E. o. FREDERICS HAIR DRYING HOOD Filed Aug. 15, 1929 ,x. A TTORN E YS.

Patented May 5, 1931 UNITED STATES PATENT OFFICE ERNEST o. rannnmcs, on NEW YORK, N. Y., ASSIG-NOR TO B. FREDERICS, INO.,'0F NEW YORK, N. Y.,.A CORPORATION or ew YORK HAIR-DRYING HOOD This invention consists of a novel hairdrying hood, for treatment of the ha r and scalp of the human head in connection with a device such as those disclosed in pending applications Serial No. 153,300 (filed December 8, 1926) and Serial No. 332,215 (filed January 12, 1929).

One feature of the invention is that the stream of heated air delivered from such dryer device shall be focused (as it were) upon proper portions of the hair and scalp 'of the customer being treated. Another feature of the invention is that the customers face and eyes shall be shielded from the heated draft. Another feature is that the novel hood shall be adjusted to the height of the particular customer, whether the latter be seated or standing. Other features of the invention will be manifest from the ensuing description. The invention will be best understood in connection with the ensuing detailed description and the accompanying drawings, which illustrate a preferred embodiment thereof. In the drawings:

Fig. 1 is a side view, or elevation, of the novel hood; Fig. 2 is a view of the same, as

, looked at from underneath;

Fig. 3'is a sectional View of a detail; and

Fig. 4 is a similar view ofa modification.

Preferably, the hood is made up of three sections formed of metal. The main or central section 10. is an inverted prolate trough, preferably of sheet-metal, and preferably of cylindrical form except it is open between its two lower edges 11, where it is to receive the customers head. To the front end of this main section is fitted and secured, as by rivets, a fronthood-section 12, preferably formed of spun metal, and preferably substantially hemispherical, except the lower portion thereof is cut away along a curved line, to receive a brim 13, preferably of sanitary and relatively-cool material (that is to say, a sanitary material which is a non-conductor of heat), secured to section 12, as by screws. For this purpose there is preferably employed a molded material, such, for example, as a phenolic condensation product, which has relatively good heat-insulating properties. To the rear of saidmain section 10 is fitted and secured, as by rivets, a rear hood-section 14, also preferably of spun metal, and, preferably substantially hemispherical except that its rear curves into a reduced neck 15. To the rear of this neck is fitted and secured, as by rivets, the front end of a hollow hemispherical front-member 16 of what will be referred to herein as a ball-joint; the rear end of a cooperative rear-member 17 of the ball-joint being fitted, and secured, as by rivets, to a supporting-tube 18, preferably of sheet-metal and cylindrical, by which the entire structure is supported from the device that produces the heated air. Either of the two joint-members (16 and 17 might overlap the other; but, preferably, the

(against the action of the spring) by means of a knob 21 secured to its upper end. The

' other joint-member, as 16, is provided with a series of holes, as at 22, to receive the plunger-rod when'the hood (as a whole) is in its desired position of adjustment, for accommodating the structure to the height of the particular customer being treated. lVithin the interior of the hood, and at the rear of the rear hood-section 14, is mounted a deflector 23. From the rear of the supporting-tube 18 extends a snap-spring arrangement 24, by which the entire structure is demountably connected to the device (not shown) that produces the stream of heated air.

Thestructure disclosed in connection with Figs. 1-3 comprises a universal joint for permitting universal adjustment, and the holes 22 of Figs. 1 and 3 are arranged in several series, the holes of all of the series radiating from a common center.

However, there may be a joint for permitting adjustment in vertical plane only, in

may be retained, except only one straight row of holes 22 will then be necessary; or the two joint-members may be L-shaped, and each member made up of two cylinders (1616 and 17l7), all open at the outer end. In this latter case, one openended cylinder of each joint-member (as cylinders 16" and 17") are fitted, and secured, as by rivets, to the reduced neck 15 and to the supporting-tube 18 respectively; and the other two open-ended cylinders (16 and 17) are loosely telescoped, one into the other, the outer telescoped cylinder (as 17) being provided with a housing 19' fora spring-pressed plunger rod 20 with a knob' 21, and the innertelescoped cylinder (as 16') being provided with a straight row of holes 22 for receiving the lower end of the plunger-rod.

For operation of either modification: The outer or rear end of tube 18 is telescoped upon the nozzle of the device that delivers the stream of heated air, and is secured thereto by means of the. snap-spring arrangement 24 or its equivalent; the customers head is then inserted into the inverted trough of the hood, the position of the latter being adjusted (if necessary) by means of the joint; and the customer rests her forehead against the sanitary brim 13, for shielding her eyes and face from the stream of heated air. The stream of heated air is then admitted into tube 18 and the hood; whereupon, by means of the deflector 23, the stream is directed and focused (as it were) toward the portions of the head where the hair is usually heavier (namely, the napeand back of the head) and is diverted away from the top of the head, where usually the hair is less heavy. It will be noted that the weight of my structure is not borne at all by the head of the patron being treated, but the weight is borne entirely by the supporting-rod 18, which in, turn is supported by the device that delivers the stream of heated air.

Since certain changes may be .made in the above construction and difierent embodiments of the invention could be made without departing from the scope thereof it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative'and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope ofthe invention which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new-and desire to secure by Letters Patent, is:

1. A hair-drying hood, comprising a longitudinally extended inverted troughlike member having at its rear end means to introduce a gaseous drying medium in a generally longitudinal direction, and having at its forward end a rim adapted to fit against the forehead and sides of the head of a subject, said trough-like member providing a space above and at the side of the subjects head to permit gases projected at its rear end to dry the subjects hair, and providing an outlet space at the rear of the subj ects neck.

2. A hair-drying hood, comprising a longitudinally extending cylindrical member having an open bottom, a generally semispherical member positioned at the rear of said cylindrical member and equipped with means to introduce'a gaseous drying medium in a generally longitudinal direc tion, and a forward member comprising an outwardly curved cap-like portion and a lower portion formed with a rim adapted to frame the head of a subject, said cylindrical member being of suflicient length so that the subjects head occupies only the forward portion of the opening therein.

3. A hair-drying hood, comprising a longitudinally extended inverted troughlike member having at its rear end means to introduce a gaseous drying medium in a generally longitudinal direction and having at its forward end a forehead rim disposed substantially centrally of the top and bottom portions of the device and side rims extending downwardly and rearwardly from said forehead rim and adapted to co operate therewith in framing the face of the subject, whereby there is provided a hood having a space above and at the rear of the subjects head to permit gases projected at its rear end to dry the hair of the subject and an outlet space at the rear of the subjects neck. 1

4. A hair-drying hood, comprising a longitudinally extended inverted troughlike member having at its rear end means to introduce a gaseous drying medium in a generally longitudinal direction, and having at its forward end a rim formed of a material which is a relatively poor conductor of heat, said rim being adapted to fit against the forehead and sides of the head of a subject, said trough-like member providing a space above and at the side of the subjects head to permit gases projected at its rear end to dry the subjects hair and providing an outlet space at the rear of the subjects neck. I g

5. A hair-drying hood, comprising a longitudinally extended inverted troughlike member having at its rear end means to introduce a gaseous drying medium in a generally longitudinal direction, and means'to deflect the projected air laterally and downwardly and having at its forward end a rim adapted to fit againstthe forehead and sides ion llll
