Abstract
225,537. Mamet et Cie. Nov. 29, 1923, [Convention date]. Falling flap and other release indicators or annunciators.-In a time-alarm device a visual indicator 31, pivoted at 29, may, on the ringing of the bell 35, be lifted by a spring to the operative. position shown in Fig. 1. The pressing in of a tapered push member in the hole 27 depresses the indicator 31 to the inoperative position by acting cam-wise on the toe 32. Thereupon a catch, rigid with the indicator, is callght by the armature of the bell and thereafter held until the bell rings again.
