(Care2- 33) This invention relates `generally to" apparatus for waving human hair' and more particularly to a rod for producing' the combination' of a Croquignole and a spiral waveron along strand of hair.

The principal object ofthis invention isy the provision of a hair waving rod constructed to produce a combination wave ina single strand of hair.

Another object is theprovision'of a hair Waving rod for producing a combination wavewhlch is adaptable for use with standard:Croquignole equipment,

Another object is the provision of a hair waving rod for producing aV combination wave ina long strand of hair. A v

Other objects and advantages appear I' in `the following description and claims.

In the accompanying drawing a practical embodiment illustrating the principlesfof this invention is shown wherein:

Fig. 1 is an enlarged side elevation of a hair curling rod, part of which is shown"in"se`ctio'n.

Fig. 2 is an end elevationof the rod taken on the line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 3--3 of Fig. 1.

Fig. 4 is a plan view of the rod with theend of a strand of hair placed under th'e'rod-clamp.

Fig. 5 isla plan view of'the rod 'illustrating lthe completion cf the Croquignole winding of the hair strand. f

Fig. 6 is a plan view of the rodillustrating the Croquignole' and the rst'part of the spiral winding.

Fig. 7 is a plan view of the rod illustrating the completion of the spiral winding;

Referring principally to Figf 1 of 'the drawing, Ill represents the rod which is' made of aluminum or other suitable material.` The length of this rod is the same as thatv f a standard Croquignole rod andit is constructed to't the same hair strand clamps andheatingapparatua The left end of the rod is preferably provided with a thumb handle I'I which is #secured Ain a transverse slot in the axially extending stud'IZ. If desired the thumb handle may Ibe omitted, in which case the stud is usually formed with asquare cross section for receiving a key to rotate the rod.

The stock from which the rod is made is approximately one-half inch in diameter, which represents the diameter of the ratchet gear I3 V formed on the rod adjacent the stud. This gear is ordinarily provided with twenty teeth, as

shown in Fig. 2. Inwardly adjacent the gear a narrow journal portion I4 is formed. This journal is substantially flush" with the bottom of the 4teeth of vthe gear and `is just wide enough to receive thefbearing mounted on a hair clamp` 5 From" this journal portion the rod is shaped inthe form vof 'a small spool I5 with arcuate conical =surfaces I6` at each -end thereof and a narrow neck portionI I1 approximately one-eighth inch inv diameter. The intermediate portion of ll0 the neck is knurled as indicated. If the length of the rod lbetween the spaced journal portions is approximately threeV and three-sixteenths inches this spool' should be approximately one and ve-'sixteenths long, or substantially one-45 fourth the length of the rod.

A cylindrical portion I8 joins the other end of the spool. This section is `approximately nine ythirty-seconds in diameter and one-seventh the length of the rod. The next adjacent section 20 I9 is Ifrustor conical in shape` and is slightly longerfthanu the section I8 and terminates in a diameter of` approximately three-eighths of an inch; A cylindrical section 2| is formed between the rounded' flange 20 and the frusto conical 25 section I9. Outwardlyadjacent the flange 20 the stock is cut Vto `a small ydiameter to produce the journal portion 22. The shoulder 23on the outer" end ofthe journal prevents the rod from shifting longitudinally of the hair strand clamp. 30

Agrasping finger 24, which is shaped to i'lt the contour of thatpart of the rod which it overlies, is provided with a centrally disposed depending ear `25 arranged to t within the slot 26 cutrin-an axial plane into the gear I3 and 35 therjournal I 4. This-ear is pierced to receive thefpin 21 which passes transversely through the gear as shown in Fig.`2. The journal I4 is out away adjacent the slot 26 to receive the grasping .finger 24; the surface Voi' the finger at 40 this'ipointacting as alpart of the journal when it is closed against the rod.

Thesmall spool'l section I5 voi the rod I ll is arranged ito'receive the outer end of the hair lstrand28 under 'the linger 24, as indicated in 45 Fig. 4; The hair 'is then wound straight onto the smallispool I5lin Croquig'nole fashion. When va:sufficient.length,ofthe hair strand is wound in thisv mannerfor producing atight ringlet at the end of the hair, the strand is gathered to- 50 ward the intermediate cylindrical section I8 as illustrated in Fig. 5.

The operator then continues to wind the strand in helical form around the intermediate cylindrical section I8 and up the frusto conical sec- 55 tion I9 and along the cylindrical section 2|, which produces a spiral as shown ln Fig. 6. The strand is then wound backon itself as indicated in Fig. 7. 'I'he extent of the spiral winding depends on the length of the strand of hair. If the strand is relatively short it need only loe wound partially up to the flange 20 and back to the center of the rod. If the strand is long then it may be wound to the flange 2D and back over the spool l5 and then returned to the center of the rod. The reason for terminating the winding in the center of the rod is to permit the hair to be spread out in both directions so that the strand may be uniformly distributed as it passes through the jaws of the hair clamp.

In this manner a combination Croquignole andspiral wave may be produced on a single strand of hair at one time. It will be noted that the winding of the hair is accomplished by rotating the rod in the hands in the same manner as that now employed to produce a full Croquignole wave. The shape of the rod comprising this invention permits this character of wave to be formed and facilitates the winding of the strand. This rod construction produces a tight Croquignole ringlet and a tight spiral wave because the hair may be drawn tightly on the rod at a pressure substantially as great as the clamping pressure applied by the hair clamp adjacent the scalp.
