Abstract
Abstract For cleaning die pallet rings which may range in diameter from 18 in. to over 6 ft., and which consist of a generally cylindrical rim portion, an outer flange, and an inner flange, the cleaning apparatus includes support means consisting of a base carrying two rotatable support wheels for supporting and guiding the ring, and an adjustable guide wheel on a standard for guiding the upper periphery of the ring and supporting the ring in a vertical plane. One of the base support wheels is adjustable to accommodate rings of different size. A powered radial brush for cleaning the rim surface of the ring, is adjustably mounted on the frame to position the brush relative to a particular size of ring, and is also movable by a power cylinder into and out of engagement with the surface to be cleaned during operation. Two powered cup brushes are mounted on the frame to engage side surfaces of the ring, each of these being mounted for reciprocating movement into and out of engagement with the ring during operation by a power cylinder. The brush units may be mounted on suitable carriages for movement parallel to the plane of the supported ring, to accommodate rings of different size. An overhead frame supports a track and hoist for loading and unloading rings from the apparatus.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
212 words
Apparatus for cleaning a ring member comprising a base; first and second support units mounted on said base for rotation about spaced horizontal axes, for supporting a ring member in a generally vertical plane; a drive motor mounted on said base for driving said first rotatable support unit; carriage means, for said second support unit, adjustably mounted on said base for receiprocating movement relative to said first support unit; an upright standard mounted on said base; a carriage mounted on said standard for rectilinear movement therealong; a guide unit rotatably mounted on said last named carriage about an axis parallel to the axes of said support units; means for securing said guide unit carriage at selected positions on said standard; said support units and said guide unit defining a three point rotatable support for a ring member; at least one powered brush unit mounted on said base; and said powered brush unit comprising a platform, a rotary drive motor mounted for rectilinear movement on said platform, a rotary brush driven by said motor, power means mounted on said platform for selectively reciprocating said brush drive motor relative thereto; and said platform being mounted on said base to position said brush for powered movement into and out of engagement with a ring surface.
Claim 2
Dependent Claim
212 words
Apparatus for cleaning a ring member comprising a base; first and second support units mounted on said base for rotation about spaced horizontal axes, for supporting a ring member in a generally vertical plane; a drive motor mounted on said base for driving said first rotatable support unit; carriage means, for said second support unit, adjustably mounted on said base for receiprocating movement relative to said first support unit; an upright standard mounted on said base; a carriage mounted on said standard for rectilinear movement therealong; a guide unit rotatably mounted on said last named carriage about an axis parallel to the axes of said support units; means for securing said guide unit carriage at selected positions on said standard; said support units and said guide unit defining a three point rotatable support for a ring member; at least one powered brush unit mounted on said base; and said powered brush unit comprising a platform, a rotary drive motor mounted for rectilinear movement on said platform, a rotary brush driven by said motor, power means mounted on said platform for selectively reciprocating said brush drive motor relative thereto; and said platform being mounted on said base to position said brush for powered movement into and out of engagement with a ring surface.
Claim 3
Dependent Claim
62 words
The apparatus of claim 1 for cleaning a ring member including a rim portion and an external flange portion each of said rotatable support units comprising a first rotor having a resilient peripheral surface for engagement with the ring rim portion, and a second rotor spaced from said first rotor to define a groove for accommodating and guiding said external flange portIon.
Claim 4
Dependent Claim
62 words
The apparatus of claim 1 said means for securing said guide unit carriage comprising a second guide unit carriage mounted for rectilinear movement, means for locking said second guide unit carriage at selected positions on said standard, and at least one extensible fluid motor coupling said first and second guide unit carriages for reciprocating the first carriage relative to the second carriage.
Claim 5
Dependent Claim
26 words
The apparatus of claim 1 said power means for selectively reciprocating said brush drive motor comprising an extensible fluid motor coupling said motor and said platform.
Claim 6
Dependent Claim
80 words
The apparatus of claim 1 a plurality of said powered brush units mounted on said base; each powered brush unit comprising a platform, a rotary motor mounted for reciprocating movement on said platform, a rotary brush driven by said motor, and power means mounted on said platform for reciprocating said brush motor relative thereto; and said brush unit platforms being mounted on said base to position said brushes for powered movement into and out of engagement with respective ring surfaces.
Claim 7
Dependent Claim
87 words
The apparatus of claim 5 one of said powered brush units including a radial brush for engagement with a rim surface of said ring member, with said powered reciprocating means moving said brush in its rotating plane toward and away from the respective ring member surface; and at least one other powered brush unit including a cup brush, with the brush being movable in the direction of the rotational axis of the brush to bring the brush into engagement with a side surface of the ring member.
Claim 8
Dependent Claim
75 words
The apparatus of claim 5 each of said powered brush units including an electric rotary motor for driving its respective brush; said power means for driving said first rotatable support unit comprising an electric rotary motor; control means for said apparatus comprising a first switch means for energizing said support unit drive motor, second switch means for energizing said brush unit drive motors, and a control device for actuating the brush unit powered reciprocating means.
Claim 9
Dependent Claim
14 words
The apparatus of claim 5 said powered reciprocating means comprising double-acting pneumatic power cylinders.
Claim 10
Dependent Claim
54 words
The apparatus of claim 1 an overhead frame supported on said base; said standard being pivotally mounted on said base and being secured to said frame at its upper end; and means on said overhead frame for selectively positioning the upper end of said standard to select the angle of inclination of said standard.
Claim 11
Dependent Claim
51 words
The apparatus of claim 1 an overhead frame mounted on said base; rail means supported on said frame, disposed in parallel relation to said base and generally in the ring member support plane defined by said support and guide units; and a hoist supported on said rail for rectilinear movement therealong.
Claim 12
Dependent Claim
83 words
The apparatus of claim 1 said powered brush unit comprising a radial brush carried on its rotary motor shaft; a mounting plate for said powered brush units; said mounting plate carrying guide means for rectilinear movement of said motor carriage and extensible fluid motor coupled between said plate and said motor carriage and defining said means for selectively reciprocating said brush units; said mounting plate being adjustable relative to said base to orient said brush relative to the ring surface to be cleaned.
