United States Patent 3,491,774 HAIR GROOMING DEVICE Anthony Carbone, 2320 W. Greenleaf Ave., Chicago, Ill. 60645 Filed July 13, 1967, Ser. No. 653,182 Int. Cl. A45d 4/06, 6/00, 1/04 U.S. Cl. 1329 10 Claims ABSTRACT OF THE DISCLOSURE A hair grooming device for professional and home use which includes a power-driven porous drum through which heated air is discharged. The frictional porous outer surface of the drum engages and tensions hair as the drum rotates and the simultaneous application of heat to the hair through the heated drum grooms and trains the hair.
Background of the invention Rotary power-driven hair brushes have been known in the past although such devices have not been widely accepted, either for professional use or for home use, because they provide slight (if any) advantage over more conventional hair brushes. Whether power operated or not, brushes mainly perform the function of brushing, pulling, and combing the hair in one direction. The application of power, as in a rotary brush, does not alter this function and, in some cases, creates problems not seriously encountered when conventional non-power operated brushes are used. For example, long hair, if caught by a rotary power-driven brush, may become wrapped and tangled about the device, thereby defeating the purpose of the brushing operation and, at least in some instances, causing considerable discomfort and inconvenience for the user.
The elfects of heat in the styling and grooming of hair are also well known. In recent years heated combs have been used as an aid to the styling of hair. Also, it has long been a common practice to use hair dryers which direct heated air against hair which is temporarily held in place by suitable hair curling devices, netting, and the like. While such heating devices are useful in the styling of hair, their use is highly specialized and, in general, they are not well suited for use in barbershops or at home for the styling and grooming of mens hair.
Description of the invention One aspect of this invention lies in recognizing that hair, particularly mens hair, may be effectively groomed and styled if streams of heated air are directed against the hair as it is tensioned. Unruly hair, if simultaneously tensioned and heated, will lie properly in place if the tensioning force is exerted in the proper direction.
A further aspect of the invention lies in the discovery that a tensioning force of proper intensity and direction may be readily applied to hair by means of a rotating drum having a friction-producing surface. The friction-producing surface is porous so that heated air may be discharged through the wall of the drum and will impinge on the hair tensioned by the rotating drum,
The device includes a housing which may be easily held in one hand and which preferably contains both an electric motor and electric heating means. Air drawn into the housing flows over and about the motor and may be at least partially heated thereby. In the preferred form of the invention, the air also is directed over and about the electric means, such means serving to increase the temperature of the air to a level suitable for most effective application to the hair of a user. The heated air is forced from the housing into a drum rotated by the electric motor, the hollow drum having a porous wall for 3,491,774 Patented Jan. 27, 1970 ice the radial discharge of the heated air. The drum may be formed of a selected material so that its outer surface has the frictional properties capable of tensioning hair but, most desirably, the drum is covered by a replaceable porous sleeve formed of silk, perforated leather, or some other material which provides a friction-producing surface. During operation, the drum and sleeve become heated by the air passing therethrough and, therefore, hair is heated not only by the outwardly flowing air but also by direct contact with the heated drum and sleeve.
Drawings Referring to the drawings:
FIGURE 1 is a perspective view of a hair grooming device embodying the invention;
FIGURE 2 is a longitudinal sectional View of the device;
FIGURE 3 is a transverse sectional view taken along line 33 of FIGURE 2.
Description of drawings In the embodiment of the invention illustrated in the drawings, the numeral 10 generally designates a hair grooming device having a housing or casing 11 and a. drum assembly 12. The housing defines a chamber 13 which contains an electric motor 14, a circulating fan 15, and electric heating means 16. The motor shaft extends outwardly beyond one end of the housing and is connected to one end of the hollow drum 12.
A handle 18 is provided by the housing so that the entire unit may be easily held by one hand of a user. In the illustration given, the handle is formed integrally with the housing and the entire housing is formed of a rigid plastic material such as, for example, polystyrene. It is to be understood, however, that the housing may be formed of metal, or may be formed of a combination of metal and plastic to utilize the heat-insulating properties of plastic.
The rear end cap 19 of the housing is provided with a plurality of air intake Openings 20. The motor 14 is mounted within thecasing adjacent the openings and is cooled by the inflowing air. The air is in turn heated by the motor and, after passing forwardly about the motor, passes about and through the heating means 16. In the illustration given, the heating means consists simply of an electric heating coil which is concentric with motor shaft 17. The forward movement of air results from the operation of impeller 15 which is mounted upon the motor shaft, preferably between the motor and the heating means.
The heated air is discharged from the housing 11 through an enlarged opening 21 in the housings front end. A bearing element 22 is secured within opening 21 and is provided with a central hub 23 which rotatably supports the forward end portion of shaft 17. Large arcuate openings 24 between the hub 23 and the annular peripheral portion 25 of the bearing permit the unobstructed forward flow of heated air from the housing. As shown most clearly in FIGURE 3, the hub 23 is supported by radial portions 26 which extend between the hub and the annular portion of the bearing and which may be formed integrally with the remainder of the bearing element.
Drum 12 may be formed of any suitable material although metal is preferred because of its heat-conductive properties. In the illustration given, the drum is generally cylindrical in shape so that upon rotation the drum has a uniform peripheral speed. However, in some instances it may be desirable to taper the drum forwardly to a slight extent, one purpose of the taper being to insure a tight non-slipping interfit between the drum and its cover 27.
As shown most clearly in FIGURE 2, the drum is provided with a multiplicity of small openings 28 in its cylindrical wall 29. At one end, the drum is provided with a concentric hollow neck portion 30 which is provided with means 31 for securely attaching the drum to the end of motor shaft 17. In the embodiment illustrated in the drawings, such means comprises a bearing similar in construction to bearing element 22, the peripheral portion 32 of bearing 31 being securely anchored to the neck portion 30 of the drum and the central portion 33 of the bearing being rigidly secured to shaft 17. Openings 34 in element 31 provide for the passage of heated air into the interior of drum 12 from housing 11.
End wall 35 of the drum is imperforate and the enlarged opening of neck portion 30 of the drum communicates directly with opening 21 of the housing. Thus, air heated within the housing and driven forwardly by impeller is discharged only through the peripheral openings 28 in the drums cylindrical wall 29. The sleeve 27 which is tightly fitted about the drums cylindrical surface is porous in nature so that the heated air may readily pass therethrough. The sleeve may be formed from any of a wide variety of materials which provide a surface capable of frictionally engaging and tensioning human hair as the drum rotates. I have found that finely knitted or woven fabrics of silk or nylon are particularly effective but fabrics formed from other fibers having similar properties may also be used. Furthermore, perforated leather, particularly with the suede side exposed, is also suitable, as would be plastic materials which simulate the texture and properties of leather. Finally, the sleeve, or the drum itself in the absence of such a sleeve, may be provided with a multiplicity of small projections or bristles which, because of their shortness, serve to increase frictional resistance and promote the hair-tensioning effect rather than to brush through the hair in the manner of a conventional brush.
Housing 11 is provided with a suitable switch 37 for controlling operation of the motor and heating means. In FIGURE 2, the switch is shown mounted in end wall 19 of the housing and the electric cord 38 for the electric elements of the unit also extends through end wall 19, being supported therein by a resilient bushing 40.
Operation In operation, the friction sleeve 27 of the rotating drum is simply urged into contact with the hair, the direction of the drums rotation in the area of contact corresponding with the direction in which the hair is to be styled or trained. As the friction sleeve engages the hair, the hair is tensioned and straightened. At the same time, heat is transmitted to the hair through the heated drum by reason of the direct contact between the hair and the sleeve and by reason of the outwardly flowing heated air. It has been found that the heated air is of particular importance -in causing the hair to retain the position into which it has been tensioned by the rotating drum.
The sleeve may be retained upon the drum by any suitable means. If the sleeve is to be permanently secured to the drum, then a suitable adhesive might be used. I have found, however, that where the sleeve is formed of a stretchable material, as for example a knitted or woven fabric, and where the sleeve in an untensioned state has a smaller internal diameter than the outside diameter of the drum, a secure frictional interfit between the sleeve and drum will occur and will obviate the necessity of any additional attaching means. In normal use, slippage between the drum and sleeve will not occur and yet removal of the sleeve will be simple enough so that such a sleeve may be removed and replaced by a clean sleeve whenever such a change is desired.
