or MEEIDEN, CONNECTICUT, AssieNoE To HCBAET 1 C. HULL, CE sAME PLACE.

SNAP-HOOK.

SPECIFICATIONorming part of Letters Fatent No. 302,028, dated July 15,1884.

To all whom, it may concern:

Be it known that 1 ALEEET C. RAYMOND, residing Vat Meriden, in the county of New Haven and State of Connecticut, .have yinvented certain new and useful Improvements in Snap-Hooks; and I do declare the follow- 'ing to be a full, clear, `and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification. My invention relates to an improvement in snap-hooks, the object being to produce an article which shall beadapted to be both opened and closed without using the fingers, and which shall combine simplicity and cheap, ness of construction with durability and efciency in use.

, With these ends in view my invention consists in a'snap-hook provided with an adjust-` able fork arranged to be operated by direct pressure upon itsarms, and to be sustained in its open and closed adjustments solely by a Spring;

My invention further consists in certainde tails of construction and combinations ofparts,l as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a view inl perspective of a snap-hook constructed in accordance with my inyention. Fig. 2 is aview thereof in vertical longitudinal section. Fig. 3 is a similar View of one of the modified forms which the invention may assume, and Fig. fi is a view thereof in vertif cal transverse section through the lips of the shank and showing the fork in elevation.

As shown in Figs. l and 2 ofthe drawings, the vibrating forkA is provided with armsB and C, inclined to each other at something less than a right an gle,with an open slot,D, located between the said arms, and with a finger, E, situated near the end `of the arm C, as shown: The fork is fulcrumed lin the shank F of the hook G by its engagement through its openl slot D with a pin, H, located between two lips, I, formed upon the upper face of the shank of the hook. The fork is sustained in its engagement with the said. pin by means of a hat spring, J, which extends under it and engages as at I), on a curved line.

- its first position.

Application med March s, 1884. (No model.)

directly with the outer faces of its arms'. In 5o virtue also of the described engagement of ,the spring with the fork, the same is held in its open and closed positions thereby, andA without other aid. The said spring is located in an inclined recess, K, formed in the upper 5 5 p formed with an opening, M, into which the 6o` elbow N of the fork extends as the same is shifted in position. For the purpose of widening the opening between the shank and the loop 4O of the hook, the said loop is cut away,

in its open adjustment, the arm B of the fork is elevated, as, shown in Fig. 1 of the drawings. To engage a ring, link, strap, or other 'part of a harness with the hook, the part,

whatever it may be, is pressed directly against 7o the said arm B of the fork, with the effect of throwing the same over into the position in which it is shown in Fig. 2 of the drawings. In this position of the fork thepart engaged with the hook is prevented from being disengaged therefrom by the arm .C ofthe fork.

To release the part engaged with the hook, it is pressed directly lagainst the said arm C, and is released as the fork is thrown back into It will thus be seenA that 8o my improved hook is both opened and closed without using the iingersfand that it is oper'- ated by direct pressure upon the arms of the fork. It is to benotechalso, that as the spring passes from one arm of the fork to the other 8 5 larm thereof it .throws the same quickly into position, the pressure uponv the arms of the fork being required only at the beginning of the movement in either direction.

After the ring, link, strap, or other part of 9o the harness has been engaged with the hook, the-same may be locked, if desired, by throwing the fork back to its open` position with the handby means of the nger E, located upon the arm C of thefork, as has been described. In this position of the fork the part engaged with the hook can only be released therefrom by restoring theY fork to its closed Vhen the hook is 65A position, which is done by hand, as before, and then removing the part in the usual manner.

In the modification shown in Fig. 3 of the drawings the fork is provided with a pin, Q, which projects from its opposite faces. The projecting ends of the said pin have bearing in recesses R, formed in the inner faces of the lips of the shank, and extending from the opening therein to a point just within the upper edges of the lips, which are cast sufficiently apart to receive the pin, and then closed together to engage it. In other respects the modified hook is the same in construction as that shown in the other figures of the drawings. If desired, the pin II may be supplied to the lips instead of being cast with them. If desired also, the walls of the recess I may be upset for holding the spring J in place, instead of using a rivet for that purpose. I wouldv therefore have it understood that I do not limit myself to the exact construction shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

I am aware that a snap-hook provided with a fork actuated by a spring and supported in its closed position by engagement with the end of the hook is not new. I do not therefore claim, broadly, a snap-hook provided with a spring-actuated fork, but only my particular construction and arrangement of parts.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A snap-hook having an adjustable fork shaped substantially as shown, and a spring arranged to engage with the outer faces of the arms of the said fork, and shifting from one arm toY t-he other as the fork is adj usted, substantially as set forth.

2. A snap-hook having an adjustable fork shaped substantially as shown, and provided with an open slot through which it is engaged with a pin located in the shank of the hook, substantially as set forth.

3. A snap-hook having a vibrating fork one arm of which is provided with a linger, substantially as set forth.

4. A snap-hook having a spring-actuated fork, the shank of the hook, the fork, and the spring being constructed and arranged substantially as shown and described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
