Abstract
Abstract An implement for cleaning, massaging and grooming of the hair and scalp using a plurality of rows of tapered teeth. The teeth in cross-section have a sharply cutoff base portion which cooperates with the tapered sides of the teeth to produce a cleaning action on hair drawn over the teeth, and cause the foreign material on the hair and scalp to be deposited on the base portions of the teeth. The foreign material is removed from the instrument by drawing a flat tool across the base portions of the teeth in each row. The teeth are inclined from the perpendicular to the body of the implement to cause the hair to be drawn into the implement as it is utilized. Adjacent rows of teeth are staggered and spaced by at least one tooth width to increase the cleaning action.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
An implement for removing dirt and other foreign materials from hair without the use of chemicals, wherein said implement may be drawn through the hair without excessive pulling of the hair, and said implement has provision for facilitating the removal of accumulated foreign material, and wherein the improvement comprises: a plurality of elongated teeth extending out of the body of said implement, the longitudinal axes of said teeth being in substantial parallelism, said teeth being spaced along at least three spaced rows, said teeth in cross section, each having tapered sides and a base portion, said base portion of said teeth having material removal surface means at substantially a right angle to the long axis of said cross section for increasing the tendency of said teeth to strip material from said hair strands passing over said teeth, said base portions of said teeth being oriented in the same direction, whereby the implement may be drawn through the hair and the dirt and other foreign material on the hair removed by the action of the hair passing over said tapered sides of said teeth, and past said base portions.
Claim 2
Dependent Claim
188 words
An implement for removing dirt and other foreign materials from hair without the use of chemicals, wherein said implement may be drawn through the hair without excessive pulling of the hair, and said implement has provision for facilitating the removal of accumulated foreign material, and wherein the improvement comprises: a plurality of elongated teeth extending out of the body of said implement, the longitudinal axes of said teeth being in substantial parallelism, said teeth being spaced along at least three spaced rows, said teeth in cross section, each having tapered sides and a base portion, said base portion of said teeth having material removal surface means at substantially a right angle to the long axis of said cross section for increasing the tendency of said teeth to strip material from said hair strands passing over said teeth, said base portions of said teeth being oriented in the same direction, whereby the implement may be drawn through the hair and the dirt and other foreign material on the hair removed by the action of the hair passing over said tapered sides of said teeth, and past said base portions.
Claim 3
Dependent Claim
27 words
The hair cleaning implement of claim 1, wherein, said rows of teeth are spaced by a distance in excess of the long axis dimension of said teeth.
Claim 4
Dependent Claim
29 words
The hair cleaning implement of claim 1, wherein: the individual teeth in a row of teeth are staggered in relationship to the individual teeth in adjacent rows of teeth.
Claim 5
Dependent Claim
23 words
The hair cleaning implement of claim 1, wherein: said teeth are inclined from a line normal to said body portion by approximately 30*.
Claim 6
Dependent Claim
28 words
The hair cleaning implement of claim 4, wherein the outmost surfaces of said inclined teeth are cutoff in a plane parallel to the plane of said body portion.
Claim 7
Dependent Claim
34 words
The hair cleaning implement of claim 1, wherein the base portions of said teeth are substantially planar said planar base portions on the teeth in a row of teeth lie in the same plane.
Claim 8
Dependent Claim
14 words
The hair cleaning implement of claim 1, wherein said teeth are comprised of polypropylene.
