Filed:

Oct 4, 1977

Appl. No.:

5/839301

Inventors:

Patrick E. Lynch - Phoenix AZ

Assignee:

Chemko Industries, Inc. - Phoenix AZ

International Classification:

A47L 700

US Classification:

15320

Abstract:

A self contained compact carpet soil extractor includes a vacuum tube for singularly supporting a vacuum head, nozzles through which the cleaning solution is dispensed, a pivotally mounted powered brush and motor means for driving the brush; additionally, the source of vacuum, a supply of cleaning solution under pressure and a waste tank are directly or indirectly suspended from the vacuum tube. One variant includes means for supporting a quantity of the cleaning solution upon the vacuum tube and a further variant relies upon external sources to provide vacuum and cleaning solution. Support upon the carpet for the extractor is provided by the mouth of the vacuum head, the brush and a curved spring skid; the force exerted by the brush and the depth to which the brush extends into the carpet nap is primarily a function of the bristle length with respect to the plane defined by the vacuum head mouth and the skid.

Abstract:

In a carpet soil extracting wand having nozzles for dispensing a cleaning solution and a vacuum head for extracting the mixture of dirt and cleaning solution, a powered brush reciprocally travels through a predetermined arc to scrub the carpet. Bias means are included to allow variation in the pressure exerted by the reciprocating brush upon the pile of the carpet. For manually operated carpet soil extractors, the handle is pivotally positionable for ease of use while the interconnecting conduits to sources of vacuum and cleaning solution are maintained rigid.
