W. E. KENNISON CLASP FOR NECKLACES AND THE LIKE Filed .Dec. 0. 1924 wax aw QZX-M front, a back having novel construction of a Patented Aug. 25, 1925.

I oLlL'sProR nnoKLAonsANn LIKE;

' "Application filed December 20,1924. L SeriaLNo;

To all whom it may concern:

Be it known that I, WILLIS EUGENE KEN- NISON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented anew and useful Improvement in Clasps for Necklaces and the like, of which the following is a specification. v

In a preferred up to date clasp for necklaces, the clasp consists of a body having a eight front connecting edge prongs each of which is secured to the front by solder, aring and a hook member which snaps onto the prongs. In this con struction all of the eight front connecting prongs are formed integral with the back.

The object of my invention is to produce such a clasp for necklaces and the like in which the front is secured to the back without the use of solder. I

A further object of my-invention is to re duce the cost of manufacturing such clasps to a'minimum cost.

My invention consists in'the peculiar and clasp in which end rongs on the front are used to connect the front to the back of'the clasp, said clasp having details of construction, as will be more fully set forth hereinafter and claimed.

Figure-1 is a front view of my improved clasp for necklaces and the like.

Figure 2 is an edge view of the clasp.

Figure 3 is a sectional view through the clasp taken on

line

3, 3, of Figure 2 and looking in the direction of the arrows a,a, towards the backof the clasp, and

Figure 4 is, a central longitudinal sectional view taken on

line

4, 4, of Figure 1 and showing the hookmember of the clasp in broken lines. o

All of the figures in the drawing are greatly enlarged to more clearly'show my invention..

In the drawing 5 indicates the body of the clasp and 6the hook member of the clasp; the construction of the body 5 of the clasp the hook member 6 As my invention lies in forms no part of my invention and is shown only to illustrate the complete clasp.

The body 5 of the clasp consists essentially of a front plate front and'back plates are of the same size and as shown approximately oval in form,

although'they maybe of any configuration to conform to any design of the clasp. As now constructed the 7 and a back plate 8. These integral plate having oppositely disposed rivet prongs.

back plate 8 has three ing a rivet end 12 which are riveted in the

rivet holes

10, 10, in the back plate 8, as

' shown in Figure 4.

These back

plate connecting prongs

11, 11,

are also bent slightly inward or towards each other so as to bring the rivet ends 12, into the

rivet holes

10, 10, where they are riveted .to the back, thereby securing the front to, theback without solder. a

The hook member 6 has spring arms 13,

"13, in which are notches 14, 14, and an e e 15 for securing the endzof a necklace to t e hook member, which is snapped. into the body member 6by, first hooking it over'the end back connecting prong 11 and then pushing it straight into the body until the notches'14,14, snap over the

adjacent prongs

9, 9, asshown in Figure 3. A ring 16, is alsosecured to the opposite back connecting end prong 11 to which the other end of the necklace is secured.

As heretofore constructed the back plate prongs are secured tothe'front plate by eight solderings; By the use of my improved construction the the back plate without the use of solder, thereby thus materially reducing'the cost of-manufacturing this form of a necklace clasp.

Having thus described my invention I claim as new I 1. A clasp for necklaces andthe like, said clasp consisting principally of abody member comprising aback and a front plate,-

having rivet holes and a pluthe ends of which and the front plate the back plate rality of edge prongs engage the front plate,

having edge prongs riveted in the rivetv for the purpose as holes in the back plate, described.

front plateis secured to I eliminating eight solderings and 2. A clasp for necklaces andthe like, said clasp consisting principally of a body member comprising a back plate having oppositely disposed rivet holes and a plurality of oppositely disposed edge prongs formed with the back plate and a front formed integral with the front plate and riveted in the rivet holes of the back plate the ends of the. prongs on the back plate contacting with the inner face of the front plate.

3. In a clasp having a body member, a snap member and a ring member for the purpose described, said body member consisting of a front plate and a back plate, the back plate having end rivet holes and a plurality of oppositely disposed edge prongs the ends of which engage with and the front plate having end rivet prongs, the

ends of which are riveted in the rivet holes in the back plate, thereby spacing the front plate from the back plate and securing the front plate to the back plate without solder. In testimony whereof, I have signed my name to this specification.
