HAIR-WAVING PAD.

Application filed April 27, 1923. Serial No. 635,127.

To all whom it may concern:

Be it known that I, LEON INoRAssIA, a citizen of the United States, and resident of New York city, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hair W'aving Pads, of which the following is a specification.

The invention relates to an improved hair protecting pad for use on a persons hair in the method of imparting a permanent wave to the hair, and the invention herein constitutes a development of the inventions defined in my two applications, Serial No. 546,869,.Composition of matter, filed March 25, 1922, and Serial No. 611,730, Hair waving pads, filed January 10th, 1923.

In the earlier of the above-identified ap plications-there is featured the use of min-- eral .oil in combination with the use of certain known protecting salts, and which oil was shown to possess certain hair protecting values and assisted the action of the salts inminimizing the deleterious action of the extremely high temperature heat employed in the art of permanent hair waving.

In the latter of'the 'above identified applicati ns there was featured the utilization of the oil composition as a filler for an absorbent material such as felt, and which filled fabric was cut to shape and used as a protecting pad between the coiled hair and the electric heater usually employed in permanent hair waving operations.

While this pad with its combination of dried salts and small amount of oil is admirably suited for its intended purpose, where there is not an extensive time. delay between its manufacture and its use, it has been found that pads prepared in the manncr suggested in the preceding applications have a disadvantage in that they become stiff and frangible when permitted to remain in a dry condition over a long. period of time before being used. Apparently the impregnating salts used in these pads become crystallized after the pads have been extensively dried over a long period of time and when so dried easily break.

Accordingly, the primary object of the present disclosure is to provide a pad which has all of the advantages inherent in the pads formed by the method defined in application, Serial No. 611,730,such as convenience in applying the salts with oil to the hair and w ch at the same time can be maintained indefinitely without losing its flexible and pliable characteristics.

Broadly, I have found that it is necessary merely to feed the pads through pressure rollers, after the pads have been air dried, and that there results an article which can be maintained intact over a long period of time and which can then be used without danger of breaking, cracking or otherwise losing its original form.

Instead of adding the oil ingredient to the salt solution in which the pad is dipped following the disclosures in the previously .fiied applications, a better and cheaper form of pad may be provided by omitting the oil from the solution of salts in which the felt is dipped and by adding instead a thin film of oil to the pads after they have become dry.

Described more in detail, one practical means which has been tried successfully is to prepare a water solution of any of the usual well known hair preserving substances, such as borax and sodium thiosulphate. The solution is boiled and while boiling, a sheet of felt or other suitable absorbent fabric is dipped into the boiling liquid. After immersing for a few minutes, the pads or sheet are withdrawn from the boiling solution and subjected to an air drying opera tion until the pads are dry to the touch. Before they are permitted to stifien' into a crystallized cake, the pads are fed through any suitable form of presser rollers, and there is at this time applied to one, or if desired both sides, a thin film. of oil, such as the mineral oil suggested in the preceding applications.

One convenient means of feeding the 011 is to cause one of the rollers to rotate in a bath of the oil and the roller thus acts as a feed roller to supply oil to one side of th fabric simultaneously with the pressing operation, all as is well known in the art of roller feeding of liquids.

The action of the rollers is apparently to effect a compressing of the salt impregnated felt, and a breaking up of the cohesive shell defining the surfaces on opposite sides of the fabric. The rollers also act a parently to force the oil through the abric with a greater proportion of oil adjacent the surface to which it is applied than there is adjacent the opposite surface. It has not the oil is the surface which is applied directly to the hair in the process of waving the hair.

There results from this method of preparing the pads an article which contains a substantially dry hair protecting salt, or salts, which is uniformly distributed throughout the thickness of the fabric and which fabric has at least one side impregnated with oil. This pad can be handled without danger of breaking or cracking months after it has been prepared and apparently maintains its characteristics indefinitely, or at least as long as the all-salt pads now in general use.

In the accompanying drawing. there' is disclosed a padprepared in accordance with the method above described and Fig. 1 is perspective view showing such a pad wrapped about a coil of hair and disposed in operative position in a conven tional form of heater and Fig. 2 is a perspective view of the pad p1 ior to being wrapped about the hair coil..

In the drawings there is shown a pad 10 for use in waving hair and constituting a physical embodiment of theinvention.

In Fig. l-the pad is wrapped about a strand of hair 11 which is coiled on a curling rod 12. The assembly thus formed is enclosed in an electric heater 13.

The pad 10 is formed of a layer of absorbent material such as felt impregnated with a water solution of protecting salts and when dry passed through presser rollers.

Both sides of the pad are impregnated with a thin film of oil with a greater proportion of oil adjacent the surface l lthan the opposite surface. As shown in Fig. 1 the pad is applied with the side 14. having the greater amount of oil adjacent the head.

Having thus described my invention, I claim:

1. In the art of preparing a pad for use in subjecting hair to a waving operation, the method which consists in boiling a solution of a hair preserving substance containing borax, soaking a fabric with the boiling solution, subjecting the soaked fabric to a drying operation and subjecting the dried fabric to the pressing action of a roller.

2. In the art of preparing a pad for use in subjecting hair to a waving operation, the method which consists in boiling a saline solution of a hair preserving substance, soaking a fabric with the boiling solution, subjecting the soaked fabric to a drying operation and subjecting the dried fabric to the pressing action of a roller having a layer of oil on the surface engaging the fabric.

3. In the art of preparing a pad for protecting hair from the deleterious action of the high tempered heat employed in the method of permanent hair waving, the process which consists in saturating a fabric with a solution of hair protecting salts, drying the fabric so saturated, and subjecting the dry fabric to pressure. v

A. In the art of preparing a pad for protecting hair from the deleterious action of the high tempered heat employed in the method of permanent hair waving, the process which consists in saturating a fabric with a solution of hair protecting salts, drying the fabric so saturated, and subjecting the dry fabric to the action of a presser roller. 1

5. In the art of preparing a pad for protecting hair from the deleterious action of the high tempered heat employed in the method of permanent hair waving, the process which consists in saturating a fabric with a solution of hair protecting salts, drying the fabric so saturated, and subjecting the dry fabric to pressure, and while feeding a layer of oil to one side of the fabric.

6. The method which consists in saturating a fabric with a hair preserving substance containing a solution of a sodium salt, and subjecting the fabric so saturated to compression.

1 7 The method which consists in dipping an absorbent material in a saline solution of a hair preserving substance, air drying the material with its absorbed substance, and passing the dry material between presser rollers.

8. The method which consists in dipping an absorbent material in a saline solution of a hair preserving substance, air drying the material with its absorbed substance, and passing the dry material between presser rollers while feeding a film of oil to one of the surfaces of the material.

9. A pad for use in waving hair including a fabric containing a dry, hair protecting substance diffused throughout the fabric in substantially uniform amounts and said fabric saturated with oil disposed in greater predominance adjacent one surface than adjacent the opposite surface, whereby one surface will be more oily to the touch than the other surface.

10. A flat flexible pad for use in waving hair including a layer of felt containing borax powder and containing oil disposed in unequal amounts throughout the thickness of the felt with more adjacent one surface than adjacent the other surface.

11. A flexible pad for use in waving hair, including a heat resistant material saturated on the side adapted to bedisposed in contact with the hair with an oil.
