ABSTRACT:
The present invention relates to a safety tool having particular, although not exclusive, use in conjunction with machine tools in which a locking device is employed to lock and unlock a movable machine element and wherein a counterweight is employed in conjunction with a cap that fits over the locking device to overcome the inertial focus on the locking device which tends to urge the locking device toward a locked position.
