CREVICE TOOL FOR SUCTION. CLEANERS Filed Oct. 11, 1951 A MEI r INVENTOR. l J04 m5 P 14 150 ATTORNEY Patented May 25, 1954 2,679,068 CBEVICE TOOL FOR SUCTION CLEANERS Julius P.

2 Claims.

flexible extension hose terminating in a rigid tube or wand adapted to recelve various types of cleaning tools. Among such tools is a crevice tool having a tubular portion of circular cross section adapted to telescope or interfit with the hose wand which merges with a portion or blade of rectangular cross section of a size which may be projected between the slats of Venetian blinds or the fins of home heating radiators or the like. In many instances it is desired to combine the suction effect with a brushing action for thorough cleaning, but a permanently affixed brush prevents efiective use of such a tool in cases where only limited space is available for inserting the tool.

I have developed a crevice tool having a brush which is quickly and easily detachable from and attachable to the tool. Further, the brush is so shaped that it tends to break up a straight line suction effect and cause a lateral suction which is highly desirable in cleaning Venetian blinds and the like.

According to the invention, the brush has a portion of U-shaped cross section adapted to be telescoped within the open end of the tool blade and a pointed or V-shaped exposed portion having upstanding bristles whereby when the tool is projected between the slats of a Venetian blind or the like the bristles will brush the slat and at least a part of the suction effect will be in a direction generally at right angles to the slats surface. When it is desired to use the tool without the brush, th brush is merely pulled out of telescoping relation with the tool proper.

It is a primary object of the invention to provide an improved crevice tool for attachment to the extension hose of a suction cleaner.

Another object of the invention is to provide a brush for a crevice tool of the above type which can be quickly and easily attached to and removed from the tool.

Another object of the invention is to provide a crevic tool of the above type having a detachable brush which serves a dual function of acting as a brush and directing at least a portion of the air flow in a direction generally at right angles to the tool blade.

Other objects of the invention and the invention itself will become increasingly apparent from a consideration of the following description and drawings, wherein:

Figure 1 is a fragmentary plan view of a crevice tool embodying the invention;

Figure 2 is an elevational view of the tool shown in Fig. 1;

Figure 3 is a plan view of the brush attachment illustrated in Figs. 1 and 2; and

Figure 4 is a transverse sectional view taken along the lin 4-4 of Fig. 3.

Referring now to the drawings, I have indicated generally at H] a conventional crevice tool comprising a tubular portion I I adapted to telescope over and have a tight fit with the wand of an extension hose coupled to a suction cleaner. Portion H merges into a portion [2 of rectangular cross section which preferably terminates in an end l3 cut angularly. The tool I0 is usually formed of metal or a suitable class of material.

The brush generally indicated at 14 comprises a frame I5, preferably formed of plastic material, having a thin walled portion I6 of U form cross section and a thickened lip or edge portion 11. It will be noted that lip 11 extends beneath the bottom wall of portion It a distance corresponding to the thickness of the bottom wall of rectangular portion 12 of tool l0 and extends laterally beyond each side wall of portion is. The bottom edge of lip I1 is cut angularly to correspond with end l3 of tool 10, as indicated at l8, whereby this edge together with

side edges

19 and 24 abut the end of tool portion l2 to limit relative telescoping action between the tool and brush and form an effective seal therebetween when brush portion [6 is projected within tool portion I2.

Lip I1 is of generally V shape in plan view, since I have found this shape most effective when projecting the brush into corners and the like. A plurality of holes are formed in the lip to receive brush bristles, as indicated at 22, the bristles being secured in any suitable manner as by bonding or stapling. It will be noted that the lip walls extend upwardly to be substantially flush with the top wall of tool portion l2 and form a recess, indicated at 23, adjacent the end of tool Ill. The height of lip I! which includes the thickness of the frame bottom wall forming the base of recess 23, substantially conforms to the depth of the tool blade, indicated as portion [2 as illustrated in Fig. 2. It will be apparent that when the tool is used either for suction cleaning or blowing that the lip walls together with the upstanding bristles will tend to direct the air stream at right angles to the tool which is highly desirable for efficient cleaning when the tool is projected between the slats of Venetian blinds or the like, since the air stream will be directed toward or I wish it to be understood that I do not desire to be limited to the exact details-of construction shown and described, for obvious modifications will occur to a person skilled in the art.

What I claim is:

1. The combination with a'creyi'se'tool adapted to be attached to a suction cleaner extension'rhose and of the type having a blade with anuopening generally rectangular incross section, ofa i brush adapted to be detachably secured to the tool,

wsaid' brush-comprising I a frame' formed of solid rigid material and haying' a thin wall poi tiomof U cress section adapted -to be'- telescope'davithin the blade, the base of the frame of the U section substantially I conforming to the wid-th er the blade opening and the upstanding-legs=ofsaid seotion substantially: conforming to the depth of the blade opening whe'reby 'the framerormsa relatively tight fit W ith -the blade, the base of the U section extending forwardly of the blade engaging portion, the extending portion having an upstanding thickened peripheral lip having a height substantially conforming to the depth of 5 the blade and adapted to abut the sides of the blade to form an upwardly open recess forwardly of="'the'=-blade, and brush bristl'es -=ex-tending upwardly from ithe lip whereby the" lip ivvall and bristles will tend to deflect air at right angles to ithe blade during use of the tool.

The combination described in claim 1 and -wherein"the'extending base portion of the frame -is-ofigenerally -V form with the apex of the V 'emotefromthe blade, and the lip forms a gener- 'ibilly Vfishapdawall for the recess.
