This invention relates to improvements in clasps :for attaching metal wrist watch bands to Wrist watches.
Anobject of this invention is -to provide ta device for attaching imeta'l Wrist watch bands to wrist watches, that can be easily secured to and readily vremovedmfrom wrist watches.
Another object of-thisinventionis'to providea device, as stated above,ithat utilizes the band as a T locking means to prevent inadvertent disassociation of the band from the wrist watch.
Another object of :this invention is 'to provide a device for attaching.- a. wrist watch band to a wrist watch that is inexpensive-to manufacture and which presents appleasing and attractive article when complete.
"These and other objects are attained'by the means described herein and disclosed in the accompanying drawings, :in which:

*Fig. 6 is a sectional view taken on line 6-43 of Fig. '5.
Fig. 7 ,is a sectional 'view' taken on line 7-"7.-of' Fig.
The improved-clasp of this invention is of that type which is secured to wrist watches and allowed to remain secured for months or -years, it'being necessary to remove theclasp from'fthe watch only at such times that it is necessary to -repai'r or 'cleanthe-watch, or replace the" band.
The clasp 10 is used to attach one mem- "ber-of-a sectional-wrist watch band to a-wrist watch. A-wrist watch 'bandcomprises two members such as 11. The free ends 13 of the members 1 1 are provided with complementary means for detachably connecting such ends together. The herein disclosed invention is concerned with the attachmentof the members with the opposed sides of a Wrist watch.
Each clasp 10 is of a hook-shape-and comprises a pair of arms 15 and 16 of unequal length. The way 17 between the arms 15 and 16 receives a-bar or post 18 carried by arms 19 and 20 extending from the Wrist watch case 21. :The-arm l5'of the clasp is provided with an abutment 22, struck inward from the body ofthearm 15. An elongated perforation 23, extending laterally of the arm 15, isformedintermediate the abutment 22 and the remainder ofthe arm 15. The band 11 of spring steel or other metal extends through the elongated slot 23. The end 27 of the band adjacent bar 18 onthe watch, is bent upon itself to provide a double thickness of the band underlying the arm 15. The band is bent upon itself at'25, such p,or tion. having spring characteristics. When the band is in its operative position, the looped end of'the band is received in the way 17 and prevents the bar 18v from passing therethrough. The forward end 26 of the overlapping finger 27 of theband contacts the abutment 22 and prevents the disassociation of the wrist watch from the clasp 10.
The body of the arm 15 may be provided with a perforation 28, which may communicate with an elongatedperforation 29 formed in the band 11. It will be noted from Fig. 2, thatthe perforation'28 and elongated perforation 29 are in alignment, whereby the finger 27 of the spring may be seen from the outside. Vhen it is desired to remove the band and clasp from the watch a pin or the like 30 is inserted-through the perforation 28 and elongated perforation 29 and pressure is applied to spring the forward edge 26 of the band beyond the abutment 22 as shown in dotted lines in 'Fig. 2. Thereafter the band may be moved to the right and leaving the throat of the hook between the arms 15 and 16 unobstructed so that the bar 18 of the wrist watch may be withdrawn from the way 17, as shown in dotted lines in Fig. 3.
The modified structure shown in Fig. 4 comprises a hook-like member 14 and a band 11 having one end of band bent upon itself to provide an arm similar to the finger 27. This modified structure, however, comprises a lug 31 that may extend beyond the body lines of the hook member 14 to facilitate projection of edge 26 of arm 27 beyond abutment 22.
The modification shown in Figs. 5, 6 and 7 may comprise a pin-like member 32 carried on a lug 33 formed on the clasp arm 15. The lug 33 may have spring characteristics, dependent upon the character of metal from which the clamp 14 is made. Normally the lug 33 holds the pin 32 in such position that by depressing the lug, the pin functions to project the end 26 of finger 27 beyond the abutment 22.
In this modification the abutment 22 is formed by bending a pair of ears 3d and 35 upon the body of the clasp arm 15, see Fig. 7, thereby providing a way 36 between the ears 34: and 35 and the arm through which the band extends. It should be noted that this abutment structure may be used with either of the other clasp structures.
In assembling the band 12 with the clasp 10, the end 26 is sprung away from the band and passed through the elongated perforation 23 until the abutment 22 reaches the loop or eye in the band. Whereupon, the band is rotated about the abutment 22 and the band passed further through the elongated perforation 23 until the edge 26 of the arm 27 contacts the edge of the abutment 22 and the loop or eye of the spring closes the way or throat 17 in the clasp 14.
.Vhat is claimed is:
1. In a device of the class described the combination with a wrist watch having a bar extending therefrom, of a hooloshaped memher having arms and a way between said arms, the way adapted to receive the wrist watch bar, one of the arms being provided with an elongated perforation and an abutment. a band extending through the elongated perforation and having one end bent upon itself to form an abutment on the band in alignment with and normally contacting the abutment carried by the hook-shaped member, means carried by the band for normally closing the way between the arms of the hookshaped member to prevent detachment ot the wrist watch bar from the hook-shaped member, and means for disengaging the abutments from one another whereby the hook-shaped inen'iber may be disassociated from the wrist watch.
