Title A name given to the resource Willis Pendulum Astrolabe Subject The topic of the resource Astronomy Navigation Surveying Optical instrument Measuring instrument Description An account of the resource The Willis Pendulum Astrolabe was used primarily by the armed forces to determine latitudes and longitudes. The astrolabe is stored in a large green wooden box. It is marked “PENDULUM ASTROLABE David White Co. Milwaukee Wisc USA, No. 65649, M-5107, 1952, U.S.” The instrument was invented by John Willis> The advantage of the Willis pendulum was that it used a mirror instead of mercury as a reflecting surface. It was able to measure position on earth to within 20 feet. The David White Company was founded in 1895 and continues to provide precision optical tools used in surveying.

Title A name given to the resource Sextants and accessories Description An account of the resource The "old astronomy" was dominated by the precise measurement of the positions of the stars and the determination of time. At Illinois, astronomy was first taught as part of the Civil Engineering department helping to develop the engineers' surveying skills. Specialized telescopes and procedures were developed for this purpose. As the "new astronomy" of astrophysics began to develop, positional astronomy was taught less and less. The one exception was the need for navigation by military ships and airplanes. In 1918 a Navigation course was offered for air service men. The course continued after WWI and was advertised as a course of interest to engineers and those thinking of working on merchant ships. This collection consists of sextants and other accessories such as artificial horizons that were used in positional astronomy, surveying, and navigation.

Title A name given to the resource Sextant and artificial horizon Subject The topic of the resource Astronomy Navigation Surveying Measuring instruments Description An account of the resource Wood, metal, glass Metal black frame with wood handle and silver scale. Horizon mirror is broken, includes 4 index filters, 3 horizon filters, 3 brass telescopes, 2 lens caps, wooden handle, 6” radius on scale, maker and model 4323 marked on index arm, vernier read by magnify lens. Box is 9 5/8” x 9 5/8” x 5 ¼” with hinge top, two latches, lock, marked “obs 14,” with metal handle. Acquired in exchange for small Fauth chronograph. Saegmuller joined Bausch and Lomb. In 1905, the company included all three names until 1907. The artificial horizon: Wood, metal, glass In the Astronomy department is the box with the cover, marked Fauth & Co. Box is 8 3/8” x 6 ¼” x 5 ¾”, dove tails visible, 2 hook latches, exterior university id tag plus paper label #6 .. Both the tray and bottle are corroded. Wind shield is greenish metal and glass. A The artificial horizon was used with sextant to determine the altitude of objects when the true horizon was not visible. They most commonly consist of a trough, bottle with mercury, and a wind shield consisting of two panes of glass at right angles to the observer’s line of sight. It was used by viewing the sun or star directly and then again in the reflection of the mercury surface. You would then have two measurements can could divide by two. In the Saegmuller catalog (page 63) it cost $30.
