Abstract
Abstract A fill assembly for a cooling tower comprising a plurality of fill strips positioned within the fill area, a plurality of spaced apart vertically suspended fill hangers positioned transversely with respect to said fill strips within said fill area, said fill hangers having a plurality of substantially horizontally and generally vertically extending members which intersect one another to form a plurality of parallelogram grids, each of said fill strips being supported by a horizontal portion of one of said parallelogram grids of at least two of said fill hangers, and each of said parallelogram grids including means associated with said vertically extending members to retain said fill strips in a predetermined position relative to said horizontal portion. Also provided are unique snap-lock joints to attach adjacent fill hanger sections and horizontal and transverse stabilizers to increase the stability of the fill assembly.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
280 words
In a cooling tower wherein air is displaced to flow directionally generally laterally within the tower in cooling relation with dropping particulate liquid having a splash fill assembly positioned within the fill area of said tower, an improved fill assembly comprising: a. a plurality of fill strips positioned within said fill area; b. a plurality of spaced apart vertically suspended fill hangers positioned transversely with respect to said fill strips within said fill area, said fill hangers comprise a plurality of substantially horizontally and generally vertically extending members which intersect one another to form a plurality of parallelogram grids; c. each of said fill strips being supported by the horizontal portion of one of said parallelogram grids of at least two of said fill hangers; d. each of said fill hangers including a plurality of fill hangers sections which are attached one atop of another and one along side of another; e. connecting means integral with said vertical members to connect said fill hanger sections one atop of another; and f. horizontal stabilizer means to connect said fill hanger sections one alongside another and space said fill hangers a predetermined distance apart, said horizontal stabilizer means comprises a substantially horizontal strap having a U-shaped cut-out at each end defining a pair of leg portions, said horizontal stabilizer means being positioned parallel to said fill strips between adjacent fill hangers so as to permit one leg of each end to be crimped about a horizontal member of one fill hanger section and the other leg of each end to be crimped about a horizontal member of a fill hanger section along side thereof with a vertical member of each section therebetween.
