1 Claim.

My invention relates to improvements in hair drying apparatus of the type used in hair dressing establishments and in the so-called beauty parlors, and the invention has reference par- 7 ticularly to the construction 01' the head covering hood and the means used to conduct and guide a continuous blast of heated fresh air from the hood into the hair and out again after. picking up the moisture therein.

The use of warm air supplied from a head covering hood is well known, but the success in drying hairquickly resides in bringing the heated dry air into contact with the wet hair and then, after picking up the moisture, to be allowed to escape almost immediately.

It is therefore an object of my invention to provide a portable apparatus comprising a stand mounted upon castors and equipped with a blower, air heating unit and a helmet or hood, 20 which is specially constructed to receive and distribute a continuous blast of warm dry air into the wet hair of the user and to allow the air after absorbing the moisture in the hair to escape to the exterior of the hood in substantially the immediate vicinity of the places where the dry air has beenemitted from the hood.

It is a further object of this invention to construct a hair drying hood of this character having spaced inner and outer walls, the chamber in- 30 termediate the walls receiving a continuous supply of warm dry air, which is emitted through a plurality of perforations in the inner wall, and which is conducted from the inside of the hood outwardly through tubes opening out of the inner and outer walls.

In practice I accomplish the objects of my invention by means of a hair drying apparatus one embodiment of which is illustratively exemplified in the accompanying drawing, in which:

Figure 1 is a perspective view of the hair drying device, and

Figure 2 is a substantially longitudinal sectional view taken through the hood.

Referring to the drawing, l denotes a pedestal having laterally disposed feet ll provided with castors l2 set in rubber bushings. An arc-shaped support I3 is mounted upon the pedestal l0 and provides a socket to receive and embrace the lower portion of an annular casing M, which en- 2 50 cases an electric fan unit l5, which terminates at its upper side in a tubular throat portion IS, The details of the fan or blower unit I 5 have not been illustrated because any of the well known devices of this kind may be used. Attached to the throat 55 I6 is a short tubular union l1 enclosing electric heating coils l8 through which air emitted by the blower II is conducted, dried and heated. The upper end of the union ll carries an upright tube is having a collar 20 at its upper end in which athumb set screw 2| is mounted. Telescopically 5 arranged in the upper end of the tube I8 is a second tube 22 which fits snugly in the first tube and which is fixed in any adjacent position in the first tube by engagement of the set screw 2 I The upper, end of the second tube 22 consists of a 10 length of flexible tubing 22 and socket 24.

Supported on the socket 24 is a hood 26 which may be or any suitable shape best adapted to fit over the head of the user. In the present construction the hood comprises a substantially hemispherically shaped outer shell 2! and similarly shaped inner shell 21, the latter being somewhat smaller than the outer shell 26 is spaced therefore to form a closed chamber therebetween. The inner wall is provided with a plurality of spaced slots or perforations 28 from which the heated dry air entering the chamber is allowed to escape into the space inside the inner shell 21 and consequently to the hair of the user whose head is disposed beneath the hood. Intermediate the 25 slots 28 are arranged a plurality of openings formed by the inner ends of radially arranged tubes 29 the outer ends of the latter being pro- Jected through the wall of the outer shell 28, so as to provide conduits through which the mois- 30 ture laden air inside the inner shell is allowed to escape to the outside of the hood. The tubes 29 project through the chamber between the inner and outer shells of the hood as illustratively exemplified in Figure 2. The first two, rows of tubes 29 at their outer ends in the outer shell are provided with upturned lips 30 to direct the escaping moist air upwardly away from the operator who attends the device. The radial tubes 29 are arranged preferably to follow a spiral course from the lower open end of the hood towards the top.

In operation the hair drying device is wheeled close to the chair oi the user by an operator, who adjusts the height of the hood 25 and sets the screw 2|. The flexible neck portion 22 is adjusted to give the hood exactly the position desired and allow it to be placed over the head of the user. The inner open edge oi the inner shell 21 carries a soft rubber head band II which flts loosely to the head of the user to form a seal.

To continue the operation, the electric fan and heating units are switched on and warm, dry air is forced into the inner chamber of the hood and 20 Having now described my outwardly through the slots 28 and into the wet hair. Because of the adjacent outlets through the tubes 28 the air quickly picks up a quantity of moisture and escapes'with it through the adjacent tube 29 to the outside of the hood. 0! course the degree or heat transmitted to the air and the velocity of the moving air may be governed by the heating unit and the speed of the fan.

It has been found that by the use of the present dryer the time ordinarily consumed in the drying process is greatly reduced, with a minimum of discomfort to the user because the warm moist air is conducted upwardly and away from the face. The better results in the drying process are brought about by providing a constant supply of warm dry air Jets over the entire head of the user and thereafter discharging the air at points closely adjacent the inlets.

invention and the manner in which the same operates, what I claim and desire to secure by Letters Patent is:

In a hair dryer a hood comprising inner and outer spaced shells forming an intermediate closed chamber to receive air under pressure, the inner shell having a plurality of spaced openings through which the air passes in jets to the interior of the hood, and a plurality of tubes projecting through the chamber between the shells and opening into the hood at their inner ends and outside the outer shell at their outer ends to pass air from the interior of the hood to the outside, said tubes being disposed in a plurality of rows substantially concentric with the lower end of the hood, the outer end of the tubes disposed adjacent the. lower open end of the hood being provided with outwardly and upwardly directed lips, whereby the air escaping from the hood is directed upwardly and away from the operator.
