PERMANENT HAIR WAVING OR CUR-LING- DEVICE Continuation of application Serial No. 521,819,;fi1ed March 11, 1931, and in France December 31,1980. This applicationfiled December 29, 1931. Serial No. 583,617. 1

The present invention relates to a permanent hair waving or curling device, heated either by borrowed heat or fitted with electrical heating elements and is a continuation of my co-pending application filed March 11th, 1931, under Serial No. 521,819.

A simplepermanent hair waver, for individual home use has long been sought, but difficulties were experienced in obtaininga heating oven having a sufliciently tight closure to maintain a given steam temperature over the desired period and at the same tnne permit the steam to escapewithout injury to the unskilled operator, or the scalp or halr. '15 Heretofore the heating surface which was necessarily at a high temperature would burnthe hair due to the direct contact of the metal therewith or to the concentration of heat at. a given point.

A principal object of the present invention is therefore to'provide a heating oven formed by two cup jaws adapted to fit one into the other, and to avoid point concentra tion of heat caused by bolts, nuts, rivets,

I screws etc. by using as aheating surface for the hair a flanged cup member which is adapted to beforced into each of the aforesaid cup jaws.

Another object of my invention is to provide a handy permanent, hair-waver or curler of the utmost simplicity, whichfis capable of being safely and easily used by unskilledpersons. i I H With these and other objects in view, the invention is characterized by the arrangement and combination of parts as disclosed in the following detailed description of the accompanying drawings and asset out in the appended claims. I

In the accompanying drawings: Fig. 1 is a side view of a hair-waver according to the invention. I

The hair-waver according to the invention comprises two round hollow shells or cup jaws 1 of even thickness mounted on the han-, dle portions 11 which cross each other, being pivotally hinged externally at their point of intersection. Said handles may be formed'by metal bars when borrowed heat is used, and, in the case of heating by means of electrical resistance elements, said handles are made of hollow metal tubing of square, rectangular or round cross-section so that the flex wire 9 carrying the electric current can pass through them unobstructed.

In the case of the electrical waving iron the pivot hinge 2 is composed of a piece of metal tubing 2 (Fig. 5) brazed on to each hans dle 11 at theirpoint of intersection, with a bolt 2 passing therethrough, the assembly thus forming a pivot which obviates the pos sibility of shortcircuit or shock caused by the pivot wearing and the covering of the wire fraying. When borrowed heat is used, the hinge 2 might be simply a rivet passing through both handles.

The handles 11 may be grasped by means of wood portions 11 which cover said handles and act as insulators. p

The cup jaws 1 are fixed to the ends of the handles 11 by screws 12 and one of said cup jaws lisformed with a flange or lip 3 adapted to receive the rim of the other cup. jaw

so that said cup jaws when brought together 109 form a closed container or oven. Each cup jaw has a semi-circular opening 14 formed in its rim, said two openings being in register when the jaws are brought together and forming an aperture through which the strand of hair can pass. Aeration holes 15 acting as an exit for the steam are likewise formed in the cup jaws 1.

Each of the round cup aws 1 is provided with a heating surface formed by a metallic cup i which is forced into the associated cup jaw and provides a housing for the electric re sistance elements 6 wound on an insulating sheet of mica 5 and between which and theunder face of the top of the cup l is inserted a second sheet of mica 5 while two sheetsofmica =5 and a sheet of asbestos 8 are inserted between the resistance 6 and the base of the cup jaw 1. The resistance elements 6 are connected to the flex wire 9 which passes through insulators 10 located in the cup jaws 1..

A wire spring 16 can be fitted to the ban dles 11 if desired, such wire spring tending to maintain said handles open.

The method of preparing the hair prior to its insertion in the hair-waver has been illustrated in Figs. 6-11 inclusive.

The strand of hair to be waved is first moistened. with a suitable liquid and rolled on an ordinary flexible curler 17. 'A strip of gauze 18 is then wrapped round the lock of hair in the manner illustrated in Figs. 7 and 8, after which the curler 17 is bent round and its ends twisted together as shown in Fig. 9. A flannel bag 19 is then passed over the bent curler, after which it is inserted in the cup jaws 1 and protrudes therefrom through the opening 14, thereby forming an insulator between the waving iron and the scalp and the waving iron and the strand of hair. The cup jaws 1 can be fitted with a fibre attachment 1 L mounted at the edges of the opening 14- so that a double insulator is thus formed. The electric current having been switched on, the device is heated by the resistance ele ments which disposed as they are, transmit heat uniformly throughout the cup 4 since no screws, bolts or rivets are used in fixing the latter. Moreover the flannel bag contai1.- ing the strandof hair is also uniformly heated and any steam given off by the liquid with which the hair is moistened escapes through the holes 15. In the event of the hair being left for an excessive length of time in the cup aws 1, the flannel bag, which scorches in from 35 minutes, provides an effective signal to call the attention of the operator to the fact that it is time to release the strand of hair. The strane of hair on being released comes out permanently waved without injury to the hair.

The device as hereinbefore described is preferably heated by electric elements, but it can also derive its heat from a gas ring, a spirit lamp, etc. in which case theelectric elements are suppressed, and, in order to retain the heat longer, a metal disc 13 is placed between the handle 11 and the cup aw 1.

I have found that cotton flannel is a very satisfactory material for making the bag and that by lining the latter with aluminium or tin foil 20 (Fig. 10), the heat is rapidly absorbed and retained, thereby enabling the operator to pull apart the cup jaws and inspect the bag without the temperature dropping due to heat loss. Moreover the effect of the aluminium or tin foil is to distribute the heat evenly and thus to avoid possible burnin of the hair. Moreover the flannel bag a ords an indication as to the state of the hair. Thus when the bag is browned, it is an indication that the hair is permanently waved.
