Leners Patent No. 68,223, dazed segue 27, 1867.

IMPEOVED SNAP-1100K.

T ALL WHOM IT MAY CONCERN -Be it known that I, CHARLES MILLER, of the city of Buffalo, county of Erie, and State of New York, (assignor to myself, Thomas W, Toye, and Edward L. Cook,) have invented a new and improved Snap-Hook; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specication, in whichi l Figure I is a perspective view of my improved snap-hook.

Figure 'II is a longitudinulsection; and i Figure III is a back view of the same.

The nature of this invention consists, lfirst, in extending the tongue of a snap-hook downwardly across the ringer loop of the same, so as to form, in conjunction with such loop or ring, a buckle, in a manner that the action of the strap to which the buckle is attached causes the tongue of the hook to remain closed without the aid of a spring or other device now used for the same purpose; second, in attaching or hinging the tongue of a snap-hook to the shank or main body by means of a pin projecting from the. tongue and a fulcrum formed onl the sha-nk, the said pin being b ent around the fulcrum on the back oflthe snap-hook.

Letters of like name and kind refer to like parts in each of the i'gures.

My improved snap-hook is composed of two parts, both of which are cast of malleable iron, or other material adapted to the manufacture of the article.

A represents the shank or main part of my improved snap-hook, the upper end of which is curved, and forms the hook, as represented ,at A. The loop or ring ofthe snap-hook is shown at B, and is shaped in' a common manner. Ajournal-bearing is cast on to the main part or shank A, below the point where it branches out to form the loop. This bearing is shown at a2, Fig. II, and serves as a fulcrum for the tongue of the snaphook, which is hinged thereon in the manner hereinafter described. C represents the tongue, the' upper part of which is shaped so as 'to open or close the hook A in a common manner. A pin, c', is cast on to this tongue, as shown by red dotted lines inFig. II, by means of which it is hinged to the bearing a2 in the following manner: The pin c' is passed through the opening formed between the shank A and cross-brace a2, until lthe tongue is in its proper position. By a single blow of a hammer the pin is bent` at the back of the shank and i around the bearing a2, so as to surround the said bearing, thereby hinging and attaching the tongue permanently to the shank of the snap-hook. The tongue is extended below its fulcrum, asshown at D, the said extension forming, in conjunction with the loop B, albuckle, to which the strap E is connected. The tongue D is passed through a hole in the strap, in a common manner, and the free end of the strap is bent and confined within a loop upon the strap E, as shown at E. The lower end of the tongue is provided with a hook, al', which clasps the ioop B. The action and tension of the strap E cause the hook d tol remain in contact with the loop B, no matter in which direction the strap is turned, and hence the tongue C firmly closes the snap-hook without the aid, of a spring or other-device now used for the purpose.

This snaphook has many qualities which recommend it to the trade, the principal one of which is its great cheapness of construction, and its formation of a buckle, and completeness of action. There are no rivets, no springs, no holes to be drilled; all such expensive parts can be dispensed with in the manufacture of this article. There are only two parts, and these are joined together by a single blow of the hammer.

What I claim as my invention, and desire to secure by Letters Patent, isp `1. The tongue C, extended below its fulcrum-bearing to form the buckle-tongue D, in combination with; the loop B, thereby forming a snap-hook and buckle, substantially as described.

2. Hinging the tongue of a snap-hook to the shank thereof by means of the pin c and the brace or bearing a2, both constructed and combined substantially as herein set forth.
