GEORGE EDWARDS BJRKMAN, OF PARIS, FRANCE.

QWABATUS FOR PERMANENT UNDULATION.

Application filed December 11, 1826, Serial No. 154,137, and in Yrance November 16, 1926.

The present invention relates to apparatus for permanent unduiation with aid of electricity and its object is to devise an apparstus superior to those known hitherto.

5 According to the invention use is made of a hair-curler provided with electric resistances for heating, the lock of hair being rolled on this curler and held thereon by means of a tie forming a protector.

Usually, the locks to be submitted to undulation are firstly rolled around of curlers and maintained by means of strings or otherwise, whereupon they are placed into the interinr of a heating apparatus, tubular and is provided, for example, with an electric heating coil surrounding the chamber of vaporination of the apparatus.

A treatment of this kind is long and complicated.

According to the present invention, instead of introducing the curlers into heavy end voluminous apparatus, use is madeof c special type of curler heated inwardly by inner resistances in the manner employed already for the electric curling irons.

In order to maintain the lock onthe curler, two pinqers are utilized, formed by two rods articulated, the one on' the other and pressed close by means of any suitable device; the

as one of the pincer-s forms, moreover, the protector and carries, for this purpose, two soil; plates of indie; rubber or the like; rolled around each of the branches of the pincers, fixing-if applied against each other, the curler by means of n other pincers, preventing thereby the love from getting loose, concentrating the hair and protecting the soul at the same time. T e apparatus constructed in this manner cu constitutes, in comparison with apparatus utilized hitherto, a real progress, being much lighter and dispensing with the usual crown or collar suspended from the ceiling as well as with pincers', strings andso on. V I The invention will he better understood "with reference to the drawings appended -"showing, in the way of an example, one preferable executional form of the subject-matter of the inv ntion. re Figure 1 shows the detail of the curler,

Eights the u per pincers, I

figure th. e pincers forming at the same time a d a protector, and

Figure 4 repress the ap status after egg of the hair lioeh and cosing of the The curler consists of a metal rod 1 preferably nickel-plated and provided inwardl with a resistance in the manner existing 1: ready in the electric curling irons.

' At one extremity of the curler a head. t ebon te or other insulating substance 4 isprovided, carrying the usual terminals 5 for its connection toa prolongator 6. v

A band of gauze 2 retained by asperities or hooks 3 (o tained by sim le cuts in the metal) serves to protect the air-lock from direct contact with the metallic rod 1. According to the case, one or several la ers of gauzefor example, for treatmento white hair-are rolled around the curler, the yellowing action of heat on white hair by heatmgrtoo strongly not recommendin itself.

be two utilized pincers can e of-any suitable type, for example of the one represented in Figure 2, comprising two. metal branches 7 forming an articulation at 8 and pressed against each other by means of a ring 9. g

The pincers could comprise two elastic branches, arcuate and kept together by means of a small spring pivoting and form-. ng a hook at its one extremity suchdevice needing no other means in or or to keep closed the pincers, one single movement being suflicient in order toclose and to hook on he two branches.

The pincers could be also, as represented in E18. 3, in form of fastening racks-l0. with curved extremities 11, in shape'of 90 spatulas in order to facilitate handling, similarly to ,the surgical instrumentl,

Independently of the type ldopted, the lower mcers '(F i ure 3)" ca rolled on each 0 their branc es, two flexi 0 plates 12 95 of indie rubber, leather or other material soft and resisting and operate to form a protector. I

The upper pincers, ure 2) are bare.

In order to serve oneself with theapparatus, firstly the protector forming a tie 12 is placed in order to protect the long hair, and thereupon the hair-lock M is passed between' the twobranches 7 kept apart from the 105 on the contrary, (Figpincers. .Now these branches are closed and fixed, as alluded to or otherwise, for example by a ring.

The lock bein rolled on the curler and grotfictgd g0? ireet clrlmtfict w2ithfflrhesame yte an o uze-te 'psl o t protector are raise and then maintained opplied against each other by means of the second pair of pincei's (Figure 2) kept close in the manner stated previously.

The soft plates 12 applied a ainst each other retain and concentrate the lieat, fix at the same time the-curler, prevent the lock from getting loose and protect the long hair.

If the hair has been already undulatcd by permanent undulation, it will be frequently sufficient and. preferable to undulate only the roots, the extremity of the lock M surpass-' ing in this case freely between the lips 12 of the protector, as represented in Figure 4 and the said lock being hence only partly rolled around the curler. I I

. This feature constitutes a very great advantage of the apparatus because avoiding a very rapid deterioration of hair by an excessive heating, which advantage cannot be realized with the other apparatus known hitherto.

Cotton stoppers 13 or better still, wedges of india rubber are utilized in order to raise the curler and to increase the protection of the scalp. i

The invention is not limited to the single executional mode as described and permits the most different modifications without dcparting from the scope of the main inventional idea.

that I claim is 1. In an apparatus for permanent undulation with aid of electricity, a metallic rod, an electric resistance therein, layers of gauze on said rod, plates of soft material to receive ,the hair-lock between them'and the gauze,

one pair of pincers to receive the free ends of said plates in order to fasten them, and

the two branches of thesepincers to keep them closed,

3. In an a paratus for permanent undulation with aid tric current, a metal rod, an electric resistance within the same, terminals for the resistance, layers of gauze on said rod, means of heat'g'eneratcd by an elecon said rod to maintain the said gauze applied against said rod, plates of soft material, one pair of pincers for attachment thereto of said plates, another pair of pinccrs for keeping applied'against each other said plates, and fastening means for the two branches of said latter closed.

4. A heating element, presser plates, and means to arrange said presser plates in spaced relation to opposite sides of the heating element to hold strands of hair adjacent pincers to keep them said opposite sides of said heating element,

and to releasabiy secure said presserplates in such position, said means comprising two pairs of pincers. Y

In witness whereof I aflix my signature,
