MACHINE FOR FINISHING- BUTTON-HOLES.
v SPECIFICATION forming part of Letters Patent No. 376,245, dated January 10, 1888.
Application tiled Febrn ry 3, 1857. Serial No. 226.394. (NomodclJ To all whom it may concern..-
Be it known that I, GEORGE S. HILL, of Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in Sewing-Machines for StitchiugDown the Stay- Cord ofButtonHoles, of which the following description, in connection with the acco1npanying drawings, is a specification, like letters on the drawings representing like parts.
'Overseaming or button-holestitching ma chines now commonly employed to stitch button-holes in button-hole pieces of bnttonboots employ an upper thread, a lower or under thread, and a third or bar thread, over which the stitch is made along the edge of the buttonhole. In machine-made button-holes of this kind the small end of each button-hole, as its last straight side is stitched, is left'with two projecting free ends of thread, both belonging to the needle-thread and being located at the small end of the said hole, one being at the point where the stitching is commenced and the other where the stitching is left off, both the said ends appearing at the under side of the material. The under thread and the barthread, by the movement of the material by hand from one to the next hole, are left extended at the under side of the material from the last side of one to the first side of the next 30 button-hole, and frequently the under thread is longer than the bar-thread.
To obviate either the necessity of cutting off or whipping down the projecting ends of the threads referred to, and to cover or inclose the said ends together with the under thread and bar-thread extended from one to the next button-hole, I have provided a throat or cover plate having converging guiding or gathering surfaces, which act to gather into line with the needle of the throat-plate all the project ing ends of thread left at the end of the button-hole and between the small ends of adja cent holes.
The needle-throat is made double to permit the passage through it of two needles carried by one needle-bar, the two needles descending at opposite sides of the bar thread or cord, the two loops of thread taken from the two needles at opposite sides of the bar-thread and gathered ends being ventered bya suitable shuttle or looper. (Not shown.)
The invention consists in the mechanism hereinafter particularly set forth and claimed.
Figure 1 in top view shows a throat-plate embodying my invention; Fig. 2, a section of Fig. l in the dotted line 00 00. Fig. 3 is an end view of Fig. 1, looking at it in the direction of the arrow 10, the said figure also showing two eye-pointed needles and the needle-bar carrying them. Fig. 4 on a large scale repre- 6o sents the under side of a button-hole piece, showing two button-holes with the threads used in their production; Fig. 5 shows a like view with the addition of the stitching to inclose the free ends and the bar and under thread shown in Fig. 4, three threads being employed to cover the loose ends and the bar and underthreads, two of the said threads being carried by two 'eyepointed needles, while the third thread comes from a shuttle or bob- 7o bin; and Fig. 6 is a view of the opposite side of Fig. 5.
The edge of the button-hole a (see Fig. 4) in the button-piece A is supposed to be overstitched by a needle-thread, a, and an under 7 thread, .9, a bar-thread, I), being laid under the over-edge stitching entirely about each button-hole and from one to the next button-hole, as shown in-Fig. 4, all as usual.
In Fig. 4 the button-hole at the under side of the material presents two free ends of needle-thread, as at a a, one end projecting from each straight side of the slit at the small end of the hole, as in said Fig. 4, where the ends are shown separated to enable them to be clearly. represented, one end being drawn down or'through the button-hole slit from above preparatory to whipping the same together by machine-stitching. Sometimes these ends of the needlethread n are cut off, when the end 9c of the button-hole is finished by hand; but preferably, as has been done, these two ends and the bar-thread b, and the bight of under thread, 3, extended from'one to the next hole, are whipped overby a thread in a hand-operated needle. To obviate this hand-finishing, and at the same time avoid cutting oftprojecting ends of thread, and to make the said ends serviceable in the production of a stay for the button-hole piece, I have provided a novel 10 throat or cover plate to gather the projecting ends together, as in Fig. 5. This throat or cover plate (I has an opening, 0, for the usual feed-dog, and a needle passage or throat, as e, the latter being made wide enough for the passage of two needles, asfg, held side by side in one needle-bar, h, actuated in usual manner, each needle having its own thread, the loops of needle-thread passed below the material, and the plate (I! being entered by a shuttle, as in the Singer system of sewing, or by a hook, as in the \Vheeler & \Vilson system of sewing, and having left in them a third thread carried by a shuttle, or by abobbin within the said hook, the loops of needle-thread being thus entered by an under thread, as 13, to complete a three-threaded stitch below the material, the thread 13, carried by the shuttle or bobbin, crossing the gathered ends a and the bar-thread I) and under thread, 8.
To cause thefree ends of the thread a to form a part of the stay, the under side of the button-hole piece, with its projecting ends it n, is laid upon the throat or cover plate d, and the material acted upon by the usual feed is moved in the direction of the arrow 10, and during such movement the converging edges 12 12 of the guide act to gather the said ends together, so as to form a bunch of ends in line with the line of stitching, the said ends being gathered together alongside of and to cooperate with the under thread, s, and bar-thread b,extended from one to the next button-hole, the assembled threads being led between the two side walls of the narrow slot 25 (see Fig. 1) into and across the needle-hole e, the two needles fg in their descent passing the saidassembled threads at opposite sides. (See Fig. 5.)
The needle f carries a thread, 15, and the needle 9 a thread, 16, each particularly shown in Fig. 3, the said threads being taken from usual spools. (Not shown.)
A shoe provided with a stay such as herein represented has been made the subject-matter of Letters Patent No. 360,590, granted to me April 5, 1887.
I claim- The within-described mechanism for use 011 ordinary sewing-machines for gathering in and confining the needle-thread ends, the under thread, and the bar-thread of machine-made button-holes, the same comprising two needles U operated simultanconsl y in the same direction in conjunction with the usual complemental stitch-forming mechanism and the throat or cover plate d, having a longitudinal slot lead ing to the needle-hole and provided with the sides 12, converging toward such needle hole and meeting in the straight slot 25 im mediately in front ofthe needle-hole, whereby the buttonhole piece is fed smoothly upon the Hat surface of the throat or cover plate without interruption from the edges of the longitudinal slot, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
GEORGE S. HILL.
