Claims.

This invention relates to hair Waving or curling devices and particularly to a cold wave curling rod that is adapted for home use.

A large number of devices have been proposed and used to enable one to produce permanent or semi-permanent hair waves. Many of these involve spring clamp-s, elastic bands, or mechanical clamping devices that .must be precisely operated to clamp and unclamp the hair. Most of them are diflicult to apply and to remove and tend to become entangled with the hair. Some are so cumbersome that close, tight Waves are unobtainable. Others, more efficient in character, are so complicated in construction and relatively high in cost as to make them impractical for general home use.

It is the general purpose of this invention to overcome the outlined problems by providing a unitary, all plastic curling device having improved .features.of construction and operation.

More particularly it is intended to provide a hair curling or hair waving rod that can be readily and easily Operated by the person to whose hair it is to be applied without direct observation or the positioning of particular parts in alignment.

It is a further object of the invention to provide a simple, plastic, cold waving device that is economical to manufacture and simple and efl'icient in use.

A further object of the invention resides in the provision of a three-piece waving device of the character indicated in which the bail has a sw'ive'l'ingand rotating connection with the waving rod and said rod is held against rotation when in clamping relation to the bail.

More specifically, it is an object of the invention to provide a symmetrical, three-piece hair waving device comprising a curling rod, a hair securing or clamping bail securable over the rod, and a slidable collar-like member connecting the rod and bail for relative swinging and rotating movement with positive locking in any clamping position.

It is a further and specific object of the invention to provide a unitary hair curling device having a curling rod rotatable relative to a pivotally connected bail, with interengaging clutch elements associated with the rod and the bail respectively for locking the rod against rotation in whatever rotational position it is engaged by the bail for clamping hair.

An additional specific object of the invention is to provide a unitary hair curling device having a curling rod and a pivotallyconnected clamping bail or loop in which the bail is formed with a resilient latch member and the rod is provided with a cooperating detent.

A still further specific object is to provide a hair curling device of the character indicated having .a curling 0r winding rod with notched rib portions intermediate its ends. for positive gripping action.

These and other features of novelty and improvement contributing to efliciency in use and economy in manufacture will be more fully understood from the following detailed description of a preferred embodiment taken in connection with the accompanying drawings in which:

Fig. 1 is a side elevation to enlarged scale showing the curling device .in closed or clamping position;

Fig. 2 is a similar side elevational view showing the curling device in a completely open position;

Fig. 3 is an end elevational view of the device as shown in Fig. 1;

Fig. 4 is a longitudinal sectional view to an enlarged scale showing details of the collar-like member;

Fig. 5 is an end view of the collar-like member of Fig. 4 as seen from one end;

Fig. 6 is a partial side elevation to enlarged scale showing the clutch or locking end of the rod member; and

Fig. '7 is an end elevational View of Fig. 6.

While it is preferred to manufacture the curling device from commercially available synthetic resinous or plastic material that will withstand the chemicals used forhair waving and can be readily molded, there are various other less advantageous materials that can be employed within the purview of the invention.

In the drawings the curling device in its entirety is designated by the reference numeral Ill. As shown best in Fig. 1 the device Ill comprises a curling rod or elongated member [2, a bai1 or loop member l'4 having outwardly bowed legs and adapted to extend over and embrace the rod [2, and a thimble or collar-like member I6 formaintaining the rod and bail in assembled relation while accommodating the intended operations.

It will be seen from Fig. 4 that the thimble or cap member is is formed to provide small diametrically opposed openings I8 adjacent the open end thereof. The ends of the bail or 100p member M are formed to provide aligned pivot shafts 29 fitting into the thimble openings I8 for ea y rotation (Figs. 1 and 2). At their inner extremities the bail shafts 20 when assembled have a button formation 2| which is preferably rounded for purposes that will be described.

The other end of the bail I4 is formed with an outwardly directed finger tab portion 22 and an inwardly directed catch loop 24 as shown in Fig. 1. In order to give the catch loop 24 greater resiliency or springiness than is provided by the slightly bowed portions of the bail I4, an opening or cutout 26 is disposed between the tab portion 22 and the catch loop. Fig. 2 indicates the formation and arrangement of a catch socket v 28 in the free end of the rod I2 for cooperative engagement with the catch loop 24 when the device is in the closed condition illustrated by Fig. 1.

While the rod I2 may have a variety of shapes it is preferred to form it with a plurality of spaced longitudinal ribs 30 extending the length thereof for better frictional engagement and gripping of the hair which is curled thereon. Because the hair curled on a rod like this is always of maximum diameter at the center and in order to maintain the hair centrally of the rod, the rod I 2 of this invention is shaped to provide a relatively thin central portion tapering outwardly to thicker ends. In the cold waving proc-' ess the end of each divided portion of hair to be waved has to be enclosed in the fold of a thin end paper or tissue. It has been found that the difficulty of starting the paper enclosed hair around the rod can be effectively avoided by forming each rib 30 with a longitudinal series of small V-shaped notches 3| extending at least over a major intermediate portion, as shown in Figs. 1 and 2.

Figs. 1, 2 and 6 show the formation of the rod !2 to include a cylindrical clutching end 32 having longitudinally extending outwardly directed clutch teeth 34, the ends of which may be rounded as shown. The clutching end 32 is spaced from the main portion of the rod I2 by a connecting shaft 35 of reduced diameter. This results in a groove formation, preferably of V shape, between the clutching end 32 and the remaining portion of the rod I2.

Figs. 1, 2, 4 and clearly illustrate the formation of the thimble or cap member It to provide a cooperating clutch element. In the preferred embodiment this second clutch element comprises a plurality of longitudinally extending jaw teeth 40 projecting a short distance inwardly from the closed end 42 of the thimble I5, these teeth 40 being so spaced and dimensioned as to cooperate with the teeth 34 on the clutching end of the, rod I2. are also shown as rounded for easier meshing.

From Figs. 1 and 2 it will be apparent that the thimble I 6 can be moved longitudinally relative to the rod I 2 for an appreciable distance that is sufficient to permit engagement and complete disengagement of the teeth 34 and 40 of the respective clutch elements. The outer part of the annular groove formation 38 is suificiently wide to accommodate such movement, which is limited by engagement of the rounded retaining forma- The ends of the clutch teeth 411 tions 2I with one side or the other of said grooved formation. When the clutch elements are in the disengaged relation shown in Fig. 2 the rod I2 can be freely rotated and the rounded formation of the buttons 2| minimizes the friction of the engagement with the grooved formation 38. When the teeth 34 and 40 of the respective clutch elements are in full engagement as shown in Fig. 1, the rod I2 will be locked against rotation in either direction and the catch loop 24 of the bail hi can be snapped into the rod socket 28 to maintain all parts of the curling device III in fixed curling relation. The thimble member I6 is of a length to extend completely over the portion of reduced diameter (36-38) when the teeth 3 and 40 are interengaged. The cap member I6 having teeth 40 within its closed end encloses the teeth 34 on the adjacent end of rod I2 at all times.

It is believed that the unusual advantages of the cold wave curling device of this invention motion of both the rod I2 and the bail [4 permit the rod to be manipulated very easily and the hair wound to a tight position adjacent the scalp. The bail I4 can remain at rest in a removed position Where there is no likelihood of its becoming entangled in the hair while it is serving also as a support and bearing for the connected end of the finding rod I2. Upon completion of winding the bail I4 is merely swung into clamping position over opposite sides of the curl of hair and securely latched to the end of the rod I2 by the strong but yielding engagement between the catch loop 24 and rod socket formation 28. It is of course unnecessary to rotate the bail I4 in making this clamping connection as the clutch teeth 34 and 40 will engage and lock in any rotational position of the bail without the necessity for aligning or locating any parts of the device. The curling device of this invention also permits quick andeasy removal from the hair without tangling after the wave is completed. It is necessary only tov unfasten the bail.

I4 and. swing it to a removed position with respect to the rod I2 such that the clutch elements will be unlocked and the rod can freely unroll the hair without interference or catching.

While a preferred embodiment of the curling device of this invention has been fully illustrated and described, it will be appreciated by those skilled in the art that various changes can be made in the details of construction and form and arrangement of parts without departing from the spirit of the invention an the scope of the appended claims.
