Experiment (horse-powered boat)

The Experiment was an early nineteenth century boat powered by horses and incorporated the then novel idea of a screw propeller.

History

The Experiment was a horse-powered ferry boat. It was a twelve-ton three-mast boat drawing a few feet of water, about 100 feet long by 20 feet beam. Its driving mechanism, an in-water screw, was invented by David Grieve in 1801. The boat was constructed by David Wilkinson (some sources give his name as Varnum) in 1807 to 1810, depending on the source. It was propelled by a "goose-foot paddle" large mechanical screw propeller in the water (instead of a paddle wheel at water surface). The new technology devised by Grieve and Wilkinson was powered by eight horses on a treadmill. The horse boat technology to propel the boat upstream was originally invented by David Grieve and granted a patent February 24, 1801 in the patent category of "Boats to ascend rivers". The complete recorded patent was lost in the 1836 U.S. Patent Office fire. The novel idea of propelling vessels upstream by the use of a large mechanical screw in the water is now referred to as Ericsson’s propeller.

Experiment (locomotive)

Experiment was a steam locomotive designed and built by Richard Roberts in 1833 for the Liverpool and Manchester Railway (L&MR). The locomotive had vertical cylinders driving via bell cranks.

History

L&MR No.32Experiment was built in 1833 with vertical cylinders mounted just behind the chimney, driving the wheels via a bell crank. The locomotive also had piston valves. These valves were probably the reason that the design was not a success, rather than the bell crank transmission, which was used successfully in other locomotives. Another reason that the locomotive was not successful was steam leakage from the cylinders. Experiment was withdrawn after a few months.

Three similar locomotives were built for the Dublin and Kingstown Railway. Locomotives to this design were built for the Dundee and Newtyle Railway, but they were soon altered.

Plot

Revenge (UK band)

Revenge was a band formed by New Order bassist Peter Hook (vocals, bass, keyboards) and Lavolta Lakota and Rawhead singer Davyth Hicks (aka Dave Hicks) on guitar and vocals, together with Chris Jones (keyboards). Revenge formed during New Order's hiatus in 1989-1990 and played their final gigs in January 1993. After their industrial rock/house music hybrid album One True Passion was written and recorded, the band was joined on stage by David Potts (bass and guitar) and Ash Taylor on drums.

The band toured the first album worldwide playing gigs in Europe, North and South America and Japan in 1991. It was after the Japan tour that Hicks decided to leave, quoting "musical differences", but more with the feeling of frustration over the direction of Revenge and his own desire to return to being lead singer. He formed Rawhead in Manchester and reformed the band in Scotland in 1993.

In May 1991 the band recruited new members Brian Whittaker (bass and guitar) and Mike Hedges (drums) who debuted at the Cities in The Park Festival. After completion of touring and promoting New Order's 1993 album Republic, Hook returned to Revenge with the intention of recording a new album. However, the band soon disintegrated and Hook retained the talents of only David Potts when later forming Monaco.
