HAIR WAVING APPLIANCE
Max Gottlieb, Chicago, Ill.
Application March 2, 1936, Serial No. 66,685
5 Claims.
My invention relates to hair curling appliances
and in one form of its use is particularly of value
in connection with what is called permanent wav
ing of hair.
5
' My invention is designed to provide instrumen
talities by virtue of which a more thorough and
uniform curling of the hair is made possible.
By
the use of these instrumentalities it ‘is possible
to reduce the length of the uncurled hair ad
ja‘cent to the scalp and it is also possible to pro
vide a more uniform curl, that is, one in which
the difference between the length of each wave
is reduced, that is my improved device separates
the strands of hair to a greater degree than has
heretofore been possible so that each strand when
Wound upon a mandrel does not have as large an
2
outer diameter as is customary in the present
devices. Thus the wave in the outer layers of
the hair more nearly approximates the length‘
of wave of the inner layers.
It is another object of my invention to arrange
a device of this nature which can be used with
the standard heating appliances that are mount
ed above the curling elements after the curling
25 elements are in place, that is, my improved de
vice although providing for two strands of hair
in connection with each device, nevertheless is of
such a size that it would fit the standard heating
unit as used in connection with other devices hav
30 ing but a single mandrel or curling element.
A further advantage which accrues due to the
use of my invention is that it takes less time for
the steam or other heating means to penetrate
the wound strand, and if steam is used, it more
readily penetrates to the interior because of the
smaller diameter of the curled strand.
In accordance with my invention I provide an
instrumentality of this type in which two strands
of hair may be accommodated and I so arrange
40 this instrumentality so that it may be opened to
receive the hair, and locked to clamp the same
in position even though the instrumentality is
placed immediately adjacent another like instru
mentality in which-other strands of hair have

Fig. 6 is a perspective view of the underlying
pad; and
Fig. '7 is a sectional view on line ‘I of the ex
tremity of one of the mandrels.
Referring more particularly to Fig. 4, I show 5
there my improved clamping device which con
sists of a back plate III to which three clamping
elements I I, I2 and I3 are pivotally mounted,
although the central element is preferably sta
tionarily arranged as shown. The clamping ele
ments as shown more clearly in Fig. 3 comprise
central metallic portions I4 surrounded by rubber
envelopes I5. The back plate I0 is preferably an
L-shaped element having upwardly projecting
?ngers I6, I‘! and IS, the slots between the ?ngers 15
furnishing a guide for the extremities of mandrels
I9. The right hand extremity of the clamping
element I3 (Fig. 4) is provided with a locking de
vice pivotally mounted thereon which consists
of an upper front plate 20 and a lower front plate 20
2|. The upper front plate 20 is likewise pro
vided with three ?ngers, respectively the ?ngers
22, 23 and 24 which serve a purpose similar to
the ?ngers I6, I1 and I8 in that they accommo
date the opposite extremities of the mandrels 25
from that accommodated by the ?ngers I6, I‘!
and I8.
The right hand extremity 25 of the clamping
element I2 is ?at so that it may enter between
the two plates 20 and H and the same is true of 30
the right hand extremity 26 of the clamping ele
ment I I.
Between the upper and lower plates 20 and 2|
of the locking device there is mounted a lever 21
having an eccentric 28. Thus when the three 35
clamping elements II, I2 and I3 are pressed to
gether as shown in Fig. 1, then the lever 27 may
be swung in a contra-clockwise direction (Fig. 4)
and the eccentric 28 ?nds its position in the round
side portion 27' of the element 26 and locks the 40
three clamping elements together as shown more
clearly in Fig. 1.
It is of course to be understood that two strands
of hair are ?rst to be inserted between the clamp

I will describe one form which my invention
may take more in detail by referring to the ac
ing shown more clearly at 29 and 30 in Fig. 3.
My improved device, as before stated, is no

device which is used as a basis for the drawing
the width of the device roughly is a little better
than one inch.

Before the two strands of hair are introduced
between the clamping elements ll, l2 and I3,
they are drawn through a pad 3|, which pad
preferably consists of a felt portion' 32 and a
rubber or rubberized portion 33, this pad having
two slots 34 and 35 through which the strands
are initially drawn and the pad placed against
the scalp. These pads are separate from the
clamping device or element.

From what has been described it will be seen
that if a device of this nature is used in which
the total amount of hair which is to be curled and
which is drawn from beneath the device is di
vided into two strands, that the length of. the
uncurled hair adjacent to the scalp is consider
ably less than if the hair were drawn through
such a device in one strand only. Two strands
likewise make it possible to have a wound strand
In use therefore, the two strands of hair are .. of less~diameter than if all of the hair is wound 10
drawn through slots 34 and 35 and then inserted
in a single strand.
between the clamping elements ll, l2 and I3,
improved devices I can utilize more on a scalp
whereupon the clamping elements are locked to— .
gether. The free extremities of the two strands
15 are then wound upon two mandrels I9, 19 and
as the hair is being wound upon these mandrels,
the mandrels approach closer to the clamping
I ?nd that by the use of my
gvthan?with the older type of devices.
From) what has been thus described, it is
thoughtthat the nature of my invention will be
readily. clear .to those skilled in the art. Having,
however, thus described one form which my in
element until ?nally their opposite extremities - vention may. take, what I claim as new and desire
pass into the slots between the ?ngers l6, l1, I8,.. to secure by Letters Patent is:
l. A device for use in the permanent waving
20 22, 23 and 24, respectively. These mandrels are
each provided with a ?nger 36 to thoroughly hold . of hair ‘and adapted to clamp strands of hair
the extremities of the strand. Each mandrel‘ I9
has as shown in Fig. 7 a round projecting portion
31 and a square portion .38. These form part of
25 aplate 39 held in the extremity of the mandrel
and so arranged that the parts 31, 38 and 39 can
rotate relatively to the mandrel H? in one direc
tion only. The opposite extremity of each man
drel has a knurled ?nger piece 40 ?xedly'attached
30 to the mandrel and as the mandrel approaches the
slots between the ?ngers the elements 31 and 42,
- both'being round, permit continuous rotation of
the mandrel. until it approaches the position
shown in Fig. 3, whereupon the mandrel is pushed
to the right (Fig. 1) so that the squared portion

ments mounted together, and means operable at
‘one side thereof for locking said clamping ele

ments together.
2. A device for use in the permanent waving
of hair and adapted to clamp strands of hair
therein comprising three separable clamping ele
ments, an end plate to which said elements are
mounted, two of said elements having swinging
engagement with said end plate, and a unitary
locking device carried by the opposite extremity
of one of said elements for locking said elements
together.
.
3. A device for use in the permanent waving of 35
38 enters into the slot between the ?ngers to be ‘ hair and adapted to clamp strands of hair therein
there held while the mandrelvis further rotated in
order to tighten the strand upon the mandrel.
The locking instrumentalities shown in connection
40 with the mandrel prevent reverse rotation of the
mandrel after this ?nal tightening process.
In order to obtain a still tighter adjustment
of the mandrel, it is provided with a plurality of
holes 4! into which a small rod may be inserted
45 for that purpose, thus to obtain a greater leverage.
comprising three separable clamping elements
mounted together, means operable at one side
thereof for locking said clamping elements to—
gether, and an insulating pad having slots 40
through which said strands of hair are passed.
4. A device for use in the permanent waving
of hair and adapted to clamp strands of hair
therein comprising three separable clamping ele
ments, an end plate to which said elements are 45
To release the mandrel it is pushed to the left to 'mounted, ?ngers extending upwardly from said
release the square shaft portion from between ' end plate, two of said elements having swinging
the ?ngers.

engagement with said end plate, and a unitary
It will be seen that because the three clamping locking device carried by the opposite extremity
50 elements ll, l2 and I3 are clamped by means of r of one of said elements for locking said elements
a lever operated from one side thereof, that a
second clamping device may be mounted adjacent
to the onealready in position so that the two
may closely adjoin, all as shown more clearly in
65 Fig. 5.
I prefer to have the pads 3| overlap as shown
in Fig. 5 so as to be doubly safe in guarding the
scalp from the heat that is being applied from
the heating elements. It must be understood, of
60 course, that the drawing illustrating this overlap
ping arrangement in Fig. 5 is not exactly correct
together.
5. A device for use in the permanent waving
of hair and adapted to clamp strands of hair
therein comprising three separable clamping ele
ments, an end plate to which said elements are
,mounted, two of said elements having swinging
engagement with said end plate, a unitary locking
device carried by the opposite extremity of one
of said elements for locking said elements to 60
gether, and ?ngers projecting upwardly from said
locking device for accommodating mandrel ex
