Abstract

156,697. FÚry, C. J. V. Jan. 8, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Electric clocks.-Relates to the type of clock where a pendulum a drives a wheel d by means of a finger c or an anchor o and is kept in action by an electromagnet k. The circuit is made and broken by the contacts of the teeth of the wheel either with a jumper f or with the anchor.
