Application June 26, 1953, Serial No. 364,286

1 Claim. (Cl. 15394) This invention relates to a Venetian blind cleaner and is an improvement over the structure shown in my prior Patent No. 2,608,710 issued September 2, 1952, for Venetian Blind Cleaner.

An object of this invention is to provide a venetian blind cleaner which can be attached to a vacuum cleaner and which will clean both sides of the slats of a Venetian blind.

Another object of this invention is to provide an improved brush construction for a suction head to be attached to a suction hose of a vacuum cleaner.

A further object of this invention is to provide an improved brush construction which will eflfectively clean curved or flat slats.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a longitudinal section of a Venetian blind cleaner constructed according to an embodiment of this invention.

Figure 2 is a sectional view taken on the line 2--2 of Figure 1.

Figure 3 is a plan view of the brush.

Figure 4 is a fragmentary transverse section of a modified form of this invention.

Referring to the drawing and first to Figures 1, 2 and 3, the numeral designates generally a cylindrical body or nipple which is adapted to telescope over one end of a suction pipe or hose associated with a vacuum cleaner. The nipple or body 10 has projecting forwardly therefrom, a pair of hollow arms 11 and 12. The arms 11 and 12 are of like construction. Each arm is formed of

opposite side walls

13 and 14 and an outer wall 15.

A longitudinal curving inner wall 16 extends from the forward end of the nipple or body 10 projecting divergently outwardly and a connecting wall 17 is connected between the two arcuate walls 16. The

side walls

13 and 14 of each arm has extending longitudinally thereof, a pair of inwardly projecting flanges 18 and 19 which form guides or holders disposed in confronting relation and between which a brush member, generally indicated at 20, is adapted to removably engage. The brush member 20 is formed of a pair of longitudinally disposed side bars 21 connected together by inner and outer end walls or bars 22 and 23, respectively. The back 24 of brush 25 is disposed between the side members 21 and is fixed at the opposite ends thereof to the end walls or bars 22 and 23. The back 24 has projecting therefrom bristles 26 and as shown in Figure 1 the bristles of one brush 25 are disposed on a concave as indicated at 27, whereas the bristles of the other brush 25 are disposed on a convex curvature as indicated at 28.

The forward end wall 29 of each arm 11 and 12 is provided with a rabbet 30 within which a rib 31 carried by the outer bar or wall 23 is adapted to snugly engage. A finger piece 32 is formed integral with and projects outwardly from the outer end wall 23.

Referring now to Figure 4, there is disclosed a modified Patented Sept. 3, 1957 form of this invention wherein each hollow arm 11 is formed with parallel

opposite side walls

13 and 14 and a U-shaped guide or holder 33 is disposed parallel with the

side walls

13 and 14 and spaced inwardly therefrom. The opposite parallel walls 34 of the holder 33 are provided at their outer edges with inward projecting flanges 35 so as to snugly hold the back 36 of an elongated brush member 37 within the holder 33. In other respects the structure shown in Figure 4 is similar to that shown in Figures 1 and 2.

In the use and operation of this device, the nipple or cylindrical member 10 is telescoped over the outer end of a suction tube or pipe and the brush structure 20 is disposed Within each arm 11 and 12. Preferably, the back 24 of brush 25 is provided with one or more elongated openings. 38 so that air may be drawn through the bristles of the brush and through the back 24 in addition to being drawn through the space between the back 24 and the sides 21 of the brush structure 20. The Venetian blind slat is extended between the bristles of the two

brushes

25 and 25 with the arms 11 and 12 and the brushes contained therein disposed at substantially right angles to the length of the slat. The brush structure is then moved along the length of the slat and the brushes will remove the dust or other particles from the opposite faces of the slat in one operation.

What is claimed is:

In a suction device for simultaneously cleaning boflr sides of a Venetian blind slat in situ, a hollow cylindrical body for connection with a suction hose of a vacuum cleaner, a pair of hollow arms-communicating with said cylindrical body and extending integrally therefrom in spaced apart relation terminating in free ends, a connecting wall extending from one of said hollow arms to the other and integrally joined at its ends to said arms at a point spaced inwardly from the free ends thereof, said hollow arms each having spaced apart parallel side walls connected at their outer ends by an outer wall, said hollow arms having confronting substantially parallel inlet openings formed therein extending longitudinally from the free ends of said hollow arms to and terminating at said connecting wall, a pair of spaced apart parallel flanges formed on the opposing faces of each of said side walls adjacent said inlet opening, a pair of longitudinally extending confronting brushes including a back for each of said brushes secured thereto, and a transversely extending rigid end bar rigidly secured to each end of each of said backs with said bars each having their opposite ends engaging between adjacent flanges on said side walls for detachably mounting said backs in each of said inlet openings with said brushes dividing each of said inlet openings into a pair of inlet openings, said, hollow a-rms providing means whereby dirt loosened by said brushes will be entrained with air drawn into said divided inlet openings on each side of each brush and simultaneously dirt clinging to said brushes is sucked therefrom thus aiding in keeping said brushes clean, said connecting wall serving additionally as a limit stop for engagement against the side edge of the slats being cleaned.
