J'FNVELRY COUIPLING.

Application filed March 12, 1921.

I0 all whom it may concern:

Be it known that we, F RED Prams and AUoUsr Frans, Sn, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Jewelry Couplings, of which the following is a specification.

The object of our present invention is the provision of a simple, inexpensive, safe and easily manipulated coupler, designed primarily, though not necessarily, to couple a bracelet to a wrist watch in such manner that there is no liability of casual disconnection and yet disconnection may be quickly and easily accomplished when desired.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part hereof Figure 1 is a plan view showing two of our novel couplers as associated with a wrist watch and a bracelet.

Figure 2 is an enlarged detail showing the inner side of a portion of the bracelet and the coupler and also showing a portion of the coupler in extended position.

Figure 3 is an enlarged detail longitudinal section on the line 33 of Figure 1.

Figure i is a cross section on the line 1 4: of Figure 2.

Figures 5, 6, 7 and 8 are views of parts that enter into the construction of the coupler as hereinafter explicitly described.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The wrist watch 1, and the bracelet 2 may be of the construction illustrated or of any other construction without afiecting our present invention which resides in the coupler.

Two of the couplers, indicated by 3 are employed in combination with the bracelet and the wrist watch in the specific illustrated embodiment of our invention. The said couplers are identical in construction and therefore a detailed description of the coupler shown in Figures 2 to 8 will sufiice to impart a definite understanding of both couplers.

Among other elements, the coupler, Figures 2 to 8, includes a casing member 4. The said casing memberd is formed of a Specification of Letters Patent.

Serial No. 451,899.

piece of metal such as shown in Figure 6, and in the present and preferred embodiment of the invention the said casing member is provided at its forward end with a hook 5, and guards 6 at opposite sides of the said hook. The casing member 4 con tains a core 9, provided at its rear end with an inturned flange 7 to form an abutment as hereinafter pointed out. In addition to the casing member 1-, and the core 9, the coupler includes a coiled spring 8, and a safety bolt 10. The safety bolt 10 is provided with a tongue 11 to project through the forward end of the casing member 4 and is also provided with lateral projections 12, Figure 5, to bring up against the forward end wall of the casing member. At its rear end the safety bolt is extended loosely through the rear end of the casing member 4-, and is designed to be hooked as indicated by 13 over a link 14 comprised in the illustrated bracelet 2. We would have it understood, however, that the rear end of the safety bolt 10 may be connected with a bracelet or other article to be coupled in any approved manner without involving departure from the scope of our claimed invention. At the point 15 the safety bolt 10 is provided with a rearwardly directed projection that is disposed in the forward end of the spring 8 so as to contribute toward the maintenance of the spring 8 and the safety bolt in proper working relation. The core 9 is of hollow form to receive the spring 8 and the safety bolt 10 as best shown in Figure 4, and is rabbeted as indicated by 16, to seat the inturned flanges 17 of the casing member a. The tongue 11 of the safety bolt 10 is preferably deflected as indicated by 18 in F igure 3 so as to bear against the inner side of the hook 5 and preclude casual disengagement of the said hook from the loop 19 of a wrist watch, for instance.

It will be readily understood from the foregoing and particularly by reference to Figure 3 that the spring 8 will normally hold the tongue 11 of the safety bolt against the inner side of the hook 5 for the purpose stated; and it will also be readily understood that when the casing member 4: is moved longitudinally outward with respect to the safety belt 10, or the safety bolt 10 is moved longitudinally inward with respect to the casing member 4, the tongue 11 of the bolt 10 and the hook 5 of the casing member 4 will be separated, whereupon the loop 19 of the wrist watch, for instance, may be readily disengaged from thehook 5. When, however, either of the elements 4: or 10 is released, the spring 8 will operate immediately to relatively arrange the safety bolt and the hook 5 of the casing member 4: as shown in Figure 3 for the purpose before stated.

In addition to the practical advantages hereinbefore ascribed to our novel coupler, it will be observed that the coupler is practically advantageous because of the facility with which its elements may be assembled, and also because of the complete enclosing of the spring 8 and the practically complete enclosing of the safety bolt 10 within the casing member f and its cooperating hollow core 9.

The casing member 4 and the hollow core 9 are adapted to be moved longitudinally as a unit or to remain at rest as a unit when the safety bolt 10 is retracted. Therefore we prefer to longitudinally taper the casing member 4 and the core 9 as best shown in Figure 2 so as to lessen the liability of either the member 4: or the core 9 moving longitudinally with respect to the other.

Having described our invention, what we claim and desire to secure by Letters-Patent, is

1. A coupler comprising a casing having an abutment at its rear end and a hook at its forward end, a safety bolt extending longitudinally through the casing and arranged to cooperate at its forward end with the hook of the casing and adapted at its rear end to be attached to an article to be coupled and having an abutment on its forward portion, and a coiled spring housed in the easing and interposed between the abutment thereof and the abutment of the safety bolt.

2. A coupler comprising a casing having an abutment at its rear end and a hook at its forward end, a safety bolt extending longitudinally through the casing and arranged to cooperate at its forward end with the hook of the casing and adapted at its rear end to be attached to an article to be coupled and having an abutment on its forward portion, and a coiled spring housed in the easing and interposed between the abutment thereof and the abutment of the safety bolt; the said casing comprising an exterior member and a hollow core arranged in and co- Operating with the exterior member and containing the safety boit and the spring.

3. A coupler comprising a casing having an abutment at its rear end and a hook at its forward end, a safety bolt extending longitudinally through the casing and arranged to cooperate at its forward end with the hook of the casing and adapted at its rear end to be attached to an article to be coupled and having an abutment on its forward portion, and a coiled spring housed in the casing and interposed between the abutment thereof and'the abutment of the safety bolt; the said casing comprising an exterior member and a hollow core arranged in and cooperating with the exterior member and containing the safety bolt and the spring, and the said exterior member and the core being longitudinally tapered.

4. A coupler comprising a member having a hook at one end, a safety bolt movable longitudinally with respect to the first-named member to cooperate at one end with the said hook and to have its opposite end connected with an article to be coupled, and a spring arranged in parallelism with the first and second-named members and interposed between abutments thereof to normally and yieldingly maintain the safety bolt incontact with thesaid hook to close the mouth of the latter.

In testimony whereof we aflix our signatures.
