1l BY .17' la J2 ATTORNEY N vne'iren stares. PATENT'. oI-Flc'r-L4 JEWELRY-(2121171.51

Application filed .March To al?. whom. it 'may concern Be it known that we, ABRAHAM L. Einesorr and Criannns Brnnnauir, citizens of the `United States. and residentsot the city ot' New York, borough ot lllanliattan, in the county and State ol New York, `have iii-- vented certain new and useful lniprovenients in JewelryClasps, ot which the -following is afull, clear. and exact description.

' Among the principal objects which the 'present invention has in view are: To avoid the accidental separation of the separable parts of a class such as disclosed. and the consequent loss of the article with which. vit is associated; to produce a .neat and fin- 'i'shed appearance in the article, and to siniplify and strengthen the construction ot the parts ot the clasp.

Drawings.

taken as on the line 5--5 in Fig. 1.

The herein disclosed clasp is usually employed for fastening necklaces. Heretofore such clasps have consisted ol a barrel type wherein a spring latch has been inserted, the parts whereof open to engage the barrel member. A second type has embodied the more graceful ilat or box body. n insert correspondinlyv flat has been used, the sides whereof spring apartl to engage seine member in the box body. ln some cases a bridge has been extended from the box body to catch a .hook-like insert member, after the saine has been drawn from the box body. These forms of clasp have proved objectionable for the reason that in the first nientioned instance. when. as accidentally has occurred. the insertmember becomes .'detached. the separating portions ot' the latch, and parts associated therewith. have opened, with the result that the necklace has fallen and often been lost. The objection to the last mentioned construction has been that it is clumsy and has marred the appearance Speceatlon ci Lettersatent. Patented Sept. 14, 192() 1926. Serial No. 364,084.

ot' what otherwise is an article lof Vorna.- mental wear.

as seen in the drawings, the clasp is of the itiat, box-like form, and has an ornamental top 10. The top 10 is removed .from the bottom 11 very slighly, to torni a narrow space 12 therebetween. The top 10 and bottoni 11, are structurally united by snil posts 13, 1&,15 or 16, the .outer surf-a s whereof are'llu-sh with the edges of the top and bottom portions. y

The snap 1T is intended 'for insertion between the posts 15, with which in service the separable ends of the lsnap engage. The snap is elongated, and is constructed from resilient material, cut to U-shape. to form the channel 18. and an enlarged opening 19, that produces the yielding or resilient section 20.

' At the opposite or outer end of the snapt` l?. the link Q1 is fastened to one ot the sides of the snap, and preterably to that having the shoulders 22. T he ring 21 simulates in appearance a ring 23, at the opposite end of the clasp. andset up troni the bottoni 11.

Through the rings 21 and 23 are passed the eyelets 2l and 25 at the ends of the string Q6, on which beads or other ornaments are usually threaded. Adjacent the extremity of the opposite side of the snap 1T to that having the shoulders 2Q, is a nick 2T, adapted to engage one of the posts 15 when the snap has been fully inserted between the top and bottom of the clasp. In order to insert the snap 1T in the latch, the said snap must first be adjusted with reference to the post 16, so that the sides of the snap pass around the said post. This is accomplished by disposing the snap in a p0- sition substantially transverse the length of the clasp. This operation is assisted by the curved edge 28 of the end of the snap having thenick 2T. `The snap is then drawn until the post 16 is in the enlarged portion 19 ot the snap, when it may be s/wung around on the post 16 to press the snap lengthwise of the clasp. From this position. as shown in Fig. l, it may be moved to the position shown in Fig. 1, where the shoulders 22 en" gaffe the post 15 on one side of the clasp, while the nick 27 engages the post 15 on the opposite side.

lr" now by accident the snap 17 becomes disengaged from the post 15, and the strain on the string 26 be sufficient.- to draw the snap out of the latch, itwould only result inthe snap catching on the post 16 in the position shown in Fig. 4. To become totally disengaged o r separated from the body of the clnasp'rit would be necessary to tighten the string 26 suiiiciently to permit the snap 17 swinging to the position perpendicular to the lengthwise axis of the body of the clasp which would shorten the circlet of the string 26 more than in its regular service position, a condition .improbable if not impossible.

As seen best in Fig. 2 of the drawings,

- when the snap is inserted in service position within the body of the clasp, the inner end thereof rests between the posts 14 which serve to steady the snap 17 and to hold same in service.

Ola-ima.

l. An article as characterized comprising ay thin box-like body portion having parallel closely spaced top and bottom port-ions structurally connected by edge flush posts, two of said posts being oppositely disposed in paired relation; an elongated resilient hook-like snap,V adapted for extension between said paired posts, the free ends of said snap being provided adjacent the extremities thereof with shoulders for engaging said posts; and a third post intermediate said paired posts in spaced relation thereto, said third post being' disposed between the sides of said hook-like snap to guide the same when moved in and out between said top and bot-tom and for engaging said snap at the bend of the hook thereof when drawn from between said first mentioned posts.

2. An article ascharacterized, comprising athin box-like body portion having parallel closely spaced top and bottom portions structurally connected by edge fin-sh posts, two of said posts being oppositely disposed in paired relation; an elongated resilient hook-like snap, adapted for extension between said paired posts, the free ends of said snap being provided adjacent the eXtremi-' ties thereof with shoulders for engaging said posts; a. third post intermediate said paired posts in spaced relation thereto, said third post being disposed between the sides of said hook-'like snap to guide the same when moved in and out between said top and bottom and for engaging said snap at the bend of the hook thereof when drawn from between said first mentioned posts; and a ring mounted` on said snap extended from one side thereof` in line witlivthe opening between the hook-like sides of said snap for equalizing the strain on said snap.
