6 Claims.

This invention relates to improvements in hair curling devices and more particularly to devices of this character for use in the cold set or roller method of hair curling.

It is commonly found that in the rolls and curls formed by this treatment the hair ends become unset and loosely curled sooner than the main body of the roll, thereby necessitating a resetting of the entire coiilure. Another difliculty experienced with cold wave rollers is that those in contemporary use may only be fixed in positions along the hair length a full or half revolution apart and when close to the scalp one position often leaves a short uncurled length of hair while the next succeeding position abuts against the scalp and draws the hair so tightly as to cause extreme discomfort.

It is an object of the present invention to provide a cold set type hair curler which produces rolls more tightly coiled at the hair ends than in the remaining length, thereby prolonging the efiectiveness of such treatment.

Another object of this invention is to provide a hair curler of this type with which a more attractive style and otherwise more desirable effect may be secured by forming at the ends of the hair tightly coiled ringlets or rolls and in the remaining hair length curls of substantially larger size.

Still another object of this invention is to provide such a hair curler which may be readily fixed in selective and adjustable positions along the hair length.

Further objects and advantages reside in novel shapes and details of construction, all of which will appear more fully in the course of the following description.

In the accompanying drawings to which the description refers like numerals are employed to designate like parts throughout the same,

. Fig. 1 is a side elevation of a curler embodying features of the present invention, partially broken for convenience in illustration and showing in dotted outline a hank or skein of hair in an initial position in the practice of the invention;

,Fig. 2 is a side elevation of the curler shown in Fig. 1, in which the dotted outline illustrates the hair roll at the completion of the operation;

.Fig. 3 is a section taken along the line 33 of Fig. 2; and

Fig. 3A is a section similar to Fig. 3, showing another embodiment of the invention in which provision is made for selective positioning of the curler along the length of the hair.

Referring to Figs. 1 and 2, the invention comprises a spool-like member S, a hair clamping 2. means or finger F hinged thereto, and slidably' mounted at one end of the member S a U-shaped locking means L.

The spool-like member S consists of a shank portion II circular in cross-section and divergent from a relatively small diameter centrally to a larger diameter at each end, and terminating in an enlarged cylindrical head portion I2 at one end and circular rim I3' of Substantially equal diameter at the other.

A means of clamping the shank I I to the skein of hair H wound thereon is provided by the finger element F, hinged to the shank II adjacent to the head I2 by means of a pin I5. The finger F has a hollow semi-cylindrical form and may include perforations as indicated by the reference numeral I6, although imperforate and various other designs will be equally operative and the illustration-in the drawings is merely for purposes of showing an operative reduction to practice. Said hinged connection permits movement of the finger F from the open position (illustrated in Fig. 1) substantially perpendicular to the shank II to a closed position (illustrated in Fig. 2) parallel to and partially enveloping the shank II. Two holes or bores I4 parallel to the axis of spool member S are provided in the head portion I2 near its periphery to serve as guides for the locking means L, which is carried slidably therein.

Said locking means L comprises a U-shaped' wire or spring formed into a cross head or connecting portion 22 and two straight and parallel legs 20, spaced in relation to each other at the same distance as the guide holes I in the shank head I2. A short end portion 23 of each of the legs 20 is bent outwardly at an angle so as to engage with the cylindrical head I2 when the locking member L is retracted, thereby prevent ing complete withdrawal, while forward movement of the locking member L is arrested by engagement of the ends 23 with the protruding shank rim I3. The legs 20 are of somewhat greater length than the spool-like member S so u that when the locking member L is in an advanced position with the end portions 23 in engagement with the rim I3 the cross head or connecting portion 22 extend from the head portion I2 sufficiently to provide a ready means of grasping for manipulation.

In the operation of the device hereinbefore described, the locking member L and the clamp or finger F are initially positioned openly as shown in Fig. 1. The ends of the hank or skein or hair, properly prepared for setting, are then wound tightly upon the slender central portion of the shank H for whatever length desired and the finger F clamped in a closed position thereon. Continuation of the winding or rolling operation secures the finger F in its closed position and, by virtue of its inclusion in the roll coils of substantially larger diameter than the initial coils are formed. When the rolling operation is completed the locking member L is advanced to a closed position, the outwardly extending ends 23 thereof serving to collect and confine the hair tightly against the spool member S and finger When the roll of hair has dried and set, the

curler is removed by retracting the locking member L and unrolling the curler suiiiciently to release the finger F and withdraw the spool-like member S from the hair roll. In repeated use of this hair curler deformation of the legs 29 of the locking member L will inevitably occur due to the strains of confining large rolls of hair against the shank H. The guide holes 54 are of such proportions and so placed as to realine the legs 20 into their original shape upon each reciprocation of the locking member L.

It is obvious that the end portion of the hair confined beneath the clamp or finger F will assume a much tighter or smaller curl corresponding to the diameter of the slender central por tion of the shank H while that portion wound externally of the finger F will assume a looser coil corresponding to the larger diameter. With hair cold set in the manner described the tighter end curls will have a longer life or durability, more nearly equal to that of the looser curls or waves in the main body of the hair, thereby promoting a greater efficiency for such cold setting treatments. Also, the tighter end curls produced by this invention are more easily concealed within end rolls and the like, while novel and attractive coiffures result from the combination of small curls and ringlets in the hair ends and loose undulations in the remaining length of the hair.

Referring next to Fig. 3A, another embodiment of my invention is illustrated comprising substantially identical elements to those previously described except that the enlarged cylindrical head L2 is carried threadedly upon an extension H of the shank H, thereby permitting rotation of the shank with respect to the locking member L, its parallel legs 28 and the head portion 12' or vice versa.

The operation of this embodiment of my invention is likewise identical with that previously described with the exception of the locking operation. When the completed roll of hair is to be locked in position against the head, it is important that the curler be secured'in such a position that the entire hair length is rolled thereon yet that no unnecessary and painful pulling or drawing of the hair from the scalp is induced. The threaded rotatable relation of the shank I! and the roll of hair H coiled thereon to the looking member L provides a means of-locking the curler in selected positions most desirable from the standpoint of comfort and utility. This is eilected by holding the spool-like member S in the desired position against the scalp, meanwhile rotating the head portion l2 into a position most suitable for advancing the locking member L. Removal of the curler from the hair upon drying, and the results attained by its use also correspond to those previously described.
