Music box having time-sounding function

摘要

A music box having time-sounding function characterized in that a chime-zone with a row of chiming pins and a time-sounding zone with a row of time-sounding pins are formed on the periphery of a single rotatable drum in its rotating direction, said rows of pins successively fillipping vibrating teeth and thereby playing a chime, followed by time-sounding for a given hour. The number of hours to be struck is automatically selected by a sort of control cam installed parallel to said rotatable drum. The invented device, when coupled with a clock, can for instance chime and then strike once at "one o'clock" or strike two times at "two o'clock".
