School Bell System
This website is dedicated to the School Bell System. From ancient times until now the Bell has been used to signal the start or the end of class lessons. The Chinese used their square clay gongs over 1000 years ago for this. The hand bell has been quite popular and low cost for the last 400 years. Then came the electric bell about 150 years ago. which was a revolution in convenience, giving the ability to operate many bells with one button press.
