(Cl. 132-361)
The present invention relates to spacers for
hair curlers. It relates more particularly to a
type of spacers that employs rubber sleeves and
has for its general object theprovision of a spacer
that shall be light in weight and efficacious in
use.
I
One type of spacer now in common use com
prises a pair of clamping bars hingedly connected
at one end and releasably connectable at the
10 other end and rubber sleeves on _said bars. These
rubber sleeves are sometimes provided with two
oppositely -disposed hair gripping faces or jaws
either of which may be used, after the other be
15
ed to facilitate sliding the sleeve on and oil' of
the clamping bars.
It is also an object of this invention to provide
a rubber sleeve with a metal lining capable of
giving a desired area of bearing surface against 5
the sleeve ‘without increasing the thickness of
the clamping bar on which the lined- sleeve is
placed.
’
.
It is a further purpose of this invention to pro
vide a rubber sleeve for clamping bars of spacers 10
for hair -curlers with a metal -lining which acts
as a reenforcement for the clamping bar itself.
The invention further contemplates as one of
comes useless, by turning or reversing. '
its objects the provision of a rubber sleeve for
the clamping bars of spacers for hair curlers with 15
fastened to a curler, and the lhair is wound upon.
The provision of a spacer having a pressureat
tachable and detachable connecting and clamp
In producing a curl, a bunch of hair from a.
section of the head is clamped by a spacer close ' a lininghaving divergent projecting corners and
to the head. The end of this bunch of hair is a channeled seat for the rubber bearing.
the curler until the curler rests upon the spacer
20 ‘and until the hair, which is elastic, is tightly
stressed around the curler.
'
A ratchet-like mechanism prevents the curler
from turning backward, and, if the hair is se
curely held by the spacer, it is maintained in itsI
25 stressed state while being treated with solution
and heat and a good curl is produced, but, if the
tension on the hair is lost, whether by slipping
through the spacer jaws or by causing the sleeve
to turn on the bar, the curl will be unsatisfactory
and what is known as a “pull-burn” may occur.
Due to the oil, heat and pressure to which they
are subjected in use, rubber sleeves frequently
become so distorted or damaged that they will
no longer hold the hair securely, and, when a rub
35 ber sleeve is used in contact with the metal bar
so
of a spacer, the rubber may adhere to the bar so
tightly that it may be difficult, if not impossible,
to slide it off without irreparably damaging it.
The area of the surface of a bar or liner that
40 bears against the rubber sleeve- should be great
enough to produce sumcient’pressure upon the
hair to securely hold it, without injuriously dis
torting and damaging the rubber sleeve. A bar
of sufllcient thickness to provide the necessary
area, if of sufficient width to withstand the pres
sure, would be undesirably heavy. My improved
construction not only provides any desired area
and a thin, light bar, but also provides af‘channel
into which the rubber bearing is seated to prevent
the rubber sleeve from turning and to reduce the
pressure 'necessary to hold -the hair and the con-'
sequent injury to the rubber.>
One object of this invention is the provision
inel spacerfor hairM curlers of a rubber sleeve
having a flexible compressible metal lining adapt
ing link and the provision of 'a slidably removable 90
and replaceable resilient sleeve having a metal
lining therein, as an article of manufacture,
whereby said lined sleeve may be removed and
reversedor replaced by >a new lined sleeve, with
out the use of a screwdriver, Wrench, or other 25
tool, are particular objects of the present inven
tion.
The features and advantages of the invention
will morev clearly appear from the following de
scriptìon, reference being had to the accompany- 30
ing drawing wherein a preferred form of the
invention is shown. It is to b_e understood, how
ever. that the drawing and description are illus

Referring nowin detail'to the drawing,- the
spacer consists of a pair of bars 6 and 1 which
are secured together at one end by hinge-link g* _
to which bar> 6v is rigidly fastened by tight rivets”
l 9 and l2 and to which bar ‘I is pivoted by means 55
2
2,136,196I
of loose rivet I8.
The link 8 is provided with
a bracket I I adapted to receive and support one
end of a curler on which hair is wound. The
link 8 is preferably made up of two pieces 8a
and 8b, which are held together by tight rivets
9 and I2 and pivot-rivet IIJ so as to form a uni
tary structure.
,
The bar 6 has a lined rubber sleeve thereon,
and the bar 1 has a similar lined rubber sleeve
10 thereon. These sleeves are provided for the pur
pose of receiving and gripping the hair there
between as will be readily lunderstood. The rub
ber portions of these sleeves are indicated by the
numerals I3 and I4.
At its free end, the bar 6 normally has attached
thereto a, connecting and clamping link I5, which
comprises upper and lower members I6 and I1
respectively, which are spaced apart to receive
clamping and locking cam 20 and bars 6 and 1
20 and which are held in’their relative positions by
rivets 2| and 2_3.
'
The upper member I 6 is providedwith a brack
v' et I8 adapted to receive andy support the other
end of said curler.
25
'I'he bar 6 adjacent its free end is provided
with a slot 24 in the edge thereof, and the bar
1 adjacent its free end is provided with a notch
or recess I9 in the outer edge thereof. The free
‘ end of bar 6 is between members I6 and I1, and
the spacing rivet 23 engages slot 24 when link I5
is attached to bar 6.
.
The recess I9 is adapted to receive' and form
faces 21 and 28».
'I'he rubber between these faces
and the adjacent faces 29 and 30 of the lining
25 is thickened at the center. To receive this
thickened part of the rubber, the faces 29 and
30 of the »metal lining 25 are depressed to form
a longitudinal channel.
'
'I‘he lining 25 has projecting corners 3l and
32 and has its flat sides 33, 34, 28, and 38 pressed
inwardly to slidably ,engage the sides and edges
of the bar. A plurality of ribs 35, 36, 31, and 38 l0
run lengthwise on the interior surfaces of the
rubber sleeves I3 and I4. These ribs resist the
tendency of the rubber to turn on the lining and
space the rubber from the flat sides 33 and 34
of the metallic linings 25 thus providing air spaces
throughout the length of the rubber sleeves I3
and I4 for heat insulating purposes.
When the hair is clamped between the rubber
sleeves I3 and I4, said thickened portions of said
sleeves and said projecting corners resist any 20
forces tending to move them out of engagement
with the depressed faces 29 and 38 of their lin
ings.
‘
`
The removal of the lined sleeves for the pur
pose of reversing or replacing them when they 25
become damaged in some fashion is made very
convenient with the present structure. Obvi
ously, the linedfsleeve upon the bar 1 may be
removed when the spacer is open.
In order to remove the lined sleeve from the- 30
~ bar 6, however, it becomes necessary to remove ~
the link I5 from this bar.
This removal is ac
' a fulcrum for cam 20 that is pivotally mounted.- complx'shed by pressing the end of the link I5,
in the link I5 by means of rivet 2|. A lever or
finger piece 22 by which the cam is actuated is
formed integral with cam 28.
To clamp the hair between bars 6 and 1 and
the lined sleeves thereon, the link I5 is swung
on pivot rivet 23 into a position in which cam
40 2G will engage the recess I9, when the finger
piece 22 is turned on pivot-rivet 2I in a counter
clockwise direction to the position shown in Fig
ure l where it is effectively held because the
line of force between rivets 2I and 23 is moved
past the bearing point of cam 20. The force
tending to spread the bars 6 and 'I when they are
clamped together is then utilized to oppose re
lease of the cam 20.
which carries rivet 23, endwise against the pro
jecting portion 26 o-f the rubber sleeve I3, with
the lingers andwithout the use of a tool, until
the rivet 23 is forced out of the slot 24, as shown
in Fig. 5.
'
After the lined sleeve has been removed and
reversed or replaced as desired, thelink I5 can 40
be readily attached by pushing the end which
carries the rivet 23 endwise against the rubber
sleeve I3 and toward the slot 24, with the fingers
and without the use of a tool, until the rivet 23
enters the slot.
When two rubber sleeves, such as used on the
'present spacer, with linings made of the same
'
’
thickness and quality of material, but without
The lined sleeves are composed of the rubber ‘ the projecting corners, are used on the present
sleeves I3 and I4 and tubular metallic linings 25 spacer, the rubber sleeves may be injuriously
which are adapted to slide snugly upon the cor- i distorted because there is not sufficient bearing
responding bar. The lining 25 is produced by
folding a strip of metal about .008 inch thick to
the form shown. This thin metal makes a flex
ible compressible lining for the rubber sleeves I3
and¿ I4. As shown best in Fig. 2, this lining is
somewhat shorter than the rubber sleeve in
which it is placed so as to leave a portion 26
of the rubber sleeve projecting beyond the me
(10 tallic lining at both ends thereof.
'
The normal width of the passage through the
rubber sleeves is somewhat less than the width
of the lining and must be stretched to vinsert
surface between the lining and rubber; but, when
linings having the form and bearing area con
templated in the present invention are used, the
hair is securely lheld without undue injury to
the rubber sleeve.y
-
One purpose of the liner is to increase the bear
ing surface against the rubber without increas
ing the thickness and therefore the weight of _
the bars. The liner also reinforces the bar, fa C0
cilitates the sliding on and off of the lined sleeves »
and greatly increases the resistance against the
tendency ofthe sleeve to turn when the hair is
the lining, but, as the rubber sleeves project be- ’ being stressed. .

An optional and equivalent construction that
ber sleeves contract in width somewhat as shown would permit the removal and replacement of
in Fig. 2.

,
This contraction obviates interference between
the ends of the sleeves at 26’ when the spacer
is closed. The projection of the rubber sleeve
at the open end of bar 6 prevents the connectq
ing and clamping link from falling olf bar 6 when
spacer is open.
As shown most clearly in Fig. 4, the gripping
faces of the sleeves I3 and I4 are the narrower
a lined sleeve from bar 6 would be produced byV
making a rigid connection between bar 1 and
hinge link 8 similar to the connection shown be
tween hinge link 8 and bar 6, a detachable con 70
nection between hinge link 8 and bar 6 similar
to the connection shown between bar 6 and link
I5 and a pivot connection between link I5 and
bar 6 similar to the connection shown between
bar 1 and hinge link 8. Obviously, a rigid con 75
2,136,196
nection may be eliminated by making the con
nected parts integral with one another.
All of the metal parts of this spacer are'made
of corrosion resisting material of great~ strength
and light weight, sucli, for example, as aluminum
and stainless steel.
The sleeves I3 and I4 may be made of any
ìsuitable elastic material, such, for example, as
a heat and chemical resisting rubber composi
tion.
From the above description, it is believed that
the construction and advantages of this device
will be readily apparent to those skilled in this
art. It is also believed to be evident-that var
in ious modifications may be made from the exact
details shown and described without departing
from the scope of the invention as it is deñned
in the claims.
