Kearns 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.
This invention relates to new anduseful improvements in hair setting and. curling devices and more particularly to devices of the latter type employing hair rollers and'heating means therefore.
Hair. setting and curling devices which include means for heating hair rollers to a selected temperature for use in the curling or'setting of awomans'hair are wellknown. These devicesusually comprise a casingwherein means are provided for detachably supporting hair rollers and wherein other means are provided for heating the supporting'means whereby heat is conductedto the hair rollers. The rollers retain the heat and in use when the same are heated'to a desired temperature they are removed from the supporting'means. A cluster ofhair is wound about the heated outer surface of theroller andas a result of the heat imparted to the cluster of hair by the roller the former is more readily curled andthe roller may be removed from the hair after only several minutes.

DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawings for a more detailed description of the present invention, a hair-settirig'device which incorporates one embodiment of the present invention is generally indicated by "the reference numeral 12. Device 12 (FIG. 1) comprises a casing which is preferably made of premolded plastic material and includes a container section 14 and cover section 15 and inwhich container section 14 is providedheatingapparatus-generally indicated by the numeral 16 'in'FIG. '1 forheating' hair rollers 17 arranged thereon.
'and 15 in closed relationship as desired. Handle extensions 29 are provided on each section 14-l5 and as shown in FIGS. 4 and 5 rear walls 22 have foot projections 30 formed on the outer surface thereof whereby device 12 may he stood in a vertical position ('FIG. 5) when not in use. In addition a mirror 31 is secured to the inner face of rear wall 22 of cover section 15 by a suitable adhesive 32 (FIG. 2). I
Asmentioned itis a feature of the present invention to provide novel means for heating hair rollers 17. To this end the heating apparatus 16 includes a frame member 35 formed of a suitable plastic material and which frame 35 is provided with sidewalls 36, a front wall 37, and a rear wall 38. Frame 35 is disposed in container 14 with sidewalls 36 (FIGS. 1 and 2) abutting against sidewalls 20 of container 14. The rear wall 38 parallel tapered bars 52 extending'transversely of plate 49. A
U-shaped tubular heating element 54 (FIGS. 2, 6) is cast on the opposite face of plate 49 and includes therein a suitable well-known heating means such as a resistance wiring encased in compressed magnesium oxide. End terminals of heating element 54 have suitable electrical connections (not shown) with appliance cord 41 and a terminal board 58.
Terminal board 58 (FIGS. 3, 6, and 9) comprises a rectangular-shaped insulated member secured to an extension 59 of plate 49. Indicator lamps 61 and 62 are mounted on terminal board 58 and are visible at appropriate aperture portions in panel 43 (FIGS. 1 and 2) for purposes to be explained. A thermostat 64 having a rotatable control knob 65 is disposed on panel 43 and extends downwardly through a passage 66 (FIG. 3)'to terminal board 58 and has a suitable connection with a heat sink 68 (FIG. 6) provided in plate 49' and through which heat sink 68 heat is conducted from heater element 54 for controlling operation of thermostat 64 and correspondingly the temperature of plate 49.
Locating means (FIGS. 8, 9 and 11) are provided within cylinders 70--7l for insuring the alignment of recesses 72- 73 and include a boss 76 on the vupper inner surface of cylinder 70 adapted to engage in cut out portion 77 of core 71 when the latter is inserted in cylinder 70. In this manner core 71 can be located in only one position in cylinder 70 and is fixed against rotation therein.
The outer surface of cylinder 71 is provided with comb teeth 80. As seen i FIG. 8, teeth 80 are arranged in a first pair of diametrically opposed group of three rows and a second pair of diametrically opposed pair of single rows with the surface between the groups of teeth being smooth. The latter arrangement of teeth 80 being effective to comb hair wound about cylinder 70 in an efficient manner.
Although the above description is directed to one of the rollers 17, it is to be understood that the other rollers 17 are of the same construction and will differ in certain instances only in dimensions. As illustrated for example, the rollers 17 identified A, B and C in FIGS. 2 and 3 have varying diameters a, b" and c." Each roller, A, B and C however is provided with groove 75 of the same height x." and width y. As a result rollers A, B, C all have the same mounting means whereby the latter are accommodated on rails 52 without the necessity of providing rails of varying dimension to support rollers 17.
In FIG. thermostat 64 is designated T and heating element 54 is designated H. The plug prongs of appliance cord 41 adapted for connection to a source of alternating power such as available in the usual household outlet are designated M1 and M2. Thermostat T is connected over input prong M1 in series with heating element I- IfLights 61 and 62 are indicated as L1 and L2 respectively with protective resistors thereof designated R1 and R2 respectively. Light L1 is connected in parallel with thermostat T and element Hfarid isadapted to be it when prongs M1 and M2 are connected to a suitable outlet. Light L2 is adapted to be connected ins'ries with heating element H under conditions where thermostat'T interrupts applied power to element II when the desired temperature is reached and sensed by thermostat Tn'a usual manner.
In accordance with the above described arrangement, if a person desires to use device 12, appliance cord 41 is con- .nected to a suitable outlet and rollers 17 are mounted on rails 52 as described. Thermostat 64 is then set to a desired temperature by rotating knob 65 thereof to a selected position between temperature ratings indicated High and Low" on panel 43 in F IG. 2. Under these conditions heating element 54 is activated to heat plate 49 and rails 52 to the desired temperature with the heat being transmitted to the outer surface of cylinders 70 through inner cores 71 in contact with rails 52. When the selected temperature is reached thermostat 65 operates in a usual manner to interrupt direct power to element 54 and lamp L2 is then lit as it is connected in series with element 54 and provides visual indication that rollers 17 are heated and ready for use.
It will be readily apparent from the foregoing description that the novel device has many advantages in use. One advantage among others is that the novel mounting means provided on rollers 17 allow rollers of varying or the same dimension to be mounted on rails 52 without differently dimensioned heating means or the like. If desired plate 49 may be used to heat at one time rollers of one size or to heat rollers of varying sizes. The fact that these rollers may be closely mounted adjacent each other upon rails 52 results in full utilization of the space available and effects a savings in parts and material. The universal mounting means further results in more efficient and simplified operating procedures in the placement of rollers within the device.
Although one embodiment of the present invention has been illustrated and described in detail, it is to be expressly understood that the invention is not limited thereto. Various changes can be made in the design and arrangement of parts without departing from the spirit and scope of the invention as the same will now be understood by those skilled in the art.
