May 10, 1932. s. E. MELKMAN HAIR WAVING DEVICE Filed Feb. 26, 1930 [nvenimr Patented May 10, 1932 UNITED STATES PATENT @FFICE HAIR WAVING DEVICE Application filed February 26, 1930, Serial No. 431,509, and in Canada February 27, 1929.

The present invention relates to improvements in hair waving devices especially of the type employed for forming lasting Marcel waves.

5 An important object of the invention is the provision of a hair waving device which will form the curls and waves quickly and in a lasting manner.

A further object of the invention is the provision of a hair waving device having a mandrel disposed for partial circumferential movement to impart an ironing or calendering effect to the hair.

Another object of the invention is the provision of a hair waving device having a mandrel mounted for oscillating movement.

Still another object of the invention is the provision of a hair waving device embodying amandrel mounted for partial circumferential oscillating movement and means for operating the mandrel to efiectively press the hair.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawings forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the 39 same Figure 1 is a perspective view of the assembled waving device;

Figure 2 is a longitudinal sectional view through the same; Figure 3 is a transverse section taken on the line 33 of Figure 2, in one position;

Figure 4 is a similar view showing the mechanism in opposed position, and v Figure 5 is an enlarged transverse section taken on the line 5-5 of Figure 2.

Referring to the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 10 generally designates a transversely elongated casing formed in the upper portion of its front wall with an opening and in the lower portion of its rear wall with a rearwardly directed annular flange 11. The up- W per portion of the casing 10 supports a man drel 12 embodying an exterior metallic shell portion of the mandrel 12.

13 of elongated tubular form carrying at its interior an electric heating element 14. One end of the mandrel is disposed in theupper ortion of the casing 10 and is journalled for partial circumferential movement there 5 A rearwardly extending casing extension 15 is attached to the flange 11 and is formed at its rearward extremity with a comparatively fiat, transversely elongated gear housing 60 16. An extension section 17 extends rearwardly from the lower portion of the housing 16 and forms a conduit for a poweroperated drive shaft 18.

Journalled within the casing extension 15, 65 so that one end projects within the lower portion of the casing 10 while the opposed or 70 on and operates within the lower portion of .the casing 10. The gear 20 is disposed immediately below and is in mesh with a complementary spur gear 21 fixed on the inner The rear end of the transmission shaft 19 carries a crank 22 rigidly fixed on the shaft and provided with a depending arm 23 in the outer extremity of which is mounted a rear- .wardly extending pin 24. 0

On the forward extremity of the drive shaft 18 is fixed a crank actuating cam 25 embodying a flat annular plate rigidly secured to the drive shaft and formed at its forward the cam groove 26 so that the crank 22 will be oscillated upon rotary operation of the cam 25.

The heating element 14 of the mandrel is on electrically connected with a source of electrical supply through the medium of conduc- 30 is bent to assume an arcuate form in cross 10o section designed to conform to the exterior contour of the mandrel shell and to clamp the hair on the mandrel over practically the entire length thereof. The opposed end of the clamping member is formed with a rearwardly extending operating handle 31 disposed for convenient adjustment by the operator.

In use,-the strands of hairare initially arranged flat upon the mandrel 12 andare firmly clamped thereon by adjustment of the clamping jaw '30. The electric heating element is energized and the drivingconnection properly efi'ected so that the mandrel will be actuated in a partial rotary movement or rather circumferentially oscillated. This movement of the mandrel simultaneously with the heating, will producean ironing or calendaring efl'ect to the hair sothat the Marcel waves will be rapidly formed 'in a lasting manner.

It is to be understood that the form of my invention herein shown and described is to be=taken as a preferred example of the same, andthat'various changes-as to the shape, size, andarrangement of parts may-be resorted to without de'partingfrom the spirit of the invention' or the scope of the subjoined claims.

-Havingdescribed my invention, I declare that what I claim and desire tosecure by Letters Patent is 1. -A hair waving device comprising a casing, a hollow'm'andrel having'one end jour- 'nalled in the casing, a clamping member operable to clamp the hair on the mandrel, means within thema'ndrel for heating it, and mechanism for circumferentially oscillating the said mandrel independently of the clamping member. a

2. In a hair waving device, a casing, a mandrel having one end projecting in the casing and journalled therein,-a clamping 'memlow'mandrel having one end journalled in the casing, a clamping member operable to clamp the hair on the -mandrel, electric heating means disposediin the mandrel, a rotar drive shaft, and actuating means operative y connected with the drive shaft and with the mandrel adapted-to impart a circumferential oscillating movement to the mandrel upon rotary operation of the drive shaft.

4. Ina hair waving device, a casing, a hollow mandrel having one end journalled in the casing, a clamping member pivotally connected with the casing operable to clamp the hair on themandrel, electric heating means within .the mandrel, a transmission shaft 7 journaalled in the casing, and intergeared with
