UNITED STATES PATENT OFFICE.

FRANK R. WEBER, OF TROY, NEW YORK, ASSIGNOR TO MOHAWK BRUSH COMPANY, OF ALBANY, NEW YORK, A CORPORATION OF NEW YORK.

HAIRBRU SH.

Reference may be had to the accompanymg drawings, and the reference characters marked thereon. which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

The principal object of the invention is to provide a strong light-weight back and handle for a brush having a substantially semicylindrical bristle-face.

Other objects will appear in connection with the following description.

Fig. 1 of the drawings is a top plan view of a hair-brush embodying my invention. Fig. 2 is a side elevation of the same.

Fig. 3 is a cross-section of the same taken on the broken line 3-3 in Fig. 2. Fig. 4 is a plan view of a blank of celluloid adapted to be formed into a back and handle for a brush embodying my invention. Fig. 5 is a cross-section of the same taken on the broken line 5-5 in Fig. 4.

Referring to the drawings wherein the invention is shown in preferred form, 1 is the brush back which is semicircular in crosssection as shown in Fig. 3. and which has a handle, 2, formed by an integral longitudinal extension of the middle portion of the back.

The back and handle may be made in the form shown of wood, or metal. or of celluloid, vulcanite or other moldable material.

I prefer to make the back and handle of sheet celluloid, or similar sheet material which becomes plastic when heated.

In Fig. 4, I have shown a blank of sheet celluloid adapted to be molded into a brush back and handle adapted for carrying out my invention.

The portion of the blank adapted to form the back of the brush is formed with side wings, 1, adapted when heated to be upturned in a suitable mold or die to semicircular form in cross-section as shown in Fig. 3, and when cool to retain this semicircular form.

If made of metal, the back and handle may be castin a mold.

If made of wood, .the back and handle may be cut and machined to the desired form.

By forming the back channelor U-shaped by Letters Application filed August 27, 1925. Serial No. 52,830.

in cross-section I am able to produce a brush-back and handle of very light weight. but of greatstrength and rigidity. This U shaped cross section of the back also provides an arcuate finger receiving groove defined in the space between the angularlydisposed longitudinal edges of the back which will facilitate the manipulation of the brush.

The bristles. project radially from the outer cylindrical surface of the back.

The bristles are preferably arranged in parallel rows oi tufts. parallel with the axis oi said semi-cylindrical surface. The tufts of the various rows are arranged in staggered relationship as clearly shown in Figure 2.

The outermost-rows on opposite sides of the back project in diametrically opposite directions, and the intermediate rows project in outwardly diverging relationship so that the outer ends of the bristles in each row are spaced at distance from the corresponding ends of the bristles in adjacent rows.

The bristles are of substantially the same length and thus present a substantially semicylindrical bristle-face for engagement with the hair.

In use the brush is engaged with the hair with a rocking or rolling movement of the semicvlindrical bristle-face against the hair.

I do not wish to be limited to the constructions shown and above described. as for certain purposes of the invention, various changes may be made in the form and arrangement of various parts of the device, without departing from the spirit of the invention, or the scope of the appended claim.

What I claim as new and desire to secure Patent is-- A hair brush comprising an elongated body portion, one end thereof forming a handle and the other end thereof being relatively thin and having its longitudinal sides curled upwardly to provide a brush back substantially U- haped in cross section, and a plurality of bristles arranged inlongitudinally extending substantially parallel rows and projecting outwardly from the convex face of said substantially U-shaped back, said bristle tufts providing a brushing and combing surface which is substantially at least semi-circular and the outer ends of i the tufts of each row being spaced from the ends of the tufts of adjacent rows whereby to provide a series of combing and brushing rows which may be successively presented to the hair by rotating the handle and back illsthe brush is also moved bodily over the 10 In testimony whereof, I have hereunto set my hand this 30th day of July, 1925.

FRANK R. WEBER.
