Ice making machine

Victorian illustration to download showing a large ice making machine driven by belts and powered by steam. It worked through the evaporation of ether, which cooled salt water circulating round fresh water in the troughs (to the left of the picture). The water froze in slab-shaped moulds – the attendant is removing the slabs of ice and piling them up. This machine was invented in 1858 by an Australian, Mr Harrison, and it could produce from 8,000 lb to 10,000 lb of ice per day.
