Dear List,
Can anyone tell me how (if at all) very early C19 pumping machinery in
shafts differed from the later (ie: c.1840-1900) setups, as shown in the
Harveys and Williams catalogues.
I am aware that they were bucket-lifts, plungers being a later refinement,
but don't know whether cast iron valve chests were in use, or even what they
and their pipework looked like.
I am trying to draw accurate elevations of such things for a book
illustration and don't want to get anything wrong - I know how pedantic
mining historians can be - I am one after all!
The geographical area concerned is Devon/Cornwall.
Yours,
Robert Waterhouse
