HAND SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 603,238, dated April 26, 1898.

Application led April 19, 1897.

To all whom it may concern: f

Be it known that I, JOHN NURNBERGER, Jr., a citizen of the United States, residing near Atherton, in the county of Park and State of Indiana,have in vented certain new and useful Improvements in Hand Snap-Hooks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. l

My invention relates to hand snap-hooks of that class that are adapted to be used upon harness, and has for its objects to produce a hand-snap that can be readily operated with one hand, that will be normally closed at all times and practically looked when not in the act of being snapped or unsnappedby the operator, and that will be simple in construction and cheap of manufacture.

The invention consists in the particular combination of parts for the purposes named, which are shown in the accompanying drawings and described in the following specification. Y

In the drawings, Figure l is a side view having the open position indicated by dotted lines. Fig. 2 is a top plan view. Fig. Sis a Sectional view on the line 3 3 of Fig. 2, and Fig. 4 is a front end view.

The hook proper consists of an eye or loop A, adapted to receive a harness-strap, the shank B, and the hook C. A spring-steel tongue D, having its free end slightly upturned and beveled to meet and fit upon the end t' of the hook C, is riveted to the shank B near the loop A by the rivet E and is adapted to assume the position indicated by the' dotted lines in Fig..1 when free to do so. A iiat ring F, having the central opening 0, encircles the shank B and the outwardly-opening tongue D and is Vfree to slide thereon. A coil-spring G surrounds the shank B and tongue D and is adapted to press at the rear end against the shoulders la of the loop A and at the front end against the ring F, thereby holding said ring normally against the shoulders n, formed on either side of the shank B sesamo. 632,887.

as straps for said ring. The opening o in the ring F is of such size that when the ring is slid forward by the coil-spring G against the shoulders n, which is its normal position, the tongue D will be brought into contact with the end t' of the hook C, thereby closing the hook, and said tongue will be completely locked in that position until the ring F is pressed back, as shown in Fig. l by the dotted lines, when the tongue D will spring back,

the hook C from catching behind said tongue, f

thereby making it troublesome to operate quickly. Another advantage of the outwardly-opening tongue is to admit larger bodies within the hook C than could enter with the inwardly-opening tongue.

I am aware that spring-controlled snaphooks of various forms have been used heretofore. Therefore I do not broadly claim a snap-hook adapted to be closed by a spring; but

What I claim, and desire to secure by Letters Patent of the United States, is-

l. In a hand snap-hook, the combination of a hook consisting of a loop A, a shank B, having shoulders n, and a hook C, with a Vspring-steel tongue D, riveted to said shank B, near the loop A, said tongue being adapted to spring outwardly when released; a flat sliding ring F, having a central opening o, to receive the shankB and tongue D; a coil-spring G, surrounding said shank B and tongue D, having its bearing at one end against the shoulders 7o of the loop A, and at the other end against the inner face of the flat ring F, thereby pressing said ring against the shoulders n,'of the shank B, and normally securing the tongue D against the end t', of the hook C, all as shown and described.

2. In combination in a hand snap-hook of IOO Io G, surrounding said shank B, and tongue D,

and normally pressing said ring F, against the Shoulders n, on said shank, thereby securing the free end of the tongue D, against the end i, of the hook C, as set forth.

In testimony whereof I affix my signature 15 in presence of two witnesses.
