The invention; relates .to improvements in Clasps such as those used onbracelets and necklaces, and it is one object of such inventionto provide a novelfo'rm of clasp in self applied catch-means ,for engagement r d a ela-5p f s l a in x e s e y efficient and desirable construction.

I Wit th te ine' in v w, t in ee tion resides in the .novel subject Inatterhereinafter described and c laim'ed, the descrip q f g.siipplen ente l b gh m ins-d awin si F1gure1'1s a plan ,VlESV of a clasp constrncted inaccordance with the invention.

4 Figure ;2 isa central longitudinal section online2 2' of Fig, 1. j Figure 3 is a longitudinal sectional view t a dif e en P n a indicated by li 3+3 or Fig. 2.

1 Figure 4 is a view similar to'Fig. 3 but showing the twos'ections of the clasp separated from each other.

Figure 5 is a sectional view on line 5-5 of Fig. 4.

Figure 6 is a perspective view of the catch releasing device.

The drawings above briefly described, illustrate the preferred form of construction, and while this construction will be hereinafter rather specifically described, it is to be understood that within the scope of the invention as claimed numerous modifications may be made.

' The numeral 7 designates a sheath forming one section of the clasp, the other section 8 being provided with a spring metal plate 9 for insertion into the open end of the sheath 7, this open end being designated at 10. Near the other end of the sheath 7, the latter is provided with a shoulder 11 which faces in a direction away fromv the open end 10. This shoulder may well be formed by increasing a portion of the thickness of one of the side walls of the sheath, the relatively thin and thick portions of this wall being designated by the characters 12 and 13 respectively. If desired, the thin wall portion 12 may have a slot 14: coincident with the shoulder 1l, ;but this is not absofv lately essentia :The plate '9 is stampedto provide witha' lat l isti eeat h-les1 5, wit a h of spring {linger-s16 proj ecti ng 'beyondfaml d spe ede th epr i e ed f said as and with a spring tongue the latter .beii'ig bowed from the plane of the plate, in the opposite direction from the direetiql in which the lug '15 projects. The plate 9 also formed, at the end thereof adjacent the remainder of the section 8, witl i,.opposite P e t ng gs 0 ears as fecei i i notches 19 in ,the edge walls of the sheath 17.-

' .Ext adt agar releasing the catch lug 1,5, said shaft be ng preferably fiatand being interposed between the lfingel'igs 16l an' dlt-he .wall ,pqrtion 12, with the fingers bearing on 'saidshaft when the two sections of the clasp are interengaged, as disclosed in Figs. 2 and 3. As soon as this shaft is turned however to the position of Fig. 5, it lifts the fingers 16 sufficiently to disengage the lug 15 from the shoulder 11, thus permitting the plate 9 to readily slide from the sheath 7 I The shaft 20passes through openings in the edge walls of the sheath 7 and is pro vided at one end with a suitable stop 21 which prevents withdrawal in one direction from said opening, the other end of the shaft being provided with an operating arm 22 which, when the two sections of the clasp are interengaged, extends longitudinally at one edge of the sheath 7, this arm being provided with a hook 23 which then engages one of the cars 18. Thus, the arm 22 and the hook 23 serve to connect the two sections of the clasp, and said sections are also con nected by engagement of the lug 15 with the shoulder 11. Thus, a positive lock is provided which effectively prevents accidental disconnection of the two clasp sections. When hook 23 is engaged with one of the cars 18, one flat side of the shaft 20 is then g, across thesh th'l, is a shaft The fingers the tongue 17,

incontact with the fingers 16, so that the lateral pressure exerted on the sheath 7 by causes the fingers to yieldably hold the shaft in this position and consequently retains the arm 22 in such position that the hook 23 will remain engaged with the ear. When the clasp is to be released,

the arm 22 is swung to a position at right angles to the plane of the sheath 7 so that its hook disengages from the ear 18 and at the same timethe shaft lifts fingers 16 and effects the disengagement of the lug 15 from the shoulder 11.

The device is exceptionally simple and inexpensive, yet will be efficient, reliable and in every way desirable. On account of these existing advantages, the details disclosed are preferably followed. However, within the scope of the invention as claimed, variations may be made.

I claim L'A clasp comprising two sections slidably engaged with each other, self applied.

catch means on one section engageable with the other section, a rotary releasing device for said catch means mounted on one section,

' said releasing device having a portion engageable with the other section to constitute an additional tie between the two sections, spring means for holding said catch means in operative osition, said spring means including a memberv engaging said releasing device to yieldably hold the latter in engagement'with said other section.

2. A' clasp comprising two sections slidably engaged with each other, self app ied catch means'on one section engageable with the other sectionpa rotary angular rod mounted in said other section for releasing said catch means, spring actuatedineans,

engaging said rod to hold' it yieldably in operative position, said releasing rod having a gaged by a portion of said plate,an operating arm for said shaft disposed at the exterior of the sheath and normally extend ng longitudinally of the latter, and a lateral ear on said plate projecting to the outer side Y of said sheath, said arm having a hook portion engaging said ear.

4. A clasp comprising a sheath having an open endand a shoulder facing away from said end, a plate insertable into'the sheath through the open end thereof, said plate having a lateral catchl ug and spring means for engaging said lug with said shoulder, and a releasing shaft for said catch-lug, said shaft extending across said sheath in position to laterally move said plate to free the lug from the shoulder when the shaft is rotated, said shaft having an operating handle at the exterior of the sheath. r
