When the clasp is contracted and the foldable members positioned in over-lapping contacting relation as shown in Fig. 4 they are retained in fixed relation by a latch member 2| mounted in the cover member II and engageable with a ward or detent 22 on the bottom member I3. `The latch member 2I is integral with one end of a springarm or finger w23, the ,opposite end of the arm beingfastened` at 24` togend25." of the cover member II.

As shown in Fig. 6 the latch 2| on the spring. arm or tension member 23, when in its normal position, engages the ward 22.

2| automatically causes the arm to move laterally.

permitting the latch to snap over` the detent'22` By reason of its resiliency the spring arm 23 carrying vthe latch 5. From the foregoing it will be evidentl that by reason of the present automatic locking relation between the lower foldable member I3 with the cover member II, the members when in closed when the foldable members-'are pressed intol" i folded relation. For the purpose of releasing they members, are released and Opened as shown in latch, the spring arm 23 is provided with a vfinger piece 26. When the iingerpiece is pressedin wardly the spring arm 23 is' moved to disenga'g'e the ward 22 and release "the members." `The releasing mechanism as shown y isi disposed fatl one' end of the members when folded .f` 4 Furthermore, it will be evident that by reason of the position of the releasing means the natural action performed is to compress the fingerl piece and at the' same time lift itto unfold taheniernbers.

The positionof the lreleasing means" therefore facilitates the opening or unfoldin'g'ofthe vfolded members thus facilitating and fsimplifyingjthe operation of expanding the. clasp.. The location of the releasing means at one end of. thecover member is accomplished as shown Vby hingedly' connecting the end I6 of .the ,intermediatezrnemf ber at a. point oILthecovermernber removed' from end I'I thereof. j .This makes possible the disposition of the finger piece .26 land latch` 2| between-theend .I6 of the intermediatemember and the adjacent end I1 of the'cover member. I. As shown more clearly in Figs. 4, 'l and tlieltop wall of the coverinember. is 4extended and bent to form. end I'Ifi'nto a tubular housing or guide for the finger piece' 26. Thus the..fingerpiece 26 isnlocated at `the end ofthe .cover memberi I.. Thereforewhen the finger piece is movediendwise in opposition vto spring; 23 to actuate the latch and.

release the folded members, the location off. the finger piece at the extreme end of the cover mem- .folded relation maintain the pawl 3| in contact with the teeth 3 3. On the other hand immediately upon actuation of the finger piece 26 the clasp ktherefore immediatelyjexpands to its fullv extent permittingthe removal ofthe bracelet over the hand.

Y ,When the clasp is used as a connector for a Wrist watch bracelet, for example, it may be readily openedlto its fullest extent permitting the free passage of the hand 1.70 position the .bracelet The foldable members may then be contracted to their folded relation whereupon the latch 2| automatically-engages.the detent or lug 22 to hold the partsagainst separation and closed .relation ofthe membersjI'I vand I3 mainy tains` the pawl 2| engaged with teeth 33.'.

relation the cover member II and thebottom member I3'form a substantially smoothoutsid surfaceof the'members when closed.

In clasps ofthe 4present type it is desirableftoA The member -'I3 isof such dimension as vto be received between inturnedf-ends `2I|'and 20' so that when the foldable membersare 4in folded` sirable the bottom member. I3 may be provided with raised portions 34 and 34' vto frictionally engage the edges of flanges 20 and 20' to hold the end 25 of the cover and end I9. of ther bottom member in firm relation. inasmuch as the foldable members are positively locked the duty imposed on the friction means is negligible. l When the bracelet is appliedto the wrist and the foldable members, closed as above explained the slidablemember may then be moved inwardly to causeits pawl 3| to engage teeth 33, the operative relation between the pawl andteeth being .effected by reason of the latching .means which firmly holds the members ,in fixed relation. The bracelet may therefore be adjusted by moving the slidable member inwardly until the bracelet ts the wrist vto the satisfaction of the user.

As above set forth aslighi'l pressure on the finger piece 2E immediately releases the foldable members as well as the slidablemember permitting a free and convenient removal of the bracelet.

The present invention therefore provides a simple and eii'ective clasp or connector which may be quickly and conveniently contracted to lock the members againstunfolding and at the same time putting the slidablemember into operative condition.

lv Although a preferred embodiment of the invention is shown-and-.described'herein it is to be understood that modifications rmay be made therein without departing from the spirit and end of said cover member, said end of the cover member having the top wall extended to provide a. tubular housing open at one end, a latch member mounted in said cover member and positioned between said hinge and said housing, a spring member for normally urging said latch member in a direction transverse to the longitudinal axis of said cover member, a bottom member having one end hingedly connected to the other end of said intermediate member, a detent `in adjacent spaced relation to the other end of said bottom member for engaging said spring actuated latch member when the cover, intermediate and Ibottom members are in folded relation, a movable member disposed in and extending from the open end of said housing to provide a linger piece for actuating said latch member to permit the folded members to be unfolded.
