Application July 2, 1936, Serial No. 88,629 2 Claims. The present invention pertains to a novel wrist watch bracelet of such construction and design as to be equally appropriate for men, women and children. The principal object of the invention is to pro vide an inexpensive watch bracelet having an attractive appearance and desirable qualities as to strength, durability, ?exibility, and adjust ability. The bracelet comprises several parallel strands and each strand consists of hollow balls or beads united by headed wire links. This type of chain may be manufactured very cheaply by production processes. Although having consider able strength, the wire links may be readily cut 15 to adjust the chain to the desired length. Novel effects may be obtained in the plating of the chain and in various arrangements of the strands. The invention further includes anchoring de 20 vices for the ends of the chain. These are in. the nature of simple stampings having no mov able parts and designed to hold the ends of the chains by friction. Consequently, the ends are readily inserted but do not become released acci dentally, inasmuch as some degree of force is 25 necessary to remove them. 30 one of the strands; Figure 2 is a plan view of one of the anchoring devices, showing also the ends of the chain re ceived therein; - Figure 3 is a section on the line 3—3 of Fig 35 ure 1; Figure 4 is a section on the line 4——4 of Fig ure 2, and Figure 5 is a plan view of a wrist watch equipped with a bracelet according to the in 40 vention. Reference to these views will now be made by use of like characters that are employed to desig nate corresponding parts throughout. In Figures 1 and 3 is illustrated the chain from which the watch bracelet is made. The chain consists of hollow balls I joined together by inter vening solid links 2. The assembly is made by means of suitable machinery, and in connection therewith, each of the balls is apertured at dia metrically opposite points as indicated by the numeral 3. eight times actual size, but the balls may be as small as T16 inch in diameter. The bracelet consists of several parallel chains as shown in Figures 2 and 5, and the ends of Cl the chains are held in locking or anchoring de vices as illustrated in Figures 2 and 4. Each such anchoring device consists of a stamping shaped to form a number of parallel troughs 6 equal in number to the chains or strands used 10 in assembling the strap or bracelet. Adjacent troughs are de?ned or separated by means of inward ridges 1 formed in the metal. At one end of the troughs, the stamping is fastened to the watch case or to a part of the clasp, as will pres 15 ently app-ear. At the other end, the outer side walls of the outer troughs are bent over or partly across these troughs in the form of cheeks 8. Further, the metal at the unattached end of the stamping is also bent over in the form of checks 20 9 twice as large as the cheeks 8, each of the cheeks 9 extending partly across and along to adjacent troughs. The cheeks 8 and 9 are of spherical con?gura tion for a purpose presently to be described. The invention is fully disclosed by way of ex ample in the following description and in the accompanying drawing in which Figure l is an elevation, partly in section, of The links 2 consist of Wire stock and are headed at 4 within the balls I . (Cl. 63—4) shown in Figures 1, 2, 3, and 4 are approximately The heads are also rounded at 5 to facilitate swinging of the links relatively to the balls and thereby increas 55 ing the ?exibility of the chain. The parts as The intervening space I0 between them is slightly less in width than the diameter of the links 2. As previously indicated, stampings of the char acter described are attached to opposite sides of the watch case H as indicated by the numeral 30 I2 in Figure 5. One of the end balls of each chain is retained in each of the troughs 6. For the purpose of assembly in this manner, the cheeks 8 and 9 are spaced from the attached end of the stamping a distance at least equal to the 35 diameter of the balls I to permit insertion of the balls in the troughs and beneath the cheeks. The end balls must be pulled under the cheeks with a small amount of force, inasmuch as the checks are spaced from the bottoms of the troughs a distance slightly less than diameter of the balls. Consequently, the balls are held under the cheeks by pressure of the cheeks therein. As'shown in Figure 2, each of the spaces l0 widens at its ends as indicated by the numeral 13. Consequently, the links 2 are readily in serted in one end of a space Ill and accommodated in the other end, but are prevented from return ing to the intermediate part of the’ space in the - event that the adjacent ball turns in the anchor ing device. 'The remaining end balls of the chains are re ceived in similar anchors l4 and I5 to which are attached the complementary clasp elements It; 2.. 2,119,436 and IT. The attached end of each of the an choring devices is preferably curled at I8 around leased because of the force required to remove them. It will be understood however, that, in a stem l9 comprised in the Watch case II and p so far as the novel chain is concerned, other types of anchoring devices may be used; , - the clasp elements I6, 11.

V described has numerous advantages. 10 beads. It possesses In this connection, the chain must ini tially have-at least therequired length, and can be easily cut inasmuch as the links 2, consistof 10 the appended claims. What I claim is: 1. A bracelet comprising a beaded chain, a ' comparatively thin wire. Great ?exibility is made possible by the swivel movement of the stamped metal vend anchor shaped to form. a trough with spaced cheeks overlying the same, the 15 rounded heads 4 within the balls I. ' Adjustments can be made within a ?ne range becauseof the 'end bead being received on the bottom of said small diameter of the beads. The chain may be plated with any desired metal ‘or adjacent strands may be plated with different 20 metals for design effects. Further, the appear ance may again be modi?ed by staggeringthe beads of adjacent strands. As distinguished from other metal or link type exerting spring pressure on said bead against said watch bracelets, the device of the present inven tion does not catch or pull the hair owing to the spherical shape of they members I and the re moteness of the apertures 3 from the skin. For the same reason, there is no pinching of the skin. With regard to the anchoring devices, these 30 are inexpensively manufactured by a stamping process and are not complicated by moving parts. The end balls are readily inserted therein and held frictionally, but cannot be accidentally re trough and beneath said’ cheeks, said cheeks bottom. ‘ 2. A bracelet for a Wrist Watch or the like com prising spaced hollow beads apertured at di ametrically opposite points, wire links disposed 20 between said beads, each link extending into two of said apertures, a stamped metal end anchor shaped to form a trough with spaced cheeks overlying the bottom of the trough, the end bead 25 being received on the bottom of said trough and beneathsaid cheeks, said cheeks exerting spring pressure on said bead against said bottom, the intermediate part of the space between 7. said cheeks being narrower than the diameter of said 30 links.
