More Description

This book covers repair procedures for a selection of electric clocks spanning the last 100 years. The book is illustrated with 228 photos and drawings. Included are repair instructions for Telechron powered synchronous electric clocks, Seth Thomas electric striking and chiming clocks, other AC-powered electrics, and representative examples of ingeniously designed electromechanical clocks.Our story begins in the second decade of the 20th century, when Henry Warren invented synchronous clock motors that would run on alternating current (AC). These motors gradually gained acceptance and eventually dominated the domestic clock market.During the 1920's, battery powered electromechanical clocks were developed to compete with the emerging AC electric clocks. Electromechanical clocks freed their owners from weekly winding chores, and some were more accurate than the traditional spring driven household clocks. Inevitably, the electromechanical clocks became obsolete, as synchronous electric clocks gained wide acceptance.Through the 1930's and '40's, synchronous electric clocks continued to account for a large share of the domestic clock market. These clocks ranged from simple alarms and shelf timepieces, to chime clocks, and even floor clocks. It wasn't until the 1960's that traditional spring and weight driven clocks regained popularity, ending the reign of AC electric clocks. They remain collector's items that are worth maintaining and repairing.
