Abstract
Abstract A gun sight for small firearms having applicability to short and medium range, quick-firing situations and for night-firing has been invented. The gun sight or aiming device comprises a pair of U-shaped sights each having a horizontal opening of substantial width. The horizontal opening of the front sight can be sufficiently wide to permit sighting of a target therethrough under conditions of substantial darkness. The U-shaped rear sight has a horizontal opening sufficiently wide so that at least a portion of the face of the front side on each side of the Ushaped opening can be viewed by an operator aiming the weapon. Also, the front sight may contain on its rear face a pair of rectangular, light-colored patches having sides coextensive with the upper edge of the sight and the vertical interior edge of the sight; each patch being located on opposite sides of the U-shaped opening.

Claim 1
Independent Claim
117 words
A gun sight for small arms comprising: a. a U-shaped front sight having upstanding, transversely spaced right and left vertical-interior-walled posts defining therebetween a U-shaped sighting opening of sufficient horizontal width to permit sighting of a target therethrough; and b. a U-shaped rear sight spaced rearwardly of said front sight and having upstanding, transversely spaced right and left vertical-interior-walled posts defining therebetween a U-shaped sighting opening of sufficient horizontal width, relative to the distance between said sights and sighting eye placement relative to the latter, for at least a portion of the right and left posts of the front sight adjacent to the U-shaped sighting opening to be visible when viewed by an operator aiming the firearm.
Claim 2
Dependent Claim
117 words
A gun sight for small arms comprising: a. a U-shaped front sight having upstanding, transversely spaced right and left vertical-interior-walled posts defining therebetween a U-shaped sighting opening of sufficient horizontal width to permit sighting of a target therethrough; and b. a U-shaped rear sight spaced rearwardly of said front sight and having upstanding, transversely spaced right and left vertical-interior-walled posts defining therebetween a U-shaped sighting opening of sufficient horizontal width, relative to the distance between said sights and sighting eye placement relative to the latter, for at least a portion of the right and left posts of the front sight adjacent to the U-shaped sighting opening to be visible when viewed by an operator aiming the firearm.
Claim 3
Dependent Claim

Claim 4
Dependent Claim

The gun sight of claim 1 wherein the width of the opening of the U-shaped rear sight is dimensioned to be sufficiently large that an object can be viewed therethrough under conditions of substantial darkness without the vertical sides of the opening appearing to fuse together and obscure the object.
Claim 5
Dependent Claim
173 words
A gun sight for small firearms comprising: a. a front sight provided with mutually laterally spaced posts having respective rear faces and a U-shaped sighting opening of sufficient horizontal width between said posts to permit sighting of a target therethrough, a pair of light colored patches disposed on said post rear faces proximate said sighting opening at upper regions of said posts, each patch being of the same shape and having substantially the same dimensions, and both patches being horizontally aligned; and b. a rear sight spaced from said front sight, positioned relative to intended sighting eye placement, and having a U-shaped sighting opening of sufficient horizontal width for at least a portion of said rear faces of said right and left posts of the front sight adjacent to the said U-shaped sighting opening and the said pair of patches on said rear faces to be visible when viewed by an operator aiming the firearm, said rear sight being dimensioned to mask out, relative to the viewer, the remainder of said front sight.
