Claim 1
Independent Claim
312 words
In combination with a flexible hose having one end adapted to be connected to a holding tank at a first elevation and another end adapted to be connected to a sewer at a lower elevation than said first elevation, whereby said hose inclines downwardly from the tank to the sewer, a plurality of hose cradles each comprising: a one-piece, U-shaped trough having a length of approximately 10-12 inches, a first end and a second end; a first pair of legs having upper ends and lower ends, each of said upper ends being provided with an aperture, said lower ends being connected together in spaced-apart relation by a bight portion; a second pair of legs having upper ends and lower ends, each of said upper ends being provided with an aperture, said lower ends being connected together in spaced-apart relation by a bight portion of greater length than the bight portion on said first pair of legs, whereby said first pair of legs will nest inside said second pair of legs; first means engaging associated ones of said apertures for pivotally connecting said upper ends of said first pair of legs to one end of said trough; second means engaging associated ones of said apertures for pivotally connecting said upper ends of said second pair of legs to the other end of said trough, said second means including a spacer for each of said upper ends of said second pair of legs for maintaining said second pair of legs in a spaced-apart relation having a greater span than the distance between the upper ends of said first pair of legs, whereby said first pair of legs will nest inside said second pair of legs; and third means for readily and easily maintaining each pair of said upper ends in selected rotated positions, whereby the slope and height of said trough may be varied.
