    摘要： A hook assembly includes a bearing rib on a bobbin case basket or at least a surface layer thereof composed of a synthetic resin, such as a liquid crystal polymer, which has properties such that the amount of the rotating friction generated between such surface layer and an inner surface layer of a groove shaped bearing raceway in which the bearing rib is fitted is lower, with no industrial sewing machine oil therebetween than such industrial sewing machine oil where to be provided therebetween. The hook assembly thus has good durability without any lubrication being provided. Accordingly, oil staining of threads and sewing materials by a lubricant is avoided, and sewing quality is enhanced.

    摘要： A rotary looptaker includes a looptaker body rotatable about a vertical axis and a bobbin case restrained from rotary motion with the looptaker body. A plurality of annular protrusions are provided on a flange of the bobbin case so as to extend in a circumferential direction of the bobbin case and are in engagement with a flat surface formed on a raceway of the looptaker body. When the looptaker body is rotated, the bobbin case slides relative to the looptaker body through a very small contact area between the annular protrusions and the flat surface, thus reducing sliding friction between the looptaker body and the bobbin case. Accordingly, noise and vibration are decreased when a rotation restraining projection of the bobbin case contacts a restraint element secured to a machine frame.

    摘要翻译： 一种旋转打纬器包括可围绕竖直轴线旋转的吸收体，以及与吸收体相对应的旋转运动的梭壳。 在梭壳的凸缘上设置有多个环形突起，以便在梭壳的圆周方向上延伸并且与形成在吸收体本体的滚道上的平坦表面接合。 当吸收体旋转时，梭壳通过环形突起和平坦表面之间的非常小的接触面积相对于吸收体主体滑动，从而减小了吸收体与梭壳之间的滑动摩擦。 因此，当梭壳的旋转抑制突起接触固定在机架上的约束元件时，噪音和振动减小。

    摘要： A rotary hook (1) of a lockstitch sewing machine composed of at least one hook body (2) includes a cylindrical cavity (11) and a basket (6, 6b) free to rotate in the cylindrical cavity (11), a bobbin case (8, 8b) housed in the basket (6, 6b) and a bobbin (4, 4b) housed in the bobbin case (8, 8b), elements (30, 40, 50, 60, 61, 70,) suited to create a friction between the bobbin case (8, 8b) and the basket (6, 6b), so as to prevent the bobbin case (8, 8b) to move freely and to vibrate within the plays present between the bobbin case (8, 8b) and the basket (6, 6b) and to consequently reduce the noisiness created during the sewing operation.

    摘要： Disclosed is a rotary shuttle device for a sewing machine, in which an outer shuttle is comprised of three separate constructing elements so that only an excessively worn portion or a portion that requires replacement is selectively replaced. The outer shuttle comprises a main body (32) integrally provided with a base portion (34) which is disposed at the driving shaft, a first supporting portion (36) which is protruded at one side of the base portion (34) to have a first partial track groove (40) on an inner face thereof, and a second supporting portion (38) which is protruded at the other side of the base portion (34) to be opposite to the first supporting portion (36) and have a second partial track groove (42) on an inner face thereof; a track groove member (50) which is removably disposed between the first and second supporting portion (36, 38) and has a third partial track groove (52) communicated with the first partial track groove (40) of the first supporting portion (36) and the second partial track groove (42) of the second supporting portion (38); and a groove member (58) which is removably fixed to the second supporting portion (38) of the main body (32), and formed with a pointed end (66), a groove (64) through which the under thread wound on the bobbin is passed while being contacted therewith and a fourth partial track groove (60) communicated with the second partial track groove (42) of the second supporting portion (38).

    摘要： A Cardan gear assembly wherein rotary input motion of the main shaft is converted to elliptical output at the Cardan gear output centerpoint. The Cardan gear output centerpoint is connected via a ball and a pin slideable therethrough to a support having a work performing instrumentality arranged at its distal end. During operation, the elliptical output motion of the Cardan gear output centerpoint is transmuted into three dimensional, elliptical like motion at the tip of the work performing instrumentality.
