Abstract: 322,339. Kershaw, G. Dec. 1, 1928. Delivery, stopping.-In unwinding yarns or threads from bobbins or other packages, e.g. in a creel, holding devices are provided which come into operation on stoppage of the machine which is drawing the yarn off the bobbins and engage the portions already drawn off to prevent the weight thereof or the tension therein from unwinding further portions. The holding devices are applied in conjunction with the yarn guiding or deflecting devices, being actuated to hold the yarns on stoppage of the unwinding machine and to release the yarns when the machine is restarted. In unwinding from bobbins b, Fig. 1, each yarn m or group of yarns passes over a twoarmed bracket f, Figs. 2, 3 and 4, secured to a vertical shaft c which, in starting and stopping, is turnable about its vertical axis by a connecting-rod d acting through arms e. The brackets f comprise arms f<1>, f<2>, the former inclined downwardly, the latter provided with a guide-eye l while a disc k is adapted to revolve about a peg j which projects upwardly from a surface i. Normally the yarn m passes through the guide-eye l above and clear of the arm f<1> and clear of the members i, k, Fig. 3. When the machine is stopped the bracket f is turned and the yarn held between the disc k and the surface i, Fig. 4. In a modification, the disc k and surface i are replaced by a ball n engaging a seating o, Fig. 5. In a further modification, the disc k is replaced by a brush and the yarn secured by the tips of the bristles against the surface i, while in another form, on stoppage of the machine the yarn is caused to follow a zig-zag path at the guide-eye l, Fig. 13, and is held beneath an annular tension weight v freely mounted on the shaft c. In a still further modification, a vertically-extending bar w, Figs. 15 and 16, formed with guide-eyes x is made to swivel about its longitudinal centre-line, the bracket y carrying the tension weight z being formed with a retaining-lip y<3>; while alternative forms of another arrangement are shown in Figs. 18 and 20, the member 5, 6, 7, Fig. 18, being turnable about its vertical axis, the yarn normally passing clear between the bars 5, 7, and the guide-bar 8, Fig. 20, being similarly turnable.
