Abstract

400,590. Spindle driving arrangements for spinning or like machines. WHITIN MACHINE WORKS, Whitinsville, Massachusetts, U.S.A. April 22, 1932, No. 11584. Convention date, May 1, 1931. [Class 120 (ii).] In a spinning or twisting machine comprising a frame 10, Fig. 1, having a plurality of spindles 13 mounted along each side thereof, and a driving cylinder 12 for said spindles mounted in the frame, bands are provided for driving the pulleys, each band having a straight run across the machine and under the driving cylinder and an indirect run which is looped upwardly into driving engagement with the cylinder. Each band passes round pulleys 64 over pulleys 65 and around the underside of the cylinder 12. As separate pulleys 64, 65 are provided for each band and these pulleys are entirely open at one side, this construction permits a continuous band D woven in one piece to be employed and to be easily placed in position. Each pulley 64 is mounted on an arm 66 pivoted on a hub 67 and counterweighted by a weight W so that the belt D is tensioned by the pulley. Inward movement of the arm 66 is limited by a lug 70 and stop 71. The upper guide pulleys 65 are mounted on arms 75 secured on rods 76 by screws 77 and may be adjusted to suit the length of the band D. The Specification as open to inspection under Sect. 91 comprises also a motor M adjustably mounted within the base portion of the frame, and connected by belts 22, Fig. 1 (Cancelled), to the cylinder 12, the motor being mounted upon a support normally rigidly fixed to the frame but vertically adjustable thereon. The support comprises end frames 39 slidable vertically in guideways in the frame 10 and adapted to be secured in a vertically adjusted position by bolts 41. Bars 37 secured in depending portions 38 of the brackets 39 support members 31 which have slots to receive the clamping bolts of the motor. A nut 44 with an enlarged head 45 is mounted in each bracket 39 and receives a supporting screw 50 depending from the spindle rail 11. Openings 52 permit rotation of the nut 44 to adjust the motor M vertically to tension the belts 22. The pulley 21 on the motor drives by the belts 22 the pulley 23 on the shaft 24 of the cylinder 12, the drive being enclosed by a casing 25. Bands 17 pass over the cylinder 12 and each drive two spindles. Each band has a straight run across the machine under the cylinder 12 and then passes round the spindles, around guide pulleys 18 and over the cylinder 12. This subject-matter does not appear in the Specification as accepted.
