Application filed October 2, 1922. Serial No. 591,828.

To all whom it may concern: v

Be it known that I, SAMUEL HUDSON, a

citizen of the United States, and a. resident of Los Angeles, in the county of Los Ang eles and State of Califprnia, have invented new and useful Improvements in Haircomplishing its purpose. Obviously the Drying Apparatus, of which the following is a specification.

This invention relates to hair drying apparatus and has for its principal object to provide for increased efliciency of operation while providing for greater comfort to the subject.

While my invention is applicable to use under all conditions for drying thehair, particular consideration is given to providing an apparatus which may be used under conditions where the hair to be dried is held in wavers, curlers or the like, as in the art of producing semi-permanent waves. It is obvious that in the above instance the strands of hair are not free to be acted upon by the air currents in theusual manner, and it isv therefore important, and it is one of the primary objects of the invention, to quite positively direct and dis tribute the air currents employed.

It will be understood in the consideration of the invention that the usual hair drying apparatus consists 0f a blower cagable of, supplying warm air, and a flexible ose for directing the warm air... The usual procedure is to secure a towel .'or the like around and over the subjects hair, and to tie this towel to the flexible tube in such a manner that the towel receives all the air and holds itpocketed adj acent'the subjects head until saidair can escape through the interstices of the towel fabric. The most satisfactory type of blower used is the centrifugaltype, which displaces a large'vol ume of air but at a necessarily low pressure. Hence the difliculty with which the air. can escape under the conditions of the above'described procedure, sets up a back pressure and appreciably lowers the efiiciency of the apparatus. Also a pocket of. air forms adjacent the subjects hair and scalp, while the fresh warm air simply flows over the inert pocketed air and escapes without acpocketed air becomes fully saturated and can absorb no more moisture from the hair. I have also found the flexible hose to-be cumbersome to handle, and at times incon- 1 throughout all to the device.

venient to the subject. It is usually necessary to maintain a higher air temperature Y in the above procedure, todiscomfort.

In view of the foregoing it is another object of the invention to provide a hair drying apparatus capable of setting up a flow of heated air over the subjects head and hair in a manner to quickly absorb and carry away the moisture therefrom without subjecting the blower to a back pressure and in a manner to insure even drying efi'ect parts of the head subject the subjects Another object of the invention is to provide a device of the above character capable of readily being adjusted inelevation and in which the porting;

Another object of the invention. is to provide a hair drying apparatus in which due'consideration is given to sanitationby parts 'are rigid and self supproviding for any part of the apparatus coming in actual contact with the'subject being removable for washing and sterilization. o i

Other objects and advantages of my invention will appear hereinafter and will be better understood by virtue of their 00- ,currence in the specification.-

I have illustrated by the accompanying drawings a preferred embodiment of my invention, and it is conceived by me that numerous changes in construction and arrangement of parts and other embodiments will suggest themselves to the minds of those skilled in the art, and I do not limit myself to any specific construction or arrangement of parts, but may alter same as I desire, without enlarging the scope of my invention, and without departing from the spirit thereof, within the appended claims.

In the said drawings, a .Figure 1, is a view mainly in elevation of my improved hair drying apparatus;

Figure 2, is a; view in enlarged detail vertical section of a part of the apparatus hereinafter termed the hood.

.Figure 3, is a ,view in section seen on a 7 line 3-3 of Fig. 1 looking the direction 2 parts, 4 indicates a blower operable by an outwardly, and through this space air section 11 of said air conduit.

discharged from the blower. Blowers of this type for delivering warm or cold air are well known and need not be specifically described or illustrated herein.

[To the spout is affixed an air conduit 8 asby a bayonet lock 9, whereby it is readily detachable. In keeping with the objects of the invention said conduit is preferably rigid, but for the purpose of increasing or decreasing its effective length, it is here shown as made up of a plurality of relatively

telescoping sections

10, 11, etc.

Now it will be apparent that upon the blower being put in operation and the heating element energized volumes of warm air will flow through said conduit.

One of the salient features of my invention resides in an air directing hood 16,

which is formed of a rigid material, such as sheet metal, and impervious so that air cannot escape therefrom except in the manner hereinafter explained. Said hood isof substantially inverted bowl shape and is formed with 'an air admission aperture as at 17. Said aperture is'slightly elliptical in form and is partially closed by a shield 18, which forms an integral portion of a Said shield is formed withan aperture 19,'whereby air flowing through said conduit may enter said hood. The hood is secured pivotally to the conduit section 11 by a pin 20, which passes through both the hood and the said section. It will be apparent now that the hood may be moved to various angular positions relative to the major axis of the hood, while the shield 18 will serve to keep the joint between the hood and the conduit suitably air tight.

The blowers of the. type shown are generally mounted so as to e oscillatable about their centers for adjustment purposes, and in the embodiment shown, said blower is shown as mounted on an arm 21 directly at its center, and said blower may be held in any adjusted position by tightening a thumb screw 22 which co-acts with the arm' and blower casing in the usual manner to promote frictional engagement between the provision for swinging thehood relative to Leas es the conduit, and by the provision of a. telescoping air conduit, the hood may be adjusted to any vertical and forward position with respect to a surface'or other fixed element 23, to which arm 21. is attached.

Air entering the hood and having the usual velocity, or the usual pressure behind it, will be forced downward in, and will spread out and fill, all portions of the hood as indicated b the arrows in Fig. 2, and will be compel ed to flow to the lower edge 2st thereof before it can escape. Extending around and preferably-below, while being spaced from the outer surface of the hood, an annulus 25 is provided. Said annulus also extends upwardly a suitable distance above the lower edge of the hood. Thus a vertically rising air discharge space 26 is provided which extends annularly around the lower portion of the hood.- Thus a counter-flow of air is set up. The air rising in space 26 flowing contrary to the air descending within the hood serves to keep the hood and annulus at practically the same temperature so that the tendency of moisture to precipitate, immediately the air leaves the hood, is substantially reduced. Another purpose of the annulus is to provide for a flexible skirt 27 being supported thereby so that air cannot flow downward aroun the subjects face, and said skirt of course serves to retain the hair of the subject within areas swept by the warm air currents. Said skirt is preferably of a pliable material and capable of being removed for Washing and sterilizing, although it is conceived that a common towel may be temporarily bound around the subjects head and the annulus jointly in place of saidv skirt.

Tnteriorly of the conduit, at the end where it discharges to the hood, a bafile 28 is secured to the conduit; said baflie is "made of a soft .metal so as to be capable of being bent into dotted'line position, and may be employed to redirect the air currents should j While the operation and application of the device is practically apparent from the foregoing it may be better understood from the following: The hood is positioned suitably'over the subjects head, as indicated in Fig. 2, and the flexible skirt or a towel secured around the annulus as shown to place the subjects hair i' in substantially direct communication with the interior of the hood. Air entering the hood will flow in the direction indicated and will thus be compelled to actually 'contact with the subjects head and hair. The drying effect of heated and expanded air in constant motion and constantly renewed is well known, and it will vbe apparent noW that I have provided an efiicient hair dryin apparatus by allowing the air to enter an escape freely, and without setting up a back pressure on the blower, while being quite accurately and positively directed. Any of the well known means common to warm air distributing apparatus may be employed for controlling the temperature of the air.

While I have shown and described a specific embodiment of my invention, I do not limit myself thereto, but may alter the construction and arrangement of parts as occasion requires, and may otherwise modify the ap aratus within the limits of the appended claims.
