Our present invention relates to machines for treating floors, and more particularly to novel machines for waxing and polishing fioors.

5" An important object 'of thepresent invention is the provision of 'a machine'by means of 'which ifioors may be waxedV and polished, regardless of their size or area, in

a i'elativelysl'ioi't space of time. y Y

Another object of the invention is to providev a machine to accomplish these results eithersolid or liquid wax, but We preferably .utilize solid wax, since the inherent qualities of solidwaX for polishing purposes arefar superior `to liquidV Wax, which of necessity has non-waxing substances therein.

We utilize, in our novel machine,l a rotary brush having a pulley on each end thereof, said brush being driven by suitable means, such aty belts, from pulleys mounted on a y suitable motor.

Another feature `of the invention resides in carrying the vweight of the machine on rolling elements, the brush contacting withV the floor but not being subject to the pressures and strains whichv would be present if the weight of the machin-e were borne by the brush. This `greatly* relieves the loadl carried by the motor, and enables the use of a relatively small motor. to cause the high speed of rotation of the brush required for efficient waxing and polishing.

Another feature ofthe invention resides in providing a novel motorsupport, wherein .the motor is mounted on a pair of pivots.

suitable size and strength to swing the motor proper `tension .on the brush drivingbelts.

A further novel feature ofthe present in- Said brush is pivotally mounted in such manner as to permit of slightv vertical oscillation thereof. Thus, when an obstruction is encountered on the floor during the waxingor polishingV operations, the brush will IJur present machine is capable of use withv Bearing against the motor isa spring of be raised thereover, without injury to the brush, and without detracting from the waz:- ing and polishing actionof the brush.

Another object of the invention is the provision of' means'to heat the wax to lthe desired degree to permit said wax to i'iow through the machine and onto the brush.

A y'still further? object of the invention resides in the provision of means whereby the brush itself will aid and assist in the feeding` of the waxto said brush.

Anotherand important object of the invention i's-to provide means for properly distributing the molten wax over the surface of thefbrusli prior to contact of the waxed portion of the brush with the Hoor.

A further feature of the invention resides'in providingnmeans to eect a prelimiminary cleaning yof the brush each poi-,L

'tion of the surface Aof said brush leaves the floor, this preliminary cleaning means removing lint or any large pieces of dirt from the bristles of trie brush before reentry into ther machine those parts' of the surface of the brush which have contacted with'the floor. n

Another feature resides in the provisionof means, such as a scraper, arranged to engage the outer edgesof the bristles of the brush and effect'ainal cleaning of the same before sai-d bristles engage vthe wait openings or nozzles.,y Thus the bristles of the brush will be clean and inproper condition for assisting in drawing the wai: from the feed openings.

Anotherobj ect of the invention is the provision of vnovel means to control the feeding of the -molten wax from the waX pot tothe brush.` This controlling means ymay beV manually or pedally operated. y

Another feature resides in the provision lof means to control the amount of wax which flows into the said feeding means.

`A still further` featureof the invention consists 4in'having. the switches for. control yof the motor,.as well as for the control of the wax heating unit, on an operating handle within easy reachpof theoperator.V

Our present novel machine is efficient, coinpact, speedy of operation durable and rugged.` I

le believe that said machine, as above Vvention, features, details of construction,

combinations of parts, and advantages, will vbe hereinafter more fully pointed out,

described and claimed. Y

Referring now-to the drawings, illustrating a preferred embodiment of our present invention,

Fig. 1 is a side elevation of our novel floor waxing and polishing machine;

Fig. 2 is a front elevation of the machine illustrated in Fig. 1; y f

Fig. 3 is a longitudinal sectional view on the line 3-3 of Fig. 2;

Fig. Ll is a cross-sectional view on the line {l5-#l of Fig. 3, illustrating` the support; and Y F 5 is a perspective view, on an enlarged scale, of the wax feeding valve or tube and operating lever or handle therefor.

Referring now to the drawings, for a particular description vof the invention, its construction and operation, 1 designates a framev or hollow casing within whicha brush 2 is mounted on a pair of arms 3, said arms being pivotally mounted at 4 to the sides of the casing 1. The casing 1 is mounted on rollers or esters 5, and the brush-2 entends below the casing a suli'icient distance to Contact with the vfloor or surface being waxed or polished. Because of the pivotal mounting of the arms 3 carrying the brush 2, if an obstruction or unevenness is encountered by the brush in its passage over the floor, the brush may be oscillated a sufficient amount to prevent injury thereto, while at the same time efficiently Vand properly waxinfT or polishing the surface.

f The brush 2 is provided with'a pulley 6 at each end thereof. Pivotally mounted within the casing 1 is a motor 7 having at each end a pulley 8 preferably having a cork or other friction facing 9. A belt 10 is arranged eX- tending from each pulley 8 tothe cooperating pulley 6 on the brush, vsaid pulleys 8 being, of course, rotated by the motor;

The motor is pivotally mounted on screws 11 each having apointed end 1 2 seating in a recess 13 in the motor casing, screws ef;- tending through suitable bosses 11i in the casing 1 and being heldin properly adjusted position by locking nuts 15.

Abutting against the motor 7 and at one side thereof is an arcuate plate 16 having thereon a plunger 17,*'a spring 18 surrounding said plunger, and said plunger spring exerts pressure against the motor 7, swinging it on its pivot, andv constantly keeping the proper driving tension on the belts 10. It will be noted, from a glance at the drawpivoted motor dspring being seated in a suitable recess 19.1 rlhe ings, t -at the pivot point l of the arms 3 is above the center line of the motor 7, and that point of the brush 2 is bcloiY the center line of said motor Thus, pressure ofthe spring 13 against the motor will swing said motor about its pivot l2, thus forcing the brush l2 downwardly. lu this manner constant and elhcicnt'rotation or driving of brush 2 is assured as woll as pres.. i e on the floor or other surface being opera-ed upon.

Mounted within the casing 1 is a wax pot or wax container 2O secured to lugs 21 by screws 22. Fixed in a boss 23 in the wax pot 20 is a post 241- having its ,pper end threaded at 2:. adapted to seat over said post is a removable cover 26 having sh( uloers adapted to seat on nd a knob 27 is adaptto be screwed onto the post 24 to firmly said cover 26 in place, a gasket 28 being sed between the top of the fax pot :fl the lower rim of the cover 26. An arturo 29 is provided leadingfroni the wax ot 2O to a tube 30 having'an aperture 31 iercin adapted to be alined.y at the will. of the operator. with the aperture 29. A lever or handle 32 is provided at one end of said tube for rotating the and said lever may be operated either bv hand or bv foot. as delsired, to open or closed positiciin. or to any intermediate position. Y Y lili-:tending obliqu'ely through the bottom of the'wax pot 2O are a series of channels 33. and in the tube 30 are a plurality of apertures 34 adapted to be alined, on operation of the lever 32, with channels 33.

' he channels lead to a position where the wai; will be dropped onto the brush 2. A

the

" thorfof the ytop of the casing 1 a ed ysuitable electrical heating unit 3-lis arranged in the bottoni of the wax pot 2O and in close juxtaposition with the tube 30. Thus, when solid wax is ut, ...Zech asis preferable, the heating unit 3l will meltthe wax remaining in the tube first, and the heat will t ien permeate and melt the wax in the pot 20. A manually perated needle 35 is provide-dto control the Aow of the wai: through the aperture 29 to any desired degree.

Located under the wait pot 2O plate 36, this plate extending partially around and contacting with the brush 2 at 37. In the plate 36 are a plurality of openings 38, each opening having a lip 39 at one side thereof, thehrush 2 contacting with said lips, and, by capillary attraction, aiding the flow of thewax through the openii 38. The plate is arcuate v36 will effect an even distribution of the meltf ed wax over the face of the brushso that the surface of the brush willbecompletely waxed ralong its length before it contacts with the floorilltl. A plate al is attached to, the bottoni front ef the cas 1 and spaced slightly freni the surface of the brush 2. This present invention somewhat in detail, it will 1 insuring that the surface of the brush will be y cleaned before a new suppl'y'of wax is distributed thereover. Y

When it is desiredto merely polish the floor 40, after having waxed the same, the

lever 32 will be operatedto disaline the apertures 34 from the channels?) and thus, prevent the further flow of wax to the brush, said brush then beingrotated and acting merely as a polishing device. x

Suitable current conducting wires 43 lead from the heating unit 34 to a switch 44 on the hollow handle 45, the wires43 passing through said handle. Current conducting Wires 4G leady from the motor 7 through the handle 45, to a switch 47 yon thehandle 45.

Each 'of these switches'44 and 47 are within 53 on the casing l, and when the handle 45V is in upright position", said arms lwill snap into recesses 52 in said lugs 53, thus holding the handle 45 in its upright position.

It will be appreciated that we have devised a novel, simple, efficient, compact, and desirable machine of this character, and one which is possessed of many advantages .and features of utility. c
