Orton, Akron, Ohio Application February 3, 1932, 'saglailgno. 590,112 2Claims. (01. 34-26) each hood is drawn therefrom by suction and The present invention relates to a hair drying returned to the casing 10. apparatus, primarily intended for use in beauty Arranged between the sections of the respec parlors, and comprehends a construction where tive pipes II and I2 for each hood is a valve cas by a number of persons can be attended to at the 5 same time. Accordingly, the invention provides a plurality ing IS in which operates a suitable valve for both regulating the ?ow of heated air to the par ticular hood, as well as to control the admission of such air thereinto either at the top or adja of head receiving hoods into which hot air is admitted for the hair drying operation, each cent the bottom of the hood. _ hood being associated with inlet and outlet pipes For this purpose each hood is of special con 10 through which the air passes by suction. struction, including spaced inner and ‘outer walls 10 In carrying out the invention each hood is l1 and l8 respectively de?ning an air receiving especially constructed and equipped with a valve chamber l9 by the intervening space therebe for regulating the ?ow of heated air into the tween. These walls are connected at their lower hood, either at the top whom a point adjacent ends by a wall 20 which closes the chamber at 15 this end. The wall I‘! is provided with a series 15 the bottom thereof. The nature and advantages of the invention of openings 2| adjacent its lower edge through will be better understood when the following de which communication is established between the tail description is read in connection with the hood proper and the chamber IS. The outer wall accompanying drawings, the invention resid I8 is formed with a neck 22 arranged in spaced r ing in the construction, combination and ar 20 concentric relation about the adjacent section rangement of parts as claimed. of the pipe II which is connected with the inner In the drawings forming partof this applica wall the top of the hood.

When used in this Figure 7 is a section showing the cut o?‘ posi tion of the valve. 35 ‘ V Figure 8 is a bottom plan view thereof. Figure 9 is a section on line 9--9 of Figure 3. The apparatus essentially embodies a casing l0 . in which the air employed is heated in any suit able manner and conveyed therefrom through a 40 sectional pipe l I. There are a plurality of these pipes all arranged in spaced horizontal relation and lead from the top of the casing H) as illus trated. The pipes ll successively vary in length as shown in Figure 2 thereby locating the head 46 receiving hoods supported by the outer ends of these pipes in spaced relation, so that a number of persons can be attendedv to at the same time. Each hood is also provided with a sectional re ‘ turn pipe l2, which is preferably arranged di rectly beneath its pipe ll, while all of the return pipes l2 communicate with the casing l0 through a manifold l3. The manifold is equipped with a suction fan of any suitable type indicated gener ally at I4 and driven from a motor l5. By virtue the heated air ?owing to ‘ of this construction manner, the heated air is directed on the top <0 of the head of the person wearing the hood, and 35 of course works its way to~the scalp. However, the hair can be more effectively and quickly. dried by intermittently directing the heated air close to the scalp and allow such air to work its way up through the hair before leaving the hood. 40 Consequently by adjusting the valve above re-. ferred to, the heated air can be conveyed to the chamber 23 through pipe 12, from where it passes into chamber l9, escapingthrough openings 2| into 'the hood proper adjacent the lower end 45 thereof. As this air passes upwardly through the hair it ?ows from the hood through the adjacent section of pipe II, thence through the valve into the return pipe l2. The valve can vary in construction for the pur 50 poses above stated, but, as shown, embodies a hollow rotatable cylinder 24 mounted in the casing Hi. This valve cylinder is provided adjacent its upper end with three openings 25, 26 and 2‘!v equidistantly spaced apart in the same horizontal 2 2,040,268 plane, while it is also provided with an opening 28 adjacent its lower end. Located within the valve cylinder adjacent its lower end and at a right angle to the opening 28 is a tube 29, the latter opening at diametrically opposite sides of the valve cylinder. Arranged above this tube 29 is a curved tube 30 disposed at a right angle to the tube 29, with one end opening at one side of the valve cylinder adjacent the bottom thereof, 10 while its other end opens at the opposite side of the cylinder adjacent the top thereof. A valve operating rod 3| depends beneath the valve cas ing l6 and is provided with an indicating ?nger 32 to indicate the position of the valve and c0 15 operate with stop pins 33. In practice, when the valve is positioned as il lustrated in Figure 3, the opening 26 communi cates with one section of the inlet pipe I l to admit heated air into the valve cylinder, but as the tube 20 30 occupies a position to prohibit the passage of this air through the other section of the pipe II, the air is forced to pass through the lower opening 28 into the adjacent section of the pipe l2. The air is thus delivered into the chamber 23 which communicates with the chamber l9 and ?nally enters the hood from points adja» cent the bottom thereof through the openings 2|. As stated, this use of the apparatus directs the heated air close to the scalp and allows the air 30 to flow upwardly through the hair, and pass from the hood through the adjacent section of pipe I I. As shown in Figure 3, this section of the pipe communicates with the curved tube 33 which de livers the air to the return pipe I 2. By rotating the valve cylinder one quarter of a turn to the right, from the position it occupies in Figure 3, it assumes the position illustrated in Figure 4. In this View it will be noted that open ings 25 and 21 of the valve cylinder establishes communication between the respective pipe sec tions ll, so that the heated air will pass through effectively and quickly dried than by use of present day methods. While it is believed that from the foregoing description the nature and advantages of the in vention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein illustrated or described and that such changes may be resorted to when desired as fall Within the scope of what is claimed. What is claimed is: - I 1. A hair drier comprising parallel hot air and cold air conduits, means for forcing air from said cold air conduit and hot air to said hot air con duit, a hair drying hood having spaced inner and outer walls, said inner wall of the hood hav 10 ing openings therethrough adjacent its lower edge, means connecting the top of said hood with said cold air conduit and with the latter nor mally communicating directly with the space be— tween the inner and outer, Walls of said hood, 20 means connecting the top of said hood with said hot air conduit and with the latter normally communicating directly with the interior of said hood, and a reversing and shut-01f valve between said conduits and said hood, said valve being operable to place the cold air conduit in direct 25 communication with the interior of the hood and simultaneously place the hot air conduit in di rect communication with the space between the inner and outer walls of said hood, at will. 2. A hair drier comprising a hood having a chamber therein adapted to receive a portion of the head of a person, a ?rst air conduit communi cating with said chamber in said hood,'a second air conduit communicating with said chamber in 5‘ said hood, air heating means, air moving means, means to conduct air to said air moving means, means to conduct air away from said air moving means, adjustable means between said hood and said air moving means which in one position es these pipe sections directly into the top of the tablishes communication between said ?rst air 40 hood. At the same time tube 29 assumes a posi tion to establish communication between the re spective sections of pipe l2 so that after the conduit and said means to conduct air to said moving means and also between said second air conduit and said means to conduct air away from said air moving means and which in an heated air escapes from the hood through open ings 2! into chamber I9, it enters the return pipe and is conveyed to the casing ID by suction. By shifting the valve cylinder to the position it oc cupies in Figure 9 all communication is cut off between the sections of pipes II and I2 respec tively. The apparatus can be economically oper ated and easily manipulated, and by virtue of its construction a number of persons can be at 55 tended to at the same time and the hair more other position establishes communication be tween said ?rst air conduit and said means to conduct air away from said air moving means and also between said second air conduit and said means to conduct air to said air moving . means, so that said ?rst and second conduits act alternately as incoming and exhaust air conduits and whereby the direction of ?ow of air through said hood is reversed.
