Abstract
Abstract A circular pan-like base is fitted with a rotatable imperforate support tray on which hair curling rollers can be deposited in upended position. Electric heat means at the bottom of the base operates to boil water causing steam to arise around the tray. The top of the base is covered by a hinged cover having an inside pattern of radial striations for collecting and guiding condensate back toward the periphery of the unit where it can drain by gravity back into the water below the tray. A dispensing chamber for hair conditioning composition is located on the tray and the tray is provided with drain passages for carrying condensate and conditioning medium deposited on the tray to the rim for discharge into the water below. Steam venting means and liquid level control means both designed to inhibit collection of condensate on the exterior of the unit are provided.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
Apparatus for heating and conditioning hair curling rollers comprising a closed vessel having a pan-like base and a cover for the base, an imperforate roller support tray disposed within said base and spaced above the inside bottom thereof, said tray having an outline in plan similar to the inside horizontal cross sectional outline of the base with the periphery of the tray close to but spaced slightly from said inside wall, electrical means located beneath said tray adjacent the inside bottom of said bAse for heating water in the base by applying potential to the water between a pair of immersed electrodes, the upper surface of said tray provided with drainage channels radiating outwardly from the central portion thereof for returning condensate to the periphery of said tray, said tray including a plurality of upstanding rings forming annular channels on said tray, said rings interrupted at said drainage channels to permit flow of condensate past the rings.
Claim 2
Dependent Claim
157 words
Apparatus for heating and conditioning hair curling rollers comprising a closed vessel having a pan-like base and a cover for the base, an imperforate roller support tray disposed within said base and spaced above the inside bottom thereof, said tray having an outline in plan similar to the inside horizontal cross sectional outline of the base with the periphery of the tray close to but spaced slightly from said inside wall, electrical means located beneath said tray adjacent the inside bottom of said bAse for heating water in the base by applying potential to the water between a pair of immersed electrodes, the upper surface of said tray provided with drainage channels radiating outwardly from the central portion thereof for returning condensate to the periphery of said tray, said tray including a plurality of upstanding rings forming annular channels on said tray, said rings interrupted at said drainage channels to permit flow of condensate past the rings.
Claim 3
Dependent Claim
29 words
Apparatus as in claim 1, said cover including on its inside surface a plurality of alternating radial ridges and grooves inclined downwardly from the center toward the rim thereof.
Claim 4
Dependent Claim
71 words
Apparatus as in claim 1, including a standpipe projecting upwardly from the inside bottom of said base and having a vertical passageway therethrough continuing through the bottom of the base and providing a water level control means, and buoyant cap means normally covering said pipe but floatable to an uncovering position in the event of increase in the level of water to a level above the upper end of said standpipe.
Claim 5
Dependent Claim
25 words
Apparatus as in claim 3, said cap having a small perforation therethrough permitting limited steam flow through said cap into and out of said passageway.
Claim 6
Dependent Claim
71 words
Apparatus as in claim 1, said base having an opening through the side wall thereof near the upper edge, and a baffle plate on the exterior of said base partially screening said opening and forming a water trap on the exterior of said base, said base further including drain channels communicating between said trap and the interior of said base for drainage of water from said trap back into the base.
Claim 7
Dependent Claim
82 words
Apparatus as in claim 1, including a member supported on said tray having a cup-like chamber therein for receiving and storing a hair conditioning composition, said member comprising an upstanding tube having its lower end adjacent the central portion of the tray and having the receptacle recessed in the upper end thereof, said receptacle having a perforation in its bottom and means between the lower end of the member and the tray providing passageways between the inside and outside of the member.
Claim 8
Dependent Claim
90 words
Apparatus for heating and conditioning hair curling rollers comprising a closed vessel having a pan-like base and a cover for the base, a roller support tray disposed within said base and spaced above the inside bottom thereof, electrical means located beneath said tray adjacent the inside bottom thereof for heating water in the base by applying potential to the water between a pair of immersed electrodes, said cover including on its inside surface a plurality of alternating radial ridges and grooves inclined downwardly from the center toward the rim thereof.
Claim 9
Dependent Claim
90 words
Apparatus for heating and conditioning hair curling rollers comprising a closed vessel having a pan-like base and a cover for the base, a roller support tray disposed within said base and spaced above the inside bottom thereof, electrical means located beneath said tray adjacent the inside bottom thereof for heating water in the base by applying potential to the water between a pair of immersed electrodes, said cover including on its inside surface a plurality of alternating radial ridges and grooves inclined downwardly from the center toward the rim thereof.
Claim 10
Dependent Claim
70 words
Apparatus as in claim 7, including a standpipe extending upwardly from the inside bottom of said base and having a vertical passageway therethrough continuing through the bottom of the base and providing a water level control, and buoyant cap means normally covering said pipe but floatable to an uncovering position in the event of increase in the level of water to a level above the upper end of said standpipe.
Claim 11
Dependent Claim
22 words
Apparatus as in claim 8, said cap having a small perforation therein permitting limited steam flow therethrough into and through said passageway.
Claim 12
Dependent Claim
73 words
Apparatus as in claim 7, said base having an opening through the side wall thereof near the upper edge, and a baffle plate on the exterior of said base partially screening said opening and forming a water trap on the exterior of said base, said base further including drain channels from said trap back into the interior of said base for drainage of water from said trap to the interior of the base.
Claim 13
Dependent Claim
25 words
Apparatus as in claim 7, including a member supported on said tray having a cup-like chamber therein for receiving and storing a hair conditioning composition.
Claim 14
Dependent Claim
87 words
Apparatus as in claim 11, sAid member comprising an upstanding tube having its lower end adjacent the center portion of the tray and having the receptacle recessed in the upper end, said receptacle having a perforation in its bottom, and means between the lower end of the member and the tray providing passageways between the inside and outside of the member for flow of liquid descending to the member from said receptacle from the interior of said member onto the surface of the tray outside said member.
