21 Claims.

This invention relates to certain improvements in the art of cold permanent waving of hair.

In my previous copending application Serial Number 721,965 filed April 23, 1934, granted as Patent 2,195,803 on April 2, 1940, I have disclosed the art of permanent waving of hair upon the human head by the utilization of cold hair Waving solutions at temperatures which, as compared to the prior art of hot permanent Waving, are such that the temperature of any heat applied to the hair, if applied directly to the human body, are comfortable temperatures to the human body. The invention disclosed herein makes use of andr employs certain of the features of the invention disclosed in my Patent N o'. 2,195,803, particularly the winding of strands of hair upon suitable members, securing the so wound strands against unwinding, and covering the wound and secured strands While a permanent wave curling solution is elective in the Waving of the hair, all to eliminate the clamping pads and protectors between the Wound strand and the scalp so necessary in high temperature permanent waving.

The pro-cess of this invention includes the formingc-f the hair on the head into a suitable shape, and the application of 'a cold Waving'solution to the formed hair. The temperature employed for the waving solution is a comfortable one if the solution is applied directly to the human body and below the temperature of producing steam, as is disclosed in my patent. Conveniently and usually the hair is formed into a coil form, a strand of hair being wound from` its end into coil forni to adjacent the scalp. In accordance with this invention I employ as the winding means a perforated curler. Thereafter Cil the cold Waving solution is forced through the perforated curler and the hair wound thereon, the hair becoming permanently waved while it is cold, Wound, and thoroughly wet with the waving solution. -The perforated curler enables the Waving solution to wet the hair quickly and thoroughly.

In the employment of the apparatus and practice of the method of the present application, any suitable permanent Wave solution may be employed. In my copending application Serial Number 721,965 which is now Patent Number 2,195,803, dated April 2, 1940, I named several examples ofsolutions suitable for thel plllpOse, such as alkaline water solutionof alkali metal sulphites or ammonium sulphites, which have pH on the alkaline side.

Among other permanent waving solutions which may be employed, there also may be specically mentioned sodium and potassium sulphides, but these are generally considered as Within the broad alkali metal group previously referred to as having an alkaline pH. E

Some of the cold waving solutions include sulfur in combined fonm; as is typical of most sulfur compounds, these have an odor usually considered to 'be at least slightly objectionable. 'I'hese hair waving solutions are also quite rapid in their action. To facilitate the use of these solutions it is desirable that the escape of odor into the atmosphere be Iprohibited. At the same time, to secure the best action on the hair, it is desirable that the solution be kept from access to the air so that it does not oxidize. Further, it is desirable that a minimum amount of solution be employed, and that the strength of the solution be known so that the degree of permanent waving can be controlled. l

These and additional advantages and objects will appear hereinafter wherein the practice of the process 0f the invention is set forth. It is understood that various chang-es in the method of winding hair, the form, proportion, size, and nature of the apparatus may be made Without departing from the spirit or sacrificing any of the advantages of the invention; for example, the hair may be wound Croquignole, spiral, or as pin curls, on diiferent shapes and sizes of ,curling rods, and solutions may be applied to the hair before winding or forced through the hair rolls by various systems and circuits. The operation of the system of my invention may be varied in many Ways, depending upon whether it is to be employed in a beauty shop or in a home, and whether the time required to impart a permanent wave to the hair is short or long.

' Figure 1 is a side view of a curling rod partly in section with its hinged tongue partly open.

Figure 2 shows another side view of the same curling rod with the tongue closed and a rubber locking strap buttoned on to both ends of the curling rod with wound hair in place.

Figure 3 is a plan view of a locking strap.

Figure 4 is a side view, partly in section, through a valve unit.

Figure 5 shows a bottle cap in section.

Figure 6 shows an assembly of all apparatus used in making a permanent wave by using the cold waving solution. Figure 7 shows a detailedview of part of the manifold.

Brieiiy and concisely, the present invention is concerned with the provision of a method and means for handling of the cold Waving solution in a closed system so that the Waving solution does not come into contact with the atmosphere, while a minimum amount of solution is employed and the time of contact between the waving solution and the hair can be accurately controlled on each strand of hair upon the head subjected to the process.

When a quick cold permanent wave is to be imparted to the hair, the apparatus shown in the drawing can be employed, although other suitable equlpment can be used. In practice, the head is first shampooed and rinsed. It is then blocked in a manner well known in the art, drying of the hair, a step usual in the known art, being unnecessary. Each strand or lock is wound wet and without stretching on a curling rod ll. Rods having the same external configuration are commonly employed in the art. However, the curling rod employed in accordance with this invention is hollow as at I2 so that fluid can be introduced and passed outwardly through hair wound thereon through passages I4. An extension I6 is provided at one end of each curling rod for attachment of a hose or other suitable flexible conduit whereby a, waving solution can be introduced into the rod. Each rod. of course, carries the usual tongue l1 hinged as at I8 upon the rod so that the end of the strand of hair can be suitably retained during initial winding. At the other end of the rod is positioned a buttonlike extension I9.

When the hair is wound up and the rod is finally adjacent to the scalp, a grip 2| conveniently made of a strip of 'rubber apertured at 22 and 23 is positioned with aperture 22 hooked over extension |6- and aperture 23 over button 9 so that the rod and the wound strands are locked in position on the head. It is not necessary to stretch the hair on the rod, and it is further to be noted that the clamps or pads between the rod and the scalp are omitted so that the winding of the hair on the rod can be carried very close to the scalp. The curling rod employed is only typical-the hair can be wound or otherwise retained in any shape desired by any suitable means.

The hair shaping operation is repeated until all the hair is fixed in a desired form. A connection is then made from each rod to a source of supply for the waving fluid. As appears in the drawing, the person whose hair is being waved is usually placed in a reclining position in a suitable chair 26 having a head rest 21 so that the person is comfortable. A manifold 29 is placed adjacent to the head and tubes 3| are extended between each manifold outlet 32 and tube |B on each curling rod. In the diagrammatic showing of the drawing I have shown only three rods wound on the head. This is purely for convenience and clarity in illustration, for the entire head is usually made up.

The manifold is connected to a valve structure generally indicated at 36 and shown more particularly in Figure 3. The valve structure 36 includes a ball 31 cooperating with a seat 38 in valve body 39 to permit uid to pass into the manifold when forced into the valve body 39 under pressure. The valve also includes a ball 4| cooperating with a seat 42 in the valve body. Ball 4| is lifted off the seat 42 when a suction is placed upon the interior of the valve body and its inlet 62. In this case the fluid is drawn up into the valve body, as will presently appear, through tube 6| into inlet 62. A uid supply tube 43 is connected to the inlet 44 of the valve body, the supply tube 43 extending to a. source of uid supply carried in bottle 45. Bottle 45 is conveniently mounted adjacent a sewer connection provided by basin 46 and drain 41 therein. The bottle carries a screw cap cover 48. The cap has an outlet 49 to which the tube 43 is attached, the outlet being in communication with the bottom of the bottle through vertically depending tube 5|. The bottle is filled with the cold waving solution. It is placed under pressure by operating aspirator bulb 52 connected to inlet 53 by tube 54. The operator presses bulb 52, whereupon uid at a temperature comfortable to the body is forced through tube 43 through the maniu fold, into each of the curling rods and out into and through the roll of hair thereon. The forcing of fluid through each roll is effective to wet the hair thoroughly and completely. The fluid runs down the head. To facilitate its collection, a rubber hat generally indicated at 58 is normally placed around the head with the edge of the hat suitably sealed against the skin entirely around the head. The rubber hat is so formed that it provides a sump indicated at 59 and to this sump extends a suction tube 6| connected to the inlet 62 of the valve structure 36. This rubber covering is substantially impervious to the solution due to the fact that it is made of rubber and therefore provides a sump to collect the excess solutions; it also serves (l) as an intermediate conduit back to the source of solution supply, (2) to keep the solution from contact with the atmosphere to prevent odors and evaporation of the solutions from the wound strands and (3) retains body heat to expedite and facilitate the hair waving operation. When the operator releases bulb 52, suction is placed on the valve body, because the normal suction end of bulb 52 is sealed by faucet 66 and hose 61. This raises ball 4| oi its seat and fluid is sucked up through tube 6| past the ball 4| and is returned to the bottle.

The bulb is pressed and released a number of times throughout the curling period so that solution is forced positively through the roll of hair.

r When the predetermined curling period has expired a suitable rinse is passed through the roll of hair. Usually water from a water supply under the control of faucet 66 is passed through tube 61 into the aspirator bulb 52, into the bottle 45, and out through the manifold system, through the curling rods and the rolls of hair. The water, of course, replaced the solution in the bottle. When the water level in the sump 59 in the rubber hat 58 rises sufciently it drains off through drain 69 into the sewer connection 41. After a few minutes the hair is thoroughly rinsed. Water is then turned oi, the hose is disconnected, the rubber hat removed, the manifold tubes removed, the curling rods released, and the hair unwound. The hair will then be found to be curly. Thereafter it may be arranged to suit the owner.

It is understood that various changes in the method of arranging the hydraulic circuits may be resorted to and the application of the solutions to the hair can be varied without departing from the spirit or sacrificing any of the advantages of the invention; for example, the solution can, after leaving the hair, pass by gravity i into a receptacle from which the solution is pumped into the hair again, and the solution can be sprayed over the congured or rolled hair instead of being forced through the rolls of hair. 'I'he container for the solution can be kept at any desired temperature' below a temperature which is uncomfortable to the human body.

As the rinse' I can employ water successfully, a weak sodium bicarbonate solution, a weak acid solution as a vinegar, or any other chemical that will neutralize or remove the hair Waving solution.

This case is a continuation-in part of my application Serial Number 721,965 filed April 23, 1934, now Patent No. 2,195,803 issued April 2, 1940.
