摘要： A thread take-up lever in a sewing machine in which the driving curve disc (17) of the take-up lever is mounted on the crankshaft (10) driving the needle bar up and down. Because the driving curve disc is merely supported on one side, the spacing on the other side can be fully utilized. This provides for a correct position of the thread take-up movement from a pattern point of view. To avoid play between the curve (17) and the curve follower (25), the curve has chamfered side walls and the curve follower has a tapered, blunt tip.

摘要： A sewing machine that has at least one needle which moves with alternating motion, taking the upper thread through the piece to the sewn, a shuttle to hook an upper thread to form a loop below the piece to be sewn, a bobbin housing in a bobbin-case located internally in the shuttle, the bobbin containing a lower thread which overlaps the upper thread through the loop, two mutually independent levers which act on the upper thread and are mobile with periodic motion between a position where the upper thread is allowed to be fed to the shuttle and a position of complete recovery of the upper thread in which the loop is closed to form a stitch, the upper thread being synchronized with movement of the levers by periodic tension.

摘要： A regulating mechanism for needle thread between a standard thread tensioning device in the head of the upper arm of a sewing machine and the eye of the reciprocable needle employs a lever-shaped takeup member which is oscillated in the head in synchronism with the movements of the needle, and a wire spring which is mounted directly on the takeup member. The spring has a U-shaped thread engaging portion which surrounds and cooperates with a hook-shaped arm of the takeup member to define a passage for needle thread. The spring tensions the thread during certain stages of each stitch forming step.

摘要： A sewing machine with thread take-up mechanism is so constructed as to vertically move a take-up member, supported on a needle bar in such a manner as to be vertically movable at a timing which is different from that of the movement of the needle bar on which the take-up member is moved. The take-up member has a hole through which a thread being lead to the sewing needle is inserted.

摘要： A slit (7) is formed which lies in a vertical plane and extends from an upper surface of a sewing machine frame (1) to a front surface. A tension device (5), a thread take-up spring (30), and upper and lower thread guides (23, 24) are disposed along the direction in which the slit (7) extends. A thread take-up lever (12) is installed so that it is reciprocated horizontally across the space between the pair of thread guides (23, 25). The placement of the thread in the tension device (5), thread take-up spring (30), and two thread guides (23, 24) can be attained by simply pulling the upper thread vertically downward through the slit (7). When the thread take-up lever is reciprocated, during its forward stroke it arrests the portion of the thread positioned between the two thread guides (23, 24) and draws it in V form. During its return stroke, the thread take-up lever (12) releases the thread to allow the latter to loosen in loop form.
