Hello listers,
In the area where I currently work (Chillagoe, North Queensland) one of the old mines (Girofla) was notably wet and pumping was conducted in the 1920s by means of a vertical pump rod attached to a 'balance bob' which sat in line with a horizontally acting steam engine. I presume there was a connecting rod between the fly-wheel and the top of the 'balance bob'. Was this a common pumping arrangement at that time ? How many 'sweeps' per minute might the pump rod typically achieve with this configuration ? Any thoughts welcomed.
Regards
Ian Hodkinson
