Abstract: 461,085. Actuation of switches. GENERAL ELECTRIC CO., Ltd., and KEELEY, F. J. Aug. 21, 1935, No. 23470. [Class 38 (v)] [Also in Group XXVI] A power-driven operating mechanism for electric switches comprises an electric motor 5 coupled to a screw-threaded shaft 2 on which is threaded a fly-wheel 1 connected through a bushing 18 to a toggle linkage 16, 17 acting through rods 25 on a switch operating member 26. The shaft 2 is provided with a spring- controlled brake 13 having a pull-off magnet 7 which is connected in parallel with the motor 5. Starting from the position shown, if the motor 5 and coil 7 are energized, the shaft 2 rotates and the fly-wheel 1 due to its inertia moves along the screw-thread to the right until spring catches 11 engage shoulders 12 on the shaft 2. The fly-wheel then rotates with the shaft and when a sufficient speed is reached the catches 11 are disengaged by centrifugal action. If now power is cut off, the brake 13 stops the shaft 2 and the fly-wheel moves to the left due to overrunning and moves the toggle links 16, 17 to close the switch. If power is cut off before a sufficient speed is attached, the catches 11 prevent movement of the fly-wheel 1.

Abstract: 317,322. Hydrometer Akt.-Ges., (Assignees of Central-Wechselstuben Akt.-Ges.). Aug. 13, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Roller-and-sheet recording-apparatus.-Relates to a time recording device for measuring instruments in which the time indications are recorded on a recording strip. In the casing 1 of a measuring instrument is arranged clockwork driving a wheel 2, with two pins 3, which makes one revolution every two minutes. An arm 5, mounted on the recording rod 4 and constantly pressed by the spring 6 against the stop 7 is deflected each minute by the pins 3, at the same time giving the rod 4 a small oscillation. At the top of the rod 4 is provided a pin 8 and an arm 9 carrying a pencil 12, which is prevented from turning by a small guide 10. In the hub of the arm 9 there is provided an oblique slot 11 so that when the rod 4 makes an oscillation, the arm 9 is slightly raised and brought back again to its initial position, thus providing a short stroke d<3> every minute on the time line d on the recording strip a. A cam wheel 13 has three identical arms 13‹, and a slightly higher cam 13' on which slides with its tooth 14‹ an arm 14 rotatable about the pin 15, which raises accordingly by means of a collar 16 the rod 4 in opposition to the action of a spring 17. The cam wheel 13 is connected to the minute wheel 18 which carries the minute hand 19, which can be set to exact time by means of the handle 20 and setting rod 21. The pencil 12 thus draws on the time line d a short stroke d<3> at the end of every minute, a short vertical line d‹ at the end of every quarter of an hour, and a longer vertical line d<1> at the end of every hour.
