11102, and Samuel Friedman, 556 Ave. Z., Brooklyn,

Filed Mar. 26, 1964, Ser. No. 355,123 8 Claims. (Cl. 63-1) This invention relates to the art of jewelry clasps and more particularly concerns a clasp for adjusting the length of a necklace, string of beads, chains, or the like.

According to the invention there is provided a clasp including a channel-shaped base member. At each end of the base member is pivotally mounted an arcuate catch member. Fixed at its center inside the base member is a leaf spring having movable opposite ends engaging ends of the catch members for holding them in both closed and open positions. The catch members when closed define two yokes for engaging opposite ends of a string of beads, pearls and the like. Projections are provided on the catch members to facilitate opening and closing them with respect to the base of the clasp. Suitable jewel cr-owns or jewel settings may be mounted on the base. Alternatively a jewel crown or setting may be mounted on one of the catch members. The jewel setting will then help hold the other catch member closed. Tubular supports may be mounted on the catch members for receiving a pin so that the clasp can be engaged on a garment or in a persons hair. The pin may serve as a locking means for holding the catch members closed. A pin receiving tube can be attached to the base.

It is therefore one object of the invention to provide a clasp bar including a channel-shaped base member with a centrally bent or bowed leaf spring held therein at its center, opposite ends of the leaf spring being movable, and catch members pivotally attached to opposite ends of the base member for defining two yokes with the base member when the catch members are closed.

Another object of the invention is to provide a clasp as described, wherein either one of the catch members may be opened while the other catch member remains closed with the base member, under spring tension.

A further object is to provide a clasp as described wherein a jewel setting may be mounted on one of the catch members or base member, thejewel setting helping to hold one of the catch members closed when mounted on the other catch member.

Still another object is to provide a clasp as described with a tubular member mounted on the catch members or base member for engaging a pin to attach the clasp to a garment or a persons hair.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a side elevational view of one clasp embodying the invention, with one catch member open and the other catch member closed.

FIG. 5 is an exploded perspective view of parts of the clasp of FIGS. l4.

FIG. 6 is a perspective view of the clasp with catch members open and parts of an associated string of beads. FIG. 7 is a side view of another clasp embodying the invention, the catch members being shown open.

ice

FIG. 8 is a perspective view of the clasp of FIG. 7 with catch members shown closed.

FIG. 9 is a side view of a third clasp with catch members shown closed.

FIG. 10 is an end elevational view of the clasp of FIG. 9.

FIG. 11 is a sectional view similar to FIG. 4, taken on line 1111 of FIG. 10.

FIG. 12 is a perspective view of the clasp of FIGS. 911 on a reduced scale, the catch members being shown open, with parts of an associated string of beads and a FIG. 13 is a bottom view of the closed clasp of FIGS. 9-11 with ends of a string of beads engaged thereby.

FIG. 14 is a side view of a fourth clasp embodying the invention.

FIG. 15 is an end elevational view of the clasp of FIG. 14.

Referring first to FIGS. 16, there is shown a clasp C1 including a channel-shaped base member 20. Inside the base member is a leaf spring 22 secured at its center by two opposing centrally located indentations 23 formed in opposite sides 24 of the base member. The sides 24 are integrally formed with top wall 27. At each end of each side of the base member is an enlargement or eye 25. The holes in the eyes 25 on opposing sides are aligned to receive rivets 28. Pivotally secured to the rivets are ends of catch members 30a, 30b. The rivets pass through holes 26 in the eyes 25 and holes 29 in the catch members. Each catch member has a flat arcuate structure. A projection 31 is formed on the end secured by a rivet 28. This projection serves as a stop element to prevent further rotation of the catch member when the catch member is open in the position shown by catch member 3012 in FIGS. 1, 2 and 4. In this open position a free, movable end of spring 22 bears on a flattened end portion or land 33 of the catch member. The other free end 34 of each catch member may be thinned somewhat to fit snugly inside the open base member to bear on the center portion of the spring at indentations 23 when the catch members are closed. Catch member 30a is shown in closed position in FIGS. 1-4 with its free end 34 inside the base member. This arrangement prevents lateral movement of the closed arcuate catch member. Each catch member can be independently opened and closed. When the catch members are closed, the free ends of the spring 22 engage on a rather flattened end portion or land 35 adjacent to and disposed at an obtuse angle to land 33, as clearly shown at the left end of the clasp in FIG. 4. A projection 36 may be provided on each catch member extending radially outwardly of the convex edge 37 of the catch member to serve as a finger piece to facilitate opening the catch member.

A setting or crown 38 for a jewel or jewels 39 may be soldered to the flat outer side 27 of the base member. The inner concave edges 40 of the catch members define two closed yokes with the adjacent straight edges of the sides 24 of the base member. In these yokes can be engaged ends of a string of beads or necklace 42 shown in FIGS. 3, 4 and 6. Each catch member may be interposed between any two adjacent beads at either end of the necklace, such as between end beads 42 and 42" with cord 43 passing through the yokes. When the necklace is worn in conventional manner around a persons neck, the clasp C1 will be located at the back of the wearers neck with the ornamental jeweled structure outermost substantially concealing the catch members and base members of the clasp. The ends of the necklace can be engaged at any points thereof to the clasp for adjusting the length of the necklace between engaged points in the clasp.

FIGS. 7 and 8 show a clasp C2 which is similar to clasp C1 and corresponding parts are identically numbered. In this clasp, jewel setting 38a is secured by solder 44 to the outer edge 37' of catch member 30c instead of to the base member 20. The jewel setting extends outwardly of the catch member 300 so as to bear on the outer convex, curved edge 37" of catch member 30d when this catch member is closed. Thus the jewel setting 38a helps the spring 22 in holding the catch member 30d in the closed position of FIG. 8. The finger pieces 36 of catch members 30a, 3012 are omitted here. The jewel setting serves as a finger piece to facilitate opening catch member 300. The outwardly extending end projection 31 of catch member 30d can be engaged by a fingernail to open this catch member.

In FIGS. 9-13 is shown clasp C3 which is similar to clasps C1 and C2 and corresponding parts are identically numbered. The finger piece projections of catch members 30e, 30 are in the form of tubes 50a, 50b. These tubes are disposed in axial alignment when the catch members are closed as shown in FIGS. 9-11. The free end 52 of a pin 54 can be inserted through the aligned tubes to hold them closed. This end of the pin can be engaged on a garment or in the hair of a person wearing the jeweled clasp and will be held by loop 55 at the other end of the pin.

FIGS. 14 and 15 show clasp C4 which is similar to clasp C2 in that the jewel setting 38a is secured by solder 44' on catch member 30c to bear on catch member 30d when this catch member is closed. A tube 500 is secured by solder 53 longitudinally of the outer fiat side 27 of the base member a for receiving end 52' of pin 54". This pin will serve the same purpose as in clasp C3 in holding the clasp on a garment or in a persons hair.

In all forms of the invention, the clasps employ the same type of base member with an internal leaf spring having free movable ends for engaging catch members which serve as yokes for ends of a necklace. When a jewel setting is provided'on a catch member it may serve to hold an adjacent catch member in closed position.

' The clasp may be made of gold, silver or other precious metal or of base metal. The base metal may be plated with precious metal. The clasp serves a variety of functions as described and is a useful jewelry accessory. Many other types of jewel settings and jewels other than those illustrated may be used. Other types and styles of clasp members, necklaces, beads, chains, pins, etc., may be used in association with the clasps.

While We have illustrated and described the preferred embodiments of our invention, it is to be understood that we do not limit ourselves to the precise construe. tions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
