Abstract
In combination with the barrel of a shotgun, a sighting rib extending along said barrel thereabove, and pivoted to said barrel at its rearward end on a horizontal transverse axis, and one or more short links extending angularly between the barrel and rib at their forward ends, the links being both pivoted and longitudinally slidable relative to the rib and barrel to permit changing of their angularity adjust of the angularity of the rib to the barrel, and mechanism for securing one end of each link against pivotal and sliding movement, whereby the angularity of the rib to the barrel may be fixed as desired, while leaving the opposite end of each link freely slidable to permit unequal longitudinal thermal expansion of the rib and barrel.
Claims7
In a shotgun:
- a. an elongated barrel,
- b. an elongated sight rib assembly extending generally coextensively with and approximately parallel to said barrel, in spaced apart relation thereabove,
- c. means connecting the rearward end of said assembly to said barrel for pivotal movement on a horizontal transverse axis, whereby said assembly may be tilted in a vertical plane relative to said barrel,
- d. connecting means joining the forward end of said assembly to said barrel adjacent the muzzle end of the latter, and adjustable to vary the vertical angle of said assembly relative to said barrel, and
- e. securing means operable to secure said connecting means against adjustment, whereby to secure said assembly at any desired degree of vertical angularity relative to the barrel, said connecting means including a connecting member joining said assembly and said barrel, and being slidably movable relative to said barrel in a direction longitudinal to said barrel, even when said connecting means is secured against adjustment by said securing means.
