A spinning-spindle 16 is rotatably mounted in spaced journal and footstep-bearings 15, 20, in a bolster-tube 10, the bearing 20 being carried within a case 21 mounted in resilient bushes 24 located wholly above and wholly below the bearing 20. The case 21 is integral with or attached to spacer sleeves 22, 23, and the bushes 24 are positioned between the sleeves and the bolster-tube inner wall. A screw plug 14, in the base of the bolster tube, supports the bearing 15, which receives a tip 161 of the spindle 16. A resilient pad 17 is interposed between the bearing 15 and the plug 14, and a resilient bush 18 between the bearing 15 and the bolster-tube wall. In an alternative embodiment (not shown) the bearing 15 is carried in a sleeve which extends into the upper part of the bolster tube and has an inverted frustoconical shoulder engaging a profiled nylon washer secured in the bore of the bolster tube. The shoulder may be spring urged towards the washer. |
