Abstract

194,537. Fairweather, W., (Singer Manufacturing Co.). March 8, 1922. Loop - stitching. - In overseaming stitch-forming mechanism, means are provided for bending the looper-thread between the looper and the last stitch towards the plane of the work, thereby facilitating the setting of the purl close to the edge of the seam. In the button-hole sewing-machine described in Specification 179,278, the loopdetainer 9, Fig. 1, is formed with a horn 20 having a point 21 projecting forwardly beyond and over the loop-seizing horn 18 of the detainer 9. When the looper 18 enters the depth-stitch needle. loop 17 as shown, the horn 20 passes below looper-thread 19 and lifts it so that the su'bsequent pull on this thread sets the purl on the button-hole edge. The horn 20 also prevents the detaining-horn, 18 catching the looper-thread.
