' 1 claim. (c1. 34926) This invention relates to a hair drier control and has for an objectr the provision of an improved means for controlling the now of hot air from a hair drier to diierent portions of the head.

Asis a well known fact, at least ninety per cent of beauty parlor patrons in dressing their hair have their hair parted either on the left side or on the right side of the head. This manner of dressing the hair leaves one side of the hair on the head very thin and the other side and back of the head very heavy. The thin side of hair onthe head under the usual hair drier drys in about ten to fteen minutes, while the heavy side takes about thirty to forty minutes to dry.v With this invention, however, the drying of the Vhair on the thin side is slowed up, while the drying of the hair on the heavy side and the back is speeded up.

With this invention it is possible orvhair dressers or patrons to regulate the hot air from the hair drier while drying the patrons hair, so that the air flowing from the hair drier can be directed onto any desired part of the patrons'head in such a way that it will not damage the hair that is already dried, but will flow the air on the damp part ci the patrons head only. The hair will then' dry evenly and quicker as a result of this invention, for with this invention the air reaches the hair through a series of holes, some of the holes being closed off at will whereby to control and cause the air to come through the holes that are not closed oli, but that are partly closed ofi to dry the hair in the selected portions.

This invention protects the patrons from excessive heat which usually causes dizziness and much discomfort. In many cases with the present well known form of hair drier patrons slide away from underneath the hair drier due to this excessive heat in the thin spot, thereby lengthening the time of drying and adding to the expense of operation of the drier. This invention protects those portions of the hair that are dry from becoming too dry, which leads to dull lifeless hair and is harmful to the roots of the hair.

A further object of this invention is to provide a means for controlling the now of the heated air to the hair on the head of the patron at a desired rate, it being possible to allow either a full flow of the heated air or stop it oir" altogether as well as to gradually diminish the amount of heated air that is allowed to reach the head of the patron.

With the foregoing and other objects in View, as will hereinarter become apparent, this invention comprises the constructions, combinations and arrangements of parts, hereinafter set forth,

disclosed and shown on the accompanying drawing. In this drawing,Y

Figure 4 is an enlarged sectional View taken on the line 6 4 of Figure 2, and I Figure 5 is a sectional view taken on the line 5 5 of Figure e, the broken lines showing the regulator in closed position.

There is shown Vat l a hair drier of conventional construction in which the control means constituting this invention have been installed as shown in dotted outline i I in Figure 1; The hair drier I!) consists of an air tubeV I I vcontaining a motor l2, a source of electric current such as anelectric cable I3 for the motor I2, as well as for Ythe kair heating unit not shown contained within the air tube II and a support or stand I4. The airtube I I terminates in a head hood I having an inner perforated hood l@ spaced therefrom by means of spacers il and secured thereto by a connecting flange |23 thereby forming a heat circulatving chamber between the outer hood I5 and the inner perforated hood I6.

The inner hood I6v has a plurality of perforations B9 allowing the heated air from the air tube l! to pass through perforations I9 onto the hair on the head of the patron 29'. Ordinarily the heated air passes through the perorations I9 onto the patron 2U without any means for controlling the same so that the same amount of air passes through each of the perforations I9 continuously. In order to control the amount of air passing through the various holes or perforations I9 in the inner hood I6, a plurality of control plates 26 are provided within the heat circulating chamber over various portions of the inner hood E6. As shown, preferably three control plates are provided, one for each side of the front of the head and' one for the rear of the 45 head, although, as will be obvious, a lesser or greater number or" control plates may be provided. By locating the control plate 20 within the heat circulating chamber, the possibility of catching any loose strands of hair between the control plate and the inner hood as the control plates are moved is eliminated. A further advantage is that the circulation of the heated air beneath the hood over the hair is not interfered with by the presence of any control plate touching the hair. Each of these plates is operated in an identical manner to control the amount of air that may pass through that part of the inner hood I6 to that part of the head of the patron 20 that is immediately below the particular control plate in question. The control plate 20 is provided with a plurality of spaced perforations 2l, the spaced perforations 2l being of the same size as the spaced perforations I9 on the inner hood I6 and being similarly spaced. Each plate 20 is provided with a means for closing the holes 2| to be moved into registration with the holes I9 of the inner hood I6, or to be moved partially or completely out of registration therewith. This means in-v cludes a raised boss 22 on the plate 20 which is recessed to receive the end of a control lever 23 which is secured therein by means of a set'screw 24. This control lever 23 is square in cross section, as will be obvious from Figure 5, and projects through a rectangular aperture 25 in the outer hood I5.

A handle knob 26 is secured to thel outer end of the lever 23 by means of a set screwy 21. As will be apparent, moving the handle knob 26 will cause the lever 23 to move along the rectangular aperture 25 thereby correspondingly moving the holes 2| in the plate 2B into or out of registration with the holes I9 in the inner hood I6. In order to prevent the escape of heated air through the rectangular aperture 25 a guard plate 28 is provided having a square opening 29 through which the lever 23 projects, while a spring 30 about the lever 23 exerts the pressure between the boss 22 of plate 2U and the guard plate 28, thereby holding the guard plate firmly against the inside of the outer hood I 5 and keeping the rectangular aperture 25 closed at all times. This spring 3U also serves the purpose of holding the plate 20 stationary in any desired position within its limit of movement, thus holding the plate 20 with the holes fully or partially closed or completely closed according to Wherever the knob 26 may have been set at rest.

As a result of the aperture 25 being rectangular and the lever 23 being square, the plate 20 cannot twist about any axis, but will always travel back and forth over the same path, thereby positively controlling the closing off of the aperture I9 according to the desired amount. As will be obvious, each plate 20 is controlled by its own individual knob 26 and these knobs 26 may be operated either by the patron 20 herself, or by the hair dresser.

As will be obvious this invention may be manufactured initially as a, part of the hair drier IU or may be easily added thereto by any skilled mechanic. Thus, hair driers now in use in beauty parlors may take advantage of this invention by purchasing the completed invention and having them install an adjustment in their machine already in use.

The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this is not to be considered limited to the exact form'disclosed, and that changes may be made therein within the scope of what is claimed without departing from the spirit of the invention.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

A control means for hair driers having an outer hood and an inner perforated hood forming a heat circulating chamber therebetween comprising perforated means covering fractional parts of said inner hood, said perforated means being located within said chamber, means for sliding said perforated means over said inner hood so as to bring its perforations into or out of registration with the perforations of said inner hood,

said means comprising a, control lever secured to said perforated means, means for operating said control lever, said control means comprising a rectangular aperture in said outer hood, said control lever being square in cross section whereby said control lever may be moved along said rectangular aperture to correspondingly move said aperture means, and means preventing escape of heated air through said rectangular aperture, said air escape preventing means comprising a guard plate encompassing said control lever, and spring means encompassing said control lever, said spring means extending frorn said perforated means towards said outer hood to secure said guard plate against the inside of said outer hood and simultaneously press said perforated means against said inner apertured hood to thus hold said apertured means in any set position.
