Ansonia “Seneca” Oak Cabinet Mantel Clock

I did minor adjustments to this clock back in 2011, see Ansonia “Seneca” Oak Cabinet Clock.

The Ansonia “Seneca” mantel clock has an oak case 15 3/4 inches tall and 11 3/4 inches wide, and the minute hand is 2 1/8 inches long. It’s an 8-day clock that strikes the hour and half-hour on a cathedral (heavy wire) gong. It was made around 1894.

The customer convinced me to do a “partial overhaul” to save money. This meant to take it apart, clean the movement parts, and repair just the worst wear. The movement appeared to be in good condition, but didn’t run well (even after lubrication), so I agreed to this, with the understanding that if I found bad wear after cleaning, I would talk to the customer and get approval to do more work. It turned out to be not too bad (see below).

Repair job 8933, partial overhaul. I disassembled and cleaned the movement, filed and burnished 14 pivots, and installed 5 bushings. The movement has nice, original, thin mainsprings that have caused only 10% wear to the mainwheel teeth. Both mainsprings are 3/4 inch wide and 0.0155 inch thick. I lubricated the first three pivots of each train with 10W-60 synthetic motor oil, and pivots 4 and 5 with 5W-40 synthetic oil.

Before the repair, the pendulum took a very sluggish motion. After repair, the swing was excellent!
