GUN-SIGHT.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application filed January 17, 1918. Serial N 0. 212,309.

To all whom it may concern:

Be it [known that I, WILLIAM ELLIOTT, a citizen of the United States, and a resident of Marshfield, in the county of Coos and State of Oregon, have invented certain new and useful Improvements in Gun-Sights, of which the following is a specification.

My invention is an improvement in gun sights, and has for its object to provide a fore sight of the character specified, wherein the sighting element is adjustable vertically with respect to the gun, and wherein the sight is detachable to permit the use of different types of sights.

In the drawings:

Figure 1 is a partial side view of a gun barrel having the improved sight;

Fig. 2 is a longitudinal section through the sight;

Fig. 3 is a section on the line 33 of Fig.

Figs. 4, 5 and 6 are front views of different types of sights.

The present embodiment of the invention is shown in connection with a gun barrel 1 which has the usual undercut transverse groove 2 for receiving the undercut base 3 of the sight support 4. This sight support has the usual longitudinally extending central rib, which is cut away or reduced at the rear end of the support as indicated at 5, to form a vertical shoulder 6 at about the center of the rib, behind which the bead of the sight is mounted.

The sight, shown more particularly in Fig. 4, is mounted in a vertical opening 7 passing through the sight support just in rear of the shoulder 6, and the sight has annular grooves 7 which are adapted to be engaged by the holding means to hold the sight in adjusted] position. The sight is movable vertically in the opening 7 and is held in adjusted position by a transversely arranged pin 8. This pin is mounted to move in a transverse opening 9 in the sight support, and is provided at each end with a trans versely kerfed head 10 and 11, respectively. The head 10 is of greater diameter than the head 11 and moves in an enlarged portion 12 of the opening 9.

A coil spring 13 is arranged between the head and the shoulder formed between the body of the bore and the reduced portion, and the spring normally acts to hold the parts in the position of Fig. 3. It will be noticed that the body of the pin is reduced between the spring, and this reduced portion is tapered. The tapering portion engages the groove 7 of the sight, as shown in Figs. 2 and 3, to hold the sight in adjusted position. By pressing the head 10 inwardly to compress the spring 13, the smallest portion of the tapering portion of the pin may be brought into register with the sight opening 6 to release the sight pin to permit it to be raised or lowered, as the case may be. Thus two adjustments are permitted for the sight shown in Figs. 2 and 4.

In Fig. 5 the sight 13 has three grooves 15 for engagement by the pin, and three adjustments are permitted. *The sight shown in Fig. 16 has two grooves 17, and has a differently shaped head or bead. Each of the three sight pins shown in Figs. 4, 5 and 6 have differently shaped beads, as shown, and it will be obvious that any form of bead might be provided, and as many adjustments as might be found necessary. When the sights are in adjusted position, the pin 8 firmly holds them in such position, and the spring 13 prevents accidental displacement of the pin.

I claim:

1. A gun sight comprising a support for attachment to a gun, said support having a longitudinally extending rib cut away at its rear end to form a shoulder at approximately the center of the support, and having a vertical opening in rear of the shoulder, a transverse opening intersecting the vertical opening, a sight comprising a pin carrying a bead at its upper end and having annular grooves at its lower end in the vertical opening, a pin slidable in the transverse opening for engaging the groove to hold the sight in adjusted position, a spring normally pressing the pin in one direction, the pin having a head for limiting its movement in the said direction, and the pin having a tapered portion adapted to move into register with the groove to release the sight pin when the spring is compressed.

2. A gun sight adapted for attachment to a gun and having a vertical opening intermediate its ends and a transverse opening intersecting the vertical opening, one of a set of interchangeable sights engaging the vertical opening, each comprising a pin having a head at its upper end and annular grooves at its lower end, and a locking pin in the transverse opening and extending into the vertical opening to engage the grooves, said pin having a reduced portion annular grooves, a support having a vertical adapted to register With the grooves to reopening for the pins, and a locking pin lease the sights. movable transversely of the said opening and 10 3. A gun sight comprising a support and engaging the grooves to hold the pins in ad- 5 a series of interchangeable sight members justed position.

therefor, each member consisting of a pin having a bead at its upper end and having WILLIAM ELLIOTT.
