WIRE SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 400,256, dated March 26, 1889.

Application filed January 9, 1889.

To all whom it may concern:

Be it known that I, SAMUEL P. SCOTT, of I-Iillsborough, in the county of Highland and State of Ohio, have invented certain new and useful Improvements in Snap-Hooks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 is a View of a wire blank for forming my improved snap-hook. Fig. 2 is a side view of a snap-hook formed therefrom. Fig. 3 is a plan view of said hook. Fig. at is a side View of a modified form of hook; Fig. 5, a side view of the same. Figs. 6 and 7 are similar views of a second modification.

This invention is an improvement in wire snap-hooks of the kind formed of a single length of wire, and its object is to improve the construction of the same, so that the hook will be stronger, may be more conveniently attached or hooked to an object, and will not be liable to pull open and to these ends the invention consists in the peculiar and novel construction of the hooks, as hereinafter clearly set forth and claimed.

In the accompanying drawings, A represents a wire blank, which is formed of a single length of Wire bent upon itself, as shown in Figs. 1 to 5, and at the end of said blank, where the wire bends upon itself, is formed a loop or eye, B, while at the other end of the blank the ends of the wire are laid close together and soldered or otherwise securely fast- This blank A is bent near the center of its length into a small oval loop, O, the end portions of the wire meeting near the center and at one side of the loop and there turning out at right angles into arms D and E, arm D, which is the end having eye B, being shorter than arm E and forming the tongue of the completed hook.

The two arms extend forward side by side and are entwisted at a, near loop 0, to close said loop, and also to prevent the arms from separating. At least one full twist is given to said arms, and tongue D is bent so that eye B will lie in a horizontal plane with loop 0, as shown. Arm E lies vertically below the tongue and diverges therefrom, owing to the twist of Serial No. 295.818. (N0 model.)

the blank; but it projects beyond eye B and is bent upward and over said eye in a hook, F. The end of said hook is also the extremity of the blank, and is bent downward and inward at a sharp angle, forming a tooth, G, which engages eye B, as shown, and therewith forms the catch proper. Tongue D can be depressed to cause eye B to disengage too h G, and thus permit the hook to be engaged on a ring or the natural resiliency of the wire causes the tongue to spring outward, and eye B again engages tooth G. If the object to which the hook is attached be forced upward against tooth G, it cannot force eye B out of engagement therewith, and if violent strain is exerted on hook F tooth G, catching in eye B, transfers the strain to arm D and the hook cannot be straightened out, and, if effected at all, its curvature will be more increased, and consequently the bite of the tooth in the eye will be increased, as the tongue D will have less movement, and more power will be required to disengage the tooth and eye. The hook is attached to a strap or where desired by means of loop 0; but the strain on said loop can have no effect on the eye B and tooth G, owing to the twisting of the wires at c.

Preferably I entwist the wire of blank A before forming the hook thereof, and by so doing obtain the hook shown in Figs. 2 and 3, which I deem the strongest and most durable, since the wires, being entwisted throughout except the tongue, it is impossible for one wire of the blank to be subjected to more strain than the other. Figs. 4 and 5 show the hook made from blank A without previous entwisting thereof.

The snap-hook illustrated in Figs. 6 and 7 differs from the others in that it is formed principally with but one thickness of wire. The arm D is, however, double, and has eye B formed as before described; but loop O,hook F, and tooth G are made of a single length of wire. The return portion of the wire forming the double thickness of tongue D in this modification is twisted around the contiguous wires of arms D and E at (1. Instead of entwisting these arms, as before described, twist d binds the wires properly together and closes the loop, so that practically the several snaphooks are alike, as they each contain similar portion of a harness; but as soon as released and inwardly inclined tooth, G, adapted to engage said eye, all formed of a continuous wire, substantially in the manner and for the r 5 purpose specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.
