BUTTON-HOLE PIECE.

SPECIFICATION forming part of Letters Patent No. 373,153, dated November 15, 1887,

Application filed September 13, 1887. Serial No. 249,556. (No model.)

To all whom it may concern:

.Be it known that l, JOHN Renon, of Boston, county of Suffolk, and State. of Massachusetts, have invented an Improvement in ButtoneHole Pieces, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve the manufacture of button-hole pieces, especially as to the manner of securing the staycord and thrulnbs between the small or inner ends of adjacent button-holes, this present invention being an improvement on that vdescribed in United States Letters Patent No. 368,619, granted to me on the 23d day of August, 1887, the button-hole piece Vherein shown having the stay-"cord and thruinbs bound down or blind-stitched to its under side by two threads rather than by one, as in the said patent, the threads used not, however, appearing at the face side of the material.

My invention consists, essentially, in a but ton hole piece having its stay cord and thrumbs bound down or blind-stitched to the material at its under side by astitch composed of two threads, neither of which show at the face side of the material.

Figure 1 shows a portion of a button-piece folded upon itself in the direction of the length of the. stay-cord connecting the ends of adjacent button-holes. Fig. 2 shows the under side of the material laid out dat after the stay-cord and thrumbs have been stitched down; and Fig. 3 is a section in the line x, Fig. 1, to show the path traversed by the needle, the latter being shown in its -two different positions by ful-l and dotted lines, only a portion of the stitches and stay-cord being shown.

The button-hole piece a, of any usual ma.-

terial and shape-preferably, however, of leather-is provided with a series of buttonholes, which are overstitched, as at b, at their edges in any usual or suitable overstitching-machine, but two or three such overstitches being shown in Fig. 2a staycord, as e, being used in usual manner about the button-holes under the overstitching and from one to the next button-hole.

After the removal of the overstitched button-hole piece from the machine the ends of the needle-thread, as d, are drawn through to the under side of the material, the said ends being called thrumba the under thread used in the overstitching being usually left lying along by the side yof the stay-cord, as at o, between adjacent button-holes. In this condition the button-hole piece is folded in the direction of its length in the line of the stay-cord, as in Fig. 1, so as to leave the stay-cord on the convexed edge of the folded material, as shown in Figs. 1 and 3, and then the folded or bent material is laid upon the bed of another sewing-machine, when it is subjected to the action of an eye-pointed needle, asf, it having a thread, as t, which, when the said needle occupies the full-line position, Fig. 3, will descend and penetrate the material back from its folded or bent edge, the needle at such time, however, entering and emerging from the same side of the material; but at its next descent, when in the dotted-line position, the needle passes the material at its folded or bent edge, a loop of the thread t of the said needle at each descent being entered by a second or under thread, as h, carried, preferably, by a shuttle, as in the machine described in my application, Serial N o. 248,827, iiled September 5, 1887.

Viewing Fig. 3, it will be seen that the needle at one descent enters the material at one side of the stay-cord and thrumbs laid parallel to it, and at the next descent at the other side of the said stay-cord.

By putting equal tension on the threads t and'h the needlethread t, as it rises after having descended over the edge and outside the. stay-cord and having had its loop entered by the needle-thread, draws the loop of under thread, h, up with it for about one-half the thickness of the folded material, as shown .in Fig. 1.

To facilitate and insure the correct operation of the needle with relation tothe folded or beni; edge of the material, the seid edge In testimony whereof Ihave signed my name Io will in practice he guided by e guide having to this specification inthe presence of two suba eouenved face, :is iu my said application. serihing witnesses.

I claim- The he1'eiu-deseiibed button-hole piece, it JOHN REEGE. having its stay-cord and thiumbs hound to the under side ofthe material by two threads, Vitnesses: as t h, neither of which appears :it the face of G. XV. GREGORY, the mhteriai, substantially as described. B. DEWAR.
