4 Claims.

This invention Vrelates to -a novel cleaning -device `adapted lto clean wallpaper, vwwalls, window shades, upholstered furniture, draperies, and the like.

Oneof the objects of this inventionis to provide a ycleaning element which can Vbe used in combination with a -conventional Iholder, such as a mop holder, or the like.

A further object lof this invention is `to lpro- `vide ra 'core -or forming element about ywhich a cleaning substance, `such as for example, a sheet of sponge'rubber, may be wrapped Aand rmly -secured thereto, so 'that a firm cleaning surface may be presented.

A 4further 'object'frela-tes to the novel Yshape of vthe core which facilitates A'the use vof the device at a large variety of angles kagainst the nsurface ito "be cleaned, from to 180, the 'benefits of lwhich will be readily Iappreciated and `found necessary in cleaning -walls and ceilings,` and the angular variation further prevents an entire surface 'of the cleaning element from immediately becoming saturated with dirt, as is the case with cleaning elements presenting at surfaces.

Other objects relate to the economies of construction, eiciency, novel structure and arrangement of parts, as Will be apparent from a consideration of the following description and drawing, wherein:

Figure 1 is an elevation of a conventional mop holder, which may be used to clamp and retain Amy forming core and cleaning element.

Figure 2 is a side View of a preferred form of core or forming element, and,

Figure 3 is an end view thereof.

Figure 4 is a perspective view of a sheet of sponge rubber which may form the cleaning element.

Figure 5 is an end view of the core with an edge of the sheet of sponge rubber attached thereto for convenience in application.

Figure 6 is a fragmentary end view of the holder illustrating the seating of the core on the bail of the mop holder, and the manner of application of the sheet of sponge rubber about them prior to being clamped.

Figure 7 is an elevation of the completed cleaning device showing the core and rubber sheet clamped in the holder, and,

Figure 8 is an end view thereof.

Figure 9 is a pictorial illustration of an application of the cleaning device.

Referring to the drawing, 10 indicates a mop stick set into the socket II of the holder, the

lower end of the socket being formed in a sub- `stantially U lshaped clamp I2 having a double clamping edge. Secured yto the upper edge -of the ysocket vis a spring I3, which carries a collar I4 slidable on the mop stick. Pivoted -to the collar is the locking lever IB, 'to :the center of J5 which is pivoted the 4ends of the bail I5. In the form of mop holder shown, the bail l 5 is movable towards the clamp I2, which is fixed, and when the locking lever is turned' upwardly from the position shown Vin Figure l, the bail is drawn 10 towards it to clamp a cleaning element between them, with 'the assistance of the spring, as shown -in Figures "I and 8.

vIt is to be understood, however, that while I have shown one form of mop stick and holder L5 in the drawing for the purpose of illustration, I do `not wish to be limited thereto, as various forms of holders embodying the same essential elements may be used equally -as well. lFor ei:- ample, other mop holders which kmay be obtained '20 on the market as readily vas the form shown, `have the bail "affixed -to the handle socket, and have a clamping element which moves towards the bail by means of a screw arrangement, and without a spring. Another form may have a fixed bail and a movable clamp, the clamp being urged towards the bail by means of an extension from the holder socket pivoted at the ends of the bail. It will therefore be understood that in this description of the operation of my invention, that the clamp I2 may be fixed Vor movable, and that the bail I5 may be fixed or moveable. Further it will be understood that when the bail is referred to, it is meant to partcularly denne the transversely extending portion thereof which is adapted to extend parallel with the clamp I2 and to be aligned between the edges.

Figures 2 and 3 illustrate a preferred form of core or forming element, which is preferably a solid structure and substantially semi-circular in cross section, although other forms presenting a smooth or curved surface I1, may be used, and a flat base I8 is preferred. Bi-secting the surface I'I and extending longitudinally of the core is a groove or seating slot I9.

The cleaning element per se, may consist of a sheet of sponge rubber substantially rectangular in form illustrated in Figure LLand it may be attached by staples or in any other convenient manner to one edge of the core base adjacent its center as at 2B, shown in Figure 5. This preattachment of one edge, while not essential, assists in applying the sheet about the core as will be further shown.

The core may then be seated on the bail I5 by ment or sheet of sponge rubber are clamped b'e tween the clamp and bas-e of the core.

It will be readily seen that since the handle extends radially from the core in the completed assembly, and due to the curvilinear outersurface of the core, it may be used against a surface to be cleaned at various angles and froml various positions with equal eiciency.

While I have shown and described the preferred embodiment of my invention it will be obvious to one skilled in the art that various changes may be made in the details thereof without departing from the spirit thereof, and I do not wish to be restricted thereto except as set forth in the following claims.

What I claim is:

l. A cleaning device comprising the transversely extending bail and head clamping portions of a mop-holder or the like structure, in combination with a core having a central longitudinal slot therein adapted to seat said bail, and a sponge rubber cleaning element adapted to be extended around said core and said seated bail to encircle said core and thereby cover said bail and to be clamped by means of its opposed longitudinal edges onto the core by said head portion.

2. A cleaning device comprising a transversely extending bail and head clamping elements of a mop-holder or the like structure, in combination With a substantially semi-cylindrical core having a slot bi-secting and extending into the convex face thereof and adapted to be seated on said bail thereby, and a sponge rubber cleaning element adapted to be extended around said core and said seated bail to encircle said core and thereby cover said bail to have its opposed longitudinal edges clamped against the plane surface of said core by means of the head clamping element.

3. A cleaning 'device comprising the transversely extending bail and head clamping elements of a mop-holder or the like structure, in combination with a substantially semi-cylindrical core having a slot bi-secting and extending into the convex face thereof and adapted to be Aseated on said bail thereby, and a rectangular sponge rubber cleaning element having one of its longitudinal edges secured to the plane surface of said core, the free edge thereof being adapted to be extended around said core and said seated bail to encircle said core and thereby cover said bail and to be clamped tor the plane surface of said core by means of the head clamping element. 4. The combination with a conventional mopstick or the like structure having transversely extending clamping elements comprising a bail and a clamping head relatively moveable to clamp an object, of a Wall cleaning device comprising an elongated core having a substantially semi-cylindrical cross-section and provided with a longitudinal slot extending into and bi-secting its convex surface and seating therein the bail, a rectangular sheet of sponge rubber having one ofA its longitudinal edges secured to the plane face of said core and being stretched around said core to encircle it and thereby cover the bail, the opposed longitudinal edge of said sheet of sponge rubber being clamped to the vplane face of said core by the clamping head.
