HAIR CURLER DEVICE Filed June 7, 1956 17 /6 BeF/ Q fl P ATTORNEY HAIR CURLER DEVICE Bernard Fischer, Jamaica, N. Y.

Application June 7, 1956, Serial No. 589,908 4 Claims. (Cl. 132-43) The present invention relates to a hair curler device and it particularly relates to a hair curler device for giving either permanent or temporary wave to womens hair.

It is among the objects of the present invention to provide an inexpensive, lightweight, durable, effective hair curler device which may be readily used by women for achieving either permanent or temporary hair wave styling, and which will be relatively light, readily applied, sanitary and durable.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by Way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects, it has been found most satisfactory according to one embodiment of the present invention to provide a hair curling device in which there is provided a rather thick tubular mass of polyurethane sponge.

The sponge mass is preferably of a cylindrical form with a central bore or opening therethrough which will receive a plastic covered aluminum or noncorrosive metal strip. 7

The polyurethane sponge may be replaced by other synthetic or resinous or plastic sponge which may be readily compressed but will readily spring back to their original shape when the pressure is released.

It has been found most satisfactory to provide the sponge so that it will have a porosity or open pore structure equivalent of about 75 to 90% of the total volume and preferably extending up to 85 and 90% of the total volume, with the pores being of the non-communicating type so that any liquid or treating chemical would only saturate the outer layer of the pores with the inner pores being substantially free of any liquid which may soak into the pores in the outer portion of the tubular sponge.

Furthermore, it has been found that the .pores should be of a predetermined range to give the desired flexibility and crushability. The preferred pore size should be less ted States Patent" than of an inch and desirably between and V of an inch with the pores desirably all being graded so that they will be approximately within the same range of sizes.

The flat bendable yet relatively stiff wire member desirably is inserted within the sponge in such a way that the side edges will have a friction grip in a bore periphery longitudinally in the central axis of the sponge.

In an alternative form, a stiff plastic tube with outer serrated edges may be provided to grip within the bore of the tubular sponge While the plastic coated still flat wire is held within such serrated or grooved tubular member.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings,

Patented June 10, 1958 curler devices of Fig. 1 showing the central plastic coated flat Wire members in position.

Fig. 3 is a transverse sectional view taken upon the line 3-3 of Fig. 2.

Fig. 4 is a transverse longitudinal sectional view similar to Fig. 2 of an alternative embodiment.

Fig. 5 is a transverse sectional view upon the line 5-5 of Fig. 4.

Referring to Fig. 1 there is shown a feminine head A wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Fig. 1 is a perspective view of the head of a user showing how the novel curling device of the present application may be utilized.

Fig. 2 is a longitudinal sectional view of one of the with hair B and with the curlers C, D and E in position. These curlers C, D and B have the inwardly bent wires F, G and H to hold the curl in position and to hold the curler in position upon the strand of hair. The curler-s themselves are best shown in Figs. 2 to 5.

In the first embodiments of Figs. 2 and 3 there is shown a fiat plastic coated wire I which is encircled by, the tubular polyurethane or other synthetic, resinous or plastic sponge K.

The sponge has an outer cylindrical contour at It), the straight or transversely cut end and edge faces 11 and the central bore 12.

The bore 12 gives the sponge K-a tubular shape and the side edges of the plastic covered wire I, as indicated at 13, will contact the side edges of the bore.

The upturned ends 14 may be turned over to grip the coil of hair and hold the curler in position as indicated in Fig. 1 at F, G and H.

In the form shown in Fig. 4 the tubular polyurethane sponge member M has a serrated or grooved insert tube L and an insert wire N.

In the embodiment of Figs. 4 and 5 the tube L will be held in position firmly as indicated at 15 by reason of its grooves or serrations 16;

The central portion 17 of the wire N may be inserted through and may slide freely within the tube L and the end 18 may be folded over as indicated at F, G and H in Fig. 1.

It is thus apparent that the applicant has provided a relatively simple, durable curler device having side applications to either temporary or permanent hair waving or to hot or cold waves and which is sanitary, readily handled and manipulated and of light weight. An effective hair wave may be quickly achieved.

While there has been herein illustrated and described the preferred embodiment of the invention, it is to be understood that applicant does not limit himself to the precise construction herein disclosed, and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having now particularly described and ascertained the nature of the invention, and in what manner the same is to be performed, what is claimed is:

1. A hair waving device comprising a tubular synthetic sponge having longitudinally and axially extending therethrough a plastic coated flexible bendable flat metal rod, said sponge also receiving a central stiff plastic tube having an outside roughened surface to hold it in position in the center of the tubular sponge and said tube encircling and tightly holding the central portion of said bendable rod.

2. A hair waving device comprising a tubular synthetic sponge having longitudinally and axially extending therethrough a plastic coated flexible bendable flat metal rod, said sponge being a polyurethane sponge, said sponge also receiving a central stifi plastic tube having an out side roughened surface to, hold it in position in the center of the tubular sponge and said tube encircling and tightly holding the'central portion of said bendable rod.

3. A hair Waving device comprising a tubular synthetic sponge having longitudinally and axially extending therethrough a plastic coated flexible bendable fiat metal rod, said metal rod consisting of thin flat aluminum, said sponge also receiving a central stiff plastic tube having an outside roughened surface to hold it in position in the center of the tubular sponge and said tube encircling and tightly holding the central portion of said bendable rod.

4. A hair waving device comprising a tubular synthetic sponge having longitudinally and axially extending therethrough a plastic coated flexible bendable flat metal rod, said sponge having a central stifi plastic tube, and said tube having an outer roughened face so that it will grip itself in position within the tubular sponge.
