My invention relates to apparatus prima arra'n -rily designed for use upon fiofors and involves anvassociationof devices capable of effectually cleansing, waxingand polishing the surface under treatment.

Generally stated, myimproved floor cleaning and-polishingdevice has for aprincipal feature the provision of a plurality of means which can beeasily afliXed to the deviceto' aceompli'sh the several purposes of the invention, each means being particularly well adapted to detachablyvfit the device and bej operating handle shown removed. I

ing provided with comparatively simple connecting parts-tor readilyeflecting the attach-, ment and removal of the respect ve means according tothe n'atureof the work being done, Pz'trticularly stated, the invention hasfor an, object theprovision of a compact floor cleaning apparatus involving a detachable brush section,an endless wax applying memher to which-the Wax or othermaterial is-in turn applied from a self-contained reservoir,

and: a detachable polishing member in the nature of a strip of cloth which is preferably afliXed to the apparatusover the brush sec tion. 1

Another object of the invention is to providea floor treating device of the class described, comprising a casing or housing having mounted'therein an endlessbelt'member adapted to intermittently frictionally engage the floor, and meansincludi'ng'a wax or other Y material compartment adjacent said endless belt and from which the wax or other material 4 is withdrawn by the movement of said belt when the device. is movedacross the floorwith the said belt out of 'frictionalengagement therewith, and

in rolling contact with the floor.- i

A further object of the: invention is to pro vide a floor treating apparatus including an endlessbelt member adapted to contact the floor and movable" in onedirectio'nas the apparatus is moved 1n one CllIGClJlOIl across the surface "being treated and provided with means for holdingsa'idendle'ss member in firied relation for frictional engagement with the floor as the apparatus 18 moved in'the opposite direction ,over the-surface under treatment, whereby a substantially uniform -application and rubbing'of the wax or other material upon the surface to be cleaned-or polished isetfected. v

Thetop dis provided forthe housing and-has connected thereto the operating handle 5. The lower end ofthe handle?) is 'deta'ch'ably mounted upon a pin 6 extending through upright portions of a U-shaped member 7 se- V The top 4 is preferably. provided with a {cover section 8 at oneend thereof, said cover section bei'ng removable topermit access tOthe'interiOr of v the "housing.

jacent the top l, andxthe hookmember 1() acts I r to holdsaid'cover section in place. "A link connection'in the form of a snap hook- 11 is utilized toanain'tain the handle the fl is a compartment or reservoir '12'ada'pted' {to receive fsuita le-"floortreating material proper inclination ;when moving the apparatus across the floor; i Thls construction permits the release of the handle, as will be understood. o y V Formed within the inter orof the casing such as wax, forexample. The compartment orreservoir 12 is preferably formed between theopposite side walls 2 of the casingyand vertically disposed partitions 13space'd' lonjgitudinally of the casing'and arranged adjacentthe t'op-4 tl 1ereof.- Other compartments 14 may be=provided intermediate said par titions Bland-the respective end walls 33 ofthe casing; fAny or all of these compartments maybe utilized to hold" any desired material although the! intermediate compartment 12 isprimarily designed to retain such material as floor wax. i

Adjacent thelcompartment or reservoir 12 f; and extending beneath the partitions 13' in closely spaced relat1on therefron'nis' an end- 'lessbelt member 15 formed'of cloth or other lsuitableflexible material capable ofreceiving the floor treating materlal and in turn applying the sameto the surface of the floor under treatment. The endless belt member is. designed to form the bottom of the-comp artr'nent V or reservoir 12and is periodically movable beneath said compartment whereby the Wax orother material can be withdrawn'in ad fhering particles to thesurface of the belt for conveyance to the surface being treated; It

will be notedthat the partitions 'll act to retain. the major portion of the floor treating material ,within the reservoir 12 but-that the relatively small opening or space provided bet ve'en the bottom of said partitions and the upper surfaceof the belt, perm-its thedischarge and withdrawal of'the material'when thebelt is'n'iovedf The endless belt member .1 s maintainedacross the bottom of the-co1n partment or reservoir l-2fby means of a belt supporting member .16, as clearly shown in Figuresb and 7'. :The member 16 maybe hcld in a; suitable frame 18 screws 19 and qused todetermine the relative'spacing of the upper surface of the belt fronrth lowermost edges of .the'partitionsi13, will be undep stood: I a.

The endless belt member 15, supported The cleat portion 9 serves to g retain the inner edge of the cover section ado- The lowermost rollers 17 areendless belt member beneath the-lowermost,

edges of the walls forming the casing 1, said endless beltprojecting through the lower open end ofsaid-casing a suflicient distance to permit the movement of theapparatus' acrossthesurface under treatmentwhen ap plying thefloor treating material to said sur face by means ofthe endless belt member, as shown in Figure 7.

a The endlessbeltgmember is'adapted a; be intermittently held for frictional engage-' ment with the surface under treatment when the apparatus is moved in one direction,"the Y means efiiectmg this holdlng' of the beltbeing automatically released to permit movement "of said belt when the apparatus is mo ved 1n the-opposite, direction. The means which I haveshown to effect this periodic holding and a I release'of the endless belt member'includes a shiftable member'20 supported upon the inner face of the "belt 15 and longitudinally move able Withirithe casing between the lowermost rollers 17 The member 20 is in the form of a wedgethe taper portion of which isfadapted to be moved between one ofthe rollers 17 and said belt for preventingmovement of the belt around saidfrollers, thereby effecting frictional engagement of the belt with the" iioor or other surface. It will bc noted that, a 7

upon movement of the app'aratus'in the opposite direction theshiitablewedge member 20 will be released by the movement of the belt upon the floor in jitsfree passagearound the,

roller 17 ,said shiftable member being cap able of being movedthe full distance between the lowermost rollers 17, as shown in full and dotted lines HiFlglii'G 7. -The contact ng-of" the relativelystraight face of the wedge member withone'ot the rollers 17', as shown in dotted lines'in Figure 7, does not act to prevent the continued free movement of the belt memberas the apparatus isdrawn across the fi'oor in the direction of the arrow shown indotted lines in said figure. g 7 v The detachable closuresection for the 'box like casing 1 includes a plate member 21 having projecting therefrom a plurality of brisbrush or SCYUlJblIlFi-pUl'tlOIll -Cut-awayportles or other means'capable of formi tions 22 are provided in said closure section lie 7 for permitting the lowermost roller-sand belt 1 member to extend therein when said section is appliedv to the casing; 1, as bestshown in Figure 5, Suitable i'l'pright members 123 are 3 preferably providedon the closure, section,

said members being herein shownin the form of angle plates and 'disp'osed' toform ajtight fit against the inner faces of the: end walls 33 of the casing; This constructionper- 5 mits of the principal strains incident to the scrubbingor brushing action being imparted to the walls of the casing which are best able to withstandthesame.

Attaching means is provided at each of the brush-lilce'closure section, said attaching means including; upwardly extending flexible members 24 ,the' upper ends'Ofwhich arede'signed to be bent around bailelikemem- *bers 25. The extreme ends of the attach ing members 24 are preferably reinforced or 1 thickened to extend beneath the 25 when the latter is pressed against the outer.

. walls of the casing, as best shown in Figure 5.

A bail member 25 is-slidabl mounted in" each end wall and comprises spaced armsQG passing through holes 26 and having their inner ends bent to prevent the complete withdrawal of the bail member-L The arms 26 are j preferably spring-tensioned against the side of the opening through which they passpso as to provide frictional contact between the arms and the adjacent contactingportion of the wall. This may be accomplished by flaring the'inner ends ofthe arms 26 when-in" their innermost position, the withdrawal'of the bail member causing saidarms to move toward each other andefiect frictionalen gagement.

The flexiblepolishingmember 27 is preferably adapted to be fitted over the brush tion of the closure sectionland contact the surrounding buffer 30 provided on the closure Section. The casing 1 may also be provided with a surrounding" buffer 31 which is exposed for use when the apparatus is used with the endless belt member contacting the'fioor,

-. as shown in Figure 7 In the use of my invention the; surface tobe treated may be first thoroughly cleaned with the'bru sh portion of the bot-tom closure section, whereupon the said closure section can 1 be. quickly detached by withdrawing the bails 25 and releasing the flexible attaching members 24. With this section removed the 'ap-' parat -us is positioned upon the floor with the endless belt member in contact therewith. 'Movement of the apparatus in one direction causes the belt member to freely move across the floor and in so doing convey to the sur face under treatment the particles of wax or other material adhering to said belt member. When the apparatus ismoved in the lopposite direction the slidable member 20 j causes the belt to be heldagainst rolling movement and maintains the same in relatively fixed pQSltlOIl' for frlctlonal Contact l with the surface being treated. These suecessive movements of the endless member serves to effectively apply a uniform quantity of wax or other material to the floor. The "bottomclosure section may now be reaffixed to the casing 1 and the flexible polishing member 27 positioned over said brush section and attached to the casing, whereupon bail member the surface to which the wax hasbeen I: i ,can now-be effectively" polished byiinoving V the apparatus across said surface.
