A splendid c 1908 Trippensee Tellurium ( Orrery) As a refined scientific instrument, this tellurium allowed to introduce eager student to the basics of our Universe by reproducing the motions of the solar system. Such devices had become popular during the 17th century, following the publishing of Sir Isaac Newton’s universal theory of gravity in 1687. In 1905, three brothers by the name of Trippensee purchased Laing and re-named it the Trippensee Manufacturing Co., located in Detroit, Michigan. Their first products were marketed as Laing Planetariums, however an improved model was soon introduced bearing their own name. It substituted the previous cord driven gears with a more reliable bicycle-style chain and gear drive. Such model is being offered here. It is in perfect working condition, all planetary, gears and chains are original, present and functional. Quite amazing for a scientific instrument that’s well over 100 years old. The terrestrial globe itself is made by Rand McNally. It identifies Empires of the past, including Austro Hungarian, Ottoman and Russian Empire. A copyright of 1891 is also shown though since Trippensee did not manufacture Telluria before 1905, we believe this model to be c 1908-9 The entire model has much less than expected wear and a beautiful patina. Most extensive wear to be noted is loss of the black finish on the arm of the instrument. Minor rubbing and soiling on the terrestrial orb. No rust to the chain or gears, no dents to the brass sun. Venus and the moon are also in good condition. Overall a very well preserved piece. $2999 - #dv111 - SOLD
