GUN SIGHTS Filed Sept. 9, 1954 INVENTOR. FLORIAN SMECKO United States Patent GUN SIGHTS Florian Smecko, Madison, Wis.

Application September 9, 1954, Serial No. 455,020

10 Claims. (CI. 33-58) This invention relates to improvements in gun sights and is concerned more particularly with adjustable gun sights adapted to be removably attached to the rearward portion of a rifle barrel.

One of the objects of this invention is to provide a simple, inexpensive and practical gun sight well adapted to meet varying conditions of use.

Another object is to provide a gun sight which can be quickly and easily installed in an operative position.

Another object is to provide a gun sight which can be quickly and simply adjusted both at front and back.

Another object is to provide a gun sight which will be neat and attractive in appearance and yet be of such sturdy construction as to withstand hard usage.

Another object is to provide a gun sight which will lessen the possibility of brush-snagging because of its compact nature and clean design.

Another object is to provide a gun sight wherein light may be directed to a V-hairline wire.

Another object is to provide a gun sight wherein light directed to the V-hairline wire may be varied according to the brightness of the day.

Another object is to provide a gun sight which may be readily disassembled for cleaning.

Another object is to provide a gun sight which may be manufactured from light and inexpensive materials.

Other objects will be in part obvious and in part pointed out hereinafter.

This invention, accordingly, consists in the features of construction, combinations of elements and arrangements of the parts all of which will be fully described in the description to follow.

In the accompanying drawing in which is shown one of the various possible embodiments of my invention:

Fig. l is a side elevation of a gun having attached thereto a gun sight embodying features of the present invention;

Fig. 2 is an enlarged side elevation of the gun sight shown in Fig. 1;

Fig. 3 is a plan view of the gun sight as shown in Fig. 2;

Fig. 4 is an exploded fragmentary side elevation of the forward end of the gun sight;

Fig. 5 is a plan view of the gun sight as shown in Fig. 4; and

Fig. 6 is a fragmentary perspective view of the forward end of the gun sight partially disassembled.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now to Fig. 1, the gun sight, generally indicated at 1, is shown attached to the top rear of a rifle barrel 2. For purposes of illustration the gun shown is a rifle, although the present invention may be used with equal success on a shot gun or a rifle. The front peep sight 3 is of conventional construction and design and no claims are made to its novelty other than its cooperative effect.

As shown in Figs. 2 and 3, the main body of the gun sight 1 comprises a tubular member preferably of metal 'ice which rearward portion 5 slopes slightly, having a greater length at its bottom than at its top. A bar 6, substantially flat, is provided with a transverse, wedge-shaped foot 7 which is inserted in the transverse slot found on most conventional rifie and shot gun barrels to hold the gun sight in a rigid operative position. Disposed between tubular member 4 and bar 7 are elevating

means

8 and 10 which not only effect the raising and lowering of the gun sight but also attach the tubular member to the bar.

Elevating means 8 comprises a threaded bolt 11 revolvably mounted in the bottom of the forward end of tubular member 4. Secured rigidly to the projecting end portion of the bolt 11 is a disc 12, notched at its periphery 13 for firm engagement while making manual adjustment. The lower end of bolt 11 cooperates with a Lhreaded bore (not shown) extending through bar 6 and wage-shaped foot 7. Thus, rotational movement of disc 12 will readily raise or.l0wer theforwardend of the gun s1 At the rearward bottom portion of tubular member 4 is screw 14 which engages aligned threaded bores in bar 6 and member 4. The top of screw 14 is recessed and adapted to be turned with a small wrench. Tightening screw 14 presses its lower end against the rifle barrel effecting very slight elevation of the rear end of the gun sight further to adjust the same.

As best shown in Figs. 2 through 5, the forward end of the tubular member 4 is fitted with a removable sleeve 15. The purpose of sleeve 15 is two fold; it protects and locks the hairline wire in place and regulates the amount of light falling on the V-shaped sighting portion thereof. The horizontal V-hairline wire 16, as clearly shown in Fig. 6, may be secured to tubular member 4 in slots 17. Its ends 18 are preferably bent at right angles to its body to lie substantially fiat within small grooves 20 cut in the tubular member 4 at the ends of and at right angles to slots 17. Sleeve 15 then is snugly fitted over the end of tubular member 14 and the ends of V-hairline wire 16 thus locking this wire in place.

As best shown in Fig. 5, the upper forward portion of tubular member 4 is cut away, as at 21, directly over V-hairline wire 16. A bore hole 22 disposed rearwardly in sleeve 15 is so positioned that when the sleeve is in position light falls directly on the V-shaped sighting element of the wire 16 which also receives light through the bores 29 provided in opposed sides of the member 4.

Gun sight 1 is simply installed. The wedge-shaped foot 7 is slid in the usual transverse slot found on most rifles and/or shot guns on the market today. The sight is then adjusted for major corrections by raising or lowering forward elevating means 8. Fine adjustments are made at the back elevating means 10 which tends to tilt upward or downward the forward end of the sight, the forward elevating means 8 acting as a fulcrum. For controlling the degree of light to be admitted to the V-hairline wire 16 in accordance with visual conditions desired, the relative positions of the bore 22 and cutaway portion 21 may be selectively adjusted from a fully aligned open position to a completely offset closed position by relative rotation of the sleeve 15 with respect to the tubular receiving member 4.

It is to be understood that the present invention is not confined to the precise construction and arrangement of parts herein illustrated and described but embraces within its purview all such modifications thereof as come within the scope of the following claims.
