LLTAMI OCESE, 0F SAN ANTGNTO, TEXAS,

TOTHBRUSH.

Application Bled May it, 1923. Serial No. 638,905.

To all whom t may concern.'

Be it known that l WILLIAM U'OHSE, a citizen of the United gtates, residing at the city of San Antonio, county of Bexar, and State of Texas, have invented a certain new and useful im rovement in Toothbrushes, of which the ollowing is a specification, reference being had to the accompanying drawing, forming a part thereof.

This inventionrelates to a certain new and useful improvement in tooth-brushes and has for its chief object the revision of a brush, whose functional sur ace comprises both an area especially designed for the cleansing of the relatively broad and flat anterior and posterior faces of the crown portions of the teeth, and also an areaof relatively thin or tapering section for extension interstitially of the-teeth for cleansing the opposed faces of the teeth.

W ith the above and other objectsjn view, rny present invention resides inthe novel features of form, construction, arran ement, and combination of parts hereinaiter described and afterwards pointed out in the claims.

Tn the accompanying drawing,

Figure l shows in side elevation a toothbrush constructed in accordance with my invention;

Figure 2 is a transverse sectional eleva-l tion of the brush taken approximately on the line 2-2, Figure l; and

Figure 3 is an elevation similar to Figure 2 of a inodied or alternate form of brush embodying my invention.

Referring now by numeralstothe said drawing, 1 designates the brush back or handle, supported by which is a relatively plane tooth-engaging area 2 and a tooth-engaging area comprising an element 3 of a relatively small section for extension between the teeth.

By preference, and as shown, the surface or area 2 is composed of the ends of bristles, or their equivalent, arran ed in tufts, such as secured in the brus handle, and by further reference the area or element 3 is compose of bristles, arranged in tufts 5,

tenuated or taperingvbristles 3, lengthwise of the brush and relatively spaced along the llongitudinal inedial line of the handle, and

to dispose the tufts t in parallel rows on o posite sides of the row of tufts 5, so that t' e relatively normally plane surfaces 2 formed by the flat ends of the tufts 4 contiguously parallel the attenuated or tapering bristles 3 of the tufts 5, the brush as a whole thereby resenting a substantially continuous surace composed of bristle ends which in the same operation, or synchronously, cleanse both the anterior and posterior faces of the crowns of the teeth and the opposed or interstitial faces of the teeth.

The modified form of brush illustrated in Figure 3 is substantially the same as the form of brush illustrated in Figures l and 2, except that the attenuated or tapering element 3 ofthe brush is composed of two parallel rows of the tufts 5, as shown.

My new brush may be readily and inexpensively manufactured and has been found exceedingly eiicient in the preservation of the teeth and useful in the remedial treatmentv of pyorrhea. T am aware that minor changes in the. form, construction, arrangement, and combination of the several parts of my new brush may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my inventicn,'what T claim land desire to secure by Letters Pattent is:

l. A tooth-brush including a back ro vided upon one face with outer rows an' an intermediate row of bristle tufts, said rows of tufts extending in contiguous `approximately parallel reiation longitudinally of the back, the free ends of the bristle tufts of the outer rows being trimmed at to normally reside on the same plane and the tufts g of the intermediate row being trimmed to taper outwardly of the back beyond the flat face of the outer rows.

2. A tooth-brush including a back pro- 5 vided upon one face with outer and inner rows of bristle tufts', said rows of bristle tufts extending in contiguous a proximately parellel relation longitudinal y of the back, the

free ends of the bristle tufts of the outer rows being trimmed flatto normally reside on the `l0 same plane and the tufts of the inner rows being trimmed to taper outwardly of the back beyond the fiat face of the outer rows.

In testimony whereof, I have signed my neme to this specification.

WILLIAM OCHSE.
