Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
187 words
In a double-barrel gun having a pair of independently and selectively actuated striker mechansims each having a striker associated with a respective one of the barrels, each striker associated with a respective one of the barrels, each striker mechanism including a release element assessable from the underside of the gun and arranged when released to actuate the associated striker, and a single trigger mechanism for alternately actuating said release elements by being movable laterally between the two elements for individually and selectively actuating same, comprising the improvement wherein: said trigger mechanism includes a finger member adapted to be engaged by the finger of a marksman and means mounting said finger member on said gun for movement laterally thereof between first and second operative positions permitting selective and independent actuation of said strikers, said finger member also being positionable in an inoperative position spaced from said first and second positions, said finger member being incapable of activating said release elements when in said inoperative position; and releasable lock means mounted on said gun and coacting with said trigger mechanism for locking said finger member in said inoperative position.
Claim 2
Dependent Claim
187 words
In a double-barrel gun having a pair of independently and selectively actuated striker mechansims each having a striker associated with a respective one of the barrels, each striker associated with a respective one of the barrels, each striker mechanism including a release element assessable from the underside of the gun and arranged when released to actuate the associated striker, and a single trigger mechanism for alternately actuating said release elements by being movable laterally between the two elements for individually and selectively actuating same, comprising the improvement wherein: said trigger mechanism includes a finger member adapted to be engaged by the finger of a marksman and means mounting said finger member on said gun for movement laterally thereof between first and second operative positions permitting selective and independent actuation of said strikers, said finger member also being positionable in an inoperative position spaced from said first and second positions, said finger member being incapable of activating said release elements when in said inoperative position; and releasable lock means mounted on said gun and coacting with said trigger mechanism for locking said finger member in said inoperative position.
Claim 3
Dependent Claim
37 words
A gun according to claim 1, wherein said lock means includes a key-operated lock device mounted on said gun and coacting with said trigger mechanism for permitting said finger member to be locked in said inoperative position.
Claim 4
Dependent Claim
56 words
A gun according to claim 2, wherein said inoperative position is located substantially centrally between said first and second operative positions, and said release elements being laterally spaced a sufficient distance so that activation of said finger member when in said inoperative position results in an impact portion thereof not engaging either of said release elements.
Claim 5
Dependent Claim
60 words
A gun according to claim 2, wherein the locking device comprises a casing fixedly mounted on the gun and a key-operated locking cylinder rotatably journalled in said casing and movable between a released and a locked position, said locking cylinder when in said locked position coacting with said trigger mechanism for fixedly holding said finger member in said inoperative position.
Claim 6
Dependent Claim
71 words
A gun according to claim 1, wherein said trigger mechanism includes a holder mounted on said gun for swinging movement about a substantially vertical axis, said finger member being pivotally mounted on said holder for swinging movement about a substantially horizontal axis, whereby said holder is swingably moveable between said first and second operative positions, and said lock means coacting with said holder for selectively fixing same in said inoperative position.
Claim 7
Dependent Claim
56 words
A gun according to claim 5, wherein said lock means comprises a key-operated locking device having a key-operated locking member rotatably supported on said gun and movable between a released position and a locked position, said rotatable locking member when in said locked position coacting with said holder for fixedly maintaining same in said inoperative position.
Claim 8
Dependent Claim
20 words
A gun according to claim 6, wherein said inoperative position is located centrally bEtween said first and second operative positions.
Claim 9
Dependent Claim
34 words
A gun according to claim 7, wherein said locking device includes a casing fixedly secured to said gun and extending transversely of said gun, said rotatable locking member being rotatably journalled in said casing.
