Application February 7, 1942, Serial No; 429,865 (Cl. 219-24) 6 Claims.

This invention. relates to improvements in ap paratus for permanently waving hair, and more particularly to electrically heated hair waving apparatus capable of use by a woman for home treatment of her own hair.

Various forms of electrically heated hair-wav ing devices have heretofore been employed, but in most instances they are so complicated that they require expert manipulation by beauty parlor attendantsand in all cases they demand especial precautions in order to avoid the danigers of burning orscalding ofthe hair and scalp. 7

Nevertheless, scalp burns are still of frequent occurrence, even under skilled hands,-due to accidental displacement: or'twisting of the heating elements so as to contact the scalp directly; or

so as to permit a jet-f steam to be discharged from the curl wrapper toward'the scalp.

In carrying out my-"invention' I provide a simple and economical form of heating apparatus,

including'one or more metallic hair roll clamps designed to be self applied to the hair, and positively held in proper position on the head by means of an electric heating device having an elongated handle, so as to avoid any danger of burns o'r scalds to the user.

The invention may best be understood byreference to the accompanying drawing, in which Figure 1 is a view illustratingthe method of use and application of my improved form oi hair waving apparatus.

Figure 2 is an enlarged perspective view illustrating one manner in. which a hair strand may be initially formed into a roll or curl preparatory to the application of my improved form of'heating apparatus. a i Figure 3 is an enlarged perspective view of a heating clamp shown in position to be applied to a hair roll or curl formed by the curling means shown in Figure 2. I

Figure 4 is an end view of the heating clamp, in closed position, with the heating element removed therefrom. l I

Figure 5 is an end view of the Figure 6 is a detail view of the heating clamp shown in longitudinal section, and showing how the removable heating element is inserted there- Figure 7 is a view in longitudinal section of a modified form of heating apparatus in which the clamp is permanently mounted on the heating element. f

Referring now to details of the embodiment of the invention shown in the drawing, the prinheating clamp, showing it in fully and partially opened position.

horizontally. extending plate cipal parts of the novel apparatus comprise a metal holding clamp l6 and an elongated heat-- ing element ll having a handle ii. In the preferred form illustrated in Figures 3 to 6, the hold in'g clampis detachably mounted relative to the heating element, and comprises two elongated jaw's l3, l4 suitably hinged for clamping action about a preformed hair roll or curl indicated.

generally at IS in Figure 3. i i

In the form of clamp shown herein, the jaws l3 and i l have similar integral finger pieces I6, ll extending upwardly from adjacent their upper margins, and suitably protected from heat byinsulating plates l8, 59 secured to the outer faces of said finger pieces. The hinged connection between said jaws comprises registering eyes 23, and 2i, 2! formed along the opposite side margins of said jaws and hinged together by'a pivot pin 22.. A coil spring 23 is mounted on the pivot pin with its extendedends maintained under ten,- sion so as to tend to urge the jaws-l3 and M to gether. The jaws are opened as usual by pressing the finger pieces toward each other. I

- As shown in Figures 4 and 5, the jaws i3 and M of the clamp l8 are preferably curved inwardly' toward each other from the hinged eyes 20 and. 2|, respectively. At an intermediate point on the inner face of one of said jaws, as for instance jaw !3, is secured a relatively resilient strip of metal formingan inwardly projecting 25, preferably curved in transverse section in an upwardly direction so as to define a longitudinal socket or opening :21 formed belowthe hinged eyes it and 2| I3and M for the insertion of the end of the cylindrical heating element H in closely confined but yielding metal-to-metal contact therein. At one end of thissocket a suitable stop is provided, herein consisting of an inturned portion or lug Z8 projecting from one of the jaws l3. Immediately below the curved plate 25 is mounted a second plate 3!} which is attached along the inner face of the opposite jaw hi and extends inwardly therefrom closely adjacent the lower surface of said curved plate. The arrangement is such that the plates 25 and 3% overlap each other throughout their length when the clamp is in closed position as shown in Figure 4, soas to form a partition adapted to conduct the heat from the heating element l l directly to the jaws l3 and I4, and also protect the hair roll from a more direct application of heat iromsaid heating element. When'the clamp is in open position .having the'handle I2 securedto its lower end.

The heating element and handle are relatively long so as to facilitate the use of the apparatus, as will now be described.

Preparatory to the application of my improved heating apparatus one or more strands or tresses of hair 3i which are to be treated are each passed through a protective shield or pad 32 of the usual form having a longitudinal slit 33 therethrough. The pad is then brought against the scalp. In

preparation for treatment the strand of hair is moistened as usual with a permanent wave or hair-treating solution. The exposed end of said strand is then rolled on a suitable curler which, in the form shown herein, consists of an elongated strip of cloth such as flannel folded upon itself to form'two lapping sheets 35;, 35. 'Along the folded end ofthe wrapper is disposed an insulating wire 36 having bendable end portions projecting at opposite sides of the wrapper as clearly shown in Figure 2. The end of the hair strand is initially inserted between the flannel sheets 3%, 35 as shown in Figure 2, and the wrapper is then rolled over and inwardly toward the pad 32. This forms a compact hair roll or curl which is secured in place close to the pad 32 by bending the free ends of the wire 36 over the sides of the roll, as shown in Figure 3.

Before applying the heating means, the roll is preferably covered by a suitable envelope or pro-v tecting means, herein consisting of a sheet of flannel or similar material 3i with a superimposed sheet ofioil, 38 as shown in Figures? and 3. The heating clamp H3 is then secured over and along the roll and its envelope, the jaws being held against the oppositesides thereof I under tension of the spring 23. ready for the application of the heating element H which is preferably heated before application to the clamp.

In practice, several such hair rolls may be made up at one time, with individual clamps it applied thereto, so that a single heating element can be applied successively thereto.

' The heating element it isinserted endwise in the socket 21 of the clamp until its extreme end reaches the end stop 28 in said clamp. Since the clamp is cool at this time, it can readily be held by the fingers while the heating element is being inserted. The heat from said element is then conducted through the metal-to-metal contact with the surrounding parts of the clamp, and particularly the plates 2 and 25, to the two jaws l3 and It of the clamp, so that the heat is distributed around the top and sides of the roll of hair for such time as is necessary to complete the hair waving operation.

It will be understood that it is highly desirable that the clamp be maintained in comparatively stable position relative to the head while'the heating element is inserted in the clamp, so that the clamp can not become accidentally displaced or twisted while in its highly heated condition so as 'to come in contact with the scalp or permit escaping steam to scald the user. With my im- The device is then.

proved apparatus, the user holds the heating element by its handle l2 so that the clamp will be maintained in its proper position during the entire heating period. It will also be observed from Figure 1 that the handle and the heatin element are together suificiently long so that the user can steady her arm on a suitable rest, and thus will not become fatigued during the several minute heating period which is required for each roll.

In the modified form of device shown in Figure '7, the heating element ll in clamp lli are of substantially the same form described in connection with the preceding figures, excepting that the heating element ll is rigidly secured to the clamp Hi as by base plate 46 and rivets 4|, 4|. The apparatus is constructed and used in much the same manner as described in connection with the previous figures, excepting, of course, that the clamp may be applied to the hair roll in heated condition. v

Although I have shown and described certain embodiments of my invention, it will be understood that I do not wish to be limited to the exact construction shown and described, but that various changes and modifications may be made without departing from the spirit and scope of my invention as defined in the appended claims.
