Abstract

The collimator of the present invention is intended to be carried within a telescopic gunsight. The collimator of this invention comprises an eyepiece reticle suitably disposed from the eyepiece of the gunsight, a forward reticle disposed distally forwardly of the reticle erector of the gunsight and means for horizontally and vertically adjusting the relationship of the eyepiece reticle and the forward reticle. The horizontal and vertical adjusting means include a horizontal set-screw-type adjusting means carrying the eyepiece reticle, and a vertical adjusting means carrying the forward reticle. A further embodiment of this invention includes an eyepiece reticle etched onto the eyepiece of a gunsight and a forward reticle having both horizontal and vertical adjusting means.

Claims

1. In combination with a telescopic gunsight including an objective lens, a reticle-erector, eyepiece lens, and a collimator, as alignment device comprising an eyepiece reticle assembly disposed from said eyepiece of said gunsight, a forward reticle assembly disposed distally from the forwardmost terminal end of said reticle-erector of said gunsight, and means horizontally and vertically adjusting the relationship of said eyepiece reticle and said forward reticle.

2. The apparatus of claim 1 wherein said means horizontally and vertically adjusting said eyepiece reticle and said forward reticle include a horizontal adjusting means carrying said eyepiece reticle, said eyepiece reticle comprising a socket disposed in the tube of said gunsight and being juxtapositioned to a horizontal cross hair of said gunsight, said socket having a boring including threads on its outer portion and smooth polygonal walls on its portion closest to the central axis of said tube, said boring being disposed rectilinearly in said socket, an adjusting screw operable to threadably engage said boring threads, a stem having said reticle fastened at one of its terminal ends and having means at its end opposite operable to engage said polygonal boring, and urging means carried on said stem operable to outwardly urge said eyepiece reticle with respect to said central axis of said tube;

and a vertical adjusting means carrying said forward reticle including a socket, stem, and urging means similar to said eyepiece reticle socket, said stem and said urging means being disposed parallelly to a vertical cross hair of said gunsight.

3. The apparatus of claim 1 wherein said means for horizontally and vertically adjusting said eyepiece reticle and said forward reticle include an eyepiece reticle etched onto said eyepiece of said gunsight and a forward reticle having both horizontal and vertical adjusting means.
