Abstract

518,667. Information indicators. McCONACHIE, R. G. July 28, 1938, No. 22410. [Class 118 (i)] [Also in Group XVII] A manually-set indicator of inaccuracy of a timepiece consists of a combination of two relatively movable members one marked in units of time and the other having an aperture for adjusting to register with one of the markings. An apertured disc d, Fig. 1, may read over a scale a on the disc pivoted below it, or a money box j, Fig. 3, may have a hole m to read on a scale of numbers on a rotatable upper part l and a disc n marked F and S so that a knob with a mark p may be set to indicate "fast " or "slow." Where scales reading right and left from zero are used, fast and slow may be distinguished by different colours.
