Specification of Ietters Patent. Application filed J'uly 1i, 191a. swarm. 778,482.

Patented Sept. 1, 1914.

To all whom it may, concern:

Be it known that we, LUES Rnrrnu and,

HARRY FULFORD, citizens of the United States, and residents of the city of Providence, in the county of Providence and State of Rhode Island, have .invented certain new and useful Improvements in Separable Fastoners, of which the following is a specifica-' folded outward near their middle portion and the periphery of said plates being rolled over the free ends of said fingers so as to yieldably retain them in position, whereby the head of a complemental stud may be readily passed into said socket and removably but firmly secured thereto.

The invention further consists in providing the outer, plate with a central opening and rolling the stock around said opening inward to provide a bead over which the outer member is rolled for permanently securing. the whole in position on the goods.

A further object of the invention is to' swage the stock of the fingers slightly inward at a point between the base and the bend thereby stiffening the stock of the fingers and providing a contracted neck portion through which the head of the stud must, pass to enter the enlarged portion within adapted to receive it.

With these and other objects in view, the

inventionconsists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

Of the accompanying drawings: Figure 1 is an enlarged sectional elevation showing the socket member ermanently secured by means of the cap to t e material or goods and the stud in position to enter the socket. Fig. 2 is a plan view showing the shape of the-blank from which the socket member is formed. Fig. 3- is a sectional elevation showing another step in the operation wherein the blank is bent to form an inner and outer plate and a plurality of fingers extending outwardly from said inner plate. Fig. 4- is a sectional elevation showing the finished socket member with the ends of the fingers extending under the rolled over periphery of said plates and the edge of the stock around the central aperture in the outer plate being rolled inward to form "a bead. Fig. 5 1s a plan view of the socket member.

Our improved socket member is preferably formed froina single piece of sheet metal, the same being provided with a plu-. ralitv of fingers 10, thenumber preferably employed being four. The outer ends of these fingers are preferably formed with a V-shaped notch forming points 11-- 11 which are adapted to be more readily bent to passunder and be engagedby the rolled over .peripheral edge presently described. The body portion of this member is bent into the form illustrated in Fig. 3 comprising an outer plate 12 preferably bent into a concavo-convex shape and than doubled practically upon itself forming an inner plate13 having its outer edge integral with that of the outer plate 12. The fingers 10 are formed to extend outward from this inner plate and are bent near their middle portion, as at 14, said'bent over portion 15 extending on. an outward angle with its pointed ends resting on the inner plate and near its periphery. That portion of the fingers between the bend and the inner plate isofiset inwardly as at 18 forming a contracted neck portion and a comparatively enlarged inner socket portion for receiving and retaining the head of. the stud 19, see

Fig. 1. In order to secure the ends of thesefingers in position the peripheral folded edge 16 of these plates 12' and 13 is rolled inward forming an undercut or groove '17 intowhich these finger ends extend. The outwardly extendingportion 15 of the fingers serve to stiifen and support their gripping neck portion whereb said fingers Wlll retain the head of the stud in its socket portion against considerable strain to withdraw it. I

It is found in practice that where fasteners of this character-are applied to such small light articles as ladies gloves and the like, that they should release with a comparatively slight pull, but Where fasteners of this character are applied to suspenders, automobile tops, clothing, and the like, where it is necessary to resist considerable strain, it is found necessary to supportand stiffen the gripping fingers so that they will resist considerable strain and will not permit the head to be too readily drawn from its socket, therefore to accomplish this our present construction provides supports for said fingers set on an angle thereto to extend from the peripher of the plate to the outer orengaging en s of said fingers to support and materially stifii'en the'same.

Another feature of this invention is that the outer plate 12 is provided with a central -opening 20, the stock at the edge of which is. rolled inward as at 21, see Figs; 1 and 4, providing a head which serves a double purpose, first, to stiffen the-stock at this point around-the opening, and second, toprovide a means for retaining the neck of thecap, presently described. This socket member is designed to be permanently secured to the article or goods a by means of a cap member 22, said cap member being provided with an enlarged finished head 23 and a neck portion '24 the end 'of the stock at the neck portion being adapted to. be passed through a hole in the goods and through the opening-20 in the outer plate 12 of the periphery of said base being folded upon the ends of said fingers to clamp them in position.

2. A socket member consisting of a single sheet ofmaterial bent upon itself to form a base comprising inner and outer plates, the

inner edge of said inner plate having a plu-- rality of integral spring fingers bent downwardly with their ends resting upon the outer ed e of said inner plate, saidtongues being 0 set between the bend therein and said inner plate to form an enlarged socket, and the periphery of said base being folded uponthe ends of said fingers to clamp them in position.

3. In a separable fastener, a socket memberconsisting of a single sheet of material bent upon itself to form a base comprising inner and outer plates, said outer plate having a central opening, the inner edge of said lnner plate having-a plurality of spring tongues bent downwardly and outwardlyv with their ends resting upon the outer edge of said inner plate, the periphery of said base being bent upon the ends of said fingers to clamp them in position, and means passing through the opening in said outer plate and engaging the periphery thereof for securing said socket upon a fabric.

In testimony whereof We affix our slgnatures in presence of two witnesses.
