CLOCKS AND OTHERS

 


 

 

These are "slave" clocks; they are so-called as they don't have motors but instead coils that respond each minute when a pulse is sent to the clock by a centrally located master clock. These were very common in schools, banks, hospitals, and other public buildings as they all are synchronized by one master clock. The examples seen here came from schools. The square wood model is the oldest.
