Abstract
Presser-foot apparatus is disclosed which is capable of automatically adjusting to various levels of sewing. The presser-foot is slidably held within a housing affixed to a needle bar. The presser-foot is biased against the housing so as to move in conjunction therewith until contact is made with the workpiece. The presser-foot exerts a steady, unvarying pressure on the workpiece while the needle associated therewith continues downwardly. The presser-foot is ultimately lifted from the workpiece during the upward retraction of the needle from the workpiece.
