1 Claim.
This invention relates to a hair waving device,
and particularly to a mechanism for, holding and
releasing the tension on the spool or shaft on
which the hair to be curled is wound.
‘ 5
An object of the invention is to provide a hair
curling device wherein the hairis wound on a
spool or shaft and thereby placed under tension,
said spool or shaft having a mechanism therein
for preventing the spool or shaft from rotating
lo and thereby allowing the hair to unwind, means
being provided to release the mechanism, and to
thereby release the tension "on the wound hair,
whereby the hair curling device may be quickly
and easily removed.
Other objects and advantages are to provide a
release and holder for hair curlers that will be
superior in point of simplicity, inexp‘ensiveness of
construction, positiveness of operation, and facil
ity and convenience in use and general ef?ciency.

the invention is illustrated in the form considered
to be the best, but it is to be understood that the

The base
_ members I and 2 are attached to the under side
of the plate 8, the member 2 at one end thereof
being pivotally connected to the plate 8, whereby
the member 2 may be swung apart from the mem
ber I. At the other end of the plate 8 on the
) member I, I have provided a form of a clamp for
locking the base member 2 in parallelism with
the member I', said clamp consisting of a bar 5
pivoted at 6 to one side of the. plate 2, the other
end of said bar having a cam ‘I thereon adapted
(5,5 to be frictionally engaged with the side of the
holders I and 2 may be wound upon the spool or
mandrel I I. In winding the hair on the spool or
mandrel, the same is removed from the holder
and the extreme ends of the hair are held on the
spool in some conventional manner, and the op
erator rotates the spool with the hair con?ned
thereon toward the scalp until the entire strand
has been wound thereon. As the spool, with the 50
hair thereon, reaches the holder the operator
places the same into the slots Ill on the opposite
standards 9, and thereafter continues to rotate
the spool by movement applied thereto, through
the head I5 on the shaft I2, until such time as 55
the wound hair has been placed under the de
sired degree of tension. It will be noted that the
spool ll rotates about the bearings on the oppo
site ends thereof in the slots ID in the standards
9. The engagement of the ratchet I3 and pawl
l4 permits the spool to be rotated in one direc
tion to wind the hair on the spool but the spool
may not move in the opposite direction until the
ratchet thereon is released from engagement with
the pawl. When the hair is tightly wound on
the spool, it exerts a force directly upon the spool,
which tends to pull the ratchet on the spool di—
rectly into contact with the pawl and as a result
the spool is held immovable in the standards.
The ratchet on the spool in relation to the pawl
14, is that of a one-way clutch.
Upon completion of the hair waving operation,
or if for any other reason it should be desired to
release the hair wound on the spool, the operator
merely pressed outwardly on the spool to declutch
or disconnect the ratchet I3 from the pawl, which
action tends to force the spool outwardly a slight
distance in the enlarged portion N5 of the slot [0,
whereby the tension on the wound hair is im
mediately released, and the spool may be removed
from the standards.
I have found that by embodying a release
mechanism of the kind heretofore described, in a
hair curler, that it is possible to release the curlers
from the hair with absolutely no discorn?ture to
the patient. The usual type of hair curler is not
provided with any means for releasing the ten
sion on the hair curler, other than by opening
up the members which clamp the hair adjacent
the scalp, and then manipulating the holder into
an inverted position so that the spool may be
discharged or released therefrom. This pro
cedure usually causes the patient a great deal of
discomfort, and where the head is blocked out
with a number of hair holders and curlers
throughout the entire area thereof, it is exceed
ingly di?icult to release the hair from the curlers.
With my release mechanism, tension on the hair
can be released quickly and easily, and the hair
curling apparatus can be removed from the head
without hurting the patient in the slighest degree.
Having thus described this invention, what I
claim and desire to secure by Letters Patent is:
A holder and release for hair curlers compris
ing a base; end members at opposite ends of said
base and projecting out from the face thereof,
each end member having an open ended slot
therein, one side wall of said slot being cut away
to form a curved recess; a spool on which hair
to be curled is wound, said spool having journals 2.0
at opposite ends thereof, one of said journals be
ing toothed and each of said journals being
adapted at times to rest within the recess in the
edges of said end members; and a ?xed detent on
one of said end members extending into the re 25
cess of said end member whereby said detent will
engage the ratchet on the spool when the spool
has hair wound thereon under tension, the ten
sion of the wound hair on the spool causing the
journals on said spool to be held in the recess in 30
the end members and by engagement of the
ratchet with the detent to hold the hair wound on
the spool and to resist unwinding of the hair
from the spool.
