11 claims. (c1. 24-1z3) Myl present invention relates' to clasps for bracelets, and has particular reference to the construction of clasps for Wrist watch straps of the cord type.

It has been found desirable to provide simple catch mechanism for cord bracelets, which may be quickly fastened and unfastened, and which will lock securely. To this end, I have devised a catch construction which receives a loop formed in one section of a cord bracelet, and I have provided means for locking the loop in received position. I have further provided a simple means for adjusting the length of the cord bracelet to t the Vwrist of the wearer. 15 n With the above and other objects and advantageous features in view, I have devised a novel clasp construction more fully disclosed in the detailed descriptionfollowing, in conjunction with the accompanying drawing, and more specifically defined in the claims appended hereto.v

In the drawing, v

v Fig. 10 is an enlarged perspective view of same, and

the cord holding elements.

Referring to the drawing, the wrist watch is equipped with a cord bracelet 16 having two

portions

17, 18 secured'to the wrist watch by end hooks 19, 20, the two portions being releasably secured together by .a clasp member 21. The clasp member 21 includes a base 22 having a rear compartment 23 to receive the two ends of the bracelet portion 17, the walls of the compartment having aligned openings adjacent therear thereof to receive the pint-les 24 of the bent over end 25 of a lock plate 26, the edge of the end 25 having teeth 27 to detachably grip the two ends of the bracelet portion when the lock'plate is moved to the locking position; the end 25 is Fig; 11 is a horizontal section thereof, showing' slightly out of perpendicular to the body of the lock plate, to produce a binding effect when the lock plate is so moved.

A retaining tongue 28 is positioned at the front y of the base'22`, to receive the loop 29 of the brace- 60 let portion 18, which is formed as a closed cord;

a cover plate 30 is hinged to the walls of the -1 compartment 23, in rear of the lock plate 26, and has fingers 31 to resiliently and detachably engage the en'd of the retaining tongue.

The cover plate -is provided with a nail piece 32 to facilitate disengagement from the retaining tongue. The

bracelet portions

17 and 18 have .the usual holding bands 33 of standard construction. p

The above described construction forms an effective clasp for the watch bracelet portions, and provides a cover part -that readily lends itself to ornamentation. The length of the bracelet is quickly adjusted by lifting up the lock plate, and a further safeguard against accidental unclasping is obtained by moving the band 33 towards the loop 29. i

4 The cover may be dispensed with, if the clasp is formed so as to permit locking of the loop'29. 80 Thus, .see Fig. 5, the clasp 34 has a base 35 with a rear compartment 36 and lock plate 37, similarv to the compartment 23 and lock plate 26; a lock button 38 is positioned at the forward end of the base, the shank 39 being slender to prevent un- 85 due spreading of the loop 29. A novel lock band 40 is provided to slide over the cords of the bracelet portion 18, see Fig. 6, consisting of a shell or case 41 which has its upper portion spaced to hingedly receive a ratchet plate 42, equipped with teeth 43 extending inone direction. The lock band is thus slidable towards theloop 29, but is locked against backward movement until the plate 42 is lifted; the end 44 of the plate 42 is formed to resilientl-y contact the case when the plate is in lock position.

The clasp may, if desired, be formed in one piece of metal, composition, wood, or the like, as shown in Fig. 9. In this form, the clasp 45'has a rear retainer block 46 provided with spaced openings 47 to receive'the two ends of theA bracelet portion 17, these ends being tied after length p adjustment of the bracelet. The retaining button 49 is shaped as shown in Fig. 10, to better receive the loop 29 in locking relation; the rearwardly pointed'end 50 leaves so little room between the button and block that the loop 29 is substantially locked against accidental removal, as the fairly tight t of the bracelet will prevent, the unlocking backward movement of the loop;

. to safeguard the lock.

While I have described specic constructional forms of my invention, it is obvious that desired changes in the form and shape of the parts, and in their relation, may be made, without departing from the spirit and the scope of the invention as defined in the/appended claims.
