SNAP-HOOK.

Specification of Letters Patent. Patented Aug. 23, 1910.

Application filed January 9, 1908. Serial No. 409,986.

To all whom 'it 'may concern:

Be it known that I, FRANK E. SGHARTOW, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in 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.

My invention relates to snap hooks, and especially to chain snaps.

The object of the invention is to provide a device of this character which will be eiiicient in operation, cheap to manufacture, quick to apply and disconnect in practice, and self-locking.

l/Vith this object in view, the invent-ion consists of certain novel features of construction, combination and arrangement of parts as will be described hereinafter and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of the device with several links of the chain attached to one end, a ring secured to the other; Fig. 2 is a top plan view of the device; and Fig. 3 is a longitudinal sectional view.

Referring more especially to the drawing, 1 represents a body which is provided at one end with a hook, 2, having a recessed nose, 3, adapted to be engaged by the tongue, et, as is usual. The rear end of the body 1 is provided with one member, 5, of a split ring, which has raised from one side thereof a wedge-shaped lug, 6, adapted to enter the aperture formed in the opposite member, 7, of the split ring which is formed integrally with the tongue. The tongue is also provided with a wedge-shaped lug, 8, opposite to its apertured side to enter the aperture on the member, 5, so that the lug 6 completes tlie'ring of the member 7, and the lug S completes the ring of the member 5. Suitable ears, 9 and lO, extend up from the opposite sides of the body 1, adjacent its longitudinal center, and are adapted to be bent over a pintle, 11, which is formed integrally upon the tongue.

The body l is notched at 12 and the tongue is apertured at 13 and provided with a shoulder, 14, within an aperture to receive a leaf spring, 15, which bears upon the forward underneath edge of the opening, and normally holds the members, 5 and 7 together.

As shown in Fig. 1, when the chain link, 16, is applied to the split ring composed of the members, 5 and 7 it securely locks the two members together and prevents the tongue t from being depressed; and to operate the tongue, the link has to be slipped around so as to aline with either one of the lugs, 6 or 8, so that the opposite split ring member may be moved, or the link may be tilted so as to have its vertical aXis transverse to the eye and the members released in this manner.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is:

1. In a snap hook, a body portion having a hook member at each end, said hook members lying in different planes, and a tongue member pivotally connected to the body portion at an intermediate point, and having one 'of its arms forming a tongue which cooperates with one of the hooks of the body portion, and its other arm constituting a hook member which cooperates with the other hook member of the body portion to form an eye, said coperating hook members being interitted, together withl a spring arranged .to act upon the tongue to close both hook members; substantially as described.

2. In a snap hook, a body member having a hook portion at each end, said portions lying in planes perpendicular to each other, one of said hook members being cut away vertically to form the entrance of the hook and also cut away upon its upper surface, and a tongue member pivotally connected to the body member at an intermediate point, and having one of its arms constituting a tongue proper, and its other arm forming a hook member of complementary form to the corresponding hook member of the body, said hook members together forming a vertically-separable eye, together with a spring interposed between said members and acting to hold them in closed relation; substantially as described.

3. A snap hook having its hook and tongue members pivotally connected and eX- tended rearwardly of the connecting pivot,

vteriitiiing projection and recess guarding their openings; substantially as described.

5. ,ifi snap-hook having its hook and tongue 1r-.embers pivotally Connected and eX- tendeL rearwardly of such connection, the extensions being each formed with a hook pei-tiem and said hook portions being halved together to form a separable eye, t0-

gether With a spring for holding both the hook and eye closed; substantially as described.

G. n a device of the class described, the combination with a body having a hook ab one end, a tongue pivoted on the body adapted to Close the hook, a resilient member for holding the tongue in Closed position against the nose of the hook, split ring members carried by the body and the tongue, and lugs on each member adapted to cooperate with the opposite member to completely close each member.

In testimony whereof I have here-unto set my hand in presence of tivo subscribing Wit-- nesses.
