William J. Young Leveling Instrument with Goniometer

Description:

William J. Young Leveling Instrument with Goniometer, Philadelphia, Pennsylvania, lacquered brass instrument with a 14-in. scope above the horizontal enclosed silvered scale with dual apertures and verniers and adjustment knob below, north/south and east/west mounted spirit levels, engraved in script "W.J Young/Maker/Philadelphia" on the plate, ht. 9 in.

Note: This instrument differs from ordinary wye levels in that the height of one of the wyes is adjustable over a much greater range of heights than usually encountered, and in that there are provisions for measuring horizontal angles.

In the 1833 issue of the American Railroad Journal, Young introduces several new engineering instruments including one described as a "leveling instrument with goniometer." This lot is the only instrument ever found that satisfies Young's description, and it is believed to be one of the very few ever produced.
Estimate $800-1,200
