Definitions
- a two piece clasp for a bangle bracelet is pre-assembled with a coating of material inert to solder on the abutting surfaces of the clasp and then soldered to the abutting ends of the bracelet so that the two pieces of the clasp will not be joined together by the solder.
- This invention relates to articles of jewelry, and more particularly to an improved method of permanently attaching a clasp to a so-called bangle, or hollow, bracelet and more particularly, this invention relates to the type of clasp which comprises a pair of cooperating elements which are joined to the ends of -a bracelet in abutting engagement which the bracelet is closed.
- a prior method of attaching the clasp included the steps of soldering each of the two elements of the clasp to the ends of the bracelet separately, while the clasp was open. This required great care in order to insure that the elements of the clasp would be in alignment when the bracelet was closed.
- FIGURE 1 is a perspective view of a preferred form of clasp prepared in accordance with the present invention prior to its attachment to a bracelet;
- FIGURE 2 is a plan view of the clasp shown in FIG- URE 1 assembled with the respective ends of a clasp (only fragmentary portions of which are shown) and prior to its permanent attachment thereto;
- FIGURE 3 is a view similar to FIGURE 2 but showing the clasp after being secured to the bracelet;
- FIGURE 4 shows the clasp in a finished condition with excess metal removed and the ends of the bracelet separated
- FIGURE 5 is a side elevation, on a reduced scale, showing a finished bracelet with the clasp in the closed position.
- FIGURE 1 there is shown a jewelry clasp of the type known in the trade as a single spring bangle snap, having a cat-ch, indicated generally by numeral 10 to be secured to one end of a bracelet and a keeper, indicated generally by numeral 11 to be secured to the other end of a hollow bracelet.
- a cat-ch indicated generally by numeral 10
- a keeper indicated generally by numeral 11
- this type of catch there is usually provided a generally C-shaped spring member indicated generally by numeral 12 which projects loosely through an elongated opening 13 provided in a medial portion of a fiat strip of sheet metal 14 which, in turn, is to be permanently joined transversely across one of the open ends 15 of a hollow metal bracelet.
- One of the free ends of the C-shaped spring is provided with a laterally projecting extension 16 which is permanently secured, as by soldering or welding, to the inner surface of the strip 14.
- the other of the free ends of the C-shaped spring is also provided with a lateral extension 17 of considerably greater length than the extension 16 and intended to project outwardly through an opening 18 provided in the periphery of the bracelet end 15, a sufficient distance so that the wearer of the bracelet may compress the spring to unlock the clasp by press ing against the free end of the extension 17 with the finger.
- Strip 21 is provided with a medially disposed slot 23 positioned generally in alignment with the opening 13 and adapted to receive the forwardly projecting portion of the C-sha-ped spring 12.
- the outer margins 24 and 25 taper outwardly away from each other in a direction towards the free ends of the spring and that, adjacent the strip 14 the spring arm having the actuating member 17, is provided with an inwardly directed locking recess 26.
- the width of the slot 23 is such that while the forward end of the spring may be initially inserted therein without compression of the spring, further insertion of the spring will cause the free arm to be compressed towards the fixed arm until the strip 21 engages the locking recess 26 at which point the free arm will spring outwardly to position the ledge of the recess behind the strip 21, as seen in FIGURES 2 and 3.
- the length of the recess 26 should be such that the two strips 14 and 21 will be maintained substantially in abutting relationship when the clasp is locked, and the width of the opening 13 is preferably such that there will be a slight amount of clearance between it and the free arm when the spring is in the unstressed position.
- the clasp may be unlocked by exerting pressure against the end of the extension 17 to compress the free arm of the spring to allow the recess 26 to clear the slot 23.
- the clasp is secured to a bracelet preferably by soldering the strips 14 and 21 transversely to the abutting ends 15 and 22 of the bracelet.
- the solder would not only flow into the joints between the strips 14 and 21 and the respective bracelet ends, but it would also flow between the strips 14 and 21 so that, upon cooling, the clasp would be inoperative.
- one of the elements preferably the catch 10
- a material inert to solder flux prior to assembling the catch.
- a material inert to solder flux is India ink, although any material capable of dirtying the surface of the metal will do.
- the entire catch 1.9 may be dipped in India ink and, when dried the entire surface of the spring and strip 14 will have received coatings 27 and 28 respectively which are inert to solder flux. This coating may be applied by the manufacturer and the clasp sold to the trade in this condition.
- extension 16 of the C-shaped spring is permanently secured to the strip 14, preferably by uniting the two pieces by welding, makes it possible to cut the recess 26 to a size which will insure an accurate fit when the clasp is attached to the bracelet and eliminate any excess lost motion between the two ends of the bracelet when closed.
- Method of attaching a clasp to a bangle bracelet said clasp being of the type wherein two fiat strips of metal are soldered to the respective ends of the bracelet in separable face to face abutting relationship, one of said strips having latch means attached thereto for movement in a direction transverse to the surface of said flat strips for separable engagement with the other strip, comprising the steps of coating the abutting face of one of the strips with material inert to solder flux, assembling the two strips in abutting latching engagement, assembling the clasp and ends of the bracelet in closed position, and applying flux, solder and heat to unite said strips with said bracelet ends.
- Method of attaching a clasp to a hollow bangle bracelet having two elongated parts hingedly joined to each other at their one ends for aligned abutting engagement with each other at their other ends, comprising the steps of providing two fiat metal strips Whose over-all dimensions are greater than the cross-section of the bracelet, attaching a latch to one of said strips, providing a medial opening in the other strip to operatively receive the latch therethrough with the strips in face-toface abutting engagement, coating the abutting face of one of the strips with material inert to solder flux, assembling said strips and latch in said abutting relationship, assembling said clasp with the outside faces of the strips in abutting engagement with the respective other ends of a bracelet, applying fiux, solder and heat to join said strips with the respective other ends of the bracelet while in abutting engagement, and removing the excess metal of said strips projecting outwardly of the surface of the bracelet.
- a clasp for a bangle bracelet comprising, a pair of flat strips of metal capable of being united by soldering with the respective separable ends of a bracelet in aligned abutting superposed relationship, one of said strips being provided with latch means operatively projecting through an opening provided in the other strip, the side of one strip abutting the other strip being provided with a surface which is inert with respect to soldering flux.
- a flat strip of metal having a medial opening therethrough, a generally V- References Cited shaped latch having one leg attached to one side of the P strip, with the base of the V projecting through the open- UNITED STATES ATENTS i d th ther leg free and disposed on the first side 1308741 7/1919 sgeldel 294185 of the strip, said strip being capable of bonding to a 5 1,385,117 7/1921 Dmhofer bracelet by means of a solder material, the other side 2092557 9/1937 Quamstmm 29-490 f th strip being covered with a removable coating of 2952058 9/1960 Geldwer'th 24-230 material inert to said solder material.
- FOREIGN PATENTS 17 The invention as defined in claim 16, wherein said latch is also coated with said inert material. 10 832402 4/1960 Great Bntam' 18. The invention as defined in claim 17, wherein both THOMAS H EAGER Primary Examiner sides of said strip are coated with the inert material.
