ROBERT P. SIMMONS, OF CLEVELAN'D, OHIO.

ELECTRIC HAIR WAVER.

Application filed July 30, 1923. Serial No. 654,632.

To all whom it may concern:

Be it known that 1, ROBERT P. SIMMONS, a citizen of the United States, residing at Cleveland in the county of Cuyahoga and Ohio, have invented a certain new and useful Improvement in an Electric Hair aver, of which the following is a specification.

This invention relates primarily to hair waving implements and JIIIOIB particularly to the construction of an electrical appliance which may be electrically heated by a connection with the usual electric lighting Source for imparting artistic and attractive wave formsto the hair.

One ofthe objects of my invention is to provide an electric hairwaver which 13 simvple in construction and capable of inexpensive manufacture on a quantityproduction basis.

Another object of my invention is the provision of a heating element which may be deformedfrom a shape in. which it is readily manufactured into the shape of the wave hairff, V

A furtlier-"ob'ect of the-invention is to provide a pair oi" plates having the shape of the wave forms to be given to the hair,

forms ii'lllcll lt is desired to impart to the which plates maybe fitted together with the heating "element between them but so closely related to the plates that substantially the entire quantity of heat generated by the heating element is immediately conducted their temperature to a predetermined degree and maintaining that temperature .e tliciently ing process. v .1.

A stillturther objectof my invention is ineans for gently but fir nly pressing different portions of hair from its extremity to a position closely adjacent'ithe head against the wave forming plates whereby to impart an artistic and attractive wave to the hair appealing to the esthetic sense.

Another object of the invention is to pro forming heating element for imparting limited lateral movement to the hair during the period that pressed against the heated wave forming plates to secure! a French style of wave in the hair.

Other and further objects of my invention will be pointed out in the following specification and the appended claims with parduring the hair wav- .wound upon the base,

NT orr cs.

ticular reference to the accompanying drawin sin which:

igure 1 is a plan View of the heating element used in the hair waver of this invention, the insulation around the heating wires being broken away to clearly show the con struction of the element; this view shows the element in its manufactured shape before it has been deformed to the shape in which it is used in the hair waver; Fig. 2 is a cross sectional view of the heating elements shown in Fig. 1 before it is deformed to the shape in which it is employed in the hair waver; Fig. 3 is e perspective view of the heating element with the insulated covering removed 'illustrating the slfiipe to which the heating element is deformedfor use in the hair assembled electric hair waver, the outside plate of the wave forming portion being broken away toshow the position of the heating element between the wave forming heated plates; Fig. 5 is a longitudinal cross sectional view through the wave forming plates of my electric hair waver taken on line 55 of Fig. 6 which, is a cross sectional View taken laterally through the hair waver heating plates and heating element; Fig. 7 1s a perspective view of my invention having detachable means for laterally moving the hair while it is pressed inthe wave forming plates for imparting a French wave to the 12111; and Fig. 8 is a cross sectional view of the detachable comb-like member positioned at the top of the wave forming plates for laterally inovingtlie hair in certain limits while it is being pressed in the waver.

My invention contemplates forming a heating elemcnton a sheet of insulating material which is bent about a mandrel for the purpose of winding. After the wire is.

further insulation HEISSUED material" is wrapped around the element which insulates the heating wire from contact with the metallic surfaces hereinafter described. After the heating element is completed it is deformed, .warped or pressed out ofits original flat shape into an approximate W shape or a wave form corresponding approximately to a sine wave orthe wavelike form it is desired to impart to the hair. An extremely thin heating unit'is thus. provided by the process described. I insert this thin unit between apair of me tallic surfaces correspondingly shaped in wave form tothe form obtained by the heating element. The metallic surfaces are uniformly and instantaneously heated to the hair down into her is pivoted desired temperature substantially by conduction. A hollow stem and handle/is ar ranged to support and manipulatethe hair wave-shaped surface and maintained in tension for a period sufiicicntfor it to become .et. in the wave shape of theplatcs. A.

. French style wave may he imparted to the stood by more particular reference predetermined desired temperature.

' between their inner 95 secured firmly in position with respect to forms a protective casing 'plates 6 and hair by employing an attachable comb-like structure slidably mounted on the middle crest portionof the wave-shape plates in such mannei t'hat heat is conducted to the comb from the heating element. The comb maybe reciprocated within narrow limits drawing the hair backward and forward at the crest point the hair being firmly secured by the. prongs at the extren'iity of the loops of the wave-shapcd plates, preventing the hair from following the action of the comb.

My invention will be more clearly under to the drawings in which reference character 1 designates a mandrelwhich is used in winding the heating element. An asbestos sheet 2 is wrapped around the mandrel forming the core of the heating element. .i\'[1('it or any other insulating material may of course be used as a core ll101Ill)l.. \Vhen mica is used slots are cut on each side to prevent the'tiirns of the resistance wire from slip ping whereas in the ease of asbestos the wire bites into the soft asbestos which prevents the turns of the wire. from slipping and shorting. The. heating wire is wound I on the core 2 and the leads fixed as indicated at 5. The element is next wrapped with insulation material 4 such as asbestos which around the heating element preventing electrical contact with the

metallic sheets

6 and 7 and also serving to reduce the heatv developed to a The eating element is now deformed "from its flat shape into a. W or approximately sine wave shape as shown in Fig. 3. Metallic 7 also of wave form are arthe heating element inserted ranged with faces and the plate 6 lar Wave imparted to the wave by operating the comb plate 7 by a turned over edge 8. The midle or crest portion of the wave-shaped plates. 7 is of a reduced vertical dimension for. a part of its length to enable the-sup i porting stem 10 to be inserted between the.

plates

6 and 7 which stem is provided With a haiidle 11 to facilitate the manipulation of. the hair waver. The stem and handle are hollow to permit the connection to heatin element at 5 to be extended throu 'h the device to the flexible. exterior-conned tion 12. At' a point 141 on supporting stem 10 l pivot a lever 15 having prongs 16 and 1.7 which pull the hair down into the crevices vor the extremity of the loop portions of the waver pressing the hair against the crest or middle portion oi the plates and against the walls 18 and 19 of

plates

6 and 7. The lever 15 is manipulated by means of a handle 20 which is closed with reference the to handle 1.1 as indicated in dotted lines at 21 when the hair is forced down against the hot plates by means of prongs 16 and 17.

A detachable comb-like. structure. 22 may be provided with a portion-extending ,over the crest portion of the wave-shaped plates whereby heat is transferred by conduction t to the comb and to the verticalteeth 23. The hair is normally laid over the waveshaped plates, the prongs16 and 17 being raised out of )laee,- wit-lithe strands enter ing between the several teeth of the comb and then the prongs. 16 and 17 closed down pressing the hair against the hot. plates and drawing the strands tlirough'tlie comb. The prongs 16 and 17 maybe knurled. to firmly anchor the hair. The comb 22 may then be reeiprogated by moving trigger 26 on arm, 24 backward and f01WitI(l,'tli0 comb being guided with relation to the stem 10 by means of depending members. 25.

hair by"; pressing it against the wave-shaped plates may now be modified to a French style .or snake 7 22 within the limits pcrmitted...by the hair being secured in the lowermost portion of the waveshaped' platesu y v v r The arrangement of my electric hair waver is such that the waver may be moved over e difl'erent parts of the hair and a wavy appearance imparted to the strands of hair, as desired, moving the waver into close proximity of the head.
