T0 (1 whom it may concern:

Beit known that I, Frame 13. VVENDEL, a citizen of the United States ofAmerica, and a resident of Cranford, in'the county of Union and State of New Jersey, have 1nyentcd a new and Improved Necklace Clasp, (5.13. which the following is a full, clear, and

\ exact description. y

This invention pertains to jewelry clasps and refers more particularly to the body construction of clasps for necklaces or other similar articles of jewelry.

In the manufacture of clasps of this type, the front and rear plates of the body are of separate pieces of material which are soldered, riveted or otherwise joined together.

in spaced parallel relation, and it is obyious that the soldering, riveting, or other oining operation entails considerable labor and expense which necessarily adds to the cost of production. p

It is, therefore, an ob ectof the present invention to overcome soldering, riveting or other joining operations, by constructing the clasp body of a single stamping so that the same when bent will form the'front and rear plates without the necessity of employing any means of SECUI'GH'lBht other-than the inherent quality of the material to retain the shape into which it is bent.

More specifically the invention comprehends a clasp for necklaces or other similar articles of jewelry, consisting of a body member which includes front and rear plates and side and end prongs integral With the front plate and in which the said rear plate is formed of a pair of separate sections integral with the side prongs and adapted upon bending of the siderprongs to dispose the sections forming the rear plate in contiguous relation to each other and in spaced parallel relation to the front plates with the end prongs bent toward and abutting against the opposite ends of the nner surface of the rear plate to bridge the unction of the sections thereof.

As a still further object, the invention resides in a clasp of the character described, which is extremely simple in its construction, inexpensive to manufacture, and highly efficient in its purpose.

With the above recited and other objects in View, reference is had to the following specification and accompanying drawings in which there is exhibited one example or enibodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to be clearly understood that variations and modifications which properly fall within the scope of said claims may be resorted to when found expedient. f

In the drawings 7 Figure 1 is a facevieu of the clasp; I Fig. 2 is aplan view of the blank from which the same is formed; i Fig. 3 is a transverse sectional viewtaken approximately on the line 33 of Fig. 1;

Fig. 1 is a similar sectional View taken approximately on the line 4- l of Fig. 1.

Referring to the drawings by characters of reference, the clasp body includes a front plate 10 and a rear plate 11, which rear plate consists of longitudinally pivoted sections 12 and 13 formed integral with side prongs.

1-1: which prongs are formed integral'with the front plate 10. The front plate is further formed with end prongs 15 and the said device is initially stamped. from a single sheet of material in the blank form illustrated in Fig. 2. The side prongs-let are bent downumrdly at their juncture with the front plate 10 and the sections 12 and 1.3 are bent inwardly at their juncture with the side prongs i l to bring the free longitudinal edges 16 in contiguous or abutting relation as illustrated in Figs. 3 and 4:, so as to produce-the rear plate 11 which is disposed in spaced parallel relation to the front plate 10. The end prongs 15 are bent downwardly to ward and in abutting relation to the opposite ends of the inner surface of the roar plate 11 to bridge the juncture between the sections 12 and 13 thereof, the necklace at- From the foregoing it will thus be seen that a clasp body for necklaces or other similar articles of jewelry has been devised in which the necessity for soldering, riveting or other similar forms of connection, is eliminated, by constructing the body of a single sheet of material bent into position to form the device.

What is claimed is:

'1. A jewelry clasp body structure, comprising a front and a back plate, and integralconnecting prongs between said plates, the clasp being fashioned from a single blank in which one plate is formed entire and the other plate is formed of a pair of sections having meeting edges when the blank is bent to formthe finished clasp body.

2. In a clasp for neck-laces or other similar articles of jewelry, a clasp body including front and rear plates and side and end prongs integral with the front plate, the said rear plate formed of a pair of separate sections integral with the side prongs and adapted upon bending of the side prongs to dispose the sections forming the rear plate into integral relation with the front plate with the end prongs bent toward and abut-ting against the opposite sides of the inner surface of the rear plate to bridge the juncture of the sections 3. In a clasp for necklaces and other similar articles of jewelry, a clasp body member including a front and a rear plate and connecting prongs integral with said plates, the said rear plate formed of a pair of separate sections, and integral prongs bent from one of the plates into engagement with the other plate.

4. A jewelry clasp body structure, comprising a front and a back plate, and integral connecting prongs between said plates, the clasp being fashioned from a single blank in which one plate is formed entire and the other plate is formed of a pair of sections having meeting edges when the blank is bent to form the finished clasp body, said edges being on a median line of said sectional plate.

5. A clasp body structure cut, formed and bent from a single sheet of material to provide front and rear walls having integral connecting prongs, one of the plates being formed of a pair of sections, each section of which is joined to the other plate by the connecting prongs.

6, A clasp body structure cut, formed and bent from a single sheet of material to provide front and rear walls having intgeral connecting prongs, oneof the plates being formed of a pair of sections, each section of which is joined to the other plate by the connecting prongs, and other prongs formed integral with one of said plates and bent toward and abutting the inner surface of the opposite plate.
