F LONDON, ENGLAND APPARATUS FOB PERKANENTLY WAVIN'G THE HAIR Original lo. 1,504,988, dated August 18, 1984, Berlatlo. 555,780, led April 80, 1988. Application for reillue Illed August 1B, 1988. Serial No. 689,380.

This invention relates to electrically heated apparatus for permanently waving the hair, and is an improvement in apparatus'of the tiyl'pe comprising a curler or former u on- 5 whic the hair is tlghtly coiled, and a tu ul-ar electric heater consisting of a tube on which the electric heating wire is wound and an outer enclosing sleeve or casing. In the ractice of the art of hair waving, it has en found advantageous to be able to regulate the heat applied to the coiled tress or portion of hair on the curler, in order to obtain the greatest heating eifectnear the roots of the hair and avoid excessive heating, more especially at the outer end of the tress where the hair is naturally thinner and more liable to injury from overheating.

Now according to this invention, the tubular electric heating element is formed preferably adjacent that end which in use is more p remote from the roots of the hair, with vent holes, or cooling a ertures, or slots capable of being regulated by a rotary or adjustable sleeve or shutter to allow some of the moist heat or steam to esca e, the vented part of .the element being pre erably of larger diameter internally than the non-vented part upon which the insulated heating wire is wound. In the accompanying sheet of illustrative 3 drawings: 1

Fig. 1 is an elevation of an electric heater constructed according-.to this invention,

Fig. 2 is a transverse section of the same taken at 2 2 Fig. 1.

Fi 3 is a longitudinal section taken at B-Big. 2, and

Fig. 4 is an inverted plan with a part removed.

As shown the tubular heating element conn sists of anl inner tube a which is made of brass or other suitable material and fixed to a flanged metal ring b at-one end, to which an annular end piece c of insulating material is attached. Parts of the tube a are cut away vas shown at d or the tube may be perforated with annular rows of holes while the heating wire coil is applied at e to an uncut or imperforate part of the tube of smaller diameter remote from the handle. An annular space is formed in the part c for the reception of a switch, and is closed by a cover ring or plate c'.

0ver the inner tube a and heating coil is placed an aluminium tube or sleeve which is contracted at one end 'and forme series of helical slots. g, the youter tube or sleeve f bein fixed to the flan e of the ring b.

Between t e slotted parts o the outer tube f and the inner' tube a Va slotted shutter or sleeve l1 is interposed, which is capable of being partially rotated by a handle I to open or close the vent apertures or slots g or regulate them as required. It will be understood that the vent apertures gare not necessarily in the form of slots and that they may take other convenient shapes.

In thepermanent hair waving process to l which the invention is applicable, the -tress of hair when coiled on the curler is wrap ed 1n a cloth or flannel strip moistened wit a lsuitable solution, and over which a cardboard tube is placed. The whole is then inserted in the tubular heating element, the venting of which can be regulated as describe by manipulating the movable sleeve or shutter. aThe connections to the heating coilare led through the annular end piece c and through insulating tubes j, aswitchk being interposed to open and close the circuit. l
