Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.
A live steam festival (often called a "Steam Fair" in the UK and a live steam "meet" in the US) is a gathering of people interested in steam engine technology. Locomotives, trains, traction engines , steam wagons , steam rollers , showman's engines and tractors , steam boats and cars , and stationary steam engines may be on display, both full ...
Weeden Vertical toy steam engine in the 1912 Sears, Roebuck and Co. catalog. In the late 19th century, manufacturers such as German toy company Bing introduced the two main types of model/toy steam engines, namely stationary engines with accessories that were supposed to mimic a 19th-century factory, [4] and mobile engines such as steam locomotives and boats.
Murdoch's model steam carriage of 1784, now in Thinktank, Birmingham Science Museum. Early research on the steam engine before 1700 was closely linked to the quest for self-propelled vehicles and ships [citation needed], the first practical applications from 1712 were stationary plant working at very low pressure which entailed engines of very large dimensions.
An oscillating cylinder engine cannot be reversed by means of the valve linkage (as in a normal fixed cylinder) because there is none. Reversing of the engine can be achieved by reversing the steam connections between inlet and exhaust or, in the case of small engines, by shifting the trunnion pivot point so that the port in the cylinder lines up with a different pair of ports in the port face.
Stevens Model Dockyard was as much a retailer as a maker and large numbers of items are now claimed to be by the company that were only retailed by them, rather than made by them. There is little evidence of what exactly they made prior to 1900, but certainly ship models, fittings and engines, spirit fired steam locomotives, wooden rolling ...
Model live steam locomotives predominate as the most popular modelling subject in model engineering. [7] As such they deserve special mention. Live steam refers to the use of pressurised steam, heated in the model locomotive's own boiler, to turn the wheels via miniature steam cylinders. Not all locomotives are live steam - some model engineers ...
The company introduced high-pressure steam engines to the riverboat trade in the Mississippi watershed. The first high-pressure steam engine was invented in 1800 by Richard Trevithick. [44] The importance of raising steam under pressure (from a thermodynamic standpoint) is that it attains a higher temperature. Thus, any engine using high ...
