Application filed May 18, 1912. Serial No. 698,142.

To all whom it may concern Be itknown that I IBERT BERKowrrz a citizen of the United States, residing at New York, county of New York, State of New York,-have invented certain new and useful Improvements in Bracelets, of which the following is a specification. I

This invention relates to bracelets and more particularly 'to the type of expansible bracelet which accommodates itself to the size of the Wrist of the wearer and which may be placed in various positions on the forearm and fit snugly in every position.

The principal object of this invention is to produce a bracelet of this type which is easily and cheaply manufactured and can not easily get out of order.

Further objects and advantages will hereinafter appear.

In the drawing illustrating this invention, Figure 1 is 'a longitudinal section through several links of my improved eX- pansible brac'elet. Fig. 2 is a perspective View illustrating one of the units of which each link is composed. Fig. 3 is a perspec tive view illustrating another unit composing each link and cooperating with the unit illustrated in Fig. 2. Fig. 4 illustrates a blank from which the unit illustrated in Fig. 3 is formed. Fig. 5 is a view similar to Fig. 2 and illustrating a modified form of unit.

Referring to the form illustrated in Figs. 1 to 4, units 1 each consist of two curved bars 4 united by cross bars 5, 6 and 7. Bar 6 is located at one end and is reduced relative to bars 4 and forms a continuation of a shoulder 8 formed longitudinally of bars 4 which constitute a guide on which the other unit composing the link is guided. Bar 7 is rounded off and constitutes pivot about which the adjacent unit can turn. The entire unit 1 may be stamped out of flat bar metal and if desired the rounding of bar 7 can be accomplished by hand or any other suitable way.

Units 2- eachconsist of two portions 9 and 10 joined together by a reduced portion 11. This unit is inserted into the opening between the bars 4 and turned so that the reduced portion 11 meshes with the shoulders 8. then parts 9 and 10 are bent over in the between bars 5 and 7. This slot is of a length equal to the width of the portions 9 and 10, thus allowing free play with the ends 12 and 13 therein. Thetongue 14 may then be inserted in the space 15 located at the contiguous end of the unit and the two ends may be thus united and preferably swaged together so as to form a flush surface. Springs 3 are inserted before the parts 9 and 10 are bent over and are positioned between the end 11 of unit 2 and bar 6 of unit 1.

It will thus be seen that the units compo-sing each expansible, link are relatively slidable with respect to each other and are piv oted to the links adjacent thereof. By reason of the-guiding means consisting'of the shoulders 8 which Ihave provided for the units of each link. any derangement of parts of the links is avoided.

In the modified form illustrated in Fig. 5, the bars 4 of unit 1 are united by cross bars 6* and 7, the latter cross bar being rounded off-and serving as a pivot for the adjacent link. Shoulders 8 are formed on bars 4 and are reduced so as to be flush with the bar 6. Portions 4 of bars 4 are cut awayso as to make room for the ends 12 and 13 which extend the "full width of units 2'. In this form of unit. it will be noted that the part corresponding to cross bar 5 of Fig. 2 ,is omitted and bar 7 is relied upon to preserve the rigidity of the unit.

1. In a. bracelet, a plurality of expansible links. each link comprising a unit including two side bars and a plurality of cross bars connecting said side bars. said side bars bcing of reduced section adjacent their inner longitudinal edges to form guides. a second unit interlinked with said first unit and slidably guided by said guides and a spring 96 Having thus described my invention, I

connecting bar, a second unit having a reduced portion relatively to the body thereof working bet-ween said sidebars and a lateral portion engaging said shoulder and reduced cross bar and uided thereb and a spring between said reduced portion of the second unit and the reduced cross bar of the first unit. 7

3. In a bracelet, a plurality of links, each link comprising two interlinked units, one of said units having side barsand a connecting bar intermediate the ends of said side 7 bars, anotherconnec ting, bar adjacent one end of the side bars and of reduced section relatively thereto, there being a shoulder formed on one of said side bars substantially flush with the last mentioned connecting bar, a second unit having a reduced portion relatively to the body thereof working be said side bars, the latter having a. shoulder running longitudinally thereof 'andsubstantially flush with said cross bar, a second. cross bar at the other end of said side bars and adapted to serve as a pivot for the adjacent link, a second unit cooperating with said first unit and interlinked therewith, said second unit havinga reduced end portion working between saidside bars, said second unit being guided by said shoulders and said reduced cross bar, the opposite end of said second unit being-adapted to engage a bar of an adjacent link, and a spring between said. reduced cross bar and the first mentioned end of the second unit.

5. In a bracelet, a plurality of expansible links, one of said links comprising a unit having two side bars curved in the direction of their length, a cross bar intermediate the ends thereof, another cross bar at one end thereof and reduced in section-With respect to said side bars, the latter having shoulders running longitudinally thereof and substantially flush with said cross bar, a third cross bar at the other end of said side bars and adapted to serve as a pivot for the adjacent link, asecond unit cooperating With said first unit and interlinkedtherewith, said second unit having a reduced end-portion working between said side bars,'of said second unit being guided by said -shoulders and said reduced cross bar, the opposite end of vsaid second unit being adapted to engage a bar of an adjacent link, and a spring between said reduced cross bar and the first mentioned end of the second unit.

6. In a bracelet, a'plurality of expansible links, one of said links comprising a unit having two side bars and connecting cross bars, said side bars being-reduced in section adjacent to theirinner longitudinal edges, a second unit interlinkd with said first uni-t and having a reduced portion Working between said side bars and a projecting portion extending over said reduced portions and guided thereby, and a spring within said second unit and extending between one end thereof and one of said connecting bars, said spring being adapted to be compressed when the link is expanded v IBERT BERKOWITZ.
