distributes it evenly over the perforated spray plate. The vapor 
rises into the vapor tube of the condenser and is drawn over 
into the spray chamber surrounding it, where the vapor is con- 
densed by the spray of water issuing from the perforated spray 
plate which tops the spray chamber and which contains a large 
number of very small holes. As the water falls through these 
openings by gravity, the spray is uniform and constant and does

not depend on the amount of water used, nor does it require 
water pressure on the condenser. A complete sheet of spray al- 
ways is formed, through which the vapors must pass, regardless 
of the amount of water used, a fact which assists in the efficient 
use of the water and in rapid and complete condensation of the 
vapors. Manholes with covers are located at the top to facili- 
tate the cleaning of the spray plate.
