Patented Nov. 12, 1929 UNITED STATES PATENT OFFICE JAMES CHESTER BROWN, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO E. FREDERICS, INC., F NEW YORK, N. Y., A CORPORATION OF NEW 'YORK PAD Application tiled tranuary 19, 1928. Serial No. 247,817.

This invention relates to a pad of improved construction, and specifically aims to provide a device of this character primarily intended for use in connection with the permanent waving of hair.

'A It is an object of the invention to furnish such a pad which will embody few parts and may be economically and readily constructed by relatively unskilled labor and which may be employed with facility in the .process of permanent waving. A

A further object is that of constructing an article of this type which will be of such a nature that it maybe employed in but a single operation. As a consequence, the pad may be furnished by the manufacturer to the operator in sterile condition and, when once employed by him, will be discarded so that all objections which have arisen in connection with the repeated using of articles of this nature'are avoided, aside from the fact that by this expedient a pad in proper condition will always be presented at the initial stage of the operations, thus assuring most desirable results.

An additional object is that of furnishing a device of this character which' will have maximum qualities of absorption so that adequate treament of the hair may be effected 30 during the permanent waving operation.

With these and further objects in mind, reference is had to the attached drawings in which are illustrated practical embodiments of the invention and in which:

Figure 1 is a face view of a pad;

Fig. 2 is a partly sectional view showing the pad in use;

F ig. 3 is a view corresponding to Fig. l and showing a slightly different form of pad; and

Fig. 4 is a perspective and slightly exagerated view of pad portions as constructed 1n Fig. 3.

.By means of the present invention, it is intended that a sanitary pad be provided which, in certain aspects, will be self-destructive. In other words, the material of the pad will be atl'ected detrimentally by the conditions of moisture and temperature to which it is subjected during treatment so as to 60 render it unsuitable for further use.

Additionally, a pad of the present invention is to be constructed economically, and preferably to embody highly absorbent qualities, so that it may retain to a maximum extent Huid which enters into the treatment. Specifically, it is intended to employ pulp paper which may be arranged in the form of one or more layers. This material, being of a highly digested nature, will embody, to a maximum extent, qualities fluid absorption. Furthermore, such material lends itself, in manufacture, to having incorporated in its body a suitable chemical or chemicals, which subsequently may be liberated or become active upon the material being moistened to a proper extent. Finally, a material of this nature is preferred in that, if the pad has been previously used, this will become immediately apparent. It is to be understood, however, in the latter connection, that any material might be employed which, under the action of heat and/or moisture, becomes fragile or distorted to a sufiicient extent to render it unfit for further use.

Thus, as in Figures l and 2, a heat-conducting layer is indicated at 5. Specifically, this layer may be formed of a foil, such as aluminum, and arranged adjacent thereto may be a sheet of backing paper 6, it being understood, however, that this layer may be dispensed with. Disposed beyond the foillayer is a sheet 7 of, for example, parchment paper or other material which is substantially imperforate and moisture proof, it being here noted that this sheet extends beyond the edges of the sheet 5 so as to provide a closable sealing portion hereinafter referred to.

In turn, disposed in advance of the sheet 7 are one or more layers of pad material as indicated at 8, these layers being, for example, pulp paper, it being understood that in manufacturing the same, any desired thickness of material is provided and that such material may incorporate chemicals, as by impregnation, if desired, which, upon becoming active as, for example, by the use of moisture, are suitable for the treatment. The several sheets or layers 5 to 8 are secured to each other in any convenient manner, it being preferred, according to the present invention, to employ staples 9 for this purpose which, when the pad is in use, will preferably be so disposed that they will not transmit heat directly to the hair, resulting in its possible injury.

In using a pad of this nature the hair is washed and/or treated in any desirable mani ner and is thereafter coiled upon a spindle 10.

' gether as. `tor example,

The pad portion 8 may now be dipped into a suitable hair treating solution. or if this portion of the article be previously impregnated with chemicals it will only be necessary to dip the sheet 8 into Huid in order to render the treatment efficacious. Thereupon, the entire pad is coiled properly around the tress of hair. care being taken that la portion of the sheet 7 extends beyond the pad proper so that a clip 11 may be applied thereto to close the same to provide a seal, preventing the escape of steam towards the scalp of the person being treated. The pad is enclosed in a heater diagrammatically indicated at 12 and the treatment may now begin.

Obviously, the treatment will proceed inthe usual manner, it being noted that due to the relatively high moisture-absorbing and retaining qualities of lthe pad, that a proper treatment will.. at all times be assured. Also, obviously` after the treatment has been completed and the pad attached it will be found that the latter, and particularly the portion 8 thereof, will be unfit for further use', rendering it necessary for an operator to discard the In the form of device shown in Figures 3 and 4. an exterior sheet 13 is employed which extends materially beyond the pad proper. indicated at 14these elements being secured toder that all danger in connection with the use of the pad mav be avoided. the sheet 13 is im pregnated with a suitable tireprooiing substance such as. for example. acetate cellulose. In fact, according to the present invention, it is preferred that such impregnation may be effected at the time of imprinting -the exterior sheet of the pad. in which case the tire-proofing substance will. as has been indicated at 16, penetrate the upper surface of the layer 13 to a sufficient depth to assure against accident. In Figure 4 it will also be noted that the pulp paper, i. e. the pad proper. preferablv embraces. in its bodvftibres 17 which may be of of cotton and which will serve to prevent a disintegration or tearing of the pad during its initial handling before. or during treatment. It will be understood. however. that such reinforcement will in no way influence the fa ct that the pad may not be employed repeatedly in the treatment of diierent persons hair.

Thus, among others. the several obiects of the invention specificallv'aforementioned are achieved. It is intended that numerous changes in construction may be resorted to" without departing vfrom the spirit of the in venticn.
