Abstract: 27,792. Eigenbertz, J. H. H., a n d Duckett, Morrison, & Co. Dec. 3. Winding-machines; driving-arrangements; creel arrangements; thread-guides; tension arrangements; stop-apparatus, non-automatic; stop-motions; doffing- arrangements.-The yarn guides of a machine for winding yarn and thread into cops are carried on a vertically sliding frame 25 connected by chains or flexible ties to a shaft 35, which is operated to effect the building by means of a chain 36 connected to a ratchet-operated building-motion on a lever 40 actuated by a cam 19<Î>. The machine is built in sections each of which may contain one or more spindles, and each section is driven independently by means of a clutch, which drives the tin roller through chain gearing and the traverse cam through circular or elliptical wheels. The lever 40 is pivoted at 41, and the building-mechanism is arranged at its outer end, so that it is kept in contact with its cam by gravity. A bowl 44 or one of the guidebowls is mounted on a lever which is operated by a cam to deflect the chain and thus to cause a quick descent of the yarn at the nose of the cop. The chain 36 is attached to a stop on a wheel 55 and passes around a removable and adjustable block 56, so that as the wheel 55 is rotated by a ratchet pawl 57 and an adjustable stop 60 at each reciprocation of the lever, the chain is wound around the block. The ratchet pawl 57 and a holding-pawl 61 are simultaneously released by a catch lever 63 to allow the carriage to be lowered when the cops are completed, and, to allow of underwinding, the chain 36 is further released by the movement of a lever 67 carrying a bowl 38 when this lever is released by the catch lever 63. The yarn guides comprise wires 3 fitted with glass sleeves, and the yarn is led thereto from below by a wire 29, Fig. 19, to facilitate the quick downward movement by reducing the pull on the supply. The wire 29 may be pivoted so that it may be operated to move the yarn behind the spindles to facilitate doffing. The carriage 25 may be provided with depending rods sliding in bearings, or may slide on fixed rods, and is provided with cushioning-springs. The creel comprises a series of pivoted sectors 71 each carrying three skewers, a guide 75 being provided with a stop so that the sectors may be held in position during recharging. The clutch for driving the shaft 5 comprises engaging cones, disks, or, as shown in Fig. 11, conical bowls 16 mounted on pins on the movable member 15 and adapted, when the clutch is put into gear, to move outwards along their pivots into engagement with brake blocks 17<Î> on the member 15, so that their free rotation is gradually prevented, and motion is transmitted to the driven disk 14. The member 15 is connected to a slotted disk 6 fast on the shaft by pins 9, and is operated by a spring rod 78 carried on a lever 76, which is normally held by a catch lever 82. The lever 82 may be released by hand, or automatically upon breakage by means of a pivoted guide which operates a frame carrying the fulcrum of the lever 82. The rod 78 also operates to apply a brake to the tin roller. In the Provisional Specification, it is stated (1) that each section may be driven through a kind of differential motion in combination with a brake arranged so that the mechanism is driven when the brake is applied, and the planetwheel cuse turns loosoly when the brake is released, and (2) that the nosing-motion may comprise a fixed peg against which the building-chain swings, and may be utilized for the top or bottom of the chase, or for both.
