BRUSH.

Specification of Letters Patent.

Patented March 23, 1909 Application flied September 14, 19 08. Serial No. 462,864.

To all whom it may concern:

Be it known that I, l'lENRY ALEXANDER, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new. and

useful Improvements in Brushes, of which I the following is a specification.

The invention relates to such improve-T ments and consists ofrthe novel construction 0 and combination of parts hereinafter de scribed and subse uently claimed.

Reference may e had to the accompanying drawings, and the reference characters marked thereon, which form a part of this ".5 specification.

Similar characters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a face view of the improved brush, with the ends of the bristles cut off, to better show the face and edge of the brush. Fig. 2 is a vertical crosssection of the same taken on the broLen line "2-2 in Fig. 1, and showing the full length of 'the bristles inserted in the bristlead. Fig. 3 is a plan view of the perforate s rest of material, with its peri heral edge unbent. Fig. 4 is a plan view of t e metallic ring detached. Fig. 5 is a cross-section of the same taken on'the broken line 5T5 in Fig. 4. Fig. 6 is a cross-sectional view, showing a modified form of metallic ring. Figs. 5 and 6 are made-upon an enlarged scale.

The object of the invention is to provide thatclass of brushes in which the bristles are secured by a composition, in a recessed frame or back, with an attractive face and finished peripheral edge; also to effectively retain the bent-over peripheral edge of the erfvrate sheet, applied to the face of the liristle-pad, in a fixed position.

The invention consists of a perforate sheet of thin material ap lied to the face of a bristlead, in a brus of the class described, wit 1 its peri heral edge bent over the projecting perip eral edge of the bristle-pad, and a retaining ring of metal, forced onto the peripheral edge of the perforate sheet and pad under pressure, whereby the ring will exert contractional pressure upon the 5 peripheral bent-over edge of the perforate sheet, to hold it in place upon or against the peripheral edge of the bristle-pad,-as will be ereinafter more full described and subsequently pointed out in the claims. Referring to the drawings, the bruslrback I or frame, 1, is provided in its face with a irecess which contains the bristle-pad coni sisting of the composition, 2, and bristles 3. Before the composition is applied to the ends of the bristles, the bristles are inserted through the apertures or perforations in the perforate sheet, 5, made of thin material, as, for example, a thin sheet of celluloid having the perforations, 6, adapted to receive tufts of bristles which are inserted in the usual well known manner, and the composition a plied thereto, to form the inserted brist e- )ad, in any well known manner. ect of the sheet of celluloid, or other material, is to form a finished and attractive face on the bristle-pad. The peripheral edge of the perforate sheet is bent down against the projecting peripheral edge of the com osition forming the pad by the dies, in whicgi the pad is formed in the usual well known manner. After the bristle-pad is formed or inserted within the brush-back, a metallic ring, 10, is forced down by pressure of a die, or in any known manner, upon the peripheral edge of, the brush-back to the osition shown in Fig. 2. The size of the ring is such, that when it is forced to such position there is a tendency to expand the ring by reason of its engagement with the eripheral bent-over edge of the erforate s ect, and, when the ring is seate so as to inclose the peripheral edge of the perforate sheet, it will I enga e such peri hera edge with a contractiona force equa to the force of expansion which was applied to the ring in forcing it to its pro or position. The metal ring may be formed by die pressure either from rings cut from plane sheets of metal, or from sections of tubular metal. The metal rings are preferably so formed as to resent on their inner side a shar edge or ange, 12, adapted to engage an impinge upon the bent-over peripheral edge of the perforate sheet of matcrial, whereby the ring is prevented from slipping from its prroper position while the brush is in use. he metal ring serves to conceal the extreme lower ed e of the bentover portion of the perforate. sheet, and gives the brush an ornamental finish.

When desired, the ring may be made from a wire having a groove formed on its inner side, as shown in Fig. 6, wherein the wire, 14, is provided with a groove, 15, on its inner side, and the sharp edge or flange, 16, adapted to engage the perforate sheet.

The ohof such edge rated from the peripheral edge of the inserted It is obvious that the sharp edge of the ring which engages the bent-over peripheral edge of the perforate sheet of material, under ressure, W l impinge thereon suliiciently to e slightly embedded therein and thereby retain the ring in the position shown in the drawings, wherein it engages and rests upon the eripheral edge of the brush-back, and, at tl fe same time, securely retains the bentover peripheral edge of the perforate sheet in its bent-over position, preventing any part ecoming misplaced or sepapad. The ring serves not only to conceal the joint between the perforate sheet and the brush-back, but also to permanently retain the bent-over edge of the sheet in a fixed ing a brush-back having a recess in it's a bnstlead secured in said recess,and pro- -ject1ng t erefrom, having on its face a erbent position.

. What I claim as new and desire to secure by Letters Patent is 1. A brush of the class described com risface;

forate sheet ofthin material, through w ich the bristles roject, with its peripheral edge bent over t e projecting peripheral edge of the pad; and a retaining ring inclosing the projecting peripheral edge of the pad, adapted to engage, under pressure, the bent-over edge of the perforate sheet.

2.' A brush of the class described comprising a bruslbback having a recess in its face; a b'ristlead secured in said recess, and projecting terefrom, having on its face a erforate sheet of thin material, through W ich the bristles roject, with its'peripheral edge bent over t e projecting peripheral edgeof the pa'cl'j'and a metallic ring inclosing the projecting peripheral edge of thepad, having along its inner side a sharp edge adapted to engage, under pressure, the bent-over edge of the perforate sheet.

In testimony whereof, I have hereunto set my hand this 9th day of Sept. 1908.'

HENRY ALEXANDER.
