Ansonia Enameled Iron Black Mantel Clock

June 6, 2013 | By | 1 Reply More

This heavy Ansonia mantel clock has a cast iron case with a glossy black enamel finish. The case is 10 1/4 inches tall and 16 1/8 inches wide at the feet. The paper dial has a 4 13/16 inch minute track, and the minute hand is 2 1/8 inches long.

The movement is Ansonia’s 4 pillar 8-day time and strike movement with thin mainsprings. The time mainspring was an old replacement that was too thick. I replaced it with a Merritt’s Antiques P-1496 mainspring in the red, yellow and orange package. The spring’s dimensions are 3/4 inch wide, 0.0142 inch thick, and 96 inches long. The original strike mainspring is 3/4 inch wide by 0.0145 inch thick.

The strong time mainspring caused wear on the mainwheel teeth. This Ansonia movement uses thin mainsprings, about 0.0145 inch thick. DON’T use thicker springs in these clocks!

Movement repair

I polished the pivots and installed 14 bushings. I smoothed the pallets, closed the verge for proper drop, and tightened the click rivets. (And installed the proper time mainspring, as discussed above.)

Repair job 6006.

    Hello, I have this exact same clock but one of the feet is missing. I was wondering if you know where I can get a replacement or have one cast from the ones I have?
