Filed: 1937-02-04
Abstract: 486,142. Induction relays ; actuation of switches. GENERAL ELECTRIC CO., Ltd., and COLLYER, J. E. Feb. 4, 1937, No. 3358. [Class 38 (v)] When current of a particular frequency superposed on power mains passes through a coil 24, a reed 21 is vibrated and moves a pawl 12 out of engagement with a ratchet wheel 5 connected to a permanently energized electric motor ; the motor then rotates and one or more cams 10 operate contact springs 11. In the form shown, there are two ratchet wheels 5 arranged one behind the other and each having its own pawl 12 which is tilted out of engagement with the wheel by its own vibrating reed striking a pin 20 on the pawl. The teeth on each ratchet wheel extend through 90‹ only and those on the rear wheel are arranged opposite to those on the front wheel. The rear reed is also responsive to a different frequency from that of the front reed. When the motor is released by the vibration of the front reed 21, the ratchet wheels 5 therefore rotate till the rear pawl engages the toothed portion of the rear wheel. A second rotation through 180‹ is obtained by sending a current of suitable frequency to set the rear reed in vibration. The motor may be of the induction type and a spring coupling may be arranged between the motor driven shaft and the ratchet wheels, causing a rapid motion of the latter immediately they are released. In modifications, there may be several ratchet wheels with co-operating pawls each released at a special frequency, or there may be one ratchet wheel only with teeth arranged at two diametrically opposed portions.

Patent GB-104692-A (GB)
Title: Improvements in Power Looms for the Manufacture of Oriental, Persian, Wound and other Knot-stitch Carpets.
IPC: D03D39/02
Filed: 1917-03-09
Abstract: 104,692. Soc. Renard freres. Nov. 12, 1913, [Convention date]. Stop-motions acting on derangement of pile-yarn supply. A loom for weaving knot-stitch carpets is stopped automatically if a stitch cannot be formed owing either to the absence of the pile thread at the distributing point or to the non-operation of the automatic locking of the stitch, a visible or audible signal being provided, if desired, to indicate the non-operative apparatus. If a pile thread 3, Fig. 1, is absent at the distributing point, the gravitational descent of a guided wire rod 4, raised by a lever 10 on a camactuated rock-shaft 8, is not prevented, and a bent projection 7 on the rod tilts a lever 14, which is pivoted at 13 and normally rests on a stop 16, so that the hooked end 15 of the lever engages and stops the spring-actuated return movement of a bell-crank 12, 11 on a cam-actuated rock-shaft 9, and a rod 42 attached to a lever at the end of the shaft 9 is not raised and acts to stop the loom through any mechanical or electrical device. The lowered end of the lever 14 may engage a ratchetwheel 18, which, together with an attached ratchet-wheel 19, Fig. 3, is loose on a shaft 17, rotated by a drive independent of that of the loom, but is normally rotated with the shaft by the frictional engagement of a spring 22, on an arm 21 fast to the shaft, with the ratchet-wheel 19. When rotation of the ratchet-wheels is stopped by the lever 14, the spring 22 produces on the wheel 19 a rattling noise to indicate the apparatus where the pile thread is missing, the stoppage of the wheels also constituting a visible signal. If the stitch is not locked, a small carriage 24, Fig. 4, sliding in the frame 23 remains, in the manner described in Specification 20983/10, [Class 142 (ii), Looms, Kinds &c.], in the position shown, and the end 27 of a rod 26 attached to the carriage is not raised out of a slot 34, Fig. 7, in a sliding bar 29 actuated by a cam and spring, so that the spring-actuated movement of the bar 20 is stopped by the contact of the end 27 with the end of the slot 34, and the full return movement of a rod 41 is prevented and the loom is stopped, the rod 41 being connected to the bar 29 by an arm 38 and a stirrup 36 engaged by a guide-slot 35 on a plate 39 secured to the bar 29. The length of the slot 35 and the breadth of the stirrup 36 at right-angles to the plane of the slot are such that the parts are in engagement whatever be the position of the knotting-apparatus. When stoppage occurs, the end 27 may act upon a pivoted arm 30 to turn it to project at rightangles to the bar 29 and thus give a visible indication of the apparatus where the locking has not been effected. The visible or audible signal may be operated electrically by an electric contact dependent on the movement of the rod 4 or the carriage.
