PROTECTOR BAD FOR PERMANENT HAIR WAVING Filed April 1.7, 1936 f5 M129 fiomi Patented F eb. 15, 1938 UNITED STATES PATENT oFFicE o o 2,108,469 I rnorizo'ron; ran FOR PERMANENT Ham. .{WAVING v Harry Bon'at, New York, X. e 7 Application April 17, 1936, Serial at. yams lClaim. roi szeab r v flhis invention relates to scalpprotecting- .t eme pad wher'ein the edges of the slit are means for use with hair waving apparatus of the type known in the art as permanent hair waving apparatus. Such apparatus generally includes a plurality of, electrically heated devices adapted to be applied to curled strands of hair, and which 'are usually permitted to remain in place thereon for a substantial period of 'time'for baking the hair to impart a'substantially'p'en' manent wave thereto. Because such devices are usually located in close proximity to the scalp in order to obtain a wave in the hair which commences as close to the scalpas possible, it is necessary to provide some means for each of such devices for insulating and protecting the immediately, adjacent portion of the scalp from heat emitted by such devicesso asfto relieve discomfort caused thereby. This protecting means also serves to guard against possible burn or other injury which may result by direct contact of the heated devices with the scalp.

The protective means Which has been heretofore extensively employed in this art is in the form of a pad of sheet material, such as felt, which is provided with an elongated slit through 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 soft and flexible, the slit becomes easily deformed, particularly after the pad has been used a few times, so that the edges of theslit remain separated, 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 exposed through the slit-opening, and, consequently, 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 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 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.

It is, therefore, one of the objects of this invention to provide an improved protective pad for the above mentioned purpose which is constructed to fully protect that portion of the scalp immediately adjacent the heating device.

Another object is to provide an improved proyieldingly urged toward each other. 1 A further. object resides in the provision of an improved protective element of the above mentioned type which frictionally engages the strand of hairinserted in the slit for maintaining the hair and'the pad'in a relatively fixed position of adjustment with respect to each other.

A still. further objectof this invention is to provide an improved protective pad element of laminated sheetsof material with spring means interposed therebetween for yieldingly urging the edges of the slit towards each other.

With the foregoing and other objects in View which will appear as the description proceeds,ithe invention consists in. certain 'novel features of construction, arrangement and combination. of

parts hereinafter "fully described, illustrated in the-i accompanyingv drawing, and particularly pointed out inthei appended .claim, it being un-' derstood that Various changes in the form, proportion, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

For the purpose of facilitating an understanding of my invention, I have illustrated in the accompanying drawing, a preferred embodiment thereof, from an inspection of which when considered in connection with the following description, my invention, its mode of construction, assembly and operation, and many of its advantages should be readily, understood and appreciated.

Referring to the drawing in which the same characters of reference are employed to indicate corresponding or similar parts throughout the several figures of the drawing:

Figure l is a perspective view of a scalp protective element embodying the present invention;

Fig. 2 is a sectional view of the protective element with one layer of sheet material removed and showing the arrangement of spring means for yieldingly urging the edges of the slit toward each other;

Fig. 3 is a transverse section through the protective element, taken as indicated at line 33 on Fig. 2.

The illustrated embodiment of my invention, as depicted in the drawing,'is of laminated construction 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 is provided with an elongated slit l2, through which a strand of hair may be inserted, and the pad then pushed down in close contact with the scalp, after which the strand of hair may be wound in curl form and an electrically heated device applied thereto for baking the curled hair to form a permanent wave therein, as is well understood in the art.

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, one on top of the other, so that their respective leg portions I6 and I 1 straddle the two spaced apart rows of stitching [8 which are disposed on opposite sides of the slit l2 and which also connect both sheets of material together. Said rows of stitching are located in close proximity and in substantially parallel relation to the slit and extend beyond both ends of said slit, as seen in Fig. 2. Said rows of stitching l8 may be connected together at their corresponding ends, as indicated at l9, to form a complete stitched closure around the slit. If desired, only one spring member may be employed and still obtain a relatively efficient and satisfactory construction.

It is to be understood that in the manufacture of my improved protective pad construction, the sheets [0 are first secured together at their central 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 fixed relation to the hair. And, likewise, the strand of hair may be properly distributed in the slit and will be firmly maintained in such position during the period that the hair is wound into curl form preparatory to applying the heating device, while at the same time the slit is substantially closed, so that practically 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 advantages should be readily understood from the foregoing without further description, and it should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation Within the purview of my invention as 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 superimposed sheets of flexible material secured together, said pad having an elongated slit therein through Which a strand of hair may be inserted to permit disposing said pad in close proximity to the scalp, said sheets of material being connected together adjacent to and on opposite 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 material 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.
