Abstract: 369,669. Supplying cotton &c. to hopper feeders, openers, &c. RUSHTON, J. L., Kay Street Works, and SCHOFIELD, C., 63, Knowsley Road, Smithills, both in Bolton. Dec. 31, 1930, No. 39289. [Class 120 (i).] Apparatus for supplying fibrous material such as cotton during preparation for spinning, and comprising a feed chamber 10, Fig. 1, fed from a main supply conduit 64, Fig. 4, and serving as a common supply for a number of branch conduits 16, 17, each feeding a manipulating machine, and feed regulating means comprising a control-member 23 responsive to the quantity of material in the feed chamber 10 and/or branch conduits and having an operative connection 52, 53 to a supply-varying device 66 for the main conduit 64 whereby the member 23 automatically controls the supply of material to the inlet of the chamber 10 in accordance with the total requirements of all the machines fed therefrom is characterized in that distributing means, such as two rolls 20, 21, spaced apart about the control member 23, is arranged in the chamber 10 to maintain the material distributed among the outlets. The bladed distributing rolls 20, 21 are driven in opposite directions by pulleys 27, 28, Fig. 2, and feed the material in opposite directions over the control member 23 to the outlets 14, 15 for the branch conduits 16, 17. The member 23 is formed as an inverted V having depending skirts 31, 32, and is guided by rollers 36, 38 to move vertically between the outlets 14, 15. 'The apex of the member 23 is supported by a rod 42 extending through vertical slots 43 in the side walls of the chamber 10 and is connected by links 46, 47 to counterweighted levers 44, 45 having hooks 50, 51 connected by wires 52, 53 over guide pulleys 54, 55 to the supply-varying device 66, which, as shown in Fig. 4, comprises a change-speed gear associated with a hopper feeder 67. The hopper feeder 67 may deliver to one or more openers and thence to a pneumatic delivery box 65 and mouthpiece 12. The cotton then passes by the branch conduits 16, 17 to the horizontal openers 68, 69. Alternatively, the branch conduits may supply hopper feeders feeding vertical or horizontal openers. When the supply is normal the member 23 is in the upper position in the chamber 10, the cotton being scattered by the rolls 20, 21 and distributed by the member 23 through the outlets 14, 15 into the conduits 16, 17. As the conduits 16, 17 become full material accumulates below the rolls 20, 21 pressing the member 23 downwards, the wire control mechanism 52, 53 then operating the device 66 to reduce or stop the feed, i.e. material ceases to be delivered to the conduits 16, 17 until, some being used, the pressure is relieved, the member 23 ascends and the control 52, 53 restarts the normal feed. If one conduit 16 or 17 becomes full before the other, material which is passed underneath the feed roll at the inlet will be carried round by the roll and thrown towards the other branch so that the control member 23 does not operate until both branch conduits are full. The feed rolls 20, 21 may in certain cases be omitted.
