This invention relates to a iloor waxing device more particularly for waxing and polishing floors and the like in domestic establishments for example.

The invention aims to provide, among other objects, a relatively light-weight portable device for this purpose which may -be manually operated ywithout the need for any other power means and in which the application of the wax to the floor may be optionally controlled by the operator while the device is in motion and with a minimum of effort on the part of the operator, while simultaneously, the device continues to polish the oor to which the wax is continuously or successively applied as desired.

The machine of the present invention provides a remarkably simple and inexpensive device `for this purpose, which may be I produced in quantities at relatively low cost and which may be handled by the householder in much the same Iway las the old-fashioned carpet sweeper.

These and other objects and advantages will be apparent from the following descripting, taken together with the accompanying drawings, of an illustrative device embodying the present invention, and in which drawings- Figure l is a plan view with parts broken away for purposes of description;

Figure 2 is a somewhat side elevational view but shown principally in section taken on the line 2--2 of Figure 1; and

Figure 3 is a detailed view showing one of the bearings for journalling the shaft of the applicator brush and being a section taken on the line 3-3 of Figure 2.

Referring in detail to the illustrative construction shown in the drawings, the device in general comprises a main frame IB, an auxiliary frame I I, and an operating handle I2. The main frame I is mobile as by being carried in this instance by two pairs of wheels, one ypair being indicated by the numerals I3 and I4, and the other 'pair by the numerals I5 and I6. The front pair of wheels I3 and Ill mount the front axle I'I, which is journalled, prefer-ably by ball bearings as at I 8, in the side walls I9 of the main frame. Similarly, the rear pair of wheels I 5 and I6 mount the rear ,axle 23, which is journalled as by @ball bearings 2l also in the main frame side walls I9.

Forward of the front pair of wheels I3 and I 4,

the main frame carries 'a polishing roller 22 which is faced as at 23 with a soft material such as felt, and which is adapted at all times to contact the oor such `as 24 upon which the device may be operating. The polishing roller 22 is carried on an axle 25, `which is journalled in a cylindrical bearing block 26 at each end of the axle, las by a ball bearing 2l. Each cylindrical block 2S is rigid with a bearing stem 28 which extends upwardly and threadedly through a knurled thumb nut 29 which is rotatable above the top wall 3l of the frame I0. The bearing stem 28 passes freely through a grommet 32 fixed in an opening 3l) in the main wall 3 I. The grommet is secured on the under face of the wall 3l 'at 33. Thus, since the bearing stem 28 is threaded as at 34 to mate with corresponding lthreads 35 in the bore of the nut 29, rotation of the nut lwill raise or lower the axle 25 with respect to the frame I0. A conical coil spring 36, through which the bearing stem 28 passes, bears at its upper larger end against the under face of the frame wall 3| and at its lower smaller end against the cylindrical bearing block 25 and resiliently retains the axle 25 in vertically elongated slots 3l in the frame side walls I9. Thus is provided a floating resilient suspension for the polishing roller. This resilient arrangement accommodates irregularities in vthe floor 24, such as the edge of linoleum, or a threshold, and `permits the polishing roller 22 to rise in that case with respect to the frame Ill without the entire device being raised. The thumb nut 25 permits the polishing roller to be lowered to accommodate for wear therein, the spring 36 following the axle downwardly and main-taining a downward pressure on the axle, and this pressure is then adlustable.

A spur gear 38 on the inner face of the front wheel I4 meshes with another spur gear` 39 on the @axle 25 to rotate the polishing roller 22 at all times when [the device is in motion. The gear 38 is larger than the gear 39 so that the polishing roller` -will rotate faster than the wheels I3 and I4, and in the opposite direction, as indicated by the arrows A for the wheel and B for the polishing roller.

The auxiliary frame I I is pivoted as by bracket extensions 40 thereof on the iront main frame axle Il, for upward and downward movements with respect to the main frame under the influence of the ioperating handle l2 as desired by .the operator and for the purpose next described.

The auxiliary frame Il carries a rotary applicater brush el. The drum e2 which is carried on an axle d3 of the brush is journalled at each end in a cylindrical bearing block it which is rigid with a bearing stem 115 which passes freely through a grommet lli in the upper wall Ila of the auxiliary fname. 45 is threaded as at il to pass threadedly through the knurled thumb nut d8 on the upper Iside oi the frame wall llo. The coil spring 4S, through which the `bearing stern passes, presses at its upper end against the under face of the frame wall face lia and at its lower end against the cylindrical bearing block lill. Since the outer ends of the axle i3 pass vthrough vertically elongated slots 5d in thte auxiliary frame sidewalls 5I, the axle i3 may move limitedly and resiliently t upward or downward ywith respect to the auxiliary frame to accommodate for irregularities in the oor 2Q, similarly to the polishing roller 22, when the rotary applicator brush is caused to "engage the floor as next described.

The rear wheel iii carries a spur g aref/ upon. its inner face which meshes with another smaller` spur gear 53 fixed on the axle 43 oi the rotary applicator brush when the auxiliary frame is lowered from the position shown in full lines in Figure 2 to a position shown in dotted lines, in Figure 2 as at 54. Thus at the latter time, the applicator-brush 4i is caused to rotate at a speed faster than the rotation of the wheels HS. 'l5 and it, and in the opposite direction as indicated bythe arrows A for the wheel and B for the rotary brush.

The rotary applicator brush di is adapted to contact a'cake of a polishing material such as solidified wax 55 which is received in a compartment 5t formed inthe hollow uonerpart '5l of the vauxiliary frame li. A door' 53 hinged as at 59 on the upper side of the arxiliarv frame provides access to the compartment 5e. the knob `60 being provided for manipulation of the door or cover plate 58. The compartment 55 is onen at the lower end so that it communicates with vthe brush si, and thus the wax cake y55 rests in part by gravity on and in contact with the bristles of thebrush ii at all times both kwhen the 'i brush is stationary in elevated position as shown in full lines in Figure 2, and also when the brush is lowered to contact the iioor as indicated in dotted lines and as already alluded to.

To assist the action of gravity in holding the wax in Contact with the brush, I provide a resilient plate 6l which is carried by a pair ci conical coil springs t2, one at each end ofthe plate,

4the smaller upper ends of which are anchored on pins E3 fixed-on the upper Wall 56. of the frame part el and within the compartment 5t. The plate Eil has a shank 55 which extends outwardly Vof and plays vertically in a narrow elongated slot a-cakevof wax is being inserted. When the nut.

'68 is loosened, the plate Si is free to `follow the wax bar or cake 55 downwardly and maintain a pressure on the calze urging it into contact with the rotary brush 4|.

The handle #Zmayhave a reduced lowerpart- The upper end of the bearing stem -ishing roller 22 'lll by which it is tted snugly into the tubular extension 'H arranged centrally of and xed to the upper wall tl of the auxiliary frame part 5T, a screw bolt 'I2 securing the handle therein.

In order to limit swinging movement of the auxiliary frame l l to a point where it will not rub against the rear axle 29 but will still be free to engage the floor, the auxiliary frame carries a lug 'i3 projecting from one of its sides, as here shown in the upper part of Figure l, to engage the upper wall 3i of the lmain frame ill and act as a stop member.

By providing two of the adjustment nuts 29, one at each side of the main frame, and also two adjustmen'tl nuts 48, one at each side of the auxiliary frame, an inclination transversely of the lframe may be given to either or both of the poland applicator brush di, to acv `cominodate `further irregularities which there Cil the cake to the floor 24.

may be in the floor being Worked upon.

As est seen in Figure 3, which shows details of theresilientiioating suspension for the axle of the applicator brush (and which is similar to that-forithe polishing roller), the roller bearings may be inserted into the bearing block M, for example, by providing-the axle liwith: a reduced end ifi. After the axle is located.inthebearing block fil and the balls Zlalso located in-their race 15, one-half of which is in the axle 43, the sleeve it, in the inner end-of whichis formed the Yother half of the race 15, is then secured over the reduced end T4 of the axle and-riveted to be rigid therewith as at ll'. In this instance, the gear v13 may be carried rigid with sleeve le.

VBetweenthe nuts the upper wall Ha of the auxiliary frame ll is desirablyarched as at vl ib to'coniorm to the rotary brush l.

In order to enhance thetraction of the wheels i3, "le, i5. and it, they are desirably provided with rubber tires SQ having embossed treads So constructed and arranged theoperator may readily propel the device alongthe floor by-pushing it throughfthe medium of the handle livhile at the same Vtime steering thedevice as desired.

- Either continuously or at optional intervals, the

operator may lower the auxiliary frame yli with respect to the main frame l on itspivot as de scribed, to cause the'brush fllto engage the ioc-r. When the auxiliary frame is thus lowered, the .gears 5-2 and 53 will engage and the brush 4i will be rotated to transfer particles of wax from During-the entire movement of the device, the rpolishing roller 2,2 continues to contact the oor, and to work the wax into the floor surface.
