Abstract
Abstract A styling apparatus for treating hair with heat includes a tubular heated mandrel around which hair is wound to be heat treated and rows of bristles extending from the mandrel for tensioning the hair while the hair is wound. The bristles are preferably mounted on a removable attachment which is received in a slot extending along the mandrel. A row of teeth may also extend from the attachment so that the hair may be combed prior or subsequent to heat treatment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
Apparatus for treating hair, comprising: a mandrel having first and second ends, a cavity extending therein and a heat treating surface; handle means secured to the first end of the mandrel; mounting means disposed along the periphery of the mandrel; attachment means detachably retained by said mounting means, said attachment means including a base having a row of spaced relatively rigid teeth extending therefrom, and first and second rows of bristle tufts extending along each side of the row of teeth in spaced relation thereto, wherein the tufts of the first row are aligned with every other space between the teeth, and the tufts of the second row are aligned with the alternate spaces between the teeth not having a tuft of the first row aligned therewith; and heating means for supplying heat to the surface of the mandrel to heat treat, said heating means being disposed within said cavity of said mandrel.
Claim 2
Dependent Claim
153 words
Apparatus for treating hair, comprising: a mandrel having first and second ends, a cavity extending therein and a heat treating surface; handle means secured to the first end of the mandrel; mounting means disposed along the periphery of the mandrel; attachment means detachably retained by said mounting means, said attachment means including a base having a row of spaced relatively rigid teeth extending therefrom, and first and second rows of bristle tufts extending along each side of the row of teeth in spaced relation thereto, wherein the tufts of the first row are aligned with every other space between the teeth, and the tufts of the second row are aligned with the alternate spaces between the teeth not having a tuft of the first row aligned therewith; and heating means for supplying heat to the surface of the mandrel to heat treat, said heating means being disposed within said cavity of said mandrel.
Claim 3
Dependent Claim
49 words
The hair treating apparatus of claim 1, wherein said mounting means includes: a slot extending along said mandrel, wherein said slot is defined by spaced flanges beneath which said base is received and from which said teeth and projections extend when said attachment means is mounted on said mandrel.
Claim 4
Dependent Claim
43 words
The apparatus of claim 2, wherein said slot means terminates adjacent the second end of said mandrel and wherein cap means overlies the second end of said mandrel and selectively overlies said slot to retain said attachment means selectively in said slot means.
Claim 5
Dependent Claim
43 words
The apparatus of claim 3, wherein the cap means is rotatably mounted and has an eccentric configuration so that when rotated, said cap means selectively overlies and clears said slot to allow said attachment to be secured to and removed from said mandrel.
Claim 6
Dependent Claim
54 words
The apparatus of claim 1, wherein the row of teeth projects radially with respect to said mandrel and wherein the bristles project obliquely with respect to said teeth so that when the apparatus is oriented so that the bristles engage the hair, the hair will be tensioned across the heated surface of the mandrel.
Claim 7
Dependent Claim
144 words
A hand-held apparatus for treating hair, including: a tubular mandrel of metallic material having a hair treating surface theron, said mandrel having an eccentric configuration relative to a longitudinal axis and having a thickness which increases from one side thereof to the other; a slot extending longitudinally in the thickest portion of the mandrel to define a female portion of a dove-tail mounting; a hair engaging attachment devetailed in said slot, said hair engaging attachment including one row of teeth and two rows of bristles projecting obliquely, with respect to said teeth and disposed on opposite sides of the row of teeth for tensioning hair as the bristles are applied against the hair; and means within said mandrel for heating said mandrel so that hair tensioned by said bristles and urged aginst the surface of said mandrel is heat treated to form waves therein.
Claim 8
Dependent Claim
144 words
A hand-held apparatus for treating hair, including: a tubular mandrel of metallic material having a hair treating surface theron, said mandrel having an eccentric configuration relative to a longitudinal axis and having a thickness which increases from one side thereof to the other; a slot extending longitudinally in the thickest portion of the mandrel to define a female portion of a dove-tail mounting; a hair engaging attachment devetailed in said slot, said hair engaging attachment including one row of teeth and two rows of bristles projecting obliquely, with respect to said teeth and disposed on opposite sides of the row of teeth for tensioning hair as the bristles are applied against the hair; and means within said mandrel for heating said mandrel so that hair tensioned by said bristles and urged aginst the surface of said mandrel is heat treated to form waves therein.
Claim 9
Dependent Claim
31 words
The apparatus of claim 6, wherein the mandrel has a handle projecting from one end and a locking cap for holding the attachment in the slot extending from the other end.
