Abstract: 19,459. Boult, A. J., [Leeson, J. R.]. Aug. 24. Winding - machines; driving - arrangements; stop-motions; stop apparatus, non-automatic; thread-guides.-The thread is automatically disengaged from the reciprocating thread-guide of a winding-machine when the cop driver is arrested, whether such arrest is due to manual operation, or to breakage or exhaustion of the thread, or to the cop attaining a predetermined diameter, by means of a pivoted bail 0 carried in lugs on a pivoted frame M which is weighted to press the thread-guide against the cop. The bail 0 is operated by a wire rod V, which is carried by the frame M and is provided with a bent end v, which is engaged by a curved slot u<2> in a lever U concentric with the axis about which the frame M moves, so that during normal working the rod V is not operated, but when the arm U is operated to stop the spindle it lifts the rod V and so tilts the bail O and removes the thread from the guide. The arm U is pivoted about a rod D and secured to a rod T, which carries a rod J operating the spindle clutch, a handle for manual operation, an arm W for automatic operation, and arms 6, 32 which effect the automatic operation when the thread breaks or fails and when the cop is the desired size. The arm W is provided with a shoulder w<2> which engages a corresponding shoulder w<3> on an arm W<1>, which, by means of a spring w<7>, tends to move in the direction of the arrow 2, Fig. 3, and when the shoulders w<2>, w<3> are disengaged, its lower end rides on the face w<10> of the arm W and so moves it and the rod T in the direction of the arrow 3, thereby effecting the disconnexion of the spindle clutch and the raising of the arm U. The shoulders are disconnected by the tilting of the rod T about the shaft D, which is effected by means of the handle on the rod T, by the engagement of the cop with an adjustable stop on the arm 32, or by means of the arm 6, which carries a bail 10, which, when an end breaks, is brought in the path of a toothed wheel 13 on the spindle. The bail 10 carries an arm 14 engaged by a slot 18 in a lever 17, which, when released, is operated by a spring 21 to raise the bail. Normally the lever 17 is held by the end of a stop lever comprising a rod 27 pivoted on the frame M and an adjustable resilient extension 29 engaged by the thread. The end of the stop lever engages a slot 20 in the lever 17 concentric with the axis about which the frame moves. The rod J for disconnecting the spindle clutch is carried by the rod T and is provided with a bevelled end j<1>, which engages with a flange g<5>, Fig. 4, on a sleeve, which is normally clutched to a driving-spindle B by a spring I and is splined to a spindle F, to which the cop tube is connected by means of a key f<3>. The spindle B is driven by a belt arranged to connect the spindle pulleys of all the heads or units to a common source of power. The frame M is adjustably 'weighted and is prevented from returning towards the cop by means of a lever S, which is secured to the frame and is provided with a shoe s, which engages a groove in a sector R. The threadguide is carried in a support secured to a pivoted holder n<4>, which is. reciprocated by a link from an oscillating arm.
