United States Patent H SELF-CLEANING HAIR BRUSHES Jean P. Du Bois, 4660 Dobson St., Skokie, Ill. Filed Dec. 14, 1962, Ser. No. 244,624 1 Claim. (Cl. 15-160) The present invention relates to self-cleaning hair brushes, and is particularly concerned with hair brushes adapted to be cleaned by subjecting the brush to a stream of high pressure water from the ordinary water faucet of the city supply.

One of the objects of the invention is the provision of an improved hair brush which has its bristles mounted in a plurality of lonigtudinally extending bristle-supporting members spaced from each other sufficiently to permit the water supplied by any water faucet to flush through the brush along the bristles, carrying away all the hair and other foreign material which might be carried by the bristles.

Another object is the provision of an improved hair brush in which the bristle-supporting members are spaced from each other and made elliptical in cross section or streamlined to permit the easier and unimpeded access of the water stream to the bristles to remove the hair and other foreign material and effect a quick cleaning of the hair brush.

Another object is the provision of a plurality of improved modifications, including the mounting of the bristles upon a plurality of plugs which may be inserted in preformed apertures in which, when the plug with its head has been passed through the aperture, the head expands outside the top of the brush and automatically secures the plugs and bristles to the brush body.

Another object of the invention is the provision of an improved brush provided with extruded conical bristles which are peculiarly adapted to be employed for massaging the scalp.

Another object is the provision of improved hair brushes which are simple in construction, which have a minimum number of parts, which may be economically manufactured, and which may be easily cleaned.

Other objects and advantages of the invention will be apparent from the following description and the accompanying drawings, in which similar characters of reference indicate similar parts throughout the several views.

FIG. 16 is a sectional view taken on the plane of the line 1616 of FIG. 15, looking in the direction of the arrows.

Referring to FIGS. 1-6, 21 indicates in its entirety a. hair brush embodying the invention. The brush comprises a plastic frame 21 having a longitudinally extending handle 22; and the frame 21 has a plurality of longitudinally extending bristle-supporting

members

23, 24, 25, 26, 27, 28, 29.

The bristle-supporting members are carried by and integrally joined to the

end frame members

30, 31; and the entire frame may be molded out of a suitable plastic, such as plastic resin, for example. The bristle-supporting members 23-29 are preferably elliptical in shape, having a pointed upper edge 32 and a blunt lower face 33, the lower face 33 supporting the embedded or molded bristles 34.

The lateral surfaces 35, 35 of the bristle-supporting members 23-29 are streamlined and widely spaced from each other to permit the free passage of the water through the body and into contact with the downwardly projecting bristles 34.

Any suitable form of bristles may be employed; but the bristles are preferably molded plastic.

37 indicates integral molded plastic braces extending between the bristle-supporting members and increasing the rigidity of the frame.

The

end frame members

30, 31 are preferably curved convexly on the bottom and concavely on the top, causing the bristles 34 to diverge from each other at the bottom and further facilitating the cleaning of the bristles upon the passage of the water from the faucet.

A hot water faucet is also preferably employed, which melts the oils and other cosmetic products that may have been applied to the hair by means of the brush.

Referring to FIG. 8, this is a fragmentary top plan view of a modification in which the longitudinally extending

ribs

38, 39, 40 are formed with a plurality of cylindrical integral formations 41, each having a free bore 42 for receiving a plastic plug 43, which supports the bristles.

The plastic plugs have the bristles 44 embedded in a cylindrical plastic member 45; and the bristles may be extruded in the formation of the plugs 43, which carry a pointed head 46.

It should be understood that FIGS. 9-12 are enlarged; and the bristles may be made of any degree of fineness.

The assembly of the plugs and bristles with the brush of FIG. 8 may be accomplished by forcing the pointed head 46 through each of the bores 42, whereupon the heads 46 expand on the upper end of the bore 42, anchoring the bristle plugs in the brush.

Between the cylindrical enlargements 41 on the bristlesupporting members 3840 these bristle-supporting members may be made narrower and streamlined to pass the water more readily.

Referring to FIG. 15, this is a modification in which the brush is indicated in its entirety by the numeral 47; and the brush has the same streamlined bristle-supporting members 23-29, which are provided with lower flat surfaces 48, to which a strip 49 is cemented by a suitable cement, such as a plastic cement.

Each disc 49 supports a plurality of conical diverging bristles 50, 51; and this type of brush is particularly adapted to be used in massaging the scalp, as the bristles, while still resilient and bendable, are stiffer than bristles employed in the brushes of FIGS. 1-6.

The operation of the present brushes is as follows: When the brush is employed upon the hair or for massaging the scalp, certain hair dressing or cosmetics applied to the scalp or hair may adhere to the bristles and strands of hair become entangled or retained by the bristles.

The present brushes may be cleaned by running hot water from a water faucet on the top of the brush, the hot Water passing freely through the slots between the bristle-supporting members and engaging the bristles to drive off the hair and melt any products which may have adhered to the bristles.

It is unnecessary to use a comb to clean the bristles.

While I have illustrated a preferred embodiment of my invention, many modifications may be made without departing from the spirit of the invention, and I do not wish to be limited to the precise details of construction set forth, but desire to avail myself of all changes within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

A hair brush constructed and arranged to be self-cleaning when subjected to an upper stream of hot water under pressure from a faucet, comprising a molded plastic handle integrally secured to a molded rectangular frame, said frame having a pair of end frame members, said end frame members being joined by a pair of side frame members and by a plurality of longitudinally extending bristle supporting members, substantially parallel to said side frame members and similar in cross-sectional shape to said side frame members, the said side frame members and bristle supporting members being supported at their ends by the end frame members to form a brush having a generally concave back and the front thereof being generally convex, and each of said side frame members and said bristle supporting members being substantially elliptically shaped in cross-section, and formed with a flat bottom, and supporting in the bottoms thereof, a plurality of groups of diverging bristles, and the groups diverging from each other laterally, each of said bristle supporting members having a pointed upper edge, and being spaced from each other to pass the stream of water freely, and to clear the bristles of hair and foreign material.
