ATTORNEYS Patented Mar. 1, 1 932 UNITED STATES PATENT OFFICE HOWARD R. KIRK, OF IILARCHMONT, YORK, ASSIGNOR T GIEIN'ERAL PERMA- NENT WAVE CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK METHOD OF AND MEANS FOR WAVING HAIR BY STEAM HEAT I Application filed February 11, 1931. Serial No. 515,003.

Heretofore where steam heathasbeen utilized for permanently waving hair it has been difficult, if not impossible, to prevent the leakage or dripping of the water of condensation from the heaters for the wound tresses, said water of condensation because of its great heat tending to scald and burn the scalp of the person being'treated. Furthermore, it has been diflicult to so remove the heater at the end of the steaming operation that more or less ofthe water of condensation will not come into contact with the person being treated.

The object of my invention is to effectually overcome these difliculties by the formation of a partial vacuum in the heaters either during or after the steaming operation or both during and after the steaming operation, said partial vacuum serving to efiiectually draw the water of condensation from the heaters.

Practical means for carrying out my invention are represented in the accompanying drawings in which: 7

Fig. 1 represents a steam hair waving apparatus in which a vacuum pump is employed acting as a suction means for drawing the water of condensation from the wound tress heaters by forming a partial vacuum therein;

Fig. 2 represents a detail longitudinal sectional view of one of the heaters; and

Fig. 3 represents a diagrammatic detail view showing a steam ejector acting as a suction means for drawing the water of con densation from the heaters by forming a partial vacuum therein.

The construction, arrangement and operation of the several parts of the illustrated steam hair waving apparatus is as follows A suitable supporting standard for the various parts is herein shown as comprising a base 1 and a hollow upright 2 having a lateral or overhanging branch 3 terminating in a depending branch 4. In the form shown in Fig. 1 a bracket 5 is mounted on the standard upright 2 and serves as a support for a boiler water feed pump 6, a vacuum pump 7 and their driving electric motor 8.

A second bracket 11 is mounted on the standard upright 2 and serves as a support for the boiler water feed tank 12.

A third bracket 13 is mounted on the standard upright 2 and serves as a support for the tank 1 1 which receives the water of condensation from the wound hair heaters.

These three brackets 5, 11 and 13 may be vertically and rotatively adjustable on the standard upright so that they may be brought into the desired relationship to each other and to the steam boiler.

The steam boiler 15 which supplies the steam to the wound tress heaters is shown as suspended from the depending branch 4 of the standard upright 2, which boiler may be provided with a steam dome 16. Means such as an electric unit 17 may be employed for heating the boiler.

The hair waving appliances per se, which include the mandrels 18 on which the tresses are wound and their steamheaters 19 form the subject matter of a copending application 7 filed by me of even date herewith, its serial number being 515,004.

The heaters may be suspended from the standard upright with their inner or scalp ends lower than their outer ends by any well known or approved means, not shown herein.

As all of the hair waving appliances are alike and are connected up in the same way to the boiler, to the receiving tank and to the suction means, one only of said appliances and its connections will be described.

The higher outer end of each of the heaters is provided with a steam inlet nipple 20 and an exhaust nipple 21. The exhaust nipple 21 has a suction tube extension 22 leading to the lower inner. or scalp end of the heater along its under side, through which extension the water of condensation is drawn.

The steam inlet nipple 20 is connected by a flexible tube 23 with a steam chamber 24,

which steam chamber is in turn connected to the steam dome 16-of the boiler by a pipe 25 provided with a hand valve 26.

The exhaust nipple 21 of the heater is connected by a flexible tube 27 with a nipple 28 -which projects upwardly to a point near the top of an exhaust chamber 29, the bottom of which chamber is connected through a pipe 30 with a suction chamber 31 common to all the heaters, said chamber surrounding the depending branch 4 of the standard upright 2. This pipe 30 is also provided With a hand valve 32.

The boiler water feed tank 12 is connected to the boiler feed pump 6 through a pipe 33 having a hand valve 34. The feed pump itself is connected to the boiler 15 through a pipe 35.

The common suction chamber 31 is connected to the condensate receiving tank 14 through a pipe 36 having a hand valve 37 adjacent the tank. A branch pipe 38 leads from the pipe 36 to the vacuum pump 7, said branch pipe having a hand valve 39 therein.

These pipes 35, 36' and 38 may be located for a considerable portion of their lengths within the hollow upright 2 and its branches.

The vacuum pump 7 is connected to the condensate receiving tank 14 through the pipe 40, and said tank 14 is provided with an outlet pipe 41 having a hand valve 42.

In Fig. 3 I have shown another form of suction means for forming a partial vacuum in the wound tress heaters to remove the condensate therefrom, said means being of the steam ejector type and including a small branch steam pipe 43 leading from the pipe 25 into the exhaust pipe 36, said steam pipe 43 having a hand valve 44 for controlling the operation of the ejector.

My method and apparatus may be used in several ways to insure the elimination of the condensate from the wound tress heaters. For instance, during the entire steaming operation the steam may be passed from the boiler through the wound tress heaters and back to the receiving tank together with its condensate by utilizing the suction means to form a partial vacuum in the heaters. \Vhere the vacuum pump 7 is used this result may be accomplished by opening the hand valves 26, 32 and 39 and closing the hand valve 37. Where the steam ejector is used the Valves 26, 32, 37 and 44 may be opened. I

'Also, thev hair steaming operation may be used without a partial vacuum being formed in the wound tress heaters by closing the valve 39 and opening the valve 37 and where the vacuum pump is used after the steaming operation has been completed, the valve 37 may be closed and the valve 39 opened, to produce the partial vacuum in the heaters for removing the condensate therefrom to the receiving tank 14. Where the steam ejector is used the injector hand valve 44 may be closed during the steaming operation and then opened after the steaming operation is completed, for forming a partial vacuum in the wound tress heaters to draw the condensate therefrom.

It will be understood that if so desired the suction or vacuum forming means may be utilized both during the steaming operation and thereafter ensuring the continuous Withdrawal of the condensate from the wound tress heaters.

To reduce the number of pipes 25 and their hand valves 26 the steam chamber 24 may feed a number of the heaters 19 through their flexible tubes 23.

Similarly, to reduce the number of suction pipes 30 and their hand valves 32 the chamber 29 may take care of the condensate from a number of the heaters 19 through their flexible tubes 27.

From the above description it Willbe seen that by forming a partial vacuum in the Wound tress heaters the Withdrawal of the condensate therefrom except the taken up by the wound tress, is insured and any danger of the leakage or drippng of the condensate on to the person being treated is absolutely eliminated.

It will also be seen that by utilizing this partial vacuum in the wound tress heaters the heaters will cool very much more quickly than where the condensate has been permitted to remain therein, thus allowing the removal of the heaters from the wound tress much sooner than heretofore.

It is evident that various changes may be resorted to in the construction, forms and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but
