摘要： A control mechanism for the synchronized operation of the hook, the fabric feeding latch and the needle bar of a sewing machine comprising a main drive shaft driving two juxtaposed eccentrics, one connected through a drive mechanism to the hook for imparting oscillatory movement thereto, the second being drivingly connected through a second mechanism to the fabric feeding latch for imparting oscillatory movement thereto which is synchronized with the oscillatory movement of the hook. The mechanism connecting the second eccentric to the fabric feeding latch includes an adjustable arrangement for adjusting both the stroke of the feeding latch and the direction of its oscillation. The main drive shaft also drives the needle bar through an adjustable mechanism by which the amplitude of zig-zag stitches can be adjusted as well as the centered position of the needle bar. The needle bar is driven in up and down movement from the main shaft through a mechanism with an eccentric which slidably and guidably supports the thread tensioning lever. The needle bar is so constructed that the needle can be inserted in a singular position thereinto, and the needle plate is mounted on the frame of the machine, through the intermediary of studs which cooperate with sloping faces of a slot formed in the frame and resilient tongues which engage beneath the faces of the slot.

摘要： PROBLEM TO BE SOLVED: To improve a looper drive.SOLUTION: A sewing machine (1) includes: a frame (5a); a needle bar (9) driven so as to vertically move; a sewing needle (10); and a looper (11). The looper is driven by a looper drive (14) so as to swing back and forth around a looper swing axis (12) of a looper swing shaft (13) and forms stitches in cooperation with the sewing needle (10). The looper drive (14) includes a drive unit (15) for causing transmission swing motion around a transmission swing axis (17). In addition, the looper drive (14) includes a traction drive (26) including traction means (25) to convert transmission swing motion (16) around the transmission swing axis (17) into drive swing motion of the looper swing shaft (13). As a result, the looper drive in which a mechanical load on components is reduced is obtained.

摘要： PROBLEM TO BE SOLVED: To solve a problem of a sewing machine incapable of sufficiently performing no oil feed to various mechanisms near a sewing fabric. SOLUTION: This sewing machine is provided with a needlebar mechanism, a thread catch mechanism, etc., to be disposed adjacent to the sewing fabric S. Support components 15, 22 and 31 supporting movable components 11, 21 and 32 out of the mechanisms are formed of a sintered body formed by dispersedly disposing solid lubricating materials Y in a base metal X including copper and tin so as to improve the abrasion resistance and dispensing with oil feed for a long period. This constitution can dispense with forced feed of lubricating fluid so as to prevent the sewing fabric from being dirtied with oil. COPYRIGHT: (C)2003,JPO
