DEVICE FOB PRODUGING PERMANENT UNDULATION.
Application led- September 11, 1922. Serial No. 587,412.
To all whom t mal/y concern:
Be it known that I, RUDOLF EICHENBER- GER, citizen of thfe Republic of Switzerland, residing at Rennweg 35, Zurich, Switzerland, have invented a certain new and. useful Improvement in a Device for Producing Permanent Undulation, of which the following is-a specification, reference being had therein to the accompanying drawing.
In order to produce an undulation effect on hair and particularly on womens hair that remains for a long time, it is known to subject the latter to a treatment in which single plaits of hair are moistened with a liquid and are wound around sticks which' are then placed inside electrically heated tubes hung up on wires supplying the electric current. By this treatment a drying of the hair and a permanent undulation of the' latter results. Y
According to the present invention the device for producin permanent undulation comprises a curl-stlck shaped as a tube for winding the hair thereon and a heating cylinder adapted to receive the curl stick, a cord being lixed with its one end to said curl stick, the other end of the cord passing through the hollow curl stick and forming a loop in which the end of the plait of hair can be clamped. A second tube may be loosely mounted inside the curl-stick, a spring being provided which tends to pull; a conical portion at one end of the inner tube into the outer tube and to prevent thereby a turning motion of the two tubes relatively to each other.l The curl-stick may also be provided withl laterally projecting members which maybe detachab y arranged, and around which the plaits of hair may be wound in order to produce a special Wave vof Fig. 1,
Fig. 5 is a plan view of the heating cylinder, some parts bein partly remoyed,
Fig. 6 shows a cur -stck according to a Fig. 9 shows. on an enlarged scale a .curlstick according to a second constructional example,
10 is a longitudinal section and Flg. 11 is a side view of the curl-stick according to Fig. 9.
yReferring now to the heating cylinder illustrated in Figs. 1-5, 1 denotes an inner tube having apertures 2 approximately in the middle of its length, so that the upper and the lower part of tube-1 are connected together by narrow bridge-parts 3. Around the upper part a heating body 4 is arranged and around the lower part a heating body 5 1s prov1ded, the heating eiect of the heating body 4 being weaker than that of the heating body 5, caused for instance by alesser number of windings of the heating wire coil. 6 denotes a cover or shell.- Between the latter and the heating bodies there is the heating space 7. This space 7 is in its lower part in connection with the surrounding air by means of air inlet ports 8 and in its upper part by means of air exit ports 9. The cover is provided with two apertures 11 leaving narrow bridge parts 12 yof the solid material; the apertures 11 being arranged between'the heating body 4 and the switch 10 made of an insulating material, for instance of libre., The switch 10 is of a known construction; by turning the pins 13 around the axis ofthe heating cylinder through a determined angle the current is cut in and out. A plurality of heating cylinders are suspended in a known manner from the wires 14?i supplying the electric current i'n order to treat several plaits of hair simultaneously.
The curl-stick according to Figs. 6-8 comprises an outer tube 14, in which an inner tube 15 is loosely inserted. A compression spring 16 which bears with its one end against a collar 17 on the inner tube 15 and with its other end against the tube 14 vtends to pull the inner tube into the outer tube 14 in the direction of the arrow shown in Fig. 7. The inner tube is provided at its one end with` a conical portion 18, the latter being partl 4 ulled into the tube 14 by the pressure o t e spring 16, as is shown in.
Fig. 7. When the conical portion 18 bears against the outer tube 14 it acts like a conefriction coupling and any turning of the tubes 13 and 14 relatively to each other is prevented. If a pressure is exerted on the inner tube in the direction of the arrow shown in Fig. 6 the cone coupling is put out of action and the tube 14 may be turned on tube 15. One end of a cord 19 is fixed to the conical part 18, the other end 20 of the cord passes through the tube 15, in this manner a loop 21 is formed.
The afore described device is worked as follows:
The loop 21 is placed around a plait of hair 22 near the head and is clamped by pulling the loop together. Thereafter the plaitof hair is wound around the curlstick in the manner illustrated in 'F ig. 8 and the upper end 23 of the plait is fastened by means of the end 20 of the cord, the cord 20 being thereby clamped in between the coils of the spring 16. In order to still further tighten the windings of the plait of hair on the tube 14 pressure is applied to the collar 17 so that the tube 14 can be turned rel.
atively to the tube 15, which is held stationary, by this turning motion the plait of hair is tnsioned. Then the wound hair is covered by the wadding 24 being wound around it and further by an envelope of paper 25, which envelope is tied together at its lower end 26, the upper end being left untied so that any vap'our can escape. Now the heating cylinder is placed over this enveloped part of the hair on the head, the envelope filling up the inner pipe 1. Thereafter the current. is switched in and the hair thus treated is subjected toa drying action for some time.
The circulation of air through the apertures 8 and 9 presents the advantage, that the cover 6 does not become so hot as to cause a burning in case the cover comes inadverteutly into touch with the head. The heating effect by means of the heating body 4 is weaker than that of the heating body 6, as the hair is in its natural state already dryer at its ends than at its roots. ,For this reason the apertures 2 are provided which prevent .any comparatively great transmission of heat from the lower part to the upper part of the tube. The apertures 11 serve to prevent as much as possible a transmission of heat to the-switch 10. Another advantage of the device consists in the fact that in consequence of the provision of the loop 21 below the conical part 18 a heat insulating pad is formed of the portion of the hair passing through the loop. With other known apparatus the skin of the head came into touch with the curl-stick at this very spot whereby a disagreeable transmission of heat resulted.
In the constructionalvexample illustrated in Figs. 9-11 the curl-stick comprises a tube 28, into which laterally projecting members 29 are inserted. The members 29 are provided with holes 30 at their parts rotruding intothe tube, so that all the mem ers 29 can be secured in position by means of a rod 31 penetrating through said holes 30. The members 29 are provided with oblong heads 32. To the lower end of the tube 28 a cord 2O is fastened for forming the loop 21. With this curl-stick the plait of hair can be Wound around the former in a more complicated manner than shown in Fig. 8, as the plait 22 on being wound around the tube 28 can also be wound around the members 29. After the hair Wound upon the curlstick 28 has been treated in the heating tube and the latter has been removed, the rod 31 is pulled out'of the tube 28 and all the members 29 can be removed so that the pla-it of hair can readily betaken oif the curl-stick.
