arraa eras PATENT HEAD-CLASP BASE.

Application filed May 4, 1922, Serial No. 558,496.

To all whom it may concern Be it known that I, CHARLES GRUNEBAUM, a citizen of the United States, residing at the city of Philadelphia, county of Philadelphia, and State of Iennsylvania, have invented a certain new and useful Improved Bead-Clasp Base, of which the following is a specification.

This invention, generally stated, has relation to a bead-clasp base such as is disclosed in my co-pending application for Letters Patent as filed February 25, 1922, serially numbered 539,076, and has more especial relation to an improvement thereon. lVhile the device disclosed in my said application is admirably adapted for the purposes designed, I have found in certain instances. particularly in the case of a string of beads having an intrinsic value, that an added or double security is desirable. For instance as at present designed should the beadlasp become accidently detached, loss of the string of beads may ensue.

The leading object of the present invention is to provide a construction wherein not only are all the advantages of my previously mentioned base retained but means provided for preventing the loss of a necklace should the conventional bead-clasp become detached or unfastened. Other and further objects not at this time referred to will appear hereinafter.

The invention consists of the improvements hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. 1, is a view in elevation of a portion of a necklace illustrating one form of safety attachment as applied to my beadclasp base with the clasp parts in secured position.

Fig. 2, is a similar view of a slightly modified form and illustrating the clasp parts in un-secured position.

Fig. 3, is an end view illustrating one of the base constructions shown in Figs. 1 and 2, and

Fig. 4:, is a view in elevation of a portion of a necklace illustrating a still; further modified form of safety attachment.

Renewed October 10, 1923.

For the purpose of illustrating my invention I have shown in the accompanying drawings several forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

In the drawing 1011 designate claspparts such as are employed by jewelers in high grade strings of beads although obviously other types of clasps may be employed. In practice an end of cord 12 is secured with respect to body part 10 of such clasp and the other end of the cord secured with respect to the slide 11, it being understood that these parts are equipped with rings or eyes 13 to receive the cord ends. Each end of the cord is looped to form. a bight, a bight being passed through a or eye 13 and the runs of that par ticular portion of the cord tied together, preferably at intervals, the resultant knots being located between adjacent beads 1 1. The bases of which there are two for each necklace,'each comprise a tubular member 15. one end of which is flared as at 16 and the walls of the opposite end of which is provided with opposed, substantially V- shaped notches 17 of which'there are two. With each base in proper position the notches of members 15 engage over the rings or eyes of the clasp-parts so that each bight of cord 12 is entirely concealed from view and thoroughly protected by a member. The flared or bell-shaped end of each member 15 receives an end bead. Referring now more particularly to Figs. 1 and 3, each member 15 has loosely mounted thereon in concentric relation therewith a ring 18 provided with an eye 19. Interposed between the eyes 19 is a separable connection for maintaining the necklace upon the neck of the wearer should the clasp parts .become detached. In the drawings the connection is shown as being a chain 20 secured to one of said rings 18 and a snapring 21 secured to the other ring 18 whereby the chain may be coupled to the snap ring. The object of having the rings 18 loosely mounted upon the bases is so that should the clasp-parts together with the bases be caused to move around a horizontal axis, the chain and its snap-ring will remain stationary in contradistinction to being wound around the clasp and bases. I have shown in Fig. :2, one base provided with a fixed eye 22. In practice the eye 22 is soldered to the base preferably in abutting relation with the rim 16 of member 15. The companion base is provided with a loosely mounted ring 18. In either event should the clasp become detached, as shown in Fig. 2, the chain connection serves to maintain the string of beads in connected relation so that they are retained upon the neck of the wearer. I have found if only one of the bases is provided with a loose ring 18, as shown in Fig. 2, that this is sufficient to prevent the chain connection from becoming tangled in the bead-clasp parts. However I have in mind providing each base with a fixed eye 22 as shown in Fig. 4. Also instead of having the snap ring carried directly by a base-part I may connect a two-part chain to the bases and interpose in these chain parts a snap-ring. While I have described the present safety attachment as supported by my special bases obviously my safety attachment may be effectively used in conjunction with other types of bead-clasp bases.

It will now be apparent that I have de vised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiments thereof which have been found in practice to give satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

.Vhat I claim is:

1. In a necklace, a clasp, a cord provided with beads secured with respect to said clasp, a pair of sleeves each of which is flared at one end for bead accommodation, and each of which is shaped at its opposite end for engaging over the parts of said clasp engaged by said cord and a separable connection interposedbetween and connected to said bases for maintaining the string of beads in connected relation should the clasp parts become separated.

2. In a necklace, a clasp, a cord provided with beads secured with respect to said clasp. a pair of sleeves each of which is flared at one end for bead accommodation, and each of which is shaped at its opposite end for engaging over the parts of said clasp engaged by said cord, means carried each sleeve to receive a chain and snap-ring connection and a chain and snapring interposed between said means.

3. in a necklace, the combination of a string of heads, a tubular base secured at each end of said string of beads, aclasp oetachably connecting said bases, a ring loosely arranged in concentric relation with one of the bases and a chain including a snap-ring connected between said ring and the other of said bases.

4. In a necklace, the combination of astring of beads, a tubular base secured at each end of said string of heads, a clasp detaehably connecting said bases, a ring arranged in concentric relation with one of the bases and loosely mounted thereon said ring having an eye and a chain including a snap-ring connected between said eye and the other of said bases.

As a new article of manufacture a base for necklaces comprising a. tubular member flared at one end for bead accommodation said member having mounted thereon and extended therefrom means to receive an end of a safety chain connection.

6. As a new article of manufacture a base for necklaces comprising a tubular member flared at one end for bead accommodation said member having loosely mounted thereon in concentric relation therewith a ring adapted to receive one end of a safety chain connection.

7. A device as described in claim 6, characterized by an eye extended from said ring to receive said connection.

In testimony whereof, I have hereunto signed my name.

CHAS. GRUNEBAUM.
