    摘要： An oscillating shuttle, including a shuttle race having a substantially annular guide groove including two end portions opposed to each other in a circumferential direction thereof, a shuttle body which includes a part-annular guided portion and a hook portion and which is oscillatory while the guided portion is guided by the guide groove, a driver which rotates the shuttle body about an axis line, wherein when the hook portion hooks a thread loop, the shuttle body is rotated by the driver in one of opposite directions such that the tail portion passes through one of the two end portions of the guide groove and enters an upper opening of the shuttle race and, when the shuttle body is rotated back in the other direction, a tail portion of the guided portion enters the one end portion of the guide groove, and at least one of the one end portion of the guide groove which has, in a direction parallel to the axis line, a width greater than a width of a remaining portion of the guide groove, and the tail portion of the guided portion which has, in a direction parallel to the axis line, a width smaller than a width of a remaining portion of the guided portion.

    摘要： An upper needle guide (10) and a lower needle guide (40) for guiding a sewing needle during a stitching operation in order to keep the sewing needle laterally aligned along a stitching path so that the thread loop thrown by the sewing needle beneath the material being sewn is in alignment with the path of movement of a thread loop pick-up device (98). The upper needle guide includes a needle hole having a thread relief passageway (22) therein for providing a relief space for the sewing thread (34) as the needle moves through the needle hole. The lower needle guide includes a thread and needle slot (44) having a pair of V-shaped notches (46) therein. The V-shaped notches are aligned with the stitching path (84). In an alternative embodiment, the lower needle guide can comprise a feed dog (52) having a diamond-shaped needle hole (58) therein.

    摘要： A zigzag sewing machine includes an oscillating hook. The transverse needle swing amplitude of the needle of the sewing machine is increased in amplitude from that of conventional free-arm domestic sewing machines with oscillating hooks, for example, from 5 mm to 9 mm. The increased amplitude is provided by a novel drive mechanism including a rack oscillating transversely between two extreme positions in response to rotation of a driving wheel and a pinion engaging the rack. The pinion is coupled to and drives the oscillating hook. The pinion may have a variable radius, may be coupled to the driving wheel through other racks and pinions, and may be coupled to the driving wheel through a multiple bar linkage. A constant rotation speed of the driving wheel causes the hook to oscillate at a rotational velocity that varies with rotational position of the hook so that swing amplitude of the needle transverse to the linear direction may be increased.

    摘要： One limb of each loop which is formed by the needle thread in an oscillating hook type sewing machine is temporarily in contact with the loop-engaging member of a braking device whose torsion spring is non-rotatably installed in the hollow mandrel of the hook. The loop-engaging member is turned by successive loops from a starting position, relative to the hook and against the opposition of the spring so that it tensions the loop while the latter is raised by the takeup lever. The spring thereupon rapidly returns the loop-engaging member to its starting position. The loop-engaging member is integral with a loop catcher which intercepts the loop when the latter is cast off the hook and which ensures that the loop comes in contact with the loop-engaging member.
