IMPROVEMENT IN SNAP-HOOKS.

Specification forming part of Letters Patent N o.l 172,320, dated January 1B, 1876; application tiled November 2, 1875.

GAsE B.

new Improvement in Snap Hooks5 and Ido hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to

be a full, clear, and exa-ct description ot' the saine, and which said drawings constitute part ot' this specification, and represent, in

Figure l, top view; Fig. 2, side view 5 Fig. 3, longitudinal section 5 Fig. 4, transverse section.

This invention relates-to an improvement in what are known to the trade as snap-hooks, and particularly to that class in which the tongue moves longitudinally to and from the hook inl opening and closing; and it consists in constructing the body with a longitudinal recess with transverse longitudinal grooves, combined with a tongue, the shank of which sets into said recess and into said transverse grooves, to guide and support the tongue, and a spring arranged in said recess to operate the said tongue, as fully hereinafter described.

A is the body, terminating at one enclin the hook B, and at the other with a loop, C, or other convenient l`device for attaching the hook. The body is constructed with a longitudinal recess, D, upon its upper side, and with a longitudinal groove, d, in each side of said recess. These may be entirely through to the outside, as shown, or but partially, if desired. The tongue E is constructed to extend back and practically cover the said recess, and with a projection, a, extendiugdown into the said recess at the forward end, when the tongue is closed, as shown in Fig. 3. This projection ais constructed with a stud, f, upon each side, corresponding to the grooves d.

The spring F is arranged between the projection a and the rear end of the recess in the body, and beneath the rear extension ofthe tongue. At the rear a suitable guard, b, is arranged upon the body, to confine or guide the rear end of the tongueextension, and is also provided with a thu1nb-piece,e, as a couvenient means for moving it.

To set the tongue in position in the body,

the projection a is introduced with the tongue in a transverse position across the recess, and when down into its propersrelative position it is then turned into its longitudinal position, the studs entering the grooves d on the sides, thus securely attaching the tongue forward; then the guard b is closed over the rear end of the tongue-extension.

By this construction the hook and tongue are easily cast complete, and ready to be put together without the usual drilling .required for pivoted hooks.

I do not wish to be understood as claiming any of the parts, except in the combination as hereinafter, specified, especially as I am aware that a longitudinally-sliding tongue provided with a spring to return and hold it in a closed position is not new.

I claim- In a snap-hook, the body constructed with the longitudinal recess D and transversev grooves d, `the tongue constructed with the projection a, extending into said recess, and with the studs f, corresponding to the grooves d, the said tongue extended to the rear, so as to cover said recess, and.provided with a suitable guard, b, substantially as described.
