2 Claims.

This invention relates to hair curlersv of, the type wherein the-hair isdried by air contact. Curlers of this type. are often applied to the hair while the hair is moist. and. removed when. the hairis dry. As this takes considerable time, even when artificial drying means. are. utilized, itjis desirable to provide a. curler whichewill' allow as rapid. dryingv of the hair coiled. thereon as is possible.

Due to, the nature of. human hair and. its tendency to split and crack when subjected. to mechanical abuse, asby. being kept tightly coiled and moist over too long a period, or by being nicked or scratched by sharp edges or corners. on the conventional type of hair. curlers, it. is. also desirable to-provide a curler which wil1 minimize such cracking or splitting.

Curlers which are in the form of cylinders having. perforations-therein have atendency to catch the hair of the innermost layer wound thereon, so that when. the curler is removed by sliding it axially of the curlthe innermost layer tends to stick to the curler and thus pull out of the, interior of the curl, the result beingv that the configuration of the curl is spoiled.

It'is, therefore, afurther object of thisinvention to provide'a curler in which the inner. layer of hair does not separate from the outer layers during removal from. the curl.

It is a further object of this invention to pro- .vide a curler which exposes a relatively large amount: of hair to the circulation of air.

It is a further object of this invention to provide a. curler in which. the coil of hair thereon has a substantial portion of its inner surface ex.- posed to circulation of air.

It is a further object of this. invention. to'provide a curler which obtains the above advantages and at the same time causes a minimum of discomfort to the wearer.

It is a further object of this invention to provide a curler which may be readily removed from the curl.

It is a further object of this invention to provide a curler of resilient construction which is characterized by the above objects.

This invention possesses many other advantages and has other objects which may be made more easily apparent from a consideration of several embodiments of the invention. For this purpose there are shown a few forms in the drawing accompanying and forming part of the present specification. These forms will now be described in detail, illustrating the general principles of this invention; but it is to be understood thatthis'detailjed description is not to be taken in a.limiting sense, since the scope of the invention is;;best"defined by the appended claims.

Referring to. the drawing? 7 Figure I"shows' acurler embodying the present invention, with; the clamp in open position;

Figure 6 is. anenlarged transverse section taken on..lin'e Yu -Bibi. Figure 5.

The curlershown'in Figures 1 to 3 consists of a body member I ll and, a clamp member H pivoted. together. This is to allow the clamp member. tobe pivoted to. aposition engaging the coil of. hair on thebody. member in. a.manner wellunderstoodin the art. The body member IOIis preferably formed. of resilient material. such as. rubber or. the like andhas longitudinal grooves I.2.therein, thus formingridges I 3. Theseridges have. been-showmashaving a rather small area in contact with the. hair Hi wound upon the body of the curler It hasbeenfou-nd-that when the body. is made of rubber or some similar material the friction between the .body of the curler and the hairvhas a tendency to causedisarrangement of the curlas the curleris removed by axial movement. The use of ridges having a comparatively small surfaceimcontact with the hair wound on the bodyv of; the I curler; decreases the likelihood of suchdisarrangement as the curler is removed.

If desired, the. body portion Ill maybe formed by any. well known extrusion process. It is not, absolutely necessary that the body portion H) be formed of resilient material, a rigid material such as aluminum or any of the numerous rigid plastics may be employed, although resilient material is preferred for reasons which will presently appear. The body portion H! has a longitudinal bore [4 formed therein and a plurality of holes or openings l5 extending through the walls of the body portion It) to the exterior thereof. As

shown in Figure 3, these holes or openings are present only in the valleys of the grooves in the body. This is because it has been found that the holes or openings if present in portions engaged by the hair of the user have a tendency to cause splitting thereof, and further these holes as mentioned above have a tendency to catch the hair wound over them and cause the curl to pull out of shape when the curler is removed. By providing the holes or openings [5 in the valleys of the grooves l2 they will be clear of hair wound on the body II] as shown in Figure 3 and thus will not cause such splitting, cracking, or disarrangement of the curl upon removal of the curler. At the same time, placing the openings I5 in the bottom of the grooves I2 prevents the hair wound upon the body portion In from closing the openings and thus preventing circulation except through a very small restricted portion of the hair. It will be noted that the grooves extend the entire length of the body portion Ill. With this construction there is no possibility of hair blocking circulation along the grooves and thus an increased drying rate is obtained by reason of this circulation under all conditions of use.

The clamp member Il may be formed of a piece of wire having a sinuous portion lfi intended to engage the body portion III. This sinuous portion [6 is intended to enter one end of the bore M of the body NJ. The end of the clamp member which is pivoted to the body l may be secured thereto in any suitable manner. In the form shown in Figure 2 the ends of the clamp are formed with offset portions Il passing through the walls of the body member ID and secured therein. These ofiset portions 11 engage the inner surface of the bore of the body member and thus prevent the withdrawal of the ends of the clamp member from the body member. If the body member be made of resilient material, thes offset portions engaging the inner walls of the bore will tend to resiliently hold the legs of the clamp member in providing a lacquer coating or the like to prevent rust from affecting the hair on the curler.

If the body of the curler is formed of rigid material, it may have a cross-section similar to that shown in Figure 4. Such a body member may be extruded or drawn in the shape shown, or may b formed by rolling grooves l2 into a cylindrical tube, to give it the cross-section shown. This form may also have openings [5 communicating between the bottoms of the grooves l2 and the hollow interior I4 of the body member.

Figures 5 and 6 show a further form or modification of this invention. The characteristic which diiferentiates this form from that of Figure l is the lack of a central bore. When this bore is omitted the grooves 20 in the body memher 2! may be considerably deeper as shown by comparing Figures 3 and 6, which allows a greater circulation of air along the length of the grooves. Of course, the holes l5 are absent in this form as there is no central bore to which they may be connected. The form of pivot connection between the clamp 22 and the body 21 cannot be as shown in Figure 2 but will necessarily be simply a right-angled bend on each leg of the clamp member 22. It may be necessary to employ considerably heavier wire with this form in order that the clamp may be securely held in place. In order to provide a recess for the portion 23 of the clamp member a place. It has been found that when an attempt is made to close the clamp member over too large a coil of hair wound upon the body member, the legs of the clamp tend to spring out of place. On the other hand, when the resilient side walls of the body member are employed of the body Ill the same operation can be performed by bending the body portion I0 so that the portion I6 may be inserted in the bore. In fact, it is not even necessary that the clamp member be formed of wire or other resilient material and it could be readily formed of a single piece of plastic or thelike, considerablylarger in cross-section but having the same functions as a wire clamp member would have. The use of such plastic material avoids the necessity of depression 24 has been indicated in the free end of the body member to serve the function of the bore [4 in retaining the clamp member in place.

The grooves 20 extend entirely along the body It, thereby permitting the free circulation of air underneath the coil of hair on the curler.

I claim:

1. In a hair curling device, an elongated body member adapted to receive hair wound thereon, said member having a plurality of concavities in its periphery extending along its entire length, whereby to permit circulation through said concavities and on the inner side of a coil of hair wound thereon. I

2. In a hair curling device, an elongated body member adapted to receive hair wound thereon,

said member having a plurality of concavities in its periphery extending along its entire length, said member having a bore extending through its entire length, and a plurality of openings extending transversely of the length of the body member from the bottom of said concavities to th bore, whereby the edges of said openings are out of contact with hair wound upon the body member and air is free to circulate through the bore and the concavities.
