ATTO/PA/fy 2,858,559 DUSTING MOP FOR USE OVER FLOUR BRUSH Lawrence A.' Carlson, Sr., Minneapolis, Minn.

Application March 16, 1953, Serial No. 342,603 3 Claims. (Cl. 15247) My invention relates generally to improvements in cleaning and dusting tools and more particularly to improvements in that type of cleaning and dusting tools comprising a oor brush, or equivalent basic tool, and an associated soft flexible dusting cloth.

In the sweeping of uncarpeted floors of marble, terrazzo, linoleum, wood and the like, the raising of dust in places such as large offices, laboratories and the like, presents a problem. In such places, the conventional dust mop is not adequate to remove the dust thoroughly, even with frequent shaking out of the mop, and a bristle brush or broom does not satisfactorily remove all of the fine dust. Even when used with extreme care, a bristle brush tends to raise dust into the air from whence it settles on equipment in the room, thereby adding to the labors of the janitor or cleaning person. For the purpose of eliciently dusting large floor areas and the like, it has been found that a chemically treated dust cloth detachably Asecured to the head of a floor brush operates to remove dust without raising dust particles in the air, provided that the dust cloth is maintained in an operative position between the bristles of the brush and the surface to be cleaned and providing that there be additional dusting cloth material to lay in loose wiping contact with the surface to be cleaned both in front of and in back of the brush head. An important object of my invention is therefore the provision of an improved tool comprising a soft flexible dust collecting element which when mounted o-n the head of a oor brush or equivalent basic tool will be interposed automatically between the bristles or other yieldable facing thereof of the brush and the surface to be wiped thereby and which will provide an excess of soft, flexible wiping material both ahead of and behind the tool head and to allow shifting of the soft flexible material to dispose different portions thereof between the tool head and the floor or other surface being wiped.

Another object of my invention is the provision of a dust cloth which may be quickly and easily mounted on and removed from a brush for cleaning or the like, and which when mounted on the brush head is not subject to United States Patent C) accidental removal or displacement from operative position.

-Another object of my invention is the provision of a dust cloth o-f the type set forth which is easily reversible to permit use of both sides thereof for dust collecting purposes.

Still another object of my invention is the provision of an improved tool of the character set forth which is simple and inexpensive to manufacture and install, which is efficient in operation, and which is extremely durable in use.

The above and still further objects and advantages of my invention will become apparent from the following detailed specification, appended claims and attached drawings.

Referring to the drawings, which illustrate the inven- Nice tion, and in which like reference characters indicate like parts throughout the several views:

Fig. 1 is a view in perspective, with some parts broken away and some parts shown in section, showing one form of floor brush having my novel dusting cloth mounted thereon;

Fig. 2 is a fragmentary view in side elevation illustrating a preferred method of applying my novel dusting cloth t-o the floor brush of Fig. l;

Fig. 3 is an enlarged transverse sectional view taken substantially on the line 3-3 of Fig. l; and

Fig. 4 is a view corresponding to Fig. 3 but showing my novel dust cloth applied to a different form of floor brush.

In the preferred form of the invention illustrated, my novel cleaning and dusting tool comprises a permanently formed, circumferentially endless, reversible tube 1 of constant diameter made from suitable cloth fabric material and open at its opposite ends 2 and 3 for insertion of an elongated basic tool head which preferably takes the form of a bristle-equipped brush head 4. The brush head comprises an elongated rigid backing 4a and brush bristles 8. The brush bristles 8 define a yieldable facing providing a relatively deectable bottom working surface for the tool head 4 that extends an appreciable distance on opposite sides of the handle 6. At its longitudinal central portion, the tube 1 is provided with an opening 5 intermediate its ends for freely receiving a brush handle 6 which preferably and as shown is connected to the longitudinal center of the brush head 4 by a conventional universal joint 7. The joint 7 permits the brush handle 6 to be swingably displaced from a normal operative position at substantially right angles to the head 4 to an extreme assembly position generally parallel to the head 4, as shown in Fig. 2. Also preferably and as shown, the tube 1, which is of substantially constant diameter from end to end, is of greater length than the brush head 4 and has a diameter which is substantially larger than the maximum width of the brush head 4 so that, when the tube 1 is mounted on the brush head, it will encompass the entire brush head and at all times be situated between the bristles 8 of the brush and the underlying wall or oor surface to be dusted. Said surface is indicated by the letter X in Fig. 3. v

When my novel dusting cloth is to be applied to the brush of Figs. 1 to 3 inclusive, the brush handle 6 is moved from its normal operative position of Figs. l and 3 into its assembly position wherein it is generally parallel to the head 4; such handle displacement being made necessary because of the fact that the maximum pose sible diameter of the tubular cloth is greatly less than the length of the handle 6. The free end of the handle 6 is then inserted through one of the open ends 2 or 3 of the tube 1 and outwardly through the central opening 5 therein. The cloth tube is then moved along the handle 6 towards its connection to the brush head 4 and the adjacent end of the brush head 4 is inserted into the tube. When the central aperture 5 reaches the joint 7, the tube 1 will be centered on the brush head with the opposite ends 2 and 3 thereof overlapping the opposite ends of the head 4. Then when the handle 6 is moved to its operative position of Fig. 1, there is little, if any, likelihood of accidental removal of the dusting cloth from the brush head.

When it is desired to remove the tubular dusting cloth l from the brush head 4, it is merely necessary to swing the handle 6 into its said assembly position in generally parallel relationship with the brush head 4 and slide the tube 1 toward the free end of the handle d in a manner directly reverse to that used in mounting the dust cloth on the brush head.
