In order to provide for complete drainage, at least two channels are formed in the top surface of the cover. The channels slope downwardly from a location proximate the valve stem of the fire hydrant to a location opposite a portion of the valve body. ## Claims ### Claim 1 A cover for a fire hydrant that includes a valve body having a valve stem extending upwardly therefrom, said cover comprising: a cup-shaped dome defined by a wall that is adapted to be positioned over and around the valve body; means for coupling said dome to the fire hydrant; an opening in said dome for rotatably receiving a tool that is adapted to mate with and angularly displace the valve stem between open and closed positions; and elongated and downwardly sloping drainage means formed in the outer surface of the wall of said dome, said drainage means having a first upper end positioned at a location proximate the valve stem and a second lower end positioned at a location opposite a portion of the valve body, said drainage means being further defined by side wall means connected to each other such that all surfaces of said drainage means are completely open to the atmosphere and face away from the interior of said dome throughout their entire length whereby fluid and/or debris can drain therefrom without collecting. ### Claim 2 (depends on 1) The cover according to claim 1 wherein said drainage means are defined by at least two diametrically opposed channels. ### Claim 3 (depends on 2) The cover according to claim 2 wherein each of said channels include a pair of opposed side walls and a base wall connecting said side walls. ### Claim 4 (depends on 3) The cover according to claim 3 wherein at least said base wall is arcuate. ### Claim 5 (depends on 3) The cover according to claim 3 wherein said side walls and said base wall are flat. ### Claim 6 (depends on 2) The cover according to claim 2 wherein each of said channels is substantially U-shaped in transverse cross-section. ### Claim 7 (depends on 2) The cover according to claim 2 wherein each of said channels is substantially V-shaped in transverse cross-section. ### Claim 8 (depends on 2) The cover according to claim 2 wherein said coupling means are located intermediate said channels. ### Claim 9 (depends on 1) The cover according to claim 1 wherein said drainage means are defined by three equally spaced apart channels. ### Claim 10 (depends on 9) The cover according to claim 9 wherein each of said channels includes a pair of opposed side walls and a base wall connecting said side walls. ### Claim 11 (depends on 10) The cover according to claim 10 wherein at least said base wall is arcuate. ### Claim 12 (depends on 10) The cover according to claim 10 wherein said side walls and said base walls are flat. ### Claim 13 (depends on 9) The cover according to claim 9 wherein each of said channels is substantially U-shapoed in transverse cross-section. ### Claim 14 (depends on 9) The cover according to claim 9 wherein each of said channels is substantially V-shaped in transverse cross-section. ### Claim 15 (depends on 9) The cover according to claim 9 wherein said coupling means are intermediate said channels. ### Claim 16 (depends on 1) The cover according to claim 1 wherein said drainage means are defined by at least four equally spaced apart channels. ### Claim 17 (depends on 16) The cover according to claim 16 wherein each of said channels includes a pair of opposed side walls and a base wall connecting said side walls. ### Claim 18 (depends on 17) The cover according to claim 17 wherein at least said base wall is arcuate. ### Claim 19 (depends on 17) The cover according to claim 17 wherein said side walls and said base wall are flat. ### Claim 20 (depends on 16) The cover according to claim 16 wherein each of said channels is substantially U-shaped in transverse cross-section. ### Claim 21 (depends on 16) The cover according to claim 16 wherein each of said channels is substantially V-shaped in transverse cross-section. ### Claim 22 (depends on 16) The cover according to claim 16 wherein said coupling means are intermediate said channels. ### Claim 23 (depends on 2) The cover according to claim 2 wherein the top of the wall of each said channel is, in the assembled condition, in substantially the same plane as the top of the valve stem. ### Claim 24 (depends on 1) The cover according to claim 1 wherein the top of said dome is, in the assembled condition, above the top of the valve stem.
