PATENT OFFICE.
tlNlTED STATES CHARLES E. BLIZARD, OF WEST HAVEN, CONNECTICUT, ASSIGNOR TO WINCHESTER REPEATING ARMS 00., OF NEW HAVEN, CONNECTICUT, A CORPORATION.
SIGHT FOR FIREARMS.
Application filed April 7, 1925. Serial No. 21,303.
Fi 1 is a plan view, on an enlarged scale, of my improved sight, shown as installed upon a gun-barrel which is broken away.
Fi 2 is a corresponding side view thereof.
Fig. 3 is a view thereof, partly in central, longitudinal section, on the line 38 of Fig. 1, the fine-adjustment screw and the elevator being shown in side elevation.
Fig. 4 is a detached, plan view of the sight, with the elevator removed.
F 5 is a corresponding view of the elevator.
My invention relates to an improved siglnfor firearms, the object being to provide a simple, convenient and reliable sight constructed with particular reference to provision for the line adjustments required for Zeroing.
With these ends in view, my invention consists in a sight for firearms characterized by provision for the fine adjustments required for zeroing, in addition tothe coarse adjust ments required for various ranges.
My invention further consists in certain details of construction and combinations of parts as will be hereinafter described and particularly pointed out in the claims.
In carrying out my invention, as herein shown, for the fine adjustments of the sight required for Zeroing, I employ a headless screw 10, installed in a substantially vertical position in a threaded hole 11 located in the center of the sight-leaf 12, upturned from he rear end of the flat sight-spring 13, which is formed at its rear end with a longitudinal slot 1st, and upon the lower face of its forward end with a transversely-arranged dovetail 15 adapted to enter a transverse dovetail 16 in the gun-barrel. 17, whereby the sight is secured in place.
The slot 14 receives an elevator 18, the upper edge of which is formed with notches 19 arranged in a generally rising sequence, and receiving the pointed. lower end of the fine adjustment screw 10, these notches being carefully calculated to provide the successive increases in height required for successive increases in range. The lower edge of the elevator 18, which constitutes the coarse adjustment means of the sight, rides upon the top of the gun-barrel, while at its forward end it is provided with a cross-scored thumbpiece 20, by means of which the elevator may be moved back and forth under the screw 10 by using the fingers to lift the sight-leaf 12 against the tension of the sight-spring 13.
In the use of my improvement, the leaf 12 is lifted against the tension of the spring 13, and the elevator moved rearwardly or forwardly to bring under the pointed end of the screw 10 the particular notch representing the approximately correct adjustment of the sight for a given range. The arm is now tested at such range and the line-adjustment screw used to correct minor errors in the setting, the method above described being known as zeroing the sights of the arm.
By my improvement, I am thus enabled to place in the hands of the user of the arm convenient and accurate means of adjusting the sight to his particular vision, since it is well known that in order to secure the best results with any firearm, the sight thereof must he minutely adjusted to the users individual equation of vision, and this requirement is completely met by the fine-adjustment provision of my improvement.
I claim:
1. A sight for firearms having a sightspring, a sight-leaf upstanding therefrom, means co-acting directly with the said leaf for the coarse adjustment of the same, and means carried by the said leaf and co-acting directly with the said coarse-adjustment means for the tine adjustn'ient of the sight.
2. A sight for firearms having a sightspring, a sight-leaf upstanding therefrom, means coacting directly with the said leaf for the coarse adjustment of the same, and a screw mounted in the said leaf and hearing tern'iinally against the said coarse-adjustment means for producing minute alterations in the relative positions of the said leaf and coalee-adjustment means.
3. A sight. for firearms having a sightspring, a sight-leaf i'lpstanding from the rearward end thereof, a slii'ling wedge po itioned below the said sight-spring in contact therewith for the coarse adjustment of the said leaf, and a zeroing screw i'uounted in the said leaf and bearing terminally upon the upper portion of the said wedge for producing minute alterations in the relative positions of the said leaf and wedge.
In testimony whereof, I have signed this specification.
CHARLES E. BLIZARD.
