ELECTRIC HAIR CURLER.

Application filed December 23, 1926. Serial No. 156,585.

l ly-invention relates to the art of making permanent waves in hair and has special reference to the methods employed where electric heat is used and where the hair is on the head. In all of the permanent wave heaters, with which I am familiar, there is a fixed size of heating container for the hair and this has been found in practice to be inadequate to take care of the widely differio ent sizes of curls that have to be made with the same device. In order to overcome this objection, I have invented an electric heater which is adaptable in its size to the work to be done; that is to say, if a large curl is to i be formed, the heater is elongated to fit, and vice versa, as will be hereinafter explained.

Referring to the drawings, Fig. 1 is a side view partly in section of the preferred form of my heater; Fig. 2 is a modified form of the same; Fig. 3 is an end view of Fig. 1 looking from the top; Fig. 4 is an end view of Fig. 2 looking from the top; Fig. 5 is an end view of Fig. 1 looking up from the bottom; and Fig. 6 is an end view of Fig. 2 looking up from the bottom.

In Fig. 1 I have shown my heater in tubular form. The lower end of the device consists of an electric coil 4 supported in an outer shell 2, the latter forming the body of the device. The coil 4 is provided with an inner shell into which are telescoped a number of tubes 6 of slightly different diameters, one sliding within the other, so that each tube nests in its proximate tube and all of the tubes when pushed together nest in the body of the heater. In order to prevent the tubes 6 from becoming disengaged when extended, I provide their ends with shoulders which engage with each other when the heater as a whole or any two sections are drawn out to their longest dimension. On the open end of the body 2 I provide a pair of shutters 12 pivoted at one side to the end of the body 2, and at the other side they engage with a stop pin which holds them in proper position with the heater when they are closed. The shutters are provided with a concentric opening in which is replaceably inserted a sheet of elastic material, bifurcated so as to open and close with the shutters and when closed form an opening through which the hair can pass. The elastic material provides a means of self-adjustment of the opening for different sizes of strands of hair to be curled.

The opposite end of the hair curler is. provided with a similar pair of shutters 10 (only not provided with elastic center portions) shaped to form a concentric hole when closed. Passing through this hole and through the longitudinal center of the heater, I have a so-called pencil or rod 8 around which the hair is wound, and to facilitate holding the hair in place I construct the pencil at one end with a short slot. It is seen that I have hereby devised a hair curler that can be adjusted to any length, within its capacity, to suit different lengths of curls. It is also seen that as the curl becomes smaller, not only the length of the heater can be adjusted but the diameter as well, by selecting the proper size tubes to push together, and vice versa.

In Fig. 2 I have shown a modified form of heater wherein the tubes 26 are of smaller diameter near the electric heater 24 than at the outer end of the device. This construction enables me to provide a chamber on the inside of the heater into which the tubes can nest, the inner tube of the chamber constituting the first tube 26 of the series. This chamber can be shorter than the body 22 of the device so that heat can pass directly from the coils 24 to the hair and pencil 28 without passing through the intervening chamber. In this form of my invention I may provide the upper end of this chamber with a pair of shutters similar to 30 which enclose the outer end of the device.

I-Iaving described my invention so that any one skilled in the art to which it pertains can make and use the same, what I claim as my invention and cover by Letters Patent is:

An electric heater for curling hair comprising a pencil around which the hair is wound, a heater to heat the hair, and an enclosure adapted to be longitudinally adjusted to different sizes to suit the size of the curl to be formed.

2. An electric heater for curling hair comprising a pencil around which the hair is wound, a heater to heat the hair, and an enclosure adapted to be longitudinally adjusted to different sizes to suit the size of the curl to be formed consisting of a series of telescopic members adapted to be nested one within the other.

3. An electric heater for curling hair comprising a body enclosing a heating coil and a 110 series of telescopic tubes forming with the body and enclosure for the hair, adjustable as to size.

4. An electric heater for curling hair comprising a chamber to enclose the hair adapted to be adjusted as to size and a shutter at each end for retaining the heat.

5. An electric heater for curling hair comprising a chamber adapted for elongation 10 and contraction and a shutter closing the end of the chamber partly formed of resilient material.

6. An electric heater comprising a series of telescopic members, one member c0nsti-' tuting an electric heating unit into which the other members can nest.

Signed at New York in the county of New York and State of New York this 21st day of December, A. D. 1926.
