Abstract
Abstract A moistened fabric pad is supported in a container having a cover configured to engage a type element. The cover is fastened to the container so that the fabric pad and type element are brought into contact. Rotation of the type element against the surface of the moistened fabric pad removes dirt and ink from all areas of the type element.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A type element cleaner for a generally flat type element having a hub, a plurality of radial support arms, and a plurality of print characters respectively disposed on the support arms, the type element cleaner comprising: a cleaning element having a generally planar cleaning surface; a container having a generally flat bottom and a recessed portion centrally disposed at the bottom for receiving the type element hub, wherein the cleaning element is positioned on the bottom of the container; and a support shaft, rotatably connected to the container and oriented generally perpendicular to the container bottom, adapted to support the type element so that axial force on the shaft presses the type element against the cleaning element to cooperatively engage the type element print characters in a facing relationship with the cleaning element cleaning surface and rotation of the shaft provides relative movement between the type element and the cleaning element, wherein ink and contaminants are removed from the type element.
Claim 2
Dependent Claim
161 words
A type element cleaner for a generally flat type element having a hub, a plurality of radial support arms, and a plurality of print characters respectively disposed on the support arms, the type element cleaner comprising: a cleaning element having a generally planar cleaning surface; a container having a generally flat bottom and a recessed portion centrally disposed at the bottom for receiving the type element hub, wherein the cleaning element is positioned on the bottom of the container; and a support shaft, rotatably connected to the container and oriented generally perpendicular to the container bottom, adapted to support the type element so that axial force on the shaft presses the type element against the cleaning element to cooperatively engage the type element print characters in a facing relationship with the cleaning element cleaning surface and rotation of the shaft provides relative movement between the type element and the cleaning element, wherein ink and contaminants are removed from the type element.
Claim 3
Dependent Claim
28 words
The type element cleaner of claim 1 wherein the support shaft is moveable with respect to the container in a direction along a longitudinal axis of the shaft.
Claim 4
Dependent Claim
30 words
The type element cleaner of claim 1 including a cleaning fluid applied to the cleaning element in an amount not greater than the amount necessary to saturate the cleaning element.
Claim 5
Dependent Claim
17 words
The type element cleaner of claim 1 wherein said cleaning element is removably disposed in said container.
Claim 6
Dependent Claim
15 words
The type element cleaner of claim 1 wherein said cleaning element is a fabric pad.
Claim 7
Dependent Claim
154 words
A type element cleaner for a generally spherical type element having print characters disposed about an exterior surface, said type element cleaner comprising: a container having a bottom with a concave indentation shaped to substantially conform to the curvature of the type element; a cleaning element mounted in said indentation and shaped to substantially conform to the curvature of the type element; a cover pivotally connected to the container; a support shaft rotatably coupled to the cover and adapted to support the type element so that closure of the cover causes axial force on the shaft to press a portion of the type element against the cleaning element so as to cooperatively engage a plurality of the type element print characters in a facing relationship with the cleaning element and rotation of the shaft provides relative movement between the type element and cleaning element, wherein ink and contaminants are removed from the type element.
Claim 8
Dependent Claim
154 words
A type element cleaner for a generally spherical type element having print characters disposed about an exterior surface, said type element cleaner comprising: a container having a bottom with a concave indentation shaped to substantially conform to the curvature of the type element; a cleaning element mounted in said indentation and shaped to substantially conform to the curvature of the type element; a cover pivotally connected to the container; a support shaft rotatably coupled to the cover and adapted to support the type element so that closure of the cover causes axial force on the shaft to press a portion of the type element against the cleaning element so as to cooperatively engage a plurality of the type element print characters in a facing relationship with the cleaning element and rotation of the shaft provides relative movement between the type element and cleaning element, wherein ink and contaminants are removed from the type element.
Claim 9
Dependent Claim
28 words
The type element cleaner of claim 6 wherein the support shaft is movable with respect to the cover in a direction along a longitudinal axis of the shaft.
Claim 10
Dependent Claim
30 words
The type element cleaner of claim 6 including a cleaning fluid applied to the cleaning element in an amount not greater than the amount necessary to saturate the cleaning element.
Claim 11
Dependent Claim
18 words
The type element cleaner of claim 6 wherein said cleaning element is removably disposed in said container indentation.
Claim 12
Dependent Claim
15 words
The type element cleaner of claim 6 wherein said cleaning element is a fabric pad.
