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

of course works its way to~the scalp. However,

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
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:
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
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.
