COMBINATION BOWL AND RIM BRUSH Filed May 15, 1940 FRANK I. KAF'INUE ATTU RN E7 Patentecl May 13, 1941 UNITED STATES FFEQE COIWBINATION BOWL AND RIM BRUSH Application May 15, 1940, Serial No. 335,212

3 Claims.

This invention relates to brushes suitable for cleaning the interior surface of bowls and the under surface of the usual overhanging rims or recessed grooves with which bowls are provided.

The object of the invention is to provide, bound to a suitable handle, a rim brush of bristles the flare of which is determined, restored and maintained by a resilient shoulder fixedly mounted upon the handle.

Further objects are to provide, combined in one I article having a common handle, the said rim brush and a bowl brush adapted to be manually plunged into a bowl for cleaning its interior surface in the ordinary manner, but with the rim brush capable upon the manual return movement to contact with the under surface of the overhanging bowl rim or groove; and to provide, bound to a suitable handle, a rim brush for use separately or in combination with a bowl brush of which alternate sections of the flared bristles of the rim brush are trimmed adjacent their binding to the handle to thereby retain only alternate tufts of bristles to best contact in turn with the under surface of the overhanging rim or grooves without distorting any of the bristles of which the rim brush is comprised, the efficiency of a rim brush not only depending upon the flare which it possesses but the maintenance of that flare in its normal condition.

In the accompanying drawing the Figure 1 is an upright View of the improved brush; the Figure 2 is an upright view of. the handle with an annular resilient shoulder fixedly mounted thereon; the Figure 3 is an upright view ofa handle slightly modified; and the Figure 4 is a cross-section on the line 4-4 of the Figure 1.

With'more particular reference to the drawin in represents the brush handle with the annular resilient shoulder II fixedly mounted thereon,. as at A. Also supported by the handle I!) adjacent the shoulder II is the combined bowl and rim brush, [2 and [2A, respectively, formed by layers of bristles bound to the handle in a manner already known to the art. No claim of invention is here made with reference as to how layers of bristles are formed and bound to the handle H] to provide the forwardly extending bowl portion of the brush, and likewise no invention is claimed with regard to an outer layer of bristles contributing both to the formation of the bowl brush and the rim brush by having forwardly and rearwardly extending bristles; for it is apparently old in the art to employ multiple layers of overlapping bristles bound midway along their length around an extremity of a handle and then folded, each layer upon itself, and then rebound to the handle to altogether provide forwardly extending bristles of the bowl portion of the brush, an outer layer of bristles being bound midway of their length, not folded, but with the bristles extending forwardly, completing the bowl brush, and rearwardly, forming an annular rim portion of the brush.

While the structure, as illustrated in the drawing, utilizes as its basis that which the art shows to be manifestly old yet the invention herein disclosed resides particularly in certain novel features herein introduced as an improvement in the art. In the improved structure the outer layer of bristles lEB is bound, as at I2H, to the handle id as were the previous layers shown to be in the earlier art, not folded however but with its bristles extending opposite ways from the binding lZH to complete in one direction the bowl brush l2 and in the other direction to provide the rim brush IZA which, in its process of construction is necessarily annular in form around the handle l0. But alternate sections of the annular formation of the rim brush l 2A are then trimmed, as at 82D, substantially close to the binding I2I-I to leave remaining the tufts of bristles IZE and lEF, each with their terminals [20 and the open spaces IZG existing therebetween.

This invention further resides in providing the resilient shoulder l I of any form or flexible material, but preferably of annular rubber ring struc ture, secured to the handle it, as at HA, placed snugly up against the closely trimmed terminals |2D and between the tufts of bristles HE and IZF, the resilient shoulder I l spreading the tufts [2E and IZF divergently, the outside diameter of the shoulder ll determining the degree spreading apart. Not only is this resilient shoulder II adapted for use with the alternately trimmed sections of the annular rim brush, but it is as well adapted for use in connection with the annular rim brush itself to establish and maintain a flexible flare.

A still further improvement from the viewpoint of economy is the simple construction of the handle II] which, as illustrated by the Figure 2, is of uniform dimension throughout its entire length.

This invention is subject, of course, to certain changes of construction of its parts without departing from the spirit or purpose thereof, and while the handle I0 is illustrated and described as having a uniform diameter throughout its entire length, the right is here reserved to employ, in connection with any of the other novel features herein disclosed, a brush handle provided with the manifestly old formations having an incline from which any layer or layers bound thereto may be made to take its slant, as illustrated by the Figure 3 where the tip IDA assumes a conical extremity.

By the foregoing description the advantages of the improved combination bowl and rim brush will be obvious; for in use when the rim portion of the brush is employed in cleaning a recessed or grooved under surface of a bowl rim, eithertuft IZE or IZF may be so directed as to contact directly therewith, the tufts [2E and IZF each being in readiness with a turn of the handle ill for a distinct alternate use as if each were a distinct brush. Before this improvement the rim brush was annular or skirt formation of such limited circumference in contrast with the larger circumference of the bowl rim that, in use where the under surface of the bowl rim is recessed or grooved, a portion of the skirt formation was of necessity cramped and distorted to the detriment of the life of the brush.

As a further advantage of the improved rimportion of the brush it will be recognized that the resilient shoulder ll not only maintains the relatively divergent positions of the tufts HE and IZF in normal condition but also protects against permanent bending and breaking of the bristles of the tufts I2E and IZF when in use they are jammed toward parallel alignment with the handle H); for under such circumstances the resilient shoulder yields at the place of pressure thus relieving the strain at the fulcrum point of the bristles, the normal condition of the tufts [2E and IZF being restored as the resilient shoulder H is allowed to expand.

I claim: 1. A combination bowl and rim brush comprising a handle; multiple layers of overlapping V the brush.

under said tufts and close to the binding of said clusters.

3. A brush supported by a handle, the brush including a layer of multiple clusters of bristles 'secured by a suitable binding around one extremity of the handle to provide relatively spaced tufts each convergently extending away from said handle extremity; and a shoulder member secured to the handle under the tufts and close to the binding of said clusters.
