 preventing access to an exhaust outlet 23. During operation of the press, hydraulic pressure acting on the piston 29 presses the follower 30 on the piston spindle 25 against a face 32 on the guard and resists movement of the guard to the open position. When the hydraulic pressure has been released, the guard may be slid open and the piston 29 raised by the cam 33 to close the port 20 and connect the inlet port 19 with the exhaust outlet 23.
