To all whom it may concern:

Be it known that I, DANIEL Hown NEILLY, a citizen of the United States, anda resident of Bradford, in 'the countyof Mc- Kean and State of Pennsylvania, have invented certain new and useful Improvements in Clasps, of which the following is a specification. a The present invention relates to an vimprovement in clasps, especially adapted for use with rifle straps or the like.

The object of the invention is to pro? vide an improved clasp of this. character 1 which is of simple and durable construction, reliable in operation and easy and inexpensive to manufacture, which automatically exerts a powerful gripping or clasping action upon the sections of'the rifle strap towmaintain them in desired position, whichis readily and easily adjustable and is quickly and uniformly effective in any position to ,which'it may be adjusted. Y 1 Other objects and advantages of the invention reside in certain novel features of construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in'thelappended claims, reference being had to the accompanying drawings forming part of this specification, and in which;

The clasp which is designated generally at Cris arranged upon the sections of the strap and has for its function the formation of the loop and the preservation of the loop inthe proper position upon the upper arm of the user.

\ The clasp comprises a frame 1Ov which includes a. plate 11 having oneend roughened,

as at 12-, and constituting a jaw, andvside flanges 13 extending at rightangles from each side of the plate and preferably formed integral therewith. A pivotpin 14 islprovided and hasits ends arranged in suitable bearings provided in the side 'flan es of the l frame and thereby constitutesa fu crum for the plate-11. y f f A coacting late 15 having a roughened portion 15 constituting a jaw isTarranged 11 and the c'oacting plate 15 short lever o arms which constitutes the jaws of the clasp and long lever arms which function to 0p:

the loop of the rifle strap must encircle the upper armabove or adjacent the upper porti'on of th'e biceps,.n1ust be :inaintain'ed in In practice, expertgriflemen and, sharp this position and must not be permitted to slide down the arm toward the elbow. The leather keeper and other devices heretofore proposed in the art have not been efiicient to maintain the loop in proper position and prevent its sliding down toward the elbow in the manner referred to. With my improved clasp however when the loop is positioned on the arm the loops 1'? and 18 are pressed inwardly by the fingers of the righthand of the rifleman and the clasp is slid along the sections of the strap until the loop of the proper size is formed, the loop having of course been properly positioned on the upper arm. Now then, when the strain is placed upon the ride strap it will spread that portion of the sections 8 and s which constitute the loop Z and these portions of sections 3 and 8 act upon the lips 17 and 18 to spread them or throw them outwardly away from each other. The lips being formed upon the long arms of the lever throw the short arms which constitute the jaws into powerful gripping engagement with the sections of the strap thus binding the sections together and the clasp to the sections. It is to be noted moreover that the heavier the strain the more powerful the gripping engagement. with the sections of the strap bound together it is impossible for the loop to slide down the arm as it cannot enlarge and will be maintained in proper position.

In Figure 5 there is shown a modified form of the invention especially adapted for use with canvass straps or slings. The canvass straps or slings have hooks riveted to both ends and these prevent the strap being passed through the clasp without taking out the rivets. With these canvass straps a clasp designated at 20, is employed and includes a pair of resilient arms designated at 21, connected to each other by means of a curved resilient spring member 22 and terminating at their free ends in hooks or gripping portions 23. In the use of this form of clasp the hooks or gripping portions 23 are utilized to spread the gripping portions of the clasp in order to associate it with the strap and when so associated these hooks are released and the resilient arms allowed to spring into engagement with the strap.
