Joztrnal an article on the Worthington Cooling Tower, I was reminded of a device used by me for the same purpose while erecting the machinery in a flour-mill at Hamburg in I862.
The engine was a Woolf beam engine (cylinders 24 and 45 inches diameter), and the discharge from the air-pump was carried to the roof of the boiler-house (a low structure, adjoining the mill), over which the e0ndensing water ran, passing over a number of ridges formed on the roof (whieh was of tin), and then'falling into a well, from which it was again taken for injection into the condenser.
In this manner the condensing water was sufficiently cooled to give a vacuum of 24 to 25 inches in winter and 22 to 23 inches in summer.
Hoping this may be of interest, I remain, Yours truly, JOHN HAUG.
