2 Claims. (Cl. 219-35) This invention relates to the general art of beauticians appliances and, more specifically, is for an improved device for heating various implements that are used by hairdressers, as for instance irons, combs, etc.

The object of my present invention is to devise a container within which may be placed the implements to be heated, together with means whereby the heating may be preliminarily set for a desired temperature and automatically discontinued when such temperature is reached.

Another object is to devise suchv an appliance with a signal light that will be automatically extinguished when the heating is discontinued.

Another object is to devise such an appliance with means for conveniently and etiiciently supporting the handle portions of the implements when in heating position.

A still further object is to devisesuch an appliance with means for conveniently supporting the implements either before or after placing the same within the container for heating.

Other objects will appear from the following description and claims when considered together with the accompanying drawing.

Fig. l is a perspective view of my present device;

Fig. 2 is a wiring diagram of the electrical means;

Fig. 3 is an end elevation of the device.

Reference will now be had to the accompanying drawing in detail although it is to be understood that the present form of disclosure is merely for the purpose of illustration and that there might be various modifications thereof without departing from the spirit of my invention as herein set forth and claimed.

Upon the base 1, which may consist of any suitable material, there is tixedly mounted the duplicate combined leg and

end members

2 and 3. Each of these members has a pair of legs 2a and 3a, respectively, aixed to the base 1 and is open through the upper parts 2b and f 3b, respectively. The parts 2b and 3b may be of circular or polygonal form and are adapted to receive and hold the ends of the tubular` body portion 4 which may be of substantially the same cross section as the upper parts 2b and 3b so as to have interengagement therewith. That is, the ends of the body 4 may have abutting engagement against the portions 2b and 3b, and the annular members 4a and 4b may surround the body part 4, thereby providing seating engagement for the ends of the body 4. These parts are held in assembly by the oppositely disposed rods 5 that extend through the upper parts 2b and 3b and the annular members 4a and 4b and alongside the body part 4. By tightening the nuts upon these bolts, these parts may be held in assembly, as indicated in Fig. 1 of the present drawing.

Also mounted upon the at top of the body part 4 and extending the full length thereof so as to have clamping engagement at its two ends between the upper portions 2b and 3b, is the heat-conducting strip 6 upon which is xedly mounted the thermometer 7. The strip 6 may be formed as the upper part of the wall of the body 4 so as to be exposed directly to the heat within the container and the remainder of the container wall might be heat-insulated. Or the entire outer wall of the body 4 may be heat-insulated except to the extent of the base of the thermometer 7 so as to expose the same to the heat within the container.

Within the wall of the container body part 4 there are concentrically arranged a plurality of electric heating coils 8 for different degrees of heat, as for instance 100 degrees, 200 degrees, 300 degrees, 400 degrees and 5 00 degrees, respectively, as indicated in the accompanying drawing. Each of these heating coils may extend the full length of the body part 4 of the container and they are all continued in the form of wiring connection through the cable 9 to the rotatable hand switch 10 near the one end of the base 1; and this switch in turn has an electric cord with a plug 9a for insertion in a base socket when it is intended to install this device. This switch has points of contact corresponding to the several different degrees of temperature as above referred to and as indicated in Fig. 2 of the present drawing; so that, upon contacting the hand switch 10 with one of the companion contact points, there may be then obtained a corresponding temperature within the container. That is to say, the circuit may be closed through the 100 degree coil, for instance, or through any one of the other coils so as to obtain the temperature corresponding thereto.

In each of the several branch circuits including the several coils 8 there is provided a bi-metallic switch 11 which is designed to automatically open when the heat reaches the temperature corresponding to that of the coil in the closed circuit as determined by the position of the switch 10, so that the current will be automatically cut olf at such predetermined selected point.

Also, a signal electric lamp 12 is enclosed within the hollow middle part of the rotatable switch member 10 so as to be viewable through a Window 12a in the top thereof. This lamp is in circuit with the electro-conductive part of the arcuate switch element 10a so as to be lighted whenever the switch is placed upon one of the contact portions of this element 10a; while the intermediate portions 10b are non-conductive electrically. Thus the light 12 will be automatically extinguished when the particular bi-metallic switch is opened upon attainment of the temperature for which set. Upon moving the switch 10 to position upon any one of the non-conductive portions between the contact portions, the current may be cut o and will so continue until the switch 10 is moved to position upon one of the contacts; and the light 12 will also continue off during the same length of time.

The upright rack 13 aixed upon the base 1 may serve to support the handles of the implements while the other end portions thereof are in heating position within 4the container. Such a rack may be provided at each end of the container so as to permit the implements to be inserted within either end of the container.

Also, the horizontal arms 14 may be slid into and out of the body 1 upon either or both sides thereof so as to afford means of convenient support for the implements either before or after the heating of the same within the container.

With this device there may be avoided the overheating of the implements and the consequent damage that might be done to the scalp and hair of the patient. This is made possible by the automatic control herein described and also the signal light further serves to indicate to the operator whether the current is on or off, that is whether the device is or is not heating and whether the desired point of heating has been reached.

Furthermore, with the thermometer 7 in heat-conductive relation to the interior of the container, there will be afforded at any and all times a visible indication to the 3 operator as to the temperature within the container and this is calculated to prove quite a practical advantage whether the electric circuit is closed through any of the heating coils and either before or after the temperature of the interior of the container has reached the point for which set, as above explained,

Other practical advantages resulting from the present invention will no doubt readily suggest themselves to those who are familiar with the art to which it relates.

What I claim is:

1. A beauticians appliance comprising a container for holding implements, a plurality of electric coils of different electric resistances arranged concentrically about said container so as to heat the implements placed therewithin, an electric circuit including said coils arrange in parallel therein, said container having an open end for insertion of that part of an implement that it is desired to heat, a rack spaced from but adjacent to the open end of said container for supporting the handle part of the implement that is in position for heating, and an adjustable switch for selecting any one of said coils at a given time for energization, and a heat-responsive switch in circuit with each of said coils for automatically opening the circuit therethrough upon attaining the temperature corresponding to that of the selected coil at any given time.

2. A beauticians appliance comprising a base, a hollow tubular container mounted upon said oase and having an open end for receiving and holding implements therewithin, a plurality of electric coils of diierent heating potentials arranged concentrically within the body of said container and about the same so as to heat the implements placed therewithin, a rack mounted upon said base and adjacent to the open end of said container so as to afford support for the handle part of an implement while its other end part is within said container, an electric circuit including said coils arranged in parallel therein, and an adjustable switch for selecting any one of said coils at a given time for energization, a heat-responsive switch in circuit with each of said coils for automatically opening the circuit therethrough upon attaining the temperature corresponding to that of the selected coil at any given time, an electric lamp included in circuit with said adjustable switch so as to be energized only during the period of energization of any one of said coils and to be automatically de-energized upon opening of its heat-responsive switch, and an implement-supporting means having lateral sliding engagement with said base so as to be movable into and out of operative position and extending substantially normal to the longitudinal axis of said container and adjacent thereto.
