Carpet soil extracting wand having a powered brush
First Claim
1. A wand of a carpet soil extractor for cleaning carpets, said wand including a vacuum conduit connectable with a source of vacuum, a cleaning solution conduit connectable with a source of cleaning solution under pressure and electrical conductors connectable to a source of electric power, said wand comprising in combination:
- a. a chassis;
b. wheel means secured at one end of said chassis for aiding in the transport of said wand across the carpet to be cleaned;
c. said chassis including vacuum head means in fluid communication with the vacuum conduit for extracting a mixture of dirt and cleaning solution from the carpet, said vacuum head means including a snout bearing against the carpet and providing vertical support for said wand;
d. weight means for increasing the pressure of said snout acting upon the carpet to urge penetration of said snout into the nap of the carpet;
e. said chassis including nozzle means in fluid communication with the cleaning solution conduit for directing the cleaning solution into the carpet;
f. brush means for scrubbing the carpet wetted with the cleaning solution, said brush means including;
(1) a generally downwardly directed brush;
(2) an electric motor having a rotary output, said motor being electrically connected to the electrical conductors;
(3) linkage means interconnecting the rotary output and said brush for translating the motion of the rotary output to a reciprocal arcuate motion of said brush; and
(4) pivot means for pivotally supporting said linkage means and said brush with respect to said chassis; and
g. bias means disposed intermediate said chassis and said brush for urging said brush into continuing contact with the carpet.

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.

17. In a wand of a carpet soil extractor for scrubbing and vacuuming a carpet wetted with a cleaning solution, said wand including at least one wheel disposed at one end of the chassis of said wand for pivotally supporting said wand upon the carpet and a snout of a vacuum head disposed at the other end of the chassis for bearing against and vacuuming the carpet, the improvement comprising in combination:
-
a. brush means for scrubbing the wetted carpet; b. power means for providing a source of power; c. linkage means connecting said power means to said brush means for reciprocating said brush means through an arc having a horizontal pivot point; d. pivot means for pivotally supporting said linkage means and said brush means to accommodate vertical movement of said brush means with respect to the snout; and e. bias means for urging downward pivotal movement of said linkage means to bring said brush means into engagement with the carpet. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
