In swaging the flange 8 inwardly care will be taken to avoid the formation of shoulders or projections,
as shown by Fig. 2, or the upper side of the said flange and of the adjacent edge portion of the back 5 will be flush with the upper sides of the projections or fingers 11. By thus carefully associating the parts of the brush an aseptic device of this character is provided, there being no crevices or openings or shoulders for the collection of germs or dirt at any point.
The brush consisting of the inner bristles 10 and outer surrounding rubber brush members or teeth 17 has been particularly devised for use as a combined cleansing and massaging brush, and in the use of this brush material benefits will accrue by reason of the fact that the bristles are shielded and prevented from having contact with the gums, the latter being engaged wholly by theyielding rubber brush lmembers or teeth 17 with a massaging effect, and by this means tender or soft gums will be strengtlr ened and hardened and at the same time the bristles 10 will be held upon the surface of the teeth for cleansing pur oses. The brush may be used either in right or left position with the same advantages. n
It is proposed to make the brush in various sizes and of different shapes, both as to peripheral and surface contours, and in view of the comparative simplicity of the brush embodying the cleansing and massaging features the cost of manufacture is materially reduced, especially in view of the fact` that the brush elements are secured within the back by the simple swaging operation of the flange 8 inwardly over the lprojections or fingers 11 and both parts of the brush elementsthereb simultaneously and accurately disposed within the back.
What is claimed is:
1. In a brush, the combination of a back, a stock carrying bristle members, and rubber brush members having a supporting base structurally independent of and held in the back by the stock and surrounding the periphery of the bristle members, a part of the back being project-ed inwardly and engaging the edge ofthe stock to secure the bristle and rubberv members in place.
2. In a brush, the combination of a back, a stock disposedin the back and carrying bristle members, and a rubber annulus carrying brush members surrounding the bristle members and having portions of the edge of the stock extending over and bearv ing thereon. l
3. In a brush, the combination of a back having a seat therein, a stock carrying bristle members and provided with peripheral outstanding projections with spaces therebetween, and a rubber annulus surrounding the stock beneath the projections and having brush members projecting through the spaces and surrounding the bristle members, the stock and annulus completely filling the seat of the back and secured by a portion of the. latter engaging the rojections.
4. In a brush, the com ination of a back having4 a seat therein, a stock carrying bristle members, and a double row of rubber brush members surrounding the bristle members and having carrying means independent of the stock and over which portions of the stock extend within the seat.
5. In a brush, the combination of a back, a stock carrying bristle members, and a rubber annulus surrounding and located beneath the edge portion of the stock and in.
terposed between the latter and the sides and ends of the `seat and having brush members extending upwardly through portions of the stock and completely surrounding the bristle members.
i 6. In a brush, the combination of a back having a seat therein with a iange surrounding the margin of the same, a stock disposed inthe seat and carrying bristle members, and a rubber annulus surrounding a portion .of the edge of the stock and having brush members projecting upwardly through the latter and completely surrounding the bristle members, portions of the stock projecting over the annulus andv having the flange of the back bent inwardly thereagainst.
7. In a brush, the combination of a back having a seat therein with a flange sur-` rounding the margin thereof, a rigid stock having a plurality of projections surrounding the periphery thereof with spaces therebetween, the upper port-ions of the ends of the projections being downwardly beveled, and a rubber annulus surrounding the stock beneath thelproject-ions and having rubber brush members extending upwardly through the projections, the stock having bristle gmembers located within the rubber brush members, the stock and annulus being secured in the back'by bending the ange of the latterv inwardly against the beveled ends of the projections and forming a flush joint with the upper surfaces of the said projections.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
