Abstract

1409572 Escapements X THEURILLAT 4 Dec 1972 [6 Dec 1971 3 25 Jan 1972 29 May 1972] 55920/72 Heading G3T In an anchor escapement the gaps between teeth 2 of the escape wheel 1 are irregular so that the wheel jumps every second, this jump being made visible by an indicator driven by the wheel. The indicator may comprise a pointer, which may carry a member of a colour which contrasts with fixed zones of a different colour Figs. 3, 4 (not shown). Alternatively, coloured segments may become visible through moving apertures.
