2 Claims.

This invention relates to new and useful improvements in brushes, more particularly to a brush structure adapted for use with vacuum cleaningl devices, and it is among the objects thereof to provide a brush having an adapter of rubber for mounting on the end of a manipulating sleeve connected by a hose to a vacuum clean er, the adapter having a recess for receiving a rubber set bristle brush, whereby the engagement of the` rubber portion of the brush with the rubber part of the adapter provides a removable yet firm connection between the parts.

It is another object of the invention to provide a utilityA brush for vacuum cleaners in which the brush element is replaceable without the removal of any fastening means by simply drawing it out of the rubber support.

Theseand other objects of the invention will become more apparent from a consideration of the accompanying drawing, constituting a part hereof, in which like reference characters designate like parts, and in which Fig. liis a vertical cross sectional view, partiallyin"elevation, of a brush and adapter ernbodying Athe principles of this invention; and

Figg2 a cross sectional view thereof taken along the line 2-2, Fig. 1.

In the drawing the numeral I designates a goose neck shaped sleeve of an adapter having a flanged end 2 for sliding over a relatively thin metalftube, the other end of which is connected by a flexible hose to a vacuum cleaner, not shown. The goose neck l terminates in a flanged end 3 having an annular groove 4, and a skirt portion 5 extends from the inner wall of the adapter a substantial distance below the flange 3.

Disposed within the annular groove 4 is a rubber set brush comprising an annular ring shaped elementi in which the brush bristles 1 are insertedin a plurality of holes 8, shown in Fig. 2,

` the bristles being vulcanized in the rubber or fastened therein in any suitable manner. Both the adapter and the bristle setting are made of soft rubber, the outer wall 9 of the rubber ring 6 having a rubberized fabric surface (not shown) to increase the friction of the brush ring with the The rubber ring 6 of the brush is assembled by sliding over the skirted` portion 5 and is forced into the annular groove 4 of the adapter as shown in Fig. 1 of the drawing. When so mounted the skirt portion. 5 constitutes a support for the relatively long bristles of the brush yet is flexible to permit free movement of the brush and prevent injury to furniture and other objects with which it may come in contact.

The frictional engagement of the rubber surfaces of the hair brush and adapter prevents dislodgment or dropping off of the brush from the 1 adapter yet permits removal of the brush from 'Qtlie adapter when desired.

No attaching means or clamping elements are `-@employed for fastening the brush to the adapter -by virtue of the frictional engagement and adhesive contact of the rubber parts, which en# -xhances the utility of the brush in general house- Lhold cleaning, since there are no metal parts which can come in contact with the parts to be cleaned.

Although one embodiment of the invention has `been herein illustrated and described, it will be @evident to those skilled in the art that various f-modiiications may be made in the details of construction without Adeparting from the principles herein set forth.

We claim:

,i 51. In a utility brush, an adapter having a. -,fii anged end of soft rubber with an annular groove etending therearound, said groove having spaced iside walls parallel throughout, a brush back com- `-prising an annulus having brush bristles fastened .tlrerein, said annulus being of soft rubber and forming a friction t with the walls of said an- .,nular groove to firmly secure the brush back .therein without other fastening means. yet permitting easy removal and replacement thereof.

2. A cleaner nozzle for an air-suction hose comprising a body portion having an inlet mouth at one end, a groove extending around the edge of 4Said mouth, said groove having spaced side walls g, parallel throughout, a brush back removably disposed in said groove, said back being in the form l-an endless loop dening an opening of a shape f'corresponding to that of said mouth and being rijd-apted to fit snugly between the walls of said gifeove and material-engaging means extending from the outer side of the loop, said inlet mouth and said back having their contacting surfaces of `soft rubber whereby the mouth holds the back .against accidental dislodgment during normal cleaning operations but permits removal and re- .;placement of the back when said means have become worn.
