Abstract

The invention is concerned with a carpet cleaning implement useful for continuously washing and rinsing a floor fastened carpet in a single operation. The implement includes a head adapted to be rolled along on a carpet upon wheels. The head includes adjacent its bottom a first row of jets for delivering a flow of a solution of a washing composition such as rug shampoo, under pressure, into the carpet. An oscillatory brush is provided near to the first row of jets for vigorously agitating the solution into the carpet. A second row of jets are located near the brush on its other side. The second row of jets serves to deliver a flow of rinse water under pressure into the carpet. Next to the second row of jets is a channel which communicates with a vacuum source of at least about 100 inches of water for picking up the combined solution and rinse water as the head is rolled along the carpet in a direction whereby the first row of jets passes over a portion of the carpet followed sequentially by the brush, the second row of jets and the channel. A handle is provided extending from the head whereby an operator can direct and control the motion of the head over the carpet. A valve is provided on the handle in easy position for operator control. The valve communicates with a liquid source and serves to simultaneously control flow of the solution through the first row of jets and of the rinse water through the second row of jets.

Claims

1. A carpet cleaning implement useful for continuously washing and rinsing a floor fastened carpet in a single operation, comprising:

a head having a cover thereover, said head being adapted to be rolled along on said carpet upon roller means located adjacent a first end thereof, a bottom portion of said head facing said carpet, said head including adjacent to said bottom portion thereof first liquid delivery means for delivering a flow of a first liquid under pressure onto said carpet, a brush adjacent said first liquid delivery means for agitating said first liquid into said carpet, second liquid delivery means adjacent said brush and on an opposite side therefrom from said first liquid delivery means for delivering a flow of a second liquid under pressure into said carpet and a channel adjacent a second end of said head communicating with a vacuum source of at least about 100 inches of water, said channel being adjacent said second liquid delivery means and on an opposite side therefrom from said brush, said channel serving for picking up said first liquid and said second liquid as said head is rolled along said carpet in a direction whereby said first liquid delivery means first passes a portion of said carpet followed sequentially by said brush, said second delivery means and said channel;

motor means drivingly communicating with said brush to supply oscillatory forwards and backwards motion thereto alternately towards and away from said first and second ends of said head respectively;

a handle extending from said first end of said head for operator control thereof, said motor means, head, first and second liquid delivery means, channel and handle being located so that said roller means supports the great majority of the weight of said implement, said head being normally rolled along said carpet by exertion of a pulling force on said handle;

valve means on said handle communicating with a liquid source for controlling flow of said first liquid through said first liquid delivering means and of said second liquid through said second liquid delivering means.

2. An implement as in claim 1, wherein said first liquid comprises water and said second liquid comprises a water based rinse and including a reservoir for a liquid cleaner concentrate;

a first conduit communicating said valve means and said first liquid delivery means and means for introducing said concentrate into said first conduit as said first liquid flows therethrough to thereby form a cleaner composition.

3. An implement as in claim 2, wherein said introducing means comprises a venturi injector whereby the amount of said concentrate introduced is generally proportional to the rate of flow of said first liquid through said first conduit.

4. An implement as in claim 3, including a valve intermediate said reservoir and said first conduit which valve can be used for metering said concentrate and can be shut off thereby causing only said first liquid to be delivered by said first liquid delivery means.

5. An implement as in claim 4, including a liquid delivery conduit intermediate said valve means and said first conduit and a second conduit branching off from said liquid delivery conduit and leading to said second liquid delivery means.

6. An implement as in claim 5, wherein said first liquid delivery means comprises a first plurality of openings arranged in a generally straight line and said second delivery means comprises a second plurality of openings generally parallel to said first plurality of openings.

7. An implement as in claim 6, wherein said handle is mounted to said head so as to be rotatable in a plane perpendicular to said carpet and including means for fastening said handle at a selectable angle from said carpet to provide adjustment for operators of different heights.

8. An implement as in claim 7, wherein said channel defines a generally straight line which is generally parallel to said first and second pluralities of openings and said brush.

9. An implement as in claim 8, wherein said implement includes only one brush.

10. An implement as in claim 9, wherein said motor means includes a shaft and including;

rod means pivotally and eccentrically attached at a first end thereof to said shaft and pivotally attached at a second end thereof to an extension of said brush at a position removed from said brush; and

means pivotally mounting said extension to said head intermediate said brush and said pivotal attachment of said extension to said second end of said rod means.
