English: These shots were hard to get because of the wire put around the mechanism to protect it.
Kerosene gas light mechanism of Walton Harbour Lighthouse. The light apparatus consisted of two flat-wick kerosene lamps. The light was magnified by a Fresnel lens with a 16" reflector. A black screen revolved around the outside of the lamp so that the light was visible at 3 different intervals, through a repeating cycle. The screen was operated by a clock mechanism, it was wound by hand each night by cranking a handle. Three galvanized iron tanks were used to store the oil for the lamps. Abraham Pineo Gesner (May 2, 1797 - April 29, 1864) was a Canadian physician and geologist who invented kerosene. Gesner was born in Cornwallis, Nova Scotia. He died in Halifax, Nova Scotia. Walton Harbour Lighthouse was deactivated in 1986. The restored lighthouse and grounds have been developed into an interpretation center. |
