Opening claim text (preview).
The invention claimed is: 1 . An agitator for a gypsum wallboard mixer, the mixer including an annular lid ring having a diameter and connected to and depending from an inner surface of an upper wall, said agitator comprising: a circular disc with an upper surface; a drive shaft extending vertically from said upper surface; a lump ring secured to said upper surface, said lump ring having a diameter just smaller than said annular lid ring and being provided in three spaced, adjacent arcuate segments, each said segment extending approximately 120° of a circle defined by said lump ring; and wherein gaps are formed between ends of said adjacent segments. 2 . The agitator of claim 1 , wherein said circular disc has a vertical axis, and said drive shaft is mounted to said circular disc at said vertical axis. 3 . The agitator of claim 1 , wherein said three segments are of equal length. 4 . The agitator of claim 1 , wherein said gaps range from ⅜ to 2⅝ inches. 5 . The agitator of claim 1 , wherein said lump ring is ⅜ inch tall. 6 . The agitator of claim 1 , further including at least one pin projecting from said upper surface of said circular disc. 7 . The agitator of claim 1 , wherein an upper edge of said lump ring overlaps a lower edge of the lid ring to create a serpentine path for the slurry as the slurry migrates radially outwardly due to centrifugal force. 8 . A slurry mixer, comprising: an upper wall and a lower wall, with an annular peripheral wall attached to and vertically separating said upper and said lower walls, said upper, lower and annular peripheral walls defining a chamber, an annular lid ring having a diameter and connected to and depending from an inner surface of said upper wall; at least one inlet in at least one of said upper wall and said lower wall; a circular disc with an upper surface disposed in said chamber; a drive shaft extending vertically from said upper surface and projecting from said upper wall; a lump ring secured to said upper surface, said lump ring having a diameter just smaller than said lid ring and being provided in three spaced, adjacent arcuate segments each extending approximately 120° of a circle defined by said lump ring; and wherein gaps are formed between ends of said adjacent segments and wherein an upper edge of said lump ring overlaps a lower edge of the lid ring to create a serpentine path for the slurry as the slurry migrates radially outwardly due to centrifugal force. 9 . The mixer of claim 8 , wherein said lump ring is provided in three equal length segments. 10 . The mixer of claim 8 , wherein said gaps range from ⅜ to 2⅝ inches. 11 . The mixer of claim 8 , wherein said lump ring is ⅜ inch tall. 12 . The mixer of claim 8 , further including at least one agitating formation projecting from said upper surface of said circular disc. 13 . The mixer of claim 12 , wherein said at least one agitating formation is a pin.
