Letters Patent No. 81,026, dated August 11, 1868.

IMPROVED SNAP-HOOK.

' TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM E. SPARKS, of New Haven, in the county of New Haven, and State of Connecticut, have invented a new Improvement in-Snap-Hooks; and I do hereby declare the following, when taken in connection with theaccompanying 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 YIlya top view, and in s Figure 2 a side view, a portion being broken away to more clearly illustrate the construction. v

This invention relates toan improvement in the artieleot' manufacture commonly known as snap-hooks, the object being to construct a hook which cannot, by any possibility, b'e Vaccidentally unsnapped, and consists in the arrangement .of a divided tongue, one part of the tongue openingdownward inte the hook, the other part outward from the hook, so that, by opening the outer part, the hook may be readily' clasped upon the thing to which it is desired 'to attach it, the under part yielding for the purpose, and when so attached, the said under .partfsprings backiagaist the' hook, so that it cannot be detached by any pressure outward, and the outer kpart,-

released, falls upon the outer end of the hook, and the under part of the tongue, so that no pressure from the outside upon the tongue can effectV its release, the two parts ofthe tongue acting in conjunction, to prevent the unsnappi'ng ofthe hook.

In order to the clear understanding of my invention, I will fully describe the same as illustrated in the accompanying drawings.

A is the hook, provided, in the usual manner, with an eye, `B, or other means of attachment.

a is the lower part, and d the upper of the snap, pivoted upon a common centre at f, ou the body of the hook, as seen in fig. 2. 'lhe two parts of the tongue extend back of the pivot, and between the two ends so extended back, a spring, b, of any convenient construction, is placed, the tenden'cyof which is to force the two parts ofthe tongue together, as denoted in fig. 2, the upper side ofthe end of the hook forming a bearing for the upper part CZ of thc tongue, and the under side ofthe end of thehook, in similar manner, forms a vbearing for the under part of the` tongue.

To attach the hook, raise the part cl by means of a projection, h, or other device, to the position denoted in blue, iig. 2, then the part a is in the position of the tongue of an ordinary snap-hook, and may be attached/in like manner, passing the hookeon to the thing to which it is to be attached, so that the said thing will pass under the upper part d of the tongue; then it will naturally depress the under part a, and enter the hook, inv like man'- ner as in common snap-hooks; the upper part then released, prevents any outward pressure being brought to bear upon the under part, however the hook may be twisted from the thing to which it is attached, and therefore cannot, by any possibility, he accidentally detached. l

To release the hook, depressthelower part ofthe tongue by means of the projection Zthercon, (as seen in red, iig. 2,) extending through the under side of the hook, or by other means, so that the 'thing to which the hook is attached may pass between the/upper and lower part, then the hook may be easily drawn from the said thing, the upper part yielding fr the purpose.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, isy The arrangement of a divided tongue in two parts, a. and d, pivoted so that cach may turn independent of the other, and so that oneropens outward, and the other inward, each bearing upon the end of the hook A, and provided, respectively, with projections k and Z, or other equivalent means, for operating substantially in the manner and for the purpose herein set forth.
