JAMES H. REED, OF LYNN, MASSACHUSETTS, ASSIGNOR- TO THE GLOBE BUTTON-HOLE MACHINE COMPANY, OF KITTERY, MAIN E.

' METHOD OF BARRlNG BUTTON HOLES.

SPECIFICATION forming part of Letters Patent No. 378,218, dated February 21, 1888.

(No model.)

To alt whom it may concern:

Be it known that I, JADIES H. REED, of Lynn, in the county of Essex and State of Massachusetts, a citizen of the United States, have invented a new and useful Method of Barring ButtouI-Ioles, of which the following is a full, clear, and exact description, reference beinghad tothe accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a method of barring button-holes, which embraces the sewing or stitching of the bar by stitches which extend entirely across the end of the button-hole slit, arein line therewith, and which are preferably of a length equal to about twice that of the stitch overlying the side and eye of the button-hole, and the completion or fastening of the end of thethread used informing the barringstitch by sewing one, two, or three additional stitches of substantially the length of the stitch used in sewing the button-hole itself, so that the barring-stitches are locked or fastened in place, and under such tension as may be necessary for doing good work.

Referring to the drawings, Figures 1, 2, and 3 illustrate button-holes in different stages of completion, and Fig. 4- a portion of a completed buttonhole.

The mechanism employed for carrying out the method herein described forms no part of this invention and need not be described, it being sufficient to briefly state that two threads are used and two needles and appropriate looping devices, one of which is above the work-plate and the other below.

In the drawings,A indicates the upper needle, which is moved or reciprocated continuously in the same line or path, and A is the lower needle.

In stitching the sides and eye of-a buttonhole these needles have a fixed relation to each other-t-hat is, each is reciprocated or moved upon a given line or track, which line or track is not varied in any respect in relation to the line or track of the other. At the completion of the last side of the button-hole to form the longer stitch necessary for barring the end of the button-hole, and also to form a stitch which shall be substantially twice the length of the stitch which is used upon the sides and eye of the button-hole, one needle is moved automatically from the path in which it was reciprocated, or moved away from the other needle, to a position about twice as for from it as that which it occupied during the stitching of the sides and eye, and it continues to move or reciprocate in this new position or upon this new line. This makes the length of the horizontal portion of the stitch twice that which was before sewed by the same nee- 'dles, and the needles are moved or recipro cated in their new relation to each other, and the looping devices operated to carry the upper and lower threads and spread the loops until any desired number of these long stitches have been made across the end of the buttonhole. At the completion of the last long stitch the movable needle is moved back to its original position, and one, two, or more stitches sewed through the material to fasten the ends of the threads.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States The method of barring buttouholes with two threads herein described, comprising the forming of holes in the material in which the bnttonhole is formed, one upon each side of the button-hole slit at the end opposite the eye, passing the big-ht of one thread through one of the holes, opening its loop upon the under side of the material, and passing the bight of the second thread through said loop and the other hole, and opening the bight.

threads through the holes and opened loops,
