HAIR CURLING PROCESS Dec. 20, 1932. A. NEFZGER Filed May 19, 1952 Bf WMM Patented Dec. 20, 1932 UNITED sTATEs PATENT oFi-icE Application #led lay 19,1938, Serial No. 618,308, and in Austria .Tilly 18, 1981.

This invention relates to improvements in hair-curling processes, and consists essentially in the emplo ent of a sheet of metal foil or other material conductive of heat and at the same time impervious to moisture, and of means enabling this sheet of material to` be wound upon a curler simultaneously and in company with a strand of hair, for the .combined purposes of forming an effective 1 and fluid-ti ht encasement for the strand of hair to be ormed into a curl, or forming a protective covering for the completely wound curler, and. of conducting an distributing the heat applied rapidly and evenly in between the turns of t e hair wound upon the curler. The usual type of protective covering for the hair curlers used in permanent waving consists of a sheet of flexible material which is wrap d around the finished wound curler, and t us only encases the latter loosely, so that an-extremely defective and inadequate seal against the escape of the steam is obtained. A type of flexible protective covering is also known which is ada ted to be clamped together with a wisp of air in the head-protecting clip, and to b e wrapped about the wound curler as a final covering when all or the greater part of the hair has been wound ulpon the in of the curler; the hair and t e lappe covering sheet are then tightened i together on the curler before heat is appli The main objection to these known of curler-covering is the fact that the hair is unevenly heated, the hair in contact with the curler in and the hair lyiililg uppermost on the curler being more rapi y and more intensely heated than the intermediate turns, which gives rise to unevenness in the finished waves.

The present invention provides a protective covering which entirel above-mentioned drawback is result being achieved by virtue of the fact that the ilexible sheet is clam alo one edge together with the wisp of air in t e head-perlitceting clip, the remainder of this sheet g subuently wound simultaneousl with the hair, thus becoming embedded tween the turns or layers of hair on the curler.

obviates the .even and uniform.

The invention further includes a method of producing the described protective coverin ne form of construction embodying the invention is illustrated, by way of example,

4in the accompanying drawing, in which The protective covering proper consists of va iexible or supply sheet a of material, e. g.

metallic foil, which is permeable to heat but impervious to moisture, which sheet is adapted to be clam ed along one edge too gether with the moistened wis of hair b in a head-protecting clip c. This clip c is a known type of head-protecting or base clip consisting essentially of two jaws (which may be perforated, as shown in the drawing, 7 for ventilation) hinged together at one end and provided with a locking catch of any convenient type at the other end. The wisp of hair b isolated by the clip is wound on the pin d of the curler alone up to the outer edge of the sheet a, and fr om this oint on togetherA with this sheet, so that t e latter becomes embedded between the turns or layers of the hair upon the in. The completely wound curler is iixe in position to a protecting catch f on the head-protecting clip c, and tightened up by means of a locking device e, after which a saddle clip and a heater are fitted over the curler in a known manner. The leaf or sheet a which is laid between the turns of the hair on the curler, and which is stretched tight and assumes exactly the shape of the latter, forms a erfectl steam-tight protective covering w 'ch enab es the heating stage to be completed in a 9@ very short time, and also conducts the heat into the interior of the coil,and distributes the heat evenly therethrough, so that the finished curls or waves are particularly l I claim:

1. The method of curling hair by which a sheet of material which is conductive of heat and impervious to moisture is clamped along one edge together with a wi of hair in the headrotecting clip of a cur er, and is then woun to the end and tightened together with .the hair on the already partly wound pin of the curler.

2. A protective covering for hair curlers used in permanent wavin of the type comprising a flexible sheet o material which is conductive of heat and im ervious to moisture, such as metallic foil, 1n which the said sheet is adapted to be clamped alon one edge together with a wisp of hair in the eadprotectmg clip of a curler and to become embedded between the turns of hair upon the said curler when in the wound oondltion, as and for the purpose specied.

In testimony whereof I affix m si ature.
