Application filed March 22, 1926. Serial No. 96,378.

The main object of my invention is to provide a clasp for jewelry or the like which can be cheaply manufactured and sold reasonably, and which may be readily clasped and unclasped.

Another object of my invention is to provide a clasp consisting of an open-ended shell in which a spring-pressed element pro- Vided with a hook is housed, which element may be advanced against the action of the sprin so as to cause the hook to project out of the shellwhereby it may engage any desired object.

A further object of my invention is to provide interengaging means on the clasp for holding the slidable element in its ad vanced position against the action of the spring.

Further objects of my invention will be apparent from the following description considered in connection with the accompanying drawings, in which- Figure 1 is a perspective view of my improved clasp showing it employed as a link '5 for a wrist watch;

Figure 2 is a side sectional view of the clasp showing the hook in its normal or concealed position; and

Figure 3 is a view similar to Figure 2 but showing the hook in its advanced position.

In the constructional embodiment of my invention disclosed in the drawings, the numeral 1 designates a metal shell of substantially rectangular shape and curved to fit the wrist or arm, the two end sides of said shell being open. Within the shell 1 is the sliding element 2 which is composed of a single strip of metal provided with a hook 3 at one end and a loop at the other. This loop is preferably formed by bending the.

metal strip back at 4 to provide the portion 5 parallel to the sides of the shell and then bending the end of portion 5 as shown at 6.

The shell supports a crosspiece 7 which is in the form of a slender rod, and within the loop there is a spring 8, one end of which presses against the crosspiece and the other against the bend 1. The spring thus tends to urge the sliding element 2 into the 081- tion shown in Figure 2 with the hook 3 within the shell and bend 6 pressing against rod 7. By pushing against the sliding element at 4, the hook 3 may be caused to project out of the shell into the position shown in Figure 3 and is thus adapted to engage the loop 9 of a Watch 1.0 or similar device. When the sliding element is released, the spring urges it back into the position shown in Figure 2 and the Watch is thus securely held to the clasp. A loop 11 is secured to the exposed end 1 of the sliding element over which the hook of a similar clasp may be snapped or to which may be secured a Wrist band of any sort. p

In order that the hook may be held in its advanced or forward position, I provide interengaging means on the sliding element and shell, which in the embodiment illustrated takes the form of a lug 12 on the top of the shell 1, which may be formed in any suitable manner, and which is preferably formed by bending a piece of the metal of the shell up asshown. Secured to the slidlng element 2 is a hook or ring 13 which is adapted to engage over the lug 12 when the sliding element is advanced against the acticn of the spring 8. A slot 14 is provided in the shell 1 for the passage of the hook or ring. The interengagement of lug 12 and hook 13 holds the sliding element in the position shown in Figure 3 with the hook 3 projecting from the shell as shown in that figure. The hook and lug thus provide a simple means by which the sliding element may be held in its advanced position against the action of the spring 8. I

It is obvious that other interengaging means may be used for this purpose in lieu of the specific hook and lug 'construction disclosed and I have shown the lug and hook construction merely for the purpose of illustration.

Various modifications may be made in the embodiment of the invention described herein, and I desire to be limited only by the prior art and the scope of the appended claims.

What I claim is:

1. A clasp comprising an open-ended shell, an element slidable therein and adapted to be completely concealed thereby, one end of said element being provided with a hook and the other end with a loop, a cross piece secured to the shell and extending transversely through the loop, and a spring within the loop biasing said sliding element to the position wherein it is completely concealed by the shell.

2. A clasp comprising an open-ended shell,

an element slidalole therein and having a hook on one end, resilient means biasing said element to a position wherein the hook 5 is completely concealed by the shell, and means for holding the sliding element to the position in Which the hook projects from the shell against the action of the resilient means.

In testimony whereof, I have signed my 10 name to this specification this 17th day of March, 1926.

GUY NORMAN.
