257,498. Joyce, J. D. April 28, 1925. Winding-machines; stop-motions; spindle-driving apparatus; stop-apparatus, non-automatic.- In a traverse mechanism for a winding-machine, the traverse arm which reciprocates the threadguide is driven from a rock-shaft by a clutch which is disconnected when the bobbin is fully wound, or when the thread breaks. The drive shaft 1, Fig. 1 drives a countershaft which is journaled in a casing 1<a>, and carries a cam which actuates rock-shafts 8. Frictionwheels 9 on the shaft 1 drive wheels 10 slidably keyed to shafts 11 which carry cop-spindles 12. An arm 20, Fig. 3. which is rocked by the shaft 8 through a clutch 17, reciprocates a bar 22 which actuates bars 23, 24, the former of which carries a shaper plate 26. A screwed threadguide rod 25, Fig. 1, slidably pivoted at one end 82, is pivoted to slide laterally at its other end in a slotted plate 28 on the rod 24. The thread-eye 14<a> is fixed to a spindle 41, an arm on which carries pins embracing the arm 44, Fig. 3, carrying the eye 14<b>. On a stud 45, Fig. 3, is slidably journaled a collar which carries the arm 44 and an arm 46. If the thread breaks, the thread-eye in use falls and rocks the, arm 46 into position between a collar 47 on the reciprocating rod 24 and an arm 49 fixed to a stud 48. The relative positions of the parts are such that on its next reciprocation the collar 47 forces the arms 46, 49 to the right, so that a collar 50 fixed to the stud 48 passes from under an arm 51 on a spindle 18. An arm 55 on the spindle 18 thereupon disengages the clutch 17 to stop the reciprocation of the rod 25. An arm 69 on the spindle 18 is also lowered to allow an arm 61, Fig. 5, on a stud 60 to be rocked by a spring 52. A hooked arm 64 on the arm 61 thereupon rocks a clutch-member 66 on the shaft 11 against a weight 70, Fig. 1, to allow a brake-arm 62 on the stud 60 to slide the wheel 10 away from the wheel 9, against springs 77, and stop the wheel 10 and the spindle 12. When the cop is fully wound, an arm 75 on the thread-guide carrier engages an arm 76 on the spindle 41, Fig. 1, to rock the spindle and so stop the rod 25 and the spindle 12. By the action of the shaper plate 26 the cop is built up with conicity at both ends. The spindle 41 may be manually rocked to stop the mechanism. In a modification for building a cop which is cylindrical at the starting end, the members 22, 23, 24, 26, 28, are dispensed with and the rod 25 pivoted direct to the arm 20. Both thread-eye arms may be attached to the spindle 41 to which the arm 46 is also fixed. The clutch 66 and the springs 77 may be replaced by a compression spring, in which case the arm 64 is dispensed with.
