FILED JULY29. 1922.

Patented Jan.. 9, 192235@ naiven si JEWELRY CLASP.

Application filed July 29, 1922. Serial No. 5'TS,299.

'To all'whom t may concern.'

13e it known that ll, lsimnn il. Posner, a citizen oit lthe llnited Icitati l residing at Providence, in the county et fll'rovidence and State ot Rhode island, have invented certain new and wul improvements in Jewelry Clasps, of which the tollowiug' is a specifi cation." I

lily invention relates to jewelry clasps and has for its essential objects the secure intercnc'agement ot the two members ol the clasp to avoid accidental separation; and the attainment ot this end in a simple and inexpensive structure.

I lo the above ends essentially my invention consists in such parts and in such combinations ol parts as :tall within the scope ot the appended claims.

lin the accompanying drawings which lorm a part ot this specification Figure 1 is a reverse perspective view or a clasp embodying my invention,

Figure 2, a section of the same on line 2--2 of Figure l, and

Figure 3, a section on line ure 2.

Like reference characters parts throughout the views.

ln the form of my invention herein shown the clasp comprises front and back plates 5 and 6 respectively of oblong` curved shape fastened together by transversely disposed partitions or supports l provided with centrally disposed oblong' slots 8. The back plate has at one end a cavity 9, and in longitudinal alignment therewith a perifere-tion il and a hole l2.. The perforation is intermediate the cavity and the hole. lin this instance the plate at a point in the margin oil the hole has a bevel i3 forming a bevel edge or lip les., ,fait one end oit the iront plate 5 is a longitudinally disposed lug or bearing;- lb extending' centrally the cavity 5l oli' the plate 6. llast in the lug 'i6 is a pintle lf3, The lup 'lli is rearwardly enteurled to torni an attaching ring or eye 20. lli ilat arm 22 normally restingv against the outer tace of the plate 6 has rearwardly directed inclined bearings or perforated ears Z-fl engagging the pintle.

A. catch plate or member comprises an apex portion 27 and diverginfg arms 28 having enlarged free end portions or heads 30 provided with lateral serrations 3].. @ne oi' the heads 30 is extended forming a portion 333 provided with a perforation 3d to 3--3 of Figindicate like catch.

will be observed'that the divergence ofthe arm 28 forms a resultant l! shaped longitudinal opening' 4l() inthe plate. The plate is cut from thin sheet metal and the arms 28 have a degree of lateral resiliency.

lioose in the hole 39 and in theiperforation l is a post il upon the 12. A second p ost 43 tast to the end ot the arm passes through the hole l2 and into the slot l0 in contact with the arms 28. Near its base the post, or pin i3 has a lateral recess Ll5 to receive the bevel edge l/l.

ln operation the receiving member ot the 'traine comprising` the front and back plate and supports is adapted to slidably receive the catch member. ln unlocked or disengaged position. the arm 22 is manually swung away from the back plate, freeing the latter of the posts il and 43. The catch is now insertable into the receiving' member by cont pressing the portions 30 with the nails ot the thumb and linger, and the l catch `slides through the slots S 03'. the supports i".

llfhen the lull distance of insertion is reached the shoulder 37 snaps into engagement with the rear face of one oli the supports Si and alords a means of retaining` the Finally the arm 22 is manually pressed back into the originally described position. The post now 'forms a firm auxiliary locking; means which is capable oi successfully meeting` any unusual strain-not supportable by the shoulder 37. and is eliec- Lp-r c..

"tive it the shoulder 3.7 fails to operate. The

latter contingency is remote because the post il occupies the entire width oi4 the slot l() and, like a wedge, torces or maintains the arms 28 distended effectively even after rcpeated use lessens the resiliency o'l' the latter. The lip 14 cooperates with the notch 45 in thc post to insure that the plate be not accidentally moved away `from the back plate.

This clasp is especially adapted for use with articles ot jewelry, including, necklaces. circlets.. bracelets, bead strings, and the like.

l claim:

l. llna liewelry clasp, Ya casing provided with an open end and with a hole, catch plate insertable into the easing: through said end including diverg'ing; resilient arms, an

arm pivotally mounted upon the opposite; end

of the casing, and :i post on the pivotal arm movable through the hole and between the diverging)r arms and in contaot with the latter.

2. In a jewelry clasp, a casing provided with an open end and with a hole, a catch plate insertable into the casing` through said..

end Comprising dii/erging resilient arms and e lateral shoulder on one arm engagea-ble with the casing', an arm pivotally mounted on the casing, and a post on the arm movable through the hole and engageable with adjacent edges of the resilient arms.

3. In a jewelry Clasp, a easing provided 15 with an opening in one end and With a perfoi-ation and with a hole, a oatoh plate insertable into the casing through the opening comprising an apex position, diverging resilient operating arms, and a shoulder on one of the arms, an arm pivotally mounted on the other end of the easing, a post of the last mentioned arm engageable with the apeX portion through the perforation, and a seoond post on the pivoted arm movable through the hole and engageable With the operating arms between said operating arms.

In testimony whereof I have affixed my signature.
