Book 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.

Book Description
Book 6 Seth Thomas covers the most popular movements produced by this well-known American clockmaking dynasty. Seth Thomas clocks rank high among repairers for quality and durability. Collectors are often attracted to Seth Thomas clocks for the same reasons, and this manufacturer's name is more recognizable to the general public than any other.Seth Thomas (1785-1859) started work in the clock manufacturing business in the early 1800's. The company is best known for the clocks made during the American mass production era, extending from the late 1800's until the early 1950's.Chapter 1 is devoted to the No. 89 strike movement, which is one of Seth Thomas' most plentiful movements. Chapter 2 covers the main chime movements made by the company. These are the No. 113, the No. 124, and the Sonora Chime. Chapter 3 contains material on the early, difficult-to-repair ship's bell movement. Chapter 4 features a variety of movements which strike the hours only, or the hours and half hours. These made up the largest share of Seth Thomas production. Chapter 5 includes material on simple, early alarms attached to movements. There are also articles on the Long Alarm and the Automatic Eight-Day Alarm. Chapter 6 covers several timepieces, that is, mechanisms which do not strike or chime.The material in the book is based on features from the editor's Clockmakers Newsletter, a monthly clock repair publication produced from 1987-2008.
