Abstract: 403,533. Reeling-machines. GUSEO, C., and RAVASIO, V., Villanuova Sul Clisi, Brescia, Italy. Feb. 2, 1933, No. 3257. [Class 120 (ii).] Reeling-mechanism comprising cross bars 4 on which the hanks are wound, and each of which is mounted on a radially movable spoke 3 of the reel, a locking device being provided to lock the spokes in their extended positions is characterized by the provision of a single control 13 connected with the spokes and locking device in order with one operation to release the locking device and retract the cross bars radially of the reel, or to move the cross bars radially to the expanded position and actuate the locking means to lock them there. The reel is of metal, having a hub 1 with tubular arms 2 to receive rods 3 carrying cross bars 4, and movable in the rods 2 being guided by studs 5, sliding in slots in the arms 2 and engaging in spiral slots 7 in two discs 8 on the hub 1. Two or all of the cross bars carry combs 9, the teeth of one being opposite the slots of another so that each lea of a hank is separated horizontally and vertically from the next lea. These combs enter guides 9<1> when the reel is collapsed. The closing or opening of the reel is effected by the lever 13, Figs. 4, which turns a shaft 15 and is displaced axially with the shaft by means of a spiral slot device (not shown). Rotation of the shaft 15 causes a pin 18 to enter a notch in the collar 19 on the reel shaft 20 to stop the rotation of the reel, and causes a toothed sector mounted on the shaft 15 to enter the groove of the disc 21, so that the disc 21 and the disc 24 to which it is fixed are first moved axially with the shaft 15 to free the studs 5 of the reel from depressions in the disc 24, and are then rotated so that forks 25 fixed to the disc 24 cause rotation of the spokes of the reel to contract them as the studs 5 move in the spiral slots 7. The reel is driven from a vertical shaft 26, the lower portion of which is connected by bevel gears 27 to a main shaft 28. A friction clutch 29 operable by a lever 30 connects the lower portion 27 to the upper portion of the shaft 26. The lever 30 actuates a spindle 30<1> having gear teeth meshing with a rack on the spindle x, which is axially displaceable against spring pressure in both directions, and which has two forks u and y. The fork y extends into a groove in the rotatable cylindrical member connecting the movable elements of the clutch 29 and brake 31. Movement of the fork y therefore disconnects the clutch and applies the brake or vice versa. To stop the reel when a thread breaks or at a certain stage in the work an electro-magnet 32 is provided, the armature of which when the magnet is energized moves into the path of a nose t on the bush w, freely rotatable on the shaft 26, and having an upper helical cam surface coacting with a counter cam surface on the bush v which is slidably keyed to the shaft 26 and urged against the bush w by a spring z. Stoppage of the bush w causes the bush v to move upwardly on the shaft 26 and through the fork u to move the spindle x to disconnect the clutch and apply the brake. To stop the machine on breakage or failure of supply of the thread, the thread passes from the bobbin or cop 51, 511 in the frame 50 up over balanced guides 33 and between slots 361 in a guide rod 331. The tension of the thread raises the weights 38 from the cylinder 38<1> and interrupts the circuit of the magnet 32. Then if one thread, or when the thread guides are connected by a rod all the threads, break, the circuit of the magnet 32 is completed and the machine stopped. To stop the machine at a certain stage of the work, a rod 39 is arranged to be displaced in steps by the winding operation to complete the circuit of the magnet 32 after a definite amount of winding. A horizontal shaft 40 enclosed in a graduated tube 43 has a double crossed thread of channel form and is rotated through a gear 41 driven from a worm 42 on the shaft 46. A carrier 44 is moved in a slot in the tube 43, by means of a fork with flexible points adapted to extend into the thread on the shaft 40. The carrier has a ratchet tooth 46 which after each double movement of the carrier 44 moves a ratchet wheel 47 and hence the two ratchet wheels 48, 48<1> one step. One of the ratchet wheels 48, 481 is connected with the rod 39, according as " tied-up " working or " crossed " working is being employed, and the rod 39 is therefore moved step by step until at the end of a complete operation it closes the magnet circuit and stops the machine. When the rod 39 is restored to the starting position, the ratchet wheels are also restored to their normal positions by means of a torsion spring. To fix the length of each run of the machine, a ring 49 is adjusted in the desired position on the shaft 40. When carrying out " crossed " working, the thread guide 33<1> is reciprocated by means of gears 80, 80<1> operating an eccentric 81 connected by a connecting-rod 82 with the bar 331. The ties for binding the hanks are fed from a spool 54 above the reel around a drum 52 rotated by means of rods 56, 561 by the rod 13 each time the reel is released and expanded. A roller 55 ensures the feeding of the tie which passes on to a concave plate 83 and is cut against a fixed blade 57. A device for discharging the hanks from the reel is also operated from the lever 13. It is formed as a star 84 of stiff wire arranged on guides 86, 87. Manipulation of the lever 13 due to a connection at the joint 99<1> moves a draw bar 98, carrying a tube 99, so that the tube 99 abuts against a toothed and pivoted arm 102 which rotates the shaft 90 to move the levers 88, 89 forwardly, thus causing the star 84 to move along the guides 86, 87 to push the hanks on to the receiving arm 85 simultaneously rotated through the link 93. The return movement of the draw bar 98 as the lever 13 is moved to release and expand the reel moves a draw bar 104<1>, connected by a bell crank 105, and levers 56, 56<1> to a pinion 81 which rotates the roll 52 to feed a new tie, and the star 84 and receiving arm 85 are simultaneously returned to their normal positions. Empty bobbins are conducted by an inclined sheet hopper 94 to a conveyer band 95.
