9 Claims.

'I'his invention relates to an improvement in hair drying apparatus and is directed more particularly to that type of hair drying apparatus comprising a device adapted to be applied to the head of the person whose hair is to be dried and in which the hair is dried by the circulation of' a heated stream of air through the hair.

One of the objects of my invention is the provision of a hair drying apparatus of the general type above referred to, so constructed and arranged that the air employed is circulated in a closed circuit, that is to say, the air after passing through the hair to be dried has its moisture extracted and is then recirculated. This construction, as will be obvious, possesses advantages over those types of hair driers employing a blower and means for extracting the moisture laden air in that in such devices it is necessary to employ two motors, one for the blower and one for the apparatus which withdraws the air after use, whereas in my construction but one motor and blower are necessary.

A still further object of my invention is the provision of a hair drier of the general type above referred to in which the upper portion of the device which is applied to the head is hinged or pivoted with respect to the lower portion, thereby facilitating the insertion of the head of a person in the apparatus, as distinguished from those types of apparatus commonly used in which the entire apparatus is lowered over the head and raised therefrom.

By pivoting the upper portion it will be apparent that the same may be moved outof operative position, the head inserted in the lower portion of the device and the upper portion moved back into operative position again, thereby insuring that the hair will not be disarranged, and permitting the hair to be inspected from time to time as the drying process proceeds.

A still further object of my invention is the provision of a hair drier of the general type above referred to in which the lower portion or edge of the apparatus at which the air discharges is so shaped that the air after traveling through the apparatus to the front of the head will be deflected rearwardly toward the hair to be dried, thereby effecting a thorough spreading of the air and circulation of the air through and adjacent the hair.

A still further object of my invention is the provision of a hair drying apparatus in which that portion of the apparatus which is applied to the head is made in sections, each section being independently controlled as to the passage 1929, Serial No. 402,004

of air therethrough, thereby providing a convenient means of enabling the air to be properly distributed over the head, so that the moister or thicker portions of the hair may receive the greatest volume of air.

In the drawings accompanying this application:

Fig. 1 is a sectional elevational view of one embodiment -of my invention;

Fig. 2 is a section on the line 2-2 of Fig. 1;

lFig. 3 is a section on the line 3-3 of Fig. 4 showing a modified form of my invention;

Fig. 4 is a plan view of the apparatus of Fig. 3; and

Fig. 5 is a front elevation thereof.

Referring to the drawings in detail and first of all to the embodiment of my invention shown in Figs. 1 and 2, 1 designates a stand conveniently provided with rollers 2 and adjustable vertically by manipulation of hand wheel 3 on which my entire apparatus is supported.

The apparatus comprises a casing or hood designated 4, constructed of any suitable material and provided at its forward end with an inner shell or helmet 5, the outer wall 6 of the casing or hood being spaced from the Wall of the shell 5 to provide an annular air circulating space as will be hereinafter described. The wall or shell 5 is adapted to receive a portion of the head of a person, as will be seen from the drawings, and the shell terminates short of the open end of the casing or hood 4 so as to provide a space between the edge 'l of the shell 5 and the edge 8 of the wall 6 of the casing or hood 4, as shown at 9, to provide for the discharge of air from between the wall 6 of the casing or hood 4 and the shell 5 into the hair which is to be dried. The wall or shell 5 is illustrated as imperforate, but it is to be understood that this wall or shell if desired, may be provided with perforations, as for example at those portions adjacent the thickest part of the hair, adjacent the back of the head for instance. The space or opening 9, as will be understood, extends completely about the 'edge of the structure. The air which is passed between the members 5 and 6 is supplied thereto from the rear as will be pointed out hereinafter, and inasmuch as this air is conducted to the front of the device I provide a flange 10 on the edge of the wall 6 of the hood or casing 4 extending across the space between the members 5 and 6 to cause a rearward deflection and a spreading of' the air as it is about to be discharged from between the two walls. In other words, the forwardly moving air coming from the rear oi the casing or hood 4, striking this inwardly curved portion 10 of the wall 6 is deflected or directed inwardly toward the shell 5 and the hair.

The blower or fan which supplies air to the space between the members 5 and 6 is shown in the rear end of the hood at 11, and it will be seen that this blower discharges air through the passageway 12 within the hood to the space betweenthe members 5 and 6, and withdraws this air back through the shell 5 after the air is directed toward the shell by the ange 10, through the passageway 13 within the hood leading from the underside of the inner wall or shell 5 from the space between the inner wall 5 and the hair, so that with the one blower not only is the air passed forwardly between the members 5 and 6 and discharged adjacent the hair, but it is caused to be drawn from beneath the wall or shell 5 and back into the blower again, so that the air can be circulated in a closed circuit and the use of two motors, one

. for the blower and one for the exhauster eliminated, the one piece of apparatus in my construction functioning for both purposes.

As above mentioned the air which is supplied between the members 5 and 6 is heated and for this purpose I provide an electric heater 14 within the casing or hood 4 over which the air must pass before reaching the hair. Inasmuch as the air after passing the hair is to be again recirculated, I may provide at 15, for example, in the conduit 13 or at some point in the air stream intermediate the blower and the forward end of the device 4 a suitable chemical or other means indicated at 16 for drying the exhausted air before the air is again passed through the hair. In this way I am always assured of a stream of dry heated air for performing the drying function, it being understood, however, that it may be found satisfactory in some instances to rely upon the heater for the drying of the air, in which case of course the means at 16 will be omitted. The blower 11 may be driven by a small electric motor shown at M, it being understood that the entire apparatus including this motor is mounted on the stand l.

As I have mentioned above, the present invention provides a structure adapted to be applied to the head of the person whose hair is to be dried, the upper portion of the structure being pivoted so that the same may be raised. In this connection it will be seen that the device 4 comprises an upper section 17 and a lower section 18, the upper section 17 being pivoted at 19 so that it may be raised with respect to the lower section 18. The division between these two sections shown at 20 is so positioned that when the upper section 17 is raised about its pivot 19 the head may b e readily inserted or placed in the lower section 18 after which the upper section will be closed down. This is a very practicable construction, inasmuch as it eliminates any likelihood of the hair to be dried becoming disarranged in the application of the drying apparatus and it also permits of the drying operation to be observed from time to time which is of further advantage.

In the embodiment of my invention illustrated in Figs. 3 to 5, inclusive, I have modiiied somewhat the construction above described although I have retained the feature of circulation of the air in a closed circuit. In this form or embodiment of my invention the structure 4 is composed of four sections designated 21, 22, 23 and 24. The

sections

21 and 23 meet along the top of the head and extend a short distance down over the sides thereof, the

sections

22 and 24 covering the sides of the hair and a portion of the rear so that with the four sections in place the hair is completely covered just as in the form of my invention shown in Fig. 1. Each of the

members

21, 22, 23 and 24 is in the nature of an outer and an inner wall corresponding to the walls 5 and 6 of Fig. 1, the inner wall lying adjacent the hair to be dried and the two walls being spaced from each other to provide an air passage. 'I'he forward end of each of these sections is curved inwardly toward the hair so as to insure the deflecting action described in connection with the portion 10 of the outer wall 6 of Fig. 1. In other words, the forward end of each of the

sections

21, 22, etc. is curved inwardly toward the hair to deflect the air stream rearwardly through the hair.

The several sections are supplied with air by the blower 11, each section being provided with a damper shown at 25 so that the supplying of air to any section may be regulated independently of the supplying of air to any of the other sections. This is a practicable advance in this art inasmuch as it enables the air to be applied to that part of the hair where it is most needed.

In this form of my invention I have provided that the two

sections

21 and 23 may be raised in a manner similar to the upper section 17 oi Fig. 1 to permit of the insertion of the head into the apparatus and also inspection of the hair from time to time during the drying operation.
