Patented May 21,l 1935 UNITED STATES PATENT OFFICE GUN SIGHT Charles F. Lefever, Plymouth, Mich., assgnor to Daisy Manufacturing Company, Plymouth, Mich., a corporation of Michigan Application September 12, 1932, Serial No. 632,856

2 Claims.

The invention relates to guns and more particularly to spring air guns having removable shooting barrels and magazine barrels associated therewith, and the invention consists, first, in the peculiar construction of the sights for the gun barrel; second, in the construction of the removable shooting barrel; third, in the means for locking said shooting barrel in position and for simultaneously controlling the closure for the shot opening in a magazine barrel, and further in various details of construction as hereinafter set forth.

In the drawings:

Figure 1 is an elevation of the gun;

Figure 2 is an enlarged sectional elevation showing the construction of the sights for the barrel and also the locking means for the removable shooting barrel;

Figure 3 is a longitudinal section through a false barrel and shooting barrel;

Figure 4 is a perspective view showing the interlocking portions of the false barrel and shooting barrel;

Figure 5 is a perspective view showing a portion of the gun barrel with the rear sight removed therefrom;

Figure 6 is a cross section substantially on line 6 6 of Figure 3;

Figure 7 is a rear end elevation of the sight.

Figure 8 is an end elevation of the false barrel with the true barrel removed.

Sights for gun barrels are generally formed by a bead member at the forward end thereof and a perforated plate at the rear end. It frequently happens that in shooting, light shining on the perforated plate and into the aperture therein and also on the bead will interfere with proper sighting. With the present invention, I have cured this defect by surrounding both the bead and the apertured plate with tubes of suiiicient length to shield the same from side lights. I have also provided means for removably mounting the rear sight tube upon the barrel and for holding the same in proper alignment therewith. As shown, A is the stock, B the false barrel, C the frame, and D the pivoted lever for use in compressing Athe spring which actuates the air plunger. As the specific construction of spring pressed plunger and actuating mechanism therefor forms no part of the present invention, I deem it unnecessary to further describe or illustrate the same.

My improved sights include a forward sight E which projects upward from the false barrel D and provided with a bead portion E', also a rear sight F which is formed with an aperture F' therethrough through which the bead E is sighted. The member F is preferably formed of a sheet metal cup which is inserted within a tube G being welded or otherwise secured therein at a point midway between the ends of said tube. The tube G is secured to the barrel B by means of a tongue G at its forward end which engages a struck up socket B on the barrel. At the rear end of. the tube G is a projecting ear H which is fashioned to t against the top of the barrel to which it is secured by a screw I passing through the frame C and into the stock A. Between these forward and rear points of attachment is a saddle J which is preferably formed by an upwardly projecting portion of a spring abutment K secured within the frame. Thus the saddle J which ts about the tube G will properly align said tube while the tongue G', ear I-I and screw I will secure the same in position.

HeretoforeI guns have been provided with detachable shooting barrels such as L which are detachably positioned within the false barrel D while the space within the latter barrel surrounding the shooting barrel is utilized for forming a magazine or shot reservoir. The present construction includes this feature but I have devised a novel means of locking the shooting barrel in position which also cooperates to form a closure for the' feed opening into the magazine. As shown, the barrel L is provided at its rear end with a tapered portion L which fits within the abutment M for the plunger (not shown). A guide N surrounds the b-arrel L adjacent to the abutment and serves to direct the shot into a channel N vfrom which they passI successively through an aperture N2 into the barrel L. At the forward end of the barrel L is a cap member O which is formed of a cupped sheet metal blank having its body portion O drawn inward to a smaller diameter leaving a return bent iiange O2. The center of the cap is perforated with an inwardly extending flange O3 which fits about the shooting barrel L and is attached thereto. The body portion O has a cut away portion O4 for registration with a shot feed aperture P in the false barrel in one position of rotative adjustment. This body portion also has struck out therefrom a lug O5 which serves as a guide for inserting the cap in the false barrel and also as a lock for retaining it in position. Cooperating with the cap member O and lug O5 thereof is a reinforcement member fitting within the false barrel B and this member is formed as a part of the sight member E previously de- Wigwam scribed. Thus as shown, the sight member E is formed as an upwardly projecting ange on a cylindrical member E2 which extends part way around within the false barrel B, leaving a gap which forms an entrance channel E3 for the lug O5. The portion E2 is also cut away at E4 to permit the turning 'of the cap O after the lug O5 has passed through the channel P3 and the edges E5 and E6 of this cut away portion form shoulders for respectively holding the cap against longitudinal or further rotative movement.

With the construction just described, when the barrel L is inserted within the false barrel B, its inner end L' will engage the aperture in the abutment M and the lug O5 on the cap O will l enter the channel E3. The cap and barrel are moved inward until the lug O5 passes beyond the shoulder E5, after which the cap may be adjusted rotatively. This forms in effect a bayonet lock which holds the shooting barrel from accidental displacement. It also serves the function of a valve or closure for the shot feed aperture P as in one position of rotative adjustment the cui"l away portion O4 is in registration with this aperture to permit of introduction of shot, while in the locked position the aperture P is closed by an imperforate portion of the body O.

To protect the forward or bead sight from confusing side lights, a tube is arranged to surround the same. As shown in Figs. 4 and 6, this tube Q is formed from sheet metal blank with laterally extending segmental anges Q on opposite sides thereof which are welded or otherwise secured to the false barrel.

WhatI claim as my invention is:

1. The combination with a gun barrel provided with a spring abutment therein, the end of said abutment extending upward through a slot in the barrel and fashioned to form a saddle, of a rear sight formed of a tube mounted above said barrel and provided with a centrally perforated disk arranged therein intermediate the ends thereof, said tube being secured to said barrel and resting upon the saddle at the upper end of said spring abutment.

2. The combination with a gun barrel and stock, of a spring abutment within said barrel having its upper end projecting through a slot therein fashioned to form a saddle, a rear sight comprising a tube mounted on said barrel and resting upon and guided by said saddle, the forward end of said tube having a tongue for engaging a struck up bearing on said barrel and the rear end of said tube being secured to said stock and an apertured disk secured within said tube intermediate the ends thereof.
