Portable support apparatus for evaporative cooling

Claim 1

A lightweight, portable support apparatus for pressurized water conveyance and mist spraying nozzles for overhead evaporative cooling purposes, said apparatus comprising, (a) a single rear elongated leg extending outwardly and rearwardly along a longitudinal center line axis of said apparatus, two front elongated legs of equal length being oppositely attached to an upper end-portion of said rear elongated leg, such that each of said front elongated legs extends forwardly and laterally outward from said longitudinal center line axis of the apparatus in a substantially oblique direction, substantially horizontal support ties interconnecting a lower end-portion of all three legs for positioning and support; (b) a boom attached to the upper end-portion of said rear elongated leg and extending forwardly and upwardly in substantial alignment with the longitudinal axis of the rear leg, said boom having conduit means for conveying water under pressure; (c) a truss post affixed at substantially right angles to a top side of the upper end-portion of the rear leg, a lower truss member interconnecting the lower end-portion of the rear leg and an outer end-portion of said truss post, an upper truss member interconnecting said outer end-portion of the truss post and an outer end-portion of the boom; (d) at least one substantially upright pivot post attached to the outer end-portion of the boom, a plurality of branch arms, pivot means for pivotally attaching an inner end-portion of each of said branch arms to a lower portion of said at least one pivot post, said branch arms extending radially outward from said pivot means, the branch arms having conduit means for conveying water under pressure, at least one mist spraying nozzle attached to each branch arm, a plurality of support guys, each one of said support guys having pivot means for pivotally attaching to an upper portion of said at least one pivot post, at least one of said plurality of support guys extending radially outwardly and downwardly from said upper portion of said at least one pivot post and attaching to at least one of said branch arms, each support guy having adjustable means for lengthwise adjustment, at least one flexible support stay interconnecting each branch arm and the boom for radial positioning and support, said flexible support stay having two ends and each end having quick-release means for easy removal from the boom, a flexible water conduit interconnecting said conduit means of the boom and said conduit means of each branch arm, said flexible water conduit having a quick-disconnect coupling, a filtering means for filtering water between said quick-disconnect coupling and said at least one mist spraying nozzle, a support tie interconnecting the upper portion of said at least one pivot post and a lower and substantially central point of the apparatus; and (e) a counter-balance means for counter-balancing the forward weight of the apparatus being provided at the lower end-portion of the rear leg.
