Abstract
Sights for regulating double rifles, and shotguns firing rifled slugs, to converge projectile impacts of the two barrels. Several distinct embodiments activated by inertia or the firearm's mechanism, all providing two adjustable sight leaves, one to be aligned with the impact point of each barrel. In the preferred embodiments the upstanding sight used for aiming a first shot is exchanged at the shot for the second sight by recoil inertia harnessed in one of three ways. One embodiment is reset by cooperation with the firearm but alternated by inertia, while another inertia type is reset manually. A detachable embodiment is provided for shotguns with ventilated ribs, which is both alternated and reset by inertia. A sight activated solely by the firearm's mechanism is also provided.
Claims16
Self-alternating sights for firearms such sights comprising;
- a. An aiming means with two interchanging sight setting means, each of which is alignable with a separate point of projectile impact, at a selected distance,
- b. An alternating means which when set, automatically and instantly interchanges the said sight setting means when a shot is fired from a firearm on which said sights are mounted,
- c. A resetting means to return the alternated aiming means to its set position,
- d. A means for housing the said aiming, alternating and resetting means for attaching the said sights to said firearm.
Self-alternating rear sight means for double-barrel firearms which alignably regulate projectile impact, at a given distance, of each barrel of a double-barrel firearm, the said sight means comprising, a body means with means for being detachably installed on a rib along the said firearm's barrels' assembly, and means for hingeably mounting aiming means and for housing alternating and resetting means;
- an aiming means, being a right-angular element with an aperture at its tangent for hingeable mounting to the body means, and having slottedly adjustable sighting elements threadably attached to planes of the said right-angular element and with lug means extending from the outer surface of one said plane with a pivot means positioned on said lug means approximately 45 degrees around from the lug means' host plane in relation to the right-angular element's tangential aperture;
- and a combined alternating and resetting means, being a connecting element linked articulately with said pivot means of said lug means at one end and at its other end with a shaft element movably located in a longitudinal aperture through the body means and having between the said body means aperture and an enlargement of the shaft element where it joins said connecting element, a compression spring pushing the shaft element rearward towards the aiming means, this travel being principally limited by a rigidly fixed inertia weight element on the front end of the said shaft element ahead of the body aperture;
- and with the said self-alternating rear sight means constructed, assembled and mounted in such a way that when said double-barrel firearm is loaded a first shot may be aimed using one of the said sighting elements aligned for a point of projectile impact of one barrel, and that upon firing, recoil causes the sighting elements to be alternated for aiming a second shot and that recoil from the said second shot causes the sighting elements to be reset to their positions before the first shot.
Self-alternating rear sights, for double-barrel firearms, which alignably regulate impact of projectiles from each barrel of a double-barrel firearm at a given distance, the said sights having;
- a body means optionally a part of another sight-related structure and providing lugs for hingeably mounting aiming means, and contoured recesses for positioning springs and resting aiming means when folded away and when set for use;
- an aiming means, being two independently rotating sight leaf-mounting means (to be called the first sight means and the second sight means) on which sight leaves are alignably afixed by a fixing means;
- an alternating means, being a weighted inertia means at the outer end of the first sight means for tipping over the said first sight means under recoil, and a tripping means beneath the hingeable mounting for cooperating with the second sight means to lift it into view for aiming a second shot to be fired;
- a resetting means, being a grip means at the outer end of the first sight means which when pulled up and back through its arc of movement, lifts the second sight means, which is brought beyond vertical and rested against a resting recess in the body means, after which the first sight means is pushed forward again to the vertical position where it is located by a flat on its base bearing against a spring means;
- and said sights performing their alternating function by the weighted first sight means overcoming said spring means under the recoil inertia of a first shot from said firearm and toppling forward, and said spring means then locates the second sight means base when the second sight means is raised to the vertical position by the cooperation of said tripping means on the first sight means.
