Abstract
A machine safety guard for stopping a machine during any phase of operation to prevent injury to workers in which a guard lever is disposed between the worker and the hazardous area of the machine and is connected on one end to a pivot shaft. An activating arm extends from the shaft and has a post for operating a microswitch which is connected to the emergency circuit of the machine. When the guard lever is touched the lever pivots on the shaft, thereby lowering the post from the microswitch, causing the emergency circuit to stop the machine. A counterweight is used to control the sensitivity of the guard lever.
