CLASP.

tisanes.

To all whom t may concern: Y Be it known that I, Enron J'. SWEDLUND, a citizen of the United States, residing at Williston, inthe county of Williams 'and State. of North Dakota,.have invented certain new and. useful Improvements in Clasps, of

which the following is a specification.

This invention relates to certain new. and

y*useful improvementsl in clasps or couplings,

well suited for neck-chains or other'articles of jewelry, butnot necessarily conned to the jewelry trade alone as it is capableof It vhasfor its *objects among others to provide a simple and neat .appearing clasp, composed of few parts, those readily assem- .bled, positive in their action vvand ;o`nstit ut ing a clasp which cannot be .unfast'ened by accident and ,which will in itself constitute a. i 'perfect swivel so that a chain attached thereto will not become twisted'. Itis easily operated, capable' of manufacture at -small cost.

y by suitable dies from 'tubing of different metals or materials, or may be cast or turned or otherwise formadas' may be found most f Otherobjects. and advantages f the invention will hereinafter appear and lthe novel features thereof will1bc particularlyv pointed out in thel appended claims.

The invention `is clearlyillu'strated in the accompanying drawings, 'which with the numerals of reference marked thereon, form a part of this specification, and in which- Figure lis a side elevation .of my im proved clasp.. Fig. 2 is a substantiallycentral'longitudinal section through the same. Fig. 3, is an elevation of theA inside sleeve.

Fig. 4 isan end view of Fig. 3,'looking the direction of the arrow. Like numerals of reference indicate like parts throughout thedii'erent views.

In constructing my .improved clasp A.or' coupling, I employ an outside'shell 1wh1ch maybe of any suitable material and conf tour, and struck up be dies or given the requisite form by any suitable means. Itis. shown as provided with an eye 2 for the i attachment of one end of a chainor, other ligament, according to the Vuse to which it is to be put. This outer shell hasya closed end. 3 and an open end 4, the bore or passage 5 leading from the open .end extending for substantlally'one-half of the length, or a little more, lof the shell, as seen in Fig. 2 wherev it is enlarged,` as seen at 6, the -vresultant ta` l' -Specicatieon of Letters Patent. application mea nay 25, i915. serial No. 30,346.

` rammed .iaiifeaiaie peredwall forming a shoulder 7, as seen clearly in 2.

8 is the inn`er sleeve formed preferably from .a .single piece lo f j sheet 'material stamped or otherwise given the requisite form, having longitudinal slits 19 extending for the greater portion of its length and the material at one end being doubled upon itself, as seen in Fig. 2, lto form anannular enlargement 10 which is substant-ially of the' same cross area as that of the shell 1. This end may or'may not have aconcavity l1 to receive th adjacent port-ion 'of the eye -or ring 12. on the locking member 13. The opposite end ofthe .sleeve is turned 'upon itself or otherwise cons ructed to form `the annular bead 14 which issevered by the slots 9 here'toreferred to.

The .lockingmember liasat its inner` end a. head 15. adjacent which is; an annular groove 16, seen clearly in Fig. 2. The inside wallofthe shell-is smaller at the open end and larger inside to accommodate the larger 'end or @bead-on the sleeve. The sleeve is made of `such size as to practically ]ust fit the opening in the shell, but by into the shell by a little pressure, owing-to the yieldingnature of the sleeve and when in position within the outerv shell it is 'free to slide a limited distance inA or out. When the loclring member 13 isfinserted in the sleeve, it will' carry tlie-sleeve inward as far as it can gaand spring it enough to allow the bead or liange 14 on the sleeve to rest in fthe grooverof the locking member and as the reason of its being slit in a multiplicity of i I places, as shown, it can be readily pushed locking member is .pulled outward the sleeve will be'carried along with'it until the bead or., flange 14.. on the inner end ,of the sleeve comes. in contact with the beveled wall of the vshell and finally against the shoulder 7 and cannot bezpulled out. The

'harder they pull on the locking member, the Aharder it` will grip. Tn Fig. 2 the parts are vlshown as .distended, with the bead or flange of the sleeve engaging the shoulder on ythe.

inner wall of the shell.

To unclasp orl remove the locking mem los ber, allv that is necessaryto do isto push the sleeveand locking` member into the shell so thatthe shoulderfl? of the sleeve comes in. contact, with the adjacent end wall 18 Iof thev .outer sh' lland then hold the sleeve and shell vtightly together and pull the locking memberfout. .This iS the only manner in which the locking member can be removed. It will be understood that when the inner 'sleeve is pushed in as just described, itsl inner end and its flange or bead 14 are forced beyond thel tapered wall of the-sleeve and into the enlarged space 19, as seen in Fig. 2, where the slitted portion of the sleevel is free to expand and allow the lockin g member vto be readily withdraw n It w1ll be evident that the inner sleeve and' the locking member are free to rotate within the outer shell, thus constituting` a swivel, so that a chain. attached thereto cannot become twisted.

Modificationsin details may be resorted to without departing from the spirit of the invention Lor sacrificing any of its advantages.

What is claimed as new is j In a clasp of the character described,

`an outer shell having a longitudinal opening with tapered wall and an annular'enlargement with resultant shoulder, a sleeve slidablein said shell and having a resilient bead at its inner end received in said annular enlargement andlengageable with said shoulder anda locking member slidable within the' sleeve and removable therefrom and havingat its inner end ahead and an annular groove adjacent thereto, said sleeve and locking member being swiveled within the shell; i

v2; In a clasp of'the character described,

an`outer shell having a longitudinal opening with tapered wall and annular enlargement said 'shelll and'having a resilient bead at its inner end received in said annular enlargement and engageable with said shoulder and a locking member slidable Within the sleeve and removable therefrom andhaving a'tits inner end a head and an annular grooveQ-adjacent thereto, said sleeve and locking member being swiveled within the shell and the sleeve provided with longitudinal slits.

In a clasp ofthe character described, an outer shell having a longitudinal opening with tapered wall and an annular enlargement with resultant shoulder, a sleeve slidable in said shell and having a'resilient bead at its inner end received in said annular enlargement and engageable with said shoulder and a locking member slidab'le within the sleeve and removable therefrom and having at its inner end a head and an annular groove adjacent thereto, said sleeve and locking member being swiveled within the shell and the sleeve provided with longitudinal slits, and a ange upon its outer end engageable with' the adjacent end of the sleeve.

In testimony whereof I affix my signature in presence of two witnesses.
