SLIDE FASTENER Filed July 23, 1930 Patented Oct. 4, 1932 UNITED STATES PATE reseau Nrv orifice 'l JOSEPH .W. DEWS, OF WATERBURY, CONNECTICUT, ASSIG-NOR T0 SCOVILL MANUFAC- TURING COMPANY, 0F WATERBURY, CONNECTICUT, A CORPORATION vOF CONNECT- ICUT Applicationl led July 23,

ble fastener, such as the socket member of a 5 snap-fastener, in which the separable fastener member is so constructed as to present the least possible projection and thereby minimize the bulging of the fastened parts.

The invention in its limited aspect, consists of a slide of conventional 'or approved form adapted to be adjusted upon a strap or belt and frictionally or otherwise heldin adjusted position thereon, and provided with a resilient socket composed of 'an eyelet-like member which is open at both ends, one end of which is reduced and clinched to and upon the slide and its other end supplied with an open ring spring, adapted to engage a stud or head 20 so as to fasten together the parts upon which the slide fastener-and the stud are respectively mounted, as I will proceed now more particularly to explain and iinally claim.

In the accompanying drawingl illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a top plan view and Fig. 2 is a bottom plan view of a slidehaving a ring spring socket secured in position thereon by a reduced and solid end rolled over upon the slide. Fig. 3 is a section illustrating the application of the slide of Figs. l and 2, to a strap or belt. Fig. 4 is a sectional elevation illustrating a .suitably mounted stud or head in position to 5 lbe engaged with the socket of the slide. Fig.

5Y is a top plan view; Fig. 6 is a bottom plan view, and Fig. 7 is a cross section of a slide fastener in which the socketv element has'its upperreduced end cut, slit, kerfed or otherwise partly severed so as to Jfacilitate the attachment of the sockel element tothe slide by being rolled over the same. Fig. 8 is a section of the blank of the eyelet-like member of the socket, and Fig. 9 is a cross-section of the finished socket member ready to be ap-y plied to the slide.

The figures of the drawing are obviously enlarged.

The slide l, may be of metal and ofany shape, size or configuration to suit the use for which designed. As shown in the drawstated.

ing, the slide is designed for a strap and has two parallel straight sides with curved ends. Near each end is a transverse slot 2 and between these slots is a central opening 3. The part l is curved longitudinally to adapt it to the use to which applied. In any case, the slide may beof relatively thin material. The slots 2 are adapted to receive a strap 4L or other article to which itis applied, as indicated in Fig. 3 and is the sole strap engaging member and outside finish.

In the opening 3 is mounted the vfastening element, same being, as herein shown, an eye# letlike member 5, open at bothends, the lower portion of which is beaded to receive and sup-- port a ring spring 6. The upper end of this eyelet-like device is reduced and may be left solid as lshown in Figs.1,2l and 3, and this end is passed through the opening 3 until the slide rests upon the shoulder 7 L of the ring spring supporting bead andthen the portion of the eyelet-like device which passes through the opening in the slide is rolled over on top of the slide into intimate contact with the ytopwhereby the fastening device is firmly mounted upon the slide, and with very little and scarcely any appreciable extension above the level of the' outer surface of the slide, thereby ensuring a very fiat and symmetrical slide fastener.

As shown in Figs. 5 to Y9 inclusive, the reduced portion of the eyelet-like fastener element that extends beyond the upper surface of thek slide may be cut, slit, kerfed or otherwise partly severed, as at 8, so as to spread when this edge is rolled down over the upper surface of the slide tosecurethe ,fastening device in position.

In the unslitted eyelet-like member of Figs. l1, 2 and 3, as Well as in the slittedform shown in Figs. 5,6, 7, 8 and 9, the-shoulder 7 serves the double purpose of locating the spring in its bead and the eyelet-like member in the slide. In both assemblies as shownjres'pecl tively in Figs.;1 to 3. and Figs. 5 to 9, they shoulder 7 on the beaded end of the eyelet comes into face to face Contact with the slide member Vfor-the double purposevlast above Kee feo

fect the union of the two snap-fastener elements'.

Y v In Fig. l the stud member of the snap fastener device is shown as mounted upon -a piece of fabric or other material represented at 16.

It will be noticed that the described slide fastener is characterized by eXtreme tlatness, and that the stud in entering the socket has a tendency to protrude through the slide and this admits of the slid-e being made much thin# ner than the conventional types, especially those to which the socket is secured by means of av separate flanged eyelet.

Variations in details of construction are permissible withinthe principle of the invention and the claims following.

What I claim is 1. A slide fastener, comprising a single Vtransversely slotted slide member of relative thinness, and having a central opening through which the aftermentionedY fastener Vsocket is applied thereto, and a-socket comprising an open-,ended eyel-et-like part with one end reduced and passed through vsaid central openingand rolled down on top of the slide member and the other end beaded and a ring spring yieldingly supported in said beaded end, said beaded end having a shoulder which shoulder comes into face to face Contact with the slide element and serves to locate the relation of the socket to the slide and the spring to the beaded end.

2. A slide fastener, comprising a single transversely slotted slide member of relative thinness, and having a central opening through which the aftermentioned fastener socket is applied thereto, and a socket comprising an open-ended eyelet-like part with `one end reduced and slit at numerous points and passed through said central opening-and rolled down on top of the slide member, and

the other end beaded and a ring spring yieldingly supported in said beaded end, said beaded end having a shoulder which shoulder Vcomes into face to face contact with the slide y element and serves to locate'the relation of prising an open-ended eyelet-like part with one end reduced and passed through said central opening and rolled down on top of the slide member and the other end beaded,

a shoulder formed on the beaded end, and a ring spring yieldingly mounted in said beaded end, the said shoulder coming into face to face contact with the slide member and serving to fix the location of the socket mem-v ber' on the slide and the spring in the beadery of the aperture, the remainder of fsaid retainer -being bent first outwardly of the edgeA ofthe aperture into engagement with the other face of the slide member and then inwardly linto substantially semi-circular cross-section, and thereby forming a groove of substantially the thickness of the slide member to receive the peripheral portion of the slide member surrounding the aperture and to maintain the retainer permanently in position on theslide member against displacement therefrom, said semi-circular bent portion having an aperture in the end thereof arranged co-aXially ofthe aperture in the slide Vmember for the passage Vof a stud, and a resiliyent ring arranged in the semi-circular portion, and adapted to expand therein to permit the passage ofa stud'therepast, and to contract lto removablyrmaintain the stud in the socket afteritspassage through the aperture.

5L Av slide fastener, comprisinga "singley transversely slotted slide member, and hav'- i ing a central opening through which the kaftermentioned fastener lsocket is applied thereto, and a socket comprising an openended eyelet-like part with one end reduced. and 'passed through said central opening and rolled-'down ori-top of the slidemember and the otherend beaded and a ring spring yieldingly supported in saidbeaded end,said beaded end havin-g a shoulder which. shoulder comes into face to face contact with the slide element and serves to locate the relation of the socket to the slide and the spring tothe beaded end.'
