LINGEBE CLASP.

which the following is a eXact description, reference accompanying drawings.

full, clear, and being had to the This invention relates to lingerie clasps of the type wherein there is a metal strip carrying adjacent snap fastener adapted to hold U-shaped spring its free ends a the two limbs substantially parallel in Vuse but enabling their ready separation.

The present invention specific improvements shown in my Patent No.

on the involves certain structure 1,383,906, issued July 5, 1921. Its object is to cheapen the construction and at the same action, and this l clasp more certain in its accomplish by providing a snap fastener wherein time render the stud andv socket the socket member has an internal spring adapted to engage the stud, and by soldering inner face of one of the shaped spring. I position each member to the limbs of the U- the socket member and at the same time prevent the solder from passing into the interior and interfering with the spring by making a cavity in one of the limbs of the metal strip and setting the dome of the socket cavity.

This cavity -serves member in such to retain the solder so that the socket member is easily and effectively fastened in place.

The invention is illustrated in the drawings cally are summarized ln the drawings, Figs. 1

hereof, and hereinafterv described, and the essential features in the claims.

1n Figs. 1, 2 and 3, I have shown the body of the clasp as comprising two substantially parallel limbs and 11 and a bowed connection part 12. This body is made of spring sheet metal. One of the limbs, shown as the lower limb in Fig. 3, has

an intermediate portion 13 separated from the limb by longi tion of the dome. By

tudinal. slits and bowed upwardly to provide a spring portion, tending to clamp the fabric when the space within the clasp is filled. A suitable cavity 14 is provided in one of the limbs adjacent the end, being made by forming an outward protuberance coneentrio with the semi-circularly curved end 16 of the limb.

rlhe stud member 2O of the snap fastener as shown comprises a disk-like portion 21 having its eXtreme edge curled inwardly as at 22 and having centrally projecting from it a hollow stud 23 having an enlarged head and a narrow neck 24. rIhe base 21 of this stud member has substantially the same diameter as the width of the metal strip and is soldered to that strip with its outer edge adjacent to the extreme semi-circular end 17 of that limb of the body.

The socket member of the fastening comprises a sheet metal cup curled inwardly at its edge as at 31 and having centrally a hollow inwardly projecting dome 32, the extreme end of which extends beyond the plane defining the extremity of the inwardly curled edge. rThis dome 32 has an enlarged head portion 33 and a narrower neckportion 34. rlhrough opposite sides of the neck portion are slots 35. Within the socket member is a wire spring i0 shown as having a portion 41 extending circularly for somewhat more than a semi-circle, and then bending backwardly towards itself as shown atV 42, and then bending in the opposite direction to provide two free legs 43 which extend across the slots and project into the space within the dome member of the socket, as shown particularly in Fig. These springs are adapted to snugly engage the head of the stud member and give back as it is'forced into the socket and then by engaging the neck of the stud hold it effectively in place.

As heretofore stated, the end of the dome 32 of the socket member extends beyond the plane of the edge of the socket. The cavity 11i in the limb 10 of the U-shaped strip is adapted to accommodate this projecting porthis means the cavity automatically positions the socket member so that it may be secured in place with its outer edge substantially aligning with the semi-circular edge of the strip, the socket member preferably having a `diameter sub'- stantially the same as the width of the strip.

The soclet member is eiiectively secured in place by having its dome soldered to tlc strip, the solder for this purpose being` illustrated at 50 in F a. The protuberance of the limb l() provides very convenient means for holdingthis solder While it is molten. A small amount of solder is either i'irst secured on the end oi the dome or within the cavity, and then when the parts are in position heat is applied snlliciently to melt snch solder, the limb having the cavity being that time bel- W the soclret, and thus sii-ch protnberance forms on its then npper'side shallow cup to hold such molten sold-cr until it-cools and hardens. This niables the socket member, Which is openY as shoivn in 4' and has the internal spring, to be readily and YEectively soldered to the limb without danger oit the solder passing into the interior cil the socket and interif'ering` With tie Y' spring action.

My lingerie clasp may be very constructed, the fastening men'ibers being readily applied to the limbs. The clasp is neat in appearance and effective in service, thespring Within the socket member serving to retain the stud member therein even though the limbs-ot" the clasp embrace a considerable thickness oit fabric and applying corresponding' stress, tending to separate the lree ends at the slmner. Furthermore, by accurately positioning the parts ot' the snap fastener as described adjacent the free-ends of the strip, l am able to use a comparatively narrow strip Without requiring a smaller fastener than is commercially practicable.

'l havefiound that the metal bot may be made very conv nientlj.'v and tactorily of spring sheet brass, though metal may be employed ii desired. brass'is used l have found it very effect to secure the snap Yfastening members solder as heretofore explainet. However with other materials the parts might ii desired be secured by l'nazing or electrically Welding.

Having thus described my invention, .l claim:

l. A lingerie clasp comprising a F:.l-shapeil resilient body and av snap fastener comprisinga stud rising` from a base, and i socket member having an internal spring, said socket member and base being secured to the inner faces oit the limbs adjacent their free edges.

2. A lingerie clasp confiprising a l-shapcd resilient body of metal, a snap fastener coinprising a stnd rising from a base and :i soci-tet member adapted to receive the stud, said base and socket member being permanently united to the inner faces ot the limbs of thestrip adjacent the free-cdoes thereof.

on the i: face ot he limbs 'i removably securing them together, sind snap fastener comprisine a sind secured to b one liinb and a socket me' er secured to the other, the socliet member having an internal domeV adapted to receive the sind, said dome projecting beyond the plane ot the edge oit the socket member, and the correspondingv limb having a cavity to receive such projecting portion ot the dome.
