Abstract: 539,657. Treating thread &c. of artificial silk &c. INDUSTRIAL RAYON CORPORATION. Dec. 18, 1939, No. 32457. Convention date, Dec. 27, 1938. [Classes 2 (ii) and 15 (i)] [Also in Groups IX and XIII] A reel for winding and delivering thread or the like, e.g. of artificial silk, is rotatably mounted on a supporting member which is detachably secured in the frame of the threadprocessing machine, the driving means for the reel being disposed adjacent one of the ends of the supporting member and the frame having means to hold the end of the supporting member adjacent the driving means rigidly in place and an opening to permit the passage of the driving means therethrough. As shown the reel comprises two sets of inter-engaging bars 19, 20 carried by reel members 21, 24 respectively, the member 21 being carried by a driven shaft 15 detachably mounted in the frame 11 and the member 24 being secured to a flanged member 27 carried by ball bearings on the supporting member 23 so that the axes of the members 21, 24 are inclined to each other in offset parallel planes. The supporting member 23 is formed with a flange 62 having edges 63, 64 engaging correspondingly shaped surfaces in the recess formed by a cup member 65 secured in the frame 11 for accurately locating the reel in the frame. The member 65 is formed with lugs 72 carrying set screws 73 having conical ends engaging the tapered portion 75 of the flange 62 and securing the member 23 and reel members in the operative positions in which the bevel pinion 14 on the shaft 15 engages a pinion 13 on the driving shaft 12 serving a number of reels arranged in a tier on the inclined frame 11 ; the shaft 15 drives the reel member 21 which drives the reel member 24 through the inter-engaging bars which advance the turns of thread thereon from the supported to the unsupported end of the reel, from which the thread passes to the reel beneath it for further processing. The member 21 is driven from the shaft 15 through a ball clutch 51 which permits relative rotation between the shaft and member 21 in the event of an increase of torque beyond a pre-determined amount ; the clutch also serves to locate the member 21 lengthwise of the shaft. The member 24 is secured to the flanged member 27 by T-headed'bolts 28 having the heads shielded by a flange 30 formed on the member and extending over the bars 19 to prevent the thread from becoming entangled with the rear of the reel. A flexible seating member 32 extends between the two reel members. The ball bearings 39, 40 supporting the flanged member 27 on the supporting member 23 are packed with lubricant and have their outer ends sealed, and lubricating material may be placed in the space between their inner ends. The member 23 is supported on the shaft 15 by a ball bearing 46 packed with lubricant and a sleeve 47 of lubricant-impregnated metal keyed to the member 23. Lubricant may also be stored inside the member 23 between the bearings, or the sleeve 47 may be replaced by a needle bearing. The thread in passing along a reel is treated by a processing liquid supplied from a pipe 3 communicating with a conduit 4 extending across the machine, and the liquid from the reel drops into a collecting trough 5 also extending across the machine, the conduits and troughs being moulded from a resistant material and being mounted on flanged plates 77 secured to the frame 11, and each trough having an opening provided with an apertured cup-shaped member 82 through which the supporting member 23, gear 14 and flange 62 are passed in connecting or disconnecting the reel. A flange 84 on the hub of the flanged member 27 prevents liquid from passing along the hub to the rear bearings. In a modification the supporting member 23 is extended to form spaced side members enclosing the gear 14 and supporting compartments connected to lateral pipes which, respectively, supply a heating medium to the reel through a pipe disposed in the shaft 15, which is made hollow, and remove the medium from the hollow shaft. Specifications 413,414, [Group IX], 474,973 and 537,382, [Group IX], are referred to.
