Abstract

18,007. Villethiou, A.-J. M. de. Aug. 12, 1911, [Convention date]. Dials.-Relates to clocks of the kind having a rectangular dial with scales for the hours, minutes, &c., each consisting of parallel graduations, hands or indicators attached to endless bands being caused to traverse the diaL According to the invention, the hands travel downwards in front of their respective scales. For each scale there is a series of hands such as e, each set of hands being mounted on an endless band b, passing over pulleys a, a<1> driven continuously by the clock through belts and pulleys or other suitable gearing. The hands are at a distance from each other equal to the length of the scale, and each hand passes away from the dial after having traversed the scale. In the hour scale, the XII division-mark is preferably placed in the centre. The scales for the hours, minutes, &c. may be superposed.
