SNAP-FASTENER SOCKET AND TOP.

Annlication filed March 23,

To all whom it may concern:

Be it known that I, ABRAHAM H. BAUM, a citizen of the United State-s residing at Baltimore, in the State of Maryland, have invented a certain new anduseful Im- Tops, of which the following is a full, clear, and exact description.

One main object of this invention is to provide a snap fastener socket for use especially on textile fabrics, and more particularly knitted goods, such as mutllers, and other elastic fabrics, where owing to the tendency of the goods to stretch, it is difficult to apply the socket so securely as to prevent it from pulling out of the goods.

In those sockets or snap fasteners where a hole has to be made in the goods for the attachment of the fastener, the perforation of the goods serves to increase the tendency of the fastener and goods to part or separateunder strain. If the goods were carried bodily intact into the fastener cap by the application thereto of the attaching device, a certain clum'siness would result, and more or less difficulty encountered in setting the fastener. To avoid these several objections, and at the same time to provide a fastener Whose hold 011 the goods will be sufliciently the fastener in place under ordinary strains of use, I provide a cap having an interior riveting plate, made with a centrally arranged concavo-convex projection which is centrally perforated from the convex side so as to avoid a sharp cutting or shearing edge at that place, and thereby permit the goods to be stretched and carried up more or less intact into the cap by the cap-attaching socket of peculiar format-ion, so that the goods are gripped between the cap and the tip of the nipple of the socket. and also between the edge of the hale in the riveting plate and the base of the nipple.v and also between the hack of tae cap and the flange of the socket. all as .l will proceed now more particularly to set forth and finally claim.

socket. Fig. 5 is a cross-section of the cap or top and the socket assembled or set upon a piece of goods. Fig. 6 is a top plan view of the fastener attached and with its cap or top cover-piece removed. Fig. T-is a bottom plan view of the attached fastener. Fig. 8 is a bottom plan view, ona larger scale, of the riveting plate detached, and Fig. 9 is a cross-section thereof. Thesocket proper, which is also theattaching medium, is designated 1, and is shown in detail in Figs. 1, 4 and This socket comprises a base flange Q, a barrel 3 rising from the base and constituting the stud-engaging and receiving member. a

- shoulder at and a relatively wide nipple 5 rising from this shoulder. It is of prime importance 1n this invention that neither the nipple nor the shoulder should have edges which would cutor break the goods and hence these parts are rounded off and smooth. The result is that the nipple simply displaces the threads of the goods where they are parted at all and stretches and carries the goods along with it as it enters the cap or top.

The cap or top comprises a cover 6, a collet 7, having arounded and smooth back, an anvil 8 and a non-shearing riveting plate ll, these parts being held together by closing the cover over the collet in any ordinary way. The riveting plate is of peculiar and novel formation, and consists of a circular piece whose extreme outer edge 10 is substantially fiat, with a central concave-convex projection 11 provided with a central hole 1.2. In order to avoid a shearing edge or bur on the convex side of this plate where the nipple enters, I punch the hole through from this convex sidein the direction of the concave side, and thus leave a relatively smooth surface. Furthermore, the hole 12 is enough larger in diameter than the nipple to avoid a crushing, cutting, or shearing action of the nipple and the holcs edge on the goods carried by the nipple into and throughthis hole in the act of setting the fastener upon an article. Thus, while the goods are stretched, they are not. designcdly or desirably crushed, cut, or sheared, but are carried up substantially if not quite intact.

In the act of setting the fastener. the cap placed upon one side of the goods 13 rivetin and the socket piecezipiaced oppositev to it .on the other ,side, in suitab letools, and res sure exerted to force the two together, so that the nipple enters the hole 12 'inthe plate and the edge of the hole rests upon t e shoulder 4, and then; by'further pressure the riteting plate recedes within the top. and flattens out, as seenin Figs. 5 and 6, and the tip of the nipple 'ineeting the anvil 8', said nipple is more or less broken down so as to .grasp the riveting platebetween itself and the shoulderA, withthe goods gripped between the tip ofthe nipple and the anvil, and between the riyeting plate, and the shoulder, and between the fiange2 and the eollet or back of the cap, as shown in Fig. 5. As indicated in Fig. 6, which is drawn from a. specimen in actual use, the goods over the nipple a're substantially uncuta- A As shown in F ig. 5, the mouth 14 -of the socket is narrower than the chamber-above it, and the socket is rigid, and thus this form of the invention. isdesigne'd for use with a spring-stud; but obviouslythe invention is not limited tothis-oneform of construction,

The flattening out of the riveting plate9 is clearly shown in Fig. 5 and it is also shown how the body 3 of the at (aching device extends within the collet and up into the cap, As also shown'in Fig, 5, the construction-affords a very flat, comipact socket, especially suitable for, use on mu ers and similar wearing apparel. p H As shown especially in -Fi s. 5 and 7, by

'the construction described, tiebackof the goods is entirely clear of any broken threads; I "What I claim is:.

=51:- Aisnap fastener socket and top, said socket having a rounded and smoothnipple,

- perforated from its the shoulder and plate,

ed collet and a in this figure,

:1 barrel having a rounded and smooth shoulder, ,and'a base flan e, a rounded collet, and a riveting plate wit in the top, the said top closed about the plate and collet, said plate having a central concavo-convex projection convex side and thereby presenting a smooth non-shearing edge, so that when set the goods are rlpped between the socket and top at three places, namely, between the nipple and top, between and between the base flan e and collet without cutting out the goo s.

2. In a snap fastener socket and top, the socket member having a nipple provided with rounded, smooth and non-shearing edges, a' barrel having a rounded, smooth non-shearing shoulder, and a base 60 and flange, and the top member having aroundriveting plate arranged Within it, said plate provided with a substantially flat outer edge, a central concavoconvex projection, and a smooth edged nonshearing central hole of considerably greater diameter than the nipple, so that when the socket and topmembers are set the plate tends to flatten out, engages the socket member between its shoulder and nipple and said nippleis broken down, thereby grilpping the goods interposed. between t socket and top at three places, namely, between the nipple and top, between the shoulder,,nip ple and plate, and between the base fla e and collet, without cutting out the goo s.

In testimony whereof I have hereunto set hand this 22nd day of March A. I). 1911 I ABRAHAM H. GREENEBAUM. -Witne'sses:
