Abstract: 21,358. Ramsden, J., Taylor, A. T., and Ramsden, J. Oct. 11. Mules.-The quadrant chain 10 is passed round one or more pulleys 9<a> on the quadrant nut and round a corresponding number of loose pulleys on a fixed stud 13 before being attached to the quadrant nut, so that a much smaller movement of the quadrant is necessary during winding-on. The faller leg is in two parts 19, 19<a>, of which the first telescopes into the second and is connected with it by a screw and nut arrangement 29, 28, operated by means of a ratchet 30 and fixed stud, so that at each runin of the carriage the faller leg is shortened and the faller raised a sufficient amount for winding-on during the next run-in. The screw employed is of variable pitch, and this part of the invention may be applied to ordinary faller legs. The copping-rail 35 is made of the section shown, having one face 35<a> made plain and used for making cross-wound cops, while the other face 35<b> is made of the ordinary form and is used when it is desired to wind cops in the ordinary manner. The rail is supported throughout its length in a channelled rail 37, and may be reversed therein so as to bring either of the surfaces 35<a> or 35<b> into action as desired. For making cross-wound cops, the foot of the faller leg is supported upon a frame or rocker 38, which is raised and lowered as the carriage runs in by means of an internal eccentric 43, the axle 44 of which is rotated in one direction as the carriage runs in, and in the opposite direction during the outward traverse by means of a pair of cords 48, 49, of which each has one end attached to a drum on the axle 44 and the other to a fixed point on the headstock. In order to automatically place this cross-winding mechanism out of action for the last few coils of yarn, the cord 48 is secured to a spring rod 50 for taking up slack in the cord, and the cord 49 is secured to a stud 52 on the end of the lever 53. This stud is provided with a ratchet arrangement whereby the length of the cord may be adjusted, and with a catch lever 61, which engages, when in the position shown in full lines, behind a projection 65 on the frame. As the carriage approaches the beam during the run-in, the catch 61 is lifted by a chain 66 attached to the quadrant 2<a>, whereby the cord 49 is slackened, the eccentric 43 ceases to be rotated, and the slack in the cord 48 is taken up by the spring rod 50. The parts are so arranged that the eccentric is stopped with its smallest radius uppermost, so that the faller is in its highest position and the last coils are wound about the cop nose. During the outward run, the quadrant 2<a> engages with a quadrant 62 on the lever 53, and forces the catch 61 again behind the projection 65. During the outward run, the faller shafts 22, 25 are locked together by reason of levers 70, 71 thereon being connected by a spring pin, which is connected by a chain 56, passing over the pulleys shown, to a scroll on the tin-roller shaft, which is rotated in the ordinary manner for lifting the faller leg into its operating position and into engagement with the stud or bowl 60 on the rocker 38. To prevent the too sudden upward movement of the counterfaller when the levers on the faller shafts are unlocked, the fallers are connected together by a chain passing over a pulley, so that the counterfaller can only rise as the winding-faller is depressed.
