E. VOSS HAIR DRYING APPARATUS Filed March 28, 1925 PATENT. OFFICE.

ERDMANN VOSS, OF HAMBURG, GERMANY.

HAIR-DRYING APPARATUS.

Application filed March 28, 1925, Serial No. 19,061, and in Germany May 8, 1924.

My invention relates to an improved device or apparatus for drying the human hair by means of a heating operation and the obj ect of my invention is to provide an apparatus for the stated purpose, which allows of being adjusted to conform to the shape and size of the head of a person and which will act to distribute or spread the current of hot air employed as a heating agent, and to reduce or weaken the same so that the head of the person will be surrounded as it were, by a zone of hot dry air, whereas in all of the hair driers hitherto suggested or practised the hot air is ejected in the form of a more or less powerful current, acting to always strike a limited part or spot of the head only. My improved apparatus, therefore, is particularly adapted for use in drying hair which has been curled to form permanent waves, for the reason that the waves are not injured by the milddrying operation but will stay and keep in shape.

With the above recited and other objects in view the invention resides in the novel construction set forth in the following specification and illustrated in the accompanying drawing forming a part of this specification and showing for purposes of exemplification, a preferred form and manner in which my invention may be embodied and practised.

The Figure 1 of the drawing is a sectional view of the new drying ap aratus. Figure 2 is a view of a further modi cation. It comprises from a general aspect, a globular air conduction head a with a tubular inlet 5 for the attachment of a conduit connected with any suitable source of hot air supply, and with a clamping device a for connection with any appropriate stand or holder. Fitted to the sides of the head a in the manner of a ball to constitute, in co-operation with the latter,-

a kind of a ball and socket joint, the two shells at being held in permanent contact with the respective counter-faces of the head by means of a coiled spring 8 interposed therebetween,

.as will be readily understood on an inspection of the drawing.- 7

The arms thus have an extension freedom of movement with relation to the head, the more so since the circular openings in the wall of the head, through which the arms project from the latter, have a somewhat greater diameter than the arm portions f.

- The outer end of the part f of the arm is connected with a hot air shell or cup h by means of a coupling similar to that hereinbefore described. To this end the part f is provided with a spherical shell 9 engaging in a globular shell g connected to the cup h by means of a short-curved tube 1', the two shells gand 9 being kept in the required distance apart from each other by means of a coiled spring is so that there is extension freedom for the cup h to turn about the joint. Mounted in the cup I). is an inverted conical body 2' which has an enlarged base portion for distributing purposes as will be explained here inafter.

The operation of the apparatus is as follows:

Upon having adjusted the apparatus on the stand not shown by means of the clamp and screw c and in accordance with the stature .of the person, the inlet socket b is to be connected with the hot airconduit, not shown. The hot air then flows in the form of a current through the head a, the tubular arms f,

and the curved tubes r into the two cups h. The discharge of the hot air currents from the two cups 72., however, does not take place in a linear path or in the form of a current, but the shape of the cups and the configuration of the conical bodies therein have the effect of distributing or spreading the hot air current over a large area, whereby the energy or impact of the rushing hot airis reduced and the hair in its totality or the head of the person, is uniforml enfolded in a comparatively ca'lm zone-o drying hot air. In this manner the hair is dried without the necessity of employing protectingnets and without any liability of deranging or impairing dressed hair and particularly hair curled to form permanent waves.

From the foregoing it will be seen that the invention affords a means for adjusting the apparatus to the stature and size of the head of any person and fordrying the hair in a more reasonable manner than hitherto practised. It goes without saying that in some cases it Will be advisable to use more than two arms and cups or it may be sufficient to use only a single arm and a single spreading cup either by taking oflz' the one arm, when renection of the spreading cup h to the head or the arm or the arms supplying the hot air may be varied or simplified, by using an ordinary clamping device only. For while I have shown my invention embodied in a certain.

apparatus, it is not to be inferred that such apparatus represents the only form in which my invention may be embodied but is illustrated and described as illustration of a form now preferred by me and to make clear the principle and method of application of my invention- I therefore do not wish to be limited to the exact details of construction andarrangement shown and described, as modifications are no doubt possible, which would still come within the scope of the invention and the claims appended hereto.

What I claim is: j

1. An apparatus for drying the human hair by means of hot air, comprising a head adapted to be attached to a hot air conduit,

spreading on s, and telescopically composed tubes pivotal y attached to the said head and to the said cups, respectively.

2. The spreading cup having a conical spreadingbody attached 'to its inner surface gupistantially as shown, for the purpose speci- 3. An apparatus for drying the human hair by means of hot air, comprising'a head adapt 1 ed to be attached to a hot air conduit, spread-' ing cups, telescopic tubes, a spherical socket joint at the one end of each tube-for the connection with the said head, and a spherical socket joint at the other end of each tube for the connection with the two spreading cups,

respectively, substantially as and for the purpose set forth.

4:. An apparatus for drying human hair by means of hot air comprising a supply head to be attached to a hot air conduit, mouthpieces, distributing cones within the same, telescopically composed connecting tubes, and a spherical joint at one end of each tube for connection with the mouthp'ieces.

5. An apparatus for drying human hair by of the tubes for connection with the supply head and themouthpieces.

In testimony whereof I 'aflix my signature.
