ABSTRACT:
An explosively actuated tool for driving a fastener into a substrate is of the type in which the tool is mounted to the end of a pole-like handle to permit manipulation and actuation of the tool from a remote position wherein actuation of the tool occurs by pushing the forward end of a barrel of the tool against the substrate using the handle and then pushing on the handle which loads and then releases the firing mechanism of the tool. A lock device is incorporated to prevent “air firing” of the tool by pushing the handle without the forward end of the barrel being pressed against the substrate. The lock device has a lock member which cooperates with the firing pin or firing pin spring support of the firing mechanism to lock one or other of those components unless the lock member is released by a prior displacement caused by retraction of the barrel when its forward end is pressed against the substrate.
