FLOOR WAXER.

Application filed August 7, 1925. VSerial No. 48,744.

My invention 'consists in an improved device adapted particularly for intermittently feeding liquid wax from an attached container and conveniently spreading the same upon a floor preparatory to polishing; and the novel and advantageous construction thereof is hereinafter fully set forth in connection with the accompanying drawing, and clearly defined in the subjoined claims.

Fig. 1 is a centrallongitudinal sectional elevation of a device embodying my invention in preferred form; an attached wax container or reservoir being indicated 1n dotted lines.

F ig. 2 is mainly a plan view of the same, indicating also the casing-connected handle; the valve being removed and a portion of the casing being broken away so as to revea-l the enclosed brush back.

The drawing indicates an ordinary brush having a wood back the middle bristles however being omitted, in line with a circular aperture 11 provided in the back; and the latter being provided with spaced apart 25 screw- posts 12, 12, by means of which the casing 15, her-einafter fully described, is movably secured to the back with springs 13, 13 interposed so as to normally maintain the casing at a determined height above fi'l the brush bacll The casing 15 is very economically andv satisfactorily made of die-shaped sheet metal. It comprises rectangular end and side walls 16 and 17 which loosely lit the brush 33 back 10.; a top plate 18 the intermediate portion of which is cupped so as to form a funnel-.shaped portion 19 depending loosely into-the aperture 11; and a hollow upward extension 20 concentric with the funnel portion 19 and forming in connection with the latter a discharge chamber 21, through which, and the aperture 11, liquid wax is delivered to the floor under treatment. This upward extension 2() of the casing, which is separately die-shaped and rigidly attached to the latter as indicated, has its circular wall so formed as tol tightly engage the mouth of a removable liquid-waX container or reservoir indicated at in dotted lines; while its closure plate 26 is formed with a central opening forming a depressed valve seat 27.

The valve 30 is provided with a stem 31 extending downward through the discharge chamber 21 into the back aperture 11. The valve 1s normally seated by a stem-enclosing spring 32 pressing against a fixed collar 33. As shown, the notched lower end 34 of the stenrhowever engages a supporting bar 35 provided in the lower portion of the back aperture 11; a bent wire secured to the back 10, conveniently forming such supporting bar,A and serving to maintain the valve 30' at a fixed height above the brush regardless of any relative downward movement imparted to the casing.

The liquid wax may be contained in the can 25 in which it is conveniently salable; the mouth 25a thereof being adapted to tightly lit upon the casing extension 2O so that when the can is in inverted position upon the casing it serves as a reservoir under control of the valve 80. As indicated the can is steadied and tightly held upon the casing 15 by means of a bail 38 pivotally connected to the latter; and a handle 36-3-7 is alsoy pivotally connected to the casing so as to conveniently serve both for moving the brush to spread the fed liquid, and for intermittently pressing the casing downward upon the brush to effect the feeding. This relative movement of the casing upon the brush compresses the valve spring 32 without changing the position of the valve 30 relative to the brush which supports it by means of the cross-bar 85, so that the liquid is permitted to flow downward through the casing Achamber 21 and brush-back aperture,

`11,to the floor, until the ldownward pressure upon the casing is removed. The construction of the device is as simple as its operation and very inexpensive.

What I claim is:

1. In a floor waxer comprising a brush having an apertured back; a relatively movable casing having a yielding connection to the brush back and said casing being provided with a valved discharge chamber forming a tapered reservoir-attaching upward projection thereon and a depending W0 LTI ing a dilcharge chamber with a depending 10 vfunnel portion slidable in said aperture and a valved upward exteneion of tapering forni adapted for SupportingV a separate liquid reservoir, said cae-ing having pi'voted thereto an operatingA handle and reservoir retaining means. Y

In testimony whereof I zi'iix my signature.

JAMES H. MLLHOLLAND.
