Filed July 21, 1958, Ser. No. 749,722

2 Claims. (Cl. 15-172 This invention relates to cleaning apparatus and moreparticularly to a utility brush.

It is an object of the present invention to provide a utility brush that includes a bristle brush which can be so adjusted to substantially prolong the useful life of the brush and to assure an effective leading edge on the brush at all times.

Another object of the present invention is to provide a utility cleaning brush of the above type having a replaceable brush element that can be readily adjusted whenever desired to distribute the wear evenly around the entire bristle portion thereof.

Other objects of the invention are to provide a utihty cleaning brush bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:

Figure 1 is a perspective view of a utility brush made in accordance with the present invention;

Figure 2 is a side elevational view of a brush and mounting disc forming a part of the present invention;

Figure 3 is a blank of the mounting disc forming a part of the present invention, prior to assembly with the bristle brush;

Figure 4 is an end elevational view of the mounting disc shown in Figure 3; and

Figure 5 is an enlarged fragmentary transverse cross sectional view taken along line 55 of Figure 2.

Referring now more in detail to the drawing, a utility brush made in accordance with the present invention is shown to include a handle 12 having a hole 13 at one end for supporting the unit upon a hook, hanger, or the like. The opposite end of the handle 12 is provided with a transverse bore 15 through which a bolt 16 extends for rotatably supporting a disc 17 thereon. A wing nut 19 threadedly carried by the bolt 16 which also extends through the central hole 18 in the disc plate, is operative to clamp the disc 17 in any desired rotated position.

As is more clearly shown in Figures 3 and 4 of the drawing, the disc =17 is provided with a plurality of circumferentially spaced apart radially outwardly extending tabs 27 that are struck around spaced apart portions of a twisted length of wire 25 which supports a large number of bristles 24. As a result, the bristle brush is secured to the periphery of the disc 17, in the manner shown in Figure 2, with bristles extending entirely around the circumference thereof.

The disc 17 is also provided with a plurality of angularly spaced apart and radially extending slots 22 which releasably receive positioning lugs 21 secured to the end of the handle 12 on diametrically opposite sides of the bearing bolt 16. It will thus be recognized that by loosening the wing nut 19, the disc 17 and attached bristle brush may be rotated any desired amount, following which the lugs 21 are engaged within the nearest slots 22 of the disc and the wing nut again tightened. In this way, the disc and brush can be rotated at various periods throughout the useful life of the bristles so as 'to distribute the wear upon the bristles uniformly. Ordinarily, the outermost end of the bristle brush, furthest from the hook receiving opening 13, is subjected to the greatest wear since it is used as a leading edge in various types of cleaning operations. Because of the arrangement of this brush, it is thus possible to rotate the brush as the leading edge becomes worn, to effectively prolong the useful life of the unit. When the bristles have been completely worn, it then becomes a simple matter to replace the entire disc 17 and connected bristle brush without affecting the usefulness of the handle 12.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. A utility brush comprising, in combination, a rigid elongated handle, a disc, bearing means rotatably supporting said disc upon one end of said rigid handle, a brush, securement means integrally fastening said brush to the periphery of said disc, positioning means releasably securing said disc in rotatably adjusted position upon said one end of said rigid handle, said bearing means comprising a bolt extending perpendicularly through said one end of said handle, a wing nut threadedly carried by said bolt clamping said disc upon said bolt, said brush comprising an elongated length of twisted wire, and a plurality of individual bristles carried along said length of twisted wire in substantially uniformly spaced apart and spirally disposed relationship, said securement means comprising a plurality of circumferentially spaced apart radially outwardly extending tabs struck over said twisted wire and encircling the periphery of said disc.

2. The combination according to claim 1, wherein said positioning means comprises a plurality of angularly spaced apart and radially extending slots in said disc, and at least one lug integral with said one end of said handle receivable within a selected one of said slots.
