摘要： An electrically controlled sewing machine includes a needle bar, a needle plate, a feed dog, a feed dog vertical drive mechanism, a feed dog front/rear drive mechanism, an embroidery drive mechanism, and a feed dog retraction mechanism. The feed dog retraction mechanism includes a switching operation lever. The feed dog vertical drive mechanism includes a normal sewing drive cam and a retraction drive cam, which are switched between using the switching operation lever. The retraction drive cam drives the feed dog to rise upward by about 1 mm when the upper thread is being tightened, that is, at about 40.degree. to 90.degree. phase at the end of the thread tightening operation by the upper thread take-up lever. Because the feed dog moves upward only about 1 mm, it remains retracted below the level of the needle plate and will not interfere with movement of a workpiece cloth mounted in an embroidery frame. However, because the feed dog moves upward, the lower thread and the upper thread loop, which is being tightened at this point, can easily be pulled through the space between the connection portion at the front end of the feed dog and the vertical axis oscillating shuttle position beneath the connection portion of the feed dog. The lower thread and the upper thread loop can pass through the space without any resistance. Therefore, the thread tension will not degrade, so that attractive stitches can be formed.

摘要： An improved structure high speed zigzag stitch industrial-use sewing machine in which a vertically extending columnar elevated material feed needle plate platform (Post Bed) structure is disposed below the needle holder of the sewing machine. The drive mechanism of the revolving shuttle and the material feed dog plate are situated in the interior section of the elevated material feed needle plate platform, with changes in the type of stitches sewn by the sewing machine governed by a pattern cam. As such, the elevated material feed needle plate platform (Post Bed) structure provides for wider applications than conventional level platform-type material feed needle plates which are incapable of easily sewing across concave, convex, and other irregular contours of objects being processed. The present invention is not only capable of various types of zigzag stitching, but also provides for the sturdier sewing and a more attractive appearance of finished objects, while increasing the value, product quality and productivity of sewing machines in this category of industrial equipment.

摘要： The lifting device (19) of the presser foot (21) of a sewing machine is operable through the use of an operating axle (18) and a toggle lever (20). The operating axle (18) is connected to a slide (15) capable of engaging and disengaging a coupling mechanism (10). The coupling mechanism (10) is arranged between the lifting device (6) of the feed dog (3) and the oscillating drive means (7) of the lifting device. During the lifting of the presser foot (21) by means of the toggle lever (20), the coupling pin (12) of the coupling mechanism (10) is simultaneously placed out of engagement with the driven oscillating lever (8) by means of the slide (15). Thus the drive of the lifting device (6) is interrupted, and a spring (13) pulls the feed dog (3) into its lowered position. Thus the manipulation of the sewing material is made possible without the feed dog presenting an obstacle.
