Grasshopper Steam Engine, c. 1851
- Made:
- 1851 in unknown place
Grasshopper beam engine, from the South London Brewery, Southwark, possibly by Easton and Amos, c. 1851
This engine was used at the premises of the South London Brewery Ltd at 134 Southwark Bridge Road, London. It would have been used as many brewery engines are, to pump water and beer during the course of the brewing process. The brewery was run by R&H Jenner from 1831 until 1938, and the engine's 1851 date is supported by the square rimmed flywheel design, which predated the round rimmed design popular in the 1860s. The engine is very similar in detail to others built by Easton and Amos, who were close to the brewery, and these details, including the centrifugal governor and decorative knops to components such as the connecting shaft, even make it a preferable and more interesting design than the later examples (inv. 1975-202, for instance).
