April 23, 1940. A M ToN 2,198,339

BRUSH Filed May 28, 1958 In ventor Attorneys Patented Apr. 23, 1940 UNITED STATES PATENT OFFICE 1 Claim.

10 blinds or within and about the various tubes of a radiator to loosen all dirt and foreign matter so that it may be taken up by thesuction' from the vacuum cleaner first passing through the body of the brush which due to its construc- 15 tion may be brought in close contact with the dirt to assure of its removal.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts I to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which:

ll Figure 1 is a plan view illustrating a brush constructed in accordance with my invention.

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

Referring in detail to the drawing, the numeral 80 5 indicates the body of a brush, one end portion of which is reduced to form a tube like neck 8 which may be easily inserted in a suction pipe of a vacuum cleaner (not shown). The body 5 is of elongated formation and of substantially elliptical shape in cross section and has secured thereto a plurality of tufts of bristles I. The tufts of bristles I extend the full length of the body and are arranged on opposite sides thereof and also along the edges of the body. The body is provided in opposite sides thereof with elongated shaped openings 8 and also has its free end open. The body adjacent the free end is arcuately curved, as clearly shown in Figure 1, and has an opening 9 formed in the inner curved wall, as shown in Figure 1. The curved end portion of the body permits of the brush being easily worked into inaccessible places and to engage the rear faces of parts of a device such as the tubes of a radiator while the body is being moved upwardly and downwardly between the tubes. The curved portion of the body also permits the body to be conveniently worked about the usual waterbacks of the radiator. As the brush is moved upwardly and downwardly with the bristles riding against the various parts of the radiator the dirt accumulated on the radiator will be loosened and drawn in through the various openings of the body and then passed to the vacuum cleaner by the suction developed by said vacuum cleaner. The brush can also be conveniently employed for removing dust, dirt and the like from slats of Venetian blinds, the shape of said brush facilitating the easy insertion and moving of the brush between the slats so that dirt will be easily removed and taken up by the vacuum cleaner connected to the brush.

While a detailed description has been given of the use of this brush for removing dirt and foreign matter from radiators, Venetian blinds, it is to be understood that this brush can be conveniently employed for cleaning any other device wherein the parts are spaced and inaccessible.

It is believed that the foregoing description, when taken in connection with the drawing will fully set forth the construction and advantages of this invention to those skilled in the art to which such device relates, so that further detailed description will not be required.

Having described the invention, I claim:

A brush comprising an elongated hollow body having one end reduced to form a neck for insertion into a suction hose and provided at the opposite end with an arcuate curvature with said last-named end open and cut on a bias, said body being of substantially elliptical shape in cross section to provide opposed edges and opposed convex walls and provided with openings, said body tapering gradually from the neck to the latter-named end, and tufts of bristles secured on the edges and opposed convex walls of the body.
