steam clock

Steam clocks by other makers are installed in St Helier, Jersey and at the Chelsea Farmers' Market in London, England. • Illustration — Tourists entertained by the Gastown steam clock in Vancouver 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.

In 1859, engineer and businessman John Inshaw took over the public house on the corner of Morville Street and Sherborne Street in Ladywood, Birmingham, UK. In a bid to make the establishment a talking point in the area, as well as furnishing it with various working models, Inshaw applied his interest in steam power to construct a steam-powered clock as a feature. A small boiler made steam; the steam condensed into droplets of water that fell on a plate at regular intervals, and the plate then drove the mechanism. The clock was installed above the door, and the pub became known as the Steam Clock Tavern. The establishment was sufficiently successful that it became a music hall in the 1880s.

It was built to cover a steam grate, part of Vancouver's distributed steam heating system, as a way to harness the steam and a means of masking Central Heat's sidewalk steam vent at the corner of Water Street and Cambie Street. Although the clock is now owned by the City of Vancouver, funding for the project, estimated to be about $58,000 CAD, 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. The clock produces a puff of steam from its top on the hour. The steam used is from a low pressure downtown-wide steam heating network, from a plant adjacent to the Georgia Viaduct, that powers a miniature steam engine in its base, 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, with whistles being used instead of bells to produce the Westminster "chime" and to signal the time. The steam engine that originally ran the clock is a Stuart #4 single-expansion double-acting 1" piston engine. This engine is still visible through the glass sides of the clock. However, owing to the clock's high noise levels and inability to keep accurate time, since 1986 the clock has been powered by an electric motor that was originally intended solely as a back-up system. In October 2014, the clock was temporarily removed for major repairs by its original builder, and was reinstalled January 2015. The clock appears on the cover of the Nickelback album Here and Now and is also featured in a scene from the 1991 Chuck Norris action film The Hitman. It also appears in the 2019 mobile game Mario Kart Tour and the Nintendo Switch game Mario Kart 8 Deluxe as part of the "Vancouver Velocity" race course. • Illustration — Whistles on the clock • Illustration — Front plaque on Vancouver Gastown steam clock • Illustration — Steam engine in the clock

The 17 ft–tall Indiana State Museum steam clock in Indianapolis, Indiana, is located on the sidewalk on the north side of the museum near the canal. It has four 24 in diameter dials that are backlit by neon. The clock’s eight brass whistles play a few notes of "Back Home Again in Indiana" every 15 minutes. A more complete rendition is played at the top of every hour.

The towering and quirky steam clock located at the Chelsea Farmers' Market was constructed in 1984 by Tim Hunkin. Although still standing, the clock is no longer in operation.

• Illustration — Jersey Steam Clock The Jersey steam clock is a full-scale replica of the centre section of a paddle steamboat named the Ariadne. The clock was commissioned by the Jersey Waterfront Board in 1996, and built by Smith of Derby Group. Although once powered by steam, according to a Jersey government document "the steam workings have been replaced with electrical fittings designed to provide the same functionality including the blowing of 'steam' at the appropriate times of the day." The clock is sited on the North Quay of the harbour at St Helier, Jersey, and also incorporates a fountain. It is listed in the Guinness Book of Records as the World's largest steam clock.

Located at Berwick, Australia,. Designed and built by Peter Weare at his own expense, it is a half-scale prototype for a larger clock proposed for Melbourne. The clock was dismantled in December 2010 due to vandalism. In December 2011, the city council agreed to find a new site for the clock.
