Title: Method of and apparatus for preventing lateral contraction of fabric during the process of weaving
IPC: D03D41/00
Filed: 1920-11-27
Abstract: 154,593. Boyer, F. Nov. 29, 1919, [Convention date]. Beat-up motions; reeds; lays; shuttleraces; shuttles shuttle boxes; picking-motions; weft, deflecting for slackcning. - To prevent lateral contraction of the fabric during weaving, the weft thread is caused to assume a serpentine line on the ground of the shed before the beat-up, so that there is no tractive force on the warp or weft threads at the beatup. The weft thread is inserted by means of a shuttle 19, Figs. 5 and 11, which is thrust through the shed by means of a spindle or bar 48 operated by a tappet 62 on a chain 61 driven from a shaft 69 by gearing described. The shuttle has a " wedge-shaped " groove 49 engaged by a corresponding " wedge " on the bar 48, and is furnished with bearings 20, 21 carrying connected screws 22, 23 having points 29 provided with hollow spaces 31, whereby one of these screws can be connected to a spring-controlled catch on a rod 38, which is caused to reciprocate and also to rotate. The screws are thus moved across the shed and rotated, the rear screw causing the weft thread which issues from a removable spool-box 24 in the shuttle and is guided by guides 26, 27, 28 to the fell, to assume a serpentine form. After passing through the shed, the shuttle engages a thrust-bar and rotating rod at the opposite side of the machine, and is held fast by devices at that side, whilst the bar 48 and rod 38 move back across the shed, the spring-controlled catch on the rod 38 disengaging itself from the screw. The lay 2, mounted between holders 17, 18 on beater arms 16, then descends to beat up the weft, rollers on bolts 15 on the arms sliding in channels in fixed guides 13. When in its position of rest, the shuttle engages slots 76 in fixed guides 11. The shuttle is provided with warp-guiding bars, and after the change of shed, is thrust through the shed by the devices on the opposite side of the loom to that shown. In a modification, the screws are replaced by toothed wheels 78, Fig. 13, which are caused to rotate, when the shuttle is thrust through the shed, by engagement with a toothed rack-like weft-carrier 88 mounted on a " rule " 87 on rocking levers 84, which are rotated to withdraw the carrier 88 at the beat-up. The wheels 78 lie in slots in the shuttle points, which are connected by warp-guiding bars 89, 90.

[Also in Groups XL (a) and XL (c)] Frequency variations of the input drive to the buncher B of a velocity-modulated amplifying or oscillator tube are detected by a discriminator FD and its output used to vary the operating condition of the tube, e.g. its energizing potential, so that the position of optimum bunching along the drift stream is kept constant for maximum efficiency of power extraction at the catcher C over a wider bandwidth. f.s.v. This requires - to be a constant, where f is V 0 <SP>3</SP>/ 2  the frequency, s the drift length, v the voltage applied across the buncher gap and V o  the electrode gun accelerating voltage, or since i o #V o <SP>3</SP>/ 2 , where i o  is the beam current then f/i 0  must be constant if s is to be constant, and v is constant. The discriminator output V 1  and a voltage V 2  derived across the cathode resistor R proportional to the cathode current i o  are therefore compared in a comparator circuit and the difference (V 1 -V 2 ) applied to vary the H.T. energizing voltage of the tube so that f V 1  = V 2 , and - is kept constant as the input io frequency varies. The input may be a frequency, amplitude or pulse modulated signals In a modification the discriminator output controls the attenuation of the drive of amplitude V applied to the buncher B so that fv and hence the distance s of the position of optimum bunching are again kept constant if V o  is constant. The tube may be a klystron or of travelling-wave type.
