SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented Dec. 26, 1916.

To all whom t may concern:

Be it known that I, ROBERT A. MOORE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Sights for Firearms, of which the following is a specification.

in the peculiar formation of the slider employed, the provision of special adjusting means for the slider, and the formation of t-he slider and the base piece supporting the sight frame in such a way as to provide special advantageous sight members, along with other details of construction, all of which will be apparent upon reference to the accompanying description and the drawings annexed hereto, in which- Figure l is a perspective View of a sight embodying the invention, the same being illustrated in operative position adjacent to the breech of a firearm, the latter being partially illustrated in dotted lines. Fig. 2 is a vertical sectional View of the same. Fig. 3 is a sectional view taken about on the line 3-3 of Fig. 2. Fig. 4: is a cross section on the line 4 4 of Fig. 3; and Fig. 5 is a detail perspective View of the locking pins, finger piece, and washer, forming the adjusting means for the slider.

In the drawings, A designates the firearm to which the sight is applied and the sight itself is designated B. The sight B comprises the base piece 1 detachably connected with the breech of the gun by being formed with a dovetail at its lower portion and engaged in the customary way in a dovetail groove provided at the .front portion of the receiver of the breech mechanism. The base l is of peculiar formation, as seen best in Figs. 2 and 3. At one edge of the base l? the latter is. vformed with a sight member 2 notched as at 3 to provide an open sight of not unusual form. Said base l is provided at its opposite ends with ears 4 in which is mounted the pivot 5 by which the frame 6 of the distance sight is connected with the base. Intermediate the ears 4, the base l is provided with a depresssion 1a in which is seated a fiat spring 7, t-he ends of which are slightly elevated whereby the spring engages with the polysided lower ends of the sides of the frame 6. I The frame 6 carries the slider 8 which 1s of peculiar construction and said frame is adapted to lie in a position flat upon the breech of the weapon, and may assume the operative position illustrated in figures of the drawings by merely being elevated in an obvious manner. Owing to the coaction between the spring 7 and the lower ends of the frame 6, the movement of the frame into vertical or horizontal positions merely slightly depresses the ends of the spring 7 and the frame will be resiliently but positively held in either of its positions incident to the pressure of the spring thereagainst in the manner described. Furthermore, the sight member 2 constitutes a stop to limit the upward and rearward movement of the sight frame 6 in bringing the latter into operative position.

The slider 8 is formed with spaced grooves to receive the sides or legs of the frame 6, and the outer walls of said grooves are formed with ribs entering approximately U-shaped grooves 6 formed in the outer edge portions of the sides of said frame 6. Mounted on the upper portion of the slides 8 is the adjusting and holding means therefor, the same consisting of oppositely slidable locking pins 9 disposed horizontally on the slider and operating in openings suitably provided therein. Intermediate the pins 9 and transverse in relation thereto is the plunger 10 provided with the finger piece 11, and formed between its ends with the reduced cam portion 10. The inner ends of the pins 9 are rounded and adapted to engage the cam portion l0 of the plunger 10, while the outer ends of the pins are preferably pointed and adapted to engage in any of correspondingly opposite depressions or recesses l2 formed on the inner sides of the legs of the frame 6. Between the front side of the slider 8 and the finger piece 11, and encircling the plunger 10 is located a spring member 11fl which consists of a split washer with the terminals thereof deflected so as to normally tend to force the finger piece 11 outward and maintain the cam 10 in engagement with the pins 9 whereby to hold the latter in frictional or interlocking engagement with the frame 6, as the case may be. Obviously by slight pressure on the nger piece 11 the washer 11a will be compressed and the pins 9 will be relieved of the pressure of the cam 10 on plunger 10, thereby permitting of raising and lowering of the slider 8 to any desired position of adjustment.

The slider 8 is provided with a downwardly extending flange or lsight member 12 having the peep-hole sight 13, and in its body po-rtion the slider S is formed with the notched hole 14 providing an auxiliary large peep-sight. Furthermore, in its upper edge the slider S is formed with a sight notch 15 useful as an open sight somewhat similar to the open sight 8.

As will be observed by reference to Fig. 2, the slider 8 is adapted to be adjusted so that the peep-hole 13 may be brought o-pposite the open notch sight 3 and the fixed range usefulness of the open sight practically converted to a fixed range peep-sight, in an obvious manner.

Having in view the peculiar form of the slider 8, it will be understood that in the assemblanee of the parts of the sight, the slider is placed upon the frame 6 previous to the connection of the frame with the base 1 by means of the pivot 5. It will be also noted that a bushing 16 surrounds the pivot 5 between the legs or sides of the frame 6.

-Having thus described the invention, what I claim as new is:

1. In a gun sight, the combination of a base, a frame mounted on said base, a slider mounted on said frame and movable with the latter into operative and inoperative positions, spring pressed pins mounted on the slider so as to engage the frame and hold the slider at predetermined adjustments on the frame, said slider being provided with sight means, and means common to the pins to control the action of the same.

2. In a gun sight, the combination of a base, a frame mounted on said base, a slider mounted on said frame and movable with the latter into operative and inoperative positions, a sight member carried by the base,

the sight member aforesaid, and holding the slider being formed with sight means adapted to be adjusted for coperation with means for maintaining the slider at predetermined adjustments on the frame.

3. In a gun sight, the combination of a base having a sight member provided with a sight notch, a frame movably mounted upon said base, a slider carried by said frame and provided with a peep-sight, and holding means for maintaining the slider at predetermined adjustments upon the frame adapted to interlock the slider and frame so that the slider is positioned with its peepsight alined with the sight notch of said sight member.

ll. In a gun sight, the combination with a base, of a sight frame supported thereon, a slider mounted on said frame and having sight means, spaced locking pins mounted on the slider and engageable with the frame, a plunger mounted between said pins, and means to operate said plunger to control the coaction between the said locking pins and the frame.

5. In a gun sight, the combination with a base, of a sight frame supported thereon, a slider mounted o-n said frame andfhaving sight means, a locking pin mounted on the slider and engageable with the frame, a plunger mounted on the slider, a linger piece for moving the plunger transversely to the line of movement of the locking pin for actuation of the latter, and means for-holding the plunger in a position whereby to normally maintain coaction between the locking pin and said frame.

6. In a gun sight, the combination with a base, of a sight frame supported thereon, a slider mounted on said frame and having sight means, a locking pin mounted on the slider and engageable with the frame, a plunger mounted on the slider, a finger piece for pressing the plunger, said plunger being provided with a cam engaging the locking pin to hold the latter engaged with the frame, and spring means cooperating with the plunger to maintain said engagement of the locking pin and compressible to permit disengagement of said pin.

7. In a gun sight, the combination of a base, a frame supported thereon, a sight slider mounted on said frame, holding and locking means intermediate the slider and frame consisting of oppositely movable locking pins mounted on the slider and adapted to engage said frame, a plunger movable transversely to and between said pins and having a cam to engage the pins, a linger piece for pressing the slider to release the pins from the cam action of said cam, and a spring member consisting of a resilient spring washer interposed between the finger piece of the plunger and the slider and normally tending to hold the latter in position maintaining locking engagement of the pins with the frame.

In testimony whereof I aflix my signature.

ROBERT A. MOORE.
