ELECTRIC i HAIR GUREER.
Application rfiled .Tuly 7,
My present invention is an electric hair curler especially designedfor the waving of hair andsuitable for the production of vthe so-called marcel, or other waves; and it is an espectial object of this invention to provide an electrically heated hair curler of advantageous form with effective and durable heating means. All parts of my hair curler are capable of being manufacturedand -assemble-d at moderate cost, although not easi ly liable to accidental breakage or derangenient.
My invention comprises an electrical heat-` t ing element of noveldesign adapted to be incorporated in what may be termed a harnnier or T type of hair curler; andit comprises alsor an advantageous exterior or ernclosing shell construction comprising asplit or two-part casing'held/ together at two or more points by clips or ferrules, some of vwhich may be in the form of caps, although one ofsaid clips orvferrulesmay be the. upper end of Yan insulating hollow handle through which the lead vwires to said heatingk Other objects of my invention will appear f from the following description of alternative emcodiments thereof, `taken in connection with the appended claims andthe accompanying drawings, in which- I A Fig. 1 is an elevationalview of the head orcurler end of a heater of my improvedv design, with a strand of hair wound thereon.
Fig. 2 is a longitudinal section through aA heater of the same type. t
Fig. 3 is an additional longitudinal section, which may be regarded-as taken in the planev indicated by the line 3-3 of Fig. 2. w
Fig. 4 is a top plan view taken inthe direction indicated by the arrow 4 of Fig. 3,` the parts being broken away. .t
Fig. 5 is a transverse sectional view taken as indicated by the line 5-5 of Fig. 3.
Fig. 6 is a separate illustration of -an alternative type of heating element hereinafter referred to. Y
Referring to the details of that specific embodiment of my invention illust-rated in Figs. 1 to 5 inclusive, the heating element 11 of my hair curler may be housed within a substantially T-shaped casing or shell, preferably formed in two sections 13 and 14, these sections being shown as held together by clips or ferrules comprising caps 15, 15, and optionally comprising also the 192i. seriai'No. 724,557.
The heating element 11 ymay be of'any usual .or preferred. design, but I consider it especially advantageous to forni the same by winding acomparatively line resistance wire, such asa nickel chromium wire 19, in suitable spaced grooves 20, such as spiral grooves, formedr in the exterior surface of an insulating body, the said insulating body being shown as provided with shellsspacing projections inthe form of terminalflanges 21, 21, shown as provided with notches 22, 2.2V through which an Iend of the .resistance wire may be. returned by way of a substantially Acentral longitudinal channel 23to 4which extends a lateral opening 24 4to per-.
mit the connecting of the fre-e ends of the wire 194 with the main conductors 18, 18.l
Any usual orppreferred connecting means maybe employed in securing the ends ofthe resistance wire 19 to the main conductorsl18,
18'; `and my,preferredmeansdfor this purpose may comprise conductive leads 25, 25, having flat ends deformed to providechannels 26, 26 adapted to'be crimped about both the ends of the main conductors 18, 18".` and the extreme ends of the resistance wire 19 wound looselypon theleads 25, Y25.
the mentioned spacing of the-heating element V11 from they surrounding shell by Although air-insulation,as provided by l,
means of the flanges 21, 21, may be relied upon effectively to insulate the wire 19 from theV surrounding casing, l may` optionally employ in the head of my electrical heater additional insulating orspacing means such asmica plates 27, 28; and the insertion oft these may be especially desirable whenth'e insulating bodyv of myheating elementV isV substantially semi-circular` in cross sectional outline, as best shown in Figs. 3 and 4. The
insertion, of insulating materials in the' transverse bar of the 'shaped head member may, however, be entirely dispensed with, by, for example, the employment of an insulating spool of the character best shown in 4ig. 6, this spool being substantially circular in cross sectional outline, although provided with a longitudinal channel 27 extending to the slots 22"', 22a in the flanges 21g, 21a by which air-spacing is effected, the ends of the insulating wire 19a being carried out through a lateral opening 24a and optionally connect-ed substantially in the manner already described.
Insulating cores 29 or 29a of the characters disclosed in Figs. 2, 3, 1 and 6 mayadvantageously be cut from a material such as lava; and this saine material may advantageously be employed inthe stem 30 of a T-shaped head of the character described, separate longitudinal channels 31, 31 being shown as provided for the respective conductive leads 25, 25', and any desired means such as a screw or screws 32, 32, being employed to connect said stein with the upper end 16 of the handle 17, or its equivalent. rThe main conductive wires18, 18 may advantageously be carried through the handle 17 in separate insulating tubes-33, 33; and a connecting plug 3-1, provided with conductive pins 35, 35 connected with the main conductors 18, 13, may be spaced from and secured to the stein 30, or its equivalent, by means suoli as an assembly plate 3G, shown as secured to'the insulating plug 34E by means of a band 37, the mentioned screws 32, 32 being preferably carried not only through the respective sections 13, 14 of the shell compris-ing the stem 30, but also through the upper end of said assembly plate.
Although, I have herein ldescribed all structural details of a complete hair curler device, it should be understood that I attach especial importance to the described construction of the heating element 11, including the alternative forni 11CL thereof shown in F ig. 6, and to the three-point clip construction by which I may hold an outer casing in insulated relationship thereon. To prevent accidental or unauthorized removal of the caps 15, 15', or their equivalent, they may advantageously be crimped or otherwise deformed in place, substantially as indicated at 38, 33v in Fig. 1.
Although I have herein described one complete embodiment of Vmy invention and an advantageous alternative construction of a heating element suitable for use therein, it should be understood that various features described might be independently employed, and also that various modifications might be made, by those skilled in the art, without the slightest departure from the spirit and scope of my invention, as the same is indicated above and in the following claims.
' within said casino" I claim as my invention:
1. An. electric hair curler comprising; a T-shaped head consisting of a closed hollow shell having a stem; an insulator entirely enclosed within said shell; an electric heating element wound on said insulator; a hollow handle associated with said stem of the head and communicating therewith; and connecting means for said heating element comprising circuit conductors connected to said element and extending from said shell directly into the hollow stem and handle.
2. A heater as described in claim 1 in which said shell is split in a plane extending through the bar of said head.
3. A heater as described in claim 1 in which said shell is split in a plane extending through the bar of Vsaid head and in which the sections of said shell are held together by neans engaging the ends of the respective sections.
.11. A heater as described in claim 1 in whichsaid T-shapcd head is held together by means comprising caps at the ends of the bar thereof.
5. A heater as described in claim 1 in which said `l'-shaped head is held together by means comprising caps at the ends of the bar thereof and comprising also an endV of the insulating handle through which conductive leads extend.
G. In a haircurler: aic'asing; an insulator b 7 ment wound on said insulator; connecting means for said heating element comprising leads of'conductive material channeled at one end for crimping, the ends of said heating element being wound about said leads and held in conductive Contact with said leads by the crimping of said channeled ends; a longitudinally grooved insulating element within which said leads are spaced apart; a handle through which said lead conductors extend; a connecting plug near one end of said handle; and an assembly plate provided with means for securing the same within said handle.
7. In an organization as described in claim 6, a two-part T-shaped shell surrounding said heating'elementand held in assembled relationship partly by insertion in said handle.
In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 28 day of J une, 1924. l
