Patent ID: 7059014

Claim:
An apparatus for cleaning an interior surface of a tubular tool rail extending in a first longitudinal direction and including a slotted opening extending in the first longitudinal direction having a predetermined width normal to the first longitudinal direction, with the interior surface facing away from the slotted opening, the apparatus comprising: an elongated housing having a free end and a housing body extending in a second longitudinal direction, the housing body including a portion adjacent to the free end that has lateral dimensions small enough to allow rotation about an axis normal to the first longitudinal direction when the portion adjacent to the free end is located in the slotted opening; a brush extending laterally from the free end of the housing having a rotation axis that is generally normal to the second longitudinal direction, with the brush having a diameter that is less than the predetermined width of the slotted opening and a brush width such that a combined width including the brush width and the free end of the elongated housing is wider than the predetermined width of the slotted opening, and wherein the brush is contactable with the interior surface when the portion of the elongated housing adjacent to the free end is located in the slotted opening; a second brush extending laterally from the free end of the housing in opposed relation to the brush and rotatable about the rotation axis; and an air motor, drivable by a stream of air flow through the motor, operatively engaging the brush and the second brush to selectively cause rotation of the brush about the rotation axis.
