8 Claims.

This invention relates to methods and devices for curling and waving hair, and is more particularly concerned with cold permanent waving methods and devices useful in forming spirally woundcurls commonly known and referred toas ringletspr pin curls.

It has heretofore been the practice in the art of permanent waving of "hair by cold wave solutionsto first saturate-a tress of hair with the wave solution, then to wind the saturated tress of hair from its end inwardly toward the scalp around a cylindrical curling rod to form a Croquignole curl, then to apply a neutralizing solution to the tress-of =hair while-the latter is in its wound condition on the Croquignole curler, then -to remove the 'Croquignole-curl from :thecurler and rinse thecurl in clear warm water to remove the cold wave-solution and neutralizer, and then to manually form the rinsed tress of hair into one or more pin-curls which are secured flat-against'the scalp by hair pins, bobby pins, or other types of fasteners.

The present invention contemplates amethod and device for cold permanentwaving of hair in which a tress of hair is first spirallywound upon a ringlet curler to form a pin curl. -While the pin curl is still in its wound condition on the curler, it is saturated with a cold wavesolution, neutralized, rinsed and dried, thus effecting a material saving in time and labor.

'This invention further contemplates the provision of a pin curl forming device on which a tressof hair may be spirally wound either from its end toward the scalp "or from the scalp outwardly toward its end, after which the tress is locked in its wound condition upon the device and-treated with solutions to-form a'permanent wave inthe hair.

This invention further contemplates the provision of a pin curl forming device adapted to rapidly produce a uniform curl without injury to the hair.

Another object'of this invention is to provide a ringlet type hair curler adapted to be snugly engaged against the scalp directly above the roots of a tress of hair wound upon the curler, the tress-being preferably wound on the curler, from the'rootoutwardly to the extremity of the hair totform a fiat dress curl, such as pin curls,'finger curls, sculptorcurls or ringlet curls. The use ,of thetpresenthair. curler eliminates the formation of fish hooks at the extremities-ofthe hair caused by curling the tress inwardly from the endstoward the roots on end curlers.

.This invention further contemplates the --provision of a hair curling device of skeletal .con-' struction adapted to permit the cold wavesolu: tion, neutralizer, and rinse water to permeate lthe innermost strands of the wound tress to obtain a complete saturation thereof.

It is a further object of this invention to pro vide a hair curling device embodying a skeletal spool upon which a tress of hair may be wound, and a skeletal cap to fit over and'lock a wound tress upon the spool. By forming the spool'and cap of lightweight material, such :as a th'ermoplastic, it will be apparent that a largenumber' Fig. 3 is a plan view showing the spool upon which a tress of hair is wound.

.Fig. 4 is a side elevational view-of same.

Fig. 5 is a sectional view taken-along the line 5-'-5 of Fig. 3.

Fig. '6 is a top plan view showing the'locking' cap'removed from the spool.

Fig. '7 is a side elevational view of same.

Fig. 8 is another side'elevational view of-the locking cap.

Referring now to the drawingfo'r a better understanding of the present invention, the hair curling device is shown as comprising a spool '2' adapted to receive a spirally woundtress of hair, and a cap 3 adapted to be positioned upon and interlocked with the spool to secure thewound tress against displacement from the'spool.

'The spool 2 is of one-piece'skeletal construction comprising acentral ring-shape -hub-4 joined to the medial portion of a plurality of circumferentially spaced, generally U-shape ribs 5 ;arranged to define an annular groove G to receive a wound tress 'of hair, the ribs being preferably arranged in pairs a, b, c, and d joined-together attheir ends at 1. Each pair of ribs a, b, c,'and d :is reinforced by meansof aninterconnecting portion 8 extending therebetween and joined' thereto, and each set of:ribs is joined toanadjacent set'of ribs by means of braces 9 arranged on opposite sides of the hub 4. winding a-tress from its root'end ou tward ly,,one of the "braces"! isomitted-from each end ofthe To facilitatespool to provide unobstructed openings at l0 and H between the ends of two adjacent sets of ribs, as illustrated in Fig. 5.

The cap 3 is of one-piece skeletal construction embodying a plurality of arms l2 joined together at their inner ends at I 3 and diverging outwardly and upwardly to merge with the upper portions of associated depending legs [4. As illustrated in Fig. 6, the legs M are arranged in diametrically opposed pairs diverging downwardly from their junctures with their related arms.

An upwardly projecting finger engaging portion "5 is provided above the juncture of each arm l2 with its associated leg M to facilitate mounting and removal of the cap relative to the spool. The lower extremity of each leg is formed with a relatively wide foot I! having a protuberance 18 on its inner face for locking engagement under a brace 9 on the spool, and it will be noted that each foot extends below the adjacent end of the spool when the cap and spool are in assembled relation, as illustrated in Figs. 2 and 5.

In the use of the hair curling device shown and described, it will be noted that the ends of the spool 2 are identical in order that either end of the spool may be positioned against the scalp S to receive a wound tress of hair H and the locking cap 3, as illustrated in Fig, 5. It will also be noted that recesses l9 are formed in the hub 4 between adjacent ribs 5 to permit the passage of fluids to the innermost coil of a tress wound on the spool, and that the ends of each pair of ribs a, b, c, and d are formed with inwardly converging faces 202l) to guide a tress of hair into the annular groove 6 during the winding operation.

ment therefrom by engagement of the protuberances l8 under the braces 9 adjacent the scalp. As the foot portion I! of each leg extends below the end of the spool adjacent the scalp, mounting of the cap acts to move the spool away from the scalp, see Fig. 5, to facilitate subsequent operations.

After a tress of hair has been applied to the spool 2 and locked thereon by the cap 3, the hair is saturated with a cold permanent wave solution, then neutralized, rinsed and dried before removal from the curler. By forming the spool and cap of skeletal construction as herein shown and described, it will be noted that liquids and heated air are adapted to pass freely to all portions of a tress of hair wound within the groove of the spool. To provide a relatively strong, lightweight, inexpensive construction, the spool and cap are preferably molded from a suitable thermoplastic material.

While this invention has been shown in but one form it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit and scope of the claimed invention.
