Abstract
A lubricating system for sewing machines is produced with the sewing machine running by cutting a predetermined amount of cotton fibers into small lengths and blowing the fiber lengths into the sewing machine housing. As the fibers fill the housing a felt cushion conformable to the paths of motion of the parts of the mechanism is produced. The felt cushion is supplied with oil through a wick.
