Abstract: 12,673. Leeson, J. R. June 17. Balling cords, twine, &c.-Reference is made to Speci6caticns No. 6497, A.D. 1892, and No. 6381, A.D. 1893, [both in Abridgment Class Spinning]. The machine is specially applicable for winding heavy cords, twines, &c. The speed of rotation of the winding- spindle and the speed of the reciprocating threadguide remain the same for oops of different sizes the length of the cops and the number of turns in the length of the same being regulated by adjusting the length of the traverse. The curved thread-guide I is mounted on a carriage J traversed by a screw D, the rotation of which is reversed at each reciprocation by means of an arrangement of three bevel-wheels 29, 31, and 32, of which 29 rotates uniformly and 31 and 32 run loose and are brought into action alternately by means of clutch mechanism 33. The clutch fork H is carried by a sliding rod c held in its extreme positions by a bevel catch t, the action of which is only overcome when the pressure between a stop 70 on the carriage J, and a sliding spring stop 47 on the rod has reached a certain maximum. In a modification, the rod c is held by a catch until the latter is released by the direct action of a stop on the carriage J, when the rod is moved longitudinally by a spring, for adjusting the length of the traverse to a small fraction of a turn of the winding- spindle ; the adjustable stop G is made in two parts g, h, of which g slides on the rod c and is secured by a set-screw, while the second part h is adjustable on the first by screwing and is secured by a lock-nut h<1>. The traversing-screw may have more than one thread. The cord passes from the supply bobbin S over a guide-pulley 23, other guide-pulleys 51, 52, a tension pulley N, another guide-pulley 15, and thence over a curved guide n on the weighted frame F, which carries the traversing- guide, to the winding- spindle. The machine is stepped and started by the longitudinal motion of the spring rod 21, which is held in the position required with the strap on the part pulley by means of a spring catch, to release which a slight rotation of the rod 21 is required. This rotation may be brought about by means of a handle, by means of the wound cord, which, when the cop has attained a sufficient diameter, engages with a lever 37 on the rod 21 ; by means of a lever 22, which is depressed when an entanglement occurs in the cord being wound ; and also when the cord breaks or fails, the stoppage in this case being effected by means of a spring lever 14 carrying the guide-pulley 15, the lever 14 being provided with an eye 2U which, when the lever falls, engages with a stop 19 on the rod 17 connected with the lever 22. The tension pulley N is pressed downwards upon a table M by means of a disc 56 and weighted lever 54, the underside of the disc and the upper face of the table being preferably covered with leather &c. The tension pulley may be in two parts, each having a hub and rim connected together by ribs, the ribs on the one part taking between those on the other. As the cop increases in diameter, the frame F carrying the traversing-guide turns about the axle 26, but is prevented from returning towards the spindle after having been once moved away by means of a curved rod and cam Q, P. In a modification, the screw of the reciprocating guide is driven through an expanding pulley, so that the relative speeds of the spindle and guide may be varied. The expanding pulley, Fig. 19, is adapted to be driven by a flat belt, one or more incomplete or split bands 73 being attached by one end to one or both of the conical parts 60, 61 of the pulley. The part 60 is fixed, and the part 61 is secured in position by a split nut 74 on the second end of the shaft. The adjustable part 61 may be made in one piece with the split clamping-nut, which is clamped on the screw-threaded hub of the fixed part.
