Škoda-Sentinel "Super Sentinel" steam wagonThe Sentinel boiler was a design of vertical boiler, fitted to the numerous steam wagons built by the Sentinel Waggon Works.. The boiler was carefully designed for use in a steam wagon: it was compact, easy to handle whilst driving, and its maintenance features recognised the problems of poor feedwater quality and the need for it to be maintained by ...
When part definition is defined mathematically via a solid model, the assertion that one cannot interrogate the model—the direct analog of "scaling the drawing"—becomes ridiculous; because when part definition is defined this way, it is not possible for a drawing or model to be "not to scale". A 2D pencil drawing can be inaccurately ...
A list, usually tabular and often on the drawing (if not accompanying the drawing on a separate sheet), listing the parts needed in an assembly, including subparts, standard parts, and hardware. There is no consistently enforced distinction between an L/M, a BoM, or a P/L. PLM: product lifecycle management; plant lifecycle management: See also ...
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 ...
An engine operating with no cut-off but a throttled steam supply will be operating inefficiently, owing to reduced expansive working and the risk of wire-drawing. The first 'automatic' governors were termed that because they not only controlled the speed, but could also take over the role of the driver and could vary cut-off too. [8] [9]
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.
Makers of miniature working steam engines (i.e. "live steam") to be used as educational toys. Note that some of these companies no longer produce toy steam engines today. Wikimedia Commons has media related to Model steam engine manufacturers .
