SNAP-FASTENER.

Specification of Letters Patent. 'Pgmtgntgd Sept '7, 15220,

Application filed January 14, 1914. Serial No. 811,971.

To all whom it may concern v Be it known that we, ELIZABETH J. SMITH and DOUGLAS SMITH, both citizens of the United States of America, residing in Larchmont, in the county of Westchester, and State 3 of New York, have invented certain new and useful Improvements in SnapFasteners, of which the following is a specification.

This invention relates to separable fastenors, more particularly snap fasteners, and aims to provide improvements therein. The

present invention provides a pronged device. which may be cheaply and simply manufactured, which iscapable of being applied to fabrics, and particularly to light fabrics such as are used for ladies dresses or the like, in such manner as to be securely attached thereto without mutilation of or damage to the goods. The fastener. is als'o'one which is capable of being applied to goods with, great rapidity, and either by. hand or by use ofa machine.

Figure 1 illustrates a sectional view with the parts in united position. Fig. 2 is a bottom plan view of. the parts shown in Fig. 1.

Fig. 3 is a sectional view of the socket member illustrated in Fig. 1. I

Fig. 4 is a top plan view of the said socket member.

Fig. 5 isa sectional view of the ballmember'illustrated in Fig. 1.

Fig. 6 is a top plan view of said ball member.

Fig. 7 illustrates further an embodiment of the invention, a top plan view of one member being shown.

Fig. 8 is a view similar to Fig. 7, illustrating a still further embodiment of the invention. i

Fig. 9 is a top plan view of a socket member, with parts shown in section, illus trating a further embodiment.

Numeral 1 designates the base piece of the fastener member; 2, the socket part; 3,the

ball part; and 4, the prongs.

The fastener members are preferably formed of sheet metal, and the ball and socket formed by appropriate metal-working op erations.

Furthermore, in order that the goodsmay liens fiat as possible over the ball'and socket members, they base part of the fastener may i be bent bac'kwardly'or upwardly, toward the back of'the socket, as shown in Figs. 1 and 3. From Fig. 1 it will be seen that the goods are brought relatively close-together by the fastener, it being understood thatthe proportions are considerably exaggerated in the drawing. g

In order to obtain a resiliency 1n the ball or socket, or both, the ball orsocket, or both.

may be made with portions out out there from as indicated at 5. V

The prongs 4 are preferably formed by tener, and preferably of the metal of the base piece. .The cut out portion of the metal which is left after cutting out the prongs 4 may constitute'the cut out portions 5,-which are provided in the ball or socket, or both. V In order that the pronged fastener may be attached to fabrics, and especially to light fabrics, in such manner as to be firmly and securely attached thereto, and without local} izing the strains transmitted by the fastener to the goods at the bends of the prongs, it is desirable that the prongs should clasp the goods between themselves and the firm part of the fastener member or base piece. It is also desirable that the prongs shall overlap close together upon the face of the goods. 7 The prongs 4, are, for the foregoing considerations, preferably formed somewhat long, narrow and tapering, and with a flat side adapted to be pressed against the goods. A fastener member or base piece is also provided with firm portions 7 against which the prongs are adapted to be pressed when turnedover against a piece offabric to which the fastener is attached. 'Asshown n Figs. 1 to 5 inclusive, the portions 7 lie between the cut out portions left after cutting out the prongs 4, and the'pron'gs are pressed against cuttin them out of the metal of the fasthe portions 7 by turning them to one side in bending so that they will lie'to one side of the base piece, as shownin Fig. 2. This may be accomplished'by hand or by a suitable machine, as above stated.

1 The spring 1s In Fig. 7, prongs are shown as cut out of the marginal portions of the base piece. In

this construction the prongs are turned back upon themselves upon theportion 7 of the base piece, which portion 7 lies opposite the portions of the base piece from which the prongs are out. By this construction the prongs may be made to overlap, without being superimposed, upon the face or the goods.

In Fig. 8, a member is shown wherein the prongs are cut out of .the metal beyond the edges of the base piece. As shown, the prongs on op osite sides of the fastener memher are pre erabiy slightly staggered, in

order that the prongs when bent over on the base piece may lie side by side without being superimposed upon one another. The base piece may be slit at points Gin order that the prongs may have a straight bend.

A socket member having resilient means for retaining a ball member therein may be manner as not 4, when turned against the solid portion 7 of the base piece.

shown in Fig. 9 at 9. The

Such a spring is place by a bent-over spring may be held in the head of a lug 10 struck up from the metal of the basepiece. I

- The invention is capable of receiving other embodiments than those illustrated.

hat is claimed is w 1. is member of a separable fastener having prongs thereon, a projecting socket-piece, a spring attached to said fastener and having parts adapted to project through said socketpiece to engage a'ball-member when inserted in said socket-piece, said fastener member having a base-portion against that face or" said base portion from piece projects.

2. A member of a separable-fastener having prongs thereon, a projectingsocket-pieee, a spring attached to said fastener and having parts adapted to project through said socketpiece to engage a ball member when inserted in said socket-piece, said fastener member having a solid'base-portion against which said prongs are adapted to be pressed, said spring being out of the way of said prongs when said prongs are pressed against the solid-portion of said base-piece.

In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.
