E. Howard & Company Astronomical Regulator. Ca. 1916. E. Howard & Co made Astronomical Regulators for many of the finest astronomical observatories in the USA. The famous Howard #74 Astronomical Regulator, which is shown in Derek Roberts "Precision Pendulum Clocks" was made in the 1870's and 1880's. This clock is a later version. The oak case is 55" tall, 19" wide and 9" deep. The heavy brass dial is silvered, engraved and filled. The weight driven movement has a deadbeat escapement with maintaining power and a 2 vial mercury filled temperature compensating pendulum. The inside of the great wheel of the movement is signed "Fitted up by C. A. Hinckley, Roxbury, Mass, Apr. 24, 1916". The movement is also fitted with the original break circuit mechanism. The movement is wound through the side of the case eliminating the need to open the door and possibly disturb the air and pendulum inside. As expected, the clock is a very fine timekeeper. By oral history and a return address on an envelope of break circuit parts that came with the clock, the clock was owned by the UCLA Department of Astronomy. There is also an old card that states " Set to sidereal time for longitude 7h 56m 29s West" which goes through the Los Angeles, CA. area. The previous owner bought the clock from the stepson of Dr. George O. Abell who was an astronomy professor at UCLA for 17 years and was best known for his observations of clusters and superclusters of galaxies. His ''Abell Catalogue of Clusters of Galaxies'' is a standard reference. The stepson got the clock from his mother, Abell's widow. The clock is in fine original condition.
