28,215. Savours, W. M. Dec. 3. Dials. - A device for use with a watch or other time - piece, for indicating the number of minutes remaining before a predetermined time has elapsed, consists of a graduated ring or disk adapted to be mounted so as to rotate relatively to the dial. The annular disk a, upon which are marked twelve divisions c numbered counterclockwise, each division being subdivided into five parts, is mounted upon a ring fitting loosely upon the periphery of the time-piece or upon a surrounding case. A disk of which the centre portion is transparent, so that the hands and dial-figures are visible, may be used. According to the Provisional Specification, the disk may be small enough to allow the hands and figures to be seen, and in this case is pivoted to the centre of the dial or glass. Reference has been directed by the Comptroller to Specification 6216/02.
