Abstract

Vibrational movements of a spring biased lever, which is selectively positionable by a stitch length control lever and controls the operation of feed regulating mechanism in a sewing machine accordingly, are dampened by the operation of a plunger that is carried by said control lever and has a camming surface thereon to engage and lift the spring biased lever when the control lever is moved.
