which a strand of hair to be waved is inserted,
and the pad is then pushed down close to the
scalp. Because of the character of the material
usually employed in such pads being relatively
.30 soft and ?exible, the slit becomes easily deformed,
particularly after the pad has been used a few
times, so that the edges of theslit remain sep-,
arated, producing an ‘opening of substantial size.
When such a pad'is used on a strand of hair
very often a substantial area of the scalp is ex
posed through the slit-opening, and, consequent
ly, said portion of the scalp is not protected
against the heat emitted from the heated device
applied to the curled strand of hair. It has also
4.0 been observed that in using such pads, the strand
of hair which is inserted through the slit may
become bunched at either end or central portion
of the slit, which may be due to the pad slipping
on the strand of hair or the manner in selecting
45 the hair constituting the strand to be curled, and
due to the character of material of the pad, the
slit remains open, thus exposing the immediately
adjacent portion of the scalp to the heat given off
by the heated devices.
S ‘ It is, therefore, one of the objects of this in
vention to provide an improved protective pad
for the above mentioned purpose which is con
structed to fully protect that portion of the scalp
immediately adjacent the heating device.
Another object is to provide an improved pro

ing of my invention, I have illustrated in the
accompanying drawing, a preferred embodiment
thereof, from an inspection of which when con
sidered in connection with the following descrip- ,
tion, my invention, its mode of construction, as
sembly and operation, and many of its advan
tages should be readily, understood and appreci
. ated.
Referring to the drawing in which the same
characters of reference are employed to indicate
corresponding or similar parts throughout the
several ?gures of the drawing:

The illustrated embodiment of my invention,
as depicted in the drawing,'is of laminated con
struction and includes two superimposed sheets
of material It, such as felt, or other suitable
material, which are of the same shape and are
secured together at their marginal edges by
stitching, as indicated at H. The laminated pad 55

the hair is wound into curl form preparatory to

‘
The edges of the slit I2 are yieldingly urged
toward each other by a pair of spring members
l4 and I5 interposed between the sheets ID. The
spring members are of substantially U-shaped
formation and are disposed in opposite relation,
tically no portion of the scalp is exposed through
the slit to the heat emitted by the heating device.
Manifestly my improved form of protective pad
may be used over and over again many times and
will not permit the slit to become deformed as in
pad constructions now employed.

It is believed that my invention, its mode of
construction and assembly, and many of its ad
vantages should be readily understood from the
one on top of the other, so that their respective

defined in the appended claim.

What I claim and desire to secure by Letters
Patent of the United States is:
A scalp protective element of the character
described comprising a pad composed of two
apart rows of stitching [8 which are disposed on
opposite sides of the slit l2 and which also con
nect both sheets of material together. Said rows
of stitching are located in close proximity and in
20 substantially parallel relation to the slit and ex
tend beyond both ends of said slit, as seen in
Fig. 2. Said rows of stitching l8 may be con
nected together at their corresponding ends, as
indicated at l9, to form a complete stitched clo
sure around the slit. If desired, only one spring
member may be employed and still obtain a rela
tively efficient and satisfactory construction.
It is to be understood that in the manufacture
of my improved protective pad construction, the
30 sheets [0 are ?rst secured together at their cen
tral portion by the rows of stitching l8 and I9,
then the spring members are placed in position,
and then the marginal edges of the sheets are
secured together by the stitching II.
By virtue of my improved construction, the
edges of the slit will frictionally engage the
strand of hair when it is inserted therein and
will thus hold itself in ?xed relation to the hair.
And, likewise, the strand of hair may be properly
distributed in the slit and will be ?rmly main
superimposed sheets of ?exible material secured
together, said pad having an elongated slit there
in through Which a strand of hair may be in
serted to permit disposing said pad in close prox~
imity to the scalp, said sheets of material being
connected together adjacent to and on opposite 30
sides of the slit by rows of stitching extending
in the same general direction of said slit, and a
pair of spring members of substantially U-shaped
formation disposed between said sheets of mate
rial in opposite relation to each other with their
leg portions disposed in straddling relation to
said rows of stitching for yieldingly urging the
edges of the slit toward each other.
