    摘要: A sewing machine comprises a thread deflecting device arranged between a thread take-up lever and a needle and which in response to a swinging movement of a needle bar effected in response to selection of a zigzag stitch, deflects the upper thread laterally of a fabric feeding direction. A thread blocking device is provided on one side of the thread deflecting device. The sewing machine further comprises an actuator operated in response to actuation of a zigzag stitch pattern selecting key to move the thread blocking device to an operative position thereof. The thread blocking device in the operative position blocks the upper thread as it is deflected in one direction by the thread deflecting device to give a predetermined degree of tension to the upper thread, so that the stitch is tightened on one side of the zigzag stitch in addition to the tightening of the stitch by a thread take-up lever.

    摘要: A sewing machine includes an automatic thread tension adjusting device comprising an upper thread tension member arranged in an a thread running path between an upper thread source and a main thread take-up lever. An auxiliary thread take-up lever is arranged in the upper thread running path between the main thread take-up lever and a needle holding the upper thread. A thread engaging part guides the upper thread. A thread presser is arranged laterally of the upper thread running path between the main and auxiliary thread take-up levers and normally clamps the upper thread. A detector detects a predetermined rotation phase of a drive shaft of the machine and thread elongation, respectively, and generates respective electric signals. A control circuit causes the thread presser to release the upper thread in response to the electric signals generated by the detector.

    摘要: A zig-zag sewing machine equipped with pattern cams and a pattern cam selection arrangement has a compartment in which various accessories of the sewing machine are accommodated. One lid covers the compartment and another lid overlies the above-mentioned lid, the lids being provided, at their surfaces facing one another, with a table of indicia and with lines connecting the indicia with other indicia provided on a pattern cam selector dial so as to enable the user of the sewing machine to adjust the sewing machine for the particular selected stitch pattern. The lids are mounted for pivoting on a common shaft, and a sliding element is mounted on the shaft for displacement therealong and is visible when the one lid is either open or closed, the position of the slide element being selected in dependence on the selected pattern and also being indicative of the accessory to be used. An arresting arrangement arrests the lids in their closed positions for sequential release toward their open positions, and includes two latching elements each of which engages one of the lids, and a connecting element which connects the latching element associated with the one lid to the latching element associated with the other lid only when the other lid is in its open position.

    摘要: A sewing machine motor is connected to a drive wheel which can be connected via a clutch to a drive shaft that vertically reciprocates the sewing-machine needle. A cam on the shaft and a stopper on the housing are displaceable between an operative position engageable with each other for stopping rotation of the shaft in a predetermined angular position corresponding to the up position of the needle and an inoperative position unengageable with each other. A cam is provided for displacing the control element of the clutch from an engaged to a disengaged clutch position on engagement of the stopper in its operative position with the cam so that the shaft can be arrested in a predetermined angular position and is substantially simultaneously rotationally uncoupled from the wheel. Pawls engageable with a cam carried on the shaft serve to substantially simultaneously displace the clutch control element into the engaged position and the stopper into the inoperative position for starting-up of the sewing machine again after one intermittent-drive cycle.

    摘要: A method of automatically controlling thread tension in a sewing machine according to which a first thread tension device is provided between an upper thread source and a thread take-up lever, and a second thread tension device is provided between the first tension device and the thread take-up lever. The first thread tension device is operated to apply a constant pressure to the upper thread such that the thread take-up lever is able to draw out the upper thread upon moving upward. The second thread tension device is operated to fixedly hold the upper thread until the thread take-up lever moves upward to an upper dead point thereof through a lower dead point thereof, at which the take-up lever moves downward to supply the upper thread to the needle. The second thread tension device is further operated to effect release of the upper thread when the thread take-up lever reaches the upper dead point thereof and until the thread take-up lever moves downward to a thread supply starting position thereof.
