HAIR GURLEB.

hpplicatian filed February 16, 1927. Serial No. 1625, 234.

This invention relates to devicesfor curling and waving hair and particularly to the curler or curling stick upon which the hair is wound.

In using curling sticks of this type, a clip is usually used for clamping a strand of hair at a point near the scalp, after which the free end of the strand is wound upon the middle portion of said stick. As the strand is wound up, it occupies more of the length of the stick gradually spreading from the middle of the stick towards the ends, for the reason that while the free ends of the strand of hair may be compressed into a small area, the hairs of the strand diverge over a much greater area as the scalp is approached. If the stick is made of one piece as has been heretofore customary, the hairs which arrange themselves near the ends of the stick are not wound tightly enough with consequent loss of eficiency 1n the curling or waving operation. I have therefore provided a stick wherein the ends are rotatable relatively to the middle portion and to each other in a direction efi'ective to wind up the strand thereon tightly.

The various objects of my invention will be clear from the description which follows and from the drawings, in which,

Fig. i is a front view of my improved curling stick showing how the winding of the strand thereon is begun.

Fig. 2 is a vertical central section of my device.

Fig. 3 is a section of a modification.

Fig. i is an end View of the same, and

Fig. 5 is an end View of the'same partly in section showin particularly the means for preventing backward rotation of the ends.

In the illustrated embodiment of my invention which shows one of the practical applications thereof, I provide a central portion 10 preferably ofthe same length as or somewhat longer than the separate end sections 11 of the stick. At its middle, the

diameter of the section 10 is least, the diameter of said section increasing adually towards the ends thereof in a suita le curve so that the shape of said section is substantially a hyperboloid of revolution or other suitably shaped concave cylindrical solid. Throu h the center of the section 10, is the coaxial y arranged longitudinal, cylindrical opening as 12 through which asupporting red as 13 may be passed in such a manner as to properly support said section, which be suitably secured to the rod as by means of a pin 14. It will be understood however, that the section 10 Ina be made of sheet material if desired, an similarly or otherwise secured to the rod, or that said rod and said section 10 may all be made of a single piece of material if desired. Annular shoulders as 15 are provided at the ends of the section 10, said shoulders bein of the proper depth to allow the ends 16 o the end sections 11 to fit thereinto in such a manner that the entire outer surfaces of the sections 10 and 11 are perfectly flush or even with each other with no space therebetween in which hairs may be caught. In other words the joint is tight and smooth to prevent possible catching of or injury to the hair or pain to the person whose hair is being treated. The extensions 17 at the extremities of the section 10 fit inside of the ends 16 and provide a bearing for supporting said ends 16 during the rotation thereof.

I prefer to have the outer extremities 18 of the end sections 11 greater in diameter than the inner ends 16 thereof the crosssectional diameter of said sections increasing gradually to provide a curved surface continuous with the surface of section 10. A base as 19 preferably closes the outer circular end of each of the sections 11 and has a central aperture 20 therein to allow the passag therethrough of the rod 13, said base being made preferably though not necessarily integral with the remainder of said end section.

For maintaining all three of the sections of the stick in place, the extremities 21 of the rod 13 are suitably threaded to engage the nuts 22, which are adapted to be tightened on said rod against the bases 19, whereby the parts are maintained coaxially in proper longitudinal and transverse relation, though said parts may be relatively rotated or readily detached tor repair, cleaning or the like, as will be clear from Fig. 2.

For preventing rotation of the sections 11 in the wrong direction, that is, in a direction tending to loosen the strand of hair wound thereon,. a ratchet wheel as 23 is secured to the rod 13 as by means of a suitable pin 24, ratchet teeth as 25 inclined in the proper direction being cut on the'face of said wheel. For engaging the teeth 25, a spring projection 26 may becut fromthe base 19 as by means of the parallel curved slits 27 and 28 and the radial slit 29 joining lid said slits, the material between said slits being then bent inwardly so as to lie preferably in a plane substantially parallel to the axis of the rod 13, or a separate spring member may be used for this purpose if preferred, The projection 26 is made of suliicient length to engage the teeth 25 and to prevent backward rotation of the section 11, It will be understood however, that any suitable clutch arrangement allowing rotation in one direction only may be sub stituted for the ratchet and the ratchet engaging means shown.

n the o eration of my improved stick, a strand oi? hair 30 of suitable size at the scalp to cover the greater part of the stick when wound up, is arranged substantially about the middle of the section 10 and the stick is turned toward the scalp in the usual manner thereb winding up the strand upon said section. ince the free ends of the hair occupy a substantially less width than that occupied by the root. ends of the hair, as the stick is rotated, the strand tends to spread longitudinall upon the stick, gradually reaching an being wound upon the sections 11. Because of the divergence of the outer hairs of the strand 30, said hairs are not wound ordinarily, tightly upon the sections 11, if said sections are rotated together as a unit or given the same number of revolutions as the section 10. It therefore besaid sections being gripped at the ends 18 thereof.

In order to provide means whereby the end sections 11 may be rotated with considerable force as is sometimes necessary when the hair is wound tightly thereon, I prefer to rovide suitable'projections 35 projecting ongitudinally from the ends thereof. Sai

pro ections may be formed if desired, from the material of the bases 19 by means of suitable slits as 36 in somewhat the same manner as the projections 26 are formed.

' For bracing the projections 35 and for allowing the 1nsertion of a suitable rod, 21 pin as 37 may be riveted to said projections 35 as clearly shown in Figs. 3and 4. By means of thisconstruction pliers or other tools may .be inserted between the projections 35 in order to exert greater force thereon than would be ordinarily possible with the fingers alone. Suitable knurling 31 is provided at said ends 18 so that the ngers may obtain a firm hold u on said ends; It will be noted that the sections 11 cannot rotate backwardly being held in place by means of the nesaoae projection 26 which engages the teeth 25.

' It will be seen that have provided an. eficient curling stick in which all of the hairs of a strand may be tightly wound, which is simple in construction and eflicient in operation. Various changes fronrthe preferred structure shown are contemplated,

die hairs of the strand on theirotation of said section, and a pair of end sections, each adapted to have the outside hairs of the strand wound thereon and each mounted coaxially with, and for rotation relatively to said middle section.
