Dec. 1942- H. NATKIEL E l'AL 2 0 HAIR CURLING DEVICE Filed March 21, 1942 I INVENTORS Hamy [Ilatkiel BY Jame eldinam;

A TTOR/VEYS Patented Dec. 8, 1942 i 1 Harry Natkiel-and Jerome Feldman, New York, N. Y.

Application March 21, 1942, Serial No. 435,732 '4 Claims. 01. 132-35) This invention relates generally to hair curling devices. More particularly it relates to hair curling devices that in certain aspects havejthe attributes of a comband may be used in that capacity.

One of the objects of our invention is the provision of a hair curler which comprises a comb whose teeth are so inclined that hairs entered into the spaces therebetween will be held therein during the rotation of the comb for curl formation and will be readily released therefrom by a lateral movement of the comb. These objects we attain by an inclination of the teeth which is not less than 30 but which does not exceed 60.

The general objects of our invention include the provision of a device of the character described which is simple, effective and inexpensive.

These objects and such other objects as will hereinafter appear or be pointed out are attained inthe illustrative embodiments of our invention shown in the drawing wherein:

Figure 1 is an elevational view of one embodiment of ourinvention;

Figure 2 is a bottom plan view of the embodiment of Figure 1;

Figures 3 and 4 are sectional views on'an enlarged scale, taken respectively in the planes indicated by the lines 3-3 and 4-4 of Figure 1, looking in the direction of the arrows;

Figure 5 is a perspective view of one end portion of the device of Figure 1, showing particularly the channel running along the back thereof;

Figures 6, 7 and 8 are fragmentary viwsiliustrating the use of the device of Figured, a portion of the device being broken away in Figure 7 so as to disclose the cross-section;

Figure 9 is an elevational view of a second embodiment of our invention} Figure 10 is a bottom plan view of the device ofFigure9;and

Figure 11 is a perspective view illustrative of the useof the deviceof Figure 9.

Referring now to the drawing in detail, and first to Figures lto 5, the hair curler shown therein and designated generally by the letter A comprises a back portion shown as tapered,

and merging at its wider end into a handle 2|. Projecting outwardly from the back is a row of teeth 22, which are inclined forwardly, that is toward the narrow or remote end of the back 20. The back 20 is shown in Figure 3 to be rounded cross-section, the configuration illustrated by way of example being more or less circular. It is to be understood that this results in a configuration having rounded contours, which is desirable for purposes that will appear hereinafter, and that any suitable contours inwhich sharp corners and angles are avoided will be found satisfactory, as will be better understood as the invention proceeds.

The teeth 22 are separated by hair receiving slots 23 which are also directed toward the back at substantially the sameangle as are the teeth 22. This limited range of angles is such that after the strands of hair have been entered into the respective slots 23 of the comb as shownin Figure 6 and the ,comb then rotated about its back B to curl the hair thereabout, we attain the following: (1) The strands of hair entered in the slots will be held against slipping out of the slots during the initial rotation because of the angular relation of the walls which define the slots 22 to the direction of rotation of the comb; (2) The lateral movement of the comb from its position in Figure 7 relatively to the curledstrands of that figure, in the direction of the arrow X in Figure 8, will release the curl and the spaces 23 therebetween are of a depth many times that of the width of these spaces.

The teeth 22, and in fact all the portions of the device, are preferably free from corners and angles, the contours being rounded for that purpose, and the teeth are preferably tapered at their end portions.

At 25 is shown a groove or channel running along the back 20 .of the device, the purpose of which isto accommodate bobby pins, as will be explained hereinafter. 6

The use of the device, of Figure 1 is illustrated in Figures 6, rand 8. i V

In Figure 6- we have shown the hair curling device A of Figure 1 engaging a strand of hair L, the teeth 21 of the comb havingseparated the hair into portions which have entered the slots 22. In Figure 7 the curler A has been turned so that the free end portions of the hair L are wound around it in the form of a curl C. The

hair L will move out of the inclined slots 23. Before this is done one leg of a bobby pin, indicated in Figure 8 in broken lines at 26 may be inserted into the groove 25 of the curler A, whereby it will straddle the curl C and maintain its configuration after the curler A is withdrawn.

The back 20 is preferably of a thickness to fulfill its function of acting as a base for the curl C, while the teeth may be relatively thin, as shown in Figure 3,'whereby they will ofier less surface and consequently less friction to the hair through which they pass. For the same reason, as already mentioned, the contours of the teeth are preferably such that corners and angles are avoided.

As has already been pointed out, the inclination of the teeth 22 within the aforementioned range permits the ready release of the curl upon a lateral movement of the comb for reasons that will be obvious.

Thehandle 2| preferably approximates a circular cross-section, such as that shown in Figure 4, so that it may be twirled between the thumb and forefinger in. performing the operations illustrated in Figures 6, 7 and 8.

While the curler A may be made of any suitable or preferred material I have found that synthetic plastic materials are'admirably adapted for the economical production of curlers of the type described, because molding processes may be used by the aid of which the desired contours may be readily produced, whereas the cost of production if machining methods were resorted to would be prohibitive.

A second embodiment of shown in Figures 9, 10 and 11. In this embodiment designated as a whole by the letter B, the back is shown at 30, and the teeth, separated by slots 33, at 32. These parts are similar in contour and function to the corresponding parts of the device of Figure 1.

Means for clamping the curls formed by the curler is shown at 34 in the form of an elastic band one end of which is passed through an opening 35 at one end of the curler B, while the other end is adapted to fit removably into a notch 36 at the other end of the curler when the band 34 is stretched to a sufficient extent, whereby a curl will be clamped in place. This position of the band is indicated in broken lines in Figure 9. Knots 3! and 38 applied one at each end of the band 34 serve to hold the band in place in the opening 35 and the notch 33.

It will be observed that this embodiment may be left in place after a curl is formed, so that, i

for example, it may be worn over night, giving our invention is the curls an opportunity to set, whereas this cannot be done with the curler A which must be withdrawn after the formation of each curl and bobby pins or similar devices must be resorted to for maintaining the curl conformation.

It is further to be noted that in this second embodiment there is no counterpart to the handle 2| of the first embodiment, as this would obviously be in the way where the curler is to be left in the hair for a length of time.

The curler B is shown in use in Figure 11, in which a curl D is shown clamped between the back 30 and the band 34'.

While we have herein disclosed one illustrative embodiment of our invention and explained the manner of its use, it will be understood that our invention may be embodied in many other forms, as will be obvious to those skilled inthe art. It will further be understood that the disclosure herein is for purposes of illustration only and is not to be interpreted in a limiting sense, and that we do not limit ourselves other than as called for by the prior art and the language of the claims. I I

Having thus described our invention and illustrated its use, what we claim as new and desire to secure by Letters Patent is:
