13 Claims, 7 Drawing Figures PORTABLE ELECTRIC APPLIANCE FOR STEAMING HAIR ROLLERS BACKGROUND OF THE INVENTION This invention relates to new and useful improvements in hair setting and curling devices and more particularly to devices of the latter type employing means for heating and moistening hair rollers with steam or other vapor.
Portable electrical hair curler appliances for home use which areadapted to heat hair rollers to be used in setting and styling of hair of the user are widely employed and well known. These devices usually comprise casings provided for storing the rollers when not in use and in which casings are provided means for heating the rollers. The means for heating the rollers include heated posts, rails or other roller support means which position the rollers within the casing. The heat is transferred from the heating and positioning means through the roller to the outer surface thereof. A variety of means being employed in hair rollers of the latter type in effecting retention and transfer of heat by the rollers during use. In other type electric hair curlers, the hair rollers are disposed in a chest having steam-generating generating means therein whereby the hair rollers are both heated and moistened by steam.
In use of these hair curler devices a cluster of hair is wrapped about the heated roller by the user and pinned in position on the head by a suitable roller clip. The heat is transferred from the surface of the roller to the hair with the heat from the roller providing a tight and attractive curl. The curl varying of course in accordance with the particular size of roller used, the length of time the roller is left in the hair and the heat retention qualities of the roller. In devices utilizing steam heated and moistened rollers when the cluster of hair is wrapped about the roller the moisture is transferred to the hair and in combination with the heat from the roller efiects a soft, natural curl to the cluster of hair when the roller is removed.
Both types of hair curler devices, that is, those which apply moistened heat to the rollers and those which provide dry heat, have been found satisfactory in use. Certain problems are presented, however, in the dry heat-type devices in that each hair roller must be individually mounted or connected with the heat-generating means, such as the mentioned posts or rails by the user thereby presenting inconvenience in storage and heating of the hair rollers. Further hair rollers required for these type units in most instances comprise a plurality of parts and elements which increase the costs and assembly procedures for the entire unit. The steam-generatingtype hair curler presents an advantage in that the rollers may be disposed at random in the unit and the individual rollers are of less complex structure. Certain problems are present, however, in that for example in known-type units the steam generated within the storage casing that is transmitted to the rollers stored therein is also dissipated outwardly of the unit when the same is opened to remove the heated rollers therefrom. Further problems are present in providing means for removingthe rollers without discomfort to the user in that in known devices the user must place her hand over the area from which the steam is generated. Further hair rollers used must not only have heat retention qualities to retain heat but also must transmit the heat effectively and rapidly with the moisture.
It is an object of the present, invention, to provide a novel hair curler device.
Another object is to provide a novel hair curler device wherein novel means are provided for storing and heating hair rollers through moisture.
Another object is to provide a novel hair curler of the steam moistening type wherein novel means are provided for storing anddispensing the hair rollers in heated or unheated condition.
A further object is to provide a novel steam-type hair curler and hair roller storage means wherein means are provided for dispensing the rollers with a minimum amount of loss of steam and moisture fromthe storage area.
A still further object is to provide a novel hair roller for use in steam generating type hair curler units.
SUMMARY OF INVENTION The present invention contemplates a novel electric hair setting and curler device including novel hair roller storage and steam generating device for heating and moistening a plurality of hair rollers. In one embodiment, the device comprises a casing having a compartment for storing hair rollers. The rollers are disposed within a drawer which is movable into and out of thecompartment. Heating means are provided within the storage compartment in association with fluid reservoir means and which heating means is operable to heat and vaporize the fluid in the reservoir for dispersion about the rollers in the storage drawer. Means are provided to stop and tilt the drawer as it is partially projected through the opening of the compartment and which means include means for detenting the drawer in tilted position and restraining further movement beyond said tilted position.

A suitable high-heat resistance sealing adhesive 54 such as that commonly referred as RTV adhesive comprising a silicon rubber base adhesive is provided between the adjacent surfaces of the base 24 and heating plate 47. The capacity of reservoir 20 is preferably of approximately 6 ounces of fluid. As will be appreciated the downwardly sloping configuration of bottom wall 24 (FIG. 5) adjacent reservoir 20 provides for containing any overflow of fluid (as illustrated in FIGS. 3 and 5) from reservoir 20 and for returning in liquid form condensation of steam that might be generated by reservoir 20 as will be described.
A thermostat 55 is secured to and beneath the central raised portion 56 of heating plate 47 (FIGS. 3 and 5), and regulates the shutoff temperature of heating element 48 in a usual manner; A metallic rectangular shaped bottom cover plate 58 is provided beneath heating plate 47 and extends between front and rear supporting legs 59 to cover the bottom of unit 10.
The support means for hair rollers 16 include drawers l2, l3 and 14. Each drawer as shown with respect to one drawer 13 shown in FIGS. 6 comprises a rectangular box shaped member having sidewalls 61 and 62 respectively and having cut out recess portions 63 in the forward portions thereof. The front walls 64 of each drawer in closed position of the drawer lie flush with front wall 23 of casing 11 and provide second closure means for storage compartment 18 in addition to the 'cover 40. A series of spaced and parallel slotted openings 65 Means are provided for selectively limiting movement of drawers 12, 13 and 14 outwardly of compartment 18 in order that one roller 18 in each drawer is removed at a time from the drawer by grasping the opposite ends of the particular roller 16 located at the cut out portions 63 in sidewalls 61-62 of the drawer (FIGS. 1 and 5). To this end drawer tilting and stop means are provided in compartment 18 for each drawer. As seen in FIGS. 1 and 3 a pair of partition panels 68 and 69 are provided in compartment 18 and together with sidewalls 31 and 32 provide three separate channel areas within companment 18 for drawers 12, 13 or 14. Each drawer is provided with identical channel areas and stop means and therefore the description herein is directed to only drawer 13. As shown in FIGS. 2, 3 and 5, drawer 13 is disposed between panels 68 and 69 and which panels are provided with triangular shaped cam projection 71 at the lower rear portion thereof. The spaced rear lower inner portions of drawer 13 (FIG. 6) are provided with projections 73 having notches 74 in the base thereof.

Positioning plaques 76 are provided on the front portions of panels 68 and 69 and have downwardly inclined surfaces 77 in alignment with similarly oppositely inclined surfaces 78 on the lower front of sidewalls 61 and 62 of drawer 13 for guiding drawer 13 into and out of its storage area. Detent 80 is provided on plaque 76 to lie in recess 81 in surface 78 of drawer 13 to detent the drawer against movement outwardly of compartment 18 in the closed position of the drawer.
In FIG. 7 an electrical circuit for unit 10 is shown. Thermostat 55 is designated T and heating element 47-48 is designated I-I. Plug prongs for an appliance cord (not shown) for unit 10 is designated P and having prongs P1 and P2 is adapted for connection to a source of alternating power as is available in a usual household outlet. Thermostat T is connected over input prong P1 in series with heating element H.
' On off switch 37 is designated KS and light 40 is indicated and L with a protective resistor therefore designated R1. Light bulb 1 is connected in parallel with thennostat T and element H and is adapted to be lit when plug P is connected in the electrical outlet. Thermostat T interrupts supply power to element H in a usual manner when a desired temperature is reached during operation.
The individual hair rollers 16 are hollow and have opposite end rim portions 84. Rollers 16 as desired may be of the same diametric dimensions or vary in diametric dimension in accordance with the needs of the user and the size of curl to be wound. Rollers 16 are molded from a high heat retentive material. It has been found that a high and/or medium density type polyetholene plastic material is of particular excellent heat retention and heat transfer qualities for use in the above unit. Polyetholene material of the latter type having a density of medium to high within the range of 0.926 to 0.965 g./cc., have been tested and used in the described preferred embodiment. Rollers made of high-density polyetholene within a range of 0.941 to 0.965 g./cc., of a thickness of approximately 0.150 inches have been found to be most suitable and desirable in heat retention and moisture retention qualities whereat heated to a temperature of C. effect a rapid transfer of moisture and heat to the hair of the user to effect a natural curl in a period of time of approximately 6 minutes. The moisture applied to the rollers of this material and heat being evenly distributed by the roller and transferred from the roller to the hair providing a more softer and natural curling effect then heretofore effected by known similar devices.
In accordance with the above-described arrangement, if a person desires to use unit the cover 44 is moved to an open position to expose the interior of drawers 12, 13 and 14. The drawers are then filled with the desired number of hair rollers 16 by placing rollers 16 end to end within the drawers in side by side relationship. A desired amount of water is then poured down over the rollers and which water passes down into reservoir through openings 65 in the base of the drawers. Unit is then connected to a suitable electrical outlet through a suitable power cord (not shown). Switch 39 is moved to an onposition to activate heat element 48 thereby converting the water in reservoir to steam with thermostate 55 controlling the operation of the element 48 in a usual manner to open the circuit thereto when plate 47 reaches a selected temperature. In the on-position of switch 39 light 40 is lit to indicate that the unit is connected to an electrical source. As the water is converted to steam by plate 40 the steam is dispersed upwardly into the roller drawer 12, 13 and 14 through the slotted opening 65 therein to heat and moisten rollers 16. The closure door 44 and front walk 64 of the drawers preventing escape of the steam from the unit.
As will be appreciated since only one roller 16 is to be used at a time it is preferable that only limited access be permitted to storage compartment 18 so that the steam generated therein does not escape whereby the remaining rollers within the compartment lose their moisture and heat. It is preferable, therefore, that only one drawer, 12, 13 or 14 at a time be withdrawn from compartment 18 to maintain the other rollers in a heated and moistened condition. To accomplish this the user grasps the finger portion 87 on the front closure wall 64 of a drawer selected and pulls the same outwardly of compartment 18. As the drawer moves outwardly of compartment 18 (as shown in broken lines in FIG. 5 with respect to drawer 13) the rear comer projecting portions 73 thereof engages camming triangle surfaces 71 in the path of movement thereof on the panels 68-69 in the compartment 18. The rear portion of drawer 13 is thereby raised as the same moves up the cam portion 71 and at the same time the drawer projects outwardly of the compartment. As seen in FIG. 5 when projection 73 move to the apex of cam portions 71 the notches 74 therein engage the top of the cams 71 effecting a restraining action on the pull of drawer l3 outwardly of compartment 18. Under these conditions the user is alerted and releases finger piece 87. In this position only that portion of drawer 13 adjacent cut out portions 63 in sidewalls 61-62 thereof projects outwardly beyond front wall 23 of casing 11. In this position only the leading roller 16 in drawer 13 is fully exposed (FIG. 5). The first roller may be grasped by its opposite end at out out portions 63 in the drawer walls and removed. Due to the tilted position of drawer 13 as maintained by the stop means the next roller 16 will roll on its rims 84 to position at the front of the drawer in a self-feeding manner.
It is desired that the entire drawer 13 may be removed from compartment 18 by pulling the same downwardly and off camming projections 73 and out of the compartment. If the drawer 13 is returned to the storage area within compartment 18 by aligning'the inclined surfaces 78 on the drawer with the aligning inclined surfaces 77 on plaques 76 on the sidewalls of the areas and sliding the drawer back into compartment 18. When drawer reaches the rear of compartment 18 of the detents 80 on plaques engage in recess 81 on inclined surface 78 of the drawer to effect a holding of the drawer within the easmg.
As will be appreciated from the foregoing designation the novel hair curler has many advantages in use. Among other advantages an efficient and economical means for preventing dissipation of stem outwardly of compartment 18 during use is provided through enclosure cover 44 and the positioning of front walls 64 of drawers 12, 13 and 14. The novel means for stopping and tilting the drawers to permit a self-feeding of the rollers in moistened condition. Since only one roller is usually exposed the next roller in the drawer provides an additional means to prevent steam from escaping the storage compartment thereby maintaining the rollers warm and moist at all times. The composition of the hair rollers 16 as described also provides for a low cost and efficient means of containing and transmitting heat to the moistened and set hair when the rollers are placed therein.
Although one embodiment of the present invention has been illustrated and described in detail, it is to be understood that the invention is not limited thereto. Various changes can be made in 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.
