Stackpole & Brother Transit

<< >>
This transit is marked "Stackpole & Brother New York 655." The Museum has the original bill of sale showing that John Ferris, a surveyor of Dutchess County, N. Y., bought it from the Stackpoles in 1866. The basic instrument cost $250, while the meridian finder-marked "Stackpole's Mern. Findr. Patented, Sep. 26, 1865 107"-cost an additional $40. William Stackpole's patent (#50,182) describes a small reflector that attaches to the objective end of the telescope, and that enables a surveyor to easily use the sun to locate the true meridian.
