Abstract

An elongated tubular handle and support member connectable at its upper end with a vacuum hose and at its lower end with a vacuum head having a perpendicularly extending, elongated suction opening and including a pair of spray nozzles fixed with respect to the vacuum head and adapted to spray, respectively and selectively, either carpet cleaning fluid or carpet dyeing fluid behind the vacuum head, supports along the length thereof an open-topped container for removably receiving a liquid dye container. The tubular handle and support member also has attached thereto a control valve assembly for directing fluid under pressure to either of said spray nozzles, selectively, from a single remote source. The means supplying pressurized fluid to one of the spray nozzles includes a flexible conduit series-connected in which is a venturi member having a venturi orifice communicating through a control valve with the dye container for withdrawing dye into the flow path of the pressurized fluid supply to the dye spraying nozzle.

Claims

1. Carpet cleaning and dyeing apparatus comprising, in combination, an elongated tubular handle and support member, a hollow, flared vacuum head member fixed with respect to and communicating with the interior of one end of said tubular handle and support member, said vacuum head member terminating in a narrow, elongated opening extending substantially perpendicularly with respect to longitudinal axis of said elongated tubular handle and support member, first and second spray nozzles secured with respect to said vacuum head member and having elongated spray orifices adapted to spray fluid in fan-shaped configuration and in laterally spaced relation with respect to said flared vacuum head member elongated opening, means for supplying pressurized fluid, selectively, to one of said spray nozzles for carpet cleaning, means for supplying pressurized carpet dyeing solution, selectively, to the other of said spray nozzles, valve means supported on said elongated tubular handle and support member for manual control of pressurized fluid selectively supplied to said spray nozzles, said means for supplying pressurized fluid to said one of saidspray nozzles comprising a first conduit means communicating between said valve means and said one of said spray nozzles, said means for supplying pressurized carpet dye solution to said other of said spray nozzles comprising a second conduit means communicating between said valve means and said other of said spray nozzles, a dye container, a housing member supported on said tubular handle and support member, said dye container being receivable in said housing member, flexible conduit means communicating between said dye container and said second conduit means, and a venturi opening member at the juncture of said flexible conduit means with said second conduit means for withdrawing dye from said dye container into the fluid flow path of said second conduit means.

2. Carpet cleaning and dyeing apparatus as defined in claim 1, wherein said dye container is fabricated of a flexible plastic material so as to collapse as fluid dye is withdrawn therefrom.

3. Carpet cleaning and dyeing apparatus as defined in claim 2, wherein said flexible conduit means communicating said dye container and said second conduit means comprises a hollow needle removably insertable in said flexible container.

4. Carpet cleaning and dyeing apparatus as defined in claim 1, wherein said dye container is substantially rigid and bottle-shaped, said bottle-shaped container having a screw-on cap, and air vent means in said cap, said flexible conduit means extending through said cap.

5. Carpet cleaning and dyeing apparatus as defined in claim 1, including means for smoothening fluid flow pressure pulsations in said second conduit means.

6. Carpet cleaning and dyeing apparatus as defined in claim 5, wherein said pressure pulsations smoothening means comprises a pressure-reducing member connected in said second conduit means in bypassing relation with respect to the juncture of said flexible conduit means with said second conduit means.

7. Carpet cleaning and dyeing apparatus as defined in claim 1, including an adjustable flow metering valve in said flexible conduit means.
