A TTORNEYS.

.This invention relates to cleaning, dusting .andpolishing devices of the type whichjncludes a resilientapad forming abacking for a-removable. coveringmaterieland has for its principal object to provide a device. Ofbthis character wherein theresiliency of the pad isutilizedafor securing the covering material and/ or head to .which a handle may be attached.

Other objects of-the invention are to provide a. cleaning,

dusting and polishing device of. simple and irelativel-y inexpensive construction that is easily assembled 'andathe covering material retained without the use zoficlampsor other fastening devices.

A further object of the invention is to .provide a frame for containing: the .resilient material or pad-and ahead cooperating with the frame for engagingthe covering material.

In accomplishing theseand other objects .of..the, invention hereinafter pointed out, I have. provided improved structure, the preferred form of which is illustrated in the accompanying drawings wherein:

Fig. l is a perspective view of the-partswhichcomprise a cleaning, dusting and polishing device inv accordance ats aren't Thepad 3 may consist of a block of sponge rubber or similanresilient porous material havingsubstantially verticallyside and end faces ifs--14 and Its-16 and top and CLEANING, DUSTING AND POHSHINGDEVICE bottom faces 17and 18. The block ofresilient material is of a sizeto fit snugly within the flange portions 12, with the upper face 17 engaging the inturned flanges-10ofthe frame; In order to positively retain the resilient material, a suitable adhesive material 19 may be used betweenthe .outermarginal portion of the frameand the ,upper face of the resilient material asbest shown in Figs. 6 and 7,

the adhesive being, spaced from the inner edges 20 of the flanges10 so as to allow for engagement of the head 5.

The head5 includes a substantially rectangular plate member 21. conforming in shape and sizewiththe opening 11 in the frame 2. The transverse sides of the head have depending flanges 22 and 23 that pass through the opening of the framein substantially close.relation with the edges of thefianges 10, while the ends ofthe head have laterally directed flanges 24 and 25 which are adapted to be engaged .undenthe flanges 10 of the end bar portions 8 and 9 as later described. The edges of theflanges 22 and 23 have rounding ends 23 to prevent catching of the ends'of the flanges on the. pad 3 when the head is inserted in the frame. as later described.

The head 5 maybe provided on the upper facethereof with a knob-like handle 26. However, if thedevice is to sides 13 and 14- of the resilient pad 3 and to extend up and over the transverse bar portions 6 and 7 ofthe frame with the ends28 and 29 thereof closely approaching the transverse center of the frame 2 as shown in Fig. 2.

with .the present invention, the parts beingtshowncin of gripping the covering material at the ends of the device. I

Fig. 7 is a similar fragmentary section througharside of the device illustrating the manner of grippingttheends of the covering at the longer sidesof'the device.

Fig. 8 illustrates an adaptation ofithe invention to a floor mop or duster.

: Referring morein detail to the drawings:

1 designates a cleaning, dusting and/ or polishing device constructed in accordance with the present invention and which includes a frame element 2 carrying a resilient pad 3, a covering 5 adapted to be extended over the pad and frame, and a head 5 that is inserted in the frame for cooperation with the resilient material in retaining the covering.

The frame 2 is shown of substantially elongated rectangular shape having transverse bar portions 6 and 7 and end bar portions 3 and 9 preferably formed as an-integral part, the bar portions being of angle shaped cross section to provide a substantially flat inward flange 10 surrounding a rectangular opening 11 for receiving the head 5 as later described. The bar portions also include depending outer marginal flanges 12 for stitfening the frame and for surrounding the resilient material 3.

.be used as. a floor cleaning .and polishing device, the head will be provided with a bracket 27' for'attaching a handle 27 as shown in Fig. 8.

F The covering 4 may be of any.'desired'form but is shown; in the drawing as comprising a sheet offabric material having a sufficient size to cover the face 18 .and

* The'material of the covering 4 is preferably oflonger length than the length of the. frame 2 as shown in'Fig. 1 whereby the projecting material prevents the ends of the frame from striking or marring objects with'which the device may come in contact. .The covering'material may be of ordinary dusting cloth material or provided with' :arelatively long pile to better pick up and retain the dust or other elements when the device is in. use. The covering may also be suitably impregnated, for example, with a wax, oil, polish, an abrasive material, .oriother types of covering may be used: depending upon the use of the device.

' In assemblingthedevice, the frame 2 carrying the pad or block of resilient material 3 is placed ,upon the inner side of the covering as shown in, Fig. 1. The ends 28 and 29 of the covering are then drawn up substantially taut over the bar portions 6 and 7 'as shown at in Fig. 2. The head 5 is then applied by tilting the plate like bodythereof in the position shown in' Fig. 2 sokthat '=the =flange'25 pushes the ends of thecovering' 4 'under the flange it? of the bar portion 9 shown in Fig. 5.

The other end of the head is then brought toward the opposite end of the frame with the curved ends of the flanges 22 and 23 rocking on the pad... During this movement, pressure is applied in the direction of the inserted flange 25 so that that end of the head is depressed within the resilient materiala suflicient distance to allow the head to slide under the flange 10 of the bar portion 9. The flange 24 is then in position so as to clear v.the flange of the end bar portion 8 of the frame, after which the head is slid retractively to bring the flange 24 under the flange 0f the bar portion 8 and return the flange 25 under ate with the resiliency of the pad 3 to provide the gripping necessary to retain the covering material.

The device may he used in conventional manner with the resilient material retaining the covering inyielding Contact with the surface to be cleaned while the storedup action in the resilient material firmly holds the covering in position during the use of the device.

Whenthe covering is to be removed for cleaning thereof or for replacement, one end of the head is depressed into the resilient material a suflicient distance so that the opposite end may be slid from under the overlying flange of the frame, after which the head is readily withdrawn from the frame to free the ends of the covering. The covering may then be readily removed for cleaning or it may be replaced with a new or diiferentftype of covering. t t

From the foregoing, it is obvious that I have provided a cleaning, dusting and/or polishing'ldevice which is of simple and inexpensive construction and wherein the resilient material of the pad 3 functions to eflfect grip of the covering material 4 with the frame 2 and head 5 of the device.
