As part of a larger effort to rehabilitate the roof and cupola of Congress Hall, Kreilick Conservation, LLC was retained by RAAD Construction Group, LLC in 2016 to restore the weather vane and time ball for this historic structure. Congress Hall, located at the corner of 6th and Chestnut Streets, was designed by Samuel Lewis and completed in 1789. It is in a National Historic Landmark District (1956) and is listed on the State and National Register of Historic Places (1966).

The weather vane, time ball, and finial were disassembled and transported to Kreilick Conservation’s conservation studio for treatment. The weather vane is 82.5” long and 22” top to bottom at the spindle. The finial is 29” tall, and the time ball is 20.5” in diameter. The frame of the weather vane is iron, the infill panel is sheet copper, the bearing rings are brass, and the directional arrow points have lead counter weights attached with copper straps. The finial is sheet copper. The time ball is sheet copper reinforced with brass at the top and bottom. The weather vane, time ball, and finial were repaired and re-gilded following the removal of deteriorated earlier gilding. The original spindle, which had been severely corroded, was replaced (by others). Once restored, the weather vane, time ball, and finial were returned to the site and reinstalled on the new spindle.
