ELECTRIC CURLING IRON.

Application filed Catcher 30, 1922. Serial No. 597,773.

To all lwhom it may concern.'

Be it known that I, CHARLES A. Coon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electric Curling Irons, of which the following is a speciication.

My invention relates to electric heating devices, and more particularly to improved elect-ric curing irons.

One object of my invention. is the simplicity of construction and the facility with which it can be used to do the work required. A further object of my invention is the rapidity with which the iron can be heated to the required temperature for curlinfr hair, etc.

ll/ith my invention a suitable socket is provided which is connected to a source of energy, and the curling iron is easily placed in contact with the terminals in order to heat the iron.

My invention will be better understood by reference to the accompanying drawing, in which,-

Figure 1 is an elevation view of a curling iron embodying the features of my invention and shown in contact with a terminal box so as to heat said iron.

Figure 2 is an enlarged sectional view of the heating element.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

As shown in Fig. 1. the curling iron 4 is inserted into a terminal box 5 having end walls 6-6 and side walls ZL-7, one of said walls 6 being recessed at 6a to receive the iron. The other end wall has suitably secured thereto an upper terminal 8 whose inner end 9 is preferably flared to receive the tip 10 of the curling iron. The lower terminal 11 is in the form of a spring and is preferably provided with an enlarged part 12 adapted for engagement with the sleeve 13 of the curling iron. The terminals 8 and 11 are connected to a source of energy 14, shown diagrammatically, for the purpose of heating the iron when desired.

The curling iron embodying the features of my invention has two

handles

15 and 16 of insulating material, one handle being secured to the ferrule 17 into which the sleeve 13 is fastened, as by means of ascrew 18.

The handle 16 is mounted on a member 19 pivoted to the ferrule at 2O and provided with a grooved portion 21 adapted for co-operation with the .sleeve 13 in the curling operation.

@ne end of the sleeve 13 is liluggcd with insulating material 22, such as fibre, and serves to support one end of a central tube 23 whose ,other end is'carried by the tip 10, as clearly shown in F ig. 2. Between sain tip 10 and the sleeve 13 I have interposml an insulating separator 24 mount-ed upon the tube 23; thus it will be seen that the sleeve 13 is entirely insulated from the tube 23. Surrounding the tube 23 is a covering 25 of insulating material which supports the wire 26 forming the heating element, one end 27 being secured to the sleeve 13 and the other end 28 being suitably connected to the tube 23.

I have found in practice thatV after the curling iron has been placed in contact with the terminals 8 and 11, the energy fiowing through the wire 26 will heat the tube 13 very quickly, and the user of this curlingiron will have a. wide latitude of movement owing to the absence of the customary electric cords which have heretofore been employed.

The energy from the source of power 14 flows through the terminal 8 into the tip 10, through the tube 23, wire 26, sleeve 13, spring 11, and back to the source of energy 14.

While I have shown and described one particular embodiment of my invention, I do not wish to be limited to the precise details shown and described, since it will be apparent to those skilled in the art that modifications and changes may be made without departing from the spirit and scope of my invention.

I claim:

1. An electric curling iron comprising an outer tubular member, a support therefor, an inner member carried thereby and arranged within and spaced from said tubular member, a contact tip secured to said inner member beyond the outer end of said tubular member and insulated from the latter, a wire heating element surrounding said inner member and arranged in the space between said inner and outer members, said heating element being insulated from said inner memcurved ber, and having ene end electrically Connected to said inner member and the other te said outer member.

2. An electric curling iron comprising' an outer tubular member. a support therefor, an inner meniber carried by said snoport and arranged within said tnbnlar member. a Contact tip secured to said inner member beyond the outer end ot said tubular member and insulated from the latter; a Wire heating element surrounding` said inner fmember and arranged between said inner and outer members, said Wire having; ene end electrically coiinezfted to the inner end 'v of said inner member and the other end Connected to said fri-ter member near the enter -end thereof.

3. in electric enrling'iron eomprisii'igan enter tubular member. Vhandle for Maid member, a bloel of insulatinf material arranged in the inner end et said tubular member, an inner member Carried by said bloei; and extending ,outwardlyY through said tubular member, a Contact tip seenred to the enter end oi said inner member sind insulated troni the latter, a Wire heating element arranged around said inner member and insulated therefrom, said Wire haring one end electric-albT connected to the inner end of said inner member and the other end to the outer end or' said tubular member.

4. An electric curling iron eon'iprisingv a tubular member, a handle therefor having a socket in which the inner end of said tubular meml is removably secured, a bloei; of insnlating material arranged in the inner `end of said tubular member, an inner member mounted in said block and extending; ont,- Wzirdly through .said tubular member.l .a contact tip secured to said inner member beyond the end of said outer member and insulated from the latter, a Wire heating' element surrounding and insulated `from said inner member, one end of Asaid Wire being' electricallyv conneeted to Said inner member adiaeent seid bloei; and the other end to said tubular v*member adiaeent its outer end.
