Opinion

LINDLEY, District Judge.

Defendant appeals from a judgment holding valid and infringed Winkel patent 2,-051,063, August 18, 1936, and Evans and McDonough reissue patent 22,660, August 7, 1945. It contends that neither patent is valid and that if either is valid, defendant has not infringed.

Each patent has to do with the art of hair curling, especially that involved in creating “permanent” waves. Needless to say, by the very nature of things, this art is of ancient origin. It involves, so far as “permanent” waves are concerned, winding the hair on separate curlers; applying a waving lotion to the curled hair; heating the moistened hair wound about the curlers for a pre-determined period of time and, finally, cooling the hair before removing it from the curlers. An operator practicing the earlier art procured the essential heat from an external source, usually an electric current, thus necessitating the use of relatively complicated apparatus. But the art with which we are concerned progressed a step further by eliminating any external source of heating and providing heat by chemical reaction in material wound about the hair after it had been curled. Thus, Winkel, in the first patent, stated that his objectives were to provide an operation whereby the use of an external heating device is avoided and to supply a permanent waver which does not require any fastening means for maintaining it intact on the hair while the latter is being treated. As interpreted by plaintiff’s expert, he provided a hair waving pad which can be used to enclose a preformed tress, the pad being so constructed as to evolve from exothermic chemical within itself sufficient heat to wave the tress, the evolution of the heat occurring as a result of moistening the chemical.

It is undisputed, therefore, that Winkel successfully did away with external means of heating and avoided the use of a metal clamp to hold the hair and waver in place. [610]*610This he accomplished by providing in a single unit a backing sheet having a sachet secured adjacent one edge thereof. This sachet, of impervious material, such as metal foil, contains a chemical such as calcium oxide or an oxide compound intended to be combined with a liquid such as ammonium hydroxide to develop heat sufficient to fix the wave in the hair relatively permanently. He attached, also, an apron, to be moistened by the aforesaid ammonium hydroxide, and prescribed that, before wrapping the pad around the curled hair, the sachet containing the chemical be perforated. When -the pad is then wound around the hair, next to the hair is the apron, moistened as aforesaid by the ammonium hydroxide;- then around this is wrapped the sachet containing the chemical so that the sachet having been perforated, the moisture from the apron generates the heat necessary to effectuate the desired result. When he has thus wound around. the curled hair the apron, the sachet and the outer covering, integral in one continuous flexible pad, so that wrapping is facile, he fastens the pad, thus wound around the hair, by twisting the ends of the outside enveloping metal foil above and below, the pad on the curler, thereby eliminating any necessity of a clamp and providing, as he said, effective means to prevent the escape of vapors generated -by the chemical reaction. This is his alleged invention.

Winkel was preceded in the art by Lackenbach 18,346 and Frederics 1,596,247. Lackenbach claimed a device described as a flexible rectangular absorbent strip containing hair treating substance, -adapted to be wrapped about' hair wound upon a curler. He attached to the strip a sheet of water-proof material, adapted to be wrapped around said strip after the latter has been rolled about the hair on the curler, so as to form a cylindrical covering for said strip, and -an integral tab upon said strip and sheet, the tab being adapted to be folded upon the hair before the rolling operation is commenced.

Frederics, too, described an appliance for creating a permanent wave. He recognized that the first step was to curl the hair about curlers and mentioned -that one -of the methods previously practiced was to impregnate a strip of -absorbent material with a fluid having a tendency to soften the hair under the influence of heat or with a pasty mass of which borax had been the principal constituent part. He described other methods. He pointed out his objection thereto and claimed that he had eliminated alleged defects by providing a device which is proof against the escape of steam through its side walls and ' prevents hot water from escaping. He claims a device comprising a flat envelope formed of flexible material, one face of which is provided with a plurality of interstices, and has a strip of impervious fire-proof material secured there^ to, adapted to be wrapped around the latter to form a cylindrical covering when the envelope is wrapped about a tress of hair upon a curler. But he, too, described and claimed a curling pad dependent upon heat from an external source. The teaching of each of these patentees is pertinent only to the extent that they disclose prior conceptions of curler pads adapted to be wrapped about the hair before heat is applied.

Sartory 1,565,509 likewise preceded Winkel. In this patent we find for the first time the idea of elimination of heat from an outside source and the conception of a pad containing a sachet or envelope in which is inserted a chemical, which, when subjected to moisture, will generate the necessary heat. His application was filed in 1924 and the patent issued December 15, 1925. Sartory stated as one of his objectives, the provision of a heater in which -the heat required for the steaming operation was to be obtained by exothermic reaction by placing a chemical substance in the sachet container upon which water was to react to produce the heat requirement. This chemical was placed in the heater during manufacture and the water brought in contact with the chemical substance at the time of the curling operation. He specified a stratum of chemical material which would react exothermically with -a liquid reagent. He applied water to the heating pad by enveloping the latter in cotton, wool or any like fibrous material which -can be saturated with water. His pad, therefore, had an inner annular layer of chemical material and an outer layer of fibrous material. .This [611]*611was wrapped around curled hair as in Winkel.

The difference between the two patents lies almost entirely upon one fact. Sartory placed his moistening element outside of the heating element while Winkel placed his on the inside. To our minds in this distinction lies all vital differences between the present parties. It seems quite clear to us that the object and purpose of Sartory was exactly the same as that of Winkel, — first, to avoid an external source of heat and the necessary machinery supplying the same; second, to supply, in lieu of such external source of heating, a pad containing chemical of such character as, when brought in contact with water, would result in a chemical reaction generating the necessary heat. Each of the patentees had this conception; each of them taught it; each of them applied it. In their respective conceptions, they differed only as to the relative orders of application of the heating element and the moistening element. One placed the moistening element on the outside; .the other placed it on the inside. Thus it is clear that Winkel was not a pioneer worker in the art.
