The factory produced hot bulb engines and spare parts for them from 1908 up to closure of the workshop in 1979.
The engine factory is an industrial heritage site, complete with functioning production lines and offices.
However, these plans failed and the factory instead started producing locks, brass candlesticks and electrical fittings.
Pythagoras manufactured hot bulb engines under the trademarks of Fram and Drott, the latter for export markets.
Nowadays the Pythagoras Engine Factory is recognized as one of the most valuable industrial heritage monuments in Sweden.
