FLOOB-SCBUBBING DEVICE.

Application filed March 28, 1925.

F0 (277 11171 cm it may concern:

Be it known that I, Amen J. GRABILL, a citizen of the United States, residing at lmler, in the county of Bedford and State of Pennsylvania, have invented certain new and useful Improvements in Floor-Scrubbing Devices, ofwhich the following is a specification, reference being had to the accompanying drawings.

This invention relates to floor scrubbing devices, and particularly to floor scrubbing devices in the nature of tanks mounted upon wheels and having scrubbing mops connected thereto.

The general object of the invention is to do away with the necessity of scrubbing floors by hand, which is most tiresome and back-breaking work, and to provide a ready, easy and simple means for scrubbing floors which comprises a tank adapted to contain water, a mop holder mounted upon the tank and movable therewith, the tank being mounted upon wheels and the tank being provided with a spigot or tap whereby the water may be discharged upon the mop or on the floor itself in measured quantities.

A further object is to provide a device of this character having a pivoted handle so that it may be readily pushed back and forth over the floor to cleanse the same, and which is provided with a relatively large opening in its top normally closed by a cover which may be used to catch. the water wrung from a drying mop.

A still further object is to provide improved means for supporting the mop, this means being particularly so constructed that two mops may be used or held in place.

Other objects have to do with the details of construction and arrangement of parts as will appear more fully hereinafter.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of a scrubbing machine constructed in accordance with. my invention;

Figure 2 is a longitudinal vertical section on the line 22 of Figure 1;

Figure 3 is a perspective view of the loweror wheel-supported frame;

Figure 4c is a perspective view of the tanksupporting frame;

Figure 5 is a perspective view of the mopsupporting frame;

Figure 6 a perspective view of the cl mp whi ngages th m p;

Serial No. 19,139.

Figure 7 is a perspective view of two mops showing the manner in which these are disposed within the frame.

Referring to these drawings, it will be seen that I have provided a supporting frame, designated generally 10, having wheels 11.. The forward end of the wheeled frame 10 is provided with two wheels 11. This frame is composed of longitudinal members 12 connected by cross braces 13. The handle 14 is connected to the frame 10, as will be described.

Detachably supported upon the frame 10 is a tank, designated generally 15, which, as illustrated, is rectangular in section and plan and which at its rear end is provided with a tap 16 whereby water may be discharged upon the mop. This tank may be formed in one pieceor in a plurality of pieces, and preferably the tank is provided with a relatively large opening-1r at its top having upstanding walls, which walls may be outwardly flared, and this opening is normally closed by a lid 18. This tank is held to a tank-supporting frame 19 composed of the longitudinally extending membe'rs 20 and the cross braces 21. These braces 21 extend beyond the longitudinally extending side pieces 20 and the tank is held upon this frame 19 by means of U-shaped straps 22 which are preferably made of galvanized iron, the lower ends of these straps being angularly bent, so as to rest upon the projecting ends of the braces 21 and be bolted thereto. These straps hold the tank firmly in place but permit its removal when necessary. The rear end of the frame 19 is formed by a transversely extending angle iron 23 andthe forward end of the frame carries a transversely extending brace 24: to which the handle 14; is pivoted, this'ha-ndle being bifurcated or forked so as to provide two arms which are hingedly connected to the brace 24, thus permitting the handle to be moved vertically.

Coacting with the angle iron 23 is a pair of flat bars 25 which are angularly bent at one end and which are bolted to the angle iron 23, these two supporting bars 25 extending downward and being provided with a plurality of bolt apertures. Bolted to these supporting bars 25 is a scrubber supporting frame consisting of members 26 which are angularly bent to provide vertical portions bearing against the bars 25 and bolted there to and a horizontal portion having transversely extending braces 27 having bolt holes in their extremities. Bolted over these transverse supports 27 is a rectangular frame 28 having bolts at its corners which pass through the projecting ends of the members 27 and the mop 29 is held between these transverse members 27 and the frame 28, with the yarn on the mop extending downward so as to come in contact with the floor. A double mop is used, as shown in Figures 2 and 7, with the webs of the mop disposed over the cross pieces 27 and with the projecting yarns extending downward between the cross pieces 27 and downward over the edge of the cross pieces. By having two mops, the strings of the mops do not have to be so long and yet the same results are obtained and the mop as disposed keeps inplace better by beingdivided than if it was one large mop. With this construction the mop may be raised or lowered to any desired height so as to bear upon the floor either lightly or heavily and the spigot 16 will discharge upon the mop itself.

In the use of this device, the tank is filled with hotsoapy water to any extent desired, the scrubber is then rolled onto the floor where it is to be used, and a small amount is turned on by means of the tap. The scrubher is then oscillated backward and forward over the floor so that the mop will thoroughly wash and scrub the floor. After the floor has been scrubbed in this manner and dried, another mop may be used for the purpose of getting up this water and giving a final finish to the floor. This mop may be wrung out through the opening 17 in the top of the tank. It will be seen that this will eliminate the necessity of carrying buckets of water and eliminate any tendency to slop dirty water on the floor, and that by its use just the right amount of water may be discharged upon the floor from time to time as it is needed, and when all is done the tank maybe readily wheeled out of the room instead of having to carry buckets of dirty water out. It is particularly convenient for charwon'ien and the like who have to scrub linoleum, marble floors and floors covering a large area.

Obviously the tank may be constructed so as to suit heavy work or light work and a heavy mop or alight mop may be secured by simply setting the scrubbing -1nop a little higher or a little lower. Preferably the wheels will be rubber-tired and the tank will be made ,of galvanized metal.

I claim 1. A scrubbing device of the character described comprising a wheeled supporting frame, a tank .detachably mounted upon the frame, a handle whereby the supporting frame may be shifted, depending members mounted upon the forward end of the frame, a mop support adjustably mounted upon said depending members for vertical adjustment, the mop support comprising a lower frame, and an upper frame clamped upon the lower frame and a mop engaged between said lilbi named frames.

2. A scrubbing device of the character described comprising a wheeled supporting frame, a frame resting upon the supporting frame and detachably bolted thereto, a handle pivoted to the last named frame, a tank resting upon the second named frame and having a controllable discharge device at its forward end, straps engagin over the tank and bolted at their ends to the second named frame, a mop-supporting means mounted upon the second named frame and extending downward therefrom toward the floor and vertically adjustable, and a mop carried by the mop supporting means.

3. A floor scrubbing device of the character described comprising a wheeled supporting frame having longitudinal members and transverse members, wheels carried thereby, a frame resting upon the supporting frame and having longitudinal and transverse members, the longitudinal members being bolted to the supporting frame and the transverse members projecting out beyond the longitudinal members. a tank resting upon the second named frame, yokes passing over the ends of the tank and detachably bolted to the projecting ends of the transverse members on the second named frame, said tan k having a discharge spigot, a mop support carried by the second named frame at one end thereof and beneath said spigot, and a mop on said mop support.

In testimony whereof I hereunto affix my signature.
