    摘要： [Object] To provide a clutch apparatus that can smoothly switch from a clutch engaged state to a clutch non-engaged state, while tooth jump does not occur even with a small-sized clutch apparatus.[Solving Means] A recessed portion 153 is provided in a cam face of a cam 45. A cam shaft 13 is configured to pivot by a predetermined amount as a cam follower 51 is fitted in the recessed portion, and, when the cam initiates to engage the cam follower, it enters a clutch engaged state. A driven side gear 99 is pivoted by a predetermined amount as the cam follower is fitted in the recessed portion and, thereby, a clutch member 93 is rotated by a predetermined amount in a direction in which a toothed portion 94 is spaced apart from a drive side gear 92. In a state where the cam follower is not fitted in the recessed portion, when the clutch member 93 switches its clutch state, at least a portion of a swing locus of the toothed portion 94 of the clutch member 93 maintains a clearance with a gear tooth of the drive side gear 92.

    摘要： Clutch mechanism for use in an automatic feed system includes a lockout device that prevents re-engagement of a disengaged clutch mechanism until such time as reset of the clutch is accomplished. When the clutch is first disengaged a mechanical flag cooperates with a specially configured shaft to prevent shaft rotation until such time when the flag has been urged out of blocking contact with the shaft.

    摘要： A control device for rotary dobbies in which a key has a transverse groove of width equal to the thickness of a control ring with which it cooperates plus the length of travel undergone by the key in its insertion into or withdrawal from radial grooves in a big end of a main crank arm or in a drive shaft. The control ring has an elliptical shape and is fixed onto a operating lever which, pivoted on a minor axis of an ellipse and retained in its rest position by a V-shaped spring, is made to rock to one side or the other about the axis of symmetry of the spring by a pusher rod. The pusher arm is operated by a cam mechanism and moved by a needle selector controlled by a programmer, to act on one of two valleys provided in a rocking sector on an operating lever symmetrically about an axis of symmetry.

    摘要： A shaft control mechanism for controlling a shaft of a weaving machine according to a pattern includes a connecting rod operatively connected to the shaft, a drive element intermittently rotating and standing still in a dead center position, an eccentric disc rotatably supported on the connecting rod, a coupling element connected to the eccentric disc, a device for moving the coupling element into a recess formed in the drive element interconnecting the drive element and the eccentric disc in a coupled position, a controllable locking element securing the coupling element against movement out of said recess into an uncoupled position until the drive element reaches the dead center position along with the eccentric disc, and at least one control element transmitting an external force to the coupling element according to the pattern, required to move the coupling element into the uncoupled position while the drive element and the eccentric disc are rotating.

    摘要： An eccentric ring is rotatably supported between a drive shaft and a connecting rod. Two coupling keys are independently radially movably supported on the eccentric ring. The first key, during a coupling operation, is radially moved by an inner cam and is held in engagement with a groove in the shaft during a 180.degree. rotation thereof. The second key can move radially between positions respectively engaging the groove and an outer cam on an indexing ring and, for a holding-still phase, is moved outwardly by an edge of the shaft groove into an enlargement in the outer cam. Through the second key being in the enlargement and through a cam on the indexing ring which engages a gap between two noses on the eccentric ring, the eccentric ring is held against rotation. When the first key is moved inwardly, an edge of the groove engages it and thus rotates the eccentric ring and the second key, which slides on a ramp of the enlargement and is moved into the shaft groove. The lifting unit operates without springs moving the keys.

    摘要翻译： 偏心环可旋转地支撑在驱动轴和连杆之间。 两个连接键独立地径向移动地支撑在偏心环上。 在耦合操作期间，第一键通过内凸轮径向移动，并且在其180度旋转期间保持与轴中的槽接合。 第二键可以在分别与凹槽和分度环上的外凸轮接合的位置之间径向移动，并且对于保持静止相，轴向槽的边缘向外移动到外凸轮中的放大。 通过第二个键放大并且通过在偏心环上与两个鼻孔之间的间隙啮合的分度环上的凸轮，偏心环被保持抵抗旋转。 当第一键向内移动时，凹槽的边缘与其接合，从而使偏心环和第二键旋转，该偏心环和第二键在放大的斜面上滑动并移动到轴槽中。 提升单元在没有弹簧移动键的情况下运行。
