Abstract: 6896. Leeson, J. R. March 30. Wire.-Relates to machines in which multiple strands of wire &c. are drawn from a number of rotary spindles or cops, and wound simultaneously and in a parallel fashion upon a core C on the spindle A'. Each delivery bobbin is carried by a split shell b, Fig. 5, which carries a brake pulley c and can be expanded, when the bobbin has been placed upon it, by a screwed plug E. Absorbent material saturated with lubricant is placed in a slot in the axle a. The receiving-spindle A' carries a core C, Fig. 3, to receive the strands and a fluted part s forming part of the stop mechanism of the machine. Each delivery bobbin is fitted with a drag plate h, which may be weighted and falls according to the decreasing diameter of the bobbin, thus varying the drag as the bobbin becomes empty. The strands are drawn from the delivery bobbins, passed under a pivoted tension wire x over guide-pulleys o, over pivoted spoons p forming part of a stop motion, and over a table 12 and tension felt y thereon to the traversing-guide by which they are wound on to the receiving-core. Each pulley o, Fig. 9. has its hub extended on one side and reduced on the other, so that the extended portion of the hub of one pulley will overlap the reduced portion of the hub of the next one, and, if a strand passes downwards between two pulleys, it will be caught by the extension o<1> of one of the pulleys and not get entangled with the axle. The spindle of the receiving-core is integral with the dri ving-shaft, which is driven through a clutch and carries a flywheel. The flywheel is connected with its shaft by a clutch, so that the wheel retards the sudden starting of the shaft, but offers no resistance to its stopping. When the shaft is stopped the wheel over-runs it, and is virtually loose thereon. A lug for releasing the driving-clutch, and a brake for engaging with a brake pulley on the driving - shaft, are carried by a spring shaft 19, which is provided with two handles 5, 17, of which the first is fast and the second is loose thereon. Both handles are provided with cam surfaces 15, 18. When the machine is to be started, the loose handle 17 is raised. The effect of this is to raise the lever 16, thereby operating the spring brake levers 10 of the delivery bobbins and removing the brakes from contact with their brake pulleys. The lever 27 is also raised by the spring 28, whereby the bell-crank levers t connected with the spoon levers p are raised out of the path of the corrugations s on the receiving-spindle. The handle 5, which is fast on the spring shaft, is now raised, the effect of which is to raise the lever 16 still higher, remove the brake from the driving-shaft, and place in gear the driving-clutch. This movement of the handle brings a hooked lever 24 into engagement with the hooked end of a lever E whereby the driving-mechanism is held in gear. The turning of the shaft 19 by the arm 5 also, by means of an arm 26 and pin 26<a>, depresses the spring lever 27, so that its pin 23 no longer supports the lever t, these levers and their corresponding spoon levers p being now supported only by the tension of the strands. Should one nf the strands break or fail, the corresponding spoon lever p rises, and its connected lever t falls, so that its end is caused to engage with the corrugated portion of the spindle, and the lever t, which is pivoted upon the lever E, is pushed away from the spindle so as to disengage the catches 21 and 22 on the levers 24 and E respectively and allow the spring shaft 19 to turn, thereby disengaging the driving-clutch and applying the brake to the driving-shaft and at the same time allowing the spring lever 16 to fall and the spring brakes to be applied to the delivery spindles When the reel of wire to be wound has attained a sufficient diameter, the machine is automatically stopped in a similar manner, by reason of the rocking guide-carrier R engaging directly with the lever E. The guide r may have a number of notches in its edge, so that only a s nall number of strands need be guided in each notch.
