Shot gun sight

Application filed December 26, 1928. Serial No. 328,532.

My invention relates to improvements in shot gun sights, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide a shot gun sight that carries a relatively large ivory or composition bead, white or any-other color so as to be readily seen. The bead has the appearance of being a full ivory bead to 10 the eye, but in reality the bead is protected by a sight made of metal.

A further object of my invention is to provide a device of the type described that has an opening for receiving a wrench or a key, 15 these tools being used for the purpose of screwing the sight down into the gun barrel. The key will not mar the sight as would a pair of pliers.

A further object of my invention is to pro²⁰ vide a device of the type described which is extremely simple in construction and which is durable and efficient for the purpose intended.

Other objects and advantages will appear ^2j as the specification proceeds, and the novel features will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings forming a part of this ap³⁰ plication, in which

Figure 1 is a vertical section through the device shown greatly enlarged;

Figure 2 is a view of Figure 1 looking from the right; and ³³ Figure 3 is a view of Figure 1 looking from the left.

In carrying out my invention, I provide a sight that has a threaded shank portion 1 and a spherical portion 2. The sphere is cut ⁴⁰ along the lines 3 and 4. The cut at 4 is very close to the midpoint of the sphere so that a person looking from the left in Figure 1 will think the circle made by the cut 4 is approximately of the same diameter as the di-^J ameter of the sphere.

The surface 4 is recessed as at 5, and the peripheral wall of the recess is threaded at 6. An opening 7 extends from the recess 5 to the surface 3.

³⁰ An ivory bead 8 or a bead made from a composition is mounted in the recess 5. The bead has a spherical surface which is a continuation of the surface of the sphere 2. The bead also has a disc-shaped projection 9 that has its periphery threaded for receiving the 55 threads 6. A shoulder 10 limits the movement of the bead 8 into place.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. 60

I have shown a portion of a gun barrel 11 in Figure 1, and have further shown a threaded bore 12 for receiving the shank 1. A wrench or a key is inserted in the bore 7 and is turned for threading the shank 1 into the cs bore 12. The key will prevent the surface of the sight from becoming marred.

The sight is turned until the bead 8 faces toward the rear of the gun. As already stated, the sight will appear to have its entire 70 head as being composed of ivory or other material, although in reality the bead will be protected by the metal portions of the sight.

Although I have shown and described one 75 embodiment of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope of the invention as claimed. so
