Abstract: 230,368. Golland, H. S. Sept. 13, 1924. Mules.-In means for cross winding yarn in spinning mules, as described in Specifications 1470/14, 184,386, and 195,018, the duplicate ratchet and pawl mechanism described in Specification 1470/14, for rotating the cam which vibrates the guide wire fingers is replaced by a ratchet h and pawl g<2> carried by the cam g, in combination with a disc i having a cam part i<1>. The fixed bracket b formed with a toothed quadrant b<1> is loose on the winding-faller shaft a, while fixed to the latter is a toothed quadrant c engaging with a toothed quadrant c<1>, which latter is loosely pivoted at c<2> on the bracket b and is adapted to rotate a bracket d loose on the shaft a through a pin- and-slot connection c<3>, d<1>. The bracket cl carries a loose shaft e fixed to which are the ratchet wheel h and a pinion f gearing with the toothed quadrant b<1>, while loosely mounted thereon is the cam-plate g having the slot g<1>, as described in Specification 195,018. The disc i and a pinion i<2> fixed thereto are mounted loosely on a stud j secured to the bracket d, the pinion i<2> gearing with a pinion k fixed on the shaft e, while each set of mechanism as described is provided with a finger m formed in one with, or connected to, the sickle m<1> which carries the guide wire n. The finger m carries a bowl m<2> disposed in the slot g<1> of the cam g, which latter also carries a bowl g<3> contacting with the periphery of the disc i; on commencing, to wind a set of cops the bowl m<2> occupies the upper end of the slot g<1>, and the bowl g<3> the mid-position of the portion i<1>. When the winding-faller shaft a is oscillated the bracket d is rocked through the action of the quadrants c, c<1> and pin-andslot c<3>, d<1>, the shaft e is rocked on its axis, and the cam g is oscillated with the bracket d and is rocked on the shaft e through the pawl g<2> and ratchet wheel h. When the guide wire n is raised the bowl g<3> is withdrawn from the disc i, but when the wire n is lowered the bowl g<3> contacts therewith and ensures that the yarn is directed to the proper position on the shoulder of the chase. To effect the building of the cops the shaft a is also slowly rotated in the direction of the arrow, Fig. 1, thus imparting through the quadrants b<1>, c, c<1>, the bracket d, and the pinion f a rotation to the ratchet wheel h, which through the pawl g<2> rotates the cam g to increase the lift and lengthen the chase to its full value; the shaft c also rotates the disc i through the pinions k, i<2> to raise the wire n on each return movement. The wheel h carries a pin o to contact with the plate g and ensure contact between the bowl g<3> and the part i<1> while the cop bottom is being formed. When backing-off, the tail of the pawl g<2> contacts with a ledge p on the bracket d and is held away from the wheel h, the ledge p also serving to keep the pawl g<2> off the wheel h when the cop bottom and chase have been formed, the disc i then continuing to rotate and always presenting its circular periphery to the bowl g<3>.
