摘要： A looper drive mechanism for a sewing machine includes: two loopers; looper drive shafts for driving the loopers; a main shaft extending across one plane transverse to the looper drive shafts; and torque transmission units for transmitting rotation of the main shaft to the looper drive shafts. The transmission units include: two slant grooved cams fixed to the main shaft and having grooves each extending through a full circumference and slanting relative to the main shaft; U-shaped followers each having two rollers, each of the rollers being supported by the looper drive shaft and rotating about its own axis within the groove of the slant grooved cams; and connection pins for pivotally mounting the U-shaped followers on the looper drive shafts so that the U-shaped followers are not rotatable in a direction in parallel with a line connecting the two rollers with each other but rotatable in a direction perpendicular to the line connecting the two rollers with each other.

摘要： The output centerpoint of a Cardan gear mechanism is connected via a ball and a pin slideable therethrough to a lever which in turn carries a looper. Because the major axis of the lever and the axis swept out by the output centerpoint are skewed the lever is reciprocated back and forth along its own major axis while being rotated therearound. This results in the looper being swept back and forth along part of a generally helical-like path.
摘要翻译：万丹齿轮机构的输出中心点通过球和可从其滑动的销连接到杠杆上，杠杆又带有弯针。因为杠杆的长轴和由输出中心点扫过的轴线偏斜，所以杠杆沿其自身的长轴在其周围旋转时往复运动。这导致弯针沿着大致螺旋状路径的一部分来回扫过。

摘要： A driving assembly includes a shaft pivotally supported in a sewing machine. A rod is movable up and down and includes a looper secured on top. A follower is secured to the shaft and includes a post. A block is slidably engaged on the post and includes a pivot axle pivotally coupled to the rod for moving the rod up and down. The block is adjusted along the rod for adjusting the distance between the pivot axle and the shaft and for adjusting a moving stroke of the looper. The rod and the looper are stopped when the pivot axle is moved to coincide with the shaft.
