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.
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.
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.
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
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 ...
The drive shaft whose speed is being sensed is top right Porter governor on a Corliss steam engine. The devices shown are on steam engines. Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid ...
The Baker mechanism consisted of the following parts: A frame which replaced the mounting for the expansion link. It came in two basic forms, depending upon whether it was attached to the locomotive frame at both ends or only at the front. In either case it had two pivots: one forward and at the top of the frame, and one below and to the rear.
2" Scale Steam roller and traction engine models on display at Midland Model Engineering 2007. The 'classic' areas of model engineering interest are live steam models (typically steam locomotives, stationary engines, marine steam engines, Showman's engines, and traction engines), [2] internal combustion engines, [3] and clock making.
