5 Claims.
This invention relates to the permanent Waving» and similar treatment of hair and particularly to the practice of applying sachets or treating pads to hair tresses wound and stretched upon
curling rods carried by hair clamps preparatory
to the application of heat.
In the conventional practice the tress is ?rmly
clamped near the scalp and after winding the
tress upon the curler and vmounting the curler
10 with the tress wound thereabout upon the clamp,
the sachet or other treating pad is applied upon
and over the wound tress and the ends of the
pad pinched about the sides of the wind for the
treating operation. Irrespective of the care exercised in positioning and applying the sachet,
the under side of the wound tress, namely, that
portion adjacent the clamp, is either imperfectly
contacted or not contacted at all by the treating pad and an imperfect closure of the win-d is
obtained with the result that the wound tress is
non-uniformly treated and leakage of the hot
fluid and vapors often occurs with injury to the
scalp. Moreover, when external heaters are employed the latter sometimes burn the exposed or
imperfectly shielded tress.
One of the objects of the invention is the eirective closure, protecting and treating of the wound
hair tresses, whereby the whole circumference
of the wound tress is intimately contacted by the
treating pad with resultant uniform treating and
waving of the tress.
A further object is to effect a, Substantially
complete enclosure of the wound hair tress within
the sachet or treating pad, notwithstanding the
mounting of the curlers upon the suppgrting
clamps, whereby the whole circumference of the
wound tress is uniformly treated and leakage in
the neighborhood of the unwound part of the
tress near the roots avoided,
A further object of the invention is ‘a novel
sachet or treating pad for use in hair waving.
Further objects of the invention will hereinafter appear.

the Clamp l, the Satchet 01‘ treating pad 4 eXtendS
between the clamp l and the curler carrying the
wound tress B, leaving no part Of the Wind ex
posed and thereby forming a double seal or pro- 40
tection against the hot vapors and ?uid reaching
the scalp- MOI‘BQVBI‘, the sachet Completely eh
circles and encloses the Whole circumference of
the wound tress of hair which ensures a thorough
and uniform treatment of the Wound tress.
Figs. 3 t0 6- When a protecting Dad 5 Sepa
rate from the clamp is utilized it is ?rst threaded
upon the tress 13, this Pad usually having a Slit
or opening in it for the reception of the tress.
The clamp I is then caused to grip the tress at a 50
point adjacent the pad 5.
The sachet or treat
ing pad 4 is provided with a transverse slit 4’
intermediate its ends and edges, as indicated, for
the reception of the tress in a closely ?tting man
ner. The sachet is threaded over the tress and '55
2,1 16,079
brought down upon the clamp l with the tress
passing through the slit 4'. Fig. 4 illustrates a
convenient way of threading the tress through
the slit 4', when the slit is closed at both ends
and stops short of both sides of the pad as illus
trated, a hook 6 being employed in this operation.
The tress is then wound from the tip towards
the roots (Fig. 5) upon the curler 2 to form a
substantially cylindrical wind, whereupon the
10 curler 2 is then inserted upon the holders 3 of
the clamp l. The wind is then tensioned and
stretched by applying a key or wrench to the
spindle of the curler and turning it in the con
ventional manner. The sachet is then brought
from both sides about the wound tress
of hair and the ends are caused to overlap as
indicated at In and II. The wound tress thus
formed and totally enclosed in the sachet 4 is
then ready for the application or production of
20 heat utilized in the treatment of the hair
It is thus apparent that the whole circumfer
ence of the wound tress is brought into efficient
hair treating relation with the sachet 4, the lat
ter entirely enclosing the wound tress. A uni
25 form and thorough treatment of the hair tress is
thereby effected. Moreover, the wound tress,
being entirely enclosed within the sachet itself,
is thoroughly shielded against and protected from
any other part of the appliance, such as a con
30 ventional heater clamped thereto. The internal
heat is maintained and preserved more efliciently
and the vapors and liquids cannot escape and
drip upon or burn the scalp. The slit or ori?ce
4’ is so dimensioned as to afford passage ex
35 actly to the tress of hair and is effectively sealed
by the tress of hair passing therethrough thus
preventing the escape of vapors or ?uid along the
unwound root part of the tress. For more effec
tively forming the seal at the slit the latter may
be reinforced as, for example, by absorbent elas
tic material so that on the tress of hair being
drawn through the slit the material adjacent
the slit may be pressed down for the purpose of
tightly clamping the hair tress at the position at
45 which it extends through the sachet. Thus the
body of the sachet 4 rests against the underneath
side of the wound tress and directly in contact
with the clamp protector or support or in con
tact with another protecting layer which rests
50 upon the clamp. The sachet is wrapped around
the curler and tress of hair from the bottom'
and away from the scalp contrary to the conven
tional practice of wrapping the sachet from the
top of the wind and only partially encircling the
55 wind.
In the preferred practice of the invention the
sachet is inserted with the tress passing through
the slit 4', as the next step immediately follow
ing the clamping of the tress by the clamp I and,
60 as indicated above, the tress may be passed
through the slit 4' by the use of a suitable instru
ment or hook 6. In the particular embodiment
illustrated, the sachet or pad is adapted to the
accommodation of a single tress of hair, but,
65 obviously, if more than one tress of hair is to be
treated by the use of the same pad the latter
should have for best results a slit for each tress.
The sachet 4 may otherwise be of any conven
tional character. For example, it may comprise
70 an outer envelope 12 of thin metal foil, piece of
tinsel or a sheet of material that is a good
conductor of heat, an absorbent lining l3 of soft,
thick flannel or cotton or otherwise spongy,
?brous or napped material, and ?nally an inner
shield M of parchment paper or equivalent sheet
material which is perforated or provided with a
multiplicity of small pin point holes l5. These
parts may be fastened together by seams Hi to
form a unitary structure. The absorbent lining
l3 serves the usual purpose in hair waving, name
ly,—it may be impregnated or soaked in advance
or at the moment of operation upon the hair
by a liquid or a paste or any other substance
which will facilitate that operation. It may be
dipped in the vaporizable solution for use in 10
the hair waving operation.
This solution does
not come into direct contact with the tress of
hair B, wound around the curler since the per
forated layer I4 retains the liquid which permits
the vapors from the liquid to pass through the 15
numerous small openings, thereby forming jets of
vapor which penetrate the tress of hair for treat
ment. The tress of hair is usually moistened in
advance by any suitable material which together
with the vapors passing through the perforations 20
from the absorbent layer results in the proper
treatment of the hair. The paper shield [4 may,
if it be necessary, be extended to form an insert
between the soft thick piece [3 and outer_ en
velope I2 of the sachet 4 and this part of the 26
paper need not be perforated.
Where an external heater is clamped around
the curler and the wound tress for applying heat
externally, as for example as shown in Fig. '7, the
sachet is preferably provided underneath with 30
skirts or ?ange pieces I9, 20 disposed on the
opposite sides of the slit for the purpose of shield
ing the unwound part 2| of the tress extending
between the slit and the clamp from the heat of
the heating elements. These protecting skirts l9, 35
20 project between the heater jaws 22 on the one
hand and the tress 2i and clamp on the other
hand and thus prevent the heater jaws from
touching the tress of hair at the point where
it comes through the slit 4' or effectively insu 40
late the jaws.
These protecting skirts or ?ange pieces of the
sachet may be formed in any suitable manner,
as by folds of its envelope I2 alone, or by folds
of this envelope and the absorbent lining I3 and 45
of its shield 14, as shown. The two superposed
folds l9 and '20 form two double lips, triple
lips, or quadruple lips, more or less opened out,
which are disposed between the hair and the jaws
22 of the heater. Preferably, the protecting skirts 50
form an integral part of the envelope l2, the ab
sorbent lining l3, and the paper shield M. The
whole may be made as shown in Fig. 8 in such
wise as to form an X structure with a central
slit 4’ for the passage of the lock of hair. Two 55
groups or separate parts 23 and 24 are secured
together face to face along the line 25, as by clips
26 to leave a slit 4’ for the passage of the hair
tress and the shorter parts or edges l9, 2!] form
the protecting skirts.
The two ends of the envelope 12 of the wrapper
or sachet may be of different areas, in order that
the one of them may be pulled down to the neigh
borhood of the base of the other for the purpose of
enclosing the wrapper that is pressed down by 65
the jaws 22 of the heater. It is this form of con
struction of the sachet which Figure 6 shows
While a heater having the jaws 22 is shown for
applying heat externally to the sachet, it is under 70
stood that the invention is not limited to this
method of heating, as any conventional method of
developing or applying heat in the hair waving
art may be employed. Likewise, the invention is
not limited to the particular type of curler or 76
clamp as any conventional appliance may be used
which includes means; for tensioning the coiled
tress and locking the curler on the clamp against
uncoiling. The sachet may be varied in construc
tion, according to conventional practice within
the limitations described above.
I claim:
1. A sachet pad for use with a ?at clamp in
treating and waving hair in the croquignole proc
10 ess comprising two separate, identically con
structed parts fastened together face to face
along a line adjacent one edge with the fastening
means discontinued through a part of the width
to form a slit for the reception of a tress of hair,
15 the short projecting ends forming protecting
skirts to overlie the clamp and underlie the jaws
of a croquignole heater when placed about the
wound tress.
2. A sachet pad of the character set forth in
20 claim 1 which comprises an inner absorbent pad
disposed between an outer metallic foil and an
inner ?nely perforated parchment paper with the
metallic foil projecting at one end beyond the
absorbent pad for forming a closed tube about
25 a cylindrical wind.
3. A sachet pad for treating and waving hair
in the croquignole process having absorbent ma- 7
terial disposed between a metallized paper and
a perforated paper shield, with a double fold
formed therein and with the double fold forming
two lips with a slit in the center line of junction,
the ends of the sachet pad situated to either side
of the slit being adapted to be folded about a
cylindrical wind in overlapping fashion, the
double fold forming skirts which insulate the jaws
of the heaters from the hair and head.
4. A sachet pad for use in the croquignole proc
ess having a transverse slit formed intermediate
the ends thereof for accommodating the insertion
of a sachet pad about a flat band of hair and
having protecting skirts ?rmly attached to it,
said skirts extending from either side of the cen
ter line of the slit through which the flat band
of hair passes, and being adapted to be disposed
between the heater elements and that portion of a
tress of hair between the clamp and the wind.
5. A sachet pad for treating and waving hair
having a transverse slit formed intermediate the 20
ends thereof to accommodate‘ the passage of a
lock of hair therethrough prior to the hair being
coiled on the curler, whereby said pad may be
rolled up over itself after the wind is formed
about the curler and in such manner as to form a 2
complete protective and treating tube thereabout.
