Trippensee Planetarium Company
Tellurian
Michigan: c. 1910
Maple arm, rectangular metal label
13.5 inches high; 21 inches long

A geared tellurian by Trippensee, with a terrestrial globe rotating at the end of a maple arm, and with a black-and-white painted wood representation of the moon revolving the earth, both revolving around a central brass sphere representing the sun, and with a black-and-white painted wood representation of Venus also revolving the sun. The entire assembly is mounted on a turned maple central standard, set on a round, stepped and weighted brass base, with an inset circular zodiac dial.  It has the maker’s label and a small, round compass inset on the arm.  When turned by hand by a metal post under the arm, the earth rotates, and the earth, moon and Venus revolve.  The three-inch terrestrial globe was manufactured by Rand McNally and copyrighted 1891; oceans are colored blue, the United States pink, Canada yellow, and Mexico green, with similar coloring throughout.

Description

The Trippensee Planetarium is a demonstration model of the movement of the earth, moon and Venus relative to each other and to the sun.  It shows such phenomena as the succession of seasons, and solar and lunar eclipses.  In addition to its educational objective, the tellurian is also decorative and entertaining. The original models, patented in 1908, have maple arms and central standards. Those produced around the second quarter of the 20th century have ebonized arms and central standards.  Models made after World War II models are of Bakelite or plastic.
