Abstract

Abstract An apparatus for cleaning disks includes an enclosed housing with an operable door therein adapted to permit access to the interior of the housing. A rack is removably mounted within the housing, and will retain a plurality of disks in parallel spaced-apart relation within a disk-retaining cradle within the housing. The disk-retaining cradle is operably mounted so as to rotate about an axis passing through the centers of all of the disks. A spray bar projects within the housing and through all of the central openings in each of the disks, and has a plurality of spray nozzles therein to spray fluid radially outwardly therefrom to cover all of the disks, as they rotate in the cradle. A method for cleaning disks includes the initial step of providing a housing with an operable door and a cradle therein adapted to rotate a plurality of disks. The disks to be cleaned are then loaded in a rack which retains the disks in parallel spaced-apart orientation, which is loaded in the cradle within the housing. A spray arm within the housing projects through the central openings of the disks as the disks are loaded within the housing. Once the door is shut, the cradle is operated so as to rotate, thereby rotating all of the disks. Fluid is then sprayed from the spray arm onto the disks as they rotate.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 95 words
An apparatus for cleaning disks, the disks being of the type having a central opening therethrough comprising: an enclosed housing; a door in said housing operable between open and closed positions to permit access to the interior of said housing; disk retaining means operably mounted in said housing and operable to rotate a plurality of disks about a longitudinal axis perpendicular to the disks and passing through their centers; spray arm means mounted within said housing and projecting generally coaxial with the rotational axis of said disk retaining means for spraying fluid on said disks.
Claim 2
Independent Claim 95 words
An apparatus for cleaning disks, the disks being of the type having a central opening therethrough comprising: an enclosed housing; a door in said housing operable between open and closed positions to permit access to the interior of said housing; disk retaining means operably mounted in said housing and operable to rotate a plurality of disks about a longitudinal axis perpendicular to the disks and passing through their centers; spray arm means mounted within said housing and projecting generally coaxial with the rotational axis of said disk retaining means for spraying fluid on said disks.
Claim 3
Dependent Claim 33 words
The disk cleaning apparatus of claim 1, wherein said spray arm includes a plurality of openings arranged therein to direct a spray of fluid uniformly outwardly from the entire circumference of the arm.
Claim 4
Dependent Claim 32 words
The disk cleaning apparatus of claim 2, wherein said spray arm openings are arranged longitudinally along said arm from end to end, to uniformly spray fluid on all disks within said housing.
Claim 5
Dependent Claim 33 words
The disk cleaning apparatus of claim 1, further comprising a rack removably connected to said disk-retaining means, for retaining a plurality of disks in generally parallel, spaced-apart orientation aligned along a single axis.
Claim 6
Dependent Claim 19 words
