Abstract
A mechanism for remotely manipulating a rotary adjustable choke device on the muzzle of a shotgun barrel. Specifically, the mechanism consists of a reciprocatory operating arm positioned intermediate the choke device and the breech end of the barrel, in combination with a connection between the arm and device for converting the reciprocatory motion of the former into oscillatory motion of the latter, thereby varying the muzzle constriction and shot pattern. The arm is positioned so that it may be manually reciprocated by the shooter to selected releasable positions corresponding to the desired choke settings and while the gun is held in firing position.
Claims6
In combination, a shotgun having a barrel, a tubular member forming an extension of the muzzle of said barrel, means threadably mounted on said member and rotatable about the axis of the barrel for varying the constriction at said muzzle, an elongated arm mounted for reciprocable movement longitudinally adjacent said barrel, and means responsive to the reciprocable movement of said arm for imparting rotary movement to said threadably mounted means to thereby increase or decrease said muzzle constriction.
