Abstract
Abstract There is provided a compact apparatus for heating and setting hair, including a housing, a central wall in the housing defined by two spaced-apart panels, a plurality of elongated members passing through the central wall perpendicularly and extending to both sides thereof within the housing, and a flexible rope-like heating element between the two spaced-apart panels and wound around each of the elongated members, in order to provide heat thereto. The apparatus includes a number of hair-curling cylinders of conventional construction adapted to fit over the ends of the elongated members. By providing this construction, a single elongated member serves as two heating posts for two of the hair-curling cylinders, and the overall construction is relatively compact compared to prior devices. A reservoir for water is situated in the central wall, and heat from the heating element vaporizes the water to provide steam within the housing around the curling cylinders on the elongated members.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
A compact apparatus for heating and setting hair, comprising: a central wall defined by two spaced-apart panels, a plurality of heat-conductive elongated members, each passing through a separate pair of aligned apertures in said panels, and the free ends of each member extending away from the central wall in two opposing directions, a plurality of hair-curling cylinders each having a central axial passageway adapted to receive an end of one of said elongated members, a flexible rope-like heating element between the two spaced-apart panels and wound around each of the elongated members, wire means connected with said heating element, by which electrical energy can be conveyed to the heating element from an external source, said housing means enclosing the central wall, the elongate members, the heating element, and the cylinders when engaged with the elongated members.
Claim 2
Dependent Claim
136 words
A compact apparatus for heating and setting hair, comprising: a central wall defined by two spaced-apart panels, a plurality of heat-conductive elongated members, each passing through a separate pair of aligned apertures in said panels, and the free ends of each member extending away from the central wall in two opposing directions, a plurality of hair-curling cylinders each having a central axial passageway adapted to receive an end of one of said elongated members, a flexible rope-like heating element between the two spaced-apart panels and wound around each of the elongated members, wire means connected with said heating element, by which electrical energy can be conveyed to the heating element from an external source, said housing means enclosing the central wall, the elongate members, the heating element, and the cylinders when engaged with the elongated members.
Claim 3
Dependent Claim
16 words
The apparatus claimed in claim 1, in which the elongated members are hollow, open-ended, metallic tubes.
Claim 4
Dependent Claim
13 words
The apparatus claimed in claim 2, in which said tubes are of aluminum.
Claim 5
Dependent Claim
31 words
The apparatus claimed in claim 1, claim 2 or claim 3, in which each of the elongated members extends equally to both sides of the central wall and is perpendicular thereto.
Claim 6
Dependent Claim
49 words
The apparatus claimed in claim 1, claim 2 or claim 3, in which the housing means is adapted to rest upon any supporting surface in a given orientation, and in which the central wall, when the housing means is in said given orientation, is perpendicular to the supporting surface.
Claim 7
Dependent Claim
67 words
The apparatus claimed in claim 1, in which each of the elongated members extends equally to both sides of the cental wall and is perpendicular thereto, and in which the housing means is adapted to rest upon any supporting surface in a given orientation, the central wall being perpendicular to the supporting surface when the housing means is in said given orientation, and having a top edge.
Claim 8
Dependent Claim
84 words
The apparatus claimed in claim 1, claim 2 or claim 6, further including an upwardly open metallic reservoir for water located at an edge of said central wall which is uppermost when the housing means is in said given orientation, whereby heat generated by the heating element can rise and vaporize water in said reservoir, the apparatus being so constructed that water vapor from said reservoir can pass into those parts of the housing means which enclose the free ends of the elongated members.
Claim 9
Dependent Claim
131 words
The apparatus claimed in claim 1, claim 2 or claim 6, further including an upwardly open metallic reservoir for water located at an edge of said central wall which is uppermost when the housing means is in said given orientation, whereby heat generated by the heating element can rise and vaporize water in said reservoir, the apparatus being so constructed that water vapor from said reservoir can pass into those parts of the housing means which enclose the free ends of the elongated members, the housing means including an opening directly above the reservoir for allowing water to be added to said reservoir, and a closure member which can be moved manually between a position in which it closes the opening and a position in which it leaves the opening open.
Claim 10
Dependent Claim
47 words
The apparatus claimed in claim 1, claim 2 or claim 6, in which each of the two spaced-apart panels has flanged edge portions, the flanged edge portions of each panel extending toward the other panel, the peripheries of the edge portions of the panels being in juxtaposition.
Claim 11
Dependent Claim
95 words
The apparatus claimed in claim 6, in which each panel has a marginal flange directed perpendicularly to its main extent and projecting toward the other panel, the flange extending around the full periphery of the respective panel except for a part near said top edge of the panel, the apparatus including an upwardly open, metallic reservoir for water located along the top edge of the panels at said part where the flange is absent, whereby heat generated by the heating element can rise and vaporize water in said reservoir, the flanges having their edges juxtaposed.
