Abstract
24,939. W³sthoff, E., and Krimnitz, M. Nov. 11. Alarms.-In an alarm clock in which the alarm is sounded not continuously but at fixed intervals, and which embodies the known device of a four-toothed star-wheel on the minute - arbor, whereby a spring-pressed detent is raised and the alarm scape-wheel freed, means are provided for setting the hands without releasing the alarm. For this purpose, there is a pawl i on the end of the arm b, which raises the arm when a tooth of the star-wheel h presses upwardly against it, but is merely pushed aside without moving the alarm detent b when the wheel h is moved in the reverse direction.
