Abstract: 22,645. McAuliffe, T. April 23, [date applied for under Patents Act, A.D. 1901]. Mules.-Relates to means for delaying, automatically or otherwise, the starting of the rollers at the beginning of the outward run, and for rotating the rollers during winding. The sliding part e' of the roller catch box drives the roller shaft d by reason of internal lugs e<3> on the clutch engaging with projections d<1> on the shaft. At the end of the outward run, as soon as the roller clutch has been disengaged, the part e' thereof is rotated backwards by a baud L, Fig. 3, and a loose and weighted wheel k'. The wheel k' carries stops k<3>, k<4>, of which the latter is adjustable, the rotation of the wheel in either direction being limited by reason of the engagement of one or other of these stops with an arm k<6> on the shaft k<1> uf the wheel. The rotation of the shaft is limited by the stops m<1>, m', the stop m' engaging with the underside of the bracket k, and the adjustable stop m<2> with the upper edge of a sliding, stepped plate 0, which is normally held in its extreme position shown in Fig. 3 by a spring. When the mule is spinning, the wheel k is rotated by the band L in the opposite direction to that indicated by the arrow in Fig. 3 until the adjustable stop k<4> thereon has engaged the arm k<6> and the stop m<1> has moved into engagement with the bracket k. The rotation of the wheel is then blocked, and the band L slips upon it. At the end of the outward run, as soon as the part e<2> of the clutch is free, the wheel k' rotates in the direction of the arrow, setting back the clutch, until the stop k<3> on the wheel moves the adjustable stop m<2> into engagement with the plate 0. The amount of this backward motion may be regulated by turning by hand the screwed stop m'. For regulating the amount of this backward motion according to the tension of the yarn, an arm j', Fig. 5, on the counterfaller shaft, is caused to support the weighted arm of a lever q, which is mounted on a suitable part of the carriage such as the faller shaft, and carries a pin or projection q', which, when the counterfaller rises too high, engages with a projection O<4> on the plate 0, moves the plate against the action of its spring, and allows the stop m' to fall on to one of the lower steps of the plate. At the beginning of the outward run, when the shaft k<1> is turned in the opposite direction, the spring plate 0 is released and is returned to its original position. The clutch e' is set back during the operation of backing- off, and in order to prevent it from being displaced relatively to the projections d' during the run-in, it is immediately clutched to the shaft by means of a friction clutch s, Fig. 7, so that the rollers can be rotated slowly during winding. During winding, the rollers are driven through the loose wheel p and the clutch p<3>, the levers of the two clutches p<3> and s being so connected together by spur gearing that the clutches are engaged and disengaged simultaneously. When the counterfaller rises very high and the plate 0 is moved against its spring to the fullest extent, an inclined surface O<5> on its guide rod engages near the end of the inward run with a lever, whereby the two clutches s and p<3> are disengaged.
