Campbell Tellurian

Stillman P. Campbell was an itinerant doctor who invented several quite unrelated devices. While living in Buffalo in 1867, he obtained a patent (#66,791) for a hand-cranked orrery in which the Earth with its moon moved in an elliptical orbit around a gas-jet Sun. The Tellurian Manufacturing Co. of Hartford obtained the rights for this patent and showed “the improved Campbell tellurian” at the American Institute fair of 1870. This tellurian was available in two sizes: 18 inches diameter with a 3-inch globe, and 36 inches diameter with a 6-inch globe.
This example is of the larger size. Its octagonal wooden box is marked “TELLURION / Patented July 16th 1867 / Dr. S. P. CAMPBELL”
