Claim 3
Dependent Claim
20 words
The liquid cooling tower construction of claim 1 wherein: a. each of said pegs releasably snaps into said frame sockets.
Claim 4
Dependent Claim
27 words
The liquid cooling tower construction of claim 1 wherein: a. each of said frames carries a plurality of sockets at its corners which receive the said pegs.
Claim 5
Dependent Claim
27 words
The liquid cooling tower construction of claim 1 wherein: a. said support brackets are vertically spaced from each other by tubes through which said flexible members pass.
Claim 6
Dependent Claim
24 words
