Aprim'ary object of thisinvention is to provide a method and means for permanently waving hair which will eliminate the so called setting operation, after the waving operation, which is,

my in virtually all permanent waving sys-, 1n heretoforeknoWn;

whether the wave is imparted by means of electric resistance heat, heat from an exothermic chemical reaction, or by so-called cold waving imparted by a chemical treatment of the hair without the use of heat, after the wave is imparted, each waved tress must be removed from the curler around which it is wrapped, and then re-set or styled into the form in which it is to be worn. This involves setting the tresses into difierent formations than those in which the wave was given.

By use of the present invention this series of steps is eliminated so that when the curls are formed and processed the desired curls and styling are formed and determined in one operation. Thereby the setting operation ordinarily necessary is eliminated.

Generally-in using the devices of this'invention in permanent waving-a tress of hair is wound-u which is preferably innit-ed iournaiedrelation to a base or di'se' member which is re= silint 7 and' slotted. After "being wound in coiled form on' the spindle almost td'the scalp, the -p'rox imal portion of the-* tressis p'as'sed th'rough theslotted" p'brtion' of" the di's'c -and' thespindle bear ingthe coil of hair is their rotated with" respect? to the disc" tensioning" the tress andforci-n'g the dis'cjagainst-the scalpr- 7 Referring n'ow' ii'i 'd'etail to the accompanying? idrawings, Figure 1 shows' a spindle i having a long-itiidinai'slot-fi Said spindle is journaled 'ima disc havingja slott termin'ati'ng in an enlargediinnenporti'unt.

Preferably the spindle l'is-iformed ofarelatively' Q- rigid material such as a thermosetting' resin,

while the -di'sd 3"is "made of aflexible resilient material such as-rubb'er. The spindle, in the"em-- bodimen't of Figures. 1 and 2 has near one end thereof a pair of flanges} 'I a'nd Bi The distance between said flanges is=less than the normal is attached to said spindle I, the portion of the disc positioned between said flanges and 8 will be compressibly retained. Such a structural rela tionship will maintain the spindle and disc in normally fixed relation, yet will permit relative movement under cooperative frictional restraint.

Flange 1 is preferably beveled oil so that when the disc 3 is in contact with it and flange 8 the periphery of the flange 'I and the adjacent surface of disc 3 will provide an uninterrupted surface so that when a tress of hair is wound on the device it will be diflicult for any random strands of hair to be caught between the flange and the disc thereby tending to result in a more perfect wave and eliminate a possible source of discomfort to the recipient of the wave. To further this purpose, flange 8 is preferably of a smaller diameter than flange 1. Additionally such disparity between the diameters of said flanges will facilitate assembly of the spindledisc structure.

Figure 3 shows the distal end II of a tress of hair I0 placed in the slot 2 of spindle l in the initial step of the winding operation.

The tress is then wound on the spindle toward the proximal end of the tress until the device is quite near the scalp. The proximal portion of said tress I0 is then passed through the slot 4 to its enlarged inner portion 5. The disc is then held against movement and close to the scalp while the spindle I is further rotated with respect to the disc so that the remainder of the tress I0 is wound and tensioned. on said spindle, forcing said disc 3 against the scalp, as shown in Figure 4, where it is retained until the waving action is completed.

Figihe 5 is an alternative embodiment of the invention showing a, spindle l5 adapted to rotate about a flanged bolt It which is attached to a disc member [1, by a nut I8.

Said bolt IS when tightened with respect to said nut compresses said spindle [5 in frictional bearing relationship against said base member I1. the base member I1 has a slot 2| terminating in an inner enlarged portion 22, which are equivalent to the respective portions flange 1 and slot 4 and inner portion 5 of Figures 1 and 2.

The devices and methods of this invention are particularly adapted for use in the cold permanent waving methods which customarily are given in the form of Croquignole waves with the customary waving and neutralizing lotions known in the art. In such cold waving this invention has an additional advantage that after the waving lotion has acted on the tress under tension the spindle can be somewhat loosened to relax the hair during the neutralizing step to facilitate complete penetration of the tress, particularly that portion closest to the spindle. The tress can again be re-tensioned if desired." The waving solution may be applied to the tress before winding, as in so-called wet winding, or after the winding is completed.

Such control of the tension of the curl on the spindle permits accurate control of the tightness of the curl ultimately imparted. Therefore, a head of hair may be waved in a predetermined pattern, with the'elimination of the usual guesswork about the outcome. Consequently as one style is sketched or otherwise indicated by a hair stylist, the wave may be competently given by a relatively inexpert operator.

When the devices of the invention are used in exothermic machineless waving it is necessary,

Said spindle has a flange member 20, and

4 of course to provide a protective insulating sheet, as of felt or the like, between the curler and the scalp to protect the scalp from steam or condensate from the chemical reaction of the machineless waving pads.

Naturally, in this type of waving, the spindle would not be made of plastic material but prefer ably a metal such as a light aluminum alloy.-

Other means than those illustrated and described of providing the operating relationship between the spindle and the base member of normally fixed but relatively rotatable connection will be apparent to those skilled in the art.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claim without departing from the principles of the invention and without sacrificing its chief advantage.

What is claimed is:

A device for winding a tress of hair preparatory to permanently waving the same, said device comprising a flexible resilient disc having a through opening and a slot which extends inwardly from the periphery of the disc, and an elongated slender rigid spindle consisting solely of a rod-like member having its lower end frictionally received in the opening in the disc and having a pair of flanges frictionally engaging opposite faces of said disc whereby said disc and spindle normally will rotate together and said spindle can be rotated relatively to said disc under frictional restraint, said spindle having a slot for engaging and retaining an end of a tress.
