My invention relates to hair drying, and hair waving apparatus in which hair is dried by a current'of heated air applied directly and locally to the hair to be treated. My invention is. applicable to apparatus for surrounding a bunch or wave of hair to be curled. the hair having been fi st moistened, or the moistened hair maybe wound on the apparatus, which serves as a core.

The hair is then heated by air applied by the apparatus to expel the moisture from to cause the curl to remain therein.

After human hair has been permanently waved, it is in short kinlrycurls which are undesirable from the esthetic viewpoint. The usual procedure is to comb. the dried hair to remove the kinks and then reset it by first wetting the hairwith a suitable lotion or solution, and then the hair and to arrange the hair in waves which are commonly referred to as finger waves. After the finger waves have been set over the desired portion of the head, the practice has been to subject the whole head of hair to a current of heated air expelled from a canopy in spaced relation to the head, and partly surrounding it. 'This drying takes a comparatively long period of time to thoroughly dry the hair and especially that part of it which is near the scalp. The outer part, which is exposed directly to the heated air dries fairly rapidly and then acts somewhat as an insulator to prevent drying of the underneath layers of hair. It takes a fairly considerable period oitime to dry the'hair under methods heretofore known, de= pending on the thickness of the customer's hair and the amount of hair waved at one operation.

My invention is of particular utility in drying the wetted or moistened finger waves and for forming wetted or moistened hair into curls. It is one of the objects of the invention to provide apparatus suited for rapid and thorough drying m of the hair and to reduce the time degree for this operation to a minimum.-

On certain parts of the head, it is cite advisable to form the hair in small diameter curls which are pinned into shape until dried, and one form of my invention is particularly useful for rapidly forming and drying these curls without the aid of pins to hold them in shape whil e drymg.

In the accompanying drawing, illustrating a n present preferred embodiment of my invention,

Figure 5 is a view partly in section and partly in elevation of still another form of apparatus constructed according to my invention; and

Figure 6 is a perspective view of a detail of the apparatus shown in Figure 5.

In Figures 1, 2 and 3 of the drawing there is shown a drying unit or wave dryer it which comprises an outer shell or tube ii of suitable dimensions made from suitable resilient material, preferably metal, adapted to enclose a launcher wave of hair. The sides of the tube ii are movable relative to each other and for that purpose are provided with expander portions iii and itwhich are secured to the top portion of the tube and which serve as handles. The bottom of the tube ii is divided along a serrated line it so that the sides of the tube form two co-operating'jaws which are movable away from and toward each other and will securely grip an object placed between them. The sides or the tube adjacent the serrated dividing line it have outlet openings it formed therein. Preferably these openings are formed by striking a portion it of the side wall outwardly as shown. Any other air outlet arrangement, such as holes along the sides of the tubes,'is also contemplated. The arrangement which I have described serves to allow air from the interior of the tube ii to escape in a mariner which will not cause it to impinge directly on the scalp of the person whose hair is being treated.

An air supply tube B?! is connected to the top portion of the tube ii and communicates with the interior thereof.. -The ends of the tube H are closed by overlapping plates or closure members it and is, secured to the sides oi the tube to form a drying chamber closed at both ends. It is desirable to overlap the end plates i8 and it so that when the tube is in an expanded position surrounding a wave or bunch of hair til as shown in Figure 2, the air will be constrained to flow througlithe hair andout the openings. 6 ii and thus cause the apparatus to be used in the most efficient manner in drying all parts of the hair enclosed by the tube. v

After the hair has been properly wetted and the desired finger wave placed therein, each wave is surrounded by a suitably located wave dryer it. Sufficient of the dryers are used to cover the desired number of waves. Heated air is then introduced through the tube i l, and

ill

- referred to as button curls. The apparatus con-- thence through tube II and allowed to escape through the openings I5 to dry the hair.

In Figure 4 of the drawing there is shown a curler and dryer constructed according to my invention by means of which a strand of hair can be rapidly curled and dried. The apparatus consists of a pair of semi-cylindrical levers or members 2i and 22 connected together adjacent one end by a pivot pin 23 so as to form a cylindrical tube. The levers are movable relative to each other in scissor-like fashion and for that'purpose are provided with expander portions or handles 24 and 25. The levers 2i and 22 are preferably formed from metal, but any other suitable material may be satisfactorily employed. Along each of the levers 2| and 22, outlet openings 26 are provided of various sizes and shapes. In Figure 4, rectangular openings are illustrated. A stopper 21 is rotatably secured on the end of arms 28, the opposite end of the arms being pivotally secured in a ring 29 which is rotatably secured to the handles 24 and 25 by projecting lugs 30 and 3|. The arrangement is such that the stopper 21 may be swung from the position shown in full lines in Figure 4 to the position shown in dotted lines in that figure where the stopper 21- closes the end of the chamber formed by levers 2| and 22. Air from the interior of the apparatus will then be compelled to pass outwardly through the openings 26.

An air supply tube air at an appropriate temperature and pressure into the chamber formed by the co-operating semi-circularlevers 24 and 25. when a strand of hair is to be waved, the levers 24 and 25, are spread apart and retracted to seize the strand of hair between its edges and the hair is wound on the cylinder formed by the levers 24 and 25 to the desired extent. The arms 28 are swung from the full line position to the dotted. line positi n and serve to hold the hair and the curler in sition, while the stopper 2'! is inserted inthe. open end of the levers 24 and 25 opposite the handle end. The heated airis then passed} through tube 32 into the chamber formed by.

the levers 24 and 25 and-out the openings 25,

and dries the hair which is curled around the levers 24 and 25.

In Figures 5 and 6 there is illustrated a device for forming small curls which are sometimes sists of a circular disc 33 having upstanding pro-- jections 34 disposed thereon. An air supply cylindrical tube 35 is secured to the disc andthe end closed thereby. In the bottom part of the tube 35 a series of openings. 35 are arranged.

Fitting over the tube 35 is a cap member 31. This cap member has a sleeve portion 33 which closely fits around the tube 35 and an enlarged cup-shaped portion 39 which is of sumcient diameter to fit loosely around the disc 33 and of suflicient depth to accommodate the upstanding projections 34. Holes" are arranged around the sides of the cup-shaped portion 35, as illustrated.

In use a strand of hair is wetted to the desired degree and then is wound around'the tube 35. after which the coil of hair is pressed downwardlyagain'st disc 33 by means of the cap member 31 which, when in the curling position, assumes the position shown in dotted lines in Figure 5. The projections 34 help to keep the curl in position.

In the different forms'of the apparatus herein shown, after the hair is positioned, heated air from a suitable source (not shown) and at a 'de- 32 is disposed so as to lead' amuse and easily placed in position on and removed from the hair, so that hair dressing is facilitated,

and the person whosehair is being treated is subjected to a minimum of discomfort.
