rIliis invention relates to an electrical hair waver of suchconstruction thatwit may be used `by an individual in the treatment ot, his or her own hair, or may be used by hair dressers generally.
The principal object of this invention is to provide tines er prongs ot bow shape ot such construction and arrangement that they will elevate and dispose the hair in loops between two electrically heated pressurebars to thereby expedite operation as well as producing waving and undulation of improved y 'form and more rattractive appearance than ordinary. i Other objects more speciic will be vei;- vplained hereinafter; Y Y
The yinvention is fully 'described herein and` isillustrated in theaccomp'anying drawings wherein; Y Fig. 1 is a view of vthe device in longitndinal section showingthenormal'position of the bow-shaped tines or prongs. Fig. 2 isa'sec'tional detail showing the position ot parts when tl'ie'p'rongs have'been elevated.

Referring now'to the drawing for a more particiilaif description.4 Vthe hairl waver consists in part of a pair of handles 1-1 which, in the drawings, are shown broken ,Nuinerals "12: lan'dl?) indicate a pair' of heated metallic pressure-bars, "eachy being rigidwith "a handle, these parts'being con nected "to permitpar'allel moveiiients by means otra' pivot '14 'andlever bars.-
The bar 12 is `preferably semicircular in cross lsectionand vtlie`i-"-"b,a`r 13' iscircular in cross section, and vit *willl be 'understood 'that Y ythehandlesinay be grasped in the hand of an operator to cause the bars to movetoward each.l other Jfor pressing the hair therebe-l Y tween. f Y
These parts have been in general use for the treatment othair and no claim of no-veltv is made. for theuse of heated bars. ,u-
rhese hollow bars may be electrically heated, and for this purpose I have shown electrical conductors A and B adapted to be energized by any suitable source or elec'- trical supply, each hollow bar being provided with an electricalcoil (not shown) for communicating heat to said bars.
`The bars 12 and 13 may 'be pressed toward each other, subject to `the resistance of a spring 15, said springl operating to normally cause said bars to'remain in spaced relation as shown in Fig. 8 ot the drawings.
In order that hair, during operation may be elevatedv to 'form the loops, as first mentioned,1 and this movement vof. the hair will be coincident with the movements, toward each other,l 'of the pressurelbars, I provide v,certain partsto now be described.
Y, Numeral 16 indicates a carrienplate upon which are pivotally mounted, a. plurality of bow-shaped. prongs 17, 'said plate being adapted tofbeV reciprocated longitudinally by means to be described."
" NumeralV 18 indicates a supporting plate Vwhich isv disposed above the plate 16,'and-'is stationary with the casing 19, by means' of a pair othangersor arms 19 and19 and at 2O are indicated a pair of links each having pivotal connections at the ends oi the .plates 16 and 18.
'The supporting-,plate isfprovided with for receiving the upper end portions of the bow-'shaped prongs and it will be understood that if the carrier-bar is moved forwardly the prongs will have a corresponding" movement, and that the prongs will swing rear- Y wardly when Vthe carrier-bar moves rearwardly The'toiward movement of the Vprongs is caused by the movement toward eachother,
Vwill swing rearwardly and the pressure'fbais icc ' of the handles, and 'during this'movement f CII will more outwardly l'roni eath other, the movements heine coincident.
The. movements last mentioned lor the how-.sluiped pronos, is etlieeted hv means ot a laz v-tongs 2l, in emijunetion with a pair o-[ eriissslevers Q2, the latter heing pivotall'v mounted on the pivot pin lil. The rear part ot the lazy-tongs is mounted pivotall)T on the hanger 19.
llv referring' to hire'. d oit the drawings .it will he seen that a movement ot the handles toward each other will cause a forward nniven'ient ol the Carrier-plate tor the reason that the pin 23 will he moved 'forwardllxx said pin heilig" mounted in the Afront i nrt of the loer-tong and also having;- a mountingI in the jtront end portion ot the Carrier trame. said lazy-tonos having` a pair oi' keepers (l sliding-lv mounted in the Curved slots .D ot the lazytonrs- Numeral 2l indicates a spring;- which provided lior the lazy-to. s to Cause the Currier plate to move rearnnrdlyv when the handles niove outwardly from each other.
Numeral indicates a slot which is provided in the supportingl plate tor receiving the pin Q3.
It will thus he seen that the movement tow ward each other, ot the pressure-hars and forward swinging movements of the pronos will he simultaneous when the handles are moved toward each other.
The keepers C will also move to -ard each other in the curved slots l) of the lauff-toiir the result heini; that the tonos will he en tended and the pin will move in the slot 25, .its movement being;` :forwardly of the deviee lor moving` the Carrier-plato At'orivardlv, and since the pivotal mountings ot the prongs are hetiveen the ends ot said prongs, they will swingr ifmvvardlv, elevating the hair, and since the hair will he ele *ated at the time it is pressed between the heated hars l2- and 't3 it will l ave the looped t'orm desired.
The easing' operates to conserve the heat, also it provides a support for some oit the olierating.;` parts and is open at its hottom` its lower edges heinir provided with niunerous teeth 2h whieh. during operation. engage the scalp.
The teeth operate to dispose the prongs in spaced relation relative to the scalp.
The device disposed transversely. of and upon the hair.
ln operation the handles are then moved toward eaeh other, the result being that the prongs will elevate the hair in the torni of a loop between the pressure-hars, and said hars will he moved toward each other for heating' and pressing the hair.
.ln Fig. 2 ol the drawings, a strand ot the hair 2T, is shown to illustrate its position hetween the pressure hars.
In this view onlj,7 a part ol the device apn Loft? pears to he utilized, hut it will he understood that, in practice, all ot' the prongs may engage the hair to form the loops.
Means are provided :tor maintaininp,- the pressurehars parallel with eaeh other so that the pressure upon the hair will he praetirally uniform.
For this purpose each pressure-har is provided with a pivot-pin .Ext 22, is indicated a pair of actuating' levers disposed in crossed relation and mounted upon the pin lil.
lilaeh lever i722, is pivotally n'iountrd at one ot its ends on a Wrssureliur and its opposite end is provided with a slot. Q9, lor reeeiving` a pivot pin 253.
trllots are equi-distant A.trom the pivot pin lst and when the handles are moved toward eaeh other, the presfsure-hars will remain parallel relative to ear-.h other during all ot' their movenients.
lllhile I have shown and described speeilie construction lor the device l do not limit myself to torni, size, proportions or minor details, and changes mayv he made as found to he ot znlvantage without departing from the spirit of the invention, said Changes heing` within the scope oli the invention as claimed.
