Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 308 words
An improved humidifying apparatus comprising: a. a fan assembly inclusive of i. a shaft, ii. a hub member mounted to rotate on said shaft, said hub member having a chamber formed therein to serve as a water plenum; and iii. fan blades mounted to extend from said hub member; b. means to deliver water to said chamber; c. a slinger assembly mounted to rotate coaxial with, independent of and adjacent to said hub member, said slinger assembly inclusive of i. a first disc-shaped plate having, on its face nearest said hub member, three or more vanes mounted on said nearest face to extend radially inward from the periphery of said first plate to define channels between adjacent vanes; and ii. a second disc-shaped plate mounted face to face with said first plate such that said vanes are between said faces and the channels formed by said vanes are enclosed, said second plate having a cylindrical passage formed in the center thereof; d. three or more water-carrying conduits, said conduits extending from said chamber through the end of said hub member to protrude from said hub member and through said cylindrical passage of said second plate to adjacent said nearest face of said first plate such that said conduits extend within said slinger assembly, said conduits being equally spaced radially from said shaft to define a circle on which said conduits are evenly spaced so that said conduits evenly distribute water from said chamber onto said nearest face of said first plate such that water is impelled outwardly from said slinger assembly by centrifugal force; and e. a tubular member coaxially mounted to said hub member to rotate therewith, said tubular member including a plurality of fins spaced circumferentially from one another to form a cylindrical array which extends outward from said hub member to circumscribe said slinger assembly.
Claim 2
Dependent Claim 308 words
An improved humidifying apparatus comprising: a. a fan assembly inclusive of i. a shaft, ii. a hub member mounted to rotate on said shaft, said hub member having a chamber formed therein to serve as a water plenum; and iii. fan blades mounted to extend from said hub member; b. means to deliver water to said chamber; c. a slinger assembly mounted to rotate coaxial with, independent of and adjacent to said hub member, said slinger assembly inclusive of i. a first disc-shaped plate having, on its face nearest said hub member, three or more vanes mounted on said nearest face to extend radially inward from the periphery of said first plate to define channels between adjacent vanes; and ii. a second disc-shaped plate mounted face to face with said first plate such that said vanes are between said faces and the channels formed by said vanes are enclosed, said second plate having a cylindrical passage formed in the center thereof; d. three or more water-carrying conduits, said conduits extending from said chamber through the end of said hub member to protrude from said hub member and through said cylindrical passage of said second plate to adjacent said nearest face of said first plate such that said conduits extend within said slinger assembly, said conduits being equally spaced radially from said shaft to define a circle on which said conduits are evenly spaced so that said conduits evenly distribute water from said chamber onto said nearest face of said first plate such that water is impelled outwardly from said slinger assembly by centrifugal force; and e. a tubular member coaxially mounted to said hub member to rotate therewith, said tubular member including a plurality of fins spaced circumferentially from one another to form a cylindrical array which extends outward from said hub member to circumscribe said slinger assembly.
Claim 3
Dependent Claim 39 words
An improved humidifying apparatus according to claim 1 wherein said first disc-shaped plate further includes circumferentially spaced fins mounted to protrude from said nearest face of said first plate, said fins defining a plurality of slots between adjacent vanes.
