4 Claims. (01. at-e9) I This invention relates to an hair drier, and more particularly to a hood for such a drier.

A primary object of this invention is the provision of an improved hood or adapter for hair driers wherein the loss of heat and heated air is reduced to a minimum.

A still further object is the provision of such a drier adapted to be used with a minimum of discomfort to the user, precluding access of heated air to the face and skin.

A still further object is the provision of such a device adapted to reduce to .a minimumthe noise occasioned by conventional hair driers in order to'avoid annoyance or discomfort to the user thereof and permit conversation in normal tones.

A more specific object is the provision of an adapter unit which may be applied to a conventional hair drier or the type now in use.

A still further object is the provision of such a device which may be readily adapted to be applied to hair driers now in the course of manufacture.

Still further objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and disclosed in the accompanying drawings, wherein there are shown preferred embodiments of this inventive concept.

In the drawings:

Figure 1 is a side elevational view disclosing one form of adapter unit incorporating features of the instant invention.

Figure 2 is a bottom elevational view of the device shown in Figure 1.

Figure 4 is a sectional view taken substantially along the lined-4 of Figure 2,-as viewed in the direction indicated by the arrows.

Figure-5 is a sectional view taken substantially along the line 5-5 of Figure 4 as viewed in the direction indicated by the arrows.

Figure 6 is a front view partially in section, and partially in elevation of a modified form of this invention.

Figure 'l is a view, in section, of a modified form of one of the parts of Figure 6.

Figure 8 is a still further modified form of one of the parts disclosed in Figure 6, viewed in section, and

Figure 9 comprises a still further modified form I of this device.

Cal

Like reference numerals refer to like parts throughout the several views of the drawings.

Having reference now to the modification shown in Figures 1 to 5, inclusive, there is gener ally indicated at Ill a chamber adapted for the heating and propulsion 01' air, containing within its interior an electric motor H (see Figure 4),, a

heating grid II, a fan It, actuated by the motor and adapted to flow air over the heating grid l2,

and provided with current from any suitable external source as through a wire or conduit II. The arrangement heretofore described is more or less conventional and no claim is made thereto in the instant application.

Suitably affixed to the lower portion of chamber ill, a wind cone or tunnel I! is adapted to direct the heated air toward the hair of a subject, schematically indicated at It, (see Figure 4) for the purpose of drying. The lower portion of wind tunnel I5 is provided with a flange ll to which is adapted to be secured the peripheral rim ll of an aperture in the upper extremity of an adapter or the like generally indicated at l8. Adapter is is comprised of a relatively cylindrical body portion encompassing an air circulating concentrating chamber 20 provided at its upper extremity with'a curved peripheral portion 2| constituting a hollow perforated torus terminating in a flange or extremity l8. Suitable apertures 22 are provided in this modification to permil; the escape of used and surplus air circulated within air chamber 20 said apertures being positioned wholly behind the discharge end of the cone whereby air must circulate through the adapter before it may escape from apertures 22.

The lower portion of the device is curved to coni an elastic band 28 of a general configuration adapted to coniorm to the outline of the head. In operation band 26 is adapted to be positioned about the head of the user above the ear. The fan i3 is then turned on and the grid l2 heated and the air circulated through air chamber 20 being guided upwardly and downwardly in circulatory fashion by grooves or dips 2| and 23, and ultimately escaping through apertures 22. A relatively tight seal is effected about the head of the user and below the hairline by the band 26.

From the foregoing it will now be seen that the adapter device of the instant invention is adapted to conserve heated air as well as protect, the skin 3 of the user during the operation of the device and preclude substantially the passage of noise from the fan and motor to the ears of the user.

Having now reference to the modification shown in Figure 6, there is disclosed at 30 an air heating chamber similar to chamber l and a cone 3| similar to cone I5. Secured to, or integral with the upper peripheral rim of pone 3| is a circular annulus 32 provided with a seriesof rows of escape apertures 33 about the periphery thereof, and having an annulus 34 about the face thereof. In this embodiment the apparatus is provided with an adapter or circulating chamber 35 provided with a groove or dip 36 similar to the corresponding groove 23 in the previously described embodiment and having a cloth or similar flexible sealing member 31 provided with an interiorly disposed recess surrounded by an. elastic band 38. In this embodiment air 'mixing or circulating chamber is not provided with escape apertures, the air being permitted to pass for engaging the head of the user immediately below the hair line, a hollow perforated torous at the opposite end of the body, the perforations of which are located wholly behind the discharge end oi. the cone whereby air introduced into the hood through the cone cannot escape without circulation therethrough.

2. In a device of the class described, the combination with a conventional hair drying unit having a warm air directing cone, of an air circulating hood adapted to be attached to said cone which comprises a hollow substantially cylindrical body having an inturned flange at its lower end, flexible sealing means carried by the flange for engaging the head of the user immediately below the hair line, a hollow annular torous at the opposite end of the body, said torous at least upwardly between the wall of cone 3| and the wall 32 to escape through the apertures 33, Figure 8 discloses a modified form of construction including an air cone 40 surrounded by a cylindrical wall 4| oil'set as by a band 42 from the periphery of the cone and correspondingly provided with escape apertures 43 and a. flange 44 to which an air circulating chamber may be attached.

If desired the air circulating chamber may take the form disclosed in Figure 7 being provided with a circular exterior wall 50 having a plurality of apertures 5i therein, which latter chamber is adapted to be utilized in conjunction with a wall about the air cone which may be either provided or not provided with apertures as desired.

Having reference now to the form shown in Figure 9 there is disclosed an air cone 55 to which is secured, in any desired manner, a flange circular in configuration and arcuate in cross-section, provided with apertures 51 and an extending peripheral flange 58 to which may be secured any desired type of air circulating or mixing chamber.

From the foregoing it will now be seen that there are herein provided a plurality of devices accomplishing all the objects of this invention and others including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiments hereinbefore described and shown in the accompanying drawings, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

1. In a device of the class described, the combination with a conventional hair drying unit having a warm air directing cone, of an air circulating hood adapted to be attached to said cone which comprises a hollow substantially cylindrical body having an inturned flange at its lower end, flexible sealing means carried by the flange partially embracing the cone and having an annular row of air escape openings disposed wholly behind the discharge end of the cone,

3. In combination with a conventional hair drying device having a warm air directing cone, an air circulating hood attached to said cone and including a hollow, substantially cylindrical body, annular troughs internally of each end of said body. an ape ture for loosely receiving a head at the lower end of said body, flexible sealing means secured to said body at the under side of a trough for engaging the head of a user below the hairline, and a plurality of apertures in said other trough for discharging air from said hood only after circulation thereof from said cone and throughsaid hood.

4. In combination with a conventional hair drying device having a warm air directing cone, an air circulating hood attached to said cone and including a hollow, substantially cylindrical body, annular troughs internally. of each end of said body, an aperture for loosely receiving a head at the lower end of said body, flexible sealing means secured to said body at the under side of a trough for engaging the head of a user below the hairline, and a plurality of apertures in said other trough for discharging air from said hood only after circulation thereof from said cone and through said hood, said other trough and apertures therein being positioned rearwardly of the discharge end of said cone.
