PERMANENT WAVE DEV ICE Filed July 3l, 1954 /NVENTOR ROBERT BRAUNAGEL By /M/riQ- ATTORNEYS Patented Aug. 18, 1936 UNITED STATES PERMANENT WAVE DEVICE Robert Braunagel, Victoria, British Columbia, Canada, assigner to Wireless Electric Supplies Limited, Vancouver, British Columbia, Canada Appiication July 31, 1934, Serial No. 737,799

1 Claim.

My invention relates to improvements in permanent wave devices, the objects of which are to provide means whereby the tips of the hair are set more completely than that portion of the hair which is close to the head; to provide means whereby the danger of scalp burns is avoided, and means for producing hair waves without inconvenience or discomfort to the customer.

The invention consists essentially of a spool and a casing therefor, and means for heating the spool internally, as will be more fully described in the following specification and shown in the accompanying drawing, in which:-

Fig. 1 is a sectional view of the invention assembled.

Fig. 2 is a sectional view of the hair spool.

Fig. 3 is a plan view of the end cap.

Fig. 4 is a sectional View of the heating element.

Fig, 5 is a plan view of the casing.

Fig. 6 is a sectional view of a preferred heater.

Fig. 7 is a general View of a clip for the heating elements.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral I indicates a metallic spool consisting of perforate tube 2 surmounted by a cone 3. The tube 2 is fitted with a hinged bar or clip 4, which is preferably curved outwardly as shown, to afford a grip of the hair wound around the tube throughout the length of said tube.

The numeral 5 indicates a cap of Bakelite or other substantially non-conducting material, which is provided with a recess 6 for the reception of the free end of the tube 2 and the clip 4.

The numeral 'I indicates a casing formed of two halves 8 and 9 connected together by a spring hinge I D of any suitable type adapted to hold the halves together in cylindrical form, and are provided with ears II by which the casing can be gripped and opened. The meeting edges of the side walls of the casing are slightly cut away to form a gap I2 through which the hair may pass.

4' The halves 8 and 9 are provided at one end with internal flanges I3 and one of said halves is provided at the opposite end with a pivotally mounted lid I4 which serves to close the casing 50 and retain the spool and associated parts therein. The halves of the casing are lined with a suitable non-conducting material I5 to retain the heat therein, one of said halves having an aperture I6 in its side wall, the purpose of which will hereinafter appear.

55 The numeral I1 indicates a heating element, see Figure 4, which consists of a soft metal rod such as copper or aluminum, having at its upper end a head I8 by which it can be lifted and placed in the spool I by means of a suitable clip, such as a pair of curling tongues I9 having a grip 28 at its free end, as shown in Figure 7. The upper end of the rod Il is embedded. in a block 2i of 5 refractory material of such shape as to t the cone 3 of the spool I and is covered with a washer 22 of non-conducting material.

The numeral 23 indicates an electric heater having a plurality of recesses, each adapted to 10 receive a heating element Il to impart thereto the heat required for the waving process.

The process of waving consists of taking a quantity of hair and wrapping it around the tube 2 of a spool I, securing the rst few windings 15 by closing down thereon the clip 4 and holding the clip in place by fitting to the tube an end cap 5, the tube is then wound into the hair until it is close to the head, when a casing l is clipped thereover. A heating element Il is next inserted into the spool and the lid I4 closed upon the casing to retain the heat therein.

If the hair is to be treated with compounds, a soluble compoundis placed in the tube 2 before the hair is Wound onto it and after the spool 25 has been enclosed in the casing l, a solution may be forced into the hair by a suitable spray jet inserted through the aperture I6 in the casing. The heat from the heating element causes the solution in the tube 2 to melt and permeate the 30 hair surrounding it, and any vapours generated in the casing are enabled to escape freely through the aperture I5, thus preventing it from passing downwards through the gap I 2 and eliminating the danger of scalding to the customer.

By virtue of the use of a preheated element, the temperature within the casing is at a maximum at the commencement of they treatment and must necessarily become less as the treatment continues, therefore, inattention on the part of the operator cannot result in harm to the customer.

What I claim as my invention is:

A hair Waving device comprising a cylindrical perforated member adapted to be covered with hair, an enlarged open ended extension` to the member, a metallic rod having an enlargement at one end, said metallic rod and enlargement being adapted to be preheated and wholly1 inserted intothe cylindrical member and its eX- tension and a casing for enclosing the cylindrical member and its extension, said casing having an end closure adapted to cover the enlargement of the metallic rod and hold it against endwise movement in the cylindrical member.

ROBERT BRAUNAGEL.
