8 Claims.

This invention relates to the method of and apparatus for waving hair and is. more particularly directed to a method of and apparatus for producing permanent waves in human hair.

An object of the invention is to provide apparatus in the form of an improvement upon prior devices in which rotary spindles are employed upon. which hair is wound as a preliminary step in the method of producing a curl by the action 0f vapor and heat, the construction of the improved apparatus being such that the hair when wound upon the spindle means employed will consist of respective wound portions of more nearly corresponding amounts than was heretofore possible,.evenly distributed upon the spindle and firmly pressed against the hard external surface thereof, so that the wave will be structurally the same. at all places from the tip of the strand to the scalp and of a higher degree of permanency.

The invention is particularly directed to the class of hair curling apparatus in which the waving of the hair is done by the Croquignole method. In such methods, a fiat strand of hair is wound upon a curling spindle parallel to the scalp, the tip of the strand forming the innermost portion of the windings of the hair and being disposed at the centerof the spindle. The hair is then tensioned circumferentially and retained in a ten.- sioned condition until other steps of the method have been completed. Because of the external form of the spindle and considering the manner in which the hair is waved, it follows that the greatest number of wound portions of the hair will come at the very center of the spindle. In consequence thereof, a cushion is unavoidably formed beneath the outermost wound portions of the hair, making it impossible to place substantially equal circumferential tension upon the re- 1 spective wound portions. As a result thereof, the degree of permanency of the wave is often of a very negligible extent.

It is, therefore, an important object of the invention to provide a spindle which, when used with my methodfwill prevent formation of the aforestated hair cushion and enable all wound portions of the hair to be placed substantially under the same amount of circumferential tension and disposed very close to the hard surface of the spindle. By thus equalizing the tension upon all wound portions of the hair and disposing said portion close to the hard surface of the spindle,

the axes of which may be either coincident or parallel relative to each other.

A further important object of the invention is directed to use of means by which a flat strand of hair will be divided into substantially equal parts for use in the production of a corresponding number of curls;

A still further object of the invention is to provide means for dividing the strand of hair into substantially equal parts and disposing same for convenient combing and straightening thereof preparatory to winding same on the spindle means.

Another object is to provide means for apportioning or dividing the hair into substantially equal parts, then correlating same with a clamp having spindle means, the form of said hair apportioning or dividing means being such that it will have yielding engagement with the scalp and will not be uncomfortable to the person whose hair is being treated and will serve to protect the scalp from the severe elTect of heat during the application of heat to the hair in the steaming process. Such steaming treatment is for the purpose of evaporating the moisturefrom the hair or from moisture pads, and thus effecting final setting of the curl, as is well known in the art.

Other objects and advantages will unfold themselves upon reference to the following description and the accompanying drawings, in which Figure l is a View in perspective showing the first step in preparing the hair for passage of same through the strand dividing element;

In carrying the invention into practice, use is made of a hair waving clamp 20, preferably, but not necessarily, like the one disclosed in my copending application Serial No. 16,493, filed April 15, 1935, the same having rotary spindle means 2 I, mounted at its ends to turn in brackets 2222 which form parts of the clamp. Except with respect to certain features, the spindle is substantially of well-known construction and is provided at one end with a ratchet wheel 23 adapted to co-act with a holding pawl 24 at one of the brackets 22, whereby hair when wound upon the spindle can be held under desired circumferential tension.

While I show one form of spindle upon which the hair can be wound when practicing the method which I will describe hereinafter, the single spindle can be replaced by two spindles the axes of which are parallel to each other, or I may even use two similar short length spindles which are co-axially related to each other. Whenever resort is had to the use of separate spindles, it is to be understood that one thereof will receive one-half of the total amount of hair comprising a strand and the other the remaining one-half of said total amount of hair.

So far as the steps of the method are con- .cerned, same can be practiced with the use of any well known form of clamp, except that the form proposed or suggested to be used will, I believe, produce better results. The invention will, therefore, be considered within that range of use of known clamps that will best serve the main purpose in view. I

In combination with the aforementioned clamp, use is made of a strand dividing or apportioning element. 25 by means of which equal division of the strand is effected and the separate parts or sub-strands co-ordinated with the clamp and disposed to enable same to be wound thereon and thus produce distinct or separate curls. Dividing the whole of a single flat strand into two equal parts would seem to be sufficient, but it is to be clearly understood that more than two can be provided for, if desired. The main thought being conveyed is that more than one curl is formed by my method in a single winding operation of the same strand of hair. This is the dominant feature of the invention, and has never before been done, to the best of my knowledge. Said element 25 consists of a substantially rectangular piece of soft, pliable and preferably stretchable material, such as a suitable grade of sponge rubber or the like, although felt or even a good grade of cork or the like may be used with fairly good results. To give it a desired measure of strength and reinforcement to the element,.I provide flexible strips 26 of fiat material such as celluloid or the like which can bend or flex readily and will be moisture repellant. The element 25 is formed with a slit of peculiar configuration which passes entirely through the material of the element from one alined long stretches 2'|2T and a substantially intermediate portion 28 of substantially inverted V-form. From the very nature of the material of which said element is formed, it follows that the normally closed resilient slit can be expanded manually to enable a strand of hair to be threaded therethrough. The inherent resiliency of the material is such that the slit tends to take a fiat purchase against the strand of hair. The construction of the slit is further such that the intermediate portion of the lower wall thereof (when viewed as in Figure 10) is provided with a hump, gate or barrier 29, the purpose of which will be explained when the steps of my improved method are described in the following description.

So far as concerns certain structural features of the various mechanical parts employed, it will suflice to say that the clamp has parallel jaws 30 and 3|, the effective hair gripping faces of which have longitudinal strips of elastic material 32 and 33, provided with wide width sealing and gripping flanges 34 facing toward the spindle 2| and short width flanges 35 facing toward the front of the element 25. The element is about co-extensive with the length and breadth of said element and the slit in the element is disposed to co-incide directly with the effective clamping faces of the jaws of the clamp 20. The spindle 2| has a stem 36, the longitudinal curvature of which from one end of the spindle is slight as compared with more or less common forms of spindles.

As the hand plays an important part in carrying the method into effect, and as the method can be practiced in more than one known way, ,I shall claim the method as well as the device per se and its adjuncts. The method will be described as follows:

A suitable amount of hair to constitute a strand to be treated is first combed to render the strand even and flat as shown in Figure 1, at which time, or following the initial combing, (i. e., after the clamp is applied) the hair is treated with the customary treating solution or solutions, such as water, bi-carbonate of soda and carbonate of magnesia. The tip of the strand is then threaded through the slit in the element 25 to be equally divided among the long stretches 212'! of the slit, and the soft side of the element moved to closely contact the scalp. The barrier 29 holds the equal portions of the strand at the respective sides of the hump, as clearly-illustrated in Figure 2, at which time the gripping faces of the slit will be in perfectly flat engagement with the hair. The respective portions of the strands are now preferably re-arranged and carefully straightened by combing, while the tips of said portions are held between the fingers of the hand. The clamp 20 is then applied as shown in Figure 3, so that the wide width flanges 34 will be brought into firm gripping engagement with the hair and the respective portions of the original strand sealed between said flanges to prevent escape of moisture and objectionable hot vapor through the jaws in the direction of the element 25 and scalp of the head.

When the clamp 20 is fully applied, as last stated, thetip ends of the equal amount parts of the strand are made to overlap each other by manual manipulation and by pinching or holding same between the fingers of the hand. Said equal parts of the strand are now diagonally disposed relative to each other and the tips thereof are placed at the very center of the spindle and wound turn upon turn upon said spindle, as shown in Figure 4. I have previously stated that the spindle has but a very slight longitudinal curvature, and we can assume that when the hair has been wound upon the spindle to the extent shown in said Figure 4, the intended extent of the winding has been completed for this much of the longitudinal area of the spindle. The hair now wound as just statedis in the form of a short cylinder and all of its wound portions or turns reside very close to the hard external structure of the spindle, to thus avoid formation of such bulk of hair as would result in the production of an objectionable'hair cushion beneath the outermost Wound portions. In this manner uniform tension can be placed on each turn of the hair. With these steps performed, the remainder of the respective fiat portions of the strand is wound upon the spindle, the fingers of the operator manipulating the hair to maintain a more or less parallel condition of said portions while winding same upon the spindle and exerting lateral feeding stress thereon to lay same evenly on the spindle progressively toward the extreme ends thereof. When the whole of the winding operation has been completed, the hair can be circumferentially tensioned to the desired degree by turning the spindle and holding same against retrograde rotation by the escapement means of the clamp. The hair in its fully wound condition now has the form of a cylinder and the wound portions of hair are more or less uniformly the same as to total mass or quantity at each place in the spindle, and the respective wound portion will be under substantially the same tension. In consequence thereof, the wave resulting from final treatment will consist of not only two distinct curls but will have a much higher degree of permanency than has been possible heretofore.

After the hair has been wound upon the spindle means. 21, it is encased within a heating chamber such as the one shown in my Patent No. 1,965,156, dated January 30, 1933. After the hair has been subjected to the action of heat over the required period of time, same is removed from the spindle means in the customary manner and the treatment of the hair continued also in the usual manner.

If desired, a spindle such as shown in my Patent No. 1,895,815, dated Jan. 31, 1933, may be used, except that its longitudinal curvature will conform to the conditions herein explained. In such form of spindle, means are provided for causing the vapor as it is generatedat the hair to be discharged from the chamber. A spindle of this character is preferred to one in which means are not provided for rapid escape of the vapor. However, this is entirely discretionary and has no particular bearing upon either the method or certain structural features of the invention.

In my prior Patent No. 1,895,815, a moisture pad 38 is employed and adapted to be placed in the heater which encloses the spindle during the heating treatment. Such pad may of course be used to advantage in practicing the invention herein disclosed.
