Abstract: 106,860. Collins, C. H. June 6, 1916. Yarns, beaming; yarns, measuring.-Winding- apparatus for use in Axminster tuft-yarn pattern setting-frames comprises tension rollers, which serve also as measuring-rollers and between which the yarns pass from a reed for ensuring the proper relative positions of the yarns, spring means for regulating the tension exerted on the yarns by the rollers, and a measuring stop-motion device for locking the tension and measuring rollers when a predetermined length of yarn has passed between them ; a yarn pressing-device and means for stopping the rotation of the spool also are provided. As shown, the yarns A, Fig. 2, pass through a reed C, between tension and measuring rollers B, of which the lower is preferably iron and the upper is covered with rubber, and through a reed D to the winding-spool E. The rollers B are rotated by the yarns. To the shaft G, Fig. 8, of the lower roller is secured a disk H with a flat J adapted to be engaged by a lever K, which has pivoted to it an arm K<1> with a projection k adapted to engage a notch N in a disk M on a shaft L. The shafts G, L are geared together by toothed wheels, that on the shaft G having, say, twenty-five teeth and that on the shaft L twenty-four teeth, so that the disks II, M come simultaneously into position to be locked by the lever K, and the projection k only after a definite number of revolutions of the rollers B, the lever and projection normally riding on the edges of the respective disks. To disengage the lever K and projection k, a hand-lever T<3>, loose on the shaft G and acted on by a spring T<2> attached to a handwheel T. is moved to cause a stud I thereon to engage a cam-surface J' on the lever K, which is thereby raised and acts on the arm K<1> to raise the projection k from the notch N. When the lever T<3> is released, the spring T<2> returns it to its normal position with the stud I in contact with the spoke 20 of the wheel T. The spool E rests on and is rotated by driven rollers R, and a presser-roller S rests on the yarn. The roller S is pivotally mounted by brackets s, Fig. 3, on a frame U so that it can be turned to one side to remove the spool E. The frame U is pivoted at y to slidable rods V, V<1>, of which the rod V<1> is pulled downwards by a spring to cause the roller S to exert pressure on the yarn. The roller S is driven by a chain 12 passing over sprocketwheels 13, 15, 20 at the ends of toggle-levers 23, 24, the wheel 20 being driven by gears 17, 18 from a shaft 19 provided with universal couplings 26, 27 to allow vertical movement of the roller S. The shaft 19 is driven by a chain 35 from the driving-shaft 37, which has a loose pulley 39 adapted to be made fast by a clutch 38 and operating-lever 56. This lever is attached to a slidable rod 54, Fig. 4, which enters a spring-pressed sleeve 52 and is connected by a link 62 to a starting and stopping lever with treadles 60, 61. A lever 43 is connected by a chain 41 to the free end of the arm K<1> and is normally held by a spring 47 in a notch in an extension 45 of the sleeve 52. When the projection k enters the notch N, the disk M acts on the arm K<1> to raise its free end against the action of a spring 49, so that the lever 43 frees the sleeve 52, which is thereupon moved by the spring 51 and acts through the rod 54 and the lever 56 to unclutch the pulley 39 and stop the winding-apparatus. To put tension on the yarns passing between the rollers B, a rod 160 is screwed an adjustable distance into a block 161, connected with the bearing of the upper roller, and is secured by a jamnut 163. The rod 160 is movable through the end of a curved arm 100, and a spring 164 is confined between the arm 100 and a collar 165 on the rod to cause pressure between the rollers. The upper roller may be freed from the lower roller by turning a counter weighted cam-arm 101 on a shaft 102.
