    • 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.
    • 缝纫机的压脚(21)的提升装置(19)可通过使用操作轴(18)和肘节杆(20)来操作。 操作轴(18)连接到能够接合和分离联接机构(10)的滑块(15)。 联接机构(10)布置在进料斗(3)的提升装置(6)和提升装置的振动驱动装置(7)之间。 在通过肘杆(20)提升压脚(21)期间,联接机构(10)的联接销(12)同时被放置在与被驱动的摆动杆(8)的啮合之外,借助于 幻灯片(15)。 因此,提升装置(6)的驱动被中断,并且弹簧(13)将进给爪(3)拉到其降低的位置。 因此,无需进给狗出现障碍就可以进行缝制材料的操作。
