Cincinnati Ohio USA Equatorial Dial 26
The sun-clock was based on an illustration that appeared in Scientific American, with dimensions and shape of analemma calculated from data found in an almanac. An equatorial ring, with inside dimension of 16' and engraved with an hour circle, is fastened orthogonally to a meridional ring and the assembly is rotated on a polar axis until a lens focuses the image of the sun on the analemma line. Knowing the season, the month and approximate day can be read from the analemma scale and standard time to the nearest minute. from the hour circle. Dial is operable, but bearings are in need of repair. A duplicate of the 1986 sun-clock is believed to be located on the former Kroger estate in suburban Cincinnati. The dial sits atop a brick platform with capstone
 
 
Claremont California USA Equatorial Dial 505
A 90 inch diameter spherical segment equatorial dial ten feet high of masonry construction with 3D fiberglass analemmic gnomon 40 inches long. Dial terrazzo face has hour, half-hour, quarter-hour and 5-minute marks with Roman hour numerals for PST. The 5-minute marks are one inch apart. Dial face includes analemma graphic with month dates; a plaque describes how to use the analemma graphic to select which side of the gnomon shadow to use to read time. Base perimeter has 12 ceramic plaques with Zodiacal signs. Indicated time is accurate to one minute throughout the winter and to five minutes in summer. This is remarkable because the dial is located just outside a children's playground and children routinely climb on the dial and swing from the gnomon. An animation from digital images showing the gnomon shadow motion over the course of a full year is available. Dedicated as the Ralph B. Larkin Memorial Sundial. Rev. Larkin was a retired missionary who taught science to children for 17 years in Claremont. Dr. Larkin's father was Edgar Lucien Larkin, Director of the Mt. Lowe Observatory above Los Angeles 1900-1924 using a 16-inch Alvan Clark refractor telescope, described by Alvan Clark as, "the finest telescope I ever made." Ralph Larkin often said, "I grew up with a telescope." The Mt. Lowe Observatory was destroyed in a windstorm in 1928 and the Alvan Clark refractor was moved to Ricard Observatory at the University of Santa Clara, California.
