ABSTRACT:
A safety guard structure including a guard member adapted to be interposed between a mechanism such as a punch press and the operator thereof to protect the operator from injury. In one form of the invention the guiding frame for guiding the guard member between its upper and lower positions is swingably connected to the mechanism to be guarded to permit the entire guiding frame to be swung upwardly so as to present no interference when it is desired to modify the mechanism or to change the dies thereof. In another form of the invention the guide structure for the guard member is entirely positioned above the area to be protected so as to present no interference when it is necessary for operators to work around the machine. An interlocking device is provided to prevent operation of the mechanism except when the guard member and its guide structure are in proper operating position.
