Abstract: 26,071. MoConnan, C. S. Dec. 20. Machines for making twine; balling.--Relates to machines for spinning, twisting, doubling, winding, balling, the manufacture of cordage, &c., and consists of improvements on the inventions described in Specifications No. 11,147, A.D. 1900, and No. 2013, A.D. 1901. Mention is also made of Specification No. 10,277, A.D. 1902. The capstan pulleys A are small and placed as close as possible to the centre line of the spindle, and the grooves of successive pulleys are placed successively out of line with one another to an extent depending on the pitch of the grooves and the number of pulleys so that the material may lie properly in the grooves. The flyer is driven by the free end of the spindle, which engages with a socket 1 in the flyer head and has a spiral groove in which engages a pin K. The bobbin is dragged and the machine automatically stopped when the end breaks, by the apparatus shown in Figs. 7 and 8. A pulley 2 is fast on the lower shaft 1 and is driven continuously. By its side is a loose pulley 4 driven from a pulley on the traverse shaft, which is dragged round with the bobbin by this twisted material. Between spring and weighted arms 5, 7 pivoted on the loose pulley and passing round the pulley 2 is a drag cord 3, the effect of which increases as the velocity of the pulley 4 increases with the increasing diameter of the bobbin. The arm 7 may carry a weight 18, which, at high velocities, may slide outwards against the action of a spring and thereby increase the drag. When the end breaks, the pulley 4 is no longer driven, the drag cord runs slack, and the tail of the lever 5, which is normally held in the position 8, is moved into the position 8x in the path of a trip lever connected with the stopping and starting gear. The wire-rope arms a of the flyer are provided with a metal sheath b which slides in the fixed or pivoted holder d, Fig. 4. The holder is partly tapered and partly cylindrical, as shown, the opened-out ends of the wire-rope arms being jammed or wedged in the tapered part of the holder. In a modification, the holder is fixed at a suitable inclination on the flyer boss. By these means the arms are prevented from collapsing when the flyer is stationary. The flyer arms may be steadied by brace rods 36. Between the two sheaves 42, 43, which guide the yarn on the arms of the flyer, is fixed a curved shield 41, which protects the yarn and is held in place by clips carrying the sheaves. The Provisional Specification also describes a method of twisting wires to form the flyer arms ; a swivel joint for connecting the flyer arms to the flyer ; the application of a disc or guard at each end of the flyer to prevent the arms thereof, when at rest, from being dragged on to the head of the bobbin ; a method of tempering the flyer arms ; the application of ball bearings to the loose head of the flyer ; a special method of mounting the guide sheaves ; a method of driving two machines placed end to end ; and a screw traverse mechanism.
