This invention relates to water eliminators'for
use at the top of cooling towers and has for its
general object to produce an eliminator assembled
lin sections or units‘of a plurality of'serpentine
5 or zigzag passageways, so- that the eliminators
may be placed in or removed from operative po
sition for repair or other purposes, without neces
sitating the services of a carpenter or other ex

In the construction shown the grills are of such
length and width respectively, as to provide
eliminator units capable of receiving in threaded 15

With a construction embodying the invention
the louver slats 5 may be assembled in threaded
loose relation with 'the desired number of grills,
depending on the lengths of the slats which is de
termined by the span to be bridged or the width
of the cooling tower. In the construction shown
in Figure l, four grills are illustrated in support

of the eliminator. In practice, it has been found
