1 claim. l
This invention is an improved gunsight; and especially a gunsight offering great accuracy of aim when properly employed for the purpose of directing a bullet or other projectile at its mark.
An important object of this invention is to provide a gunsight of simple construction and inexpensive to produce and mount; and so designed as to create superior optical conditions of which the shooter can take full advantage and win for himself a higher rating as a marksman, either on the target range or in the field. The invention is embodied in the form of a front sight for a gun or rifle that is primarily intended for target practice, but is by no means limited to such use; and is in fact well calculated to serve as a hunting sight also in localities where the game oers the hunter an opportunity to draw a careful bead.
The invention is shown in the accompanying drawing and described fully hereinafter; but We are by no means limited to the embodiment actually presented; for numerous changes in details may be made Without deviating from the essential structure in which the invention resides.
On the drawings:
Figure 1 is a side view partly in section of a gunsight according to this invention, shown on an enlarged scale.
Figure 2 is a front view of the apertured sighting disk which is an important part of the invention.
Figure 3 is a cross section thereof; and
Figure 4 is a view explaining the effect thereof.
The gun sight comprises a tube I of metal or any other suitable opaque material through which the shooter peers when aiming. It is open at both ends and contains a transparent disk 2, having a central opening 3. The disk 2 is mounted in transverse position against an annular shoulder 6 in the tube I and the edge of the opening 3 is finished at an angle so that it presents a surface 4 which is conical and truncated like the outside of a cone between two planes which cut the cone at right angles to the axis between the apex and the base. In other Words, the inclination of the edge is such that if the surface 4 were projected to the axis of this opening and of the tube I, the outline of a cone would result.
When this disk is supported in a member like the tube I, and when this member is opaque and has also a darkened interior surface, a very advantageous optical condition is created, and the shooter is enabled to judge the exact center of the opening 3 and line up this point accurately upon the target. To the eye of the rifieman aiming through the tube I, the area of the disk between the opening 3 and the tube is perfectly transparent, but the conical edge 4 of the opening 3 looks dark and gives the appearance of having a distinct dark lining, as if fringed with a ring of metal; and the outline of the opening 3 is thus defined very clearly. This fact is indicated in Figure 2 where the conical edge of the opening 3 is depicted as if it were an opaque ring affixed to the rim of the opening; and this vision is as pronounced in reality as the ligure shows it to be.
One end of the tube I, that is, the end presented to the eye of the marksman, has an inside screw thread 1, and this end of the tube receives a hollow sleeve 8 with outside screw threads 9 to engage the thread 'I and hold the sleeve 8 in place. The sleeve 8 can be turned in far enough to press the disk 2 against the shoulder 6 and the outer part of the sleeve 8 will have an outside shoulder IU between which and its adjacent extremity the sleeve is made somewhat thicker and milled or roughened on the outside and on the rim, so that it can be grasped by hand and easily turned. This milled effect is shown at II.
The gun sight is afxed to a firearm by mounting the tube I with the disk 2 therein adjacent to the front end of the barrel, Where the user of the gun can glance through it. For this purpose the tube is provided with a base I2, affixed thereto and having a groove I3 in the bottoni and a hole I4 for a tightening screw. By means of the base and the screw, the sight is secured in the proper position to cooperate with the rear sight at the back end of the barrel, so that the marksman can always center the target in the middle of the opening 3.
'I'he image or vision of a dark ring 5 around the opening 3 is due to the inclination of the edge or rim 4 of the opening. As the inside of the tube is iinished in some dark shade, such as blue or black, some rays of light reflected from the inside of and passing through the tube pass into the transparent disk, and some of these rays within the disk Will fall upon the surface 4 at such an angle with respect to the so-called critical angle, that these rays will be refracted and bent before passing out of the disk. Thus the inclined rim will show to the eye the dark color of the interior of the tube, which is preferably dull in nish and not polished.
This phenomenon is illustrated in Figure 4 Where l5 represents a ray of light in the disk 2, striking the conical surface 4 and so retracted that it is turned some to the front and some to the rear of the tube, where they fall upon the eye of the user of the sight.
The construction described gives the marksman a clear View of the target through the tube I, because the disk 2 of glass or the like is perfectly transparent and everything within the field of View delineated by the tube l around the opening 3 can be plainly seen. The rim of the opening 3 is sharply defined by the edge 4 thereof the tube serving as a darkening hood or screen for the disk 2; and the marksrnan is thus enabled to perceive the mark in front of the gun and to draw his bead by getting it directly in line with the center of the opening 3. By means of this device very accurate shooting, especially on target ranges, can be done, and most users nd it possible to add several points to their score as previously made.
The entire device is quite simple in construction and can be produced at 10W cost; no extra finish for the purpose of lining the edge 4 of the opening 3 is required. The working of it so as to bevel off the edge of this opening 3 at an inclination to the axis of the tu'be I and disk 2 is all that is needed to make the opening 3 easily discernible; and the dark ring effect of the bevelled edge l is present regardless of which side of the disk is turned towards the eye of the user.
It can be used with any adjustable apertured rear sight of conventional design.
Having described our invention, what we believe to be new is:
A gun sight comprising a tube having a shoulder therein between the ends thereof, a transparent disk in transverse position within said tube and engaging said shoulder, a sleeve in the tube holding the disk against the shoulder, the tube enclosing and screening the disk, the inside of the tube being dark hued, and the disk having an opening with a periphery which is inclined to the faces of the disk to reiiect the light rays to the inside of the disk to the walls of the tube, the surface of said periphery being of the same substance as the disk, said surface presenting towards the end of the tube the dark color of the interior thereof, making the periphery of the opening clearly discernible.
