United States Patent O DUSTING DEVICE Wallace C. Godfrey, Milwaukee, Wis. Application August 9, 1957, Serial No. 677,250

Claims. c1. 15-210 This invention relates to a dusting device.

More particularly this invention relates to a dusting device which is particularly adapted for use in dusting church pews, benches, rows of theater seats, and the like.-

Ithas been found heretofore that in dusting church pews, benches, theater seats, and the like, with conventional dusting devices or dusting mops, considerable time and labor are involved in dusting the entire seat, back and front portions of church pews, benches, theater seats, and the like. 7

An object of the present invention is to provide a new and improved dusting device which is particularly adapted to dustexpeditiously both the back rest and seat portions. of church pews, benches, theater seats, and the like, in a single dusting movement or operation, with resulting economy in both time and labor.

, Another object of the invention is to provide a new and. improved dusting device which is particularly adapted to dust the back rest and seat portions of church pews, benches, theater seats, and the like, and their top and frontedges, respectively, in a single dusting movement or operation, with resulting'ineconomy in time and labor. t

A further object of the invention is to provide a new and improved dusting device which is particularly adapted for dusting church pews, benches, theater seats, and the like, and which is relatively simple and inexpensive in construction and efficient in use. p

Other objects will appear hereinafter.

In the drawing:

Fig. 1 is a fragmentary perspective view showingthe new dusting device as used in dusting a typical church P Fig. 2 is a view, partly in section, partly in elevation, and partly diagrammatic, showing the new dusting device, as shown in Fig. 1, and as used to dust a church n Fig. 3 is an enlarged fragmentary detail view showing certain of the details of construction of the flexible coiled mop cord fabric supporting member and of the handle construction therefor;

Fig. 4 is a fragmentary detail view showing the manner in which the flexible coiled wire supporting member for the mop cord fabric is attached to the tubular handle member;

Fig. 5 is a sectional plan view on line 5 in Fig. 4;

Fig. 6 is a sectional plan view on line 6-6 in Fig. 4;

Fig. 7 is a plan view of a locking ring embodied in the new dusting device;

Fig. 8 is an elevational view of the locking ring shown in Fig. 7; and

Fig. 9 is a sectional view on line 99 in Fig. 7.

A preferred embodiment of the new dusting device is shown in the drawing, where it is generally indicated at 10, and includes a flexible mop cord fabric dusting element 11, and a handle unit, generally indicated at 12. The handle unit 12 is preferably made of relatively light material, such, for example, as tubular aluminum stock and is generally L-shaped in form, and the (in use) horizontal arm of the tubular handle has a hand grip 13 mounted thereon, in any suitable manner, as by being adhesively secured thereto, as at 14.

The dusting element 11 is generally L-shaped in form and includes, as shown, a flexible wire support for the mop cord fabric embodied therein, and, in the form shown, the flexible wire supporting unit includes three flexible wire supporting elements, 15, 16 and 17 which; are formed, shaped, and interconnected, in the manner illustrated in Fig. 2, to provide a flexible wire support which is geerally L-shaped in form, as best shown in Fig. 2, and includes two generally right angularly inter secting arms. Each of the flexible wire supporting ele-

g ments

15, 16 and 17 is composed of a plurality of inter'-- twisted wire strands and has a mass of mop cord clothor fabric 18 intertwisted therewith so that the mop cord, fabric is composed of a mass of the mop cords 18 inter. twisted with the flexible wire supporting elements 15,

7 16 and 17, as shown in dotted lines in Figs. 3 and-'4.

Such corded or tufted dusting fabric material is well known commercially and is made by intertwisting the; fabric tufts or cords through the strands of the flexible.

wire supporting elements

15, 16 and 17. The dusting. element 11 includes an (in use) rearwardly outwardly and downwardly extending upper end portion 29 and a for? wardly and downwardly curved lower end portion 30. (Figs. 1 and 2). W V

In order to mount the flexible

wire supporting elements

15, 16 and 17 upon, and so as to connect them to, the

tubular handle unit 12, I may employ any suitable fastening means but in the form of the invention shown in the drawings I employ the fastening arrangement illus trated in Figs. 3, 4, 5, 6, 7, 8 and 9.

Thus, as shown in Figs. 3, 4, 5, 6, 7, 8 and 9 there is? I illustrated a suitable means for fastening the adjacent end portions of the flexible wire supporting elements 15 and 16 in and to the (in use) horizontally extending arm ofthe L-shaped tubular handle unit 12, and since the.

means shown for fastening the end portions of the flexible

wire supporting elements

16 and 17 in and to the (in use) vertically extending arm 19 of the tubular handle lllllLlZ? is the same .as themeans'emplo'yed for fasteningtheendi portions of the flexible wire supporting elements 15 and 16 to the (in use) horizontally extending arm of the tubular handle unit 12, only one such fastening or connecting means will be described. Thus, the fastening means shown consists of bending the

end portions

15a and 16a of the flexible wire supporting elements 15 and 16 into parallel and juxtaposed relation and then inserting them into an internally threaded coupling member 24 in which they are soldered or otherwise secured as by solder 25 poured thereinto and interlocked with the internal threads of the coupling member 24 and with the

end portions

15a and 16a of the flexible wire supporting element 15 and 16 respectively. The fastening means is completed by an annular internally threaded clamping member 22 which is threaded onto an externally threaded reduced portion 23 of the coupling member 24, and encircles an end portion 20 of the tubular handle section 19. A resilient split locking ring 21 is arranged about the end portion 20 of the tubular handle section 19 between the latter and the clamping member 22 and is seated in an annular groove 31 formed on the inner surface of the member 22 (Fig. 4).

In the use of the new dusting device the same may be readily manually grasped by the hand grip 13 and the upwardly extending portion of the dusting element 11 positioned in contact with the front surface of the back rest portion of a church pew, bench, theater seat, or the like and with the upper end portion 29 extending outwardly over and somewhat downwardly behind the top edge of the back rest portion 28 of the church pew, or the like (Figs. 1 and 2), at the same time, the horizontally extending arm of the new dusting device is positioned in contact with the upper surface of the seat portion 27 of a church pew 26, or the like, with the lower end portion extending forwardly and downwardly over the front edge of the seat portion 27 of the church pew 26 or the like.

In the use of the new dusting device, and when the same is positioned as shown in Figs. 1 and 2, it may be moved horizontally across a church pew 26, bench, theater seat, or the like, by merely grasping the hand grip 13 and sliding the dusting device horizontally across the pew or the like, while keeping the tufted or corded dusting element 18 in contact with the back rest and seat portions of the church pew, bench, theater seat, or the like. 1 During this operation the new dusting device effectively dusts both the front surface of the back rest portion and-the top edge thereof and the upper surface and front edge of the seat portion of a church pew, bench, theater seat, or the like in a single operation, and thus effects a substantial economy in time and labor, as compared to prior dusting mops and the like.

It will be noted in this connection, that the flexible generally L-shaped wire unit 15-1617 is somewhat yieldable or resilient and this enables the new dusting device to have a limited accommodation to the surface or contour of the church pew, bench, theater seat, or the like, since the wire supporting frame 15-16--17 will yield somewhat under manual pressure by the user, and the wire employed in the supporting unit 15-16-47 is of such a gauge and hardness that, while having sufiicient strength, it is somewhat flexible.

It will thus be seen from the foregoing description, considered in conjunction with the accompanying drawing, that the present invention provides a new and improved dusting device having the desirable advantages and characteristics, and accomplishing its intended objects, including those hereinbefore pointed out, and others which are inherent of the invention.

I claim:
