GOLDEN GRACE HATTON INVENTOR.
ATTORNEY United States Patent 3,141,463 AUTOMATIC PRESSURIZED HAIR CURLER CARRYING CQLD WAVENG SOLUTIQN Golden Grace Hatton, 332 SE. 2nd Ave, Miami, Fla. Filed Mar. 9, 1962, Ser. No. 178,705 Claims. (Cl. l3242) This invention relates to an automatic cold permanent wave curler for use in the cold permanent waving of hair.
Straight hair is permanently waved by creating a strain on the round hair shaft by winding it on a curling rod, and then permanently flattening'the hair shaft by a chemical rearrangement of the molecular structure of the hair shaft. To produce a cold permanent in the presently well known conventional manner, strands of the hair are wound tightly around curling rods of various desired diameters and then secured in place by a length of rubber band, or other flexible material. These coiled hair strands are then wet with a suitable cold waving solution by the operator, who applies it to the outer exposed surface of the roll or coil of hair using hand-held cotton pads. In this process, the outer layers of the coil or roll of hair is that portion of the hair strand which grows nearest the scalp. This outer layer receives therefore, a more thorough impregnation than the inner layers which are wound close to the curling rod. Therefore,
the hair closest to the root receives a tighter curl than the outer ends of the hair strand which is often left uncurled. This is exactly the reverse of the desired effect, since a more pleasing wave is produced when the outer end portions of the hair strand receive the tighter curl.
Another objection to performing this operation by present known methods is that it is almost impossible to thoroughly saturate the rolls or coils of hair without wetting the scalp with the waving solution, and even having the solution dripping into the face of the subject. This is extremely undesirable since such solutions are usually irritating to the skin and unpleasant or even dangerous in the eyes, nose or mouth. The hands of professional hair dressers, or, in the case of the home wave, the user who personally applies the curling fluid herself, are frequently irritated and burned by the acid contained in the curling fluid. This acid quickly builds up a sensitivity to the solution in the skin of the hands of the operator or user, and makes it necessary for the hair dresser or beautician or the person giving themselves a home wave to have to work in rubber gloves.
Many hair dressers have had to give up the profession entirely, even though their basic education in time and money was expensive, and go into less inviting means of a livelihood for this reason alone. They actually become allergic to more and more chemicals used in their work brought about solely by first becoming allergic to cold Wave solutions.
Another disadvantage to presently used methods is that the operator or beautician has had to wet the hair with the wave solution and wind the most resistant section of the hair first, usually the back of the head from ear to ear to the nape of the neck. The wave solution starts processing this section immediately, so that by the time that the entire head is finished and the operator is ready to apply the solution to the top of each upper and frontal individual rolled curl, some of the hair, as a consequence, is usually over-processed, making the hair dry and brittle and too curly in places.
All modern cold waves stress one point, the rolled hair must be wet thoroughly, if the hair has been wound too tightly, it is almost impossible for the wave solution to penetrate through from the outer strands of the coil of hair down to the inner ends.
The user is frequently disappointed as a consequence, to find that when the curlers have been removed, her wave is as nice as she desires close to her head, that is, the hair wound as the last layer on the outer surface of the coiled hair, but that the outer ends of the strands of hair, when unwound, are objectionably straight, for about one-half of an inch to an inch and a half from the outer end is straight due to lack of penetration of the cold wave solution. This is caused because the outer end of the strand of hair becomes the inner layer of the roll of hair on the curling rod. The wave is not uniform due to inability to work fast enough or faster than the processing time of the solution.
The aim of permanent waving is to give a natural curl to straight hair so that the hair may be brushed, shampooed and handled as though it were naturally curly.
All of the past cold Wave methods have been distinctive in that the solution is applied to the outside of the round curl of hair. Some attempts have been made to apply the solution from the inside out but all have failed because the wave solution is not evenly distributed.
The automatic curlers of this invention avoid and overcome all of these difliculties in a novel and highly successful manner. The advantages of the structure of this invention are accomplished by, first, no solution is applied to the hair when winding, secondly, the hands can not contact the waving solution at any time. Third, this operation is completely automatic. Fourth, the solution is forced outwardly under pressure.
In the use of the novel automatic permanent cold wave curler of this invention, the hair is shampooed and towel dried, then rolled dry. The operator or individual user then starts on the head anywhere, a slow operator can get the same good results as a fast operator, or an inexperienced operator using a home permanent kit, can obtain as good results as the professional by the use of the automatic pressurized method of this invention.
After all the curlers are in place, a simple quick twist at the end of each chambered curling rod, constructed in accordance with this invention, releases the cold wave solution from within the interior chambered portion of the rod so that it first saturates the ends of the strand of hair, which is of the first layer, that is wrapped around the rod. The wave solution is then moved on outwardly through the entire hair coil to the outer strands of hair which form the top layer of the rod even though it may be very long hair. Since the ends of the strands of the hair, which are the first strands which are wrapped around the curling rod, receive the solution first, a curly outer end of the hair strand is insured each and every time. The wave will be uniform over the entire head as it requires only a minute to automatically release the solution by a quick short twisting movement, giving the same processing time for all curls.
The curling rods of this invention are made of lightweight materials, such as plastic, thin metal foil, or any suitable other material, and can be manufactured so cheaply that the curling rods are disposable. They are never re-used. This is an important factor, particularly in a public beauty salon where it is not practical to sterilize the presently used cold wave rods to a point where they are completely sterile for re-use. The rubber bands or flexible straps make it almost impossible to sterilize them. Another problem, which is solved by this invention, is that a woman can choose her desired hair style, that is, short, fine hair can be wound around a rod of smaller diameter containing less wave solution. A woman desiring a softer, larger wave will use rods that are of larger diameter, and may contain a milder solution, if desired.
Each cold wave kit contains a set of necessary number of rods, end papers, and ready-mixed neutralizer for waving one complete head of hair. All are disposable.
For dyed and bleached hair or abused hair, a conditioner of any desired type, which is simple and pleasant to use, may be included.
A teenage school girl can be assured of an absolute curly permanent.
The hairdressers can work faster and more accurately without fear of sore, acid irritated and burned hands.
One of the outstanding features of this invention is that the curling solution is enclosed and self-contained within the chambered curling rod, which is formed as a hollow cylinder, and after the hair has been wound upon the curler and the rubber or elastic fastener has been snapped over it to hold it in place, it is ready for a final quick short twisting operation which releases a container of any suitable compressible gas which may be CO that is carbon dioxide, Freon or nitrogen for example, by puncturing the fragile side wall of the compressed gas container. This same quick short twisting motion simultaneously aligns the elongated slots of the outer and inner cylinders which, when assembled, make up the chamber containing the cold waving solution.
In other words, after the operator or user has wrapped the curls about her head, a final quick, short quarter turn of the end piece of the assembled unit will cause the slots to be aligned permitting the curling solution to be forced outwardly, under pressure, into the hair wrapped about the curler.
No solution is sprayed on the outside of the curl, as in present popular uses or methods.
No separate bottle or spray can of the solution is required since it is all self-contained.
The flow of the solution outwardly from the center of the curler into the hair, being under pressure caused by the CO or other suitable gas, provides more even application and thorough curling and soaking of the hair with the wave solution, particularly on the inner ends of the hair. The curling rod of the present invention works quicker, is less messy to use, and has many other advantages.
This method is a definite advance in the art of cold permanent waving of hair because the hands of the operator never come in contact with the waving solution while winding the hair on the curling rod.
The solution being sealed at the factory within the curling rod itself, prevents oxidation of the reducing agent in the cold waving solution by the oxygen of the air progressively diminishing and ultimately destroying the effectiveness of the solution in the production of a permanent curl.
Having now indicated the general nature of this invention, we proceed to a more detailed description thereof with reference to the accompanying drawings in which the same reference characters are used to designate like parts throughout the several views.

The various elements of this modified form of the curling rod manufactured in accordance with this invention, shown in FIGURES 6 through 10, are substantially identical as to most of the features which are shown in FIG- URES 1 through 5, except for the type of seal employed and the degree of twisting required to release the wave solution under pressure.
FIGURE 1 of the drawing is an exploded view of one of the curling rods made in accordance with this invention. It comprises essentially three major parts. There is shown the outer cylinder A, about which the strand of hair to be curled is wound, the inner cylinder B, and end plug C, which are to be assembled at the place of manufacture before delivery to the ultimate user, in the manner illustrated in lengthwise cross section of FIG- URE 2, and partial section of FIGURE 3.
In the first form of this invention, it will be noted that the outer cylinder A, about which the hair is to be wound, may be made of plastic, light metal, or any other suitable material. Outer cylinder A has a pair of elongated slots 15 and 16 cut therethrough at diametrically opposite sides of the cylinder A, as shown in FIGURES 1, 2, 3 and 4 of the drawings.
The inner cylinder B is of similar material and of an external diameter to provide a very snug and exact fitting within the confines of the outer cylinder A when inserted therein, as shown in FIGURE 2. This inner cylinder B also has a pair of similar longitudinally extending slots 18 and 1?, which are diametrically opposed to each other but arranged at a angle of the arc of the cylinder with respect to slots 15 and 16 of outer cylinder A, as is clearly illustrated in enlarged cross section in FIG- URE 4. Inner cylinder B is provided with screw threads 20 formed around one end of its outer periphery, as illustrated in FIGURES 1 and 2, and the inner walls of the corresponding end of outer cylinder A are similarly threaded internally at 21. That is to say, when the cylinder B is inserted into the cylinder A, B acts as the male member, A serves as the female member, and the threads 20 of B are the threads carried by the male member, which may be screwed into position through engagement with the threads 21 of the outer female member A. The cylinder B, when so inserted and assembled, contains the hair curling fluid, as illustrated in FIGURES 2, 4 and 5.
The end plug C is inserted in the opposite end of cylinder A and is threaded at 24 to engage the threads 25 which are formed on the inner surface of cylinder A at the end where the plug C is inserted, as shown. Plug C becomes the male member in this instance, and is inserted into the female member A by screw threading when assembled at the factory. It is to be understood that this assembly may be efiected by a drive fit connection without threads, if desired, or it may be welded or permanently fixed to close and seal off this end of cylinder A by any well known means which will fix the cylinder C in fixed position in the end of the outer cylinder A of the curling rod once it is in place.
It is not to be moved thereafter. This end plug C contains CO gas, or other suitable gas, for creating pressure when released, which is sealed in at the factory and has an end wall 26 which is of light metal and which may be readily pierced or ruptured when desired.
The inner end of the internal cylinder which contains the curling fluid has a sharp center point 27 fixed thereon, adapted to pierce this thin membrane 26 of the CO gas contained in plug C.
A suitable projecting knob 39 extends outwardly from the end of the plug C, and a similar projecting knob 31 extends outwardly from the liquid containing plug B, as clearly shown in FIGURES 2 and 3.
A strap or elastic cord 32 is slipped over the projecting knob 30 by means of an aperture 33, which is adjacent the end of the strap, as clearly shown in the drawings. This strap 32 also has an aperture 34 formed adjacent its opposite end which can be snapped in position over the projecting lug 31 of the inner cylinder B, when desired, as clearly shown in FIGURE 2. This strap may be of any suitable elastic material and is well known in the art.
The operator wraps the hair around the completely assembled three-piece curling rod, as shown in FIGURE 3, which hollow rod contains the liquid curling fluid sealed therein, as shown. When the hair has been wrapped about the cylinder A the desired number of turns, the elastic strap 32 is snapped in position over the projecting lug 31 to hold the hair in fixed curled position around the curling rod.
After the operator has completely wrapped all of the curls desired in this fashion, ten, twenty or more, it will be noted that up to this point, the hands of the operator or user have not contacted the liquid curling fluid acid in any way, it all being sealed within the assembled threepiece curling rod, A, B and C.
Now all that remains to be done is to give the outer knurled end 35 of the inner cylinder B a quick twist which amounts to a quarter turn, that is 90, whereupon two things happen. First, the threads 24 and 25 permit the male member B to be further screwed and advanced into the female member A. The pair of slots 18 and 19 of the inner member B are thereby brought into alignment with the slots 15 and 16 of the outer cylinder A, which for-ms the curler about which the hair curl has been coiled as shown. Second, this same quarter turn movement advances the inner cylinder B sufficiently for point 27 to pierce the membrane 26 of the CO gas containing plug C. This gas then escapes from the plug C into the central part of the curling rod and on through the slots 18 and 19 of the inner liquid containing cylinder B and the aligned slots 15 and 16 of outer cylinder A, through the coiled hair under positive uniform pressure of the CO gas.
In order to insure an exact alignment of the slots 15 and 16 of outer cylinder A and the slots 18 and 19 of inner cylinder B and to effect exactly a quarter rota- 5 tion movement, a pair of stops 36 and 37 have been formed or fixed on cylinder A adjacent the slots 15 and 16 of said outer cylinder, which are arranged in position to abut projecting stop lugs 38 and 39 which are carried by the outer projecting knob 35 of the inner cylinder B, as clearly illustrated in FIGURES 4 and 5.
FIGURE 4 shows relative position of the parts of the automatic cold permanent wave curler of this invention in the position they assume before use, with the slots of the cylinders A and B as they would be arranged when they leave the factory with the liquid hair curling fluid contained and sealed therein.
FIGURE 5 illustrates the automatic cold permanent wave curler of my invention after it has been given the quarter turn, above described, which aligns the slots 15 and 16 of the outer cylinder A with the slots 18 and 19 of the inner cylinder B, after point 27 has pierced the sealing Wall 26 of end plug C permitting the CO gas to force the liquid out under pressure through the coiled hair so that it becomes instantly and thoroughly saturated from the inside out. This operation of aligning the respecitve slots, 15, 16, 18 and 19 and releasing the CO gas to create the desired pressure, is quick, automatic, and prevents any curling fluid acid to contact the operator or users hands.
Another form of this invention, designed to meet the same conditions and provide inside-out flow of liquid under strong instantly released pressure in a manner whereby the operator or user does not get the fluid on her hands during the operation, is illustrated in FIGURES 6, 7, 8, 9 and 10 of the drawings.
This alternative form works in nearly the same manner as the one previously described, with the single exception that the diametrically opposed slots 15, 16, 18 and 19 of inner cylinder B and outer cylinder A, respectively, through which the curling fluid flows under pressure, are in alignment as assembled at the factory, but sealed by a thin metal foil or other suitable material membrane 49 and 41 when the automatic cold permanent wave curler is assembled and the fluid is permanently and positively sealed within the hollow curled cylinders A and B, against any evaporation or possible leakage or damage, and these seals, 40, 41, are not broken until the operator gives the final quick twist which causes point 27 to pierce the wall 26 of the CO gas container C and permits this gas to force the curling fluid outwardly under strong pressure through said slots to thoroughly saturate and impregnate the hair which is wound about the curler.
In detail, this alternative method is arranged as follows:
The same three major parts A, B and C are utilized. That is outer cylinder A, with inner cylinder B inserted therein at the factory, as is end plug C which contains the CO gas.
The point 27 is provided for piercing the thin wall 26 of container C to release the gas, and end knobs 30 and 31 are provided for securing flexible strap 32. The only difference in the modified form of automatic cold permanent wave curler, illustrated in FIGURES 6, 7, 8, 9 and 10, is that elongated slots 18 and 19 of the inner cylinder B of this modified form are aligned when assembled with elongated slots 15 and 16 of outer cylinder A.
Seals 4t) and 41, made of aluminum foil or any other easily ruptured metal or plastic material, are provided, as clearly shown in FIGURES 7, 8, 9 and 10. These seals are fixed to the outer cylinder A and inner cylinder B of the device in any suitable leak proof manner, by adhesives or otherwise, extending across the aligned slots 15-18 and diametrically opposed aligned slots 16- 16, as shown.
This arrangement completely seals the waving fluid within the central chamber of the curling rod when assembled at the factory. It positively prevents leakage and evaporation when the curlers are stored or in transit.
When the operator or user has wound all of the hair curls about all of the curling rods desired, she releases the curling solution by a quick one-half turn of outer end knurled knob 35 of inner cylinder B relative to outer cylinder A. This rotation of inner cylinder B within outer cylinder A advances the inner cylinder B by means of screw threads 26 and 21, screwing it in the predetermined amount necessary for point 27 to puncture or pierce the thin wall 26 of the CO gas container, end plug C. This releases the gas.
This one-half turn, or 180, simultaneously tears or ruptures the seals 40 and 41, thus permitting the curling fluid or wave solution to be forced outwardly through the aligned slots under strong even pressure which insures even and complete distribution of the liquid wave solution through the coils of hair, from the inside of the chambered rod out.
Stops or suitable abutments 4-5 and 46, fixed to the outer and inner cylinders A and B respectively, serve to realign the discharge slots accurately after a 180 or onehalf turn, as shown in FIGURES 7 and 8.
Changes in structural details are contemplated which come within the scope of the appended claims.
It is also understood that this device may be used with any form of curling or wave solution suitable for producing cold permanent waves or combined curling lotion and neutralizer liquids, for example, if desired.
