I-IAIBDRESSING- APPLIANCE.

. Application filed November 17, 1923. Serial No. 675,423.

This invention relates to hair dressing ap pliances of the curling-iron variety that are heated by electrical energy. The particular device here considered is designed to otter dual pronged arrangement'especially applicable for producing an undulating or The objects of this improvement are to construct an electrically heated article that may be handled with safety by arranging the current connections between the Service line and an electrical resistance coil in a manner that willprevent excessive heat from passiiig into a handle portion. Also, in pro vidiiig an appliance that will permit of winding the hair in a figure-3 form about a pronged element and allowing the with- 'd'rawal of the said element without disturbing the figure-8 arrangeinentwhich isafterwards intentionally disturbedito produce the ultimateTelf'ect. Afurth'er object is, to devise'air assemblythat be put together readily and avoid complications in manufacture with a View to lessening the costs attending the production of devices of this kind which are intended to reach the purchaser at a low retail charge.

Other advantages may be noted in the following description referring to the accompanying drawing which is part of this application.

Fig. '1 is a broken sectional View of the device;

Fig. 2 an enlarged view of the wire splicmg here adapted;

Fig. 3 a section on line 3-3 of Fig. 1;

Fig. 4L a fragmentary view of the hair winding method;

Fig. 5 a modified form for housing the spliced portion.

Similar characters of reference apply to like parts throughout the several views.

A. handle H is centrally drilled to provide a major bore in and a minor bore h for admitting therethrough a service cord C of the duplex variety having the negative and positive wire 0 and a. The handle H widens into a rectangular pad H to coincide with a block B to which the said handle .is attached by means of the screws ss. The block B is recessed to offer a cavity or chamber Z) for accomodating the bulky splicing between an electrical heating means, to be later described, and the aforesaid cord C.

Tightly embedded in the block B are a pair of tubular prongs P whose tines may be of shorter lengths for such as bobbed hair, i

this feature is indicated in dotted lines as p on Fig. 1. The said prongs being hollow are spun at the outer ends to provide the smooth and blunt points T which readily enter the hair and allow of easy withdrawal therefrom. Within the prongs an electrical resistance wire 1 is inserted the entire length of the prongs in order to provide an even heat throughout the area over which the hair iswound. The resistance 1 connected, by the aforesaid splicing, to the cord C' with which it forms a continuous circuit that leads from the wire 0, into and out of one tine, crosses through the chamber 6 and similarly enters the other tine thence out through wirec, as is clearly shown in Figs. 1 and 2. a j

F 2 shows in detail the connection adapted here for electrically stepping from the heat of the resistance means, or coiled wireto the normal service cord, for stopping the excessive heat in the said resistance wire from passing beyond the chamber 6. This step is attained by wrapping together the pull upon the said cord, by virtue of the shoulder K, from disturbing the splicing J which is finally embedded in a heat resisting mass within the aforesaidchamber b.

' Fig. +i illustrates how the hair is placed about the prongs and pushed along same until the desired amount is laced thereon when the current is turned on for a period of time after which the device is removed and the strands of hair unfolded by hand to arrange the desired eii'ect.

F 1g. 5 IS a modified form of housing for the spliced portion described above, and I consists of a vertically split bakelite black B oppositely cored at b and encased in a shell S that embraces the handle H to which it is securely attached by suitable screws or rivets 5 located at either side of the bore it. The b-akelite element in this modified form leaves the asbestos yarn an unnecessary precaution for guarding against the high temperature that occasions the adaptation of the said yarn in the first described method. The said Fig. 5 shows an alternative method of providing individual tips T for acquiring the blunt ends of the prongs, here indicated as P.

Having described this invention what is desired to protect by Letters Patent is:

1. A hair dressing appliance having, a counterbored handle attachable to and registering with a chan'ibered block, said block forming a spacing base between dual prongs and the said handle, the block aforesaid adapted to contain heat resisting material in which is embedded current conducting wires that pass from said handle and the prongs aforesaid. I

2. in a hair dressing appliance the combination of, a counterbored handle and tub uiar prongs, electric wiring means for heating the said prongs, a bifurcated spliced jointure v for retarding the heat of said means from passing back into the handle portion, an intermediate chamber for housing the bifurcated spliced union between the handle aforesaid and the prongs, and a heat resisting material embedding the bifurcated jointurc within the chamber aforesaid.

A hair dressing appliance having, an intermediate block member for uniting a pronged portion with a handle portion,

chambered means in said block for maintaining in bifurcated relationship the jointures connecting a service wire to a heating clement.

l. 1; hair dressing appliance comprising a: pronged portion and a handle portion having, an electric element and a heating element bifurcated and bound together by a metallic medium of less resistance than either element aforesaid, heat resisting windings about the jointures so formed, said jointures disposed within an outer covering that is extended beyond the jointurcs to increase the thickness oi said scrrice cicmentto a diameter that exceeds a reduced bore in the aforesaid handle portion.

In a hair dressing appliance the com-- bination of, a handle portion, a pronged portion, an intermediate element of heat resisting properties arranged to provide bifurcating grooves that function as leads to dual passages in the aforesaid pronged portion and to a singular passage of varying diameter piercing the aforesaid handle portion.

In testimony whereof we aflix our signatures.
