55 of the rod a. e 1 Two rods @may be provided of different n mean diameters for the same sheath a, so as to take into account the various thicknesses of the coiled hair.

The rods may be hollow in order to reduce the weight.

Referring to Figs. 7 to 18 showing a slight modification of the'invention, as above described the rod a has a lengthat most equal to'that of the sheath and is provided with a removable handle so as to facilitateiits manipulation and. to permit in addition the placing of aplurality of devices quite .close to one another.

The rod 0. is of tubular form and has hinged. near one oi. its extremities'a member 0 of semi-circular sect-ion and adapted to fit exactly upon the rod to, the members a." and c constituting the hair gripping clip and being made of aluminium for example.

The sheath 2, of aluminium or other appropriate metal of cylindrical form closed at one ofits extremities and having a longitudinal slot 6" similar to that described .with

reference to the first embodiment.. The

fixed to the extremity of the i'odfci'a The device described is employed inthe.

sheath is slightly fiaredat i at its open extremity to facilitate the introduction of the rod a. It is furnished near said extremity with a groove j in which is located a resilient split metal ring 70. When the gap in the ring it opposite to the slot 6 of the sheath '5 (Fig. 7), the hair may be introduced-from theside into the said slot and it is retained therein by turning the ring ll; in the groove so that thetwo gaps are no longer opposite to one another (Fig. 12).

The rod af'is of such a length that the extremity thereotlies flush with the open extremity of sheath 2 and is provided with a removable handle m, above mentioned for the proper i-nanipulation of the member a.

The extremity of said handle on is provided with a tubular cylindrical portion n, the diameter of which is slightly less'than the inner diameter of the rod a". This cylindrical portion is provided with two bayonet slots 0p. The channels 0 allow for the manipulation of the rod 72, when they are passed over the pin 9. By pushing further forward the handle m, this latter may be attached to the rod It When the pin penetrates into the channel patter partial rotation.

' The'sheath i is provided on the interior at its'closed extremity with an axially projecting portion 1" adapted to engage in the roda.

and integral with a radial pin a suitable for engagement with the teeth of a ratchet-t following manner. I 4

The handle on is introduced into the rod a by means of the bayonetoint. 0p.

, Then the jaw c is raised and the left hand end of the rod a is passed under the lock of hair which is smoothed by means ot a comb held in or three times about its own axis to coil the so that it is flat. Then the member 0' is turned down on the lock to be gripped and position. The rod a is rotated two lock thereon. Then the rod a is introduced longitudinally into the sheath 6, whilst the lock is passed through the slot e. The ring k. is in such aposition on the-sheath i as to allow for the introduction of the lock, the sheath i which has been previously heated being held in the left hand by means of a special clip. Then the rod has thus been introduced into the bottom of thesheath i, it is. rotated about its own axis by means of the handle m until it is near to the skin. It cannot roll backwards owing to the fact that the teeth 25 come one after another into engage" ment with the pin 8. Various portions of the hair are brought in succession into direct contact wit-h the said heated sheath i, so that a'good curling or waving is obtained. Lastly the device shown atFig. 13 of insulating material is 'sinterposed between the .skinand the sheath e which remains .in position momentarily, as also the rod aflthe handle on 7 being Withdrawn. The device shown at :Fig. 13 may be made of any-heat insulating material, such for, instance as fibre. The ring I", is brought into the {closing position. of the slot -e., as soon as the lock of hair has been introduced and before completeeoiling.

After this operation," a second lock is treated in the same manner with the use of a second rod a and a second sheath 2' and so forth. I

It is possible with the device described to dispose groups including a rod a and a sheath i very close to one another, this arrangement being more difficult when making use of the devices. according to .the first 5 embodiment. I
