Ingraham “Adrian” Black Mantel Clock, 1899

This “Adrian” black mantel clock was made by The E. Ingraham Co., Bristol, Conn, U.S.A. The case is painted wood. The 8-day time and strike movement has the date code 11 99 (November 1899) stamped into the front plate. It strikes the hours on a thick coil gong (often called a cathedral gong), giving a rich, full sound. It strikes the half hours on a brass bell. These “black mantel” clocks were very popular in the United States around 1890 to 1910.

The 1899 Ingraham catalog shows this clock. My clockhistory website shows some more Ingraham catalogs.

Most clock movements have brass plates to contain the gears. This one has steel plates that are brass plated. The steel pivots rotate in holes drilled in the steel plates. This steel on steel action caused major wear to the pivots, and some wear to the holes. Several of the pivots were so badly worn that I replaced three gears (T3, T4 and T5 in the time train). I could have re-pivoted them, but had the spare gears handy in a parts movement.

Waterbury Clock Co. and Wm. Gilbert Clock Co. also used steel movement plates for a short time, but they were smart enough to install brass bushings for the pivots. Only Ingraham, to my knowledge, made mantel clock movements with pivots running in holes in the steel. Westclox made some alarm clocks during World War II (the Waralarm) with steel plates.

These Ingraham movements run very efficiently because of their deadbeat escapement. By contrast, the usual recoil escapement makes the escape wheel turn backward a little with each tick or “beat”.

Repair job 8691. Besides the three replacement gears mentioned above, I smoothed the clicks and made new rivets, polished the pivots, installed bushings, and adjusted the escapement (moved the verge up to equalize the drops). The old mainsprings were so filthy that I replaced them with 11/16 x .015 x 108″ springs (Merritt’s or Ronell Clock MS298). The old time spring was 3/4 x 0.0175″ and the old strike spring was 3/4 x 0.0172″.
