HAI'R CURLER Filed April 7, 1944 INVENTOR. BY Adoljai fieiier ATTOEA K) Patented Nov. 19, 1946 HAIR (JURLEitQ 3? Adolph Reiter, New York, N. Y.

Application April 7, 1944, Serial No. 530,011

1 Claim. 1

The invention relates to hair curlers of the type in which the hair strands to be rolled into a curl are gripped between a supporting base and a tongue and secured by suitable means in the rolled up position.

The problem to render a curler of this type properly workable seems simple; however, the numerous suggestions presented from time to time to solve the problem seemingly prove that practical compliance with the working requirements of this type of curlers has not been established as yet.

The hair curlers to which the invention relates may be listed in two groups; they are either one-piece curlers where the tongue is integral with the hair supporting base or the supporting base and the retaining tongue are separate elements.

In a curler of the first named type the above mentioned two members are hingedly connected with each other, the hinged connection being, for instance, attained by making the curler of a yieldable'resilient material, such as rubber; the disadvantage of this device is apparent as the required tight grip cannot be attained by a curler which consists of a yieldable material; the employment of resilient materials will reduce the rigidity of the curler structure which must be able to withstand comparatively heavy flexing strains developed during the curl rolling pror cedure.

To remedy this inefiiciency I have disclosed a curler construction in my co-pending U. S. patent application Ser. No. 503,585, filed September 22, 1943, now U. S. Patent No. 2,380,674, July 31, 1945, having separate base and tongue members, but made of a stiff material, the securing member consisting of a non stretchable and non elastic material.

However, in spite of many advantages re-' sulting from my former construction a sufiiciently strong grip desired for certain hair coifiures is not attainable thereby.

The same disadvantage results from the use of one-piece curlers where the base member and the tongue are hingedly connected and the tongue is permitted to swing away from the base.

Therefore, the main object of the present invention is the provision of a hair curler which in spite of utmost manufacturing simplicity affords a particularly firm and tight grip.

With these and other objects in view which will become more apparent as this specification proceeds the invention is illustrated by way of example in the attached drawing in which Fig. 1 is a plan view of one modification,

Fig. 2 is a sectional view on the line 2-2 of Fig. 1,

Fig. 3 is a plan view of a second modification.

In the drawing numeral I denominates the tubular base of my one-piece hair curler; the curler is made of a rigid material, for instance, metal, wood or plastics.

The base body carries a tongue 2. The tongue extends along the middle portion of the base member and parallel thereto for a length of about to of the total length of the base member. This tongue is produced by forming a slot 3 in the base body. Thisslot which is located on a part of the circumference of the base body I and between the same and tongue 2 has parallel walls; it is open at one end for the introduction of the hair strand.

In the modification of the invention shown in Fig. 1 the middle portion of the base body I is provided with a curved-in peripheral indentation, extending for a'length of about one third to two thirds of the base body; thereby a saddlelike shape is given to tongue 2 and to slot 3; this form of tongue and slot has proven to exert a particularly tight and firm gripping action, at the same time producing the type of the so-called double wave curl which is so greatly favored in modern coiffures.

In cases where this exceptionally tight and specific clamping effect is not considered necessary, the straight shape of the tongue shown in Fig. 3 also serves the purposes of my invention.

To secure the hair strand in its rolled up position the base I is provided at its one end with a cord 4 which carries a knot 5 near its free end, the latter being shaped to form a loop 9. A second knot I I is provided in the cord at the point where it emerges from base I; a recess is pro-,

vided in the base at this point for the reception of the knot II; the obstacle to the rolling of the curler caused by a protruding knot is hereby avoided.

An inwardly converging aperture 8 is provided in th other end of the base opening up into a circular recess and. extending intoa narrow slit I. However, any other type of securing means is also usable in connection with the instant curler.

In order to form the curl, a strand of hairis inserted into slot 3; the curler is rotated and due to the rigidity of the cooperating tongue and base and the saddle-like shape of the tongue the hair is firmly gripped and rolled into the curl under avoidance of any danger of slipping or loosening. The cord 4 is then squeezed into slit 1 and secured therein by knot 5.

Various changes may be made in the construction of my device without departing from the principle of my invention. Therefore, I do not wish to restrict myself to the details described and shown. o

I claim:

A curler comprising an elongated base member of circular cross section, a curved-in peripheral indentation in the center portion of said base member extending approximately through 4 one third of the length of the base, the two ends of said base adjacent to said indentation being shaped to form outwardly curved bulges, a tongue having th same curved-in shape as said indentation freely projecting over the same in parallel relationship thereto, said tongue being at the one end integrally united with said base, a saddle shaped slot between said tongue and said base for the introduction of the hair strands, a. curl securing cord fastened to one end of said base and a recessed seat at the other end for the reception of said cord.
