7 Claims, 1 e -The invention relates to improvements in'caps and more particularly to the novel construction of a hair waving cap primarily intended for use by the hair dressing profession,

Hair waving of the kind known as cold permanent waving or m'achineless waving is accomplished through a performance of a series of steps which involves first, the dividing f the hair on the head into a plurality of tresses. In cold permanent waving the individual hair tresses are wound firmly and secured upon curling rods either before or after saturating the tresses with a softening solution which is permitted to remain on the hair tress for a predetermined period of time determined by the texture of the hair being treated. Upon the expiration of such period of time a rinsing or neutralizing solution is applied to the resulting curls so as to neutralize the softening solution and set the curls. The curls then are removed from the rods. Obviously, if the curl is insufiiciently treated it will not retain its intended shape and should the softening solution remain on the wound tress for too long a period of time the hair will become hard and brittle.

In order to retain the natural heat of the head within the region of the curls while the softening solution'is acting thereon, the entire head is enclosed within a suitable covering such as a cap or hood. Owing to the impossibility of determining, with any degree of certainty, the length of time during which the solution is to remain on the curls, it is customary to test a curl after an estimated" minimum time interval. to ascertain whether or not additional treatment is required. This isaccOmplished by exposing at least one wound tressand unwinding said tress from the rod. I f further conditioning is required the tress is rewound and replaced within the cap or hood. In those instances when the entire head is enclosed within a cap of known construction it,

therefore, becomes necessary to remove said cap or at least to loosen it sufliciently to enable it to be: shifted to expose one of the wound tresses for testing; Should the cap be removed or shifted during'the'testing operation most of the heat confined therein is lost and when the cap is replaced additional estimated time is required to restore'the temperature within the cap to that re quired for further processing. It is, therefore, an object of the present invention to provide a hair waving cap with novel structural characteristics to enable access to be gained to a single wound tress for testing without uncovering the entire head or otherwisepermitting confined heat to Ch c g WW9- Another object is to provide a hair waving cap with novel means normally sea-ling the cap against the loss of confined heat but which may be easily and quickly displaced so as to expose one or more wound tresses for testing, A 7 v Another object is'to provide a hair waving cap embodying the novel structural features of the present invention which is not expensive to manufacture but which is very easy to use and highly practical and eflicient in use;

Other and further objects of the present inven tion will be apparent" from the following -description and claims and are illustrated in the accompanying drawing which shoWS. a preferred embodiment and the principle thereof and which is considered to be the best mode contemplated for applying that principle. Other embodiments of the invention embodying the same or equiva lent principle may be used and structural changes may be made as desired by those skilled in the art without departing from the spirit of thepresent invention and the purview of the appended claims. 1'

' Fi 5 is a view on a'reducedifs'cale of "one of the two'pieces of sheet material forming the body ofthecap.

'Fig. 6 is a view similar'to Fig. 5 showingxthe' other piece of sheet material.

The hair waving'cap dis'closed'in the acco'mpanying drawing is of a kind that will'completely' cover the head of'the wearer. leaving the'face' only exposed and it is fashioned from two out pieces of sheet material such as, for 'example; a tough transparent'or translucent flexible non-=- side of the crinkly slightly elastic sheet of material imper vious to the chemicals and heat us'ed" intheproc ess'es of "cold permanent waving." It should bev understood, however, that other sheet material, suitable for manufacture-into capsl ofithe kind disclosed herein, "maybe used without departing from the purpose of'th'e present invention; The'cap i's fashioned from two -substantially.- like-shaped' pieces of'sheet material ll -and"|2- (Figs: 5' and 6) suitably joined together along-se lected; complemental. .edg'es to: provide: a; hood; or:

cap of suificient size to completely envelope the wound hair tresses on the head of the wearer. As best illustrated in Fig. 3, the completed cap has its bottom edge, or neck-line, provided with a continuous hem I3 opening onto the edges surrounding a face opening I4 formed on the front side of the cap.. The hemmed bottom edge I3 of the cap is positioned around the. neck of the wearer. \A draw string I5, extended through the hem, is provided for drawing the bottom of the cap snugly around the neck to prevent the escape of heat confined within the cap during the hair waving.

process.

The piece of sheet material II- forming a part of the cap is best illustrated in-Fig; 6- and it is" substantially rectangular in shape havin .the

hem I3 on its straight bottom edge and suitable:

like the piece described hereinabove and is. best shown in Fig. 5. As illustrated,v the piece I2 ineludes the" hemmed bottom edge. i3 and. piping I6 on one of its side edges. The top edge- I9 or said piece of sheet material I2 preferably is left unfinished and a lateral extension or flap portion 21: is fashioned integral with and extends outwardly from the other side edge. 2-2 of. said piece. This flap or extension 2| is substantially co-extensive with the length oi the side edge 22'. but terminates short of the bottom end thereof and preferably its edges are suitably finished. with piping 23.

The pieces of sheet. material II and I2: are suitably Joined together along selected complemental edges;to'formz.thecap.- To this: end, the. piece II- is laid in faceto face contact over. the similarly shaped portion of the piece of sheet material. I2 and the complemental top edges. I8: and. I9 are joined together over their" entire length as: by means of a row of stitches. The edge portion. 22 of the piece I2 likewise is stitched or otherwise secured to the complemental portion of the edge I'I of' the piece I-I care being taken so as not to sew the hem I3 shut at the joining of the two sections inasmuch as. such blocking; on? of the hem I3 would impair the operation of the; draw string I therein. A piece-of elastic: 24- is sewn orotherwise secured to the upper medial portion of the-mar.- ginal edge-surrounding the face; opening I4 sothat the material within said portionisnormally gathcred. or otherwise. drawn: togetherin such manner that' the front edges: of. the. cap will be drawn. tightly around the face of the wearer to thereby insure a; relatively snug'fili. around the; entire-body of wound tresses confined within the cap.

has been. noted hereinabove', the customary procedure while: permanent waving hair on the human head; is: to select one of the wound tresses, afterthe waving process has continued fora predetermined period oftime, and test it. todetermine whether or not further processing: is. re'-- quired'. The cap of the. present. invention is particularlyprovided with. means. to facilitate gaining access to one such wound: tress without the necessity of loosening the cap or removing the same from all or partof" the head. Accordingly,- the greatest. portion of the edge ll of the: piece of sheet material II is left. unsecured to the companion piece of sheet material. I2. so as to leave a slotted opening 25. extending upwardly substantially vertically onthe back side of" the. cap rro'm a point closely adjacentv to the hemmed.

bottom neck portion. This opening is of a length corresponding substantially to the width of the flap or extension 2I on the companion piece of sheet material I2. During the processing of the hair, the flap 2I is tucked into the slotted opening 25 so as to lie substantially against the inside face of the piece of sheet material II; When it is desired to; gain access into the cap for thezpurpose of testing a wound tress the flap 2| is withdrawn from the slotted opening 25, as best shown in Fig. l,- thus exposing at least one of the curls for examination.

It should be evident at this time that the cap embodying the features of the present invention is constructed in a non-expensive manner from sheet material and that it may be :easily and quickly mounted. in. place over the head of the wearer; and further, that said cap embodies means whereby access to the interior thereof may be eiiected easily and quickly without disturbing the relative position of the capon. the head.

Although an exemplary form oi hair wavingrcap has been illustrated in the accompanying drawingand described in detail in the foregoing specification, it shouldbe understood that the invention is capable of embodying a. wide variety of modifications in detail structure without departing from the spirit of thepresent invention or the scope of the appended claims.
