	Egide Walschaerts - Wikipedia, the free encyclopedia
		Egide Walschaerts (21 January 1820 - 1901) was a Belgian mechanical engineer, best known as the inventor of the Walschaert valve gear for use in steam engines.
		Born in Mechelen, Belgium, Walschaerts studied at Liège, and in 1842 joined the Belgian State Railway workshops.
		The gear, known as the Walschaert Gear in his honor, allows for adjustment of the timing of the inlet and exhaust valves on the drive cylinders, enabling a steam locomotive to be put into reverse.

	Walschaert valve gear - Wikipedia, the free encyclopedia
		The Walschaert or Walschaerts valve gear is a type of steam engine valve gear invented by Belgian railway mechanical engineer Egide Walschaerts in 1844.
		The Mason Bogie locomotive type was the first to use the Walschaert gear in North America.
		To layout the Walschaert gear the proportions of the combination lever must be chosen.

	Continental engineers
		Walschaerts, a foreman of the Belgian State Railway, made several inventions of which one, his valve gear, was very successful and was widely used throughout the world, especially for outside cylinder locomotives in the twentieth century.
		The Belpaire boiler and Walschaert's valve gear were both Belgian products, and both belonged to that group of innovations which seemed to their inventors not to create a revolution, but simply to promise a better way of doing things.
		Egide Walschaert was born in Malines in 1820 and died near Brussels in 1901.

	4 Cylinder Engines
		The scissors gear was not repeated, and when further engines were ordered, Pearce designed inside valve gear based on the invention of Belgian Egide Walschaerts (pronounced val-shirts).
		Walschaerts valve gear, which was a novelty in the UK, became as common in the steam age as the jet engine is today.
		Its main benefit is a derived motion from the piston crosshead via a combination lever that causes it to dwell at the end of its valve travel, giving greater ingress of steam.

	Steam Locomotive Walschaert Gear Diagram
		Invented in 1844 by Egide Walschaerts, foreman of the Belgian State Railway
		The motion must be adjusted with the crank on the dead centers by lengthening or shortening the eccentric rod until the link takes such a position as to impart no motion to the valve when the link block is moved from its extreme forward to its extreme backward position.
		Slight variations may be made in the cutoff points as covered by the preceding paragraph but an independent adjustment cannot be made except by shifting the location of the suspension point which is preferably determined by a model.

	It's A Joy
		Egide Walschaert (1820 - 1901) was born in Malines, Belgium.
		The first use of Walschaerts valve gear on a British locomotive was as early as 1846, on a Fairlie 0-6-6-0, but it only really gained popularity in Britain the 1920s.
		These locomotives used his self-designed valve gear, which was chain driven and oil immersed in a sealed case installed between the frames.

	Steam Locomotive Walschaert Valve Gear Animation
		By the way, Walschaert gear is correct; Walschaerts gear is not (unless it is used in the possessive case, with an apostrophe, eg: "Walschaerts' design").
		The inventor's name was (Egide) Walschaerts (pronunciation: ay-gee-day val-sherts), but the design was patented under the name Walschaert for political reasons.
		We're Mac heads here, but we downloaded his.exe files and borrowed a Wintel machine to try them out and were impressed with this work; very cool and enlightening.

	Train and Railroad \| World of Invention
		As rail lines spread and grew in importance, demand increased for higher speeds and greater efficiency.
		Belgian engineer Egide Walschaerts improved the valve gear in 1844, and by 1847 Britain's Great Western Railway ran some routes at 60 mph (90.5 kph).
		In 1859 greater rail adhesion was achieved with coupled driving wheels.

		The 5AT will resemble a conventional Stephensonian steam locomotive, yet it will be neither smoky nor grimy.
		Yes, it will produce that familiar rhythmic beat, those plumes of white steam; its piston rods will race in and out of visible cylinders, and its tall disc wheels will be driven by a form of reciprocating motion invented by the Belgian engineer Egide Walschaerts in 1844.
		Otherwise, it will be a very different machine, 100% more efficient than the finest steam locomotives of the 1950s when technical development of this much loved form of motive power hit the buffers.
