Abstract

225,371. Fairweather, W., (Singer Manufacturing Co.). Nov. 21, 1923. Sewing-machines; thread-cutters and threadend holders.-A needle-loop detaining blade 34 pivoted below the throat plate is provided with a projection 35 having a cutting-edge 36 for both needle and bobbin-threads set inwards from the outer edge 40 of the blade and coacting with a ledger-blade 39 mounted inwardly from the cutting edge, the purpose being to avoid accidental severing of the supply limb s of the needle-loop. The thread-nippers for the bobbin-thread b comprises a pair of fingers 43, 44 spaced slightly below the blade 34 and having divergent tips between which the thread is guided. A thread-gripper 47 of usual hooked form is provided to engage the needle-thread w and nip it against the underside of the throat-plate 30, at the same time cutting off any excess of needle-thread against a sharpened ledge-blade 49. An additional blade 51 having a thread-guiding point 52 is secured above the blade 49, the combination serving instead of a single sharpened blade with a V-notch. The mechanism is described in connection with a machine of the kind set forth in Specification 206,710 for producing groups of stitches and in which the needle-loop is given a half twist.
