Abstract
A sewing machine presser foot lubrication system which includes apparatus to directly supply a lubricating fluid to the underside of a presser foot. The apparatus includes a small lubricant flow tube attached to a forwardmost underside portion of the presser foot. By such direct attachment of the lubricant flow line to the presser foot, a more effective lubricating function between the presser foot and a work piece is achieved. The apparatus further consists of a lubricant reservoir and the appropriate valving to control the lubricant flow rate therefrom. The flow tube is in two sections wherein a flexible second portion can be quickly disconnected from a rigid first portion which is integral with the presser foot.
