    Abstract: The needle bar (1) engaged in a pivoting cradle (2) is integral with a journal (3) connected by a connecting member (8) to a link (4) driven from the drive shaft (12) of the machine. In order to permit the head (23) of a loop holding member (25), mounted in the pedestal of the sewing machine, to engage in a loop (29) of the needle thread (27) during the ascending course of the needle (22), whatever may be its decentration, the connecting member (8) is formed by a bent extension of the crank pin of the link (4) engaged in a bore (7) of the journal (3).

    Abstract: A sewing machine includes a stud carried by a journal surrounding a tubular needle bar having a lateral opening. A link connected to the journal normally drives the needle bar when the stud is engaged within the needle bar opening. A disconnecting rod within the tubular needle bar is axially displaceable and includes a ramp engageable with a control member, also within the needle bar, to drive the stud from the needle bar opening and thereby disengage the journal from the needle bar.
