Each holding element 23 carries a clamping element or rail 28, in the form of a channel, and is thereby U shaped in cross-section, with its open side arranged inwardly. The rail or channel is provided in its opposite sides with apertures for slidably re ceiving the ends 25, whereby the rail is shiftable transversely with respect to the holding elemenm, p -i Means-are provided: to holdthe elements 24in the closed 'position,comprising transverse plates 29, provided at its opposite ends with upstanding curved lips 30. The transverse plates are mount ed upon spacing elements 3|, whichin turn,pare carried by lower transverse plates 32, the. entire unit being attached to the head l5 by a screw 33, or the like. Thelower plates 32 ,prpjectbeyond the sidesof the head 15, for a substantial distance, as shown. Meansare provided to connect. a handle vith the head l5, comprising a pair of spaced plates "34, having plates or.-bases,35 attached to their lower ends, and these plates 35 project beyond the opposite facesofthe. head 15, for asubstan Jtial distance, as more clearly shown in Figure 5. The plates or bases 35 are rigidly attached to'lthe headlS. by screws 36', or the like.

The plates or knuckles 34 have (their edgesv converging rearwardly and these edges hav notches liltoreceive the sides 24" of the holding elements.

The numeral Q45 designates cleaning element sections, which, when "assembled, produce 'a cleaningelement carried upon ,the core 2!} This cleaning: element maybe formed of: sponge rubsenor, other 'suitable material. Each cleaning :element'ispref erablya square,.and this enables the sameto be mounted fourlways upon the core,

' for increasing capacity and longer life.

In applyingv the cleaning elementstdthe core :20,- both holding elements 23 being in ,the open position, at substantially a right angie" to .their closedgposition, when cleaning element section 45 has its end presented. to. theholding element 23, :the outer corner of thecleaning element ,;is pulledthroug'h. the .u-shaped extension 2G, the entire end of the cleaningleleinent.being then passed into the holding element' and beneath the clamping rail 28, whichhas' previously been shifted to' the outer.

In a similar manner, the opposite ends of the cleaning elements 45 are arranged Within the holding element and clamped thereto upon the head l5. When it is desired to remove the cleaning element sections, the side24 of the holding element is sprung inwardly and upwardly to clear the locking ribs 30, when the holding element may be swung outwardly.

I With'lthe cleaning element sections assembled upon the resilient core 20, such cleaning elements may be properly moved or rubbed over the surfaces to be cleaned. The core 20 being normally cylindrical, the cleaning element sections will be Howcontact between the cleaning element sections and thesurface to be cleaned, pressure is exerted upon the handle 38, which pressure is transmitted to the; resilient core zdcausing this core to be'flexed and thereby have the contact portion thereof flattened. Th'e strips 22 may flex in either direction, depending po the application of pressure aslshown in Figure 13. Fur- ,theyare covered and prevented from contacting withfurniture, .oiwthe' like. These extensions also-permit of the head I5 being shortened, there by allowing the cleaning element sections to project longitudinally beyond the samefor a substantial" distance, keeping the head from contacting with objects. 7 The cleaning element is preferably formed in two sections, but theinventi'o'n'is in' no sense restricted to this feature. By. employing the cleaning element sections, they may be more conveniently manipulated and readily reversed so that their opposite faces may be It isto' be understoodth'at the form of my in"- yention herewith shown and'described is to be taken as a 'preferred example of the same, and that various changes inthe'shape; size and arrangement of parts may be resorted to without departing from the spirit ofmy invention, or the scope of the subjoined' claims.

Having fullydescribed my invention, what I 'claimas new is:f-
