-SNAP-HOOK.

SPECIFMATON forming part of Letters Patent No. 693,194, dated February 1 1, 1902;y

Application filed June l5, 1901.

To all whom, t may concern/5 Be it known that We, EMIL WEBER and FRANK C FREY, citizens of the United States, j residing at and whosepost-oliice address is 1933 Court street, Baker City, in the county` of Baker and State of Oregon, have invented` newand usefulImprovementsinSnap-Hooks, of which the following is a specification.

Our invention relates to snap-hooks; and its primary object is to provide a device of this character in which the use of springs will be entirely dispensed'with, thus contributing materially to the du rabilityof the hook.

Further objects of the invention are to provide a snap-hook which may be quickly and easily manipulated and to insure a reliable fastening without liability of accidental disengagement of the ring or other connection to which the hook is secured.

The constructionl and characteristic features of the invention will be fully described hereinafter in connection with the accompanying drawings, vwhich form a part of this specification, and its points of novelty will be set forth in the appended claims.

In the drawings, Figure 1 is' a side elevation of a snap-hook embodying the invention Y with a ring connected thereto. Fig. 2 is a front elevation of the same. Fig. 3 is a front elevation showing the hook turned laterally, but not elevated sufficiently to permit of the disengagement of the ring therefrom. Fig.` 4 is a front elevation showing the hook turned and in raised position to permit of the disengagement of the ring. Fig. 5 is a central longitudinal section of the device, and Fig. Gis a side elevation of a slightly-modified construction of the improvement.

The frame of thel device comprises a shank-j 1 and an integral loop 2, adapted to receive a strap 3 or other connection. The shank 1 is formed with a longitudinal bore 4 and a depending extension 5, the latter serving as a stop for the hook, Vasv will be more fully re ferred to. The lower end of the shank 1 is liared and beveled to form projecting shoulders 6, and the upper end of said shank is beveledto form cam-surfaces 7.

8 designates the hook proper, comprising a rod inserted into the bore of the shank and bent at its lower end to form the hook 9 and at its upper end to form a stop-lug 10, adapt- Serial No. 64,740. f (No model.)

. edto-engage the upper edge of the front wall ofthe shank. The under surface 11 of the stop-lug A10 is of cam shape, so that when the hook is turned or twistedv to either side the said lug will ride up one or the other of the cam-surfaces 7, thus moving the hook 8 longitudinally. The inner surface 12 of the eX- tension 5 is hollowed out toafford play for the ring 13, attached to the hook.

The utility and operation of the improve ment will be readily understood from the illustration in the drawings and may be explained as follows: To connect the hook to t-he ring 'the' latter is turned back into engagement with the extension 5, as shown in Figs. 1, 2, and 5. It will be obvious that as long as any pullingstrain is imposed upon the ring 13 4the stop-lug 10 will be held firmly in the position shown in Figs. 1, 2, and 5. If, however, such strain is relieved and a slight lat eral movement of the' ring 13 is permitted, accidental disconnection of the ring and hook will not result, for thereason that the space between the endv of the hook 9 andthe flared adjacent shoulder 6 of the shank will be less than the sectional diameter of the ring l13, as clearly illustrated at 14 in Fig. 3. To release the hook from its engagement with thering, it is necessary that the hook be turned laterally to its full limit of movement, as illus trated in Fig. 4,'which widens the space be -tween the end of the hook 9 and the adjacent shoulder 6. sufficiently to allow the ring to be released. l

The modified construction shown in Fig. 6 is similar to that shown in the other figures, excepting that the extension 5 is shortened and the hook 9a is correspondingly elongated.

Thisaffords a more extended lateral-play of the connecting-ring.

It will be apparent that we provide a secure, simple, inexpensive, anddurable snap without the employment of spring's,rivets, screws, or other details commonly used in spring snap-hooks and that the entire device as above described comprises only two cooperating parts, which may be readily manipulated to connect or disconnect the hook.

We claiml. A snap-hook comprising a bored shank having an integral loop at one end and beveied adjacent to said loop to form ca1n-sur faces, and formed at its opposite end with an extension; and a hook consisting of a rod curved at; one end to form a hook adapted to bear against said extension, and bent at its opposite end to form a stop-lug adapted When turned to ride upon one or lhe other of the cam-surfaces of the shank.

2. A snap-hook, comprising` a shank formed with a longitudinal bore, and beveled at one end to form cam-surfaces and having an extension and laterally-projecting shoulders at its opposite end; and a hook proper extending through the shank, curved ai; one end to form jhe hook and bent at its opposite endv to form a stop-lug having a cam-face.

In testi mony whereof We afx our signatures in presence of witnesses. .i
