Abstract
Abstract A shampooer for nap surfaces which supplies shampoo in liquid form to an elongated distributor. A rigid noncellular strip is mounted directly below the distributor, and a resilient sponge is secured to the strip. A brush is reciprocatingly driven into beating squeezing engagement with the sponge to turn the liquid into foam. The brush then carries the foam away from the sponge, deposits it on the carpet and works it in.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
94 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liquid distributor, b. means to supply liquid shampoo to said distributor, c. a sponge disposed below said distributor for receiving liquid from said distributor, d. and means to alternately engage and disengage from said sponge to squeezingly beat said sponge at a substantial frequency to cause foam to be generated from the liquid in said sponge, e. said last-named means also serving as means to work the generated foam into the nap surface.
Claim 2
Dependent Claim
94 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liquid distributor, b. means to supply liquid shampoo to said distributor, c. a sponge disposed below said distributor for receiving liquid from said distributor, d. and means to alternately engage and disengage from said sponge to squeezingly beat said sponge at a substantial frequency to cause foam to be generated from the liquid in said sponge, e. said last-named means also serving as means to work the generated foam into the nap surface.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein said beating means (d) also comprises means for carrying generated foam from said sponge to the nap surface.
Claim 4
Dependent Claim
11 words
to carry generated foam from said sponge to the nap surface,
Claim 5
Dependent Claim
11 words
to carry generated foam from said sponge to the nap surface,
Claim 6
Dependent Claim
50 words
and a relatively rigid elongated backing for said sponge, d. and means to alternately engage and disengage from said sponge to squeezingly beat said sponge at a substantial frequency and confine it against said backing during said engagement to cause foam to be generated from the liquid in said sponge.
Claim 7
Dependent Claim
50 words
and a relatively rigid elongated backing for said sponge, d. and means to alternately engage and disengage from said sponge to squeezingly beat said sponge at a substantial frequency and confine it against said backing during said engagement to cause foam to be generated from the liquid in said sponge.
Claim 8
Dependent Claim
9 words
and to subsequently work the foam into the surface.
Claim 9
Dependent Claim
9 words
and to subsequently work the foam into the surface.
Claim 10
Dependent Claim
44 words
The device of claim 1 wherein said beating means (d) comprises: a. a brush backing disposed adjacent said sponge, b. a brush anchored in said backing, c. and means to oscillate said backing to thereby reciprocate said brush into squeezing engagement with said sponge.
Claim 11
Dependent Claim
71 words
The device of claim 1 wherein said beating means (d) comprises: a. a brush backing disposed adjacent said sponge, b. a brush having flexible bristles anchored in said backing so that the bristle tufts are progressively more flexible downwardly from said backing, c. and means to oscillate said backing to thereby reciprocate said brush into squeezing engagement with said sponge whereby the squeezing action is progressively greater downwardly along said sponge.
Claim 12
Dependent Claim
40 words
In the device of claim 1: a. a noncellular backing for said sponge, b. said backing having an upper surface disposed directly beneath said distributor for receiving liquid shampoo therefrom, c. said backing surface being inclined downwardly toward said sponge.
Claim 13
Dependent Claim
49 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. an elongated liquid distributor, b. means to supply liquid shampoo to said distributor, c. a fixed sponge assembly disposed below said distributor for receiving liquid therefrom, said assembly including:
Claim 14
Dependent Claim
49 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. an elongated liquid distributor, b. means to supply liquid shampoo to said distributor, c. a fixed sponge assembly disposed below said distributor for receiving liquid therefrom, said assembly including:
Claim 15
Dependent Claim
49 words
The device of claim 6 wherein said beating means (d) comprises: a. a brush backing disposed adjacent said sponge, b. a brush anchored in said brush backing, c. and means to oscillate said brush backing to thereby reciprocate said brush into and out of squeezing engagement with said sponge.
Claim 16
Dependent Claim
39 words
The device of claim 6: a. in which said sponge backing has an upper surface disposed directly beneath said distributor for receiving liquid therefrom, b. said sponge backing surface being inclined downwardly toward said sponge to spread liquid thereover.
Claim 17
Dependent Claim
63 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liquid distributor, b. means to supply liquid shampoo to said distributor, c. a sponge disposed below said distributor for receiving liquid from said distributor, c. a sponge disposed below said distributor for receiving liquid from said distributor, d. and flexible brush means:
Claim 18
Dependent Claim
63 words
In a device for applying liquid shampoo in the form of foam to a nap surface, the combination comprising: a. a liquid distributor, b. means to supply liquid shampoo to said distributor, c. a sponge disposed below said distributor for receiving liquid from said distributor, c. a sponge disposed below said distributor for receiving liquid from said distributor, d. and flexible brush means:
