11 Claims. (01. 34-400) This invention is in hair driers, and particularly in driers of the helmet type, used largely in beauty shops. It is an improvement over the construction shown and .described in my earlier application Serial No. 236,092, filed October 20, 1938.

The principal object of the invention is to efiect the drying of the hair by passing air through rather than over the .hair, and at temperatures much lower than those necessary with hair driers now commonly in use. To this end, the air is delivered as far as possible beneath the body of the hair, and is drawn or sucked through, rather than circulated around, the body of the hair, thus causing a very rapid drying effect.

The invention includes anupper helmet proper, and a lower cooperating section. This lower section comprises anumber of tubes or channels movably cooperating with the lower edge of the helmet proper, which tubes or channels are flexible or adjustable, :so that they may be moved away from and toward the head of the customer, and yet deliver the air as near .to the scalp as convenient. They thus constitute a closure .for

the bottom of the helmet, which closure fits snugly the head of the customer, and adjusts itself to heads of varying sizes and shapes.

These delivery tubes as a whole are covered with some flexible or elastic material, so as to 'close the spaces around and between the tubes;

and this covering is made to fit the head of the customer so as to prevent substantial leakage of air'around the same.

By this arrangement, the drying air is delivered where most needed, and at the .same time discharge of heated air over the vface and body, with its great discomfort and inconvenience to the customer, is entirelyavoided.

This arrangement, while closely-enclosing the head, actually leaves the head relatively free, so that, within reasonable limits, it can be moved with freedom, to the ease and comfort of the customer.

drier, but show- Referring to the drawings in detail, the numeral J0 represents the top of .the helmet, which may be of metal, vulcanite, orany othersuitable material. To the lower edge of this top, there are pivotally secured hollow arms or tubes 1 I, which together constitute the bottom or adjustable portion of the drier. Around the lower portion of the helmet top III is a chamber l2, in which is arranged a heater .l3 by which the temperature of the air may be raised, if and whenheated air is desired. A-suction outlet is adjustably arranged in the top ID, as will be more fully described hereinafter.

The upper part 10 of the helmet is merely a covering of sufiicient strength and of satisfactory material to provide a suitable recess to receive the top of the head. Itis notintended to closely fit the head, but on the other handshould not be unduly large; a sufficient .space to proyide room for the head and leave a reasonable space around the. same is all that 'is necessary.

The air delivery tubes "I l, which together form the lower part of the structure, are sufficient .in number to surround the head of .the customer. The number may vary considerably, but if the number is too small, the tubes will not closely fit around the head; and if the number is too large, the structure wil be unnecessarily complicated. In Fig. 2, twenty such tubesare shown, but this number is merely illustrative, for any desired number may be used.

Referring more particularly to Fig. 4, whic shows one of the tubes |I,.and means for operating the same, somewhat enlarged, the tube has its outer end extending through and pivotally mounted in the lower part of i the chamber 12, tube in constant communication with. the interior. thereof. The inner end .of the tube has a soft rubber closure 15, by which it may rest against the head of the user,.and one or a plurality of openings I6, at or near the inner end, for the escape of the circulating air. These tubes must be mounted in chamber 12 for swinging movement, and so are hingedor otherwise pivoted therein. As here shown, the outer end of eachtube is flanged as at H, so that it may tilt or turn on the inner side of thechamber, as by hinge I8.

The tubes 1! are forced toward the head, as shown in .E'ig. 3, by springs 20, which must have sufficient strength tomove the tubes, but .which can be easily overcome in practice. These springs 2!! are hereshown arranged within the chamber !2. Each tube ll is operated by a pin or rod .21, movable .in the top and bottom of the chamber 12; Each-pinZI carries a flange 22, and passes through its cooperating spring 20. The spring is confined between the bottom of the chamber 12 .andthe flange 22, and lifts the pin until the flange 22 rests beneath the top of the chamber I2, unless the inner end of the tube or its closure I5 is sooner stopped by contacting the head of the user. The lower end of the pin is pivotally secured to a link 23, which is pivoted to the sides of its cooperating tube The pin 2| is normally held raised by its spring 20, and in turn lifts its tube II, and holds it in its elevated position, as shown in full lines in Fig. 4, or against the head, as shown in Fig. 3. Depression of the pins 2| compresses the springs 20, and causes the tubes II to pivot at their tops, and open out as shown in broken lines in Fig. 4. On release of pressure on the pins 2|, the springs lift the pins, and through links 23, restore the tubes II to the full line position of Fig. 3.

The pins 2| may be depressed one by one manually by pressure on their tops, but obviously, for practical purposes, all pins should be depressed together, so that all of the tubes II will open out simultaneously for application of the helmet to, and its removal from, the head of the customer. For simultaneous operation, a ring or band 24 is shown applied to the tops of all the pins 2|. Pressure on this ring, as by grasping this ring and the lower edge of the chamber l2 with one hand on either side, compresses all springs 20 at one time and moves all tubes simultaneously, thus making easy the placement of the helmet and its removal from the head. The pins 2| are not secured to the ring 24, but the ring merely rests on the tops thereof. This, or some equivalent arrangement, is necessary in order that the pins 2| may be operated as required by the positions of the tubes some of which willhave to move farther than others, depending on the shape and size of the head of the user. To provide for this independent movement, the ring 24 is provided with a series of tubular extensions 25, within which the pins 2| move with an easy or loose fit.

The annular chamber l2, in its upper portion, or elsewhere in its surface, is provided with a series of openings 26. for the admission of air. The heater |'3 is immediately beneath these openings. Any type of heater may be used, but as here shown it comprises an electrical heating element mounted and connected in circuit in any convenient way.

The top H! of the helmet. at some conven ent point, is provided with an opening 3!], by which the outlet M is connected to the exhaust tube The outlet I4 may be a mere couplin but preferably it is a tube which may he slipped more or less into the helmet, so that the inner end thereof can be placed close to. or moved farther away from, the crown of the head. If the inner end is placed close to the hair. it will accentuate the movement of the a r through the hair, whereas, if it is moved farther away, more air will pass over the hair than through the ha r. Thus, by adjustin this tube or couplin l4. toward or away from the top of the head, the flow of air through the hair can be varied at will. As here shown, this element !4 is merely slipped through the top of the helmet, but any other means of adjustment may be employed.

The tubes H are covered by some suitable woven or elastic material 35. If woven fabric is used, the inner edge 35 should be plaited, as at 31, to permit the ready opening and closing of the tubes II. If rubber is used for this purpose, it need not be plaited, for it will yield sufficiently to adjust itself as the tubes are opened or closed.

In the form here shown, each tube H is provided at its lower end with a projection or other fastening 28, to which the cover may be secured, but of course the cover may be secured in place in any suitable manner.

Current for the heater may be supplied in any convenient way, as by conductor 38, and controlled by any suitable switch.

Operation In using the drier, the operator grasps the ring 24, and the margin of the annular chamber l2, and with one side in one hand and the other side in the other hand, depresses the ring 24, thus depressing all pins 2|, compressing all springs 20, and opening out all tubes II, as shown in broken lines, Fig. 4. The helmet, thus opened, is then placed over the head of the customer. Upon releasing this pressure, the tubes move inward, under the action of the springs 20, and embrace the head with a light pressure. The covering 35 closes the openings between the tubes II, and also fits the head of the user sufficiently to prevent undue leakage of air. While this is not an air tight connection, particularly around the head, it is suificiently close for all practical purposes.

Suction is now applied through the coupling M and tube 32. Air is thus drawn in through the openings 26 of the annular chamber I2, over and around the heater |3, which may or may not be in heated condition, and through the tubes The air passes out the openings l6, which are preferably arranged to discharge beneath the body of the hair and close to the scalp, as best shown in Fig. 3. The coupling I4 is set close to but preferably not in contact with the hair. As the exhaust is applied, the air tends to flow up through the hair, rather than merely over the surface thereof, and out the suction hose 32. This applies the air in the most effective manner, and where it is most needed.

The heater l3 may or may not be used, depending largely upon the condition of the external air. If the air is very dry, the heater may not be needed; if its moisture content is high, that is, if it is humid, the heater will probably be necessary.

No air is blown down over the face and body of the customer, and the very disagreeable effect of a blast of hot moist air for a long period of time is entirely avoided. At the same time, the application of air at or below the bottom of the hair, and its circulation by suction, rather than by pressure from behind, makes the drying very rapid and effective. Any degree of suction, that is, reduced pressure in the helmet, may be used, but preferably the reduced pressure is just sufficient to cause rapid movement of the air, but not sufiicient to disturb the hair.

The use of a suction device, of course slightly lowers the air pressure within the helmet, and this to some extent tends to bring the blood to the surface of the skin, thus stimulating the scalp.

The illustration is the best form of the drier now known, but it is to be understood that I am not limited to the exact form or proportion of parts here shown.
