My improved steaming tube proper comprises an outer cylindrical tube of circular cross-section and. an inner. tube 9; co-axial therewith and fitting the outer tube so as to be rotatable therein on. a common axis therewith. The inner tube may also be moved.

pose to be described.

The outer tube 1 has a wide longitudinal slot 3 in its. periphery and the inner tube 2 has a corresponding slot 4 registerable therewith. See Figs. 7' to 9 inclusive. When the inner tube 2 is rotated 1.80 the body portion of each tube will close the slot. of the other making a transversely continuous enclosing steaming tube.

lhe scalp end ot the outer tube 1 isclosed, as shown in Figs. 1, 9 and 10 by an end wall 5 and the inner tube is similarly closed by an end wall 6, the two walls 5 and 6 having generally V-shaped notches 10' and 11 respectively therein opening outwardly into the wide slots- 3 and 4. The notch 10 in the end wall5, see Figs. 9 and 10, has a portion 7 at the center of the head of circular curvature and thence the edge of the notch 10 proceeds outwardly as at 8, tangentially to the portion 7, at one side thereof, and at the other sidethereof, the edge 9. extends from the portion 7 according; to aconcave curve, which. may be of circular or other profile for a camming; purposeto be described. The notchlll is of similar profile tothe notch 10, but reverse 1 as three, legs 17, as shown in Fig. 1.

with respect thereto as shown in Fig. 9, i. e. when the two notches are registered as in Fig. 9, the concave edge 12 of the notch 11 is opposite to the concave edge 9 of the notch 10.

When the inner tube is rotated within the outer tube in the counter-clockwise direction, as viewed in Figs. 9 and 10, the concave camming edge 12 of the inner tube cooperates with the concave camming edge 9 of the outer tube to embrace therebetween a lock of hair to be waved, in a manner to be more fully described later; and the two concave edges enclose upon the hair and the camming edges throw the lock toward the center of the two heads 5 and 6 and finally compact and grip it in the circular aperture 13, Fig. 10, formed by the circular portions 7 of the notches 10 and'll in the overlapping heads 5 and 6.

In practice, as will be described, and as shown in Fig. 1, a wrapping material is first wrapped around the hair so that the edges 7 of the heads in practice preferably clamp or grip the wrappingwith the hair inside thereof. From this description, it will be seen that the two heads 5 and 6 and their V-shaped notches cooperate to provide an opening and closing aperture 13 of the iris type.

' Also, at the scalp end of the tube, I provide a shield, preferably formed of material having relatively low specific heat capacity, such as fibre, bakelite or the like. The shield comprises two disk- shaped elements 14 and 15 pivoted together by an eyelet, as at 16. The disk 14 has on its inner face a plurality, such Rivets or pins 18 are preferably embedded centrally in the legs and inwardly project through apertures in the head 5 and are riveted over therein as at 19. By this construction the disk 14 is secured to the end of the outer tube, but is spaced therefrom, providing an air space 20 by which the end of the tubes are heat insulated from the shield. The shield is thus kept at a low temperature and burning of the scalp is prevented. The disk elements 14 and 15 are each provided with generally V-shaped notches 21 and 22, and when the disk 15 is rocked around the pivot 16 from the position shown in Figs. 2 and 5, to the posit-ions shown in Figs. 3 and 6, the notches 21 and 22 enclose, iris fashion, a generally circular aperture 23. As will be more fully clescribed in connection with Fig. 1, the aperture embraces with a clamping action the wrapper and the hair within the same.

In the operation of my improved steaming tube, thus far described, a lock of hair 24 to be waved is first wrapped under tension or stretch upon a rod 25, which may be of the usual pattern, being secured thereto by a slots and end wall notches, above described, with the end 28 of the wrapper projecting through the notches 10 and 11 and through the notch 21 of the shield, the position thereof being generally as shown in Fig. 1.

The shield is then closed up by locking the disk 15, as described, causing it to close upon and grip and seal the end of the Wrapper 28 on the hair 24, as in Fig. 1. The inner tube 2 is then rotated by means to be described within the outer tube 1, closing up the tube longitudinally and causing the notches 10 and 11 to enclose and grip the hair 24 and wrapper 28, as in Fig. 1, and thus also sealing the end of the tube.

To support the rod and its hair andwrapper axially in the tube, the outer end of the rod 30, Fig. 1, is supported in a clip 32 provided for the purpose and shown best in Fig. 7. The clip 32 may be made of fiat resilient material and generally of W-shape, the free ends being secured to the inner wall of the inner tube 2. At the axis of the tube the clip has a partially closed circular grip portion 33 to receive the end of the rod. The rod may be lodged therein by pressing the end thereinto.

The heater 35, which may be of any known or suitable type, is applied to the tube by slipping telescopingly over the free end of the tube into the position shown in Fig. 1. To hold the heater on the tube, the outer tube 1 is provided with a spring clip, or clips 36, which in the preferred form shown are made of thin flat resilient material and riveted as at 37 to the wall of the outer tube 1. The clips 36 have outwardly convex portions and engage the inner bore 38 of the heater as shown for one of the clips 36 in Fig. 1. The frictional engagement of the spring clip with the heater thus retains the heater on the tube against longitudinal displacement. It will be understood that one clip 36 may in some cases be sufficient, but two or three, if pre ferred, may be employed.

In order that the wrapping 28 may be securely gripped in the shield and in the heads 5 and 6, as above described, it is desirable that the inner end thereof indicated at 39,

Fig. 1, be substantially at right angles to the axis of the tube. To this end, I employ, preferably, a wrapper, illustrated in Figs. 11, 12 and 13. The material of the wrapper may be of any suitable material, but I prefer to use flannel. The wrapper is formed in a narrow strip, for example one and a half inches wide by five inches long, one end of which is cut 01f as at 42, Fig. 11, at an angle of about In the opposite end a wire 44 of suitable material such as fuse wire is threaded into one edge of the wrapper for a purpose to be described. In wrapping the wrapper around the hair on the rod, as hereinbefore referred to, the wrapping operation proceeds as illustrated in Fig. 12, the axis 41 of the convolu- .inner tube 2 and made preferably tions being approximately at. a right angleto When, thewrappmg operationis substantially complete the edge 42 as shown in. Fig. 12.

as shown in Fig-.13., the last turn or two of the free end 43 of the wrapper will wrap or windthe wire 44 on the underlying eonvohu tions and bind the end. of the" wrapping to prevent the wrapping from unwinding. With a wrapper of this kind, wound in the manner described, the. end- 39 of the wrapper will be in substantially one plane and at a right angle to. the axis of the wrapper, for the purpose referred to above.

The construction by which the end of the tube oppositethescalpis sealedand by which the inner tube 2 is rotated within the outer tube will now be described. The said end of the inner tube 2 is provided with a circular disk or head 45 sealed to the wall of the of material thicker than the adjacent walls of the tube to provide a suitable base for asupporting handle and clutch device for the inner tube, to be described. With this contube is turned on struction, when the inner as a: whole, is

itsaxis, the end of the tube, sealed.

Mounted uponand projecting axially outwardly from the head 45- is a flat handle 46 adapted to be grasped between the thumb and finger. By giving it a twisting motionthe inner tube may be rotated. In some cases, it may be possible to bring the V-shaped notches 10 and 11 in the end walls 5 and 6 at the opposite ends of the tube, into exact opposition and therefore the compression of these notches upon the lock of hair and its covering may react to rotate the inner tube backwards or in the clockwise position, Fig. 10. To prevent this, a clutch device is provided. The clutch device may be of any suit able form, but in the preferred form shown,

in the drawing, it consists of a clutch element 47 composed of a piece of flat resilient material, extending radially through an aperture in a lug 48 secured to the head 45 and extending outwardly axially therefrom. The outer end of the clutch element 47 abuts upon the inner wall of the outer tube 1, as shown at 49in Figs. 2 and 4 and at an angle therewith,

the angle being in such direction that when the lug 48 is moved by rotation of the inner tube in the clockwise direction, as viewed in Fig. 4, the end of the clutch element 47 will trail along upon the inner surface of the tube 1.

As will be apparent, if the inner tube tends, as above described, to rotate in the counter-clockwise direction, as viewed in Fig. 4, the end of the clutch element will frictionally engage or bite into the wall of the outer tube at 49 and prevent such rotation. The clutch element 47 is preferably curved, as shown in Fig. 4 and to support its other end and to adapt it to be slightly withdrawn hr ugh he aperture in the lug-48 to free; the clutch, in order that the tube may be rotated in the reverse direction, the said: end of the clutch element 47 is pivotally connected as atv 149 to the free end of a lever 50' pivoted at 5i to a post 52 on the handle 46. The lever O extends beyond the pivot 51 and is suitably formed for a handle 53 adjacent the handle 46 and spring pressed away from the handle 46 by a fiat spring 54 rivetedto the handle at 55 and pressing against the handle 46. Thus, the spring 54 tends to hold; the

lever 50 in a counter-clockwise position, as

viewed in Fig. 3 and this communicates outward radial movement to the clutch element 47. When it is desired to release the clutch, the tube handle 46 and the lever handle 53 may be pinched together between the thumb and finger, thus rocking the lever and withdrawing the clutch element 47 out of en' gagement with the wall of the tube 1. While the handles 53 and 46 are thus pinched together, a twisting movement may be given to them which will be communicated to the inner tube 2 and rotate it on its axis, as above described. I

- To prevent the inner tube fromv accidentally being removed from the outer tube, in a Iongitudinal direction, any suitable means may be employed. In theconstruction shown, a small screw or screws, one of which is shown. at 56, may be screwed through the outer tube 1, adjacent to the outer-surface; or face f the end wall 45 of the inner tube. Longitudi-nalmovement of the inner tube will thus be stopped on the screw 56. On the other hand, the screw 56 may easil be removedwhen it is desired to withdraw the inner tube 2 from the outer tube 1 for cleaning or disinfecting purposes.

I find that the outer and inner tubes: 1 and 2; and the heads and other parts thereof may advantageously be formedfrom sheet, metal such as aluminum, but it will be understood that other material such as especially 11 36- pared fibre, paper composition, asbestos composit-ion, bakelite, castings, etc, be em.- ployed.

I have shown and'described my invention as used with a pad 27 wrapped around the hair, but my invention may be used in mail-ycases with equai efhciency' without the pad. In this case, the compression ofthe hair by direct contact with the notches in the end walls of the tube may be relied upon to seal the tube. In such cases also, when moisture solution, as

dicated in the drawing at trated and described,

axial therewith and each end wall inner tube, an

moistened with a solution of the kind well known in the hair waving art.

When it is not desired to entirely wrap the hair with" the pad, the sealing advantages of my improved pad may be had by employing a relatively short pad of the length inclicated by the broken line of Fig. 11. Such a pad may be employed with or without the may be desired.

In some cases, to properly vent my improved steaming tube, I find it desirable to provide a vent hole in the inner tube and preferably in the outer head thereof, as in- Having thus described my invention, in a preferred embodiment I am aware that numerous and extensive departures may be made from the embodiment herein illusfrom the spirit of my invention.
