A Brief History of the Marque
Manufactured: Job Day and Sons of Leeds
The firm marketed motorcycles under the brands Day-Leeds and Eclipse. These were produced from around 1912 until the beginning of the Great War and were developed by William Henry Day, son of Job Day. The firm was well established and built a variety of machinery for food processing and packaging.
In addition to motorcycles they built cyclecars, all powered by their own engines which were somewhat advanced for the day having overhead inlet valves.
The Eclipse was probably very similar to the Day-Leeds, with a 499cc engine, Edlin frame, Druid forks, Bosch magneto, and a compression release. The motorcycles, designed by designed by H. A. Smith, came in direct belt drive or two-speed versions.
N.B. There was an earlier Eclipse made in Birmingham. Eclipse
