16 Claims.

This invention relates generally to improvements in apparatus for waving hair and more particularly to the apparatus for waving hair by the croquignole method.

In the croquignole method the patients hair is separated in broad flat strands, anointed with suitable lotion and wound tightly around a curler mandrel or spindle. The hair is then clasped by a hinged clamp which supports the mandrel.

In the case of the steam process a hinged box, provided with steam connections, encloses the hair wound on the mandrel and sometimes a portion of the hinge clamp and steam is then admitted to the box.

In the apparatus now in common use with the electric process the hair is similarly chemically treated and as it is wound around the mandrel a felt strip is wound therearound extending contiguous with the hair so as to absorb the vapors or condensate during the heating of the hair,

preventing the same from passing to the patients scalp. The hair is then clamped by a hinge clamp and enclosed by electric heating coils which are carried by the jaws of a clip that extends down around the hair on the mandrel and engages the clamp.

It will be noted that both of these processes employ apparatus for enclosing the hair which is parted or opens at the bottom thereof or adjacent the patients scalp. The hinged hair clamp is similar in both processes and it is usually provided with rubber linededges to seal the hair where it extends therethrough. However, there is no provision for tightly sealing the exterior shell that encloses the hair and a portion or all of the clamp. The abutting edges of these hinged boxes or clips are usually provided with rubber or other resilient material but such an arrangement does not provide a positive mode to prevent vapors or hot condensate from contact with the patients scalp.

One object of this invention is to provide a new and improved means for clamping the hair adjacent the roots and preventing access to the scalp of steam condensate or other fluid which would tend to burn or scorch the scalp during the process of curling hair by either the steam or electric process.

For this purpose we provide a novel form of unitary scalp protector which is preferably formed of rubber or similar flexible waterproof material and which comprises a relative broadly extended base which fits against the scalp, and which is further provided with a longitudinally 55 and upwardly extended neck having an elongated or slotted throat through which the hair strand is led, a clamp being applied to the exterior walls of said neck to press the same inwardly and tightly clamp and seal the hair. This protector will not permit the escape of any vapors or condensate around the clamp or through exterior shell or enclosure or through the throat to discharge against the scalp of the patient.

Our invention further provides for a novel hair clamping mechanism that we provide for use in combination with the scalp protector for sealing the hair as it extends through the throat of the latter. The clamping mechanism disclosed herein provides for a uniform clamping pressure on the hair throughout the width of the strand. This cannot be accomplished by the ordinary hinge clamp which produces an ununiform pressure on the hair because of its construction as the hinge clamp of the old art tends to permit the vapors or condensate to leak between the rubber jaws to the patients scalp because of the non-uniformity of the clamping pressure.

This invention further provides a new means for supporting and preventing the unwinding of the strand of hair on the mandrel after it has been adjusted in position on the clamp support.

To enclose our improved apparatus we provide a box-like enclosure which is placed down over the strand of hair wound on the mandrel and which bears against the protector. The protector is preferably provided with an upwardly extending perimetral flange or wall within which the lower edge of the enclosure member is stepped.

Means are provided for the admission of steam and to the draining away of condensate from the enclosure at a point or points adjacent the base of the protector, the same means or tube being preferably for both purposes Other objects and means to effect the same will appear from the following description.

Referring first to Figs. 1 to '7 inclusive, 8 represents the scalp protector which is preferably made of soft rubber or similar material capable of withstanding a considerable amount of heat without endangering its elastic gripping qualities. The protector comprises the base 2 having the integral upstanding perimetral flange or wall 3 forming therewith an open box-like structure. The base 2 is provided with an integral and upwardly extending wall 4 forming a neck portion having an elongated or slotted throat or passage 5, centered longitudinally with the base 2 and through which a fiat or ribbonlike strand of the patients hair extends, the protector being pressed down against the scalp. The neck 4 with its throat 5 preferably extends up into the box protector for about one-half or three-quarters of the heighth of the wall. The upper mouth of the throat 5 is thus spaced a considerable distance from the base 2.

The long narrow heavy walled neck and throat containing the hair is arranged to permit the latter to be uniformly distributed so that when clamped the rubber produces a tight seal on the hair, preventing any vapor, steam or condensate from reaching the patients scalp through the neck.

The under side of the protector is provided with the facing 6 of felt or similar material to further insulate the scalp from heat. Such facing may be a separate mat if desired. The felt pad 6 is provided with the slot 1 which registers with the lower end of the throat 5.

One of the sides of the wall 3 of the protector is pierced adjacent the base 2 to provide for the installation of the hose connection 8 having its inner end flanged as at 9 and being exteriorly threaded to receive the nut ID for clamping the wall between said nut and the flange to hold the connector in place and to seal the edge of the aperture in the wall of the protector. The flange 9 is cut away at the bottom thereof to provide for a minimum distance between the bore of the hose connection 8 and the base 2.

The wall 3 of the protector may be provided with a tubular spout integral therewith as a substitute of the hose connector 8, but the arrangement described is preferable because of ease of manufacture.

The outer portion of the connector 8 is tapered and provided with the pin ll so that the hosesleeve l2 may be mounted on the connector 8 by a bayonet lock. The hose or tube !3 is attached to the sleeve l2. The hose connector 8 and the complementary sleeve [2 enable the operator to readily connect the steam hose line to and disconnect it from the curling chamber.

The steam or vapor generator with the controls of the individual steam lines are well known in the art and are therefore not shown.

Referring specifically to Figs. 1, 2, 4 and 6, l4 represents our novel hair clamping device comprising a pair of coacting lipped jaw members l5 whose angular ends are extended upwardly to form the levers l6, which levers are pivoted adjacent their lower ends to the opposite ends of the bridge members IS. The upper end of the levers I 6 of one of the jaw members l5 have pivoted thereto one end of the toggle levers l9-- 20, the outer end of the lever portions being notched as at 2| to engage the necks of the headed pins 22 mounted on the upper end of the opposed levers l6.

It is obvious that the portions of the levers I6 above their pivot points I! are the longer and that the length of the toggle levers l9-20 when extended, as shown in Fig. 6 is such, so that when the notches 2| are in engagement with the pins 22 and the togglelevers are forced downwardly slightly past their dead centers the jaws l5 Will clamp the neck 4 adjacent its base with such force as to prevent relative movement of the strand of hair and the neck 4 and also eifectually seal the strand of hair in the throat 5, preventing the travel of steam or condensate down said throat to the scalp. It is evident that when the toggle levers are forced downwardly past their dead centers they will be automatically locked against accidental upward movement which would contract the jaws. 23 represents a finger piece for conveniently operating the said toggle levers.

24 represents helical springs connecting the jaws l5 together at their ends and tending to urge them toward each other. As will hereinafter appear the flat strand of hair is previously wound on a mandrel before the jaws are tightly clamped on the neck 4 by the application of the toggle levers, and the springs 24 act to hold the jaws in place against the neck 4 while the winding up of the strand of hair is being accomplished and the mandrel is mounted in position.

Referring now to Fig. 5, 25 represents the mandrel upon which the ribbon-like strand of hair is wound. The mandrel is circular in cross section and preferably tapers in diameter toward its center. It is provided with the complementary shaped clamp 26 Which is used to hold the outer end of the hair on the mandrel preparatory to the winding operation.

The ends of the mandrel are provided with the annular grooves 21 Whose walls converge inwardly to engage the double beveled edges 29 of the upwardly open flaring notches 39 formed in the centers of the bridge members IS. The edges of said notches are beveled at either side so as to wedge into the annular grooves 23'.

After the end of the lock of hair is secured to the mandrel 25 by the clamp 23, the mandrel is rotated to wind the hair in a flat roll, and as the mandrel moves toward the head the annular grooves 2'! move down into the notches until they become wedged therein. As these grooves 21 and the beveled edges 29 wear with use the mandrel will come to rest lower in the slots which are deep enough to compensate for such wear.

After the hair has been wound on the mandrel and the latter has been seated on the bridge member, the toggle levers l9-20 are engaged with the pins 22 and the toggle levers are forced downwardly past their dead center until they Cal rest upon the outer ends of the mandrel which prevent their further depression.

The extremities of the mandrel are preferably knurled as at 3| to facilitate the handling of the mandrel.

The mandrel is provided with a non-round or hexagonal bore to insure a substantially uniform heat throughout the layers of the wound hair, and a key may be, inserted into the end of the bore, after the mandrel has been mounted on the bridge members, to rotate the mandrel and thus tighten the hair on the same. This is done after the jaws I5 are clamped tightly on the neck 4 and thus there will be no pull on the roots of the hair.

32 represents the enclosure or box, which may be made of light material, such as aluminum, and which has an open bottom with straight edges so that it may be downwardly inserted in place with a snug fit within the continuous wall 3 of the protector l, the said box being notched as at 35 to provide clearance for the flange 9 of the hose connection 8. The resilient wall 3 snugly grips the box to hold and seal it in place. The top of the box is provided with one or more vents 33 to provide a sufficient escape of vapor or steam to produce the necessary circulation.

To permit the same box to be used in connection with protectors having hose connections at various locations, the bottom edge of the box may be provided with a plurality of notches 35 in various portions as may be found necessary.

After the wound and enclosed strand of hair has been treated, as by steam, for the desired period the heating agent is shut off, the box 32 removed, the toggle levers Iiielevated and released from the pins 22, and the mandrel is rotated in the reverse direction to unwind the hair and simultaneously lift it from its place until the lock of hair is unwound from the mandrel and its ends released from the clamp 26. The jaws l5 are then spread apart and raised until they clear the lock of hair, and the protector I is then raised over the lock of hair to release the latter.

In curling a lock of hair in any portion of the head a protector is selected which has its hose connection in such position that it will be at the lowest point so that the condensates will drain by gravity back through the hose.

In Fig. 8 we show a modified form of the protector indicated at 31 which is unprovided with the perimetral walls 3 having simply a fiat base 38 which may be provided with a downwardly beveled edge. The protector is provided with the elongated neck 39 and the slotted throat 49 as in the case of the protector I pre viously described. This form of protector is particularly designed for use in apparatus now in common service wherein either electricity or steam is used for providing the heat.

In Figs. 9 to 11, inclusive, we illustrate the use of the protector 31 in combination with the form of hinged clamp disclosed in letters patent to Davis No. 1,820,783. 42 represents twin clamping arms hinged together at one end as at 43 and having means to close together their other ends comprising cam lever 44 carried by the locking bar 45. The ends of the clamps are provided with the stands or brackets 46 having upwardly opening notches to receive the ends of the mandrel 48, the mandrel and one of the brackets being provided with a ratchet and pawl mechanism 49 to prevent accidental reverse rotation of the mandrel. A box 50 formed of two parts hinged together at 5| and having complementary floor members 5-2 arranged to close beneath the protector 31 is used to inclose the apparatus.

Thus our improved scalp protector may be employed with great advantage not only in combination with our improved hair waving apparatus first above described, but also with the various types of apparatus now in use for the waving of human hair.

The improved hair waving apparatus above described is convenient to use and may be expeditiouisly applied and removed. No steam, condensate or fluid of any kind can come in contact with the head and any condensation or fluid which accumulates in the base i is drained back through the tube. If desired the heating agent may be electricity instead of steam.
