GUN-SIGHT.

SPECIFICATION forming part of Letters Patent o. 607,344, dated July 12, 1898. Application tiled May 6, 1897. Serial No. 635,325. (No model.) V

To @ZZ whom t may concern.-

Be it known that I, JOHN A. COOPER, a citizen of the United States, residing at Adair, in the county of Adair and State of Iowa, have invented certain new and useful Improvements in Gun-Sights 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention hereinafter fully described and claimed and illustrated in the accompany` ing drawings relates to gun-sights, the object being, among others, to provide a sight for any variety of shooting appliance which will at all times reliably perform its office, enabling the user to accurately draw a bead upon an object without embarrassment arising from the use of many sights as now constructed.

By the use of my invention, employing, as it does, a transparent or translucent substance, all this annoyance arising from the use of metal sights is avoided, making it possible to eect an absolutely perfect alinement of the cooperating features of my improved gunsight.

It will be seen from the following specification that the construction employed is of a simple and inexpensive character, enabling the sight to be readily applied or removed from its operative position upon the gun, and while Ihave described the preferred accessories of the various parts it will be seen that their equivalent is comprehendcd by me.

I n the accompanying drawings, Figure 1 is a side elevation of a gun, showing my invention as applied to use. Fig. 2 is la longitudinal central section of the rear sight. Fig. is a top plan view thereof." Fig, 4 is a front elevation thereof, showing a simple vertical line as the registering-point; Fig. 5 is a front elevation showinga simple notch as the registering-point, while Fig. 6 is a similar View having an aperture as the registering-point. Fig. 7is a front view of the front sight, wherein a piece of transparent substance is provided upon its upper edge with an insert with which the registering-point on the rear sight cooperates. Fig. 8 is a side View of Fig. 7, while Fig. 9 is a vertical central section of Fig. 7. Fig. 10 is a side view showing a vaholding the near sight, while Fig. 1l is a front View thereof.

In carrying out my invention I provide a suitable means for anchoring the rear sight in position,consistin g preferably of the bar l, having the wedge or anchoring section 2 and they slotted rear end 3, designed to receive the graduated regulating-bare, having the lateral ears 5 for easy manual control.

The vertically-disposed sight-holdin g frame 6 is attached to or integrally formed with the slotted end 3 and is provided with the upwardly-extending guides 7 and the laterally-A extending ears 8. The inner edges of the guides 7 are provided with vertically-disposed grooves 9, designed to receive the edges of the sight proper, l0, formed, preferably, of glass, Celluloid, or anytransparent or translucent substance.

The sight proper, 10, is held in the seat and is adjustable therein by means of the setscrews 11 or by other preferred means, and may be provided in its central part with the vertically-disposed line. 12, the' notch 13 in its upper edge, or the aperture 14, as shown in Figs. 4, 5, and 6. It will of course be understood that any equivalent of the registering- points 12, 13, and 14, as a simple crossmark or otherwise, may be employed, the object being to locate the point of registration away from the metallic parts in order that the eye may be unaifected thereby.

The front sight, which is designed to coperate with the rear sight, is preferably constructed as shown in Figs. 7, 8, and 9, though any suitable means may be substituted there for.

In Fig. 7 I have shown the device as being anchored or held in position by the downwardly-tapered base 15, designed to be received by a dovetail transversely-disposed seat provided in the 'gun-barrel, this being substantially the usual means employed for anchoring a sight. Upon the base thus provided I erect the annular holder 16, the lower half or less being provided with the side walls or flanges 17, designed to provide a seat for the rounded edge of the semidisk 18, made of glass or some translucent substance and provided on its upper edge with the registering l ried construction for the means employed for IOO point 19, formed of any suitable substance and preferably red in color. I prefer to give suiiicient width to the annular holder 16 to provide a suitable housing or shadow for the registering-point 19. The object in using a red registering-point at this place is to make it more readily discernible, as that color would more clearly' distinguish it from the usual color of surrounding objects.

The body of the sight 1S is held in position by the set-screws 20, and it may be removed from the seat thus provided by slightly withdrawing said screws and reversing its position, when it may be easily removed, as the iianges 17 will no longer engage with the edge thereof.

In Fig. 7 I have indicated by dotted lines 21 the position occupied by the top edge of the sight when in an inverted position, the position of the registering-point 19 being indicated by dotted lines 22 when in such position.

In Figs. 10 and 11 I have shown a varied construction for holding the rear sight in position, the holder 23 being provided upon its inner edge with an annular groove 24, designed to receive the edge of the sight 25 and reliably hold it in an adjusted position. This construction is perhaps not so convenient for removing or replacing the sight as that illustrated in the other figures of the drawings, though it will be found to be of a reliable and permanent character.

Vhile I have signiiied a preference that the registering-point 19 may be made to have a red color, yet I do not Wish to be confined strictly to this selection, as a registering-point of other colors may be found desirable.

If deemed a better construction, one or both of the surfaces of the substance forming both sights may be slightly roughened or ground, which, if glass is employed, will produce the desired degree of translueency found desirable in' some cases.

Believing that the construction and advantages .of myinvention in gun-sights are made fully apparent, I will dispense with further reference to the details thereof.

I-Iaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A rear sight of glass having a central vertical line thereon, a front transparent sight having a registering pointed projection of a different color on its upper side, all arranged as set forth.

2. An integral circular rim having a widened lower half with a groove therein holding a selnicircular sight, and means to retain said sight in place, whereby on removing said means, the sight by a half-turn can be removed, all arrangedas set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. COOPER.
