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.
