Description

March 14, 1944. J. LECLABART 2,344,097
HEATER FOR PERMANENT WAVING Filed July 7, 1939 Patented Mar. 14, 1944 HEATER FOR PERMANENT WAVING Jean Leclabart, Courbevoie, France; vested in the Alien Property Custodian Application July 7, 1939, Serial No. 283,283 In France July 8, 1938 2 Claims.
My invention relates to heaters for permanent waving and its main object is to provide such a heater which is heated on heating bars and restores the accumulated heat by means of a graduating device, thereby avoiding the suddenness of the shock at the instant when the heater is placed on the hair.
Other features and advantages of the invention will become apparent from the ensuing description taken in conjunction with the accompanying drawing which shows diagrammatically and merely by way of example, one embodiment of my invention. In said drawing:
Fig. 1 is a vertical section of a heater according to my invention.
Fig. 2 is a perspective view of said heater.
Fig. 3 is a plan view of one of the jaws of the heater.
According to my invention, the parts I, l of the jaws l0, ID of the heater are made arcuate-shaped in order to increase the path through which the heat restored by the heat accumulator blocks 2, 2 travels at the instant when the heater is placed on the hair and thereby avoid too sudden an increase of temperature of the hair. If the heat had to travel through the entire circuit formed by the jaw parts I, I, the heat exchanges at their point 3, 3' would be greater than at their ends 4, 4'. Therefore, provision has been made for connecting the ends 4, 4' to the heat accumulators at one or a plurality of spaced points by means of small metal hinges 5, 5' in order to cut down the passage of heat by conduction.
The whole arrangement including metal blocks 2, 2' thus constructed is mounted on cover elements or parts 6, 6' made of plastic material, the two arcuate jaws l0, I0 being covered on the external sides thereof by said plastic parts 6, 6' and being connected together by means of springs 1, the movements of said jaws being independent of each other and of the springs; said springs preventing the jaws from opening. Jaws l0, Ill are pivoted on a ball 8 for which a housing 9 is provided in each of the jaws, thereby enabling the jaws to take up all the necessary positions about the lock of hair, irrespective of the regularity of the curls thereof. Ball 8 has an extension 8a which protrudes through a bridge 1a connecting the springs 11. The extension 8a is provided with a head 8b which rests upon bridge Ia. Finger gripping members Illa, lllb are respectively connected to jaws l0, ID for manipulating the said jaws against action of springs 1.
While I have illustrated and described a preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
I claim:
1. A heater for permanent waving, comprising two arcuate-shaped metal jaws adapted to be heated on heating bars and transfer the heat to the lock of hair on which they are to be placed, each of said metal jaws including a base portion and a tip portion, a metal block secured to each base portion of said jaws and forming a heat accumulator for said jaws, said blocks having each a complementary ball socket part,
a ball fitting in said socket part, means for resiliently urging said jaws together, and spaced apart heat conducting means extending between the base of said jaws and said blocks in order to prevent heat exchange from being greater at said tips of the jaws than at the bases thereof.
2. A heater for permanent waving comprising two arcuate-shaped metal jaws adapted to be heated on heating bars and transfer the heat to the lock of hair on which they are to be placed, each of said jaws being provided with a base portion and a tip portion, a metal block secured to the base portion of each of said jaws and forming a heat accumulator therefor, each of said blocks having a ball socket part therein, a ball fitting in said socket parts, means for resiliently urging said jaws together, spaced apart heat conducting means extending between the base portion of each jaw and its adjacent block in order to prevent heat exchange from being greater at the tip portions of the jaws than at the base portion thereof, and cover means made of heat insulated material extending externally of said jaws.
