Abstract: 10,211. Forsyth, W. G. July 14. Spindle apparatus; building-motions; winding-on motions; driving-arrangements.-In a continuous spinning, doubling, or like machine, the yarn, thread, &c. is wound upon a spindle revolving in fixed bearings by a stud or hook on a ring or small pulley, which acts as a flyer and which is carried by a vertically reciprocating rail. The pulley is driven and the rail is reciprocated by means of duplex oscillating traversing quadrants and reciprocating shaper plates operating on the principle of the mule to wind a cop upon a bare spindle or on a tube thereon. The spindles 14, Fig. 2, are mounted in ball bearings at each side of the machine and are driven by tin rollers 16<A>, 16<B>, the former of which is carried by the driving-shaft 18<A>. The rings or pulleys 1<B> carrying the studs 1<A> are driven by a second pair of tin rollers 15 and are carried along with the tin rollers by a rail 4, which is guided by vertical pokers and sleeves. The rail 4 is suspended by chains 6 from sectors 7, to which an oscillating movement is imparted to cause the reciprocating movements of the rail. The tin rollers 15 are driven by a pair of endless ropes 19 passing over pulleys 17 loose on the driving-shaft, round pulleys 20 fixed on the shafts of the rollers 15, then round adjustable fixed pulleys 29, and back to the pulleys on the driving-shaft. The pulleys 17 are driven through a differential motion of the Curtis and Rhodes type, which has one element controlled by the oscillating quadrants described below. The rock-shafts 8 carrying the sectors 7 are controlled by levers 9 operated by a cranked poker 28 keyed to a second poker with prongs 26 sliding in fixed bushes 25. Legs 23, having at their lower ends bowls 33 resting on rails 52<A>, Fig. 3, are fulcrumed on a stud-piece 27 carried by the poker 28. The inclines of the two rails are in opposite directions, and springs 24 bear on the legs and press the bowls against the inclines. The rails 52<A> are worked on the principle of the short shaper rail of a mule and are supported by plates 52<B> working in slides in a reciprocating table 53. The plates are adjusted as the cop grows, by a screw 54. The table 53 is guided by rods 55 engaging holes in depending flanges at the ends, and is reciprocated by means of a bar 46<A> provided with a friction surface underneath, which is kept, by bowls 45, in contact with one of two equal semicircular wheels 47<A>. These wheels are carried on equal intermeshing gears 47<B> driven through worm and bevel gearing 49, 50 and cone pulleys 51 from the front-roller shaft 11, which is in gear with the main shaft. The bar 46<A> supports a quadrant bar 37, having at each end blocks which slide on rails 37<c> and through which the tin-roller shafts 18<A>, 18<B> pass. A gear 43 loose on the bar 37 engages a stationary rack 44 and, as the bar 46<A> reciprocates, rotates a quadrant 40 through gears 41, 42. The quadrant 40 operates two arms 38<A>, 38<B>, which, through chains 39<A>, 39<B>, rotate drums 31 on spindles 32 carrying bevelgears, which rotate a gear loose on the main shaft and, through the Curtis and Rhodes differential gear, control the rotation of the rope pulleys 17 which drive the tin rollers 15. The two quadrant arms operate alternately, and the chain that is not in tension is wound up by a weight or spiral spring. The quadrant bars comprise worms and nuts 71, the worms being turned to move the nuts by bevel-gears 63, 65 controlled through a change-wheel by a ratchet device operated by the reciprocating movements of the quadrant bar. The two worms are geared together by skew bevels 66. The ring or pulley 1<B> runs in a ball bearing fixed in the reciprocating rail 4. The wall of the ring 1<B> rises above the bearing, whilst the bearing extends below the ring to shield the cop from injury by oil when lubricating. The bar 46<A> may be hinged to the table 53 or may impart movement thereto through racks 58, 59 and gears 61, 60 on a fixed stud. The rack 58 is fixed to the bar, and the rack 59 to the table.
