United States Patent Otfice 2,746,074 Patented May 22, 1956 DUSTER Lawrence A. Carlson, Sr., Minneapolis, Minn.

Application May 28, 1953, Serial No. 358,070

3 Claims. (Cl. 15-210) My invention relates to clusters and more particularly to relatively thin elongated dusters of the type utilizable in cleaning of Venetian blinds, between radiator sections, and the like.

The primary object of my invention is the provision of a novel cluster of the type above described in which the dusting surfaces may be quickly changed without dislodging of dust and dirt therefrom.

A still further object of my invention is the provision of a device of the class described which includes a duster body having a removable and reversible dusting skirt, which skirt is inexpensive to produce, durable in use, and easy to clean by ordinary washing.

A still further object of my invention is the provision of a device of the class described which is provided with a pair of elongated generally rectangular relatively thin fiat matched body members hinged together along adjacent longitudinal edges for swinging movements from an edge to edge relationship to a face to face relationship in opposite directions and having longitudinally extended handle portions at one end thereof, and in combination with an elongated tubular fabric dusting skirt telescopically receivable over said body members when same are swung to an edge to edge relationship, said tubular dusting skirt being foldable with said body members.

Still more specifically, an object of my invention is the provision of a device of the class immediately above described in which the body members are hinged together along their longitudinal edges by means of a rough strip of fabric, said rough surface of said fabric frictionally engaging said dusting skirt and thus tending to retain same in operative position during folding movements and during use.

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

Referring to the drawings, wherein like characters are indicated by like parts throughout the several views:

Fig. 1 is a perspective view of my novel device;

Fig. 2 is a view corresponding to Fig. l but showing the dusting skirt attached thereto;

Fig. 3 is a slightly enlarged perspective view of the dusting skirt of my novel invention;

Fig. 4 is a greatly enlarged view in transverse section taken on the line 4-4 of Fig. 2;

Fig. 5 is a view corresponding to Fig. 4 but showing the parts thereof in a folded position; and

Fig. 6 is a perspective view corresponding to Fig. 2 but showing the parts in a folded operative condition.

Referring with greater particularity to the drawings, the numerals 1 and 2 indicate a pair of relatively flat generally rectangular thin body members having longitudinally extended handle portions 3 at their rear ends. As shown, the opposed longitudinal edges 4 and 5, respectively, of the body members 1 and 2 are hinged together in slightly spaced relationship by means of a fabric strip 6 having a relatively rough surface. Hinge strip 6 may be secured to the body members 1 and 2 by any suitable means such as adhesive, preferably and as shown the same overlying the faces 7 and 8, respectively, to a considerable extent so as to impart to the faces 7 and 8, at least on one side of each thereof, a relatively rough surface. Adapted to be telescopically received over the body members l and 2 is a tubular dusting skirt 9. Skirt 9 has a width not greatly in excess of the combined widths of the body members 1 and 2 when in edge to edge relationship and has a depth corresponding roughly to that of the bodies 1 and 2.

In use, a clean dusting skirt 9 is placed telescopically over the hinged body members 1 and 2 of Fig. 1 in the manner of Fig. 2. Thereafter, the body members 1 and 2 are folded in either direction upon the hinge strip 6 causing the dusting skirt 9 to be intucked in the manner of Figs. 5 and 6. When the exposed opposite surfaces of the duster skirt 9 become dirty and dusty, it is but necessary to swing the body members 1 and 2 on the hinge 6 whereby to cause the opposite faces of the body members 1 and 2 to come into contact with each other and expose the clean surface of the dusting skirt 9, formerly intucked between the body members 1 and 2, while simultaneously intucking the former dirty or contaminated surface. When these surfaces become too dirty for efiicient dusting, the dusting skirt 9 may be removed from the body members 1 and 2 and turned inside out. Thus the effective usefulness of a particular clean dusting skirt is doubled. As above indicated, this structure is particularly adaptable for use in dusting Venetian blinds and getting into other narrow or restricted areas or openings such as between the several sections of the conventional cast iron radiator.

My invention has been thoroughly tested and found to be completely satisfactory for the accomplishment of the above objects, and while I have disclosed a preferred embodiment thereof, it should be obvious that same is capable of modification without departure from the scope of the appended claims.

What I claim is:

1. A duster comprising a pair of elongated generally rectangular relatively thin flat matching body members hinged together along adjacent longitudinal edges for swinging movements from an edge to edge parallel relationship to a face to face relationship in opposite directions and having reduced axially extended handle portions at one end thereof, and an elongated tubular fabric dusting skirt telescopically receivable over said body members when swung to said edge to edge relationship and foldable therewith.

2. The structure defined in claim 1 in which said tubular skirt has a depth corresponding roughly to that of said rectangular body members, and said body members presenting a relatively rough surface portion frictionally engageable with said dusting skirt.

3. The structure defined in claim 1 in which said hinge is in the nature of an elongated strip of fabric material which overlaps the adjacent edges of said body members and is secured thereto, said fabric hinge defining a relatively rough surface.
