Abstract
A work feeding device for sewing machines is disclosed in which an auxiliary feed dog section is constrained closely adjacent to the needle hole on a straight stitch throat plate. The auxiliary feed dog section is formed with surfaces adapted snuggly to embrace at least one limb of a conventional feed dog of the type with wide spread side limbs suitable for accommodating zig-zag stitching. All of the motions are imparted to the auxiliary feed dog section by the conventional feed dog which it embraces.
