Seth Thomas Clock Company made many Westminster Chime clocks in the 20th century. Here is a beauty in a tambour case called the “Wickford”, made around 1930. The dial is engraved and silvered brass with applied numerals. The motor is the Sangamo self-starting synchronous motor, a very reliable motor made through the late-1940s.
The case is 20 13/16 inches wide and 10 inches tall. The dial’s minute track is 5 1/2 inches diameter, and the minute hand is 2 13/16 inches from center to tip.
The motor runs the hands, and winds the strike and chime mainsprings. Slip-clutch (brace) ends on the 2 mainsprings prevent over-winding. The movement is nicely nickel plated.
Repair job 6441. A previous repairer made file marks on the front plate when installing bushings. I polished the pivots and installed 21 bushings. I adjusted the chime mainspring to slip after 7 1/2 turns of winding, and the strike mainspring to slip at 7 turns. I installed new cloth-covered electric cord and a new plug at the end that plugs into the clock.
