Abstract
653,137. Machinery guards. PRESS GUARDS, Ltd., and EVANS, F. A. Aug. 26, 1948, No. 22490. [Class 80(iv)] A vertically movable guard I of a power press is adapted to close from the raised position shown by gravity and to be raised by pressure fluid admitted below apiston secured to the guard of a cylinder n through a manually controlled valve r. A switch t in the starting circuit of the machine is adapted to be operated to close by a projection on' the guard only when the guard is in its fully closed position and the guard is held in the closed position, whilst the machine is operating, by air pressure used for actuating the clutch of the machine also acting above the piston of cylinder n through a pipe s. Obstruction of the guard in its closing movement results in a pivotal movement of an auxiliary part u for stop pawls v thereon to engage stationary racks w to arrest further movement. A stationary bottom guard portion x may also be provided and may be adjustable. In a modified arrangement the guard co-operates with a valve controlling the supply of pressure fluid to actuate the machine clutch so that the valve is opened to engage the clutch as the guard reaches its fully closed position.
