ELECTRIC HEATER FOB CURLING IRONS.

Application filed June 3, 1925. Serial No. 34,507.

To all whom t may concern.-

Be known that I, DAVID WV. VAN TINE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Electric I-Ieater for Curling Irons, of which the following is a specification.

My invention relates to a novel construction of electric heaters for curling irons, wherein I employ an outer casing which contains a central core of insulating material around which the resistance coils of the electric heating elements are wound, the space between said core and said casing being filled with suitable non-conducting ma terial of such a character that when an electric circuit is closed 'the latent heat within the casing will. keep the heater hot for a considerable period of time.

It further consists of a novel construction of heater casing and end supports having oppositely disposed laterally extending arms which serve as supports for curling irons at the will of the user.

It further consists of a novel construction of a hollow, central insulating core having a shoulder which abuts against the front end closure of the heater casing, whereby a finished apeparance is given to the device and whereby the latter can be readily assembled, thereby cheapening the process of manufacture.

For the purpose of illustratingmy inven tion I have shown in the accompanying drawings two forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Fig. 1, represents a perspective view of an electric heater for curling irons embodying my invention` Fig. 2, represents a longitudinal section on line 2 2 of Fig. l.

Fig. 3, represents a transverse section on line 3 3 of Fig.2; and

Fig. 4, represents a perspective view of a slightly imodified forni of .curling iron supportj 4 i' Referring to the drawings, in which like reference characters indicate like parts, l designates my novel construction of a curling iron, the same comprising a casing 2, within which is located the centrally. disposed core, 3, open at both ends, and which is provided at its front with a beveled end 4 and having the rear shoulder 5 which ahuts against the closure or cap (i, which cap is provided with a. rearwardly extending flange 7. S designates an encircling ring which surrounds the flange 7 and is provided with a vertical lower member which terminates in the feet l0, which are secured to a suitable base Il by the screws or other fastening devices 12. 13 designates horiffzontally or laterally projecting arms which have the outer vertical terminals 14 said arms being provided with the downwardlj.y extending flanges l5, which are secured in position by the bolts 16, the latter passing through the members 15 and l), as will be understood from Fig. 3. 17 desig naties the electric heating or resistance coil, which preferably enters the rear wall 1S of the heater and which is so constructed. in proportioil to the here or chamber lll of the core 3, that said bore or chamber will be effectively heated to the desired degree under all conditions. The space between the core 3 and the casing 2 is filled with suitable non-conducting` material as indicated at 20, which retains latent heat from the heat-ing coil so that when the electric circuit is open the device will function for a. long period of time as a heater. Thus only a minimum quantity of electricity is required.

In the construction seen in Fig. 4, I have shown a preferred form of end closures 21 wherein 22 designates the disc or closure member having the central hole 23 therein, through which the core 3 is inserted. 24 designates the horizontally or laterally eX- tending arms and 25 the foot whereby the device is supported upon and secured to the base l1. 26 designates a rearwardly extending flange which is adapted to receive the ends of the heater casing 2. The construction seen in Fig. 4 is substantially the same as that disclosed in Fig. 3 except that, being a unitary structure, it can be more readily assembled upon or disconneeted from the ends of the easing 2, said ends fitting nicely within the flange 25 as is evident. By constructing the heater .with

the end closures 2l, as seen in Fig. 4, it is apparent that the number of parts 1s re duced to a minimum, since, aside from the heating coil, it is only necessary to employthe core 3, the casing 2 and the end closures 2l, which parts, when assembled, Will function efficiently as a heater for curling irons or other purposes. The provision of the arms 13 or 24:v affords a convenient support for the heated curling irons, While they are temporarily not in use. The provision of the beveled end al, and the shoulder 5 enables the core 3 to be readily and quickly inserted in position as is evident.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. A device of the character stated comprising a casing member, flanged caps for closing both ends thereof said caps fitting over said casing member, a tubular member arranged Within said casing member and projected through one end thereof to receive an article to be heated, a heating coil surrounding said tubular member, a base, means carried by said base to support the caps of said casing member and laterally disposed rests at each end and upon both sides of the device and rigidly clamped directly to said base for supporting articles `to be heated.

2. A device of the character stated comprising a casing member, flanged caps for closing both ends thereof said caps fitting over said casing member, a tubular melliber arranged Within said member and projected through one end thereof to receive an article to be heated, the projected end of said tubular member being tapered and having an exterior shoulder Which abuts against an adjacent cap exterior, a heating coil surrounding said tubular member, a base, means carried by said base to support the caps of said casing member and laterally disposed rests at each end and upon both sides of the device for supporting articles to be heated.

3. A device of the character stated comprising a cylindrical member, flanged caps for closing both ends thereof said caps fitting over said casing member, a tubular member arranged Within said cylindrical member and projected through one end thereof to receive an article to be heated, a heating coil surrounding said tubular member, a base, means including a right angle member formed integral With said caps and carried by said base to support the caps of said cylindrical member and laterally disposed rests including oppositely disposed, laterally extended, horizontal arms at each end and upon both sides of the device for supporting articles to be heated.

In testimony whereof, I have hereunto signed my name.

DAVID W. VAN TINE.
