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.
Claims17
A safety tool for use in overcoming the effects of inertia on a locking device disposed on a machine tool to lock and unlock a longitudinally moveable machine element, wherein the locking device includes a bolt having a bolt head at one end thereof, and a radially outwardly extending lever movable between a locking and unlocking position of said locking device, said safety tool comprising in combination:
- a cap, said cap being adapted to and fit upon the knob of the locking device, said cap having a disc portion, a side wall depending from said disc, and an opening defined by said disc and said side wail for encircling the lever of the locking device;
- means defining a counterweight, said counterweight being connected to said cap in radial opposition to said opening in said side wall, said counterweight being positioned to overcome the effective mass of said lever so as to urge said lever toward an unlocked position.
