| Description: |
- 3D-Printed replica of an early 20th-century Pilkington & Gibbs Heliochronometer. In 1906, G. Gibbs applied for a patent for a novel sundial design—the Universal Equinoctial Mean Time Heliochronometer. This sundial represented a technical pinnacle of early modern sundials, combining mechanical ingenuity with practical timekeeping capabilities. Its integration of latitude, longitude, and Equation of Time corrections via a mechanical cam assembly allowed users to determine mean time with remarkable accuracy for its era.
Notice on the time mark is a straight line, not an analemma curve. The Equation of Time transfer from solar time to civil time was, as noted, uses a patented mechanical cam.
