Application filed May 9,

widths and thicknesses of said bands to suit the size of the watch-holding frame or {case and the arm of the wearer, and with due regard to symmetry or '-l1armony inthe use of the wrist-watch product. I I I The details of structure of the improve ment will be fully hereinafter described in connection with the accompanying sheet of drawings, in 'which latter Figure 1 is a plan view of thewrist-watch and its attaching band or'strap, showing my improved mounting-connection with a medium width of strap; Fig. 2, a side elevation of the complete structure; 3, afragmentary plan, partly in section, showing the-improved mounting-connectionv herein; Fig. 4, a detail section of the mounting-connection, taken on the dotted line i, 4-, of Figs. Qand 3; 5, a perspectiveof one of the sleeves forming a part of the said mounting-connection, such sleeve in this view having a nar row slot for a thin band or strap; Fig. 6, a

, plan of the strip. of sheet metal used in forming the sleeve seen in Fig. 5; Fig. 7, aperspective similar to Fig. sleeve v. th a wide slot for a heavier or thicker band or strap; and Fig. 8, a plan of the strip of sheet-metal used in forming the sleeve seen in Fig. 7.

In these views of the drawings, A indicates the usual watch-holding frame adapted tocontain the encased dialed movement or watch-proper I) and having spaced lugsQ. C, at its opposite ends for the hinged or pliable reception of the opposite ends of the wrist ban d or strap I). f i

T he wristband, in use, made in different widths and of different thicknesses of mate-' rial, and it is desirable that the hinged conned tion or coupling member between the said opposite ends of it be thicknesses and widths- To snchend nay-in '9 is formed from a fiat rectangular st 5, but showing the constituted so as to'prop erly conform to or well meet its sald varying 1927. Serial No. 190,024.

tl'iei'efore, is composed of a short lengtho-f tubing 9 that forms a sleeve to fit freely, but not loosely,between each of the pairs of extend d. lugs C, C, at the opposite ends of the z 3 iding frame A. Each ofthe sleeves rip of sheet1netal or blank, as shown at a; and b,*in

Figs. 6 and 8, respectively, the strip a, in

Fig. 6, having at one end thereof an'elongated notch'or cut-out, shouldered portion 0;, and

the strip 0, in Fig. 8, having at-both ends.

thereof similar notches I). In forming the tubing; from these strips the strip a, of Fig.

'6, is used to produce theslceve of Fig. 5, to

accommodate the eye'or loop 10 at each end of the wrist-band D that is slipped into place" within the sleeve, (which latter is of spring or resilient metal), by opening the slit-b.6- tween the opposite adjacent ends of the elasv tically closed strip a. When the said eye has reached the position of the notch a, so as to fully register therewith,itbecomes automatically seated or snaps into its proper place in the sleevefthe shouldered ends ofthe notch preventingits endwise movement or displacei ent from the sleeve until required to do So .a-nc. accomplished by spreading open the said sprin -closed meeting ends of the tubingstrip a. In order to meet the varying widths of wrist-bands the sleeves 9 are all made to fit freely, as above stated, between the pairs of lugsC, G, on, thewatch-holding frame, but the len 'th of notches a is made to vary,

a longer notch to suit the Wide band "and the shorter notch'to SLUt' the narrow band,

all to suit the varied conditions connected with the individual taste and the size of the arm or wrist of the wearer. practice, however, it has been found necessary to allow for but about threewidths of bands, viz: abroad, a medium, and anarrow In actual f hand, and sleeves with corresponding lengths of notchesce-to suit'the width of band. are selected for the demands of the tradeh Tofur: ther provide for thicker bands I notch uthe strip bat its opposite ends,as above stated, and, when the said opposite ends are brought together under the tension of-tho spring metal thereof, the notches Z)" duly register to form a broader slot or opening forthe accommodation of the thicker orheavier metalfof the eye orloop 10 atthe opposite ends of'the said'band. The-adjustment or change from a broad to a narrowband, or the reverse, can be readily made by the sub; stitution of sleeves havmg'long' mediiim,

short notches of bands.

A tubular connecting axle or pintle 11, havinig to suit such dilferent widths b ends 12, 12, is provided Within each of the said sleeves 9 and, coincidentally, Within the endloops 10, 10, of the band, to flexibly connect the latter With the opposite lugged ends of the Watch-holding frame A. V The said bearingends 12 oi the pintle 11 engage minute openings 13 in the lugs C and suchpin tle, being hollow, is thereby adapted to acconriodate the said bearing-eni'ls in a resiliently-cxtcnded manner by the additional use of an internal spiral spring lei, as best seen in Fig. 3. A short tubular fillenplug l5 is inserted, with a drive-fit, in each endof said hollow pintle ll to prevent any undue movement oilsaid bearing-ends. Thus, the said pintle can'bo conveniently placed between the lu With its spring-extended bearing-ends in the openings a 18 for the free flexible connection (If the opposite loop-ends 01"- the Wrist-band therein.

The bearing-ends can be easily displaced by simply inserting a pointed instrument in either opening 13 and compressing either 01 said bearing-ends until it clearsthe inner face of the adjacent lug. The compression of either ofthe little spring-extended spindles 12 will permit themain spindle or pintle 11 to be inserted or ithdrawn to and from place between the said pairs of lugs C, C, for

' the attachment or detachment, as'the case-may be, of the encased tinie-piece between the opposite ends ofthe rist-band. Intermediate the said. opposite ends of the Wristband is reduced, internally-headed bearin a provided a suitable clasp E to connect, in adjusted position on the Wrist. the customary pair of arc-shaped members that form the said Wrist-band.

The opposite ends of the sleeves 9 are prel erably, but not essentially,inwardly flared, as best seen in Fig. 3, to cover or inclose the gap over the ends of the eyes or loops 10 and impart the-desired Worlnnanlike and aesthetic effect or finish to the device for use.

It is intended that the miproved mounting herein is adapted for similar expansiblely encompassing said tubular'pintle, and a longitudinally-split elastically closed auxilpassing the said tubular pintle and loop formation between thelugs and having a longitudinal slot adapted to accommodate the width of the Wrist band free from cross-Wise shifting of the mounting.

In testimony whereof I hereunto affix my signature. i
