Carpet soil extractor having a powered brush
First Claim
1. A manually propelled carpet soil extractor for cleaning carpets and operable in conjunction with a source of vacuum and a source of cleaning solution under pressure, said carpet soil extractor comprising in combination:
- a. a vacuum tube connected to said source of vacuum, said vacuum tube having a lower end for drawing waste water from the carpet;
b. a vacuum head attached to the lower end of said vacuum tube for vacuuming the carpet, said vacuum head including a mouth;
c. a brush for scrubbing the carpet, said brush being in general longitudinal alignment with the longitudinal axis of said mouth;
d. a pivotally depending linkage assembly suspended from the lower end of said vacuum tube for supporting said brush and imparting a reciprocating arcuate motion to said brush;
e. a motor for reciprocally pivoting said linkage assembly, said motor including a rotating output shaft, a casing and means for attaching said casing to said vacuum tube;
f. means for translating the rotary motion of said output shaft into reciprocating pivotal motion of said linkage assembly;
g. a curved spring skid for supporting, in conjunction with said vacuum head, said carpet soil extractor upon the carpet;
h. a plate secured to said casing of said motor for supporting said spring skid; and
i. a nozzle assembly secured to said plate and in fluid communication with said source of cleaning fluid under pressure for spraying the carpet with cleaning solution.

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.
