July 8, 1969 Q L, KEMP ET AL HAIR ROLLER HEATING APPARATUS Filed April 13. 1966 In z- 7 INVENTORS (LAKE/pill KEMP DJ/f/ervv/q l AND TW/CK A T TORNEY United States Patent O Filed Apr. 13, 1966, Ser. No. 542,371 Int. Cl. F2711 11/00 U.S. Cl. 312-31 5 Claims ABSTRACT OF THE DISCLOSURE The disclosure herein is of a hair roller heating apparatus involving a cabinet in which trays are supported, which in turn support the usual cylindrical hair rollers of varying diameters and lengths each of said trays being hinged to the other for access to the lower of the two, there being heating means provided in the cabinet with means to circulate such heat so that the rollers are preliminarily heated and thus available for use in hair curling, access to the rollers being in an endwise manner through openings in the lower ends of the columns in which they are stacked in the trays mentioned.

This invention relates to hair roller heating apparatus and more particularly to a novel form of such apparatus which substantially increases the production of heated rollers, and more uniformly heats the same and makes them readily available for use.

The invention herein presents a substantial improvement over that disclosed in our co-pending application Ser. No. 453,409, filed May 5, 1965, wherein one form of hair curler oven or heating apparatus was disclosed together with the method wherein the apparatus is used and which most substantially increases the productivity of an operator.

It is a primary object of this particular invention as it was of the earlier invention, to supply heated rollers for use in either commercial or home hair curling operation, so that the time required for completely drying the hair and thus providing the curling effect desired is substantially reduced. In fact by the instant invention in most cases such time reduction may be fifty percent and in many cases even more, a substantial improvement as will be readily recognized.

In our earlier application, the method of use of the curlers or rollers heated by the invention disclosed therein, was setforth, and the invention in that particular form as to the oven,.resided in supplying the rollers by supporting them on rods whereby they were supplied one at a time. The construction of heating apparatus to load the rods with the rollers prior to treatment, in such a manner as to have the same most accessible, was somewhat cumbersome and not as efiicient as the instant apparatus provided therefore.

With the foregoing in mind, it is therefore a principal object to provide an improved form of hair roller heating apparatus, in which the hair rollers are supported so that heated air may be circulated therearound, and the rollers available for removal from the apparatus one at a time at any particular time desired, the loading or preliminary filling of the machine so to speak being effected in a very simple manner.

A further object of the invention is to provide as improved form of hair rollerheating apparatus in which the rollers are supported in columnar position, with rows or columns of rollers side by side in a generally vertical arrangement so that they may be withdrawn one at a time through an opening provided at the lower ends of the columns, provision for different lengths of rollers to be heated and manipulated from the apparatus being made.

A further object of the invention is to provide a novel form of roller heating apparatus in which the heating is effected in a simple manner, under the control of thermostatic elements with circulation of heated air being effected, and made particularly eflicient by the provision of certain foraminated portions of a supporting means for the rollers so that the heat will be circulated through the rollers as well as around the same.

Other and further objects of the invention will be understood from a consideration of the specification appended hereto and disclosed in the drawings wherein:

FIGURE 1 is a front view of the apparatus of this invention showing the general form thereof.

FIGURE 2 is a side elevation of the apparatus disclosed in FIGURE l.

FIGURE 3 is a cross-sectional view of the apparatus taken about on the line 3-3 of FIGURE 1 looking in the direction of the arrows with the door or closure means open.

FIGURE 4 is a front view of roller supporting means` FIGURE 5 is a sectional view of the disclosure in FIGURE 4, taken about on the line 5 5 of that ligure looking in the direction of the arrows.

Referring now to FIGURE 1, the apparatus hereof is shown as comprising a housing generally denoted 1, with the rear face or Wall 2, a bottom y3, top 4 and ends 5 and 6.

As will be observed from FIGURE 2, the housing is a sort of truncated right angle member in side view, the

ffront of the apparatus or of the housing being provided with a closure means generally denoted 7, hinged at one edge thereof at 8 so as to open into the position disclosed in FIGURE 3 in order to facilitate access to the interior of the housing for purposes which will be ap- ',parent as this description proceeds.

It should be noted that the housing 1, in general, is provided with insulated walls because it is desirable to retain heat therein.

The heat in the housing is developed in this particular instance as by means of quartz tube heaters 9l and 10, which extend generally transversly, and are supported on a suitable support 11 which in turn extends upwardly in the housing from the base or bottom 3 thereof the heaters being connected to a suitable control means designated 12 in any manner which will be apparent to those skilled in the art.

The control means 12 is provided with a suitable rheostat such as 13 to regulate the heat output of the heating means or quartz tubes 9 and 10, the control means further incorporating therein a suitable thermostat control and switches, the thermocouple element of the thermostat being designated 14 and arranged along the bottom or base 3 and slightly thereabove so as to best regulate the temperature within the housing 1.

A suitable fan such as 15 is positioned at the lower portion of the rear 2 of the housing, driven by an electric motor 16 which in turn is controlled from the control means 12 as by a switch such as 17 for example there being

indicator lights

18, 19, and 20, the latter controlled by a switch 21 to regulate the operation of the fan motor 16 and the -heater elements or means 9 and 10v and fan may be turned on or ofr if necessary. The rheostat 13 is of course availed of to control the current supply to the heating elements 9 and 10.

Suitable support means are provided for the rollers which are of the conventional type and not described in detail, although desirably either plastic or yliber or some similar material and generally of varying diameters and lengths, in this instance provisions for two lengths being provided. The support for the rollers which will be referred to as to their size more in detail hereinafter, is

provided within the housing 1 by means of vertically extending angle members 22, suitably spaced and positioned adjacent the side walls 5 and 6 so as to receive therebetween the tray unit or roller supporting means generally designated 23. This tray unit or roller supporting means comprises a pair of

trays

24 and 25 shown in separate detail in FIGURE 5, the tray 25 hingedly connected .at 26 to the upper end of the tray 24 so as to be movable into the dotted line position shown in FIGURES 3 and 5.

The trays are substantially identical and as indicated in FIGURE 4, a `series of columns is provided by means of the dividers such `as 27, 28, 29, etc., which by reason of the spacing thereof will accept rollers of varying sizes in parallel columns.

The tray 25 is similarly provided with spacers such as 30, 31, 32, etc., the tray 25 being of less depth than the tray 24 so that shorter rollers may be supported therewithin.

It is noted that the back or bottom of each tray which may be designated 24a for

tray

24, and 25a for tray 25, is comprised of a foraminated metal member whereby circulation of air may be effected through the bottom and thus through the rollers supported in the trays since the rollers .are round cylindrical members as shown.

It should be noted that the roller supporting means, involving the first and

second trays

24 and 25 respectively may be removed from the housing 1 as a unit through the front thereof, when the main closure means or door 7 is opened.

The trays may be loaded so to speak when they are in position in the housing by raising the tray 25 into dotted line position such as indicated in FIGURE 3 and loading the tray 24, thereafter repositioning the tray 25 and loading that in a similar manner.

In order to provide for removal of the rollers one at .a time, from the various columns, suitable doors or access means 33 and 314 are hingedly connected at 35 and 36 respectively on the inner faces of the door 7 so as to close or permit access through the access means 37 and 38 respectively, these latter being generally triangular shaped openings positioned, when the main door 7 is in closed condition, opposite the lower row of rollers in the respective clumns of the respective trays.

The purpose of the doors 313 and 34 is of course to facilitate the closing of the entire unit when it is desired initially to warm the rollers therewithin and when in use the doors or one of them may be opened so as to provide for access through the respective access means 37 and 38.

As noted the door 7 is provided with an offset so that easy grasping of the rollers in the respective trays may be effected for withdrawal thereof through the access means provided.

A suitable latch means such as 40 may be availed of to retain the door or closure means 7 in closed condition this being the usual type of rotatable latch member and likewise providing a handle to open the door.
