Description
Vancouver, BC, Canada
Info from wiki:
Gastown's most famous (though nowhere near oldest) landmark is its steam-powered clock, located on the corner of Cambie and Water Street. Built to cover a steam grate, part of Vancouver's distributed steam-heating system, the clock was built as a way to harness the steam and to prevent street people from sleeping on the spot in cold weather. Its original design was faulty and it had to be powered by electricity after a breakdown. The steam mechanism was completely restored with the financial support of local businesses as it had become a major tourist attraction, and is promoted as a heritage feature although it is of modern invention. The steam used is low pressure downtown-wide steam heating network (from a plant adjacent to the Georgia Viaduct) that powers a miniature steam engine in its base, in turn driving a chain lift. The chain lift moves steel balls upward, where they are unloaded and roll to a descending chain. The weight of the balls on the descending chain drives a conventional pendulum clock escapement, geared to the hands on the four faces. The steam also powers the clock's sound production as whistles are used instead of bells to produce the Westminster "chime" and to signal the time.
Although they are often styled to appear as 19th-century antiques, steam clocks are a more recent phenomenon inspired by the Gastown steam clock built by Saunders in 1977. One exception is the steam clock built in the 19th century by Birmingham engineer John Inshaw to demonstrate the versatility of steam power.
Raymond Saunders' first steam clock was built in 1977 as a tourist attraction for the renovated Gastown district of Vancouver. Although the clock is now owned by the City of Vancouver, funding for the project was provided by contributions from local merchants, property owners, and private donors. Incorporating a steam engine and electric motors, the clock displays the time on four faces and announces the quarter hours with a whistle chime that plays the Westminster Quarters.
