More like a mobile generating station. There is no inside to this just a small platform at the rear - you can see the steering wheel just above the rear wheel. These are called showman's engines and they provided electrical power to run lights mostly. The black cylinder on top is a chimney extension and the ladder against the rear wheel is most likely there to allow someone to climb on the roof to either set it up or take it down.
These date to a time before electricity was standardised. When you went to the next town you did know if you would have power or whether it would be AC or DC or what voltage it would be. Or even what hours it would be available for. And a brightly lit fairground when the rest of the town was mostly dark would probably have been a big draw.
I've been influenced by "The Iron Maiden", where there used footage from a Steam Fair. According to the wiki entry "the Iron Maiden was a John Fowler & Co. 7nhp showman's road locomotive" so I guess that was exactly what you described. https://en.wikipedia.org/wiki/The_Iron_Maiden
That first jpg is quite interesting. Firstly it is a damn big engine. See the different sized white covers on the front of the piston block? That shows it is a compound engine, the small cover is the high pressure cylinder and its exhaust drives the larger low pressure cylinder. Done properly it extracts more power than a simple piston. See the thing like a horizontal gearwheel at the bottom with a lot of parallel white lines below it? It is a gearwheel and below it is a cable drum wound with steel cable because this is a ploughing engine (google that for more info). The coiled up hose is the water intake you connect that up and drop the filter end into a pond or river you are passing to refill your boiler. Also you can see how the chimney can hinge forward in-case you need to get under a low bridge or something.

ReplyDeleteReally? Wow.

ReplyDeleteAh, that makes sense. So really, it wasn't something like this?:
