Telechron, Inc., Ashland, Massachusetts, USA. Model Type A, serial no.
454, c. mid 1920's.
The red oak case was in very good condition and only needed a cleaning and waxing.
Control panel containing power knife switches for electrical motors. Setting and speed
adjustments for pendulum. The pendulum has a metal bar at its base and swings over a coil
located on the floor of the clock. The Rheostats control current to the coil and therefore
can slow the rate of the pendulum. In reality, the movement can be quite well regulated
using the bob adjustments and the small weights that can be added or subtracted from the
pendulum rod's weight pan.
