HAIR CURLER
Joseph Jacobs, Bridgeport, Conn., assigner to The
A. J. Donahue Corporation, Milford, Conn., a
corporation of Connecticut
Application May 26, 1937, Serial No. 144,816
3 Claims. (Cl. 132-41)
This invention relates to improvements in hair
waving appliancesand has particular reference
to a curler of the type in which a strand of hair
is wound on the curler and secured in position
thereon until the curl has set.
Hair curlers of this nature have heretofore
been made in which two cooperating members are
pivotally connected for clamping the end of a
strand of hair therebetween, after which the
410 strand is wound about said members to form a
curl. When removing‘the curl from the mem
bers, diil‘lculty has been experienced in disengag
ing the Wound strand in its original state because
of the fact that the end of the strand is clamped
between the members of the curler, with the re
mainder of said strand more or less tightly wound
around said members, `so that the latter cannot
be readily separated by the pivotal movement
therebetween to relieve the clamping action of
,20 the members upon the strand.
As a conse
quence, a considerable pressure or pull must be
exerted upon the‘curler and strand in opposite
directions in order to disengage the curl.
In accordance with the present invention it is
25 proposed to facilitate the removal of a curl of
hair from the curler by so connecting and mount
ing the two cooperating members of the device
which hold the curl thereon that one of them
may be moved longitudinally of the other, pre~
paratory to the removal of the curl, to Withdraw
the movable member from clamping engagement
with the hair and thereby permit of easy removal
of the curl without undue distortion thereof.
-A feature of the invention is the provision of
an improved curler of simple and practical con
struction which may be manufactured at a min
imum cost.
v
The inventive idea involved is capable of re
ceiving a variety of mechanical expressions one
40 of which, for purposes of illustration, is shown in
the accompanying drawing wherein:
Figure 1 is a side elevation of the improved
curler constructed in accordance with the present
r invention.
Figure 2 is an enlarged top plan view showing
in its inoperative position the longitudinally ad
justable member of the curler which is utilized
to clamp the end of the strand of hair and about
50 which the strand is wound to form the curl.
Figure 3 is a longitudinal section through the
curler in its operative position.
Figure 4 is a section on the line 4_4 of Figure
3, and
55.
Figure 5 is a section on the line 5-5 of Figure
3, showing a strand of hair wound about the co
operating members of the curler.
In its preferred form, the curler is shown as
comprising a mandrel 5 made of a light material
such as aluminum. This mandrel is formed from `« Ul
a single sheet of the material bent into tubular
shape and slightly tapered, with both ends open.
Adjacent one end of the mandrel, as at l, the
same is reduced or cut away to form opposed ears
8 and the adjacent extremity of the mandrel ter (ifi)
minates in a finger grip 9. The other end of the
mandrel is provided with opposed `notches IIJ, the
purpose oi which will appear in the course of the
description.
`
A support, generally indicated by the numeral
iI, is pivotally connected to the ears‘ß of the
mandrel and has slidably mounted therein the
clamping member I2. This member extends lon
gitudinally of the mandrel for substantially its
entire length and conforms to the circumfer i210
ential contours thereof so as to cooperate there
with in securing the end of -a strand of hair be
tween the same preparatory to winding said
strand about the mandrel and clamp to form a
curl. The support II is of arcuate form in cross 25
section and has the side portions I3 disposed ad
jacent the ears 8 for pivotal connection therewith
and, at I 4, the support is cut to` form intermediate
and end guiding and supporting portions I5 and
i6, respectively. The portion I5 has a smaller 30
radius than the end portions I5, as will be best
seen from Figure 4 and in this manner there is
formed a guide channel I -I in which the clamp
I2 is movable, with the portion I5 engaging the
inner surface of the clamp and the portions I6 35
extending over the exterior surface thereof. The
end of the clamp I2 adjacent the support II is
widened and flattened to provide a linger grip I8
which cooperates with the grip 9 in the handling
of the curler and said grip I8 also forms a stop 40
adapted to engage the outer end of the support
II to limit the sliding movement of the clamp I2
to its operative position shown in Figures 1 and 3.
Adjacent the other end of the clamp, small studs
I9 project from the surface thereof and act as 45
stops engageable with the inner portion I6 of the
support II, as in Figure 2, to limit the sliding
movement of the clamp to its inoperative posi
tion, as when releasing a curl from the device.
The mandrel 6 and support II are pivotally 50
connected by the intermediate portion 20 of a
curl-retaining member 2| which is formed from
a single length of wire` Said portion 20 extends
transversely through the ears 8 and side portions
I3 and has coiled thereabout a spring 22 the ends 55
2,.
. 2,130,685
of which bear against the interior surfaces of
the mandrel and portion I5 so as to exert a
yielding pressure on said parts sumcient to main
tain the clamp in engagement With the main por
tion of the mandrel.- From the portion 20, the
sides of the retaining member 2l extend along
opposite sides of the mandrel 6 to the outer end
thereof. Here, the extremities of the Wire of
said member 2| are bent or looped together to
10 provide the detent 23 which is engageable in the
notches I0 of the mandrel to frictionally main
tain the member in its operative position in which
it extends on opposite sides of a curl 25 (Fig. 5)
to retain the latter in its wound condition on the
15
mandrel and clamp.
ì
In practice, to Wind a strand of hair upon the`
curler, the retaining member 2| is ñrst disen~
gaged from the outer end of the mandrel and
swung so as to extend in an opposite direction in>
20 which position it may be held in the hand and
employed to turn the curler when Winding the
hair thereon. The mandrel and clamp are then
separated by pressure upon the grips 9 and I3
and consequent pivotal movement between the
25 mandrel and support H against the tension of
the spring 22. The end of a strand of hair is
then inserted between the mandrel and clamp
after which the grips 9 and I8 are released so
Vthat the clamp will return toward its normal
30 operative position to secure the end of the strand
in place. The curler is then turned to Wind the
hair thereon and when this Winding operation
is completed the retaining member 2| is swung
back to its operative position with the sides there
35 of extending along the exterior of the curl and
the detent 23 engaged in the notches Ill. 'I‘he
device is then allowed to remain in this position
until the curl is set. Preparatory to removing
the curl, the retaining member may be ñrst clis
40 engaged from the notches Il) and the clamping
member l2 then Withdrawn longitudinally to the
position of Figure 2 in which it will be disengaged
from the curl to the extent that the latter may
be easily removed from the mandrel Without un
due distortion. It will be noted that the adjust
ment of the clamping member to its inoperative
position, reduces the effective diameter of the
curler to a suñicient extent to loosen the curl on
the mandrel whereby its Withdrawal is further
facilitated.
What is claimed is:
1. In a hair curler, a mandrel, an arcuate sup
port pivotally connected to said mandrel and in 10
cluding intermediate and end portions of different
radii which combine to form a guide channel, a
clamp slidably mounted in said channel to opera
tive and inoperative positions relative to said
mandrel,V and means to releasably retain a Wound 15
strand of hair on said mandrel.
2. In a hair curler, a mandrel, an arcuate sup
port pivo-tally connected to said mandrel and in
cluding intermediate and end portions of dif
ferent radii which combine to form a guide chan 20
nel, a clamp slidably mounted in said channel
to operative and inoperative positions relative to
said mandrel, said clamp having means at oppo
site ends for engagement with certain portions
of said support to limit the sliding movements 25
of said clamp, and means to r‘eleasably retain a
Wound strand of hair on said mandrel.
3. In a hair curler, a mandrel, an arcuate sup
port pivotally connected to said mandrel and in
cluding intermediate and end portions of dif 30
ferent radii which combine to form a guide chan
nel, a clamp slidably mounted in said channel
to operative and inoperative positions relative
to said mandrel, said clamp having means at
opposite ends for engagement with certain por 35
tions oi said support to limit the sliding move
ments of said clamp, and a curl retaining mem
ber formed from a single length of Wire having
an intermediate portion extending through said
mandrel and support to provide a pivotal con 40
nection between said elements.
