6 Claims.

This invention relates to band attachmentmeans for wrist watches. The object of the invention is to provide a simplified means for attaching or connecting the ends of. a wrist band or strap to a wrist watch. The construction of the improved device is such as to greatly facilitate the attachment or removal of the wrist band and provide a secure and positive means of attachment so that the possibility of the watch becoming inadvertently disconnected from the wrist band and accordingly lost will be avoided.

According to present construction, the opposite ends of a wrist watch are each provided with a pair of lugs between which a rod or bar extends and the same passes through a permanentlyformed loop on the end of the wrist band. The rod or bar which connects the two lugs is usually provided with spring-pressed studs at its ends which snap into engagement with holes provided in the lugs. An arrangement of this character is of relatively delicate construction, and to disconnect the ends of the wrist strap or band when it is desired to replace the band, often requires the use of tools. Also, it often occurs that when replacing a wrist band the studs do not firmly engage the holes in the lugs and the band becomes later inadvertently disengaged from the watch and the watch lost.

With my improved Wrist band connection means, the cross bar or rod extending between the lugs may, if desired, be made integral with the lugs and may thus be of sturdy construction. Also, with my improved connection means, the ends of the wrist band may be very easily engaged the bar or rod from its position between the lugs, so that the possibility of the watch becoming lost by faulty replacement of the bar is prevented.

In the accompanying drawing, wherein an embodiment of the invention is shown, Fig. 1 is a face view of a part of a Wrist watch showing one of the ends of a wrist band attached thereto according to my invention, with parts of the band broken away to disclose construction; Fig. 2 is a view of. the rear face of the structure of Fig. 1; Fig. 3 is a perspective View of the stiiening member in its folded position, but removed from within the wrist band; Fig. 4 is a sectional view on the line 4--4 of Fig. l, looking in the direction of the arrows; Fig. 5 is a face view of one end of the wrist band before the same is bent into loop formation; and Fig. 6 is a sectional view on the line 6--6 ofl Fig. 2, looking in the direction of the arrows.

about the bar or rod without requiring removal of y In the drawing, I indicates the case of a wrist watch of conventional construction, such case being provided ateach of its ends with the two spaced lugs indicated at 2, connected by the cross bar or rod 3 in the usual way. This crossbar or rod 3 may be of the removable kind, or it may be a permanent member extending between the two lugs 2 and formed integral therewith. The wrist band or strap 4 may be formed of any suitable flexible material such as leather, fabric, or the like, and it is preferably composed of several layers or plies, two of which are shown at 5 and 6 which are stitched together at their edges along longitudinal lines as at I. Sandwiched between the two layers or

piles

5 and 6, near the end of the band,kis a metal plate or stifening member 8 held in position by means of the

stitches

5 and 6 and also by means of transversely extending stitches 9 and I i), or other additional stitching if necessary.

L The position of the strip 8 before being bent or doubled over to loop formation is shown in Fig. 5. Near one of its ends the strip 8 is provided with a pair of spaced, upwardly extending spring projections or tongues II and it is. also provided with additional projections I2 and I3 separated from the projections I I by means of an intervening space I4. All of the projections II, I2 and I3 are formed by distorting the metal of the body of the strip 8.

The band 4 is provided near its end with a cut-out opening I5 extending through the ply 5 and through which that portion of the strip provided with the various projections I I, I2 and I3 is exposed, as clearly shown in Figs. 2 and 5. In placing the band on the watch, the end of the same is inserted between the watch and the bar 3 and the band and enclosed stiening member 8 is bent to loop formation on the transverse line I6 in Fig. 5. The stiffening member or strip 8 in the bent or doubled-over formation is shown in Fig. 3.

A sliding metal loop member I1 extends around the band and it is arranged to be forcibly moved into the space I4 between the projections II, I2 and I3. The loop member I1 is formed on its under side with a depressed portion I8 which moves between the spring projections II and comes into contact or abutment with the stopy I3. The additional stops I2 impinge against the ends .of the band so that when the band is moved toward the watch, its movement in that direction is limited by the stops I2 and I3. The spring projections or tongues I I, co-operating with xed stops I2 and I3 confine it within the space I4 2 and hold it against inadvertent displacement. It will remain in the space I4 until it is manually drawn over the spring tongues II and moved in a direction away from the Watch when it is desired to remove the band from its attachment to the watch. The metal comprising the strip 8 is of sufficient stiffness to cause the band to maintain its looped portion, and the loop I'I, locked in position in the space I 4 as heretofore described, provides a closed loop affording a secure means for holding the ends of the wrist band attached to the watch.

What I claim is:

l. A device of the character described Icomprising, a Wrist Watch band composed of Lses/'eral plies secured together, a flat metal strip Adisposed between the plies adjacent one end ofthe band, the band and the strip being iboth #doubled over to form a bar-embracing loop, said stri-p vhaving spaced stops, the band having an opening in one "of its plies through which .said stops are exposed, .and .a l'o'op `member extending around the band and :adaptedrto be ,.movedfto embrace the doubled-over Yportions v.thereof and when so moved to 'be disposed :between and .restrained by the stops.

2.Ardevice 4of the character described comprising a wrist band vcomposed of two plies stitched together, 'a strip of nat metal located between Lthe fpliesfof lthe band near one end .thereo, .said .strip being adapted .to normally retain said end Yof the band in looped position, one of the iplies `of the 'band being `formed with an aperture through whchla portion of the strip is exposed, a loop surrounding the band `and adapted to be :moved to surround the doubled-over portions :thereof to holdv the end of the .band in looped formation, andlrneans on the exposed portion .ofthe strip for engaging said loop and holding it in position around fthe doubled-over portions of the band.
