Abstract: 9311. Herbst, H. W. April 20. Machines for making.- In a machine for simultaneously spinning or twisting hemp, cotton, or other yarn, and balling it when formed into string or cord, the yarn is passed round any suitable twisting - device such as a, Fig. 1, round a guide pulley a<1> to a pulley b and then round a second guide pulley a<2> and along a hollow spindle c to the flyer arms d. The flyer arms d are mounted on a disk d<1> driven by a pulley g on a sleeve g<1> surrounding the hollow shaft c. A second disk c<1> driven by friction from the disk d' is secured to the shaft c, and its rim c<3> is formed as a face cam, a second relatively adjustable annular cam c', of similar shape but of opposite hand, encircling it. On this compound cam run rollers d<3>, Fig. 2, operating levers d<2> connected by links d<4> with the ring e, which is pivoted to the flyer arms d, and which is oscillated so as to lay the yarn, which runs round guide pulleys a<3>, a' on the flyer arm, and a<5> on the ring, on to the ball F. During the early stages of the winding of the ball, the cams c<3>, c<4>, Fig. 4, are arranged to present, as a compound cam, an even rise and fall, but for the last few layers, in order to impart to the ball a marketable appearance, the cam c<4> is moved relatively to the cam c<3> through one-eighth of a revolution, so that the compound cam presents a level portion for three-eighths, a rise for one-eighth, a level portion for threeeighths, and a fall for one-eighth. The speed of the rotation of the disk c<1> is regulated as balling proceeds by the yarn passing round the weighted pulley b, the carriage b<2> of which runs on rails b<3>, Fig. 12. As the ball increases in diameter, the tension of the yarn increases and tends to drag the carriage b<2> up the rails b<3>. This rotates a shaft b<4>, connected to the ends of the rails b<3>, to loosen a brake-band b<1> on a pulley c<2> on the shaft c, and thus allow the shaft to increase its speed and reduce the tension. The balling-arm f is rotated at the same speed as the hollow spindle c, and, to ensure that each successive diagonal winding shall be in its proper position, the balling-arm is fed forwards relatively to the spindle c a slight amount at each rotation of the flyer arms. To accomplish this, a spur-wheel h, secured to the disk d<1>, drives a second spur-wheel h<1> through pinions h<2>, h<3>, one each end of an axle carried by the disk c<1>, at the same speed as the disk d<1>. The spur-wheel h<1> carries an arm h<5>, Fig. 6, provided with a spring-controlled pawl h<6> and a roller h. The pawl h<6> engages the teeth of a ratchet-wheel loose on the spindle c, and the roller runs on a crescent-shaped member h<8>, so arranged as to mask the teeth of the ratchetwheel and only allow the pawl to be in operation for a portion of a revolution. A ring i with a recess i<1> co-operates with the member h<8>. The ratchet-wheel j is provided with crown teeth j<2>, which mesh with a bevel-gear j<3> on a radial spindle j<4> carried in a frame j<5> secured to the spindle c<1>. The spindle j<4> drives, through bevel-gearing j<7>, a worm j<8>, which engages with internal teeth j<9> on a hood j<10>, which carries the balling-arm f. As the ball increases in diameter, a greater number of diagonal windings are necessary to cover it, and the relative movement between the balling - arm and the spindle c has to become smaller as the ball gets larger. To accomplish this, an intermittent relative movement of the member h<8> and the gap i<1> in the ring i is provided, to decrease the effective number of teeth on the ratchet j at each revolution of the spindle c. The hood j<10>, Fig. 9, carries a projection j<5>, which operates a lever i<3> pivoted to the disk c<1> and causes a spring-controlled pawl i<9> to engage with ratchet teeth i<2> formed in a gap in the ring i, and to move the ring i relatively to the crescent h<8>. If two or more layers having the same number of diagonal windings are to be wound, the pawl i<9> is held out of operation intermittently by a lever i<14> operated by projections i<11> on every second, third, &c. tooth of a ratchet wheel i<12>, which is rotated by a pawl i<4> from the lever i<3>. A bell-crank lever i<15> is provided to engage with a projection i<18> on the pawl i<9> to allow the ring i to be rotated by a handle i<19>; it also has a projection i<16> adapted to engage with the teeth i<2> on the ring so as to lock it in any adjusted position.
