ABSTRACT:
A low inertia presser bar carries a retaining plate which slidably extends through an enlarged slot in a hollow main presser bar that slidably receives the main presser bar. The lowered position of the main presser bar may be adjusted to position the clearance between the slot and retaining plate above the plate, or with a selected portion of this clearance below the plate for adjustable travel of the low inertia presser bar before initiating motion of the main presser bar.
