v ofY mercuryenclosed in' saidgglass .'tubeandwhich i fisici the;usua1'form. `In other'words,A thebody .of'mercury which: is intended to' respond tothe heat oftl'ieihair is comparatively short. .Incase an opening or iissure occurs in the hair: in" the region of .the body of mercury, the temperature is higher than that of tl e hair for the reason that the hot vapor from the heated pad passes directly to the bulb of the thermometer and the thermal indicator gives a false reading which is higher than it should be.

One of the objects of my invention is the provision of a combined hair curler and thermal indicator which gives the average temperature of the bar on which the hair is wound and of the hair itself which is wound on the bar.

A further object of my invention is the provision of a bar on which the hair is wound and which is formed of good heat conducting material, preferably aluminum.

Other novel features of my invention will appear in the specilication and will be particularly pointed out in the claims.

My invention will best be understood by reference to the accompanying drawing in which I have illustrated the preferred embodiment therer of good heat conducting material, preferably aluminum, on which the hair to be curled is wound. The bar is provided with an axially extending, elongated opening l i in which is received a hollow cylindrical stem I2 of a thermally respiral actuating .element I3A is.: anchored iat one end; as at I4,A to the wall-oftheistem l2rnear one end .thereofv Ywhile .the ropposite: end I5' thereof is freezto.l rotate. .'I'o the free; end of ,the spiral: coil .xisvattachedzashaft or spindle.v I6 having its. bearing-,at l ina metaliicimember f8 secured inthe stem: l2. .Ji-.pointer l9is attached totheiouter `end 'ofi the .'shaft' I 6 and moves .over .aqdial I 9 l which is enclosed in a casing 2..which.is,tiniturn, secured to the outer end of .thev.stem|2, the

.The'clip 23iisipiv0- tally mounted as at 24 on the bar l). Referring now to Fig. l, 25 is a clamping device comprising two sections pivotally connected together, only one of such sections being clearly shown in Fig. 1. Such clamping device is of well known form and as the same constitutes no part of my invention, the same is not fully illustrated.

In using the device embodying my invention, a wisp or lock of hair is selected, and the clamping device 25 is placed over such lock close to the scalp oi the patron, the end of the lock is then wound around the bar lil and the clip 23 is then placed over the lock. As soon as the bar with the clip is turned, the hair is secured in position on the bar by the clip, and the hair also secures the clip in position. When the lock of hair is completely wound around the bar and the clip, the bar with the hair wound thereon is attached to the clamping device 25 by placing an extension 26 of the bar IS in a support 2i, the opposite end of the bar being provided with a ratchet 28. By turning a handle E@ on the bar, the winding of the hair is completed, a pawl 3G mounted on the clamping device 25 engaging said ratchet and retaining the bar in position in an obvious manner.

It will be understood that the hair indicated at 3l is now surrounded by a pad 32. It will also be understood that the pad is treated with a well known curling solution which assists in perfecting the curling operation.

Heat is now applied to the pad 32 and in the embodiment of my invention illustrated an electric heater indicated generally at 33 and cornprising clamping bars 34 and 3M are pivotally connected together as at 35 and a spring 36 interposed between the two bars tends to force two segments 31 and 31| towards each other and against the pad 32. It will be understood that the segments 3l and 3H are provided with electric heaters to which are connected respective leads 38 and 38I, the heaters extending along substantially the entire pad and bar l in Fig. 1.

When the segments are disposed as illustrated in Fig. 1 and current applied to the electric heater, the heat is transmitted to the pad 32, to the hair and from the hair to the bar I0. In turn heat is conducted from the bar to the bimetallic spiral coil and as the bar is formed of good heat conducting material, it is rapidly and evenly transmitted throughout the entire bar,

and as the bi-metallic spiral coil is disposed in good heat conducting relation to the bar, the lat'- ter is subjected to the average temperature of the entire bar and is not aiected by local condithe curling operation is complete.

While I have described my invention in its preferred embodiment, it is to be understood that the words which I have used are Words of description rather than of limitation. Hence, changes within the purview of the appended claims may be made Without departing from the true scope and spirit of my invention in its broader aspects.

What I claim is:

1. In a hair curler of the character described a metallic bar formed of good heat conducting material on which hair may be Wound, said bar being provided with a longitudinally extending elongated opening, means for applying heat to said bar along substantially the entire length thereof, an elongated heat actuated element receivable in said opening and extending throughout a substantial portion of the length thereof, said element being anchored at its inner end and rotatable at its outer end, and means connected to the rotatable end of said element for indicating the position of the outer end of said element and thereby indicating the average temperature of said bar.

2. In a hair curler of the character described, a metallic bar formed of good heat conducting material on which hair may be Wound, said bar being provided with a longitudinally extending elongated opening, means for applying heat to said bar along substantially the entire length thereof, a bi-metallic spiral actuating element disposed in said opening and anchored at one end to said bar and rotatable at its opposite end, and means connected to the free end of said coil for indicating the average temperature of said bar.

3. In a hair curler of the character described, a metallic bar formed of good heat conducting material on which hair may be wound, said bar being provided with a longitudinally extending elongated opening, means for applying heat to said bar along substantially the entire length thereof, a bi-metallic spiral actuating element disposed in said opening and anchored at one end to said bar, the opposite end. of said element being rotatable, a rotatable shaft connected at one end to said actuating element, a dial, and a pointer connected to said shaft and Vmovable over said dial.
