also been experienced in securing proper distribu

head, thus causing the time required for the com

heating operations upon separate
groups of waving devices, in place of supplying a
complete set of waving devices with steam in

It is an object of the invention to provide a per
manent hair waving machine utilizing steam as a
source of heat, which will overcome the above
difficulties and which will make possible the heat
ing of an entire head of hairby steam in a
single
operation, in a simple and effective manner,
40
without discomfort to the subject. In connection
with the machine described herein, it is preferable
to utilize hair waving ‘devices of the type dis~
closed and claimed in Patent No. 1,984,585, grant
ed December 18, 1935, which are a marked im
provement over the cumbersome forms of stea
boxes utilized in the past.

Further objects of the invention will appear.

ferred embodiment of the invention has been set
forth in detail in conjunction with the accom
panying drawing.

Referring to the drawing:

steam is relatively dry. Where the pipe I2 com
municates with the vaporizing chamber, a suit
able valve is preferably provided, to be operated
by handle it. This valve is arranged to have two 30
operating positions, in one, of which the vaporiz
ing chamber is placed in communication with
both pipe l2 and an auxiliary steam exhaust con
duit I1, and in the other position of which the‘
auxiliary conduit I? is closed so that all steam 35
is discharged through pipe l2 and into the con
duit Ii.
In order to simultaneously apply the steam to a '
plurality of hair waving devices, ?exible tubes l8,
formed of a suitable material such as resilient 40
vulcanized rubber, communicate at circumferen
tially spaced points with the conduit ll . For ex
ample, as shown in Fig. 3, the end portion I9 of
each rubber tube I8 is enlarged and is slipped
over a stub tube 2|,which in turn communicates
with conduit H. -The tapered nature of the
enlarged resilient rubber portion l9 tends to pre
vent kinking of the tube [8, such as would ob
struct the same for ?ow of steam. All of these
tubes are preferably of the same length, toaf
