Abstract: 560,890. Reeling yarn. GIBSON, W. March 20, 1942, No. 14955/43. Divided out of 500,863. [Class 120 (ii)] In a reeling machine for winding yarn into hanks on a swift 32 by a continuous relative traverse between the swift and yarn-guiding means, the traversing means is driven from the swift-driving shaft and includes a rotary traverse wheel which makes several complete revolutions during the winding of a hank and drives separable toothed members having a tooth pitch or spacing corresponding to a traverse equivalent to a substantial number of windings so that the operator cannot put the traverse rail slightly back to add a small number of windings to a cut or lea ; the primary driving shaft is geared to the swift-driving shaft through a clutch with clutch-operating mechanism which may be controlled manually or by automatic stop means which includes an element held inoperative by a part moving with the traverse rail until the traverse wheel has commenced its last revolution when it is held inoperative by a support rotating with the wheel and is freed thereby as the wheel completes its last revolution to cause disengagement of the clutch when the hank is exactly completed. As shown, the shaft 3 of the swift is driven by reduction gearing 4, 5 from the primary driving shaft 1 and a clutch 7, 8 is disposed between the shaft 1 and the gearing 4, 5 ; the clutch may be actuated by movement of a bar 14 carried by arms 16 fixed to a rockshaft 17 to which is also fixed an arm 18 connected by a spring-link 20, 21 to an arm 22 on a shaft 12 carrying the fork 10 actuating the movable member 8 of the clutch 7, 8. The automatic stop-motion for disengaging the clutch when a predetermined number of windings have been made, comprises a rod 41 held clear of a cam 40 on the shaft 3, while winding is taking place, by a lever 43, to which the rod 41 is pivoted, the lever being loose on the shaft 17, and having a hook 44 engaging under a rail 45 on the traverse rail 29 which is traversed by a rack 55 actuated by a pinion 54 on a shaft 58 driven by worm gearing 61, 62 from the shaft 63 of the traverse wheel 46, driven by a worm on the shaft 3. Near the completion of the winding the hook 44 becomes disengaged from the rail 45 and allows the rod 41 to fall, a bracket 49 thereon engaging a support 48 rotating with the traverse wheel until the wheel completes its last revolution when the rod is engaged by the cam 40 and lifted so that a pawl 50 on the lever 43 engages a member 52 fixed to the shaft 17 and rotates the latter to disengage the clutch and stop the machine ; a brake for the shaft 3 may be associated with the stop mechanism. The shaft 58 is slidably mounted on brackets 60 and is connected by a feather to the pinion 54 so that, by releasing a pivoted latch 64 from a collar 66 on the shaft, the shaft may be pulled forward to disengage the separable toothed members 61, .62 and reset the traverse rail to its initial position, the shaft 58 then being pushed back to its original position with the worm gearing in correct alignment so that the rail cannot be moved slightly to correct a supposed lack of windings in a cut or lea. The rod 14 extends above the bobbins and yarn-guiding means and serves to protect them. The traverse bar 29 carries a pointer 34 co-operating with a scale on a fixed rail 25 to indicate the progress of the winding.
