At the side of the casing H opposite the clamping lips thereof, the jaw sections 20 of the frame are each formed with a projecting grip member 2|, which are located substantially midway between the opposite ends of the jaw sections. Substantially at the junction between the grip members 2| and the jaw sections 20, the latter are formed with inturned complemental hinge lugs 22 which are hinged together to articulately connect the jaws so that the latter may be relatively moved.

The side edges of the jaws opposite the hinge connection therebetween are curved inwardly and are detachably united with the clamping lips la and lb of the casing II. From the drawing it will be noticed that at the edges of these clamping lips they are longitudinally grooved to receive the inturned edges of the jaw sections 20, and complemental connecting means are formed on these inturned edges and in the grooves to form a detachable connection between the lips and jaw sections. This connection is such that when the jaw sections are relatively moved, the clamping lips of the casing will be moved in unison therewith. Consequently, by moving the two grip members 2| toward each other, the clamping lips of the casing will be spread apart suiiiciently to enable the casing to be positioned over a curler.

Spring means 23 is provided between the grip members 2| which normally tends to maintain the clamping lips of the casing in clamping relation through the medium, of course, of the rigid jaw sections 20.

At the outer side of each jaw section 20 I provide a spacer clamp member 24 formed of sheet material of suitable qualities, which spacer clamp members lie closely adjacent to the outer surfaces of the jaws 20 and which extend outwardly a spaced distance from the inturned edges of the jaw members 20. At this point the spacer clamp members are inturned to provide clamping edges 25 which are arranged parallel to and at a spaced distance outwardly from the clamping lips of the casing II. It will be noticed that the clamping edges 25 of the spacer clamp members are provided with detachable rubber covers as illustrated.

The spacer clamp members are slightly resilient so that the clamping lips Ma and I8!) of the casing I I and the spacer clamping edges 25 will both tightly grip a strand of hair regardless of whether the thickness of the strand of hair is greater at the point where it is gripped by the spacer clamp than at the point where it is gripped by the clamping lips of the casing H.

For use in connection with this heater unit I provide a curler spindle 26 most clearly illustrated in Fig. 4. This curler spindle-has a curling surface which is a hyperboloid of revolution with its larger diameter at its ends. At each extremity the curler spindle 26 is formed with an enlarged circular head 21, between which heads and the curling surface the spindle is formed with bearing pins 28 which are reduced in diameter relative to the end of the adjacent curling surface. The

diameter of these bearing pins 28 is just slightly greater than the circular openings l1 formed in the end walls of the casing, so that when the casing H is arranged over the curler, the edges of the circular openings I! will register with the bearing pins 28 and yieldably grip them so as to maintain the curler concentrical y Within the curling chamber and prevent the curler from rotating. It should be stated that this yieldable gripping action between the edges of the openings I l and the bearing pins 28 enables the curler. to be turned by manually gripping one end thereon to take up any slack in the hair after the curler has been positioned and gripped within the casing ll.

Pivoted at one end to the curling surface of the spindle 26 is a clamping tongue 29 arranged to lie closely adjacent to the curling surface of the curler spindle to enable the end of a strand of hair to be clamped to the spindle at the beginning of the winding operation.

I contemplate using heat generated electrically or by chemical reaction within the heating unit to effect the permanency of the wave, both methods being commonly used 'at the present time in this art. In utilizing heat generated electrically, the curler spindle 26 is formed interiorly with an electrical heating element, which element is fitted with two contact tongues 30 projecting from one end thereof as illustrated for detachable connection with a socket connected by a conductor cord to a source of electrical supply.

When it is intended to use heat generated by chemical reaction, I employ apparatus such as described and claimed in a companion application entitled Method and apparatus for hair waving, filed May 16, 1936, bearing Ser. No. 80,128.

When I generate heat within the casing l l electrically, an absorbent cartridge 32 is dipped in the same solution that the hair is treated with and placed in the heating chamber of the casing II. The heat generated in the casing, due to the electrical heating element in the curler, vaporizes the solution, creating the hot vapors essential to give permanency to the wave. The absorbent cartridge may be of any suitable absorbent material.

In operation of my apparatus, it is constructed substantially as illustrated and described. The hair is treated with the proper solution, the strength of which determines the tightness of the wave. The hair is then divided into strands and each strand is wound on a curler 25 from its outer end to the scalp. A heating unit is then applied over the curler with the circular openings l1 receiving the bearing pins 28 and securing the curler with the hair wound thereon concentrically within the curling chamber of the casing H. In the event that electrically generated heat is to be utilized, a cartridge soaked in the same solution that the hair was treated with would first be inserted into the heating chamber of the casing.

It is obvious that as soon as the heating unit is applied to the curler that the strand will be tightly clamped just beneath the curler by the clamping lips of the casing l i urged toward each other by the spring-pressed jaws comprising the frame of the unit. Likewise, the spacer clamping edges 25 will tightly grip the strand closely adjacent to the scalp, maintaining a spacing between the scalp and the clamping lips of the casing. This provides a double seal to prevent any escaping hot vapors from contacting. the scalp.

It is obvious that due to the provision of these clamping devices formed as an integral part of the heater unit, that the operations of previously applying protector clamps and pads has been eliminated,thus eflecting a considerable saving of the operator's time- Likewise, by eliminating the use'of protector clamps and pads, the strands of hair are not bunched at the scalp so that the wave will be spaced a uniformly close distance to the scalp, thus giving a more natural appearance and effect.

It should also be pointed out that my heating unit with its clamping mediums will be considerably lighter in weight than the combined weights of prior heaters, clamps and protector pads. consequently lessening the discomflture of the permanent waving operations.

After the heating unit has been applied to the curler as previously described, the curler may be slightly turned by manually gripping one of the heads thereon to take up any slack on the hair wound thereon. The yielding gripping action between the edges of the openings I1 and the bearing pins 28 on the curlers will maintain the curler in a set position.

In the event that the heat within the casing is to be generated electrically, the curler is connected with a source of electricity as previously described and maintained for a sufllcient period of time to give permanency to the curl. The supply of fluid within the casing H, which is greater than now utilized, maintains an even steaming temperature and results in a superior wave.

After the hair has been properly steamed, to remove the heating unit it is only necessary to grip the grip members and spread the jaw members of the frame and remove the unit from the curler. The curler is then unwound and detached from the hair and the wave is ready for setting.

Here also an operation is saved in that the operator need not remove any clamps or protectors from the head, consequently expediting the entire operation of giving a "permanent wave to a head of hair.

From the foregoing it is obvious that I have provided an improved and highly efllcient apparatus for use in practicing the Croquignole method of "permanent" waving, by which apparatus I am enabled to produce a superior form of wave. Likewise, it is apparent that my improved apparatus overcomes the shortcomings of prior apparatus heretofore employed in that it reduces and simplifies the operations required to effect such a wave and therefore minimizes the time required to wave a head of hair.

Further, I desire to point out that by the use of my apparatus, a greater number of curlers may be applied to a given head of hair than could be applied by use of prior methods and apparatus so that the wave which I produce will be closely and uniformly spaced from the scalp.

Further, by use of my apparatus the weight on the head is less than the weight applied by prior methods, and consequently minimizes the discomfort of the permanent" waving operations.

While I have shown the preferred form of my apparatus, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention, as defined in the appended claims.
