The apparatuses which are in use at the present time for permanent hair-waving are attended with serious drawbacks. Such apparatuses usually comprise a certain number of tubes which are 5 employed for heating purposes and are provided with electric resistances by which they may be raised to the proper temperature; into each tube is inserted a lock of hair which has been first wound upon a curl-paper and surrounded by a sachet impregnated with a suitable solution. It is necessary to continue the heating for several minutes in order to convert the solution in the sachet into vapor or steam. This operation is uncomfortable for the person under treatment, and there is also danger of burning and of electrocution. It is further required, in order to prevent any leaking vapor from burning the scalp, to close each sachet by means of a pair of pincers which it requires great care to place in position and is also a cause of pain. On the other hand, the use of special sachets for containing the chemical products necessary to provide for the permanent waving, is relatively expensive.

The present invention relates to an apparatus for permanent waving, by which all such drawbacks will be eliminated. For this purpose, the apparatus essentially comprises a pair of pincers consisting of two tubular branches, each of which carries at one end a hollow jaw whose semi-cylindrical inner wall is perforated, and the branches are enabled to communicate with the jaws by a set of valves. The other ends of the said tubular branches are respectively connected by a flexible conduit with a steam boiler and with a return chamber provided with a suction device.

It is simply necessary to press successively between the jaws of the pincers each lock of hair which is wound upon a curl-paper, while making the connection between the said jaws and the tubular brancheain order to assure a circulation of steam in the lock of hair and to produce the waving in a rapid manner.

The invention will be better understood from the following additional description, with reference to the accompanying drawing which is givenby way of example:

Fig. 1 is a diagrammatic general view of a form of construction of the apparatus.

Fig. 2 is a perspective view of the pincers on a larger scale.

In the device herein represented, 1 is the boiler for producing the steam, which is tightly closed and is provided with a pressure gauge 2, and with other instruments for safety and control. The 55 said boiler contains a suitable quantity of liquid, such as a solution of borate of soda or the like. The heating may be effected by electric resistances 3, by gas, or by any other means. At the top is located a neck 4 for the outlet of steam, which may be optionally provided with a cock.

Below the boiler is situated a chamber 5 containing an electric motor 6 upon whose shaft a suction fan is mounted. This chamber communicates with a neck 8 for the return of the steam, and it contains a vessel 9 for the condensed steam.

On the necks 4 and 8 are mounted two respective flexible tubes, of rubber or the like, which are fitted at their. other ends upon two respective tubular branches l2 and 13 which are suitably shaped and pivoted together in such way as to form a pair of pincers. To the respective outer ends of these branches are secured two hollow jaws14 and 15, and the internal conduit of each branch leads into one of the said jaws. The inner walls 14a, 14b of the jaws are semi-cylindrical and are suitably perforated.

The internal conduits of the branches 12 and 13 are normally closed by valves which are controlled by respective buttons 16 and 17 adapted for automatic return, these being situated opposite one another.

The operation of the apparatus is as follows:

After having wound the locks of hair upon curl-papers and placed the boiler 1 under steam, each lock is pressed between the pair of jaws 14-15. When the branches 1213 are brought together, this places the buttons 16--17 in contact, thus opening the corresponding valves. The steam from the boiler arrives through the conduit 10 and is delivered by the perforations of the jaw 14 through the lock of hair, the steam being at once drawn out into the jaw 15 and then returning through the conduit 11 into the chamber 5, thus avoiding all condensation of steam in the hair.

Obviously, the invention is not limited to the form of construction herein described and represented, but is susceptible of all desired modifications.

I claim:

1. An apparatus for permanent waving, essentially comprising a pair of pincers consisting of two tubular branches carrying at one end respective hollow jaws whose semi-cylindrical internal wall is perforated and with which the said branches may communicate by a set of valves, the other ends of the branches being respectively connected by a flexible conduit with a steam boiler and with a return chamber provided with a suction device.

2. An apparatus for permanent waving as set forth in claim 1, the valve of each branch being provided with an external-control button which is pressed by the opposite branch when the pair of pincers is closed, thus assuring the automatic and simultaneous opening of the suction and delivery conduits for the steam.
