Abstract: 10,813. Wade, H., [Leeson, J. R.]. May 1. Winding-machines; stop-motions; stop-apparatus, non-automatic.-In drum winding-machines, the spindle F is carried by arms g which are suspended from a point vertically above the driving-drum upon a carriage H which can slide vertically upon a rod h, so that as the yarn package increases in diameter, the spindle rises vertically, and when it is moved out of contact with the driving-drum, its movement is approximately ho izontal. In moving outwards, a part of the spindle or of an extension thereof is brought against a fixed brake J also mounted on the carriage H. The axle of the swinging arms g is operated in one direction by a starting and stopping handle K, and in the other direction by a spring g<5> acting on the end of an arm g<4> carrying a hanging rod U, which, for the purpose of holding the spind e in the winding position, may be locked to a second vertical rod V suspended from the carriage H. The rod V moves on fixed guides, the rod U is forced towards it by means of a spring pin u<1>, and the two are normally locked together by a latch u<5>, v<3>, of whih the part v<3> is provided with the inclines v<5>, v<7>. The yarn passes to the traversing thread-guide e through the tension device Q and through the eye r of a tilting drop wire R, the tail r<5> of which engages with a bail R<3> connected by adjustable levers s, s<1> and a connecting-link t with a swinging pawl lever T, which hangs from a lever T' and has its movement in one direction limited by a pin t<4>, a second arm t<7> of the lever T<1> engaging with the side of the rod U. On depressing the lever K for starting the winding, the yarn is liable to be insufficiently taut, and the engagement of the upper part of the latch u<5> with the incline v<7> slightly separates the rods U, V. This has the effect of preventing the pawl lever T from improperly engaging with its ratchet-wheel t<3> on the cam - shaft. When the yarn breaks or becomes too slack, the pawl T engages with the rotating ratchet-wheel, and the lever T disengages the rods U, V from one another, whereupon the rod U is depressed by the spring g<5>, causing the spindle - carrying arms to be turned, the yarn package to be removed from its driving-drum, and a brake surface on the spindle to be pressed against the brake J. Simultaneously with the downward movement of the rod U, it is swung slightly to the left by means of the bevelled portion v<5> of the latch v<3>, and thereby caused to engage the adjustable screw m<6> of a tilting thread-lifter plate M, the edge of which normally rests upon the thread-guide ; but, when tilted by the rod U, the plate M raises the thread out of the notch e of the guide, so that the thread no longer participates in its movement. As the package increases in diameter, the carriage H and rods U, V rise until a catch lever V<2> on the rod V engages with an adjustable bent rod Z, by which it is turned so as to cause a cam-surface v<9> on the catch lever to engage with the edge of a plate U<2> on the rod U and so separate the rods U, V, when the spindle is swung aside and stopped as before. In order to prevent the yarn package, as it rises during the winding operation, from rebounding on to the surface of the drum, a spring dog lever W is provided which allows an upward movement of the rod V but prevents its downward movement until the lever is operated against the action of its spring W<5> by means of the extension W<4>. The machine is shown provided with an oscillating frame L, such as that described in Specification 4906/14, for the purpose of interrupting the consonance of movement between the threadguide and the winding-spindle.
