Dec. 30, 1941. w. KASTNE R EXTENSIBLE BRACELET File d June 14, 1939 III Patented Dec. 30, 1941 ax'rensmm BRACELET William 'Kastner, Irvington, N. J., assignor to Forst'ner Chain Corporation, a corporation of Application June 14, 1939:,SerialNo. 279,027
' i. 1 Claim. (6!.24-71) My present invention relates to thebracelet art,, and has particular reference to a novel construction for extension bracelets, whereby the g length of, the bracelet in closed position may be i changed as desired .-andwhereby a comparatively large extension isprovide'd in open position for comfortably removing from the wrist.
, It is the principal object of my invention t provide a bracelet construction. which permits "extension of they bracelet beyond the normalr lengthof the hands, when opened for removal fromthe wrist. Another object of my invention is to provide abracelet which permits instant detachment and ifacilitate removal and mounting ofithe bracelet. A further object of my invention is to provide 1 a construction which will insulate the metals in the "band against tarnishing caused by electrol- A further object of my invention is to provide a construction having a detachable connection, the parts being so arranged that the ends of the bracelet are never completely separated, whereby the wrist watch cannot fall to the ground.
A further object of my invention isto provide ;;an extension bracelet construction which in- ;cludes a small number of readily manufactured parts, and which is positive in action; whereby the length of the bracelet maybe adjusted tolit the wrist of the-wearer.
With the above and other objects and advantageous featuresin view, my invention consistsofa novel arrangement of partsrnoref'ully disclosed in the detailed description following, in conjunction with the accompanying drawing, and more specifically defined in the claim appended thereto.
In the drawing;
Fig. 1 is a plan view of the novel construction;
Fig. 2 is an edge view thereof;
Fig. 3 is a similar view, the clasp being open; Fig. 4 is an enlarged perspective view of the extension plate;
Figs. 5 and 6 are enlarged perspective views of the parts of the extension plate;
Fig. 7 is an enlarged perspective view showing the bracelet length adjusting parts; and
Fig. 8 is an enlarged perspective bottom plan view of the attachment device for releasableattachment to the lock arrangement of Fig. '7.
The present invention relates to extension bracelet being adjustably positioned on the lower band, and an attachment arrangement being mounted on the upper band. The essential feature of the present arrangement resides in the provision of an extension plate on the lower band whichv provides a swinging extension when the limit of the sliding extension has been reached.

Referring to the drawing, the. bracelet I0 includesfa lower strap portion H, see Figs. 2 and,3, which has an end hook 12 for attachment to the bail at one side of a wrist watch, and an extension plate i3 and slide link l4 through which an upper strap portion l5 may be 1on gitudinally moved; this upper strap portion l5 also having an end hooklG for attachment to the other bail of the wrist watch. The lock device" I l "is adjustablyslidably positioned on the strap portion II, and maybe locked in place alongthe length thereof so as to change the efiective length of the bracelet, the strap portion l5 having an attaching element 18 which is detachably securable to the lock device I'l.
[bent portion 22 of the lower portion I9,
bracelets of the type in which two bands are t mounted in overlapping relation, a lock device comprises base 21 having a flt qm plate 28 The extension plate l3 ispreferably made with a steel surface on one. side'and a'gold surfacev on the other side for a purpose hereinafter to be described, This canflbe doneby plating or the like; howeventoavoid the expense and difficulty-of plating or otherwisecoating one side only, I have devised the construction illustrated in Figs. 4,5 and 6. In the illustrated construction, the plate 13 comprises a lower plate portion I9, preferably of gold; curved to fit the wrist, and
'havingintegral'side flanges 20. The portion 19 is also provided at oneend with the spaced ears 2|, and at the opposite'end with a reentrantly bent portion 22 having integral, laterally extendmg portions forming pivot pins 23. The side link 14 is pivotally mounted on the pivot pin 23.
The upper plate portion 24 preferably stamped from sheet steel, and curved to fit between the flanges 20, is provided at one end with an ear 25 adapted to fit between the ears 2|, the opposite end being pinched under the reentrantly ears 2| and 25 are mounted on a pivot pin 26 of a conventional end connector clamped to the strap portion II. i i l The adjustment device and detachable connection may be of any well-known type; however, for purposes of illustration only, I have shown the construction described in detail in my copending application Serial No. 252,174, entitled Watch attachment. Inthe illustrated construction, see Figs. 5 and 6, the lock device I! The ' andtwo side plates 29, each side plate having a longitudinal slot 30 for receiving the end lug 3| of a connector element 32. The connector element 32 has a flat plate portion 33 adapted base plate 28; the connector element 32 extends upwardly and then horizontallyand then downwardly to form a hook receiving chamber which has a slot 34 for receiving connector hooks as hereinafter explained.
1 portion 35, which when manually pressed down" rotates the camend 38 firmly against the plate the lock device I], the extension plate I3 is folded over the lower strap H so that it acts as a separator between the straps II and IS, the upper strap l5 nesting between the flanges I9, asin Fig. 2. In removing the strap from the wrist, the attachment device I8 is unhooked from the adjustment look I! and the upper strap l5 slides,
in the usual manner until the slide link 14 stops further movement. At this point; unfolding of the extension plate l3 to the position shown in p gigFig. 3 will afiord an additional extension. A cam element35 is rotatably mounted on a pivot 36 which has its ends secured in the plates 29 the cam having an outwardly extending linger The use of the described'extension plate 13, havir'ig opposite gold and steel surfaces, as a yseparator between the overlapping portions of 33 so as to thrust the plate downwardly into locking engagement with the strap portion Hr the straps H1 and I 5, is highly advantageous when utilizing the type of strap illustrated,
. wherein a flexible steel mesh 50 is provided with an upper outer covering of gold strips 5|. The

The two hook elements are resiliently urged away from each other by an expansion spring (not shown) housed on the base '39 an which has end lugs 50 which extend through and are received in the slots 42; H
