P. J. COFFEY CLASP Filed April 25 1924 Patented Mar. 9, 1926.

UNITED STATES PATRICK J'. COFFEY, OF CI-IA'II-IAM, NEW JERSEY.

CLASP.

Application filed April 23, 1924. Serial No. 708,385.

which the following is a specification, ref-' erence being had to the accompanying drawings, which form a part of the same.

The principal object of my invention is to provide a clasp which is particularly adaptable for securing articles of adornment and use to. the person, and readily rovides for the release of the same when it 1s desired to remove them.

Other objects of my invention will be apparent from the following specification and the accompanying drawings in which I have shown my clasp in use with a watch and bracelet for the wrist adapted to be used therewith, and in which drawings-- Fig. 1 is a face view of a wrist watch and bracelet embodying the use of my clasp;

Fig. 2 is an end view of the same;

Fig. 3 is a side view along the line 22 of Fi 1 ih fa is a view looking at the same from the top along the line 4.4 of Fig. 2;

Fig. 5 is a bracelet with a pair of my improved clasps connected thereto.

Referring now in detail to the drawings,-

7 represents a wrist watch having the usual loops 8 in which is hooked my clasp 9.

This clasp embodies a hook 10 and has mounted within the same the spring lip '11 in such manner that the outward tension of the spring will be arrested by the end of the hook as shown. The clasp is shown in wearing position in Fig. 2, in which the loop 8 is disposed behind the spring lip 11. Swivelly mounted in the clasp 9 is a cam 12, secured to the lever 13 and adapted to move therewith. The purpose of this cam and lever is to depress the spring lip 11 so as to clear the loop of the watch or other article with which said clasp is connected and permit the hook of the clasp to be readily removed therefrom.

In Fig. 5, I have shown In clasp connected with a wrist watch brace et. In order to attach the watch thereto the hook of the clasp is fitted over the loop of the watch, the spring lip 11 beingdepressed by said loop, and when the same has passed the end of the hook of the clasp, the clasp is drawn in a direction away from the loop which clears the spring lip 11 and brings the spring in intimate contact with the end of the hook 10 so that the loop is then disposed behind the said spring lip. The watch is then applied to the wrist in the usual way and the clasp at the opposite end of the bracelet is similarly connected with the opposite loop of the watch. When it is desired to remove the watch, the lever 1.3 is moved in an arcuatc direction so as to bring its integral cam 12 in contact with the spring lip 11 and move the spring lip upward so as to clear the loop and permit the watch to be unhooked therefrom.

I have shown and described what I believe to be the best embodiment of my invention. I do not wish to be confined in patent protection to the embodiment shown, or to be limited in its application to a watch, but what I desire to cover by Letters Patent is set forth in the appended claims.

Claims- 1. In a clasp, a. hook, a spring lip nor.- mally in contact with the free end of said hook, and a lever for depressing the spring lip, and maintaining the same in depressed condition. I

2. In a clasp, a hook,a spring lip normally in contact with the free end of said hook, a cam adapted to act upon and depress said spring lip and maintain the same in depressed condition, and lever means integrally connected to said cam for operating the same.

In a clasp, a hook, a spring lip normally in contact with the, free end of said hook, a cam swivelly mounted in said clasp, and adapted to arcuate movement to act upon and depress said spring lip and main tain the same in depressed condition, and lever means integrally connected to said cam to operate the same. I

4:. In a clasp, a hook, a spring lip normally in contact with the free end of said hook, a cam swivelly mounted in said clasp, said cam being adapted to arcuate movement inwardly to act upon and depress said spring lip and maintain the same in depressed condition.
