This clock has an "auxiliary"
movement which keeps it approximately on time if the electricity fails.
11 inch square walnut
case 4 1/8 inches deep. The paper dial has a 6 1/2 inch time track
The dial does not
have the Telechron trademark
The auxiliary 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.

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.
