    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 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 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 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.

    摘要: An upper thread carried by a vertically reciprocating needle is drawn from a bobbin through a tensioning device, a supply device and a take-up lever. A predetermined amount of the upper thread is first supplied by actuating the supply device, while applying no tension thereto. An additional amount of the upper thread is then supplied by operation of the take-up lever with a predetermined tension being given thereto. The additional amount is detected by a sensor. The supply device includes a one-way clutch for allowing the upper thread to travel in a predetermined direction which, however, may not be conveyed from the needle side when the supply device is made operative. A CPU controls the amount of thread first supplied by the supply device which will always be smaller than an amount actually required for producing a stitch, resulting in an additional amount to be supplied supplemental in cooperation with the tensioning device.

    摘要: A double-function sewing machine, which is provided with a lock stitch forming mechanism and an overlock stitch forming mechanism, has a common driving source and a common flywheel for the two mechanisms. The sewing machine is provided with a switching device which includes a switch key connected to the flywheel of the machine. The switch key is selectively switchable to engage the shaft of the lock stitch-forming mechanism or a drive of the overlock stitch-forming mechanism. The switching device further includes a switching pawl which is engageable with and disengageable from the drive of the overlock stitch forming mechanism to hold the latter when the lock stitch forming mechanism is operated.
