Abstract
Abstract A hair roller heating apparatus comprising, a plastic casing having a container section housing a heat conductive flat plate with straight, continuous, elongated, spaced, parallel rails extending upwardly from one side and a U-shaped heating element on the opposite side of the plate for heating the plate and rails. Hair rollers of various diameters each comprise an outer tubular cylindrical plastic member and an inner tubular cylindrical aluminum member fitting within the outer member in heat transfer relation therewith. Each of the inner and outer members have diametric recesses which fit on the rails with the inner member in heat transfer relation with the rails.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
181 words
Apparatus of the class described for heating hair, comprising: a. a hair roller having an outer substantially cylindrical hollow member with a bottom end, an interior surface means and an exterior surface b. two-spaced aligned, recesses extending longitudinally on opposite sides of the bottom end of the cylindrical member, c. an inner heat transmitting core element disposed within the cylindrical member in intimate contact with the interior surface means of the cylindrical member to transmit heat thereto, d. said core element having a bottom end and longitudinally extending recess means formed therein said recess means being aligned with said recesses, e. support means having raillike means for mounting said hair roller and having heating means for heating said raillike means, f. said raillike means when mounting said hair roller extending into said aligned recesses and said recess means and being in contact with said core element to conduct heat thereto, g. the shape and dimensions of the raillike means extending into said aligned recesses and recess means being a function of the configuration and dimensions of the recesses and recess means.
Claim 2
Dependent Claim
181 words
Apparatus of the class described for heating hair, comprising: a. a hair roller having an outer substantially cylindrical hollow member with a bottom end, an interior surface means and an exterior surface b. two-spaced aligned, recesses extending longitudinally on opposite sides of the bottom end of the cylindrical member, c. an inner heat transmitting core element disposed within the cylindrical member in intimate contact with the interior surface means of the cylindrical member to transmit heat thereto, d. said core element having a bottom end and longitudinally extending recess means formed therein said recess means being aligned with said recesses, e. support means having raillike means for mounting said hair roller and having heating means for heating said raillike means, f. said raillike means when mounting said hair roller extending into said aligned recesses and said recess means and being in contact with said core element to conduct heat thereto, g. the shape and dimensions of the raillike means extending into said aligned recesses and recess means being a function of the configuration and dimensions of the recesses and recess means.
Claim 3
Dependent Claim
64 words
The apparatus of claim 1 wherein said interior surface means of said cylindrical member is cylindrically shaped and the core element is tubular and cylindrically shaped and said recess means is two spaced aligned notchlike recesses on opposite sides of said core element and in alignment with said recesses of said cylindrical member and said raillike means extends through all of said aligned recesses.
Claim 4
Dependent Claim
27 words
The apparatus of claim 2 wherein said recesses are diametrically aligned across the bottom ends and extend longitudinally of said outer cylindrical member and said core element.
Claim 5
Dependent Claim
33 words
The apparatus of claim 1 wherein said support means is a flat plate with said raillike means extending upwardly from the plate and said heating means is a heating element on said plate.
Claim 6
Dependent Claim
37 words
The apparatus of claim 4 wherein the core contact is an inner hollow cylindrical member concentrically disposed with respect to the outer cylindrical member and means are provided on both cylindrical members to restrain relative movement therebetween.
Claim 7
Dependent Claim
27 words
The apparatus of claim 5 wherein the raillike means is of tapered inverted U-shaped configuration in cross section and the recesses and recess means are similarly configurated.
Claim 8
Dependent Claim
155 words
Apparatus of the class described for heating hair, comprising in combination, a. a casing, b. a flat plate in the casing and including heating means for heating the plate, c. a plurality of tubular hair rollers of various diameters each having a pair of identically sized and shaped diametrically opposite recesses at one end to form a groove, said rollers adapted to be positioned onto the heating plate with the axes thereof normal to the surface of the plate, d. a plurality of spaced and parallel raillike members carried and heated by the heating plate, said raillike members being elongated for holding a plurality of rollers and being of identical size and shape and identical in size and shape to said recesses for fitting within the recesses to mount the hair rollers on the heating plate, e. the spacing between raillike members being dependent upon the radii of the hair rollers mounted on adjacent rails.
Claim 9
Dependent Claim
155 words
