Description

ABSTRACT:
In a metronome, a toothed wheel and a bell drum each comprise toothings facing each other, by means of which the toothed wheel and the bell drum are in positive engagement with each other in defined angular positions. The toothed wheel and the bell drum are axially displaceable relative to each other on the toothed wheel shaft in order to release their positive engagement and to alter their angular position. When the metronome is in operation, the toothed wheel and the bell drum are kept in mutual positive engagement by releasable holding means.
