Pipe Organ. Culture: American. Dimensions: 16 ft. 1 in. × 9 ft. 3 in. × 9 ft. (490.2 × 281.9 × 274.3 cm). Maker: Thomas Appleton (American, 1785-1872). Date: 1830.This organ is the oldest and finest extant product of the renowned Boston craftsman Thomas Appleton (1785-1872). Built in 1830, probably for South Church in Hartford, Connecticut, it was reinstalled by Emmons Howard in 1883 at Sacred Heart Church in Plains, Pennsylvania, where it was discovered unused and neglected in 1980. The organ's conservative tonal design and mahogany Greek Revival case reflect British models of the late 18th century. Standing over 15 feet tall, with gold-leafed façade pipes (diapasons), the organ comprises 16 ranks totaling 836 pipes, two 58-note manuals, and a 27-note pedalboard added when it was reinstalled (1883). Wind is supplied by hand- pumped bellows. The pipes of the upper manual are mainly enclosed in an elevated box with louvers that can be opened by means of a pedal for dynamic expression.
