ABSTRACT:
A safety device, for a powder-actuated tool, which prevents the tool from discharging as the result of accidental impact or dropping. A moveable blocking member retains the hammer in the cocked position, despite disengagement of the sear, until displaced to an inoperative position by manipulation of the trigger.
