ELECTRICAL HAIR WAVING AND CUBLING DEVICE.

Application filed September 20, 1926. Serial No. 136,469.

This invention relates to a device for waving or curling hair, and has for its object, broadly, to provide electrically heated holders upon which the hair of the individual may be wound, supported or held to cause waving, fiat-waving or curling, said holders to be of such form that they will be conlid venient in use and will heat the hair unitormly and without injury. The invention includes a plurality of holders so arranged that they may be operated under control of an individual for self-treatmentot his or her own hair or may be used by hair dressers generally, means being provided for heating the hair uniformly as to degree of heat and duration of exposure to heat.

With these objects in view and others to be mentioned hereinafter the invention presents a novel and useful construction, combination and arrangement of parts as described herein and claimed and as illustrated in the accompanying drawing, it being understood that changes may be made in form, size, proportions and minor details without departing from the spirit of the invention,

said changes being determined by the scope of the invention as claimed.

Referring now to the drawing for a more I particular description, we provide alpluralityof holders 6 for supporting the hair to be treated, each holder consisting, in part, of an elongated casing 7 preferabl constructed of metal so that it will not ecome injured b action of heat, but will operate as a goo conductor of heat. While these holders have been shown in the drawings to have a greater width than thickness, they maiy be circular or elliptical in cross-section.

owever, for producing wavy forms and eflects, it is preferred that the width of a casing shall be greater than its thickness and that a pair of opposed grooves orlongitudinal depressions 8 be employed at the an electrode 11, said core being constructed of vulcanized rubber or other electrical insulating material and provided longitudinally with an aperture 12 for receiving the rectilinear part at of the electrode. Also the core is provided in one of its ends with an aperture 13 for receiving an end-portion of the electrode and anaperture 13' at its opposite end to provide a mounting for the clamp 14.

lhe insulating core 10 is also provided to open on one of its ends with a pair of metallic sleeves 16 to operate as sockets in electrical communication with the ends of the coiled part of the electrode and the rectilinear part a: thereof.

As thusdescribed the parts may be conveniently manufactured, and may be readily assembled. After the electrical insulating jacket 9 has been inserted in the casing the core 10 with its electrode 11 may then be inserted within the jacket, all part of the electrode and said sleeves being completely insulated, electrically, and the jacket 9 and core 10 may be secured to the inner wall of the casing by any suitable means, plugs 17 of electrical insulating material, such as vulcanized rubber, being shown for this purose.

lhefllamping-bar 14 is of loop-form and is arranged to swing from one of the ends of the casing, said bar or loop engaging in the aperture 13' of the core 10, as best shown in Fig. 2 of the drawin s, and in operation the clamp or loop may e swung outwardly to permit the hair to engage the casing, and

.when the bar is swung inwardly the hair till conductors 21, each of the last named con-' ductors being ,provided with a plug or pair of prongs 22 for engaging in the sockets of a holder; and an operator, after the holders have been placed in position for treatment of the hair to produce waving or curling, may then place the plugs or prongs in the sockets of the cores of the several holders, and on account of electrical action the casings and hair thereon Will become heated. The switch 20 may then be used for terminating the electrical current to said holders, and the plugs 22 may be removed from the sockets. and after the holders have be- 1clome cooled they may be removed from the air.

Numeral 23 indicates a covering or jacket with which the resilient clamp or loop may be inserted, if desired, to prevent injury to the scalp, it being understood that the growth of hair may be abundant in some instances and may be scanty in other instances, and the jacket for the clamp may be used if needed. The jacket 23 is preferably constructed of rubber, but any other flexible material may be used, operating as a non-conductor of heat.

It will be noted that the curved parts of the electrode are disposed closely adjacent tothe casing, and therefore the holders will become quickly heated after the electric switch 20 has been moved.

Among some of the benefits to be derived by use of the invention, it may be stated that by the means described the de ree of heat will be practically uniform for t e several holders, this being accomplished by subjecting the holders to heat during a specific period of time, each holder also being subjected to the same degree of heat, thereby avoiding injury to the hair and producing uniform waving or curling. The holders are of such construction that they willbe convenient in use; and since the parts are few they may be manufactured economicall Wt claim as our invention,

1. A hair waving and curling device comprising a metallic casing for supporting the hair provided with grooves inits opposed sides, an electric heating element disposed in said casingfand aclamp of loop form mounted to swing from the casing for pressing the hair into said grooves of the casing.

2. A hair waving and curling device comprising a casing having grooves in its opposed sides, an electric heating element in said casing, and a substantially Q-Shaped clamping member pivoted on said casing and having its side portions adapted to rest in the closed position opposite to said grooves whereby to force the hairinto the grooves, said casing and clamping member having an interlocking means for holding the clamping member in the closed position.

In testimony whereof, we-have afiixed our signatures.
