Title: Improvements relating to frequency regulators for alternatingcurrent circuits
IPC: G04C15/00
Filed: 1922-04-04
Abstract: 193,732. Le Tall, F. W., (Westinghouse Electric & Manufacturing Co.). April 4, 1922. Electric clocks.-In a system for regulating the frequency of the current in an alternating-current circuit supplying power for driving a clock, a synchronous motor 27 energized from the circuit supplies power through a differential device to a train of wheels governed by a master escapement or standard frequency device. In the arrangement shown, the generator 12 which supplies the current, the frequency of which is to be kept constant, is driven by a direct-current motor 11. A resistance 17 in the field circuit of the motor is regulated by means of a pilot motor 22 driven in a.ccordance with the operation of the differential mechanism. The synchronous motor 27 is geared to shafts 32, 37, Fig. 6, the former of which drives a clock 28 by means of a pin 45 and crank arm 46. The shaft 37 carries an arm 51 which drives a pin 52 carried by a shaft 53, which is capable of axial displacement in its bearings. A worm 54 on the shaft 53 drives a worm-wheel 57 mounted on a hollow sleeve 58, Fig. 4, which surrounds a shaft 61 carrying a wheel 59. This wheel is a part of the train of wheels constituting the master escapement, and is yieldably connected to the wormwheel 57 by a spring 64. The end of the shaft 53 engages one arm of a bell-crank lever 65, pivoted at 66, the other arm of which carries a contact 67 mounted between contacts 68, 69. The pressure between the lever 65 and the shaft 53 may be regulated by means of adjustable weights 77, 80, Fig. 2, and by means of an,adjustable spiral spring secured to the pivot of the lever. The master escapement is thus driven by the synchronous motor through the worm 54, wheel 57, and spring 64, and any variation in the speed of the motor causes a torsional movement in the spring which effects a displacement of the shaft 53, and thereby causes the contact 67 to engage one or other of the contacts 68, 69. The pilot motor 22 is thus energized and moves a contact-member 18 over the resistance 17 in order to produce the necessary correction in the field strength of the motor 11. In order to prevent over-travel of the contact-member 18, the latter carries a roller 81, Fig. 2, which engages the inclined edge of a bar 82 adjustably secured to a pivoted support 83 which also carries the contacts 68, 69. As the roller traverses the bar, the support is raised or lowered, thereby producing a premature separation of the contactmembers 67, 68 or 67, 69 in order to prevent hunting, the inertia of the moving parts completing the, regulation.
