E R R u c F M HAIR CURLING DEVICE Filed July 21, 1947 Patented Feb. 21 1 950 UNITED STATES PATENT OFFICE HAIR CURLING DEVICE Margaret F. Currie, Manhasset, N. Y.

Application July 21, 1947, Serial No. 762,427

This invention relates to improvements in hair curling devices of the type in which the hair to be curled is held under compression against a base by means of foldable members.

One object of the invention is to provide a unitary hair curler which can be readily used by persons inexperienced in hair dressing.

Another object of the invention is to provide a simple compression fastening which can be relied upon not to release the hair from compression by slipping, loosening or otherwise.

I have found that durable, flat curls of the desired type are best obtained when the hair is wound tightly about a central supporting member or winding column of generally cylindrical shape, and held tightly in that position by clamping means compressing the hair against a base extending outwardly from the column. The clamping means should have a plurality of points of engagement with the base so as to hold the hair firml and uniformly.

A further object of my invention is to utilize the setting properties of thermoplastic materials to secure the clamping members in position on the device, thereby simplifying the manufacture.

Other objects and advantages of the invention will be apparent from the following description and the drawing, in which:

Fig. 1 is a side elevation of a preferred form of the improved hair curler;

Fig. 2 is a perspective view of the device of Fig. 1, showing the clamping members in position about a strand of hair;

Fig. 3 is a view similar to Fig. 2, but showing an alternative method of locking the hair in position;

Fig. 4 is a perspective view of a modified form of the invention, in which the hair winding colunvn is flared instead of cylindrical;

Fig. 5 is a side elevation of a form of the invention in which the clamping members are held in position within a mass of plastic material; and

Fig. 6 is a side elevation of a form of the invention in which the clamping members are secured to the base of the device rather than to the winding column and in which the base is circular (without serrations or the like).

Referring first to Figs. 1 and 2, reference numeral I denotes a base preferably having a substantial number of scallops, serrations, or the like indicated by numeral 2. The number of serrations may vary. The four shown are satis- 5 Claims. (Cl. 132-40) factory but a larger number, as in a knurled disk, is very good. 1

Secured to the base I, either integrally'or by any preferred method of attachment, is ,a wind column 3 arranged about in the center of the base. The size of the device will vary according to re quirements but in general it is preferred to use a base having a diameter about one-half to three fourth inch.

Clamping

members

4 and 5, 6 and 1, are secured to the device as by insertion in holes 8 and 9 passing through winding column 3. The clamping members 'will be referred to herein as wires, but they may be flexible strips or theflike. It is preferable to. make all parts of .the device from materials which will not be affected by lotions or other treating compositions applied to the air. Metals (especially the light metals such as aluminum), rubber, plastics, etc., are suitable for the base and winding column. The clamping members are 'best made of wire durable under repeated bending and either inert to the usual hair dressing compositions or protected from them by wrapping or coating.

A convenient method of inserting the wires is to run a single strand through holes 8 and 9, respectively, the free ends of the strand being tied, soldered, or otherwise secured together to form a loop. The length of wire is sufficient to enable it to be crimped conveniently under base I, as shown in Fig. 2. Engagement of the two branches of each loop 4 and 5, B and I, with indentations in the circumference of base I formed by serrations 2, effects a very positive and secure clamping action. I prefer this configuration of the base, though other shapes are suitable.

Referring to Fig. 3, this illustrates another method of locking the clamping members over the hair to be curled. The loop denoted by 6 and I is passed through the loop denoted by 4 and 5. The loops are drawn down tightly over the coiled hair and looked over the margin of base I.

Fig. 4 shows a form of the invention in which a winding column II has a flared lower portion in which holes 13 and I4 are made for the entry of the clamping wires.

Fig. 5 shows a curler according to my invention made integrally from thermoplastic material or equivalent plastic. It has base |3a and winding column Ma. Clamping wire loops I5 and [6 are inserted in the material while still plastic and are secured in place by solidification.

of the plastic.

8 and 1, are then bent outwardly and drawn tightly under the base I, fitting into the indentations formed by serrations 2, as shown in Fig. 2. After the hair has been allowed to stay under compression for the desired time, the loops are bent back into their original'position and the curler is removed from the head. It will be noted that the wires are mounted within the body of the wh r in co umn so' hat t e a e no a swer points cg attachment which might catch the hair an eri q scomior ny s it le e o .tion may be used with thehair curler. An important advantage of the invention is that the hair dri readily, for it is not shut off from contact with the atmosphere, although held y'by thelsuperposed clamping means.

The operation of the device of Fig. 3 is the same as that of Figs. 1 and 2, except that one 02 s drawn. thrq sh the. oth r o d the lam accen- "T ed' v l bf.

1. A hair curling device comprising a base, a

column a continuous cylindrical surface extending upwardly from said base for a substantial distance and adapted to support hair wound thereabout, and hair-retaining means comprising narrow pliable non-resilient members attached to the device and bendable over the hair wound on the column, said means overlying a minor portion only of the area of the hair being treated.

2. Invention according to claim 1, in which the hair-retaining means are loops of wire secured to the column.

3. Invention according to claim 1, in which the column has a plurality of small openings in which the pliable non-resilient members engage.

4. A hair curling device comprising a base and a column having a continuous cylindrical surface arising from the base for a substantial distance, said base and column being adapted to receive hair to be curled, and pliable wires secured to the column and bendable around the hair to hold it in position on the base.

5. Invention according to, claim 4;, in which the base and column are unitary. he column has perforations, and the wires are in the form of loops which are passed through the per! forations.
