noon waxmq AND Application illed May 17,

This invention'relates to floor waxing and polishing machines and has for one of its objects to provide a machine of th1s character which will be simple in construction,

comparatively inexpensive to manufacture and more efficient in use than those which have been heretofore pro osed.

A further object of the nvention is to provide a machine of the class described 111 which the driving motor is housed in an isolated chamber to the end that it may be protected from the dust and wax particles which are necessarily thrown ofif by the rotatingwith a layer of wax which has necessitated a cleaning ofthe machine every time it 1s used,

With the above and other objects in view which will appear as the description proceeds, the invention consists inthe novel details of construction andcombinations of parts more fully hereinafter described and particularly pointed out in the appended claims. 1

Referring to the accompanying drawings forming-a part of this specification in which like reference characters designate'like parts in all the views:

by the line 4-4 of Fig. 3, looking in the direction of the arrows; Fig. 5 is a top plan view of the machine as shown' in Fig. 1; I

Figs. .6and 7 are respectively side eleva- 65 tional and end? elevational views showing in detail, the motor mounting; and,

Fig. 8 is a longitudinal vertical sectional view through the frame or housing with the motor and-brush omitted-and taken a proximately on the plane indicated by t e line 8--8ofFig.3. v Referring to the said drawings the numeral 10 indicates generally the housing of the machine which comprises a central main sec- "tion 11 and the laterally offset portions 12 r and 13. The sidewalls of the said sections 12 and 13 extend forwardly and have mounted therein, a shaft 14 which is preferably retained in place by the bolts or screws 15, as will be readily understood. The ends ofthe said shaft are reduced as at 16 to receive the antifriction bearings 17 upon the outer races of which is mounted the-drum of the brush 18 which is provided with suitable tufts of bristles 19, as will be clear from As will be noticed from Figs. 3 and the brush 18 at one end, extends close to the wall of the offset portion 12 while at vits other end, it is provided with a pulley 20 around which passes the belt 21 for driving the brush.

The housin 10 is provided with a transversely e'xten ing partition wall 22, see Figs.

2, 3, 4 and 8, which divides the said housing into a brush chamber 23and a motor chamber 24. The said partition wall 22 is imperforate except for the opening 25 pro-"- vided within the. offset portion 13 and through which the driving belt 21 is adapted to pass, as will be readily understood from the drawings.

A motor 26 is mounted'in the motor chamber 24 in any suitable manner but preferably I by means of the pendulous suspension shown :in detail in Figs. 3, 6 and 7. This suspension as will be clear from the said figures, comprises the reversely positioned U-shaped strap members 27 and 28 carried respectively A by the main portion 11 of the housing and p -the motor 26, with their ears 29 and 30 piv otally connected by means of the rod or shaft I 31 extendin therethrough.- An L-shaped imperforate except for the opening so that the motor chamber 24 is substantially completely isolated from the brush chamber 23. It therefore follows that the said chamber 24 and the motor 26 are completel protected from dust andwax particles t rown off by the brush 18, except for the said opening 25. In order to prevent such foreign matter from finding its way through this opening, there is provided a longitudinally extending wall 36 running forwardly from the transverse partition 22 in close proximity to the lower end of the brush 18, as viewed in Fig. 3. This said wall '36 is cut away as at 37 to closely follow the contour. of the drum of the brush 18, (see Figs. 2,

3 and 8,) and it therefore follows that dust and wax particles will be prevented by the said partition wall from finding their vway' through the belt opening 25 in the transverse wall 22 so that the motor will be completely protected from such foreign matter.

In rior machines of this character it has been ound'that the heat necessarily generated by the operation of the electric driving motor has been so great that the wax par ticles thrown off by the revolving brush. have been melted upon the various parts of the machine and fused into. a solid coating covering such parts. It has, therefore been necessarywith the prior machines to scrape off or otherwise remove this wax coating each time the machine is used, which operation has been exceedingly diflicult and disagreeable.

order to overcome this objection in the present instance, means are-provided not only for excluding wax particles from the motor chamber butalso for efficiently ventilating and cooling said motor. As will-be clear from Figs. 3, 4, and 6, the driving shaft 34 v of the motor 26 is provided on the end opposite-to that carrying the driving pulley '35, with a fan 40 and the side walls of the housing 10 are provided with suitable ventilating openings 41 through which cool air may be drawn and discharged by the action of the said fan 40 thereby effectively dissipating the heat necessarily generated'during the operation of the motor. The dis.-

.sipation of this heat naturally will prevent the melting of any wax particles which may be deposited anywhere upon the housing 10 and it therefore results that the cleaning operations above mentioned need not be performed as frequently with "the present machines as is the case with the prior machines. I

A portion of the air blast from the fan 40 will also be discharged through the opening 25, thereby further preventing the entry of foreign matter into the motor chamber through said 0 ening.

In order to a 0rd access to ber 24, a removable bottom late 42 is provided which is normally held in position by suitable screws or other fastening means 43 engaging the ears 44.

For manipulating the machine, handle 45 is the motor champrovided, which may be similar to the well known vacuum sweeper handle and which carries the conducting wires 46 for supplying current to the motor 26; The said handle may be provided with a control switch 47 and with suitable clips or brackets 48 upon which the electric cable may be wound when notin use.

It will thus be seen that the present invention provides a floor waxing and polishing machine wherein the motor is mounted in an isolated chamber where it is effectively protected from dust and wax particles and that means are provided for ventilating and cooling this chamber to the end that the heat generated by the operation of the motor will not melt the wax and cause the formation of a coating of wax upon the housing. It will also be clear that owing to the peculiar constructionwhereby one end of the brush 18 is brought into close proximity with" the side wall of the offset 12 that the machine may be rangements of parts without departing from I the spirit of the invention and therefore it is not wished to be limited to the above except as may be required by the claims.

What is claimed is 1. A machine of the class described, comprising a housing having a, transverse partition wall dividing it into a brush chamber and a motor chamber, said wall having an 'opening therein; a brush mounted in said brush chamber; a motor mounted in said motor chamber; driving connections between said motor brush passing through said opening; and a second partition wall disposed at an angle to said firstwall and extending into said brush chamber, adiacent one end of said brush, said second wal being cut away to conform substantially to'the periphery of thebrush drum, for preventing foreign matter from passing to said motor chamber through said opening.

A machine of the class described, colnprising a housing having a transverse part-ition wall dividing it into a brush chamber and a-motor' chamber, said wall having an a brush mounted in said opening therein; brush chamber; a motor mounted in said motor chamber; driving connections between said motor and brush, passing through said opening; a second partition wall extending forwardly from said transverse Wall into said brush chamber, coacting with said brush to prevent foreign matter from passing through said openinginto said motor chamber; and a fan in said motor chamber driven by said motor, adapted to force air throu in said opening into said brush chamber, an thereby also prevent foreign matter from passing through said opening into said motor cham- 3. A machine iii the class described, com
