Abstract
722,849. Double-twist spindles. LANDOLT, K. Aug. 14, 1950 [Oct. 11, 1949], No. 19309/52. Divided out of 722,404. Class 120 (2). A double twist spindle comprises a freely joumalled normally stationary unit having a periphery formed to provide a thread guiding surface; a fixed member disposed externally of the stationary unit and spaced a predetermined distance from at least a portion of the peripheral surface oi said stationary unit tc provide a gap for the passage of the twist balloon formed by the thread a portion of the stationary unit projecting outwardly a sufficient distance to engage the fixed member upon limited rotational movement of the stationary unit. As shown in Fig. 2, the shaft 18 is rotatably supported in casing 19 secured to frame 21. A disc 22 is secured to shaft 18 and has a lower portion in the form of a pulley 23. Above the disc 22 the shaft carries two ball bearings 24 on which stationary part 25 is supported. Said stationary part 25 supports a bobbin 26, has a thread guiding surface 27 and carries a soft iron armature 31 positioned opposite a magnet 30 supported in an arm 28 and having a cover 29. The peripheral surface 27 of the stationary part 25 is arranged to have some part of it eccentric with respect to the axis of the spindle so that should rotation of the normally stationary part be caused, the eccentric portion contacts the arm 28 and prevents complete rotation. The surface 27 is preferably made up of several conical surfaces at least one of which is eccentric with respect to the spindle axis.
