5 Claims.
This invention relates to new and useful im
provements in hair curling clamps.
In giving a woman a permanent, ‘croquigncle
or similar hair wave, the head of hair is theo
retically blocked off into squares, similar to a
checkerboard. The thatch or lock of hair con
stituting each theoretical square is tightly wound
upon a roller.
Before completing the winding,
the hair clamp is placed in position with its
clamping bars on each side of the thatch of hair,
and the winding is then completed by making the
?nal adjustments and securing the clamp or roller.
A more effective wave is produced by reducing
the size of the squares and increasing the num
ber of rollers and clamps. Thus it follows that a
less expensive wave may be produced by in
creasing the size of the squares and reducing
the number of rollers ‘and clamps required. How

bar on which it is mounted; the latching member
will readily engage the locking means through
out its length, whereby as the clamping bars are
swung together to accommodate the different
sizes of the squares of hair, said bars will remain 5
in any of the adjusted positions.
A construction designed to carry out the in
vention will be hereinafter described, together
with other features of the invention.
The invention will be more readily understood 10
from a reading of the following speci?cation and
by reference to the accompanying drawing, in
which an example of the invention is shown, and
Figure 1 is a view of a device constructed in 15

and partly in elevation, the roller being omitted

common use are limited to the quantity of hair
which may be clamped therein.

Another object of the invention is to provide clamping members or bars II and I2 encased in
?exible sleeves or jackets [3. It is pointed out
an improved hair curling clamp having the latch
ing means so arranged that when the clamping that this structure will cause the air to circulate
matically latch, whereby variations in the thick

the bottom of the clamp, the heat which is used

the clamping bars will be compensated.
A further object of the invention is to provide
45 an improved hair curling clamp which may be
easily and expeditiously latched in‘ position,
simply by exerting pressure on opposite sides of
the clamping rollers; and also whereby the thatch
of hair may be more tightly clamped because of
the latching arrangement.
A particular object of the invention is to pro
vide a hair curling clamp in which one of the
bars has a latching member mounted thereon
which is curved or arcuate so that throughout its
55 length it has the same radii as the end of the
cessive heat from reaching the scalp and in
juring the same.
The bar I! has a cross-head M at one end 45
directed at substantially right angles thereto.
A bracket I5 is bent upwardly from the outer
transverse edge of the head M. The other bar
[2 has one end pivoted to said head by a screw
it, Figure l, or any other suitable means. It 50
is obvious that said bar l2 may be swung away
from and toward the bar II to open and close
the clamp. When the clamp is completely closed,
(Figures 1, 3, 4 and 5,) the sleeves intimately
engage each other along their entire lengths, 55
whereby thatches or looks of hair may be clamped
wave or the like, the hair is theoretically blocked
A bracket H is ,bent upwardly from the outer
types of waves, usually the more expensive ones,
end of the bar l2 and at the opposite end of the
clamp to that of the bracket 15. This bracket
I1 is offset, Figures 3 and 4, whereby a notch IS
in its upper end is disposed relatively between the
The bracket I1 is provided on its outer
face with a segmental or arcuate rigid ?nger or
10 arm l9. This curved arm I9 extends substantially
in a radius, which has its center at B, and which
is also the pivot point of the bar I2. The inner
face of the bill is formed with a plurality of
closely spaced ?ne teeth 20, and will be seen in
15 Figure 8.
An outwardly extending upright hinged keeper
22 is provided with an outwardly extending
thumb piece 23 on one end and an inwardly ex
tending arm or ?nger 24. The ?nger extends
20 from the keeper longitudinally under the bar H.
The end of the bar ll adjacent the bracket I?
is formed with an upturned ear 2! (Figure 7),
having an opening 2!’ therethrough. A stud or
boss 25 formed on the keeper above the ?nger
25 24 loosely engages in the opening in the ear 2|,
whereby said keeper is hinged to the ear and
supported thereby.
A slot 26 is provided in the
keeper, so that the arm I9 may freely slide there
A laterally extending lug 21 is mounted on said
keeper adjacent the slot 26 and is provided with
off into squares, as a checkerboard.
In some
the squares are rather small. As each block or
square of hair is wound on a separate roller, the
squares are made larger for cheaper waves so
as not to consume so much time and. not use too
many rollers and heaters, as one heater is used
for each roller. Of course, the larger the square,
the greater the quantity of hair which must be
clamped. With the ordinary clamp it is impos
sible to close the same with an excessive thatch
of hair between its bars, therefore if the squares
are large all of the hair is not clamped and con
sequently not curled.
With applicant’s inven
sired and satisfactory results are obtained, be
cause the spring latch will compensate for the
varying thicknesses of thatches of hair from each
After the hair is blocked off into the desired
size and number of squares, the thatch or look
of hair from the ?rst selected square is partially
wound upon the roller 30, in the usual way. The
clamp is opened, as shown in dotted lines, at C 25
in Figure 1. The clamping members II and 12
are then passed on each side of the lock of hair
below the roller and latched. In order to latch
the members, it is merely necessary for the end
of the arm 19 to enter the slot 26 in the keeper 30
22, whereby its teeth 20 will engage the knife
a knife edge 21’ overhanging the slot for engag
ing the teeth 20 of the arm !9 (Figures 6 and 7).
The inner end of the ?nger 2d is connected with
35 one end of a spring 28 which is suitably secured
to the under-surface of the bar H, such as by
encircling a, screw or lug 29. Thus, it will be
seen (Figures 1 and 6) that the keeper 22 and
the knife edge 21' engage the arm l9 and teeth
40 20 so that the bars II will be held in any de
sired position, whereby said bars are adjustable
edge 21’ of the arm. The operator, by pressing
on opposite sides of the members, may force
them together, which causes the teeth to slip
to clamp around varying thicknesses of thatches
of hair. It is pointed out that the spring 28
acts to displace the ?nger 24 to one side into
45 engagement with the side of the bar ll, whereby
of the arm and thus the bars or members will
the lug 21 is tilted or canted to engage its knife
edge in the teeth 26 on the arm l9. After the
tion, the squares may be made as large as de
over the knife edge 21' as the arm 19 travels 35
through the keeper.
Owing to the spring hing
ing of the keeper, it is obvious that a ratchet ac
tion will be produced while the latch is being
moved to its latching position. When pressure
on the members H and I2 is released, the knife
edge 27' will prevent any retracting movement
be automatically latched in the position to which
they are swung.
It will be seen, from the foregoing, that owing
to the ?neness of the teeth 20, minute adjust
ments may be made and the operator merely

As is shown in Figure 2, a hair winding roller
30 is provided for rotatable mounting in brackets
55 and I7, and the usual hair keeper or tongue
3| is hinged thereon for con?ning the ends of the
55 strands of hair, previous to winding the hair on
said roller. At one end, the roller is provided
with a headed trunnion 32 for engaging in the
notch of the bracket ll; while on the opposite
end of said roller, a stub shaft or pin 33, hexag
60 onal in cross-section, is mounted for engage
ment in a transverse slot 34 which extends in
wardly from one side on the upper end of the
bracket 55. A knurled knob 35 is secured on
the outer end of the pin 33.
The upright bracket I5 is provided with an
outwardly directed ear 36 at its upper end, on
the side opposite to that in which the slot 34
opens. A latch hook 31 is pivoted to the ear 36
and is formed with a thumb piece 38 and a down
70 wardly extending bill 39. The latch may be
swung so that the bill 39 engages over the pin
33 when the same is in the slot 34 and secures it

In preparing the head of hair for waving so
75 as to produce what is known as a “Croquignole”
ing taking care of itself. The arm I9 is long 50
enough to provide latching for a wide variance in
thickness of the thatches of hair, therefore a
small quantity of hair may be clamped as effec
tively as a large amount. After the clamp is
latched, the rolling and curling is carried on in 55
the usual manner.
When it is desired to release the clamp, it is
merely necessary to grasp the thumb piece and
swing it to the position shown in dotted lines
in Figure 6. This will withdraw the knife edge 60
21' from the teeth 2!! permitting the members of
the clamp to swing apart and allowing the op
erator to open the clamp in the usual manner.
What I claim and desire to secure by Letters
Patent, is:
1. A hair curling clamp including, a pair of
hair clamping bars, an elongate latch member
extending from one end of one of the bars, teeth
on one side of the member, a keeper on the other
