PERMANENT WAVE CURLER
Sidney Alexander Hamilton, Shreveport, La.
Application May 9, 1936, Serial No. 78,926
1 Claim.
(01. 132-34)
This invention relates to curlers for use in
permanent Waving the hair.
,
Heretofore it has been the practice to use spin
dle-like structures having relatively rotatable
5 parts and after the hair has been wrapped there
around and fastened to the respective parts of
the curler, one of the parts of the curler has been
rotated relative to the. other to tighten the
wrapped hair on the curler and hold it until the
10 hair has been heated and steamed sufficiently
to retain the' curl.
In tightening the wrapped
- hair, however, some of the whorls have been
pulled more tightly than others due to the fric
tional contact of the hair with the surface of
15 the elongated spindle on which the whorls are
formed. Consequently the whorls of hair at one
end of the curler have been drawn tighter than
those at the other end. This has all resulted
in unsatisfactory work in the lack of perma
nency and uniformity of the finished waves and
20
curls.
An object of the present invention is to elimi
nate the uneven distribution of tension on the
coiled hair by providing the spindle portion of
IO 01
the curler with anti-friction devices so that the
wrapped hair on the spindle will not drag on
the spindle when subjected to tension by a twist
ing action of the rotatable parts of the curler but
will move longitudinally of its stands without ob
jectionable frictional resistance, thereby insur
ing uniform stretching of all of the 'convolutions
of the wrapped hair.
With the foregoing and other objects in view
which will appear as the description proceeds,
the invention consists of certain novel details of
construction and combinations of parts herein
after more fully described and pointed out in the
claim, it being understood that changes may
be made in the construction and arrangement
of parts without departing from the spirit of the
invention as claimed.
In the accompanying drawing the preferred
form of the invention has been shown.
In said drawing:
Figure 1 is an elevation of the curler with hair
wrapped therearound and held tightly.
Figure 2 is a central longitudinal section, a
portion being broken away. .
Figure 3 is a perspective View of one of the
anti-friction members. 7
Figure 4 is an elevation of the complete curler.
Referring to the ?gures by characters of refer
ence, I designates the handle of the curler with
a concentric recess 2 in one end.
A rod 4 is
55 anchored at one end in handle I while its other
end is anchored in a head 5 preferably tapered
toward its free or outer end which is slotted lon
gitudinally as shown at 6.
V
The recessed end 2 of handle i is rotatably
mounted on one end of an elongated spindle
section 7 and the rod ii is also rotatable in said
section. One end of the spindle section is made
smaller and a spring 9 is anchored at one end
and wrapped therearound, the several convolu
tions of the spring being normally expanded 10
against the wall of recess 2 so as to serve as a
spring clutch which allows the section ‘i to rotate
in one direction independently of handle I but
holds it against retrograde movement relative to
15
the handle I.
Mounted on rod d between section 1 and head
5 is a series of alined cylindrical spindle sec
tions it all rotatably mounted independently of
each other and abutting at their ends. The
end sections H can be tapered down to the
diameter of the section I and head 5 respectively.
The outer faces of the sections 1, IE] and I!
are flush and cooperate to form a spindle hav
ing a smooth outer surface formed of relatively
rotatable portions and the outer surface of sec
tion I can be tapered or otherwise shaped so as
to be easily gripped between the ?ngers of one
hand while handle I is being held by the other
hand.
In practice that portion of a lock or wisp of
hair I-I nearest the scalp is tied to head 5 by a
cord placedin slot 6 as shown at a. The hair
is then wrapped about the curler and tied by
another cord to the section ‘I as shown at b.
The operator grasps section ‘I and the tied hair
thereon in one hand and turns it in one direc
tion while handle I is being held in the other
hand. Head 5 thus is held against rotation while
the section 1, which can rotate only in one di
rection because of spring clutch 9, will pull the, 40
hair about the sectional spindle and uniformly
tightenand stretch the convolutions. During
this operation the hair will cause independent
rotation of the sections ill and H so that fric
tion will be eliminated and all of the convolutions
of hair tightened and stretched equally. As the
clutch prevents retrograde movement of the sec
tion ‘I, the hair will be held tightly after the
twisting or curling operation until it is desired to
release it whereupon the cords a and b are re 50
moved and the curler can be withdrawn.
What is claimed is:
A curler including a handle, a head, a rod
connecting the handle and head, an elongated
spindle section mounted for rotation on the rod 55
2
2,108,374
and projecting into and rotatable within the
handle, said section having one end tapered to
provide a ?nger grip, means within said section
for holding it against rotation in one direction
relative to the handle, additional shorter spin
dle sections mounted for rotation on the rod be
tween the head and the elongated spindle sec‘
tion, all of the sections abutting and being rotat
able independently, said shorter sections coop~
erating to provide a spindle portion tapered at
one end toward the elongated section and at its
other end toward the head thereby to provide a 5
bulge.
