Early Warren Clock Company Auxiliary Clock

This clock has an “auxiliary” type movement which keeps the clock approximately on the correct time if the electricity fails.

Auxiliary movement showing winding key and type A motor

Showing the “auxiliary” type movement. When the electricity fails, the windup movement between the brass plates starts ticking and the clock stays approximately on time. The vertical rod on the left is the pendulum. During normal operation, the pendulum is attracted to the armature and cannot oscillate. When the electric power fails, the pendulum starts swinging. The key at the lower right of the brass movement is used to wind the mainspring. This clock has the "type A" synchronous motor, made from 1916 to about 1920. This was Warren’s first production clock motor.

Nameplate serial number 2165 for type A motor.

Motor nameplate. Serial number 2165. No patent dates!

Label inside the back door. No patent dates, just "Patents Pending"

Comments on above clock

Since it does not have the name "Telechron" on the dial it must have been made in December 1919 or earlier.

Since it has no motor patents, just "Patent Pending" it must have been made about November 1918 or earlier. If it were later, the name plate would have the October 29, 1918 patent on it.

Auxiliary Wall Clock, 12" dial and 16" case

This is a transition clock in that the dial says “Warren Clock Co.”, while the motor nameplate says “Warren Telechron Co.” Thus the clock dates to around 1926, the year the company's name was changed. Courtesy Richard C. Tjarks.
