Abstract

A hairsetter is provided of the type employing heated hair rollers. The hair rollers are heated simultaneously interiorly and exteriorly. The interior heating is accomplished by means of heated mounting posts on which the rollers are supported in the assembly. The exterior heating is accomplished by the passage over the surface of the rollers of a vapor of a heated hair treatment liquid. The vapor both heats the rollers and deposits condensed liquid on the roller surfaces to provide a wet-set. The hairsetter can also be used without employing a liquid but in such case heating of the rollers would be accomplished only by the mounting posts.

Claims

1. A hairsetter, capable of heating hair rollers either with or without the use of a liquid according to the desire of the user, comprising, in combination, a housing having wall means defining a substantially closed chamber adapted to contain water vapor;

a shallow dished-shaped base plate supported entirely within the housing wall means, adapted to receive and retain a quantity of liquid thereon for vaporization;

a plurality of heat conducting roller mounting members associated with the base plate, and adapted to support a corresponding plurality of rollers having a heat conducting surface in contact with and supported by the roller mounting members, said rollers being positioned by said mounting members so as to be exposed to the liquid vaporized from the base plate; and

heating means operatively associated with said base plate for heating any liquid retained on the base plate and the mounting members such that the rollers supported on the mounting members can be heated simultaneously exteriorly by the heated vaporized liquid and/or interiorly by the heated mounting members.

2. A hairsetter in accordance with claim 1, in which the base plate comprises a reservoir for the liquid and has trough-like indentations thereon.

3. A hairsetter in accordance with claim 1, in which the roller mounting members are posts supported by the base plate.

4. A hairsetter in accordance with claim 1, in which the base plate is suspended in the housing in a position spaced from the walls of the housing.

5. A hairsetter in accordance with claim 1 including an apertured cover plate positioned above the base plate having first apertures through which the mounting members pass and second smaller apertures adapted to allow the flow of varporized liquid therethrough.

6. A hairsetter in accordance with claim 5 in which the cover plate is removable.

7. A hairsetter in accordance with claim 1 including a heat conducting plate positioned between the heating means and the base plate and in contact with both the heating means and the base plate for transmitting heat to the base plate.

8. A hairsetter in accordance with claim 1, in which both the base plate and the mounting members are heated by a single heating means.

9. A hairsetter in accordance with claim 1 including means for adjusting the temperature applied to the rollers according to whether the rollers are heated both interiorly and exteriorly, or only interiorly.

10. A hairsetter in accordance with claim 9, in which said means for adjusting the temperature applied to the rollers comprises a thermostat and a heat shield moveable into and out of a position so as to shield the thermostat from exposure to the temperature radiated from the heating element.

11. A hairsetter in accordance with claim 10, in which the heat shield comprises a slideable arm.

12. A hairsetter in accordance with claim 1, in which the heating means comprises a plate-type electric coil heater heater.

13. A hairsetter capable of heating hair rollers either with or without the use of a liquid according to the desire of the user, comprising, in combination, a housing having wall means defining a substantially closed chamber adapted to contain water vapor;

a shallow dished-shaped base plate suspended entirely within the housing in a position spaced from the walls thereof, said base plate defining a reservoir for liquid to be vaporized;

a plurality of heat conducting roller mounting posts supported on said base plate;

a corresponding plurality of hair rollers having a central heat conducting sleeve mounted on the posts in heat conducting contact therewith, said rollers being positioned by the posts so as to be exposed to the vaporized liquid from the base plate;

a cover plate on the base plate having first apertures through which the mounting posts pass, and second smaller apertures through which the vaporized liquid passes;

a heat conducting plate operatively associated with the base plate and mounted beneath the base plate in an abutting relationship thereto, said heat conducting plate also being operatively associated with said mounting posts so as to transfer heat both to the mounting posts and the base plate; and

a plate-type electric coil heater mounted beneath the heat conducting plate and being adapted to heat the heat conducting plate to a temperature of at least 220*F so as to heat the mounting posts and vaporize liquid present on the base plate.

14. A hairsetter in accordance with claim 13 including means to adjust the temperature to which the heat conducting plate is heated according to whether the hairsetter is to be used as a dry-type or wet-type hairsetter.
