Patented Feb. 15 1927. 11617t954 p UNITED STATES PATENT OFFICE. JACQUES KREISLER, OF NEW ROCHELLE, NEW YORK. WRIST-WATCH STRAP. Application filcd August 5,1926. Serial No. 127,348. This iiiv(-@jitioii i-elzites to ii-nproveiiieiits in ivi-i@,.t wateli sti-aps aiid the 'pi-imary object thei-eof is to provide, ,i novel an-d iinproved ineans for attieliiiicr the strap in an adjust.ible positioii on the wrist according to the desii,ed size. One, of the objects of iii3, inveiitioii is to I)i@ovi(.1e a wi-ist watch strap i-neltiding novel -iiid iinpi-oved liaeans for attaclirfient to the 10 eii(.Is of a cliain with pi-ovision for lengtlieiiiiig tlio strap in one position wliile removing it f rom the wrist, and locking the trap in a second position when adjustably fitted to tlle desired size of the wrist. 15 Anotlier object of my ini,entio-n is to rovide ,i ivrist watch strap incltidiiig leiigt nin- means in conjunction with a chain and ineans @or locking the said lengtliening means in sucli manner as to leave practically 20 the entire' length of chain exposed to view. To enable others skilled in the art to more fully comprehend the underlying featiires of nly inventioii tli,,tt they may embody the same in the variotis pi@,ictical uses and puPposes 25 to ivbich it is capable, drawincrs depictin t I)refei-red form of the inveiiti(@n are annexed liereto as part of my disclosure wliereinFig. 1 is a view sliowing the application of niy in'vention to a chaiii. 30 Fig. 2 is a side view showirig the -len(rthening device closed. C, Fig. 3 is a similar view to Fig. 2 witli the lengthening device partially opei. Fig. i is an enlarged plan of the lengti-ieii35 ing device showing its relation to the liec-per ,tiid ch, tin. Fig. 5 is a sectional view taken on the Iiii.e 5-5 of Fi(r. 4. Fi@@. .6 is a sectional view taken on the line 40 6-6 of Fig. 4. Fig. 7 is a sectional view taken on.the line 7-7 of Fi(r. 2. Refei-i-in'; now to the drawings wherein lik(@, referenee cliaracters designate corre45 st)onding parts tlirotigliotit the several vie-8vs, 51 6 desi(,nate the ends of a ebain strap of aiiy coiiventionil (lesigii aiid provi(led witli aijy stiitable type of cateli or fisteniiig mozins c,il)able of being connected t@o a ivrist wateli. r)o 4y inventioii proper comprises a keeper in the foriii of a stibstantiallv rectangulir plate 7 -,vith pai-allel sides 8, 9 provided witli opposed tipertures 10. The sides 8, 9 are proi,itle(i witb grooves lt oii tl)eir iiiii(,,r faces r) 5 which function to lock the lengthening means in the manner further to be describe&. As sbo-"-ii by 14'ig. 4 of the drawing, one end 12 of the'ehain is attached to a pin 13 baviiig clepressible-spi-ing tensioned ends 14, 15 cooperatiiig witli a spi-ing 16, tlle end Jr) 60 beiiig pi-ovided with a serrated, toothed ext nsioti 17 iiioval)le tliroti-h -,v slot in the piii e t-I whereby the said end niay be (lisengaged froiii t)ne of the apertures 10 of the keeper (tnd the end of the chain adiustal)ly posi- 6r) tioned to the desired length. Pi-*@otally connected between the sides of the keeper.and at one end thereof, I have provided t connector plate 18 having an eild pintle 19, said plate being-sligl-itly ciir.ved to 70 conform to the shape of the -,vrist. Tlle width of ilie, connector 1)late is slilhtly less than the width of the keeper so that Nvhen folded or swung over will lie freely betweei) the sides 8, 9 as shonvn bv Fig. 7. 75 Hinged as at 20 to the connector plate 18 is a second and similar connector plate 21, also ciirved slightly and -%vhen fully opened is a continuation of the keeper. It will be observed, ho-%vever, that the connector plate 50 21 is slightlv wider at its greatest ividth 23 than the coiinector, plate 18 so that wh,-,ii folded over or swung between the sides of the keet)er, the connecior plate will snap into the (rrooves 11 and thus lock both of the 85 plates. The opposite end 24 of the ebain is perinairiently fastened to the end of the second connector plate 21 so that the entire adjiistnient in the leri-7th of the ebaiii is eJ.Tected throucrh the movable pin between the sides 90 of the Iceeper. From the tibove it -will be seen tba-t the ei-ltire leiigth of the chain is exposed and that while the overlapping connector plates extend beyond the end of the l@eeper, said 95 plates are covered by the chain as disclosed by Figs. 1 and 2 of the drawing. In order to reduce the weiglit an(I ,tffoi.-d some ventilation, the major poi-tion of the connectoi- pl,,ites i-nay be etit oiit -%iitli stiit- ioo able fanciftil desigiis or iiiitials if so desii-(@d, or the width of the plates I)c iii,,ttei-i-,tlly redticed cxcel)t tliit-, I)oitioii Ni,hi(,Ii fi-ictionilly en(y@t(,es tlie sides (f the l@ecl)er to lock tlio coiinector plates tbereto.

In actual pi-actice but two coiinector plates
