Filed: 1922-09-06
Abstract: 205,638. Smith, F. L., and Shackleton, G. W. Sept. 6, 1922. Stop motions, measuring.-In measuring stopmotions of the kind employing notched discs acting in conjunction with lever devices for indicating the length of cloth which has passed when a predetermined length has been woven, over the take-up roller and for stopping the loom the notched discs are driven by toothed gearing of the sun and planet type. As shown, notches w, w<1> in discs 12, 13, Figs. 3 and 4, driven from the shaft 4<a> of the take-up roller are adapted, when they are in register, to allow levers 14, 15 to fall, a projection 14<d> on the lever 14 thereby depressing a lever f mounted on the starting- handle of the loom. An arm of the lever f is thereby moved into the path of a part carried by the lay, and the starting-handle is moved to stop the loom. In order to prevent the lever 14 from falling before the notches are in register, it is normally supported by the engagement of the lever 15 with a projection 14<b> on the lever 14. The periphery of the disc 12 and the face of the disc 13 are provided with indication marks, which are used in conjunction with a fixed pointer to indicate the amount to be measured before the loom is stopped. To reset the device, the discs 12, 13 are moved out of engagement with their driving mechanism, and a projection 22<a> on an adjusting-pieces 22 is moved into engagement with the projection 15<a> at the same time as the required indication marks are opposite the fixed pointer, the adjusting-piece being then secured to the disc 13. To drive the discs 12, 13 a pinion 2 on the shaft 4<a> of the take-up roller gears with a wheel 3 which is loose on a sleeve 6, is secured to the disc 12, and carries a planet pinion 8 in gear with a wheel 10 on the sleeve 6. The sleeve 6 is loose on a fixed shaft 7 and carries the disc 13. The pinion 8 gears also with a fixed wheel 9 having one tooth less than the number of teeth on the wheel 10. The sleeve 6 is normally held in position on the shaft bv a forked lever 21. When it is desired to set the device, the lever 21 is raised, and the sleeve and parts mounted thereon are moved to the right of Fig. 3 to disconnect the pinion 8 from the wheel 9, thereby leaving the discs 12, 13 free to be rotated.
