T. R. JUDD HAIR WAVER Dec. 9, 1952 Filed May 28, 1951 lNL/ENTUR THEE-5A R. JUDD ATTURNEY Patented Dec. 9, 1952 UNITED STATES PATENT OFFICE HAIR WAVER Thresa R. Judd, Portland, Oreg. Application May 28, 1951, Serial No. 228,683

1 Claim. 1

This invention relates generally to the art of hair dressing, and particularly to a hair waver.

The main object of this invention is to produce an inexpensive, simple, and eflicient form of hair waving apparatus by means of which an inexperienced operator may satisfactorily produce what is known as a paper wave.

The second object is to produce a device of this class which will employ electricity for heating purposes and which will operate at a very low voltage, and in which the temperature is maintained at a point below that at which the hair or skin of the user can be injured thereby.

The third object is to construct an apparatus of the class described which can be easily manufactured, assembled and disassembled, and in which the parts are readily accessible for oleansing and replacement.

These and other objects are accomplished in the manner set forth in the following specification as illustrated in the accompanying drawing, in which:

Fig. l is a perspective view showing the device in operation.

Fig. 2 is a side elevation of the device.

Fig. 3 is a plan.

Fig. 4 is an end elevation of the device with a portion broken away in section with the support Hi removed.

Fig. 5 is a section taken along the line 55 in Fig. 2.

Fig. 6 is a view showing a group of discs in one of the heating elements as they are about to be assembled.

Fig. 7 is a diagrammatic view of the electrical circuit.

Similar numerals refer to similar throughout the several views.

Referring in detail to the drawing, there is shown a clamp consisting of a pair of opposite arms I and H which are channel shaped in transverse cross section and are provided between their ends with ears [2 through which extend the pivot [3 of the rubber covered head rest I4 whose end l projects through the opening IS in the member ID.

The outer ends of the members and II are secured to the heating elements themselves. Each heating element consists of a circular disc i! which is provided with perforations I8 for the lead wires 19 and 20.and a counter-sunk center opening for the screws 2| by means of which it is attached to its respective members 10 and H.

A plurality of mica discs 22 are placed against parts the disc H to insulate same electrically and thermally. A heating element in the form of a resistance coil 23 is disposed within the mica strip 24 and is connected to the lead Wires [3 and 20 which pass through the holes 25 in the discs 22. Mica disc 26 is placed against the mica strip 24 and then the members ll, 22, 24, and 28 are placed within the cup shaped pad 21 Whose edges 28 are then curled inwardly to confine the disc ll making the heating pad 21 an integral unit.

The pads 2'! are disposed on opposite edges 28 with their faces 29 urged toward each other by means of the spring 30 which is disposed between the ends 3| of the arms l0 and II. Finger buttons 32 ar mounted on the ends 3|.

The leads [9 are connected in series by means of the flexible wire 33 while the leads 20 are connected by the wires 34 and 35 to a suitable source of electrical energy 36 which may be in the form of a battery or a generator. In common practice it is desirable to keep the voltage as low as possible making it usable for 32 volt systems used in farm lighting equipment or for use in six volt automotive electrical systems. Obviously, if a device of this character is to be employed where only higher voltages are available, a suitable transformer (not shown) must be used. It is desirable to provide a switch 31 in the wires 34 and 35 for the control of the device.

In the operation of this device the hair is first wound upon a suitable form which is then withdrawn and the curl of hair 38 is placed between the folds of paper 39 which is then placed between the heating pads 21 which are moved apart by manual pressure against the buttons 32, the release of which causes the pads 21 to hold the paper covered curl 38 under the pressure of the spring 39 at whatever temperature is permitted to develo in the pads 21 by reason of the character of the heating element 23 and the voltage employed. The device is then permitted to remain suspended from the hair of the customer with the rubber head rest l4 resting against her head, as shown in Figs. 1 and 5.

While the heat is being applied, the next curl is being prepared. Obviously, more of these devices can be employed if desired, the number being controlled by the speed of the operator in forming the curls and the length of time it is desired to permit the curls to remain between the heating pads 21.

I claim:

A hair waver comprising in combination a pair of elongated channel-shaped, oppositely-turned 3 arms having the open sides of said arms facing each other, said arms having intermediate ears formed thereon having a pivot wire extending through said ears to permit said arms to rock on said pivot wire, one end of said pivot wire being inturned laterally to form a two-point support transversely of said arms, the extreme end of said support being anchored in a hole in one of said arms, a cup disposed on each of said arms and secured thereto, finger buttons on one end of said arms having a spring therebetween and a low voltage heating element in each of said cups comprising a mica strip disposed within each of said cups having a resistance element wound thereon, a flexible connection between the ends of said elements nearest said finger buttons and means for supplying current to said heating elements.
