6 Claims. (Cl. 132-36.1)

This invention relates to improvements in hair waving devices, and is more particularly directed to a protector unit made of readily destru-ctible material suitable for single application.

Up to the present time, considerable dificulty has been encountered in the industry by virtue of the successive and continuous use without cleaning or sterilization, of curlers, wrappers and protectors, with resultant complaint by fastidious customers.

It is an object of this invention to provide for a hair waving assembly, and particularly a protector unit therefor, incorporating a separable hair engaging or gripping member, which is constructed of readily destructible material of low cost suitable for single application.

These and other advantages, capabilities and features of the invention will appear from the subjoined detailed'description of one specific embodiment thereof illustrated in the accompanying drawings, in which Figure 1 is a perspective plan view of the base of the protector unit forming the subject matter of this invention.

Figure 2 is-a further perspetcive plan view of the same as spread for the reception of the ab sorbent hair gripping element of the unit.

Figure 3-is a rear view of the base of the protector unit.

Figure 4 is a plan view of the blank for the hair engaging element of the protector unit as scored and cut.

Figure 5 is a perspective plan view of the hair gripping engaging blank as folded.

Figure 6 is a perspective plan view of the protector unit with the hair gripping member thereof in position on the base.

Figure '7 is a perspective view .of a complete hair waving assembly incorporating the protector unit as applied to the head of a subject.

Figure 8 is a side elevation in section. takenalong lines 8-8 of Figure 7.

The protector unit of a preferred embodiment of this invention comprises a base member, a separable hair engaging or gripping member mounted in such base member, both applied in association with mandrel and enclosure wrappers to form a hair waving assembly.

Referring to the reference characters in the drawings, the base member A of the protector unit comprises an elongated strip of paper board or similar molded and preferably porous and non-heat conducting material, slitted longitudinally as along 23 from one end thereof to a terminal in zone 2| adjacent the other end thereof, thereby defining legs 22a and 221), which may be'laterally spread from one another to a slight degree to define an angular slot leading from the terminal ser ing as an apex, asshown in Figure 2.

A pair of mandrel supports comprising aligned upstanding cradles 23a and 23b are mounted respectively on leg 22a adjacent the open end of ihe base defined by the slit 20, each of the cradles being carried on a stem 24 from which extends pronged legs 25 for fastening the supports to the base.

As shown in Figures 1 to 3, there are formed respectively on the outer sides of

legs

22a and 22b,'and adjacent the'open end of the base defined by the slit Zil and in alignment with one another, transversely extending slit Zea and angular notch 26b. A-resilient clamping member, preferably an elastic, 21, is inserted along its length within slit 26a, for firm frictional mounting at a segment of itsperiphery, and is adapted upon being stretched or tensed to extend across

andsurround legs

22a and 22b as it enters into notch 2611, thereby drawing the legs towards one another sufficiently to substantially seal the slit 2%! separating the same.

In the preferred embodiment of this invention; as specifically illustrated in Figures 4 to 8, there-is mounted within-the slit 2!) an absorbent and pliable hair engaging member B shown respectively in blank form in Figure 4, in folded form in Figure 5 and in associated assembly form in relation to the base of the protector unit in Figure 6.

The hair engaging member is formed of a blank of pliable absorbent paper pulp or similar material and as shown in Figure 4 is scored along parallel. lines 28a-and 281) from one end thereof to a pointwadjacent the other end, and is cut along the .parallelv lines aforesaid from such point to the other end to form slots 29c and 2%; intermediate of the parallel scoring lines there is formed-a narrow slit 3i! extending from thejirst namedend to a point adjacent the other end, from which point an aligned scoring line (iiis directedto the other end. of the blank; the entrance end of the slit 35! being arcuately out, in opposing directions as at 32.

As shown in Figure 5, the scored and cut blank is folded along the three scoring lines 23a, 28 and 3! to define a structure wherein this member comprises adjoining hair gripping walls 33a and 33b upstanding from supports Ma and 3%, the respective walls being merged along scoring line 3| to form a shoulder 35 which extends vertically above a vertically extending cutout 36 defined by the spacing between the respective sides of each of the slots 29a and 2%.

To assemble the protector unit, the base member A is spread, as shown in Figure 2, and the hair gripping member B of Figure 5 is slid into the slit 2i], with the

walls

33a and 33?) thereof upstanding within the slit, the supports 34a and 34b beneath and adjacent the underfaces of

legs

22a and 22b, the shoulder 35 thereof extending over a portion of the zone 22 of the base and longitudinally beyond cradle 2319, which is disposed between the vertical reaches of the slot 33; the member being of such length that the arcuate portion 32 thereof extends longitudinally beyond cradle 23a.

In use, and referring particularly to Figures 6, 7 and 8, the protector unit incorporating the base and hair gripping members is spread open along the slit 2U similarly to the showing with respect to the base member alone in Figure 2, but at this time the respective Walls and supports 33a and 3411 on the one hand and 33b and 3% on the other are displaced with

legs

22a and 22b of the base; a tress of hair H consisting of several strands is interposed between the spread legs and walls, and elastic 2'! displaced and stretched from the position of Figure 2 to envelop the legs, supports and upstanding hair engaging walls aforesaid, adjacent cradle 2311 so as to draw the legs and hair gripping walls towards one another and substantially seal the slit 25 A non-reusable exothermic mandrel 31 of the character shown in my application, Serial No. 370,376, filed January 27, 1941, and about which the tress of hair is wound, is mounted in the cradles, an absorbent pad 38 incorporating hair waving material is wrapped about the mandrel 31 and the hair engaging walls Zita and 33b; and a water-proof wrapper, as for example, tin foil or waxed paper 39 or the like, is wrapped around the various elements disposed above the

legs

22a and 22b of the base to form a complete enclosure for the same; and the entire enclosed assembly is locked by clamp 49 as shown respectively in Figures 7 and 8.

As heat is developed in the mandrel, and the hair wound on the mandrel is subjected to heat and vapor developed within the assembly, the upstanding opposing hair gripping walls 33a and 33b being of porous and absorbent material, are wetted by the vapors developed and become softened and expand and form a substantially vaportight sealing zone for the entire contiguous areas thereof along and between which extend the hair strands of the tress wound on the mandrel, this sealing effect being concurrent with that caused by the tension imparted to the hair gripping elements when the same are drawn towards each other by virtue of the action of the elastic 21 enveloping legs 23a and 23b.

Each and every element of this assembly, which in any way is in contact with the hair of the subject, is non-reusable and destructible, thus to provide for sanitary, single application in processes for permanently waving the hair, along the lines of my application, Serial No. 277,135, filed June 3, 1939, of which this application is a continuation-in-part.

Although I have described the assembly as being non-reusable and destructible, it is within the province of this invention to apply a protector unit wherein the slitted base may be formed of material capable of reuse in conjunction with an interchangeable non-reusable head engaging or gripping member readily mountable therein.

t is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.

I claim:

1. A non-reusable scalp protector for use in permanent waving and made of readily destructible material suitable for single application, comprising a slittedbase, a hair gripping element separably mounted on said base, and having upstanding walls extending through the slit thereof, and resilient means for drawing the portions of the base bounding the slit and the upstanding parallel walls of the hair gripping element towards one another, whereby to lock the hair gripping element within the slit and to seal the slit.

2. A non-reusable scalp protector for use in permanent waving and made of readily destructible material suitable for single application, comprising a base having a longitudinal slit open at one end, a hair gripping element comprised of a strip of absorbent material folded to provide parallel upstanding hair gripping surfaces, slidably mounted on the base with the upstanding gripping surfaces thereof extending through the slit, and means for drawing the portions of the base adjacent the open end of the slit towards one another, whereby the upstanding hair gripping surfaces of the hair gripping element are drawn towards one another, to seal the space therebetween and the slit of the base.
