STITC HED BUTTONHOLE.

Specification of Letters Patent.

Patented Oct. I!) l App1ication filed June 20, 1911. Serial No. 634,284.

To all whom it may concern:

Be it known that I, EDWARD B. lnnnn, a citizen of the United States, residing at Bridgeport, in the county of Fairtield and has long been common to lay a cord within the edge-covering over-seam stitches upon either the upper or lower face of the fabric, the cord within the overseam having been cut from the supply subsequently to stitching, so as to leave loose ends thereof at one of the-extremities of the buttonhole, as in the production of buttonholes for cloth work, or the cords applied to the lower face of the work have been led into and out of the initial and final overseam stitches to connect with those of the adjacent buttonholes of a series upon the lower or unexposed face of certain articles in leather work, such as shoes.

One of the chief objects of applying a corded overseam to the edges of a buttonhole slit with the cord upon the upper side or face ofthe material is to improve the appearance of the work by giving the overseam a body so -as to simulate a bead or ridge around the edge of. the buttonhole slit while the margin of the slit is effectively covered, even with the over-seam stitches comparatively widely spaced.

While certain of the described advantages have been secured heretofore by the employment of'a corded overseam, the buttonhole' has been seriously marred in appearance by the protruding out ends of the cord r face of the fabric, and it is the object of the present invention to produce a buttonhole with the edges of the slit covered by a corded overscam with the extremities of the cord wholly confined with in the oversearn and entirely concealed by the same.

According to the prescnt\ invention the buttonhole is formed with an overseam extending along both edges and embracing a cord whose cXl-rcmilics are confined within and concealed by tho ovcrscam. i

The invention further includes a buttonbolc formed with an o\-crsc.-un overlying both face a cord with i-onccahal extremities being embraced by said over-scam upon one face of the fabric and a cord with its cud portions extending through and bovond the ends of the overs-cam being embraced within the latter upon the opposite face ol the fabric.

The invention will be undcrstmul by rot'crence .to the accompanying i'lrawiugs, in which- Figure l is anuppcr face view of a portion of fabric provided with a buttonhole embodying'the present invention. and Fig. :2 an enlarged perspective view of the saine. Fig. 3 is an under side view of a portion of fabric containing two buttonlmles cmlnulying the present invention and showing the lower cords embraced by the overscani and led laterally through and beyond the e. tremitics thereof in a manner well known.

The buttonholc of the present improvement is or may be produced by the en'iployment of the buttonholcstitching and cordhandling devices forming the subject of my pending application Serial No. 632,3Il2filed June 10, 1911. As represented in the drawings, the fabric 1 is provided with the buttonhole slit 2 with enlarged or eyelet portion 3 whose margins are covered by the over-seam, formed in the present instance of interlooped upper thread a and lower thread 5.

As represented in the drawings. the overseam is produced by a stitch-forming mechanism comprising a jogging needle in conjunction with threaded and non-threaded lcopers. The needle makes an initial dcsccnt through the fabric carrying with it a depth-stitch loop a of its thread which is detained while the needle rises and descends through the slit to pass an edge-stitch loop a? of its thread through the previous depthstitch loop a. the cdgestitch nccdlc-thrcznl loop being entered by the threaded looper which passes through the same a loop bof lower thread which is distended for passage of the needle in ilancxt depth-stitch thrust in which it carries the succeeding (lcplhstitch loop through the fabric. The buttonhole is herein represented as of the cyclolcnd type, with long barring stilclu-s arranged across lhc narrow end with tho cxtrcinitics of the stitches in alim-nn-nlwilh the depth m'cdlc-punclurcs ol the sidestitches.

The machinc rcprcscnlcd in my pending lllll lllfx llO application Serial No. 632,332, before mentioned, is constructed to produce by a continuous operation series of edge-covering.

overseam stitches and connected barring stitches, so that the latter have their com ponent threads continuous with those of the edge-covering stitches.

As represented in Figs. 1 and 2, the upper or needle-thread a overlies the margin of the fabric around the buttonhole slit and interposed between the same and the upper face of the fabric is the cord 0 which follows the contour of the buttonhole slitand is shown as having its extremities c terminating be neath the limb of the upper-thread d extending between respectively the first and last depth-stitch needle'punctures and the adjacent edge-stitch loops a While this is the preferable arrangement, it is obviously immaterial whether the extremities of the.

cord lie beneath any of the first or last few -of the edge-covering stitches or beneath the:

barring stitches, in case thefbutto'nhole is of the barred end type. The improvement is obviously applicable to straight buttonholes in which the edge-covering. stitches extend in parallel lines throughout the length of the buttonhole whose ends are reinforced by barring or other stitches.

of the material is provided with asecond cord (1 which-extends laterally from the left ,across the closed extremity of the first buttonhole slit and along its right-hand edge,

5.35 around the eye and thence along the lefthand edge Where it crosses the first section and is led across the closed end of the adjacent buttonhole and along its right-hand edge and around the remainder of the slit as i549 -.;gereviously described. In the completed but-"' tonhole, the initial portion of the cord enters and emerges from the adjacent ends of the covering o'verseam by which it is embraced,

the portions at the extremity of the buttonhole being overlaid by the barring stitches s ;trom which the under thread 6 is led to the initial covering stitch of the adjacent I f buttonhole.

gThe edge-covering stitches are shownin y' tfihpies of this patent may lie obtained for As represented in Fig. 3, the under facequired effect, ;and this condition involves economy in both the time and thread re-.

quired in, the production of the buttonhole, while it isfound that a cheap cotton cord may be readily used to advantage where a silk covering thread is required without pro-.

ducing a icontrast which isdetrimental to the appearancewof the buttonhole. The covering stitches are herein shown and described" as of the two-thread chain-stitch type, but the specific character of the over seam and thejmethod of making the same are obviously immaterial to the present im provemen'ti Having thus set forth the nature of the invention, what I claim hereinfis 1. A' fabric havinga stitched buttonhole comprisin an overseam extending along both edge and' itrouiid an endof the same,

and a cord-embi'iyiivithin saidioverseam and overlying thelouter or exposed face of the fabric warming-its extremities at the opposite end'of the buttonholecovered and concealed by said overseam. 1

2. it fabric having ,a" stitched buttonhole comprising a continuous oyerseamextending along both edges and acrhss an end'o-f the same', and a cord embraoedwithin said over seam and overlying the outer or exposed face of the fabric with its extremities at the opposite end of the but-tonhole covered and concealed by overseam stitches whose component threads are continuous with those of the adjacent stitches along the' edges of the buttonhole.

In-testimony whereof, I have signed my name to this specification, in the presence of:

two subscribing witnesses.
