Abstract: Floor polishing machines include a motor housing, mounted vertically above the base of the machine that contains and protects the motor of the machine. A drip cover that may have a convex shape is mounted on the top of the motor housing and offset from the housing to provide a space between the housing and the cover through which air can flow to cool the motor during operation of the polishing machine. The drip cover has a cylindrical skirt that extends axially from the drip cover to surround the upper portion of the motor housing. Formed concentrically with the skirt, on the inner surface of the drip cover is a cup sized to accept, hold and protect the upper bearing of the motor. The drip cover further includes a downwardly facing electrical inlet or plug attached to the inner surface of the cover within the cylindrical skirt.

Abstract: Apparatus for treating a floor surface has a drive motor with a drive shaft rotatable on a rotation axis, and, a drive assembly drivingly connected to the drive shaft for conjoint rotation therewith. A floor surface treatment device is releasably connected to the drive assembly for conjoint rotation therewith about the rotation axis of the drive shaft. The floor surface treatment device is adapted for engagement with the floor surface to treat the floor surface upon rotation off the device relative to the floor surface. In a preferred embodiment, the drive assembly has a set of gear teeth and the floor surface treatment device has a corresponding set of gear teeth and is sized relative to the drive assembly to permit driving interengagement of the drive assembly gear teeth with the gear teeth of the floor surface treatment device.

Abstract: An indicator junction module for connecting the electrical components of a pressure washer for dispensing a cleaning fluid under pressure. The indicator junction module includes terminal connectors for receiving leads from the components and indicator circuits corresponding to the components. At least one of the indicator circuits has one of its terminals electrically connected to an indicator device and the other of its terminals electrically connected to another indicator circuit. Each indicator device provides a visual indication of a condition of the corresponding component. The indicator junction module also includes an enclosure for enclosing the indicator circuits wherein the indicator devices are visible from outside the enclosure to an operator of the pressure washer and a portion of each terminal connector is external to the enclosure.
