  • Patent number: 8555461
    Abstract: The device for cleaning grooved surfaces of a moving transport, such as escalators and moving walkways, includes a frame supporting at least one vacuum pump and a plurality of vacuum heads and a plurality of brush heads. A carriage is attached relative to the frame to which at least one of the plurality of vacuum heads and brush heads are slidably attached. The carriage can be attached to the frame in a multitude of ways, including utilizing a four-bar linkage. The carriage is positionable between a stored position and a deployed position. Additionally, the carriage can be angularly adjustable to align with a horizontal plane of the grooved surface. A handle can be pivotably attached to the frame wherein pivotable movement of the handle is mechanically coupled to movement of the carriage between the stored and deployable positions.

  • Patent number: 4083077
    Abstract: A hand tool is constructed for detachable connection to a fluid cleaning machine such as a steam cleaning unit. A hollow head has convexly rounded front and rear edges to promote smooth back and forth sliding motion over fabric. Forward and rearward regions of the head constitute a suction chamber and a spray chamber respectively. A fluid solution line is surrounded and protected by a flexible suction hose that is releasably coupled to a neck of the hand tool. A flow control interconnects the fluid solution line and a spray nozzle in the spray chamber. Baffles positioned across a lower opening of the suction chamber reduce wrinkling and ridging tendencies of the fabric as it is being cleaned.
