- 3Claims. (015-3347),

The present invention relates to improvements in gun-sights, and it consistsin the coni'bin'a tions, constructions and arrangement of parts hereinafter described and claimed.

The principal object of my invention is to providea gun sight having a well defined outline by means of which the piece carryingthe sight may be accurately 'aimed. I propose to accomplish this object by reflecting light onto the sigh so as to clearly define the sight-outline.

More particularly I provide a reflector in combination with a sight in such a manner as to cause'light to be directed against the sight, the reflector being arranged intsuch a manner as to not interfere with the normal use of the piece.

A further object resides in the coloring of portions of thesights so as to bring out the sight object and thus assist the marksman in aligning the sights.

A still further object is to provide sights of 1 the character described which may be readily attached to firearms with but slight alteration being necessary in the latter. 'I further provide sights that may be interchanged with the original sights of the pieces.

Novel means are also used for attaching the sights in place, and means are provided for shielding or protecting the reflecting surface associated with the sights against injury.

Other objects will appear as the specification proceeds, and the novel features will be set forth in the appended claims.

For a better understanding of my invention, reference should be made to the accompanying drawing, forming part of this application, in

which i I Figure l is a side elevation of a fire arm showing my invention embodied therein;

7 Figure 2 an enlarged sectional view of the 0 front sight illustrated in Figure 1;

Figure 3 a transverse section taken along line 3-3 of Figure 2;

Figure 4 a sectional view through a modified front sight;

Figure 5 a transverse section taken on line 5--5 of Figure 4; I

Figure 6 a side elevation of a further modified front sight;

Figure 7 an end elevation thereof;

Figure 8 a side elevation of a still further modified front sight;

Figure 9 a side elevation of another form;

Figure 10 a fragmentary elevation of rear sight illustrated in Figure 1; and

Figure 11 a modified rear sight.

In carrying out my invention, I provide a firearm or piece 1 with a front sight 2 mounted on the muzzle of the barrel 3, a reflector 4 arranged in a depression 4' arranged below and to the rear of the sight for directing light onto the latter, and 69 a rear sight 5 disposed adjacent to "the breech 6.

Various means may be resorted to for fastening the front sight to the barrel, and in the first form I show a' tongue 7 extending from the lower edge of the sight and secured in a recess fashioned in an enlargement 9 on the barrel by a pin 10, or other suitable fastening means.

The rear surface of the sight is drilled for receiving a sight object 11, and the latter may be colored and formed of semi-transparent material, 79 or any other suitable object maybe employed.

The rear sight is fashioned with a sight groove 12 therein, and in order that the outline of the groove 'may be clearly defined I have provided a white surface 13 inthe shape of an arc surrounding the end of the groove toward the gripping end of the firearm. The line of sight can be adjusted parallel with the axis of the bore, or the sight adjusted for compensating for lateral drift or other deviations by moving the sight along the 80 transverse groove 14 by two opposing set-screws 15 which latter bear against an extended portion 15 of the sight.

Referring now to Figure 11, it will be noted that the sight groove 12 is fashioned directly in the metal forming part of the breech.

The reflector and front sight may also be mounted on a special ramp 16 (see Figure 4) fitting over the original chair or lug 17, and anchored to the latter by a filler member 18 and a pin 18. The reaction imparted to the barrel as the projectile leaves the muzzle has a tendency to urge the ramp to the left in Figure 4, and I have accordingly provided an L-shaped end 16' on the filler with a relatively large surface adapted for 9 receiving the impact of the ramp. The ramp presents leg portions 18 arranged in straddling relation with the chair as shown in Figure 5.

This latter form is particularly intended for use with firearms in which the original sight is attached to the chair by a dove-tail arrangement. In applying my improved sight to such a firearm; the original sight is first removed, and the filler 18 is then engaged with the chair. The ramp is now moved endwise along the barrel until the end 16' of the filler is engaged with the shoulder 19' on the ramp, and a pin 18 is then introduced through registering openings in the ramp and the filler. This provides a relatively rigid construction, and the new sight can be applied to the firearm without necessitating any alteration in the latter.

In Figures 6 and 7 I show the front sight fashioned with an orifice 20 through which aim can be taken, and in this form the sight object is ring-shaped.

The reflector may also be carried by a short ramp 21 in the manner shown in Figure 8 and fastened to the barrel 3 by means of spring clips 22 that are arranged for partially encircling and embracing the barrel. The front sight in this illustration could be permanently attached to the barrel and the reflector removably anchored in place.

A further mounting for the front sight is disclosed in Figure 9 in which a tapered lug'23 extends from the undersurface of the 'sight and is adapted for endwise introduction intoan undercut recess 24 extending transversely the upper surface 25 of the barrel. The depression 4' in which the reflector: is placed is formed in the barrel proper in this modification. a 1

From the foregoing description of the various parts of the sights the operation thereof may be readily understood. The sights are attached to the firearm as previously mentioned, and the reflectors 4 in the several forms are mounted for directing light over the sight object, andthus the latter is clearly discernible to the marksman; The aim is further improved by virtue of the fact that the white arcuate strip surrounding the rear sight groove clearly outlines the latter. The refiectors are protected from injury by the walls surrounding the recesses in which the reflectors are positioned.

WhileI have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

I claim:

1. A gun sight mounting comprising a chair secured to the gun barrel and having a transverse undercut'groove, a filler having a tapered lug fitting in the groove and a flange fitting against the rear end of the chair, a ramp fitting over the filler and having a section bearing against the rear end thereof and having a longitudinal groove in its top face, a sight object; a supporting structurefor the same having a tongue fitting in the longitudinal groove, means for fastening the ramp to the filler and means for fastening the tongue :to the ramp. 2 A gun sight mounting comprising a chair secured to the gun barrel and having a transverse undercut-groove, a filler having a tapered lug fitting in the groove and a flange fitting against the rear end of the chair, aramp fitting over the filler and having a section bearing against the rear end thereof and having a longitudinal groove in its top face, a sight object, a supporting structure for the same having a tongue fitting in the longitudinal groove, meansfor fastening the ramp to the filler and'means for fastening the tongueto the ramp", the ramp having a depression and a refiector lying on the rear face of the depression for directing light on the sight object.

3. A gun sight mounting comprising a chair secured'to the gun barrel and having an undercut groove, a filler having a tapered lug fitting in the groove and a flange fitting against the rear end of the chair, a ramp fitting over the filler and having a; section bearing against the rear end thereof and having a sight object thereon, the ramp having a depression rearwardly of the sight object and a reflector disposed in the depression so as to be concealed therein and positioned for directing .light on the sight object.
