10 Claims.

This invention relates to sling strap connecting devices and more particularly to improvements in sling strap swivels and in the means to connect the same to a gun or the like article. Sling straps for guns are generally used for carrying them hung across the back of and from,

the users shoulder, and for steadying the gun during its use in shooting. The ends of these by swivels, being disother disposed intermediate this end and the muzzle end of the gun.

It is desirable that provision be made to shorten the distance between these points, preferably by moving the intermediate connection rearwardly toward the butt end, to compensate for differences in stature of diiierent users so that the gun will be comfortably and properly positioned and balanced while being so carried. It is also desirable,

when the gun is to be used for shooting to be able to quickly and readily change the degree of looseness of the strap. Due to the present form of necting devices this strap conrequires the lengthening of the strap between its holding swivels by unbuckling its ends and adjusting its length to suit, which is inconvenient and time consuming. One of the principal objects of this invention is to provide means to adjustably connect a sling strap to a gun or the like, whereby desired changes in length and degree of looseness of the strap between the points of its connection with the gun, may be quickly and readily made.

Another object is to provide mean tively position and connect one of the s to selecsling strap swivels to the gun or like article in any one of a plurality of positions to obtain the above mentioned desiderata.

Still another object is to provide means to detachably connect a sling strap swivel ber connectable to a to a memgun part and which may include means to releasably lock the same to said member.

A further object is to provide means in'the gun or like part of the swivel in to locate the swivel in operable posito the gun, and to releasably lock this invention to prof generally device will be simple, durable and inexpensive in construetion, as well as convenient, practical, and eflicient in its use.

serviceable With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed. 5

Figure 6 is an enlarged sectional view somewhat similar to Figure 3, taken through a sling strap swivel, and showing by the use of dotted lines the operation and position of the several parts thereof when removing it from the gun;

Figure '7 is a plan view of the parts shown in Figure 6;

Figure 8 is an enlarged sectional view on line 8 -3 of Figure 2, and 30 Figure 9 is a detail view of a spring part of the device.

The arrangement and structure of the parts whereby the device of this invention may be quickly and readily connected to a gun or like article to obtain the advantages and results contemplated and particularly whereby one of the sling strap swivels It! or I I may be selectively positioned in any one of a plurality of positions, disposed lengthwise of the gun l2, comprises a 40 bar or plate 13 securable to the gun 12 by means of screws l4 and co-operating means between the plate l3 and one of the strap swivels, in this instance, swivel Ill. The plate I3 is preferably disposed, as herein shown, in a recess l5 formed 45 in and adjacent to one end of the gun stock IS. A bracket l1 secured adjacent the other end of the gun stock 5 by screws I8, is provided to which the swivel Il may be releasably secured by similar co-operating means between this bracket and the swivel H. V

The co-operating means between the swivels l0 and H and the plate l3 and bracket l1 respectively, comprises a tongue IS on one, herein shown on the swivels, and a slot 20 in the other, herein of a gun having a sling the shown, one slot in the bracket i1, and a plurality of slots, spaced apart lengthwise of the gun, in plate I3. Each of the slots 20 is formed with a central circular opening 2| with extensions 22 at both sides thereof which are narrower in dimension than the diameter of the opening 2|. The tongues l9 are elongated to easily pass through the slots 20, when disposed in alignment therewith, and be disposed beneath the plate I 3. When so disposed the tongues iii are turned, by rotation of the respective swivel, at right angles to their aligned position with the slots 28, whereby the ends thereof overlap the plate i3 at each side of the central opening 2|, thereby preventing removal of the tongues from the plate. A counterbore 23 is formed in the gun stock It, concentric to each of the spaced apart openings 2| in the plate l3, to permit the turning of the tongue l9 and the bracket II is struck outwardly, as at 24, for the same purpose.

The tongue I9, of each swivel in, II, is spaced from a cylindrical body portion 25 of each, an amount substantially equal to the thickness of the plate l3, or bracket l1, and is connected thereto by a cylindrical neck 25. The diameter of the neck 26 is slightly less than the diameter of the opening 2|, to permit its insertion and rotation therein. By this arrangement the neck 26 forms centralizing means for the tongue 59 in respect to the slot 23, and a trunnion, fitting the opening 2| which acts as a bearing for the respective swivel. An elongated loop or bail 21, having its spaced apart

ends

28 and 29 opposed and inserted in a suitable transverse bore 33 provided in the body portion 25, is provided, to support the sling strap 3| in the usual manner.

In order to releasably lock the swivels l3 and I! with the tongue l9 thereof disposed crosswise of the slot 20 of the plate l3 or the bracket l7, and to secure to, and centralize the bail 21 with, the body portion 25 of the respective swivel, a resilient member 32 is provided, which is disposed in an axially directed groove 33 formed in the body 25. The groove 33 extends lengthwise through the body 25 at one side thereof and is adapted to be disposed in communication with one of the slot extensions 22 when the respective swivel is in its assembled position, with the plate E3 or bracket H, as shown in Figure 6. The resilient member 32 is herein shown formed of a flat spring metal strip extending from one side and at the top of the body 25, across the same to the other side, and. is then bent as at 34, and extends downwardly and toward the first side adjacent the bottom of the body 25. Adjacent the bottom of the body 25, the member 32 is bent to form a loop 35, and is then extended upwardly and outwardly beyond the first side of the body 25, and has its end formed into a finger engaging circular loop 36.

The end 31 of the resilient member 32, adjacent the top of the body 25, is provided with transversely extending

ears

38 and 39 which are disposed in an annular groove 43 formed in the periphery of the body 25, closely adjacent its top surface. The material of the body 25 is crimped tightly down upon the

ears

38 and 39, disposed in the groove 46, to close the groove and clamp the ears therein. The portion 8| of the member 32, which extends downwardly and toward the first side of the body 25, crosses the bore 33 and is thereby disposed between the opposed spaced apart

ends

28 and 29 of the bail 2?, preventing its transverse movement in respect to the body 25. The looped portion 35 of the member 32 is adapted to snap into the slot extension 22, to locate, and to indicate that, the tongue I9 is disposed crosswise of the slot 20 in position to hold the swivel to the plate |3 or bracket 1, and to releasably lock the respective swivel in its operative position and against being turned in respect to the plate or bracket. By pressing upwardly upon the finger loop 36, the loop 35 may be removed from the slot extension 22 and the swivel may be turned to align the tongue I9 with the slot 20, whereby the swivel may be removed from its supporting member, herein constituted by the plate l3 or bracket IT, as shown in dotted lines in Figure 6.

In using the device of this invention in association with a gun, the sling strap swivel is connected to the bracket l1, previously secured to the stock 6 by screws l8, as above described. The length of the strap desired is determined and the swivel I is connected to the plate l3, previously secured to the stock l6 by screws M, by inserting its tongue l9 into the desired one of the spaced apart slots 2!). Whenever it is desired to alter the degree of looseness of the strap or to shorten its effective length to permit the gun to be more comfortably positioned or balanced and efficiently used, the swivel I0 may be quickly released from the plate i3 and be disposed in the desired position relatively to the gun by inserting its tongue I9 selectively into any one of the slots 20, wherein it will be locked by the spring or resilient member 32 after it has been turned crosswise of the slot by rotation of the swivel. The provision of the member 32 in a device of this nature by which the sling strap swivels may be located and securely locked to their respective supporting or gun connecting members, and which also serves as a bail position retaining element, simplifies the manufacture of such a device and reduces the initial cost thereof, while retaining its eificiency and durability.

It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, and it will be further understood that each and every novel feature and combination thereof present in, or possessed by, the device herein disclosed, forms a part of the invention included in this application.
