Abstract

107,812. Fairweather, W., (Singer Manufacturing Co.). July 12, 1916. Overhead sewing-machines.-The looper-bar 31 is pivotally connected with and derives vibratory and endlong reciprocatory movements from a rocking and reciprocating element pivotally mounted on a swinging arm 12 and of cruciform shape having two arms 15, 16 with rollers 17 and 18 engaging differently shaped cams 6, 9 on two intermeshing gear wheels 5, 8, one of which is fixed on the main shaft 3, and the other is secured to a countershaft 4. The con. nexion of the looper bar with the cruciform element comprises a split socket 29 in which the bar is clamped and which is pivoted between jaws on the end of a pin 26 which is pivotally mounted in a bearing carried by the offset end of a plate 23 secured bv set-screws and slots 21, 22 to the arms 19, 20 of the cruciform element. The sideway vibratory movements of the looper bar are obtained by mounting it in a tilting sleeve 37 which is pivoted at 38 between lugs on a block 39 pivoted in one arm of a bellcrank lever which is pivoted on the stud 44 and is rocked by the connexion of its other arm with the end of a swinging lever 55 supported by the shaft 4 and is actuated by its roller 54 traversing a cam-groove on the opposite side of the gear wheel 5 to that in which the cam-groove 6 is formed.
