Filed: 1929-04-06
Abstract: 329,457. British Cotton Industry Research Association, Platt Bros. & Co., Ltd., and Oxley, A. E. April 6, 1929. Building-motions.-In ring and like spinning frames the bobbins are built by imparting to the' ring rail a motion to effect the chase and a part of the lift, say about one half, and by imparting to the spindle rail a lowering motion to effect the remaining part of the lift, whereby bobbins of greater length than usual can be built in frames of approximately normal size. Such bobbins with a long length of yarn are advantageous in subsequent winding, weaving, or knitting operations and permit the direct beaming of warp yarns without intermediate winding, while the long balloon during spinning is advantageous in the production of low twist hosiery yarns. The ring rail is operated by a building-motion lever 19, Fig. 5, ratchet gearing 21, and chain 26, and the spindle rail is operated by ratchet gearing 85, of which the pawl 29 is actuated by an extension 27 from the lever 19, through worm and bevel gearing 42, 43, 45, 46, and shaft 47.
