No. 14574.—3rd March, 1902.—CLIFTON HAROLD
WHEELER, of Forest Drive, Short Hills, New Jersey,
United States of America, Mechanical Engineer. Im-
provements in cooling-towers for reducing the tempera-
ture of condensing-water and other fluids.

Claims.—(1.) In a cooling-tower, the combination with
devices for supplying fluid to be cooled, mats placed verti-
cally and spaced apart, and devices for suspending the mats
at their upper ends, of adjustable hook devices connected to
the lower ends of the mats and supports below the mats
through which the said devices pass, whereby the mats are
held firmly at their lower ends and under adjustable tension,
substantially as set forth. (2.) In a cooling-tower, the com-
bination with devices for supplying fluid to be cooled, mats
placed vertical and spaced apart, and devices for suspend-
ing the mats at their upper ends, of angle-irons extending
through the tower below the mats, strips of metal secured
to and along the lower ends of the mats, and hooks with
threaded stems engaging the mats at the strips of metal and
passing through the angle-irons, and nuts upon the stems of
the hooks below the angle-irons for drawing down the mats
and applying a tension thereto and taking up the slack,
