ABSTRACT:
A low inertia presser device for overedge sewing machine. A horizontally disposed presser bar arm and a similarly disposed presser bar arm leaf spring are mutually pivoted at one end on substantially horizontal and vertical pivots to permit vertical movement and swing out capability. A main pressure spring acts on the presser bar arm; which in turn, through an arm extension to the presser bar arm approximately midway its pivoted end and the point of action of the main spring, applies pressure approximately midway along the presser bar arm leaf spring. A presser foot is supported on the end of the leaf spring opposite its pivoted end.
