3,077,689 CLASP FUR A NECKLACE R iiRAQELET Murray Siiverman, New York, NRC, assignor to Eisenberg Jewelry, inc, Chicago, iii, a corporation of Iiiinois Filed Apr. 26, 196i), Ser. No. 24,715 1 Ciairn. ({Jl. 63-3) This invention relates to fastening devices in general, and particularly to a fastening device for securing the links of a necklace, bracelet, or the like, to one another.

An important object of the invention is to provide a device of this character which securely fastens and holds the links of a necklace, bracelet, or the like, to each other without danger of accidental displacement, while permitting ready and easy assembly and disassembly of the parts.

Another object of the invention is to provide a fastening device of this character and having the foregoing advantages and capacities, and which is of simple and durable construction, reliable in operation and adapted to be manufactured at a comparatively slight cost from materials and by means of facilities ordinarily available.

Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter more fully described, reference being had to the accompanying drawing forming part of this specification, and in which:

FIG. 1 is a fragmentary view, in side elevation, showingthe invention as used with a necklace;

FIG. 2 is a fragmentary top view of the device as seen in the direction of line 2-2 of FIG. 1;

FIG. 3 is a top view of an enlarged detail of the parts of a modified form of the device as used with a bracelet;

FIG. 4 is a view, partially in section and on a larger scale, of a portion of FIG. 2;

FIG. 5 is an enlarged detail of a modified form of a component of the device.

Referring now to the drawing in detail: Numerals 7 and 9 indicate the terminal elements or end portions of a necklace, which are to be secured to one another. In the illustrated embodiment, the end portions as well as the rest of the necklace may be made up of concave mountings, such as 11, 11a, 11b, in which are set stones, such as 13, 13a and 13b. Secured with one end to the bottom of mounting 11, by soldering, is a laterally extending flat metal strip 15, the other end of which is secured to the bottom end of a vertically extending pin 17. To the upper end of pin 17 there is secured the underside of a mounting 19. A metal strip is secured to the underside of mounting 19 and the upper edge of mounting 11. Strip 15 and the underside of mounting 19, thus serve as rigid supports for pin 17. It should, of course be understood that any other form of support for pin 17 can be used.

Secured to the bottom face of mounting 11a is a hook member 21 of the clasp shown, together with pin 17, in enlarged plan view in FIG. 4. The hook member 21 is made of a resilient metal or metal alloy and is formed with a rounded recess 23, which is of a width to permit the passage of pin 17, and a semi-circular hook portion .25, terminating in an enlarged end 27. Hook 25 thus forms a circular recess 26, into which may be received pin 17 which is of substantially the same diameter as recess 26. The book is further formed with an inwardly directed projection 29, which divides recess 26 from recess 23. In use, the two terminal elements or end portions are secured to one another by sliding pin 17 into recess 23 from position A into position B. The ends of the necklace are next pulled in opposite direction and due to the lateral force applied thereto, displace the re silient portion 27 of hook member 21, While passing over the projection 29, to permit the pin to enter recess 26 and assume the position C. The enlarged end 27 of the hook member now returns to its original position, thus preventing the pin 17 from lateral displacement trom position C, because the distance between enlarged end 27 and projection 2% is smaller than the thickness of the pm.

When it is desired to disengage or unlock the necklace ends or terminal portions, these are pushed or displaced laterally towards one another, thus causing pin 17 to displace resilient end 27 of the hook member and move into position B in recess 23 from which it may be readily pulled out by a sideward movement of pin 17.

FIG. 3 illustrates the device of the invention as applied to a bracelet which is usually made up of a plurality of rows of mountings or ornaments linked together. In such an application, there may be employed two spaced pins 35 and 37 secured to strips 31 and 33 and to mountings 30 and 32, of one terminal portion of the bracelet, in the manner previously described in connection with the necklace of FIGS. 1 and 2. A pair of hook members 41 and 43 may then be provided, integral with a strip 39, which is soldered to the other terminal portion of the bracelet. The bracelet ends are secured or disengaged in the manner previously described in connection with the necklace.

In a modified form of the device, as shown in FIG. 5, both the inwardly extending projection 51 and end 53 of the hook member have a sharp pointed, instead of a rounded shape. Otherwise, the operation of the device according to this figure is in all respects the same as above described.

Having thus described the inventiion, what I claim as new and desire to secure by Letters Patent is:

In combination, a bracelet consisting of a plurality of attached mountings whose bottom portions are disposed in the same plane, a first end mounting secured to an adjacent mounting with its bottom portion spaced above said plane, a plate element secured to the bottom of said adjacent mounting and extending below the bottom portion of the first end mounting and spaced from said end mounting, a cylindrical element connecting the bottom of said end mounting and said plate element, said cylindrical element forming the eye of an eye-and-hook device in combination with a planar hook member of resilient material adapted to receive said cylindrical element, said hook member having an enlarged, rounded, free end portion and another end portion adapted to be secured to a second end mounting and formed with a projection directed inwardly of the hook and defining With said enlarged free end portion a mouth narrower than the diameter of said cylindrical element, said mouth restricting the detachment of said cylindrical element, said hook member being adapted to have the cylindrical element attached and detached from the hook by yielding enlargement of the mouth as the cylindrical element is moved past said mouth.
