To all whom t may concern: y

Be it known that I, I-IATTIE E. LANE, of Colfax, in the county of Clinton and State of Indiana, have invented a new and Improved vScrubbing-Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a machine for scrubbingfloors or like surfaces so constructed that the machine will sprinkle or deliver water or a washing compound on the iioor, take up the water,` practically dry the floor, and deliver the material taken up into a receptacle forming a portion of the machine. l

Another object of the invention is to provide a machine of the character above set forth which will be exceedingly simple, durable, and economic in its construction.

lThe invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in both gures.

Figure 1 is a transverse section on the line 1 1 of Fig. 2, the brush being omitted; and Fig. 2 is a horizontal section through the central portion of the machine.

The frame of the machine may be of any desired construction. Usually, however, it consists of two side pieces 10, which have their forward ends carried downwardly, as shown at l1, and the inclined pieces 11 of the side portions are provided with a bearing 12 near the center and a second bearing at the forward end. A shaft 13 is journaled in the lower bearings of the frame, while an axle 14 is journaled in the upper bearing. The frame is connected near the front by an arched bar 15 and near the rear and center by cross-bars 16. I/Vheels 17 are secured to the ends of the axle 14, and one of the wheelsis provided with internal teeth 18, which teeth mesh with a pinion 19 on the shaft 13.

A receiver 20 is supported at the bottom portion of the frame by hangers 21, the receiver being provided at the rear with one or more caster-wheels 22. At the front lower portion of the receiver a lip 23 is formed, which is curved downward to an engagement `used to close the said nozzle.

with the floor, and the front or upper face of the lip 23 is concaved, and the front of the receiver 20 is likewise concaved, as shown at 24 in Fig. 2, the concavity of the front of the receiver being a continuation of the concaved surface of the lip. Near the upper portion of the receiver 2O a transverse opening 25 is made, and at the upper portion of the opening an inclined flange 26 is located, which extends downwardly within the receiver. A receptacle 27, adapted to contain a washing compound, is supported upon the upper portion of the frame and extends considerably beyond the front of the receiver 20. The receptacle 27 for the washing compound isprovided at its bottom with a nozzle 28 o r a series of nozzles, from which the washin g compound may be sprayed upon the iioor. If the nozzle 28 is continued from side to side of the receptacle, a single spring-controlled valve 29 is If a series of nozzles is employed, a number of valves 29 are used. In any event the valves are opened by an attached cord or chain 30, which is led out through the receptacle along the handle 31 to an engagement with a lever 32 on the said handle, as illustrated in Fig. 1. When the cord or chain 30 is drawn rearward, the valves are drawn in the same direction and the springs controlling the valves are compressed.

A cleaning-drum 33 is secured upon the shaft 13. drum is provided with a series of brushes 34 and a series of rubber strips 35, alternately arranged. As the drum is revolved the cleaning surface of the drum is adapted to engage with the concaved surface of the lip 23 of the receiver and its concaved front surface..

In operation, the valves or valve being open, the machine is pushed ahead, whereupon water will be delivered to the floor in front of the cleaningdrum,and the said drum will scrub the floor by means of its brushes and wipe the same dry through the medium of the rubber strips. The material, liquid or solid, taken up by the scrubbing or cleaning drum will be delivered through the opening 25 into the receiver 20.

The device is exceedingly simple and durable and will clean a floor as readily and as perfectly as a brush operated by hand.

Having thus described my invention, l

The peripheral surface of this claim as new'and desire to secure by Letters Patentl. A scrubbing machine, comprising a frame,wheels mounted in the frame, a rotary brush also mounted in the frame in front of the wheels and operated from one of the said wheels,a liquid-receptacle on the frame above the brush and extending forwardly beyond the same and provided with an outlet at said forwardly-extending end, means for controlling the outlet, and a receiver suspended from the rear portion of the frame and having its forward end concaved and provided with a lip to engage the floor, said concaved end being apertured and contacting with the brush, substantially as described.

2. A scrubbing machine, comprising a frame having its side bars at their forward ends inclined downwardly, a brush mounted in the lower inclined ends of the side bars, wheels also mounted in the inclined portion of the side bars, means for operating the brush from one of the said wheels, a liquid receptacle on the upper part of the frame above the brush and extending forwardly beyond the same and provided with an outlet at said forwardly-extending end, means for controlling said outlet, and a receiver in the lower part of the frame in rear of the brush, and having its forward end concave and contacting with the brush, said concave end beV ing provided with an opening and having its lower portion extended to form a lip, substantially as described.

3. A scrubbing-machine, consisting of a frame having its side bars at their forward ends inclined downwardly, a handle secured to the rear end of the frame, wheels mounted in the inclined ends of the side bars, one of said wheels being provided with internal teeth, a brush mounted in the inclined ends of the side barsv in front of the wheels and provided with alternately-arranged brushes and elastic strips, a pinion on the shaft of the brush and meshing with the teeth of the wheel, a receptacle on the frame and having its forward end projecting beyondv the brush and provided with a discharge-nozzle, a springpressed valve for controlling said nozzle, means connected with the valve for operating it from the handle, a receiver in rear of the brush and having its forward end concaved and provided with an opening therein, the said concaved end contacting with the brush and having its lower portion extended to form a lip and wheels mounted on the rear end of the receiver, substantially as herein shown and described.
