540,746. Winding yarns &c. UNIVERSAL WINDING CO. April 26, 1940, No. 7568. Convention date, April 27, 1939. [Class 120 (ii)] In a yarn or like winding machine comprising a rotatable winding spindle, a traversing yarn guide and a member interposed between 'the package being wound and the yarn guide and bearing against the package longitudinally of the spindle, to maintain the guide out of contact with the package, the package-engaging member is mounted so as to be adjustable angularly with respect to the length of the winding spindle so that it can be brought into engagement with the surface of the package along its length. As shown the package-engaging member is in the form of a wire bail 60 having its bent ends 62, 63 adjustably fixed in a bar 65 carried by a pivot 68 at the back 43 of the traverse frame 7 pivoted on the cam shaft 4 and carrying the traverse guide 10 mounted on the traverse rod 35 which is reciprocated with frame 7 by the cam 40; by adjusting the ends of the bail in the bar 65 the position of the bail can be varied in accordance with the shape or taper of the package being wound. A leaf spring 73 secured at one end to the back 43 of the traverse frame, engages a reduced central part of the pivot 48 to control the turning movement of the bar 65 and a loop 78 on a sheet metal member 75 secured to the back 43 guides the yarn to the slot 80 in the thread guide 10 and to the bail 60. The traverse guide 10 is hinged on an arm 52 which is pivoted on a pin 53 in a member 55 fixed to the traverse rod 35 and having a bent top lug 57 engaging the bevelled face of the back 43 of the traverse frame and a pin 82 fixed to the arm 52 engages a slot in the extension 85 of the thread guide and also a slot 91 in a track way 92 hinged on a pin 93 on the back 43 and having a lug 94 engaging a cam track 95 in a member 96 hinged on a stud 15 on the frame 2 and adjustably fixed in position by a bolt and slot 97, 98; as the winding proceeds the inclination of the trackway 92 is varied to form tapered ends to the package being wound and by adjusting the member 96, the taper at the ends of the package can be varied. A starting lever 20, mounted on a rockable rod 21 connected to the starting and stopping mechanism of the machine, has a curved arm 19 formed with a lug 18 adapted to engage a shoulder 17 on a quadrant 14 pivoted on the stud 15 when the starting lever is moved to maintain the machine operative; the quadrant is rocked automatically when the yarn breaks or fails by reason of a lever 26 falling and engaging a rotating wheel 28 on the cam shaft or by an adjustable block 31 engaging a shoulder 29 on the traverse frame when the package is completed, the rocking of the quadrant cuasing the disengagement of the shoulder 17 and lug 18 and allowing a spring or other means to throw the lever 20 and to declutch the drive and apply a brake-shoe 23 to the tapered periphery of a brake-disc 24 fixed to the winding spindle 3.
