United States Patent O 3,196,474 ELECTRIC FLGOR WASHERS Brendan Gallagher, 76 Grove St., New Canaan, Conn. Filed .lune 13, 1963, Ser. No. 287,690 8 Claims. (Cl. 1S-99) The present invention relates to iloor washing machines and in particular to mvachines having a revolving :belt rotating over a pair of spaced rollers.
In .the past many devices have been provided for washing or scrubbing floors. Some have utilized rollers and tanks or spraying or other means for providing the cleaning tluid.
p Providing a clean belt or clean fluid has been a problem of the past since belts of the past have usually recirculated through the fluids they wiped up.
Fluid application of the past has not been uniform. Fluid applied to belts was either recirculated, getting progressively dirtier or sprayed onto a floor in the cleaning area or dipped ont-o a belt which recirculated either the clean fluid picked up by the machine or recirculated dirty duid of some form.
According tothe present invention, a simple continuous roller floor cleaning machine is provided which utilizes the same belt for applying the cleaning fluids and detergents which effectively segregates the clean fluid from the dir-ty fluid.
The electric oor washer ope-rates as follows. Hot water (or other cleaning lluids) is fed by gravity through a manually operated valve into a dispenser at the front of the machine which splashes the water evenly over the breadth of a continuous belt. Underneath the top spongy surface layer of the belt is a tirm base of rubber which is uniformly perforated over its entire surface. The belt moves around two big rollers and between two small squeezer rollers.
The water is Iabsorbed by the dry spongy layer of the belt yand as the belt rotates it brings the wet spongy surface in contact with the oor. The water and dirt form a dirty liquid solution which is carried by the sponge surface up over the big rear rolle-r and down to the small squeezer rollers. Here the sponge layer is greatly compressed and the dir-ty liquid solution accumulates befo-re the squeezer rollers .and the solution pours through the perforations in the trm rubber base of the belt and descends into a sump. From here it is pumped up to a container on top which can be manually removed for emptying the dirty solution. Power is obtained from an electric motor. A spur gear on the output shaft of the motor meshes with a similar spur gear which is on the end of the top squeezer roller shaft. This spur gear in turn meshes with an identical spur vgear on the end of the bottom squeezer roller shaft. The two squeezer rollers impart motion to the belt. The two big rollers are free to rotate in their bearings.
The person operating the machine would have to restrain it manually to get a sliding instead of a rolling action in order to get a good cleaning effect.
Although such novel feature or features believed to be characteristic of the invention yare pointed out in the claims, the invention and the manner in which it may be carried out, may be further 4understood by reference to the ldescription following and the accompanying draw- 1n s.
gFIGURE 1 shows a side elevation of the essential details of the electric oor washer. Parts of the three spur gears `are shown cut away for clarity. The electric motor is represented by the triangular shape in the center of the drawing. On the right of the motor is a square which represents the pump which is operated by a cam on the output shaft of the motor.

FIGURE 2 shows a front elevation of the essential details of the cleaning lluid dispenser.
FIGURE 3 shows a section of the cleaning fluid dispenser at lines 3 3 of FIG. 2.
FIGURE 4 shows an alternate form for the cleaning fluid dispenser.
FIGURE 5 is a section of the large rear roller which shows the essential details of the roller and the continuous belt at lines 5--5 of FIG. 1.
FIGURE 6 is a transverse View partly in section showin-g a spring mounting for the 'bottom squeezer roller in another embodiment of the present invention, at lines 6 6 of FIG. 1.
Referring now to the figures in greater detail, where like reference numbers denote like parts in the various figures- The container for the cleaning fluid (No. 1, FIG. 1) has baffles to prevent waves. The gently sloping bottom of the container leads to the outlet which is connected by tubing lto a manually controlled valve (marked V in FIG. 1). yThe valve could have a cable control which would be operated lat the handle of the machine. The outlet end of the valve i-s connected to the dispenser which is fully described later.
The water leaving the dispenser is distributed evenlyv over the breadth of the spongy surface of the continuous belt (No. 3, FIG. 1)
IThe belt moves around two large rollers (Nos. 4 and 5, FIG. 1) and between two small squeezer rollers (Nos. 6 and 7, FIG. l). The'squeezer rollers are the same length las the breadth of the spongy surface of the belt.
Outside the breadth of the belt and on the end of each, roller are two identical spur gears which are in mesh.v
(For clarity all spur gears are shown partly cut away.) The electric motor which provides the .power for the machine is shown with `a triangular shape and is situated approximately in the center of the machine. At the end of .the output shaft (No. 8, FIG. 1) of the motor is ya spur gear which meshes with the spur gear at the end of the top squeezer roller. @n the output shaft of the motor there is also a cam (No. 9, FIG. 1) which is in Contact with a roller follower which operates a pump (No. 10, FIG. 1).
. The squeezer rollers driven by the motor -pull the continuous belt `and cause it to rotate around the two large rollers which are free to turn in their bearings. The wet spongy surface of the belt is dragged across the door to be cleaned (the operator ,must hold the machine to prevent pure rolling) and the fluid .and the dirt form a di-rty solution which is carried up on the continuous belt over the large rear roller (No. 5, FIG. 1) and towards the 4two squeezer rollers. As the belt passes through the squeezer rollers, the spongy surface is greatly compressed and the dirty fluid builds up and flows through the spongy layer and through the numerous perforated holes in the iirm rubber base lof the belt. The iluid falls through another -perforated surface (No. 1l, FIG. 1) and .descends into a sump (No. 12, FIG. 1) from where it is sucked by the intake of `the pump and pumped up to the container (No. 13, FIG. 1) for the dirty fluid. 'Ibis container can be removed by the operator for emptying.
One form of dispenser 2 is shown in FIGURES 1, 2 and 3. The water having passed through the llow control valve (V, FIG. l) falls into the dispenser where it spreads out along the length of the dispenser behind a retainer which is sho-wn with a triangular section. When the water rises behind the retainer, it can ilow through the cylindrical holes in the retainer and then fall down land pass through the nipples which protrude from the bottom of the dispenser. The water then drops on the spongy surface of the continuous belt. For increased flows of Water, the level will buildup behind thel dispenser 'and the water will flow over the top of the retainer. Various features in the dispenser are designed to effect a fairly nniformdischarge of-water'oventhe length ofthe dispenser even when the 'iioor is 'not quite horizontal.' l
