GUN SWIVEL Filed Aug. 1, 1949 /N/EN TDR JOHN L CUNE.'
HTTDFQ/vi/ Patented June 23, 1953 UNITED STATES PATENT OFFICE 1 Claim. 1
This invention relates generally to the art of gun making and particularly to a gun swivel.
The main object of this invention is to provide a gun swivel which will be easy to attach andV release from a gun stock and in which the swivelling action is limited in order to prevent the strap from becoming twisted.
I accomplish this and other objects in the manner set forth in the following specification as illustrated in the accompanying drawing, in
Fig. 1 is a side elevation of a rie showing the position of the swivel.
Fig. 2 is a fragmentary section along the line 2-2 in Fig. 1.
Fig. 3 is a section through the device, showing it attached to the stock, the section being taken along the longitudinal axis of the gun.
Fig. 4 is a section taken along the line 4--4 in Fig. 3.
Fig. 5 is similar to Fig. 4, but showing the retracted position of the retaining balls.
Fig. 6' is a plan view of the nut used for the manner of attaching shown in Fig. 2.
Like numbers of reference refer to the same or similar parts throughout the several views.
Referring in detail to the drawing, there is shown a common form of rifle I having a stock II and grip I2, to the opposite ends of which it is desired to secure a gun strap I3.
Referring particularly to my invention, same will be seen to consist of a sleeve I4 having a closed end I and occupying a recess I6 in the stock II. A at headed wood screw I'I passes through the end I5 into the stock II. Within the open end of the sleeve I4 is formed a raceway I8.
A plug I9 is provided having a reduced end 20 which is slidable and rotatable within the sleeve I4. The reduced portion 2n has mounted therein a plurality of balls 2| which are radially movable and rotatable in the holes 22 which are slightly inclined with relation to the axis of the plug I9.
Within-the plug I9 is formed an axial bore 23,
`whose outer end 24 is counter-bored and whose end 25 is closed.
Within the bore 23 is placed a spring 26 which bears against the closed end 25. Within the bore 23 is a plunger 21, whose head 28 is slidable within the counter-bore 24. The plunger 21 has a 2 raceway 29 formed therein, within which the balls 2I normally travel when the swivel is to be separated; that is, when the plug I9 is to be withdrawn from the sleeve I4.
Beyond the raceway 29 is a third raceway 3l)v which engages the balls 2| under the pressure of the spring 26.
In order to limit the rotation of the plug I9 with relation to the sleeve I4, I have provided an indent 3| which normally engages the balls 2I and prevents their rotation beyond the limit of said indent 3|.
A strap ring 32 is provided for the plug I9 and t is of a shape common to such devices now in use.
In the form of the device shown in Fig. 2, which is exactly the same as the one shown in Fig. 3, the sleeve I4 is held in place by a machine screw 33 which extends into the nut 34 which clears the rifle barrel I0.
It can be seen from the foregoing that the device constructed, as thus far described, will permit the plug I9 to rotate with the balls 2I riding in the raceway 30.
In order to limit this rotation, the indent 3|, which is disposed between a pair of the balls 2 I, thereby limiting the rotation of the plug I9 to less than 240.
A gun swivel comprising a sleeve adapted to be recessed into a gun stock, said sleeve having a raceway formed therein, an indent in said sleeve extending into said raceway, a plug rotatably mounted in said sleeve, said plug having radial holes formed in the side thereof inclined with relation to the axis of the plug, a ball disposed in each of said holes, a plunger disposed along the axis of said plug having a pair of raceways formed around same of unequal depth, a spring within said sleeve urging said plunger outwardly in a manner to urge its shallower raceway against said balls and force same outwardly through said holes into the raceway in said sleeve.
