HAIR CURLER Filed Aug. 19, 1958 Dec. 13, 1960 m m f ll)? GIACOMO J. RUBINO ATTORNEY The present invention is directed to a hair curler, and more particularly to a hair curler having primary utility for curling the hair at the top of a womans head.

The necessity for practical curlers in the waving of womens hair has long been present. A wide variety of hair curlers have been developed, but to date none of them have proved to be completely satisfactory. Thus, an ideal hair curler should permit the hair to be spread evenly in respect to the curler, should not rock or pivot when placed in position on top of the head, and should be capable of furnishing as much tension as possible to the hair. Furthermore, the curler should avoid making its own impression upon the hair, but should be directed towards producing the optimum pin curl.

This invention has as an object the provision of a novel hair curler.

This invention has an another object the provision of a hair curler which efiects good distribution of the hair when used, and which provides a high degree of tension so as to form a satisfactory pin curl.

This invention has as a further object the provision of a curler which permits transmission of heat through the curler body and which avoids localized heating and concomitant injury to the hair.

Other objects will appear hereinafter.

For the purpose of illustrating the invention there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

Referring to the drawings wherein like reference characters refer to like parts:

Figure 1 is a perspective view revealing the application of the hair curler of the present invention to the hair of a user.

Figure 2 is an exploded view of the cylinder and comb of the hair curler of the present invention seen in side elevation.

Figure 3 is an exploded view similar to that of Figure 1 but showing the cylinder and comb in end elevation.

Figure 4 is a plan view of the comb of the curler of the present invention.

Referring to the drawings, the curler of the present invention comprises the cylinder 10, the comb 18, and the clamp 26.

The cylinder is formed from a helical spring 12. The helical spring 12 may be formed of metal having uniformly spaced coils, except that the coils at the ends are preferably abutting. The spring 12 is encased within the netting 14. The netting 14 is preferably formed of plastic filament disposed as a mesh, such as a diamond mesh. The netting 14 may be secured to the spring 12 by overlapping the ends of the spring and extending inwardly therefrom. As seen particularly in Figure 3 the diameter of the filaments forming the netting 14 is appreciably smaller than the diameter of the metal forming the spring 12.

States Patent 2,964,046 Patented Dec- 13, 1 960 ice The outer surface 16 of spring 12 is in the shape of a true cylinder. While the cylinder 10 may be formed from a solid cylinder which has been widely perforated, the construction shown in the drawings is to be preferred because such construction is both light in weight and provides an extensive percentage of open surface through which heat may be dissipated.

The comb 18 may be formed of metal or plastic and comprises a substantially semicircular member having teeth 20 along both of its sides. As seen from Figure 2 the length of the comb 18 is coextensive with the length of the cylinder 10. The teeth 20 should be formed so that there are a relatively large number of them per unit length, so that satisfactory even distribution of the hair in the teeth 20 of comb 18 may be achieved. The grooves intermediate the teeth 20 of comb 18 should be of sufiicient depth so that the comb 18 may achieve a satisfactory gripping action upon the hair of the user.

A series of openings 22 for the dissipation of heat are provided on the crown of comb 18 intermediate the opposed rows of teeth 20. The inner surface 24 of comb 18 should conform to the curvature of the outer surface 16 of cylinder 10. As the comb 18 is formed of web material having a uniform thickness throughout, the outer surface of the comb 18 will likewise have a curvature conforming to the curvature of the outer surface 16 of cylinder 10.

A clamp 26 is used to maintain the cylinder 10 and comb 18 in operative engagement. The clamp 26 may comprise a hobby pin or the like, one of whose legs is received within the cylinder 10 and the other of whose legs is juxtaposed to the outer surface of the comb 18.

The operation of the hair curler of the present invention is as follows:

The comb 18 is inserted into the hair at the top of the wearers head. The teeth 20 on both sides of the comb 18 grip the hair, and the hair may be uniformly distributed along the length of both of the sides of the comb 18. The cylinder 10 is then received within the comb 18, with the wearers hair disposed intermediate the cylinder 10 and the comb 18. With the wearers hair firmly anchored intermediate the comb 18 and the cylinder 10, the wearers hair is wrapped about the comb 18 and the cylinder 10 as shown in Figure 1. Since the comb 18 has a thickness dimension which is relatively small compared to the outside diameter of the cylinder 10, the eccentricity conferred upon the curl due to the thickness of the comb 18 is minimal. When the requisite curl has been achieved, the unit is clamped into firm disposition by the insertion of the clamp 26 into the cylinder 10 and over the hair of the user in the manner shown in Figure 1.

The teeth 20 of comb 18 insure that the hair is firmly gripped and evenly distributed. Moreover, the positive gripping action of the comb 18 upon the hair prevents rocking of the curler. Since human hair is always formed in varying lengths, the comb 18 permits maximum retention of short ends, a feature not readily possible with prior curlers.

The curler of the present invention permits maximum tension to be exerted upon the hair, and effects such tension uniformly. Thus, the uniform nesting of the cylinder 10 in respect to the comb 18 permits more even distribution of the tension than is possible in curlers in which the comb and cylinder are fixedly secured together at one end.

The perforated construction of the cylinder and comb permits uniform dissipation of the heat from the curler. The freely releasable clamp 26 permits the length of the curls to be closely regulated with the curler of the present invention.

The present invention may be embodied in other specific forms without departing from the spirit or esseiitial attributes" thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the inventiona I claim:
