UNITED STATES PATENT OFFICE 2,051,331 mans-res roa some mm wmn N. Vanatta, Ontario, Calif. Application May :4, 1935, Serial No. 23,277

4 Claims. (cl. 132-36) This invention relates to "permanent waving of hair by the aid of heat; and more particularly to apparatus for use in connection with such methods.

This application is a continuation in part of a prior application filed October 24, 1934, in the name of Willis N. Vanatta, under Serial No.

749,789, and entitled: Apparatus for curling hair.

It is now common to utilize in permanent hair waving, a protector that serves the dual purpose of clamping the strand of hairto be curled, adjacent the scalp, as well as of shielding or protecting the scalp from the heat generated by the heaters.

It is also well-known to provide a curling rod upon which the strand of hair isso wound thereon, being held by the protector on that side thereof that is opposite to the scalp. Then a pad carrying a suitable solution may be placed over the wound hair on the curling rod. The application of electric heat can then be accomplished, as by the aid of a pair of electrically heated jaws embracing the pad placed over the hair.

It is one of the objects of this invention to improve in general, apparatus of this character.

It is another object of this invention to make it possible to maintain the scalp at a more comfortable temperature during the application of heat, and without the necessity of creating a cooling draft upon the head.

It is still another object of this invention to provide a protector so arranged thatair can freely circulate past the parts of the clamp, thereby ensuring that the scalp will not be subjected to any uncomfortable degree of heat.

This invention possesses many other advantages, and has other objects which may be made more easily apparent from a consideration of one embodiment of the invention. For this purpose there is shown a form in the drawing accompanying and forming part of the present specification. This form shall now be described in detail, illustrating the general principles of the invention; but it is to be understood that this detailed description is not to be takenin a limiting sense, since the scope of the invention is best defined by theappended claims.

Referring to the drawing:

Figure 1 is a view, mainly in section, of apparatus incorporating the invention, shown as in use;

Fig. 2 is a top plan view. partly broken away, of a protector clamp incorporating the invention;

Fig. 3 is a side elevation thereof;

Fig. 4 is a pictorial view of a curling rod utilised with the invention;

Fig. 5 is an end elevation of the protector; and

Fig. 6 is a pictorial view of a protector felt pad that may be used in connection with the apparatus.

The scalp l. of the user isindicated in Pig. 1. A strand of hair 2 is shown as being in the proces of treatment. This strand of hair is clamped by a protector 3, adjacent the roots of the hair. A felt pad 33' (Figs. 1 and 6) can be interposed between the protector 3 and scalp I to provide additional shielding. This pad can have a slit 34' through which the strand 2 passes.. The length 'of the slit 34' also serves to define the width to, as by a series of intermediate posts 6 and end posts I, which posts are preferably all made from insulation material. Pins or rivets II can pass through these posts. The separation between

bars

4 and 5 is considerably greater than the thickness of either of these bars; and since the posts 6 and I are spaced apart, cooling air can easily circulate between the posts and in every direction between the bars. These features are of considerable importance, as by their aid, it is assured that the clamp can be kept cool.

One edge of bar 5 is turned over toward bar 4 to form a rounded portion 3. This rounded portion cooperates with the corresponding edge of bar 3 to form a groove-like space past which the strand of hair 2 is drawn. Furthermore, the portion 8 has a lower edge spaced from bar 4, to leave an unimpeded passageway for air past this lower edge. The portion l is formed with a convex outer surface rising to a height slightly above the top surface of that part of bar I which rests on posts t and l,- as shown most clearly in Figs. 1 and 3 by reference character I.

The strand is held in position in the groovelike space between the two bars 4 and I, by the aid of another clamping element 3. .This clamping element comprises a metallic bar 9' overlaid with a yielding sleeve II, as of soft rubber. The

strand 2 is thus held tightly between the sleeve II and the adjacent portions of bars 4 and I. The rubber sleeve III serves further to shield or protect the scalp l'f'rom transmission of heat to the scalp I. from the source of heat utilized in the process.

The manner in which the clamping element 3 is supported and heldin open or closed position can best be described in connection with Figs. 2,

i t 3, 4 and 5. The bar 9' at one end carries a clevis ll, pivoted to the end of a flat strip l2 held between the end spacer posts I and bar 4. The free end l3 of bar 9 is flattened and has a slight concavity I4 for coaction with a cam surface II on a catch member l8. This catch member I6 is provided with a finger grip ll. It is pivoted as by the aid of a pin l3 between a pair of spaced bars or links iii. The inner end of the spaced bars or links I! are pivoted on a pin 20 passing through the right hand spacer post I as viewed in Figs. 2 and 5. A

The open position of clamp 3 is illustrated in dot and dash lines in Fig. 2. In this position the bars l9 have been retracted by rotating them about pin 20 in a clockwise direction. In order to'close the clamp, the end ll of bar 9' is passed between the bars l8, and catch member I6 is rotated in a counterclockwise direction so as to urge the cam surface It into the cavity l4.

The protector and clamp 3 also serves to support the curler rod 22 after the strand of hair 2 is wound thereon. This curler rod is shown to best advantage in Fig. 4. It includes a metal member having a reduced center portion 23 and a hinged hair retaining member 24. The inner surface of member 24 is curved to correspond generally with the contour of the curler rod 22. Furthermore, member 24 can be hinged as by a pin 25 adjacent one end of the rod 22. In using After the strand of hair 2 is wound in the rod 22 in this manner, it can be held in place by the aid of the upright portions 28 and. 29 of bar 5. These upright portions are provided with appropriate slots cooperating respectively with the round end 30 of the rod 22 and the square portion 3| of the rod 22. As is now well understood in the art. the square portion 3| is connected to rod 22 through a one way clutch arrangement, whereby after the curler rod 22 is placed in position as shown in Fig. 3, the strand of hair 2 can be wound more tightly around the rod 22 as by placing an appropriate instrument into the apertures 32 located adjacent one end of the rod 22, and turning the rod 22 with it, while portion 3| is stationary. The slot accommodating the square portion 3! is just wide enough to permit electrical heating elements are disposed therein to provide the necessary degree of heat.

After a suitable period. the heater 34 can be removed and the strand 2 can be unwound.

The intensity of heat provided by the heater 5 34 is such that the scalp I must be shielded therefrom. This is accomplished as stated heretofore by the clamping mechanism 3 and felt 33'. By utilizing a metallic bar I spaced at all points from the-heat insulation bar 4, there is a greater l0 assurance that no unmmfortable heating can occur. This is due to the provision of a wide air and clear space between the

bars

4 and 5. Furthermore, there is a better opportunity for transfer of heat through other channels than through the scalp l by this construction. The scalp I is kept comfortable and there is no necessity of directing a blast of air between the protector structure 3 and the scalp l.

Furthermore, the provision of knurled surfaces20 26 and 21. ensures against slipping of the rod 22 during the hair winding operation.

I claim:

l. A protector for use in connection with a source of heat, having a pair of clamping mem- 2 bers, one of said clamping members comprising a pair of bars, forming a groove between them for cooperating with the other clamping member, and one of said bars being made from heat insulation material, and the other bar being made' from raetal, and widely spaced from the other bar, and curved to form an exterior convex surface along ,a side of the bar, the lower edge of the curved portion being spaced from the insulation 35 bar.
