The inner section of clainping member 5 is partitioned by means oi' a pair of spaced transverse plates 12 and 13 respectively, plate. V13 closing` the inner extremity andiny automatic switch is disposed in the compartment so toi-ined. A fixed contact pin 111 is secured to and insulated from partition 1Ql eXtending longitudinally ot member 5 and projecting into the switch compartment.- One ot' the ends ot the` heating element 10 is connected to said contact, while the other end ot the heating elementis connected to a lead wire 15. An insulated pin 16 is slidably disposed within member 5 er;i tending transversely thereof and having one end projecting through the rounded clamp- Aing edge ot' member 5. `The opposite end oit yond member 5 to be engaged by the inner n s D d u l surface of the intermediate portion. oit c1 amping member 6 retracting contact 18 from its engagen'ientwith fixed contact 11i when the lpclampingmembers are closed about a lock y.oit hair. Thus when the hair is actually being lwaved the circuit through the heating elel ment will be broken and there will be no possibility of scorching or burning the hair, although suilicient heat will be retained by the inner clamping member 5 to nicely wave the passed through the. hair to separate' and en-.

hair. As soon as handles 7 and 9LPL are pushed apart insulating pin 16 is released and the circuit is again completed through the heating clement.' The iron obviously may be testeditor temperature betere application to the hair and the inclined outer endsof the clamping members 5 and 6 may be easily gage a desired portion or lock.

In effecting a Marcel wave the iron is successively applied to a` lock ot haii', forming y with each application a complete wave. 1t

i is not necessary to reverse the position ot the iron, since a relatively long sofcalled flat wave is completed by each application. Each wave comprises an inverted U-shaped conve-X portion and short relatively straight portions extending fromthe side thereof. Vllicn the instrument is applied to the immediately adjacent portion of the vlock the adjacent relatively short straight portions are joined, co-

Y operating to torni twocomplete waves.

From the'foregoing description it will be seen that I'l'iave provided a simple but highly efficient Waving iron. Ytor hair capable ot quickly effecting ornate Marcel waves and so constructedthat scorching or burning of the hair will be impossible. The device coinprises few parts and can be nianutactured at little expense. My improved automat-ic cut oitrz switch isV posit-ivel in nature and will withstand long continuous usage.'

It will, oi' course, be understood that various changes may be made in the form, de-

tails, proportions and ar -angenient of parts current will be shut otfvthrougli said heat-y ing element when the device isactually in operation. Y

3. Hair Waving apparatus comprising a pair of pivotally -connected interfitting clamping members, an electric `heating eleincnt disposed within one of said clamping members, electrical connections adapted to connect said heating element with a source ot'electricitY and a switchldispose'd Within -one ot' said c amping members and interposed between one of said connections andone end of said heating element, said switch including a movable contact having 'an-insulated extension projecting through the face ofsaid last mentioned clamping member and adapted to be engaged by the opposite face of said other clamping member when said members are swung together.

Hair waving apparatus comprising a' pair of pivotally connected intertitting clan'iping members, an electric heating ele- `ment disposed within one'of saidclamping members, electrical connections adapted to connect said heating element Witha--source of electricity and a switch disposed within one of said clamping members and interposed .a

between one of said connections and one end ing a fixed contact and a slidable contact having an insulated extension projecting through the face of said last mentioned clamping member and adapted to be engaged by the opposite face of said other ciamping member when said members are swung together, and means for `yieldinglyholding said movable contact in engagement with said fixed Contact when said members are disposed apart. n

5. Hair waving apparatus comprising a pair of pivotally connected elongated interitting clampingmembers adapted to compress a lock of hair, one of said members havingV a relatively deep grooved face of approximately U-shaped cross section, the base portion of the U being rounded and oi a width less than two-thirds of the depth of said groove, said groove having substantially fiat parallel sides, said member also having out-turned longitudinal ianges extending from said face, said other member having a tenon portion complementary shaped to said groove and carrying out-turned flanges adapted to be pressed against the outturned ianges of said grooved member.

6. In an electrical heating apparatus o"i' the class described, a pair of co-operating clamping members adapted to be moved together to press in shape material therebetween, an electrical heating element carried by one of said members and adapted to be connected to a source of electricity, a switch carried by one of said members, means 'for holding said switch in closed position when said clamping members are disposed in spaced relation, whereby said members will be heated, and means for automatically opening said switch when said clamping members are moved together, the residual heat of said clamping members being sufficient to press and form saidmaterial.
