FRED S. CARR, O1 NE'WTQN, MASSACHUSETTS, .ASSIGNGR TO (MER/TEL` FAST:[*IlllElf COMPANY, F CAlVvIBB/JIDGE, MASSACHUSETTS, A CORPORATION OF Ii/lAIlJ'llE.`

To all `whom t may con-cern: l -f y Beit known that l, FRED S. CARR, a citi- Zen of the United States, and a resident of Y Newton, in the Vcounty 4of Middlesex and 5 Commonwealth of Massachusetts, have in- 'ventedV an Vl'inprovement in Fasteners," of which' the following description, in .connection with the 'accompanying drawings,is a specification, like characters on the drawings representing likev parts; Y

This invention pertains to improvements inseparable fasteners. lt is among the ob jects of the inventionvto provide a fastener of simple and ruggedV construction and which provides satisfactory holding power. AIn the drawings, which show a preferred form of oneillustrative embodiment of my invention e yFigure 1 is an elevation of the studand socket of a fastener, the stud and socket being carried by their 'respective fabrics; f

F ig. 2 is a section on the line 2-2 of lig.A l; and v i Figs. 8' and 4 are plan views of thev preferred forms of stud and socket secured to their carrying fabric. 4

V.liteferring to Vthedraw ings, and to the preferred form o-f my invent-ion selected for l.

Villustrative'V purposes, I have shown a Stud 3o `which may be of usual `construction and includes a head 5, neck Gand base flange 7, stitched to the stud carrying fabric 8. Cooperating withthis stud l have shown a Vsocket 9, wh'lchfin the preferred form of my invention is made from a. singleV piece of sheet'metal having a stuclmeceiving aperture l() therein vand which is slotted at one side to permit resilient expansion of the sheet metal to 'enlarge'. the stud-receiving apen ture for passage of Ythe head of the stud therethrough. preferably,as illustrated, provide meansl for'liinitingthe resilient eX- pansion ofthe spring, and in-the embodivment of my invention illustrated lefect this byinaking theslot in the' socket present opposed faces l1 and l2 having a Vspace 18 be tween them, the extent of this space limiting the resilientexpansion of the sheet `metal to enlarge the stud-receiving aperture. These facesll and 12 may conveniently be formed by making the slot crooked `and I have found that the shaped slot illustrated performs this function satisfactorily, the central portion of the Z being preferably, as illustrated, lwider than the end portions thereof. Where 1 ti'on'toward the slit inthe socket.

Application led March 8, 1921i Serial No. 450,746.

my invention is used withxthe one-piece` socket' as illustrated, the spring portion being in fact the entire socket, l .may provide stitch-receiving apertures l", 16 and 17 `through the socket,Y these stitch-receiving apertures preferably .being arranged about the stud-receivingapertureon those sides thereof .which are out of the direct line of strainbetween Stud and socket when in use, that sideof the socket presenting 4the slot preferably being arranged toward the line,

Vofstrain and the stitch-receiving apertures preferably being threein number and syminetrically disposed about the other three sides of the stud-receiving aperture or openlng;

The holding.V power ofthe fastener under lateralfs'train may, if desired, be increased 'by providing a notch 18 in the sheet metal spring, preferably on that side thereof toward the slot therein which extends from the stud-receiving aperture to the periphery of 4.the socket. The resiliency of the socket may be increased by slotting theinetal between thev stud-receiving` aperture and the stitchreceiving apertures, these slots being numbered 20 on the drawing. i i

`When the stud and socket are attached to their respective fabrics'and when these fabrics are pulled apart insuch a way as to produce lateral strain between stud and socket in the direction of the arrow in Fig. of the drawings, the strain may be so great as to' enlargelsomewhat the stud-receiving aperture, but this cannot be `enlarged beyond a predetermined amount because of the limiting means limiting .this expansion, and

the expansion will not be sufficient to permit the head of the stud to tip out of the studreceiving opening `inthe socket, especially where a notch is provided permitting limited lateral displacementv of the stud in a direc- The notch 18 is, however, not sufliciently great to interfere with ready separation of the stud from 'the socket whenseparating force is applied between the engaged parts at an angle greater than that which is likely to be pro-V duced by the resolution of forces arising from lateral strain between stud and socket.

llVhile I have shown and described a preferred form of one embodiment of my invention, it Awill be understood that changes involving` omission, substitutions, alteration and reversal of parts, and even changes in the file lefof operation, may out departing from the seo-pe of my inven- 'tipnmvvhichis best defined in the following l.
