SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 437,991, dated October 7, 1890.

Application filed May 19, 1890. Serial No. 352,366- (No model.)

To all whom it may concern:

Be it'known that I, GEORGE M. HUBBARD, of New Haven, in the county of New Haven and State of Connecticut, have invented new Improvements in Snap-Hooks; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure 1, a top view of the hook complete; Fig. 2, a side view of the same; Fig. 3, a longitudinal central section on line 00 at of Fig. 1; Fig. 4, a face View of the loop detached; Fig. 5, an end View of the same; Fig. 6, the blank from which the body is formed; Fig. '7, the tongue detached; Figs. 8, 9, and 10, modifications.

This invention relates to an improvement in that class of snap-hooks in which the springtongue is arranged so as to be depressed inward from the nose of the hook in opening, and particularly to that class of such hooks which are made from sheet metal.

In the usual construction of snap-hooks in which the body of the hook is made from sheet metal the eye or loop for the attachment of j the strap is usually hinged or swiveled to the body, except in the smaller class of snaps, in which a short loop only is desirable. In such case the loop or eye is made integral with the body of the hook; but this integral character of the loop is impracticable where a loop of considerable length is required, impracticable because of unavoidable waste of metal and lack of the requisite strength.

The object of my invention is to construct a sheet-metal hook with a strong rigid loop; and it consists in the construction as hereinafter described, and particularly recited in the claims.

A represents the bodyof thehook, made from sheet metal, one end of which is turned up to form the nose B of the hook, as in the usual construction.

C represents the loop. It is preferably made from cast metal. The loop is shown detached in Figs. 4 and 5. It is composed of two bars a b, closed at their ends, and on one of the bars, as a, a projecting lug (Z is formed. This lug corresponds substantially to the width of the base or body of the hook.

In the best construction of the body it is made from a blank of sheet metal, as seen in Fig. 6, the central portion 6 forming the body proper, with projections f on each side, which are turned up to form side flanges, as seen in Figs. 1 and 2, so as to leave a space between them. The projection d on the loop corresponds to the width of the space between the two flanges or sides f f of the body, and so as to be set therein,as seen in Figs. 1 and 3. In the best construction the projection 61 is constructed with a tubular stud g on its upper side, the under side being adapted to lie flat upon the body of the hook. structed with a hole It, corresponding to the opening through the tubular stud g, this tubular stud opening through the projection cl.

D represents the tongue, which is also made from sheet metal and of the requisite length. At one end a hole '6 is made corresponding to the tubular stud g and so as to set on over that stud, as seen in Fig. 3, the length of the stud being somewhat greater than the thickness of the tongue. The length of the tongue is such that the opposite end may stand beneath the nose B of the hook, as seen in Figs. 2 and 3.

E represents the spring, which is a flat feather-spring, having a hole at one end corresponding to the hole It through the body.

In assembling the parts the spring is first set into the body with its hole registering with the hole hin the body. Then theloop is set in place to bring the stud g over the said hole 72, in the body and the hole in the spring. Then the tongueis seton over the stud g, andthrough the stud, the spring, and the body a headed rivet or screw F is introduced and secured to the body, so as to firmly unite the loop to the body, the head being of larger diameter than the stud, so as to project over the tongue around the stud. The length of the stud is somewhat greater than the thickness of the tongue, so as to allow free play of the tongue, the tongue in width corresponding substantially to the width between the two sides f f, as seen in Fig. 1. Thus assembled and secured, the loop is rigid as the body itself, and sub- Ice The body is con-' stantially as if made an-integral part thereof. The spring is held in place by the same rivet which unites the loop and body, and the tongue is hung upon the stud, so as to permit it to swing thereon to open and close the hook, the spring serving to hold the tongue in its closed position.

This construction is simple, and yet produces a hook of neat and finished appearance, and strong and durable for all purposes for which hooks of this character are desirable.

The loop 0, as seen in Figs. 9 and 10, is constructed with the same projection d as in the first illustration.

In assembling the parts the flange 7c of the body turns up within the loop, as seen in Fig. 11, and the tongue and spring are applied, as before described. The flange in, bearing against the inside of the top, prevents any lateral swinging movement of the loop, so that but a single rivet is necessary. This rivet may be as in the first illustration, or the projection (1 may be cast with a rivet Z upon one side and a similar rivet m upon the reverse side to extend through the holes in the respective parts, as seen in Fig. 8. In this case there is the same rigidloop as in the first illustration, the loop being made separate from the body but firmly united thereto. The spring may be omitted by making the sheet-metaltongue a spring itself, so that when depressed it will automatically return under its own elasticity when the force is removed.

I claim- 1. A snap-hook composed of a sheet-metal 5 body having one end turned up to form the hook and constructed with flanges projecting from the body upon opposite sides and turned up at substantially right angles to the body, forming a longitudinal space between the said flanges, combined with a loop made separate from said body, constructed with a projection on one of the bars of the loop adapted to set between said sides of the body at the end opposite the hook, the loop rigidly secured to said body through said projection, with a spring-tongue arranged on said projection and between the said sides of the body, substantially as described.

2. A snap-hook composed of a sheet-metal body A, terminating at one end in the hook B, the body constructed with side flanges ff, combined with a loop 0, composed of two connected parallel bars a b, a projection d from one of said bars corresponding inwidth substantially to the width between the two sides of the body and adapted to set into the body between the said two sides at the end opposite the hook the said projection constructed with a tubular stud g, and a sheet-metal tongue D, loosely hung upon said stud, with a spring between said tongue and body, the said loop rigidly secured to the said body through-the said stud, substantially as described.
