SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 234,716, dated November 23, 1880,

Application filed March 11, 1880.

To all whom it may concern Be it known that I, ARTHUR H. MoULToN, J r., of Akron, in the county of Erie and State of New York, have made certain Improvements in Snap-Hooks, of which the following is a specification.

This invention relates to snap-hooks for harness and other purposes, the object of the invention being to get a hook that can be operated without touching the spring with the hands-that is, by which the ring, loop, staple, or other device can be caught in the hook by merely pressing it against the spring, and also unclasp it by a mere pull or twist of the ring; and the invention consists in the con struction of the device, as hereinafter specified.

In the drawings, Figure 1 is a vertical elevation of the snap-hook, showing a section of a ring in the hook. Fig. 2 is a perspective view of the device, showing the parts complete.

A represents the main part, being a frame made of a single piece of malleable iron or other suitable metal, with a loop or ring, a, at the end, in which the strap, &c., of a harness or chain is buckled or otherwise fastened. From this pointit is bent down at a slight slant for a space of about two and one-half inches, (more or less,) and then bent up sharply and over into a hook, I).

For lightness the main part A is made open into a frame and unites in the hooking-point b. This extreme point is notbent inward or downward, but projects forward over and in a line with the main part A, as shown. At the base of the loop a is securely fastened, at 0, a metal tongue or snap-spring, d, which projects forward and slightly upward until it meets the point of the hook I), when it is bent down at a slant, as shown at d, with the end (1 projecting into or through the part A, either in a slot therefor or an opening in the frame (Model) A. This spring is made sufficiently stifi to always retain its position against the end of the hook at a, and leaving a space, 0, between the inside of the hook and the end 01 of the spring to hold the ring B or other device therein, and at the same time prevent any back working of the ring, except when desired to release it from the snap-hook.

It is operated as follows: The snap-hook is' not necessarily handled at all. The ring is held in the hand and pressed-either downright on the spring cl, or else against the side or edge of the spring at d, which forces the spring down sufliciently to catch the ring in the hook, the snap springing hack instantaneously. To withdraw it the ring is given a slight twist against the spring and pulled a little, which releases it at once.

Of course the spring can be operated, it on the end of a hitching strap or chain, by pressing down the spring with the thumb; but it is intended to operate without the touching of the spring at all. Its simplicity and cheapness are apparent, it cannot easily be broken, and the spring has no partor parts to become lost, disarranged, or destroyed, and its working is always sure and safe.

I claim- In a snap-hook, the combination of the frame A, having an opening or slot in its back, with the spring d, bent to pass through said slot and bear against the point of the frame, where by a space, 6, is provided between the spring and the curved top of the frame, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
