.SHOT GUN SIGHT Filed Dec. 26, 1928 INVENTQR. fA/V W /f/NG WW 54g ATTORNEYS.
Patented Mar. 29, 1932 UNITED STATES DEAN W. KING, OF SAN FRANCISCO, CALIFORNIA SHOT GUN SIGHT Application led December 28, 1928. Serial No. 328,532.
Hy 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 larg ivory or composition bead, white or anynihr color so as to be readily seen. The bead has the appearance of being a full ivory bead to the eye, but in reality the bead is protected by a sight made of metal.
A further obj ect of my invention is to provide a device of the type described that has an opening for receiving a wrench or a key, 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 provide 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 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 application, 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
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 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 diameter 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.
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 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.
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 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 head as being composed of ivory or other material, although in reality the bead will b e lprotected by the metal portions of the sig t.
Although I have shown and described one 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.
A gun sight having a truncated substantially hemispherical head providing two parallel flat faces, a threaded shank extending from said head and having its axis extending parallel with said faces, said head having an opening extending perpendicularly to and between said faces, and a complemental heini-spherical bead secured to said head to form with said head a substantially spherical sighting bead.
