March 28, 1939, Serial No. 264,580.
April 4, 1938 Claims.
This invention relates to the art of beauty culture and particularly to improvements in hair waving apparatus in which pre-formed locks of hair are subjected to heat generated by an exothermic compound so as to cause a permanent wave to be set in the hair.
This application is a substitute for the application which was filed on December 22, 1936, known as Serial No. 117,133 for a Permanent hair waving apparatus, and which application was abandoned on the 7th day of May, 1938.
In the art of curling or waving natural human hair, it has been the general practice to; first, moisten or treat the hair with a hair setting liquid, usually ammonia, or with a saline solution such as borax and water; second, to coil a lock of treated hair around a spindle of the desired shape, and; third, to apply heat thereto for.
definite periods of time. The heat causes the steam from the hair setting solution to enter the hair cells, which expand and cause the hair to become wavy.
Of the various methods of applying the necessary heat, electricity is the most commonly used. The external application of steam is also used to cause the hair setting solution to vaporize. A third method in common use, utilizes a pad containing chemicals, which when moistened after being wrapped around a pre-treated lock of hair, activates or re-acts sufficiently to create the necessary heat.
I have found that when air is mixed with a vaporous organic hydroxide such as alcohol vapors the gas formed is highly combustible and may be ignited or engendered by the mere presence of a metallic catalytic agent, such as platinum or palladium. It is to the application of a vaporous exothermic compound engendered by a metallic catalyst, for the purpose of creating heat in the waving process that my invention is particularly directed.
It is common knowledge in the art that excessive uncontrolled heat is apt to cause damage or injury, not only to the scalp, but also to the hair itself. Excessive heat may dry the hair to such an extent that it becomes brittle which causes the hair to take on a harsh, lifeless and bleached appearance. Insufficient heat on the other hand, slows up the operation considerably and decreases the permanency of the wave.
It hasbeen found that difierent types of hair and different kinds of hair setting solutions require correspondingly different temperatures and different periods of time for treatment. Of the various methods. utilizing chemical reaction for This application In Canada this purpose, prior to my invention, none of them were controllable during the operation. That is, the chemicals used for the exothermic reaction are packed with the lock of hair and the heat once pre-determined by the amounts of and the combination of chemicals could not be varied or controlled, neither could the hair be exposed and examined during the operation. The prior art devices allowed the chemicals to come in direct contact with the hair or scalp, often to the annoyance, if not actual damage or injury to the person.
It is, therefore, the main object of this invention to provide an improved and safer means and method for applying heat to hair curlers and.
wavers.
Another object is to utilize for heating purposes in a hair waving machine the phenomenon of slow spontaneous combustion of a vaporous exothermic compound, such as a volatile organic hydroxide, engendered by a metallic catalyst.
Another object is to provide a permanent wave machine with exothermic heaters that are free from moisture, obnoxious odors, and injurious chemicals, as well as, being light in weight and economical to operate.
A further object is to provide an apparatus of this sort with heaters that are speedily and easily applied and are fast in operation; that is, quick heating and quick cooling.
A still further object is to provide the wave heaters with automatic shut-off means, that will enable the operator to use less than the maximum number of heaters without waste of heat or loss of fuel.
Another object is to provide a permanent wave machine with heat controls that are exact in operation, and which are simple and easy to manipulate.
A further object is to provide apermanent Wave machine with removable heaters to enable the operator to, apply them individually andwithout the annoyance of attachedcords and cables, and also to permit them to be easily cleaned and. sterilized.
Other objects and features, and a practical embodiment of my invention are more fully set forth in the following description and claims, reference being made to the accompanying drawings in which like parts are designated by like reference characters, and in which:

In the Figure l, I show a base 2|, from which there rises pipes 22 and 23, and suitable supports 24. A manifold 25, is attached to the supports 24, and connected to the pipe 23. A plurality of heaters 5| and 69, are suspended from and connected to the manifold 25, by flexible tubes 26.
The base 2| contains a supply or a source of air 21, which may be either a simple blower or a tank of oxygen. The base 2| is also mounted on rollers 28, for convenience in moving the apparatus around. The supports 24 are rather substantial braces solid enough to hold the manifold 25 without straining the pipes 22 and 23.
The manifold 25 consists of a hollow chamber and may be of the general shape and design shown in the Figure 1. The manifold may be easily constructed of light metal, but the base 2| should be of cast metal heavy enough to make a rather solid and substantial foundation.
Approximately midway between the base 2| and the manifold 25 is a compartment 3|. This compartment contains a fuel container 32, a valve 33, and connecting pipes 35, 36, and 31.
The fuel container 32 is simply a small tank in which there is a wick or a loose cotton packing saturated with the liquid fuel. has been found to be a very satisfactory fuel for this purpose. A filler cap 46 is provided for the tank and it extends outside the compartment for easy filling. The tank also has an inlet for air 29, and an outlet for the exothermic gas 39, created therein.
The valve 33 is of a simple design and has for its essential feature the ability to control the volume of air 29, entering either the fuel tank 32, by way of the pipe 35, or entering the manifold 25, by way of the pipes 31 and 23. The elements comprising the fuel container 32, valve 33, and connecting pipe may be substituted with a carburetor similar to those used on automobiles for vaporizing gasoline. The carburetor I do not Methyl alcohol show in the drawings because its general construction and operation are well known.
On the outside of the compartment 3|, there is a governor or a control panel 38, on which there is an electric switch 4|, for starting or stopping the blower mechanism 21; a scale 43, calibrated for temperature degrees; a handle 44, which operates the valve 33, and a time switch 42, which after a pre-determined set period automatically opens the switch 4|, or which can be made to operate the handle 44, so that after the set time the valve 33 is turned to the cool position automatically.
The handle 44 is attached to the valve 33, at the shaft 43, and it also has a pointer 45, which is readable on the scale 43. This pointer 45 may be set for definite operating temperatures to suit a particular permanent wave solution, and the automatic time switch can be set to accommodate a particular type or texture of hair. For example a hair setting solution containing ammonia may have a low boiling point and a solution such as borax and water may have a comparatively high boiling point. Also coarse wiry hair may require a shorter heating time than soft fluffy hair. In any event excessive or unduly prolonged heat may remove the natural hair oils and cause the hair to become brittle. The operator can regulate the temperature and time to suit the setting solution used and the texture of the patrons hair by merely manipulating only the valve handle 44 and the time switch handle 40. The temperature range for setting normal and average hair may be easily controlled between F. and 350 F.
The diagrammatic illustration of the Figure 2 clearly shows how the exothermic vapors are created and controlled. The source of air 29 is constant during operating; that is, its volume and pressure once set remain the same for all operations. The air 29 travels up through the pipe 22, through the valve 33, then through the pipe 35, and into the fuel container 32, there it is mixed with the alcohol vapors. The resulting gas 39 travels through pipes 36 and 23, to the manifold 25, where it is distributed by means of the flexible tubes 26, to the heaters 5| and 69.
The heaters 5| and 69, which I will presently describe contain a catalyst 41, and when the gas 39 enters them slow oxidation takes place.
The resulting heat is controlled by the amount of air 29 allowed to mix with the alcohol vapors, and this in turn is regulated by the valve 33. To increase the heat turn the handle 44 counter-clockwise, and to decrease the heat or to quickly cool the heaters turn the valve handle 44 clockwise, or to the right.
In the Figure 3, I show the handle 44, at a point on the scale 43, marked 350 Fahrenheit. This position of the handle would correspond with the positions of the ports 48, in the valve 33, shown in Figure 2. In this view the maximum amount of air 29 is passed through to the container 32. Also in the Figure 3, I show alternate positions of the handle 44. In one such alternate position the pointer 45 indicates 200 Fahrenheit on the scale 43, and would correspond approximately to the position of the ports 48, as shown in the Figure 4. The other alternate position of the handle 44 points to cold on the scale. When in such position the valve port 43 would appear as indicated in the Figure 5. In the Figure 5, it will be noticed that only the air 29 would enter the manifold 25, and the heaters i and 69, without mixing with the alcohol vapors. With the handle 44 in this position-the heaters would quickly cool and prevent over heating of the hair. The operator also would then be able to handle the heaters safely and conveniently without the loss of time otherwise taken for normal cooling.
The Figures 6 to 14 inclusive illustrate the heaters intended for use with my permanent wave machine. The Figures 6, 7, and 8 show a type of heater used to fix a marcel wave commonly known as the Croquignole. The Figures 11, 12, 13, and 14 show a variation type of heater suitable for fixing a spiral curl.
The wave heater consists of a hollow concave metal chamber 5|, to which is rigidly attached a grip 52. Adjacent to the grip 52, is a lever 51, which is pivoted to the chamber by the pins 55. The lever 51 and the grip 52 are kept apart or held in a normal position by a small spring 58. By squeezing the grip 52 and the lever 51 together the curved clamp 56 can be opened, the purpose of the clamp 55 being to hold the heater 5| in place after it is positioned over a lock of hair. In the Figure '7, I show the clamp 55, in an open position and designate this alternate position by the character 56a.
Inside the chamber 5|, and close to its larger wall there is a wire screen 53, extending for almost the entire length of the heater. Between the wire screen and the inside or moreconcave wall is the catalytic agent 41. The catalytic agent 41 consists of pulverized or granulated platinum or palladium interspersed in a packing of metallic wool, asbestos fibres or other suitable material.
Through the grip 52, and entering the chamber 5i, is an opening designated by the character 54, through which the exothermic gas 59, or the air 29, may enter. The wire screen 53 serves as a distributor of the gas or air to permit more even combustion or cooling. This screen 53 also prevents the catalyst 41 from falling out of the chamber 56. In addition it prevents any flame which might be caused by the combustion from leaving the chamber by way of the opening 55 or by way of the burnt gas outlets or exhausters 55.
If a fuel such as methyl alcohol is used, the fumes caused by combustion may contain formaldehyde. It has been found, however, in practice that the amount of formaldehyde so formed is so negligible that no possible harm or deleterious effects can be attributed to its use. The ammonia water or borax water saturated pads T1 or Ha in which the locks of hair are wrapped for moistening during the curling or waving operation, absorbs the small amount of formaldehyde thus created, and converts it into a harmless compound before it can possibly injure anyone. Aqua-ammonia particularly will convert formaldehyde into a harmless and odorless compound. Furthermore, it has been found that at relatively high temperature and with proper carburetion, the formaldehyde so formed is decomposed into hydrogen and carbon monoxide, in imperceptible harmless quantities. The basis for the above finding is contained in a treatise by Ford R. Lowdermilk and Allan R. Day, printed in the Journal of the American Chemical Society, volume 53, pages 3335 to 3339 (1930) and entitled A Study of Vapor-Phase Oxidation of Organic Compounds, Using Rare Earth Oxides as Catalysts, and I. Methyl and Ethyl Alcohols.
Persons familiar with the art have discovered that formaldehyde is such an agent that when brought into contact with human hair, in a suitable manner, at proper degrees of both concentration and temperature and for a sufiicient length of time, will bring the hair into a superior condition and will render it fit to take a desired form, such as curls or waves. In addition, the application of formaldehyde to the hair renews its natural luster and considerably increases its strength.
It has also been found that formaldehyde created by this apparatus, before it is slowly decomposed, has the correct properties and characteristics for imparting to the hair the desirable quality of luster and strength. The time the formaldehyde is allowed toact upon the hair is naturally dependent on various factors; for instance, the thickness of the hair, its normal moisture content and the nature of previous treatments with other chemicals. However, after the hair has been treated, any excess or undesirable accumulations of formaldehyde may be easily rinsed out with water before it can do any possible injury or harm. Thereafter the may be dried in the regular way either in the open air or by applying gentle heat as the situation may require.
The curl type of heater consists of a hollow tubular chamber made up of an outer cylindrical wall 69, an inner cylindrical wall 55, and an intermediate cylindrical wall 64, the formation and construction of which form sub-chambers 53a and 63b. The middle wall 64 is perforated so as to permit the gas 39 to evenly enter the inner chamber 635, after it has entered the outer chamber 63a, through the opening 5-5. The Figure 12 shows the perforations or evenly spaced holes 65 through which the gas enters the inner chamber 535.
Adjacent to and inside the intermediate wall 55 there is a wire screen 53 which functions the same as the wire screen described in connection with the wave heaters. Between the screen A? and the inner wall 55 is the packing sprinkled with the pulverized catalyst 57. At the top of the inner chamber 63b are exhausts 55 to permit the burnt gas to escape. The curl type heater also has a grip which is round instead of flat like the one on the wave heater. his grip is firmly attached to the chamber wall 59, and is designated by the character 52a.
In the curl heater the outer chamber 53a serves two purposes; one, to cause a more even distribution of the gas 39, and the other to keep the outer chamber wall 69 cool and comfortable at all times.
When using either type of heater, the locks hair designated as 52 and 52a in the drawings, are wound around the spindles 6i and 55a. A flannel cloth pad saturated with hair setting sclution is wrapped around or with the lock of coiled hair. It has been the usual practice in the past, when heaters not of this invention are used, to place heat insulating pads next to the scalp to prevent skin burns. Similar pads may be employed with the heaters of this invention also to prevent possible injury or annoyance to the person, if the setting solution happens to seep through the pads 11 or Tia and drips down to the skin. The heat insulating or skin protecting pads referred to are designated by the characters 1i) and 15a in the Figures 8 and 14 respectively. After the pads it, lfla T! and Ila are applied, the heaters are attached as illustrated in the Figures 8 and 14 of the drawings.
To further make my invention practical I provide for a means of conveniently attaching or removing the heaters from the flexible tubes 26. I, therefore, equip the tubes 26, with nozzles 68, which nozzles fit into the grips 52 and 52a. The nozzles 63 have a circumferential groove 12, enabling a small ball H, or some other form of clip to hold the nozzles 63, 'within the grips 52 or 52a. The lower or grooved portions of the nozzles 68 are also referred to herein as clasp members.
In order to prevent a loss of gas 39, when the nozzles 68, and the grips 52 or 52a are separated, I place a small valve within the orifice of the nozzles 68, and also insert a pin 14, into the opening 54. The valve 13 is simply a small resilient cap-like closure which fits tightly into the end of the nozzle 68. The valve I3 can be easily made of soft rubber, and has a diagonal slot 16 through which the gas 39 can pass when the valve stem 15 is pressed inwardly. The top end of the stem '15 is embedded and held in the caplike valve 13 and its lower end extends centrally through the hollow valve body and projects outwardly thereof for a short distance, the assembly being such that when the nozzle 68 is in serted in a grip and held in place therein, the fixed and rigid pin 14 will depress the valve stem 15, thereby opening the slot 16. The Figure 10 illustrates a closed valve 13 as it is normally. The Figure 10A shows the same valve opened inside a grip portion of the heater, this latter arrangement being particularly desirable for occasions when the operator desires to use only a few or a limited number of heaters.
An outstanding advantage of the invention herein described and claimed over the prior art devices which use quick lime and water for their exothermic agents, is that the gases used or the liquids resulting from their combination are harmless to the hair and person. In fact, they have certain therapeutic and detersive values as well as being analeptic and restorative in nature; as distinguished from the harmful effects of the quick lime saturated water and steam heretofore used. It is a well known fact that quick lime has a deleterious effect on living organisms and particularly has a tendency to make human hair dry and brittle and also causes it to lose its life-like natural color and texture.
