This invention relates generally to apparatus for use in conjunction with a heater for'waving' hair. It relates particularly to the Waving of hair by. the croquignole Wound hair is positioned substantially parallel to the scalp.

It is the general object of this invention to provide' a method for' the waving of hair Without having an undesirable sensation of heat occurrin u on thescal durin the g P P g process and to devise novel means for accomplishingV this; A

Further objects of this invention will appear in the following description in which I have set forth the preferred embodiment of my invention. It' is to be understood that the appended claims are'to be accorded a rangeof equivalents 'consistent with the state of the prior art.

ra manner that the transmission of heat to the scalp is minimized and reduced to such an extent that the sensation cent the scalpv is overcome. Whilethe apparatuses utilized heretofore have overcome this sensation by the use of, protectors to v upon which the hair of heat adjasome extent it has not been overcome substantially entirely. In accordance with my invention I provide means for reducing the transmission of heat to the scalp to such a degree as practically obviates the sensation. This means may be employed with any of the convenient form of apparatuses utilized in waving hair.

In that type of apparatus which I have shown in the drawings, a protector 9 in- 60 cludes clamping means formed by elongated members 11, hin edly secured together at 12, and adapted toe locked together by locking means indicated generally at 13. The elongated members 11 are usually formed 65 of metallic strips bent to provide curved U- shaped sections 16 in which are positioned strips 17 of a resilient material as soft vulcanized rubber. To reduce in some degree the transmission of heat .to the scalp, the metallic strips are referably faced with Wood strips 18 to w ich they are secured by pins 19. The lower faces of the wood strips are covered with lengths 21 of felt or other equivalent soft material.

The locking means 13 conveniently comprises a locking lever 22 carried b one of the metallic strips 11 and adaptedI to slip over projecting end 23 of the opposed metallic strip 11. Cam lever 24 pivoted upon the 80 locking lever is adapted to contact with the cooperatively formed projection 23 and to be moved as shown in Figures 2 and 6 to lock the respective members in hair clamping position.

To provide for the heating of the hair in Wound form I preferably employ the clampingy means with a mandrel or spindle 26 can be wound. This mandrel is preferably substantially circu- 90 lar in cross section and has an intermediate portion 27 of reduced diameter. Lug 28 extending from one end of the mandrel provides convenient means for its rotation by an operator while the ratchet teeth 36 are 95 adapted to cooperate with a ratchet or pawl 37 carried by the clamping apparatus as will presently be explained.

To position the mandrel on the protector 9 I provide upstanding support members 38 H0 and 39. Support member 38, suitably a ertured to receive the lug end of the man rel, is formed integrally with a plate 41 provided upon and spaced from the metallic.

strip.` The locking lever is (provided with a supporting end 42 adapte to cooperate with the support member 39 which extends from plate 41 to form support means for the other end of the mandrel. The awl 37 is secured to the upper plate 41 a jacent the member 39 and is cooperatively arranged with teeth 36 to prevent rotation ofthe mandrel in one direction. W-

A second upper plate 44 is secured to the metallic strip 11. This plate 44 is curved to form a guide lip 46 over which the hair extends and which prevents it being cut.l

In utilizing my apparatus, a com aratively wide strand of hair is first place between the members 1l, when these members are separated as shown in Figure 5; The members are then brought together and clamped inv ostion upon the strand of hair b 'the lo ingmeans 13, the members then ing practically parallel to the scalp. As 1s shown in Figure 6, the engaged strand of hair is wound upon the mandrel 26, the mandrel then being seated upon the

support members

38, 39 and 42. As` the .hair is wound upon the mandrel and positioned in the several support members, ratchet 36 engages the pawl 37 As the mandrel is seated in the supporting members, additional rotation of the mandrel b the operator serves to'tension the hair while the pawl 37 ratchets over the teeth 36. The engagment of the pawl preserves the tension in t e wound hair when nally positioned in'the support members.

It has been my observation that the sensation of heat on the sca'l is due' in large measure to the passage of eat and of va ors arising from the liqmd used on the hair uring the waving down through the space between the members and also down along the strand of hair to the scalp. This has occurred even though rubber liners have been/ -used to gris the strand of hair.

In .accor ance with my invention I provide. means for use in connection with the hair wavin appliance for minimizin this sensation'o heat upon the scalp. T is' is :accomplished by providing a sheet of pro er material which is positioned with the ot er apparatus in such a manner as to extend beneath the wound spindle. A material which gives good results is felt, which serves as a heat insulator and as an absorber off' vapors. The felt is usually in the form of a strip or sheet 47. 1

The hair is wound about the mandrel or spindle, the felt strip being wound in with,

it so that when the mandrel is finally positioned upon` the supporting members, the felt extends about thefmandrel contiguous to vthe hair and across the members as is shown in Figure 7 When the heating element, designated generally at 48, is positioned about the mandrel to heat the hair, a sheet 49 of waxed paper beinglinterposed between them, until it sets into t ve deslred wave, the sensation of heat upon the scalp is substantially prevented` by the presence of the felt strip which extends contiguous to the wound hair and across the s ace left unoccupied by the strand of h'air Ibetween the elongated members 11, so that heat and hot vapors vdo not pass down to the scalp. Further, when vapprizable liquids such as oil or` water are employed during the heating of the hair, the felt absorbs and so prevents the passage of heated va ors to the scal or adjacent to the scalp, t heat.

To facilitate positioning of the felt I have employed means for securing it on the protector 9. A form of such means is illustrated by a cli 51 which is constructed of sheet metal to ave prongs 52 for extension between the metallic strip 11 and the plate 41. The clip is conveniently joined to the felt strip by crimping an'edge 53 overv to engage the felt.
