9 Claims.

My invention comprises generally a hair waving pad of novel construction which is adapted more particularly for use in permanently waving croquignole wound hair, said pad including an outer sheet, an envelope containing an exothermic material, van inner sheet and an intermediate absorbent sheet interposed between the envelope and inner sheet.

My invention more particularly comprises a hair waving pad of the above character in which the outer sheet is of non-absorbent material, as parchment paper, the envelope is of impervious material as foil, the inner sheet is' of impervious material as foil, and the intermediate sheet is of absorbent material, as cotton fabric; the said inner sheet and envelope being perforated and the said intermediate sheet being moistened before the pad is used.

A practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents an inside plan view of the pad in its unfolded and unwrapped condition, a portion of the impervious envelope being broken away to disclose the exothermic material within the envelope;

Fig. 2 represents an inside plan view of the pad in its folded and unwrapped condition after the envelope and inner sheet have been perforated and the intermediate sheet has been moistened; corresponding corners of the inner and intermediate sheets being turned back;

Fig. 3 represents a side view of an apparatus for permanently waving croquignole wound hair with my improved pad in operative position therein;

Fig. 4 represents across section taken in the plane of the line IV--IV of Fig. 1;

Fig, 5 represents a top plan view;

Fig. 6 represents an end view;

Fig. 7 represents a side view of the combined clamp and shield forming part of the apparatus;

Fig. 8 represents an end view of the same;

Fig. 9 represents a top plan view of the combined clamp and shield;

Fig. 10 represents a'crosssection taken in the plane of the line X-X of Fig. 9, looking in the direction of the arrows; and

Fig. 11 represents a top plan view of the combined clamp and shieldin its opened position.

The outer sheet i of my improved pad is of some suitable non-absorbent material, such for instance as parchment paper. An envelope 2 of some impervious material, such for instance as foil, is attached to the inner face of the outer sheet 9. This envelope is somewhat shorter than the outer sheet i, leaving projecting ends for wrapping around the tress winding mandrel when the pad is put into use. This impervious 5 envelope 2 contains a suitable exothermic material 3, such for instance as calcium oxide in powdered form, which material when moistened will of itself generate sufiicient heat to impart aso-called permanent wave to the croquignole 10 wound tress when the pad encloses the same.

An inner sheet 4 of impervious material, such for instance as foil, is attached to the inner face of the outer sheet I at one end thereof.

An intermediate sheet 5 of absorbent mateit rial, such for instance as cotton fabric, is attached to the inner face of the non-absorbent outer sheet i at one side thereof and projects from the outer sheet at right angles to the inner impervious sheet 5. 20

Just before the pad is put into' use the inner sheet 4 and the inner face of the envelope 2 are perforated by means of a suitable implement. The intermediate sheet 5 is moistened, the perforated inner sheet t raised from the 25 envelope 2 and the moistened intermediate sheet 5 spread over the perforated face of the envelope 2. The perforated inner sheet l is then laid over the moistened intermediate sheet 5 and the moisture is caused to enter the perforatedg envelope 2 as by pressing the whole between the fingers. Due to the moisture the reaction of the exothermic material will start and will generate heat suflicient to impart a permanent wave to the wound tress to which the pad is applied.

In the present instance I have shown the pad as applied to a hair waving apparatus which forms the subject matter of my copending application filed of even date herewith, Serial No. 619,024; a brief description of which apparatus 40 follows:

The mandrel 9 on which the tress is to be wound in the croquignole manner may be of any well known or approved form, its squared end being denoted by Hi and its cylindrical end by ii.

The divided tress clamp comprises two sheet metal channelmembers i2 and i3 for receiving and holding the two tress engaging strips itand I5 of suitable yielding insulating material. 5 These clamp members It. and 13 are developed to form the divided shield, the shield members comprising the bottom 16. and I1 and the uprising sides l8 and I9. The clamp members l2 and l3-are'a1so developed to form the two members and 2| 01. a divided uprising ear having a slot 22 for the reception of the cylindrical end -ll of the mandrel. One of the clamp members, the clamp member l3, for example, is developed at the other end of the clamp to form an uprising ear 23 having a recess .24 for rotatably mounting the squared end ID of the mandrel 9.

A link 25 forms a hinge connection at one end of the clamp between the two clamp members. The other end of the clamp is provided with a link 26 pivoted to one of the members, the member I2, for example, which link is provided with a cam lever 21 for engaging the other member to hold the members in their closed position.

A pad 28 of felt or other suitable material is inserted between the tress clamp and the scalp.

In practice, the tress may be moistened, if desired, before or after it is wound on the mandrel. After the tress has been wound on the mandrel the pad -with its moistened intermediate sheet 5 and its perforated envelope and inner sheet is wrapped partly around the tress by inserting the sides of the pad into the shield, the sides of the shield serving to hold the pad in its operative position. It will be understood that the projecting ends of the outer sheet 4 of the pad are wrapped around the mandrel 9 beyond the tress.

As soon as the exothermic material in the envelope becomes moistenedthe exothermic action starts and the heat then set up within the pad imparts a so-called permanent wave to the wound tress.
