Claims. (Cl. 132-158) This invention relates to combs and is particularly directed to hair retaining combs of the type which are worn by women to hold the hair in place, the comb being relatively unobtrusive in order to accentuate the appearance of the hair.

The primary feature of the invention is to provide a hair retaining comb which is thin, relatively light, having relatively fine teeth, and so constructed that the visible parts of the comb, which appear after the comb is inserted in the hair of the wearer are relatively thin, so as to be as unobtrusive as reasonably possible, and still perform the function for which the comb is designed.

Another feature of the comb is that the teeth thereof are thin and relatively narrow and so shaped as to grip the hair, and be held in place by the hair under ordinary usage and normal head movement.

While hair retaining combs of this general type have been available, they are generally made of a plastic material, and therefore, relatively thick and consequently present a relatively large exposed area or head, which may be objectionable under certain conditions and with certain types of hair dressings.

Due to the relatively thick material of which plastic combs of this type are generally made, the essential width and spacing of the teeth necessarily reduces the number of teeth which can be formed in a limited comb length, thereby reducing the hair gripping characteristics of the comb, and consequently the effectiveness thereof, while at the same time rendering the overall weight of the comb quite heavy.

A feature of a modification of the invention is that the upper end of the teeth of the comb and the head integral therewith, are folded over in such a manner as to form a gap or channel between the head and the adjoining surface of the teeth of the comb, to more positively grip the hair and retain the comb in place, in the hair, while at the same time enhancing the appearance of the comb, when in use, as the shallow head is clear and unobstructed.

A major feature of the comb is that it is fabricated of a relatively thin sheet metal which is heat treated and drawn or tempered in such a manner as to provide a high degree of elasticity, strength, and general flexibility.

Another feature of the comb construction is that the free ends of the teeth, which are relatively thin and therefore quite sharp, have a rounded tip of a foreign material deposited thereon, or otherwise attached thereto in order to avoid injury to the head and scalp, when the comb is inserted into the hair of the wearer.

In a modification of the comb construction, the tips are integral with the free ends of the individual teeth of the comb, the tips being formed by upsetting the end of the tooth, or by other suitable fabricating means, to an outer cross-sectional contour substantially the same as the attached tips.

A major feature of the construction is that the comb while relatively thin and light is fabricated and heat treated in such a manner that it will retain its shape,

Zen

and the spacing and relative position of the teeth thereof, even though the comb may be dropped or deformed to some extent in the process of inserting it into the hair.

Another feature is that the entire comb, including the metal head and teeth, and the tips made of a foreign material, or integral with the teeth, may readily be coated and colored in a wide range of colors and shades, thus blending the comb with the hair color, or individual taste of the wearer.

Repeated efforts have been made over a period of many years to produce a metal hair retaining comb of this eneral type, of light weight and having relatively thin narrow teeth, but due to difficulties encountered in the design and manufacture of the comb, these efforts produced no definite results.

The comb may be made of heat treated steel, an aluminum alloy, beryllium copper, a heat treatable corrosion resistant steel, or other suitable material, which may be heat treated and drawn to the required degree of hardness and elasticity.

The accompanying drawings, illustrative 'of one embodiment of the invention, and several modifications thereof, together with the description of their construction and the method of utilization thereof, will serve to clarify further objects and advantages of the invention.

It will be understood that the following description of the construction and the method of utilization of the light weight fine tooth hair retaining metal comb, is intended as explanatory of the invention and not restrictive thereof.

In the drawings, the same reference numerals designate the same parts throughout the various views, except where otherwise indicated.

One embodiment of the hair retaining comb shown in Figures 1 and 2, is fabricated of sheet steel, or other sheet metal which has been heat treated and drawn or tempered-to a spring temper or high degree of elasticity.

The comb shown in Figures 1, 2 and 3, comprises a relatively thin head 15 of concave arcuate cross-section, relative to a plane along the outer surface of the comb teeth, with a plurality of

intermediate teeth

16, 16a integral with the head and depending therefrom.

The

intermediate teeth

16, 16a, the axes of which are substantially parallel to one another are tapered from the upper end, at the junction with the head of the comb, to a relatively narrow blunt point, at the free end of each tooth.

The upper end of each pair of

teeth

16, 16a at the junction with the head 15 of the comb has a fillet 17 of substantially semi-circular or other arcurate contour formed thereon to strengthen the teeth at that point.

Each of the

intermediate teeth

16, 16a has a plurality of corrugations 18, 18a of alternately concave and convex arcuate contour formed in the upper portion thereof,

"from the junction with the head, to the free lower end 19 of each tooth. The axis through the lower end of each of the teeth between the end of the corrugations and the tip of the tooth, is substantially straight in one plane, the axis of the teeth being substantially parallel to one another and perpendicular to the head 15 of the comb in one plane. The corrugations are located in an arcuate plane following the arcuate contour of the head of the comb.

The corrugations 18, 18a of each intermediate tooth, follow the contour of the mating corrugations in the adjoining teeth, so that the spacing between adjoining teeth at each of the corrugations is substantially equal, the only variations in spacing being that due to the taper in each of the teeth, which is relatively small.

The number of corrugations, and the size and contour of the individual corrugations may be varied considerably, the corrugated portion of each of the teeth being either as shown in Figure 1, or shortened, thus increasing the length of the straight lower portion 19 of each tooth,

depending upon the requirements of a specificapplication.

As shown in Figures 3 and 4, the cross-sectional contour of each of the teeth, in a plane perpendicular to the head of the comb is also of concave arcuate form. This forms a compound curve in the overall contour of the tcomb as the orientation of the teeth follows the concave arcuate cross-section of the head of the comb, the cross-sectional contour along the longitudinal axis of each tooth also being of concave arcuate form in one lane.

p The concave arrangement of the teeth and the concave cross-section of the individual teeth follow substantially the convex contour of the head of the wearer, thus facilitating the concealing of the teeth of the comb within the hair, while it is worn, only the relatively shallow head of the comb being exposed.

The straight portion of the teeth facilitate their insertion into the hair of the wearer, the corrugations 18, 18a facilitating the gripping of the comb teeth by the hair of the wearer, thus retaining the comb in the position in which it is placed by the wearer over a sustained period, and while the head of the wearer is moved.

The end teeth 2%}, 28a which are located at both ends of the head of the comb are somewhat wider than the

intermediate teeth

16, 16a located between them.

The end teeth 20, 20a, the longitudinal axes of which are substantially parallel to the axes of the

intermediate teeth

16, 16a, are similarly tapered from the junction with the head of the comb to the free end thereof, each of the end teeth having a series of alternately concaveconvex corrugations, which follow the contour of the corrugations of the adjoining

intermediate teeth

16, 16a so that the spacing between each end tooth and the adjoining

intermediate tooth

16, 16a is substantially equal to the spacing between adjoining intermediate teeth, at the same distance from the comb head.

The arrangement of the teeth would follow the arcuate contour of the head of the comb in substantially the same manner as those shown in Figure l.

The free end of each of the teeth, including the end teeth 20, 20a and the

intermediate teeth

16, 16a has a tip 22, 22a of substantially frusto-conical cross-section fitted to the outer surface thereof and fixedly attached thereto, the extreme lower end of each of the tips, which is of substantially hemispherical form being of larger diameter than the thin upper end thereof, which surrounds the straight portion of each tooth.

The tips 22, 22a are made of a plastic, or similar material, which is molded to, deposited on, or otherwise attached to the straight free end of each tooth, the nature of the plastic composition, or the binder incorporated therewith being such as to facilitate gripping the metal of the comb tooth and forming a permanent bond between each tooth and the plastic tip attached thereto.

Instead of the plastic tips 22, shown in Figure 10, the tips may be made integral with the free ends of the straight portion of each of the

teeth

16 and 20. The integral tips, the cross-sectional contour of which is substantially the same as that shown in Figure 10 may be formed by upsetting the ends of the teeth or by other suitable fabricating means.

The tips may also be metallized, electro-deposited, .plated, or otherwise formed of a similarmaterial, or .a type of metal other than that of which the comb proper is made. With this type of tip, the size, cross-sectional contour, and the relation of the tip to the free end of each tooth is substantially the same as that shown in Figure 10.

As shown in Figure 9, each of the

intermediate teeth

16, 16a is of substantially rectangular cross-section, the corner edges of each of the teeth being rounded 23, 23a over the entire length of the tooth in order to present a smooth appearance and avoid possible injury to the scalp of the user.

In fabricating comb, the comb is blanked to substantially the form shown'in Figures 1 and 2, of sheet steel, a corrosion resistant alloy, or other type of sheet metal, which is capable of being heat treated to a spring temper or .ahigh degree of flexibility. During the stamping process, the head 15 of the comb and teeth thereof are formed to the respective cross-sectional contour shown in Figures 2 and 3.

Either before or after forming, the edges of the teeth of the comb and the edges of the head thereof are rounded and the sharp edges broken to obtain the cross-sectional contour substantially as shown in Figure 9.

The completed metal comb is heat treated to the required hardness, after which it is drawn to the required spring temper, which enables the head and the teeth of the comb to be flexed far beyond the extent encountered in normal usage, without permanently distorting them, so that they will return to their initial shape after the flexing influence is removed.

Instead of being heat treated and tempered after forming, the entire comb may be stamped of heat treated and tempered sheet material, which is heat treated and drawn to the required hardness before fabrication, provided the finish comb and the teeth thereof have the necessary strength and flexibility after forming, and provided the material used and the method of fabrication employed are such as to enable the head of the comb and the teeth thereof to maintain the arcuate contours shown in Figures 2 and 3 after forming, and during their use.

While the combs of this general arcuate contour have been made in the past, the problems of producing a comb of this type using thin sheet steel, or a similar material and formed with relatively narrow teeth, and heat treated and drawn to a spring temper, presents delicate problems not heretofore encountered due to the nature of the material used.

After the plastic tips are formed, the combs are colored by vacuum dipping or other suitable coating process, using a coating material which provides a uniform color over the metal sections of the comb and the plastic or other type of tips attached to the teeth thereof.

The comb shown in Figures 5 and 6 is substantially the same as that shown in Figures 1 and 2, except that after blanking, the head of the comb adjacent the junction with the teeth thereof, is bent over to a position substantially parallel to the outer surface of the intermediate teeth 27, 27a of the comb, thus forming a series of channels 28, 28a, between the head of the comb, and the adjacent surface of the intermediate teeth, as shown in detail in Figures 8, 11 and 12. The head 26 of the comb after bending, is substantially parallel to the adjacent surface of the teeth, thus forming a series of narrow channels 28, 28a, which grip the hair and more positively retain the comb in the hair after insertion therein. The channel between the head and the adjacent surface of the teeth of the comb continues to the end teeth at both ends of the comb. The upper end of each of the channels 28, 28a is of semi-circular or other arcuate crosssectional contour as shown in Figures 8, l1 and 12.

The arcuate contour of the inner surface of the teeth shown in Figure 6 is substantially the same as that shown in Figure 2, the head of the comb being of substantially the same arcuate contour and parallel to the outer surface of the teeth.

The intermediate teeth 27, 27a, as shown in Figure 5, are substantially the same as those shown in Figure 1, the intermediate teeth being tapered and corrugated in substantially the same manner, except for the channel formed at the upper end of the teeth, at the junction with the head 26 of the comb.

As shown in Figure 5, the upper end of each pair of teeth 27, 27a, at the junction with the head 26 of the comb, has a fillet 29 of substantially semi-circular crosssection formed thereon, in the same manner as those shown in Figure 1, the fillet serving to strengthen the teeth and enhance the appearance of the comb when the head 26 of the comb is bent over in the manner shown in Figures 5 and 8.

Except for the channel formed at the upper end of the teeth, at the junction with the head thereof, the tapered form and the corrugations of the

end teeth

30, 30a are 6 substantially the same as those shown in Figure 2, the

end teeth

30, 30a being somewhat wider than the intermediate teeth 27, 27a, shown in Figure 5.

The cross-sectional contour of the intermediate teeth 27, 27a shown in Figures 7 and 8, is of concave arcuate form substantially the same as those shown in Figures 3 and 4.

The number, size and spacing of the corrugations of the teeth shown in Figure 5 may be the same as those shown in Figure 1, or they may be increased or decreased in individual size and number and altered in contour, the length of the straight portion at the free end of each tooth being correspondingly lengthened or shortened.

The double concave curve formed by the arrangement of the teeth in one plane and the section therethrough in a plane perpendicular to the head of the comb, in Figures 5 and 8, is substantially the same as that shown in Figures 1 and 3, the teeth being oriented around a concave arcuate contour following the contour of the head of the comb in one plane, the individual teeth being of concave arcuate contour in a plane perpendicular to the plane through the head of the comb.

The lower end of each of the intermediate teeth 27, 27a and the

end teeth

30, 30a in the modified construction shown in Figures 5, 7 and 8, has a tip 22, 22a fixedly attached thereto, or deposited thereon, in the same manner as those shown in Figures 4 and 10, the cross-sectional contour of each of the tips and the method of depositing them on the ends of the individual teeth being substantially the same.

The material of which the tips 22, 22a are made and the method of applying them to the free ends of the teeth is substantially the same as those shown in Figures 1 and 3.

The cross-sectional contour of the

teeth

27, 30 is substantially the same as those shown in Figure 9, the corner edges of the individual teeth being rounded in substantially the same manner.

The comb shown in Figures 5 and 6 is fabricated in substantially the same manner as that shown in Figures 1 and 2, except that after blanking the head and the teeth, the head is bent over about the upper end of the

teeth

27, 30 to the position shown in Figures 7 and 8, to form the channels 28, 28a shown in Figures 8, 11 and 12.

The heat treatment and tempering of the material of the comb shown in Figures 5 and 6 is substantially the same as that shown in Figures 1 and 2, except that extreme care must be taken to assure a uniform arcuate contour of the folded head 26 shown in Figure 8, and to maintain a uniform channel width over the entire length of the head of the comb in order to maintain an even contour of the head and a uniform appearance-of the modified type of comb.

In a comb of this type, the material of the comb is preferably heat treated and tempered after bending the upper ends of the teeth so that the head assumes the relation shown in Figures 8 and 12 to the teeth of the comb.

Due to the relatively sharp bend at the upper end of the teeth, extreme care must be taken in heat treatment and drawing of the material in order to obtain the re quired degree of elasticity and to insure that the head of the comb and the teeth thereof maintain the crosssectional contour shown in Figures 8 and 11.

The tips 22 which are fixedly attached to the

teeth

27, 30 of the comb, shown in Figures 5 and 8, are applied in substantially the same manner as those shown in Figures 1, 2, 4 and 10, the material of which the tips are made and the method of applying them to the metal teeth remaining substantially the same.

Thus the tips may be made integral with the ends of the teeth, formed of a foreign metal or plated, or otherwise deposited on the free ends of the teeth in the manner hereinbefore described.

The comb shown in Figures 5 and 6, is coated and colored in substantially the same manner as that shown wa es in i res. 1 nd ,2 altho h re er are must be taken in coloring to insure coating of the interior of the chart nel 28 shown in Figures 8 and 11.

The extreme thinness and light weight of the combs shown in Figures 1, 2, 5 and 6 enable the comb to be used for purposes and in positions relative to the head, for which the conventional type of comb cannot be utilized, as the light weight of the comb enables it to be held in place and gripped by the hair in attitudes and head positions in which other types of combs would tend to fall out or loosen.

It will be apparent to those skilled in the art, that the present invention is not limited to the specific details described above and shown in the drawings, and that various modifications are possible in carrying out the features of the invention and the material, treatment, and

the method of utilization thereof, without departing from the spirit and scope of the aPPended claims.
