The strip 21a is provided with an angular flange In the drawing: 3!, between which and the external surface of Figure 1 is a view in front elevation of the comfi z gf d fig gag g z a 2 1 3 2 01 45 gffg i i i in end 618 th tinued into the upper ring portions 21?) of the w Ion ereo blank from which the jaw is formed and same are Figure 31s a v1ew in elevation looking toward adapted to freely lap over the ends of the the P S 1de of w apparatus; plementary jaw 112 as shown in Figure 2, whereby 50 Figure 4 1S a Section taken on h lme of to secure both jaws against relative longitudinal Flgure movement. Above said ring portions, the body Fi u 5 is a p p c v V of the complee of the blank is formed with a linear flange 33 mentary gripping elements of the laws of the which is freely received in the groove l8 of jaw I2, clamp; whereby the jaws may be hinged together to en- 55 able them to be opened and closed as and when desired. The two jaws I2 and I3 are resiliently held closed against each other by stiff loop springs 35 of flat steel, the respective free ends of which are received in the depressions 25 and 28 of the respective jaws.

A heater constructed as aforementioned is thus provided with a heating chamber 35 which is defined by the semi-cylindrical portions I and 26 of the respective jaws l2 and I3, and said chamber is adapted to receive and. completely enclose a spindle 3'! on which a strand of hair is adapted to be Wound as is customary and well known in the art.

The aforementioned heater of the invention is used in combination with the hair clamp I I, the same comprising the cooperable jaws 38 and 39. These jaws are each formed of narrow parallel strips of heat insulating material 4040 secured to the opposite sides of a metallic insert 4|. At one end of the clamp, the metallic inserts 4| are connected together by hinge strips 42, in which one thereof is provided with a bearing bracket 43 to rotatably receive the end of the spindle 31 which carries the usual ratchet wheel 44 with which the detent spring 45 is adapted to engage and thereby hold the spindle against unwinding. The opposite ends of the jaws are connected together by a latching link 45, the same having a cam 41 which coacts with the jaw 39 to secure the clamp in applied position against the hair close to the scalp.

The opposite end of the spindle 31 is rotatably received in the bearing bracket 48 on link 46.

Firmly secured between the stiff insulating materials 40 of the jaws 38 and 39 are soft rubber strips 49 between which the hair at the scalp is adapted to be resiliently gripped. These strips are formed with parallel linear flanges 50 which are sufliciently'offset from the inner face of the clamp to afford a yielding surface for direct contact with the scalp rather than allow any of the metal parts to contact the scalp. At the opposite side of the clamp, the strips 49 are formed with relatively wide flanges 5| between which the hair may be clamped and against the external surfaces of which'pressure may be brought to bear by virtue of the hard rubber strips 22 and 32 of the respective jaws'l2'and I 3 when the device is fully adjusted to the position shown in Figure 4. In order to prevent the hot vapors escaping from the chamber 36 during the process of waving the hair, use is' made of a sealing strip of soft absorbent material 52, one side of which is faced with an impervious sheet 53, such as waterproof paper, the size of which is the same as that of strip 52. The material 52 may be cotton or any other material which is soft and capable of yielding when pressure is brought thereagainst.

In operation, the hair is wound upon the spindle 31 in a manner well known to those trained in the art to which the invention relates,

it being understood that the clamp II is firmly secured to the hair and that the flanges 50 are in yielding engagement with the scalp. After the hair has been tightly wound onto the spindle and the latter held against retrograde rotation in the bearings 43 and 48, the aforementioned sealing strip is then passed around the spindle and its free ends brought into overlapping relation to the external faces of flanges 5|, the soft pliable material of the strip being disposed inwardly. The jaws l2 and 43 of the heater in are then applied as shown in Figure 4, whereby the hard rubber strips 22 and 32 will bear firmly against the outer impervious sheet 53, the soft inner strip 52 being yieldingly pressed tightly against said external surfaces of flanges 5!, whereby to prevent the escape of hot vapors from between the co-operable jaws of the heater.

The spindle 31 is of the perforated type to enable the hot vapors to pass into the outlet bore 54 of the spindle. It follows from what has been stated that the hot vapors are maintained against escaping from the chamber except by way of the bore 54, and that in consequence thereof the heat will be more effectively utilized than was possible with the devices of the prior art and that the clamp ll cannot only be more comfortably worn upon the head during treatment of the hair, but

that the scalp will be protected against being toward each other to enclose the spindle in the chamber; of a hair clamp, and a sealing element removable from the chamber and adapted to embrace the spindle and having terminal portions engaged by the members and maintained thereby in gripping engagement with those portions of the clamp between which the hair strand under treatment is interposed, whereby to prevent escape of hot vapors from between said members at said clamp.

2. A device of the class described comprising a clamp having laterally projecting confronting portions of soft pliable material between which a strand of hair can be clamped; and a heating chamber for receiving a spindle on which hair to be waved can be wound and said chamber including portions in removable gripping engagement with said confronting portions of the clamp to prevent lateral escape of hot vapors from the chamber at the clamp. a

3. A device of the class described comprising a clamp having portions between which a strand of hair can be clamped; and a heating chamber for receiving a spindle on which hair to be waved can be wound and said chamber including portions between which said laterally confronting portions of the clamp are adapted to be interposed and gripped by said heating chamber portions so as to prevent lateral escape of hot vapors from the chamber at the clamp.

4. A heater comprising a jaw having a substantially ovate portion for reception of a heating element and said portion having a linear groove at one side and said jaw being also formed with a semi-cylindrical chamber defining portions, a jaw having a semi-cylindrical chamber defining portion confronting the chamber defining portion of the first named jaw and having a flange extending into said groove to enable one jaw to tilt relative to the other; and spring means engaging the jaws to press same together to house a spindle within said chamber defining portions.

5. A heater comprising a jaw'having a substantially ovate portion for reception of a heating element and said portion having a linear groove at one side and said jaw being also formed with a semi-cylindrical chamber defining portion, a jaw having a semi-cylindrical chamber defining portion confronting the chamber defining portion of the first named jaw and having a laterally projecting confronting I flange extending into said groove to enable one jaw to tilt relative to the other; spring means engaging the jaws to press same together to house a spindle within said chamber defining portions; and each jaw including a plate having recesses receiving the ends of said springs and provided with flanges exteriorly related to said chamber defining portions; and linear strips of stiff material secured between said chamber defining portions and said flanges for gripping engagement with a hair clamp.

6. The combination, with a hair clamp having longitudinally extending yieldable jaws between the inner faces of which hair can be clamped,

of a heating chamber having longitudinally extending jaws adapted to engage the outer faces of the jaws of said hair clamp; and means of moisture-proof sheet material removably received in the chamber and within which a hair-coiling spindle can be enclosed and including longitudinal portions extending axially of the spindle and disposed exteriorly of the chamber so as to be confined by the jaws of the latter in fluid sealed engagement with the outer faces of the yieldable 10 jaws of said hair clamp.
