Patented July 25, 1939 UNITED STAT-ES PATENT. OFFICE I BRUSH Wesley A. Sleeper, Los Angeles, Calif. Application May 14, 1938, Serial No. 207,948

, 4 Claims This invention relates to brushes.

The general object of the invention is to provide a. brush which may be mounted on a finger tip and which may be used for various purposes, as for example, a tooth brush. a

A more specific object of the invention is to provide a brush which is adapted to be placed upon a finger and which includes novel means for retaining the bristles in place.

Another object of the invention is to provide a brush which is adapted to be placed upon a finger and wherein novel means is provided for preventing accidental slipping of the brushfrom the finger.

Other objects and the advantages of this invention will be apparent from the following description taken in connection with the accompanying drawing, wherein:

Fig. l is a side elevation of a brush embodying the featuresof my invention;

Fig. 2 is a section taken on line 2-2 of Fig. 1;

Fig. 3 is a section taken on line 3--3 of Fig. 2;

Fig. 4 is a fragmentary section with parts broltslen a'way showing the arrangement of the bris- Fig. 5 is a side elevation of a modification;

Fig, 6 is a section taken on line 6-6 of Fig. 5;

Fig. 7 is a fragmentary section showing a modified manner of securing the bristles in place; and

Fig. 8 is a fragmentary section taken on line -8B Fig. 3.

Referring to the drawing by reference characters I have shown my invention as embodied in a brush which is indicated generally at. Ill. The brush is preferably elongated and hollow and is adapted to be placed for use upon a finger II asshown in Fig. 1.

The brush ll) includes a hollow outer body l2 which may be made of a metal, composition or rubber and which is preferably flexible although possessing sufficient rigidity to hold,its shape. The member I2 is provided with a plurality of pairs of apertures I3 which as shown in the drawing are arranged in parallel spaced rows; Each pair of apertures I3 is connected by a groove M. Thegrooves l4 are inwardly directed and receive the intermediate portions I5 of tufts of bristles which include and portions l6 which perform the brushing function. I

By disposing 'the intermediate portions l5 of the bristles in the grooves I! I am enabled to make the interior of the body I2 smooth and unbroken so that a liner I! which has an outer smooth and unbroken surface-directlyengages the interior of the body 12.

The liner I! may bemade of the same material as the body l2 and as shown is provided with apertures l8 near the open end which receive bosses IS on the outer surface of a'cushion member 20.

.The cushion member has a flange 2| thereon 5 shown in Fig. land is manipulated in the desired manner to provide the brushing action.

In Figs. Sand 6 I show a modification of my invention wherein the brush 25 is constructed similar to the brush l0 but whichis provided with a row of bristles 25 opposite a set of bristles v21. The outer edge of the bristles 26 are disposed in a concave line 28 while the bristles 21 have their ends convexly arranged as at 29. A brush of this character may be used by artisans, as for example, by watchmakers for brushing watch parts, etc.

In Fig. '7 I show a further modification of my invention wherein the outer body 30 and-liner 3| are similar in all respects to the outer body l2, and liner I? previously described, except that the 30 grooves l5 are omitted and single apertures 32 are provided through which bristles 33 extend. The bristles are knotted as at 34 at their inner end and the knot includes a wire member 35 inserted therein to add strength to the knot. 5

From the foregoing description it will be apparent that I haveinvented a novel brush hich can be economically manufactured and whi h is highly eflicie'nt for the intended service.

Having thus described my invention I claim:

1. In a brush finger tip device, a hollow outer rubber bodymember having apertures exten in I therethrough, said apertures being dispose in V aligned pairs said body having a groove between each pair of apertures, looped tufts of bristles 45 extending through each pair of apertures so that the free ends of the bristles are disposed without said body, the intermediate looped portion of said I /.bristles being disposed in said grooves and fiush with the inner surface of thebody, and a single, liner means within saidouter body member and engaging the intermediate portions of said bristles. 1

2. Ina brush, a hollow flexible rubber outer body member having apertures extending therethrough, said apertures being disposed in aligned pairs, tufts oi bristles extending through each of apertures, the intermediate portions of said bristles being disposed within said body, the

free ends of the bristles disposed without said body, an inner body member coextensive with said outer body, and disposed within said outer body member and engaging the intermediate portions'of said bristles and cushion means engaging the inner edge portion of the inner body member and the outer edge portion of the outer body member to hold the members assembled.

3. In a brush, a body made of flexible material and shaped to fit upon the end of a finger, said body having pairs of spaced apertures therein, a tuft of bristles passing through each pair of apertures and having its ends exposed on the outside of the brush, a'liner in said body, said liner .having a cushion member at the open end thereof means to hold said cushion member to said liner, said cushion member having a flange thereon spaced from the outer periphery of the liner to provide a groove, the perimetric edge of said body of the brush being fitted in said groove.

4. In a brush, a body made of flexible material and shaped to fit upon the end of a finger, said body having pairs of spaced apertures therein, a groove in said body connecting-said apertures, said grooves being disposed on the" inside of said body, a tuft of bristles passing through each pair of apertures and havi'ng its ends exposed on the Outside of the brush, a liner in said body, the

- interior of said body being smooth and unbroken and said liner being smooth and unbroken and directly engaging the body, said liner having a cushion member at the open end thereof, said liner having apertures therein, said cushion member including anchoring portions extending through said apertures whereby the cushion member is anchored, said cushion member having a flange thereonspaced from the outer periphery of the liner to provide a groove, said body 20 of the brush being fitted in said groove.
