Abstract
A sewing machine utilizing an intermittent upper feeding foot to feed work material in any direction. The upper feeding foot is carried internally of and swivels within a presser tube supporting on the end thereof a presser foot. Means are provided to alternate force on the presser foot during needle penetration and withdrawal, and on the feeding foot during feeding of a work material. During the period when force is applied to the presser foot, the upper feeding foot may be positioned by driving devices to an initial position, and may be driven to a final position after the force has alternated to the feeding foot. The driving devices may be responsive to information retained in intelligence record carriers in order to achieve the initial position and the final position. One driving device is connected by suitble linkage to a Y slide movable in a 'Y' direction and connected to the end of the rod opposite the feeding foot. A second driving device is connected by suitable linkage to a X slide movable in a 'X' direction, also connected to the end of the rod opposite the feeding foot and carried by the Y slide in a fashion to limit motion thereby to the 'X' direction.
