ABSTRACT:
An industrial gun, of the type having a transverse sliding breechblock, has a firing mechanism which automatically cocks and then releases a hammer as the breechblock closes. A sear is pivoted in the yoke or receiver of the gun in a position to engage and cock a hammer carried by the breechblock as the breechblock is moved from an open to a closed position. A cam surface on the sear bears against a cooperating cam surface on the hammer to release the hammer from the sear as the breechblock reaches the fully-closed position, in which a firing pin carried by the breechblock attains correct alignment with a shell in the gun chamber. A set screw provides an adjustable cam surface on the hammer to allow the correlation of the timing of the hammer release with the breechblock movement to be readjusted precisely as the parts wear with use.
