An important object of the invention is to provide a device ofthe abovementionedcharacter, having a large number ofuses, such as cleaning automobile upholstery, furniture upholstery, hats, clothing, drapes, tapestry,.handbags, luggage-suede shoes, spats, window shades, paintings, books, book-covers, chair seats and backs, formedof leather, fabric, or cane, and the like. A further object of the invention is to provide a device of the aboveeme'ntioned character, so;

constructed that the cleaning element will ,be properly supported in use, whereby the cleaning element will bodily flex, to accommodate itself to the surface'being' cleaned. I I i I A further object of the invention is to provide means whereby the cleaning element may be applied to the headfof A further object of the invention is to provide simple and reliable means for securing the cleaning element to the head and core of the device. I A further object of the invention is to provide a device of the above-mentioned 'chara'ctenhav-Y- ing one or more squarecleaning elements, which may be applied in four ways to the head and core, thereby increasing the life of the cleaning element and rendering the same more 'eiilcient.

A furtherobject of the invention is to so'construct the, cleaning element holding member or clamp, that the same is interchangeable, in a single or double device embodying two of such holding members. I Other objects and advantages of the, invention will be apparent during the course of the follow ing description. c T

This head, is provided upon its lower face with a longitudinal groove 2|, receiving the upper edge of a relatively thin, suitably stiff; flexible, and resilient core '22. Thisfcore has its upper edge held inplace [within the groove 2| byany' suitable means," such as nails 23, passing through one side of the head, asfshown. Y The core 22is .pref

erably formed of sheet fibre, althoughother'suit able material may be employed. As shown in Figures 51 and 8, the core may comprise an, outer U-shaped portion 24, reinforced by an inner portion or sheet 25. In'Figure 9, the core is shown @aslbeingformed of two U-shaped portions 26,

disposed in contacting relation. in- Figure 10,

the "coreembodies a U-shaped portion 21, and

inner portions or sheets 28, having their outer 'ends bentlaterally and inwardly, as shown at 2 9.' "In Figure 11, the core is formed of oneU-shaped; portionfiill. The core may also'be formedof a "plurality of sheets 3| and 32,arranged in contactingrelatio'n, with the sheet 32,being,disposed innermost Figure l2.- In Figurefl3, the core is formed of a single sheet 33, which is'somewhat heavier. In all forms of cores, the same are suitably stiff, flexible and resilient, and they may beformedof fibre, as explained. I Mounted upon the top of the head 2llis aresilient holding member 34, formed of metal, or thelike. This member is generally U-shapedin cross-section and embodies a base 35, which is attached to the top of the head 20 byv screws 36, and sides 31. These sides are provided at-their lower "or freeedges, with inwardly bent jaws or flanges 38, disposed at substantially a right angle to the sides 31; as shown; The sides 31 are proof these U -shaped .clips may be .slightly flared,

outwardly, if desired, although this flaring may be omitted.

The sides 3'! carry clamping extensions 44, preferably formed from a rod or wire. These clamp ing extensions are rigid and are angularly dis posed and have shanks 45, which extend within, the sides 3'5 and are rigidly attached to the jaws or flanges 38 by spot-weldingor' thefllke.

The numeral 46 designates a cleaning. element,

which is compressible and flexible, and is preferably formed of sponge-rubbers, 'I'his cleaning element is preferably in the form of a square, which is important, as it permits of ga four-way application of the cleaning element to the rcore and head. Thecleaning' element ,is longer than the head and holding member 34, and projects outwardly beyond-the same, as shown. 7

In the application of thecleaningelement 4G to the core and head, the clips or clamps 43 are removed from the resilientholding member '34, and this, resilient holding member is so tensioned that its sides3'l will automatically move to an open position, as indicated in Figurefi. The sides 3'! must be slightly further opened'by the-fingers, before the ends of the cleaning-element may be passed beneaththe jaws' 38, thereof. One side 3'! is now slightly further opened,and'one edge of the cleaning element .46 is passed 1 beneath the jaw 38, and this side 31 is released,,the jaw 38 of such side engaging with ,thecleaning element and pressing the same against the core 22, sufficiently to hold this edgeaof the cleaning element into position, while the cleaning element is completely passed about the core 22, and its .opposite .edge, in a similar manner, placed beneath the jaw 38 of the,,companion side 31. Both sides being now released, theiaws 3.8 will hold the cleaning element against dis-- placement. It will be noted .that the cleaning element completely encloses thecore 22,, and extends longitudinally beyond the same for .a substantial distance, and the upper edgesof the cleaning element abut against vtheshouldersproduced by the head 20, upon opposite sides of the core. The sides 37 are now moved inwardly by pressing the same together by the hands or'thejllke, until they substantially engage with the sides of the head 20, at which time the holding clips or clamps are placed into position. These clips may be arranged horizontally Within the guide passages 42, Figure l, or theymay be arranged verticallywithin the guide passages 4| Figure 7. When the sides .31 are thus held in the inner or closed posi tion, the jaws SBbecome embedded in. the mates rial of the cleaning element, andthe clamp extensions 44 also become thus embedded. By having the jaws 38 and clamp extensions. .44 embedded in the material of the cleaning element, and spaced from its, free edges, these partswill not contact with the surface being cleaned.

The device thus described may be used without- .a handle, the operator grasping the head 20 in the hand. The cleaning element may be rubbed over the surface tobe treated, either transversely, longitudinally or diagonally. 'Ihecore will pere mit of the proper flexing of the cleaning element, which may have its edge or side moved over the desired surface, as clearly illustrated in Figures 1''! and 18.

Figure 19 shows how the device may be used in a corner.

In Figures and 16, I have illustrated a modification of the invention. In these figures, a head 29' is provided, corresponding to the head 20, but elongated. .Secured tothe ,intermediateportion of the head by'meansoia bolt 4:! or the like, are jaws 48, rigidly secured 'to a sleeve or ferrule -49 receiving one end of a handle 59. Two of the "holding members 34 are mounted upon the head 1B1, upon opposite sides of the sleeve 49, engaging with cleaning .elements 46, surrounding the cores '22. All'otherpartsof the device remain identical with those shown and described in connection with the first form of the invention. The outer clipsor'clamps 43 may be horizontally or vertically applied, while the inner clamps must be vertically applied, as shown. v

.. In view of the foregoing description, the operationsand use'of the second .form of the invention isthought to be obvious. I
