This inventionrelates to improvements in apparatus for the treatment of hair. More particularly, it has for an object the provision of an improved apparatus for drying hair in the beauty treatment of hair. 4

An object of my invention among others has been to dry hair which has been set in the course of a'beauty treatment more rapidly and more uniformly.

Another object among others has been to increase the permanency of waves in beauty treatments.

Still another object has been not only to eliminate the disadvantage of the long periods which it has been necessary to wait for hair to dry, but also to eliminate disadvantages such as hot blasts of air blown across the face of the person being treated.

The disadvantages of the systems and devices now in use are common knowledge. There exists not only the disadvantage of the person being treated having to sit under a drier for long periodsbut there is also the further disadvantage that this waitingis extremely objectionable on warm or hot days, particularly in view of the fact that hot blasts of air are continually blown in the area of the face. Well-known is the further disadvantage that the hair is commonly not uniformlydried, that is, the top of the head, on which there is usually less hair, may be' baked while the hair on the back of the head may not be satisfactorily dried.

One of the features of my invention is the provision of a hood for a hair drier of unique design which is adapted to conform to the hair line to cover the hair portion of the head instead of merely the crown. 7 It is well-known that there is more hair to be dried as a general rule on the back of the head than. on the crown and I have provided a hood adapted to encase not only the hair on the crown, butalso the hair on the'back of the head and the advantage of increasing the rate of evaporation will be at once manifest.

Another feature of my invention is the provision of infra-red ray lamps to increase the rate of evaporation and the advantage of this feature will be manifest to those skilled in the art over the system heretofore used where heated air is used with the air heated at a more or less remote point by electricity, gas or other'heating element. A further feature is the provision of the lamps insuch' a position that the rays may act directly on the hair.

Another feature of my invention is the method of withdrawing the air inthe hood by suction inhead and the face. Water or other liquid rises naturally by capillary action through the hair as it is evaporating and according to the principle of my invention, the naturally rising vapors are drawn up and exhausted. That is, they are exhausted naturally to leave the hair instead of being forced down against the hair and scalp contrary to their natural tendency.

Another feature of my invention has been the arrangement of the infra-red ray lamps in greater number preferably, although not necessarily, adjacent the back of the head, particularly the lower portion thereof where the hair is usually the thickest, with a lesser number of lamps preferably arranged in the area of the crown of the head. In the form shown the exhaust apertures have been similarly arranged and this arrangement hasthe advantage of applying more rays and more exhaust means where evaporation is more needed.

Another object of my invention has been the provision of such a drier in such form as will be highly eflicient and comfortable'and easy to manufacture and assemble besides being economical in cost.

These .and other advantages I have accomplished according to the principles of my invention.

Other objects and advantages will become apparent and be brought out more fully in the. following specification, reference being had to the accompanying drawing, wherein:

Fig. 1 is a side elevation partly in section; Fig. 2 is a front elevation partly in section;

Fig. 3 is a plan section taken on'the lines 3-3 of Figs. 1 and 2; and

Fig. 4 is an enlarged section on the line 4-4 of Fig. 3. g

Referring more particularly to thedrawing in which I have selected a preferred forni for illustrating the principle of my invention, there is the lower portion of the back of the head. The 3 shown a-drier having a hood III. This includes an outer shell it formed on'a spiral or eccentric curv'e having a crown covering portion l2 extend downwardly to the forehead and an extension It at the back of greater curvature for containing shell ll terminates in'a curved turned in edge ll providing an opening l5 for the insertion of the head. The shell ll has provided, paralleling the curved edge M, a bead l6.

A clamping bead l'l maybe provided upon an inner shell ll fonclampi'ng said innershell to the outer shell as will be readily understood, without .type.

I8 around the opening l and thus around the head and face of the person being treated.

The supporting wall 20 in the form shown has a plurality of large air vent openings 22' and smaller air vent openings 23 flared toward the shell H. In view of the fact-that most of the hair to be dried is on the back of the head and in view of the fact that there is a relatively small amount of hair on the top of the head to be dried, I have preferably provided the smaller vent openings in the crown of the inner shell and, preferably, I have arranged fewer openings in the crown portion and a larger number of openings in the area of the extension l3. Experience has shown that it is common for hair on the crown of the head to be dried too much and on the contrary, for the hair on the'baok of the head to fail to get dried satisfactorily. By the principle of my invention, the requisite amount and size of vent openings will be applied to evenly dry all the hair at the same time and it will be understood that the arrangement of openings and other features may bevaried to carry out this principle' The air may be removed from the shell by suction through the vent openings, or by pressure through the vent openings. Preferably suction is desirable as by this means, the air is not drawn over the face, but drawn directly from the hair through a suitable duct. Common objection to the pressure type of withdrawal of the air is that it causes a hot blast of the air to be drawn over the face and the resulting disadvantage particularly on warm .or hot days will be manifest. By the use of suction, this disadvantage is entirely eliminated.

In connection with means for withdrawing the air from the hood, there may be provided an air vent opening 24 in the shell H and adapted to be secured to the outer shell II about the opening 24 is a flanged outlet pipe 25 hinged at 26 to an adjustable air conduit 21 on a standard 28 connected to a source of suction or pressure, if pres- .sure is desired for any reason. This source may be a fan or other suitable means.

I have arranged in the form shown a plurality of flanged openings 29 in the wall 20 of the inner shell l8 forming depressed compartments, pockets or recesses extending or outpressed into the area of the chamber 2|, with the flange directed toward the outer shell H. Adapted to be supported in the flanged openings in the chamber 2| are a plurality of sockets 30 supporting lamps 3!, which are preferably of the infra-red ray The sockets may be provided with the usual current wires 32 to a common cord or conduit 33 having a suitable plug 35.

The extension 13 may be provided with a suitable cut-out 35 for conforming to the neck.

It will be understood that the entire hood may be generally in the form of a part of the surface of a sphere or ellipsoid or modification thereof.

By the device of my invention, it will be seen that all the hair will be contained withinthe hood. It.will also he understood that a larger number of lamps may be provided in the area of the greatest amount of hair so as to cause unlart.

form heating and'drying of the hair and in the form shown I have shown a larger number of lamps in the area of the extension for the back of the head where the hair is usually thickest.

' It will also be understood that lamps of greater heating value may be used in the area where the hair is thickest. In operation, my invention will have the advantage of causing greater evaporation where it is most needed with larger openings and a greater number of them located in the area where evaporation is most needed. It will be understood that the suction may be greater or as great as desired depending upon the arrangement of the openings found most expedient.

Thus, the invention will have the advantage of creating uniform evaporation as needed and the vapors may be drawn through the openings by means of suction through the air conduit, or the vapors may be removed by pressure through the duct and openings.

The advantage of the direct application of the infra-red rays on the matter to be dried, in respect of radically increasing the rate of evaporation will be readily understood by those skilled in the art.

In accordance with the method or process of my invention, the method or process of giving a permanent or finger wave is distinctly improved as will be readily understood by those skilled in the art without further explanation.

In giving a permanent and finger wave, the hair is first washed with soap and water to remove dirt and then strands are taken together in bunches. These strands are then wrapped around curlers and are moistened with a common permanent wave solution to retain moisture. This may be a solution of five percent ammonia and ninety-five percent water saturated with borax and oils and starches may be added. The moistened. strands on the curlers have a felt pad wrapped around them to retain the moisture. The hair in the wrapped curlers is steamed usually for about six to fifteen minutes and then the strands are removed and the hair may be washed to remove the permanent wave solution;

A mucilaginous solution may then be applied to the hair, which may be made of two ounces of gum arabic in a gallon of water, to retain the set of the hair and to retain the hair in place. The hair may then be set in waves and held with the usual hair pins.

The hair may then be subjected to treatment in the drier of my invention. In accordance with the principle outlined heretofore, it will be understood that all the hair will be encased within the hood. It will also be understood that on account of the direct application of the infra red rays and their distribution and the action of the rays on the matter to be dried, the rate of evaporation will be radically increased in addition to the evaporation being uniform and effected in relation to the need for evaporation.

It will also be understood that the design of my hood with its extension for the hair on the back of the head will be advantageous also in connection with the systems heretofore employed. That is, the systems that utilize remote heat produced by electrical or other means under pressure or other such systems. i

The means employed in accordance with the principle of my invention are particularly advantageous in that they cooperate with the natural rising vapors in they drying process. The vapors are drawn up naturally along the hair as for example by capillary action and by the use of my means, in combination with suction, this natural drawing up or out of the vapors is assisted and increased instead of the vapors being forced down against the hair and scalp.

A further result of the application of the means and method of my invention is that the waves are baked and their permanency is greatly increased, which will be readily understood by those versedin this art.

It will be understood that lamps of suitable electrical value may be employed. It will also be understood that while I prefer infra red ray.

lamps, the invention is not limited to such, but other lamps may be found useful especially in combination with the design of the drier of my invention.
