Aug. 6, 1 J. SCHNEIDERMAN PERMANENT WAVE ROD Filed Nov. 5, 1934 fl/MTM 07170 rngys.

Patented Aug. 6, 1935 UNITED STATES PATENT OFFICE 9 Claims.

This invention relates to hair waving or curling rods and more particularly to rods for use in connection with electrically heated devices for enveloping the rods and hair wound thereon to produce so-called permanent waves.

While the rods herein shown and described may be used in various ways and to provide various types of waves or curls, they are particularly adapted for use in so-called helical permanent 10 waving in which a lock of hair is spirally wound along the length of the rod and a heating attachment is clamped over the hair and rod to provide the desired permanent curl or wave.

It is an object of the present invention to provide a permanent wave rod for use in connection with the usual heating and steaming devices and which will produce a more natural wave than has heretofore been possible. It is well known that fine hair is very difficult to wave and it is necessary that it should be very carefully wrapped and stretched during its application to the rod.

It is therefore an object of this invention to provide a rod which may be more easily held and turned during the wrapping process than are the usual rods, and in which there will be less tendency for the rod to slip in the fingers.

It is also an object to provide a rod having a cross-sectional contour as well as a longitudinal contour on which hair may be very snugly wrapped and stretched and in which the crosssectional contour of the rod is such that there will be little if any tendency of the rod to slip and allow the hair to loosen thereon during the winding or after it has been clamped or otherwise enclosed in a heating device.

It is a further object to provide a rod which will produce a natural wave when the hair is wrapped thereon in any of the various ways which are common in the art; that is, the hair may be wrapped flat or with a half twist or threequarter twist or in any other desired manner, and

a particular curl will be retained until the permanent wave is obtained.

Further objects will be apparent from the specification and the appended claims.

In the drawing:

Figure 1 is a side elevation of a helical rod which is provided with helical flutes or grooves, and

illustrates one embodiment of this invention.

Fig. 2 is a transverse section taken on a line corresponding to line 2--2 of Fig. 1.

Fig. 3 is a side elevation of a tapered fluted rod and illustrates another embodiment of this ll invention.

Fig. 4 is a transverse section taken on a line corresponding to line 44 of Fig. 3.

Fig. 5 is a side elevation of a helical rod similar to that illustrated in Fig. l but without the helical flutes. 5

Fig. 6 is a transverse section taken on a line corresponding to line 6-6 of Fig. 5.

Referring to the drawing in detail, the embodiment illustrated in Figs. 1 and 2 comprises a tapered helical spiral rod adapted for use with the ordinary steaming and drying devices and is provided with a handle i having the usual axial spindle 2 secured thereto and which is indicated by dotted lines. An elongated tapered helical curling member 3 is mounted for rotation on the spindle 2 and is retained in position thereon by means of the usual cap 4 which may be screwed onto the end of the spindle 2 in the usual manner. The curling portion 3 is usually rotatable, relative to the handle I, in one direction only, and is prevented from rotation in the opposite direction by means of the usual one-way clutch which is ordinarily mounted within the handle I. This general type of construction is similar to those in common use and further detailed description of the parts, other than the curling member 3, is believed to be unnecessary. The entire rod may, of course, be formed from a single piece of metal or other suitable material if desired.

The tapered member 3 forms a conical spiral; that is, it is not ordinarily formed of a twisted rod but, instead, the helical axis of the convolutions forms a conical spiral around the longitudinal axis of the cone, and the conical axis is preferably within the cross-sectional contour of any part of the rod, whereby the spindle 2 is always enclosed therein.

The member 3 is also formed to provide spiral flutes or grooves 5 between corresponding spiral lobes 6. This is particularly illustrated in cross section in Fig. 2. It will, of course, be understoodthat the member 3 may be made of comparatively thin tubing, if desired, or may be of a single piece of material as illustrated in Fig. 2 and provided with a longitudinal opening 1 through which the axial spindle 2 passes. In using this rod, the small end 4 is preferably placed adjacent the scalp and a lock of hair is spirally wound around the rod, substantially as indicated by the dot and dash line in Fig. 5, and then enclosed in a suitable heating means. Of course, other types of winding may be used if desired.

Figs. 3 and 4 illustrate a somewhat different embodiment of the invention in which the curling member 3 is not in the form 0! a spiral but is merely tapered toward the retaining member 4!. The member 3 is, howevenprovided with longitudinal flutes 8 .between corresponding lobes s as illustrated. The shape of the rod in this embodiment provides a very pleasing wave, and the longitudinal flutes 8 prevent the slipping of the rods in the fingers and prevent loosening oi the hair.

Figs. 5 and 6 illustrate a conical spiral rod similar to the rod illustrated in Fig. lwith the exception that the spiral member 3* is not fluted as previously described, but, instead, is cylindrical in cross section and may be formed from a sheet metal tube as illustrated in Fig. 6. The dot and dash line In illustrates the usual method of winding the hair on the rod, although it will be understood that it may be wound in any desired manner.

The flutes l and 8 provide ventilation under the hair during the steaming and heating operation and permit quicker drying, and in certain types of winding the spiral shape also assists in a like manner.

It will be understood that in using this invention, the hair is wound on the rod and then steamed, and when dry retains the natural wave induced by the shape of the rod, thus providing a particularly attractive permanent wave having a characteristic appearance not obtainable with the rods ordinarily used.

The device presents many advantages over prior structures and various modifications may be made without departing from the spirit of the invention. It is desired, therefore, that the invention be limited only by the prior art and the scope of the appended claims.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:

1. A permanent wave rod of the character described ior a heating and steaming device comprising a handle, a spindle on said handle, a

conical spiral curling member mounted for rotation around said spindle, with said spindle completely enveloped by the convolutions, and means for retaining said spiral on said spindle.

2. A permanent wave rod for a heating and steaming device, comprising a rigid elongated metal member having a plurality of longitudinal flutes therein with rounded lobes therebetween,

said flutes being of suflicientwidth to cause permanent undulations in the permanent waves of hair wound and steamed thereon.

3. A permanent wave rod for a heating and steaming device, comprising a rigid elongated metal member having a plurality of longitudinal lobes thereon forming substantially V-shaped flutes therebetween, the vertices of said lobes being sufliciently spaced to cause permanent undulations in the permanent waves of hair wound and steamed thereon.

4. A permanent wave rod for a heating and steaming device, comprising a rigid elongated tapered metal member longitudinally lobed in cross section, said lobes tapering in accordance with the taper of the rod and being sufliciently spaced to form permanent undulations in the permanent waves of hair wound and steamed thereon.

5. A permanent wave rod for a heating and steaming device, comprising a tapered metal rod forming a high pitched spiral with the axis of the rod entirely within any cross sectional contour.

6. A permanent wave rod for a heating and steaming machine, comprising a tapered metal rod forming a conical spiral, the material of the rod completely enclosing the axis of the cone, said rod also being provided with circumferentially spaced relatively deep spiral flutes with rounded lobes therebetween, said flutes being of sufflcient width and depth to form permanent undulations in the permanent waves of hair wound and steamed thereon.

7. A permanent wave rod for a heating and steaming device, comprising a rigid elongated metal member of small diameter and having a plurality of alternate longitudinal flutes and rounded lobes, said lobes intersecting substantially at their diametral axes to form flutes therebetween, said flutes being of sufllcient width to cause permanent undulations in the permanent waves of hair wound and steamed thereon.

8. A permanent wave rod for a heating and steaming device, comprising a rigid elongated metal member of small diameter and having four arcuate longitudinal flutes, the contour of said rod being symmetrical in cross section whereby said flutes cause permanent undulations in the permanent waves of hair wound and steamed thereon.

9. A permanent wave rod for a heating and steaming device, comprising a rigid elongated and tapered metal member of small diameter having a plurality of alternate longitudinal and rounded lobes, said lobes tapering in accordance with thetaper of said rod, and intersecting substantially at their diametral axes and arranged to form permanent undulations in the permanent waves of hair wound and steamed thereon.
