An apparatus having utility for cleaning large, non-horizontal surfaces such as walls. A generally planar head is adapted to be oriented in a generally vertical manner during use, such that it will have a top, bottom, two sides, and front and rear surfaces. A fibrous pad is sized to cover a substantial portion of the front surface of the head. The pad is selectively removable from the head; but during use the pad is firmly held against the friction forces that are imposed on it by moving the head across the surface being cleaned. A plurality of reservoirs, a conduit, and a pump are provided for supplying a selected cleaning or rinsing liquid at a controlled rate to the top of the head. A low-pressure chamber adjacent the rear of the head is used to collect arty liquid that: has passed through the fibrous pad. A resilient seal around the sides and the bottom of the head is effective to inhibit the leakage of liquid from around the boundaries of the head for as long as the head is maintained upright and as long as a pressure lower than atmospheric is maintained in the chamber. An elongated handle is used by an operator to support the head during cleaning. An open-top tub with supporting casters is used to support and transport the apparatus at a job site.

Washing apparatus for walls and other non-horizontal surfaces

A portable apparatus adapted for use in filling chuck holes in paved surfaces with a sulphur-based material that has been heated to a plasticized condition. The apparatus includes an electrically heated furnace in which an auger is mounted for the purpose of moving a sulphur-based material through the furnace at a controlled rate (e.g., about 2 feet per minute), such that the material will be elevated to a temperature of above 305 degrees Farenheit (the melting point of sulphur) to produce a tenacious filler material. The furnace is heated by tubular resistance heaters that are bent in a spiral fashion around a mandrel, so that they may be placed in intimate contact with the exterior of a tube which constitutes the core of the furnace. The furnace is fed by a hopper that is mounted above the entry point for the auger, so that dry material may be fed--by gravity--into the furnace whenever a gate-valve mechanism is opened. The furnace and its hopper are relatively light weight, typically weighing only about 360 pounds, and are readily moved about by one person when supporting wheels are installed on the bottom of a frame that supports the furnace. A tandem-axle trailer provides an optimum way of transporting the furnace and the ancillary materials and equipment that are used with the furnace, e.g., a portable generator, a small air compressor, bags of the hole-filling material, etc.
