Early parlor Kaleidoscope manufactured by Charles G. Bush, Providence, Rhode Island. Circa 1873. Size: 13.5 inches height x 10 inches length x 6 inches base diameter. Excellent original condition and fully operational. Charles Bush is credited with the design for the first parlor kaleidoscope in America and was granted two patents in 1873 and 1874. He manufactured these instruments in Providence, RI and Claremont, NH. This example has a black pebble finished hardboard barrel with a spoked brass wheel rotating an object cell, filled with pieces of solid and liquid filled glass. The barrel is supported on a turned wood stand. Bush developed the first liquid filled ampules which allow the kaleidoscopic designs to continue to move even after the rotating wheel has come to rest. It is rare to find a Bush scope in such good condition.
