-To all'whom itmay concern: a I Be it known that I, LIEYER L. ROBBINS, -a citizen of the United States-{and aresi- "dent of the city, county, and State of New MEYER L. ROBBINS, or NEW YORK, N; .Y.

WATCH-BRACELET.

Yorkyand whose post-office address'is.3 33 Central Parkwestpin saidcity, have 1nvented certain new and useful Improve-- lowing is a specification.

ments in Watch-Bracelets, of which the fol-' This invention relates to a detachable link for the end of a bracelet and means for securing the link to the watch case. Generally the wearer of a watch bracelet desires to use thewatch for other purposes, such as achatelaine, brooch watcl1, etc., and as'a bracelet watch isgeneralIy-prOVided with a small link or other means of attachment on its edge, when" such a watch is worn-as above mentioned, it is readily apparent that a bracelet watch is being used... Thus, convertible watchesof this type are not much in use.

The object, thereforefof this invention 1s toprovide a watch case with means *to 7 which same; Fig. 9? is a plan view, partly in seccarried out by my invention, a more'particu- I'L'CtIOII of the arrows; Fig. 7 is a plan view which my improved end link maybesecured and detached at will, the means on f the watch case not being discernible, so that the wearer can use the watch for other purposes than for a bracelet watch, without it being known that a bracelet watch is being used. These and other improvements are lar description of which appears below.

Throughout the various views -of the drawings, similar reference characters-designa'te slmilar parts.

It is obvious that" my mproved detachable end' link and means for securing the. same to thewatch case may be used in connection"with any form of agbracelet, al-' though in this-instance I have shown a soof aseries of outer links 1, and inner links 2 withretracting springs contained between the inner and outer links. T hewatc'h 3 has a link 4 to which one'end ofthe bracelet chain is'attach'ech'a special form of detachable link 5 being used,=if desired.

The back 6 of the watch is hinged to the center 7- by a hingef'S which is mounted on the pintle 9 which extendsthrou'ghthe cen- The detachable e'nd'link consists of two resilient side members 11, connected fat'one endby the crOsspiece IQ, which is engaged by the inner link of. the adjoining link; gThef opposite ends of the side members 111 are off-set as at 13 and on'the ends'of said off-set portions are formed inwardly extending studs 1a which extend intothefrecesses 10 the same; andFig. i2 is perspective view. :of thesame.

called expansible bracelet which is made up 1 ter of the hinge; recesses 10 being formed in J the ends of the hinge.

in the watchfcase hingef A sliding collar 1 5 is mounted on the link anddraws theside members 11 together and holds the 'studs'14:

in the recesses 1 0.' Depressions 16 are formed in the side members 11 adjacent the oflfset portions 13 to hold the, collar.15"inplace and prevent the same from inadvertently slipping'back and allowing the. link to free itself fromthe watch. A blockl'lis secured to'the'inner side of oneof'the, side members to limit. the movement ofthe side- 1members toward one another when the collar .1577 moved forward into pos1t1on'ad-]acent the I ofF-setportions '13, and the stu'dsliare position in the recesses 10;

From thellfor'egolhgi e operation of the I detachable linkwill be readily understood; I

To removethe link fromthe'watch, thecol- .lar'15fis slid awavfrom theoif-set portions 13,which" allows the armsill to-spring away from one another, the studs 14 moving out of'the recesses 10"so that the link can be readily removed.

In the embodiment of my inventio'n'shown in Figs. 7, Sand .9, I have shown a'link member having two trough-shaped side members 18 connected at the ends by'cross pieces 19 and intermediate the ends by a cross piece 20. Slidably mounted in said link is the catch member 21 having resilient tongues 22 and 23. The tongue 23 is slit as at 24,

dividing it into two portions 25, the ends of 1 said portions being'ofi-set as at 26 and at? the ends of said offset portions are formed the studs 14 which are adapted to enter the 1 recesse'slO.inlhewateh case-hinge. In order to hold the two parts 25 togetherso-that the tstuds remain inplace in the ree'esses 10, a -slidingecellar 27 is mounted on thetongue 23. A recess 28 is formed in the tongue '22 Y which engages thecross-pieee .ZOtoholdthe catch; member 21 within the link member when the catch member isthus placed. An enlarged-serrated portion 29 is formed on theend-'of-thetongue 22 for engagement by thefinger nail sothat the tongue 22 .canbe pressed down and the recess 28;forced out:

of engagement i h the, cross-piece 20 and the catch member-drawn out otthe link' Inember so that when it is desired to remove the link from the watch, the collar 27 is moved awayfrom theends-25 allowing them -to separateiso that'the studs comeoutof engagement with-the recesses 10 in thewatch case hinge. ,A recess -30w i'siormed in the link 30 member for -the-reeention ofthe collar 27 when the catch memberi'is within-the link wmember. .As shown in Fig. 9 -.depressions ,a;mayjbeformed i-n thesides of the ends-25 to holdthe collar 27 in position (and prevent th sam s r sli ing may ,iallow s a p diese h nds- .fInthe; modifieation shown jnF-igs. 10, ll
