COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEWV JERSEY ras'rnnr a roe RIST WATCH sTRAPs Application filed. April as,

This invention relates to improvements in fasteners for wrist watch bands, with special reference to types in which the main portions of the band are made of soft, flexible material, such as finished leather or similar material.

Ordinary leather bands, used for this purpose, are objectionable, for the reason that they require threading the end of one section of the strap into the buckle loop. Unless this is done very carefully, the watch may be accidentally dropped. Furthermore, after the end of the strap has been threaded through the loop, it must be engaged with the tongue of the buckle, and the projecting end of the strap must be inserted through the usual leather loop on the buckle section of the strap which may result in an unsightly appearance, and a curling of the end of the strap.

It is therefore an object of the present invention to provide a fastener for a wrist watch strap easy and safe to adjust on any size wrist and to hold the watch safely, securely and comfortably thereon. Even if the strap ends are not buckled or locked together, there is safety against loss or breakage, and a neat appearance throughout the. life of the strap is obtained.

The elements set forth comprise a construction which is simple, economical to manufacture and ornamental in its nature. It is also very easy to operate on the wrist of the wearer and comfortable when worn, there being no projecting parts to press against or bruise the skin.

These advantageous objects are accomplished by the novel and practical construction and arrangement of parts hereinafter fully described and shown in the accompanying drawing, constituting a component of this disclosure, and in which Figure 1 is an edge view of a wrist watch band made in conformity with the invention.

Figure 2 is a plan view of the same.

Figure 3 is a fragmentary sectional View taken on line 3-3 of Fig. 2 and drawn to an enlarged scale.

This device consists mainly of two straps, 5 and 6, of suitable thickness, preferably of 1921. Serial no. 533,403.

soft, high grade leather, ornamented if desired on their-outer surfaces and smooth on their inner surfaces which contact the wrist.

At the opposed outer ends of each strap are hollow bars 7 and 8 which provide the usual means for connecting with the frame of a watch casing, as clearly shown, these bars being formed with rearwardly extending clamp members between which the strap ends are firmly secured. Sewed loops on the said outer ends could alsobe employed, if desired.

The strapb contains acentral row of perforations 9' spaced apart, and has fixed on its opposite end a clasp 10 in which is pivoted a loop 11 closely encircling the adjacent strap 6, acting as a loose keeper for it.

On the end of the strap 6 is secured a clasp 12 in which is pivoted a leaf l3 provided-with a bent hoolgl l adapted to be selectively en-' gaged many of the perforations 9 of the strap 5 thereby to lengthen and shorten the operative length of the band at will.

The hook 14 is constructed with a hinge at 13 to permit of the easy removal of the hook from engagement with the other'strap,the relative length of the hook-the bend-and the point of turning, all being important factors in obtaining a proper operative arrangement.

As stated above, my invention provides a measure of safety against loss' or breakage of the wrist watch even though the strap ends are not secured together by insertion of the hook 14 in one of the perforations 9. Because of'the proportioning of the loop- 11 and the hook 14:, it is impossible forthe Strap ends to be separatedby pulling the loop 11 overthe'hook 14. Hence the straps 5 and 6 are at all times secured together, and the wrist watch cannot be removed from the wrist except by passage of the complete band over. the, hand.

,Although the foregoing is descriptive of the preferred embodiment of the invention, it will be apparent that minor changes may be made in its construction, without the exercise of invention or conflicting with the scope of the claims hereto appended.

Having thus described the invention, what ice is claimed as new and desired to secure by Letters Patent, is

1. A fastener comprising a pair of overlapping strap ends, a loop pivotally secured to the end of one strap for receiving the overstrap, said loop-carrying strap having a cen tral roW of spaced perforations, and a hinged hook member on the inner end of the said overstrap adapted to be selectively engaged in any of the said perforations.

2. A fastener comprising a pair of overlapping strap ends, a loop pivotally secured to the end of one strap to receive and slidably engagethe overstrap, said loop-carrying strap having a series of longitudinally spaced perforations, a clasp on the inner end of the overstrap, a leaf pivoted in said clasp, and a re-entrantly turned hook on said leaf for selectively engaging said perforations,

the re-entrant portion of the hook extending a suflicient length to prevent accidental disengagement during use.

3. A fastener comprising a pair of overlapping strap ends, a loop pivotally secured to the end of one strap to receive and slidably engage the overstrap, said loop-carrying strap having a series of longitudinally spaced perforations, and a re-entrantly turned hook pivotally secured to the inner end of the said overstrap adapted to be selectively engaged in any of'the said perforations.

4. A fastener comprising a pair of overlapping strap ends, a looppivotally secured to the end of one strap to receive and slid- 5 ably engage the overstrap, said loop-carrying strap having a series of longitudinally spaced perforations, and a hook pivotally secured to the inner end of the said overstrap adapted to be selectively engaged in any of 49 the said perforations, said loop and said hook being so proportioned as to prevent said straps from being separated at their inner ends.

5. A fastener comprising a pair of over- 45. lapping strap ends, a loop pivotally secured to the end of one strap to receive and slidably engage the overstrap, said loop-carrying strap having a series of longitudinally spaced perforations, and a re-entrantly 50 turned hook pivotally secured to the inner end of the said overstrap adapted to be selectively engaged in any of the said perfora-w tions, said loop and said hook being so proportioned as to prevent said straps from being separated at their inner ends.

' In testimony whereof I have hereunto affixed my signature.
