- ABSTRACT [22] Filed: July 15, 1970 A compact floor scrubbing machine is provided.
- the floor scrubbing machine is relatively small, with a short length [21] Appl 54991 I rendering the machine more easily manipulated or maneuverable than floor scrubbing machines heretofore known.
- a 52 us. c1 ..15/353, 15/320, 15/377, cleaning Solution pp y tank is mounted on a rear portion of 5 40 the machine and motors are located forwardly thereof for 511 int. Cl.
- This invention relates to a floor scrubbing machine and particularly to a floor scrubbing machine with a separable recovery tank.
- the new floor scrubbing machine has a water supply tank mounted adjacent the handle and a water recovery tank supported near the handle and located partly above motors which are used to drive the rotatable scrub brushes and an exhaust blower. Part of the recovery tank is also between the motors and the supply tank.
- the recovery tank has an opening communicating with an air inlet for the exhaust blower and another opening communicating with an air passage for a rear-mounted squeegee.
- the tank further has seals associated with the openings which automatically seal when the recovery tank is positioned on the machine.
- the recovery tank also can be removed simply by raising a hinged lid, without any fasteners or clamps for the tank being required. Further, any baffles desired to direct air in the tank can be carried by the lid.
- the floor scrubbing machine also has a unique mounting arrangement for the squeegee which can be readily manipulated by the operator's foot between a retracted position and a floor-engaging position. This arrangement also enables the pressure of the squeegee on the floor to be readily adjusted.
- Another object of the invention is to provide a floor scrubbing machine with an improved separable water recovery tank.
- a further object of the invention is to provide a floor scrubbing machine which is more easily manipulated and operated than those heretofore known.
- Still a further object of the invention is to provide a floor scrubbing machine with an improved squeegee mounting arrangement.
- FIG. 1 is a somewhat schematic view in perspective of a floor scrubbing machine embodying the invention
- FIG. 2 is an enlarged side view in elevation of the floor scrubbing machine of FIG. 1;
- FIG. 3 is a fragmentary, exploded view in perspective of a water recovery tank and associated components of the floor scrubbing machine
- FIG. 4 is an enlarged, rear view in perspective of asqueegee mounting arrangement for the floor scrubbing machine, with parts broken away;
- FIG. 5 is a somewhat schematic side view in elevation of a rear portion of the machine, showing the squeegee in the retracted position.
- a compact floor scrubbing machine is indicated at 10.
- This machine is shorter and lighter than those heretofore known and is relatively easy to manipulate on two rear wheels and a caster.
- the machine includes a supporting frame generally indicated at 12 (FIG. 2) including a rear supporting member 14 and a forward supporting member 16.
- the rear member 14 has an upper wall 18 forming a supporting platform and side walls 20 which receive an axle 22 for wheels 24 at a lower portion thereof.
- the front supporting member 16 has an upper wall 26 forming a supporting platfonn and has a flexible splash skirt 28 depending therefrom around the sides and front of the platform 26.
- a front caster 29 also is pivotally supported from the upper wall 26.
- a handle post30 (FIG. 4)- extends through the upper wall I 18 of the rear supporting member 14 and is received on the axle 22.
- a panel 32 carrying a switch 34 (FIG. 1) for a brush motor and a switch 36 or an exhaust blower motor.
- Two handles 38 extend outwardly from the panel 32 with a valve control lever 40 mounted under one of the handles 38.
- a link 42 extends downwardly from the handle 40 and connects with a lever 44 of a supply valve'46.
- the supply valve 46 is mounted below the wall 18 of the rear supporting member 14 and has a pipe extending thereabove into communication with a supply tank 48 which is supported on the member 14 and is also partly supported by the handle post 30.
- the supply tank 48 in this instance has a capacity of 3% gallons of cleaning solution.
- a supply tube 50 extends from the valve 46 downwardly below the platform 26 and to branch tubes 52 and 54 terminating above rotatable scrub brushes 56 and 58.
- the cleaning solution supplied to the brushes 56 and 58 is readily controlled by the operator through the handle 40, the link 42, and the control lever 44 which opens and closes the valve 46.
- the brushes 56 and 58 are driven through an electric motor 60 (FIGS. 2 and 3) which is mounted on a gear reduction box 62.
- the gear reduction box 62 in turn is supported on the platform 26 and has drive shafts (not shown) extending therebelow which are suitably connected to the brushes 56 and 58 in a conventional manner.
- the specific drive forthe brushes 56 and 58 does not constitute part of the instant invention.
- the cleaning solution supplied from the supply tank 48' is applied to the surface by the brushes 56 and 58 and remains behind the brushes as the machine 10 moves forwardly. Substantially all of the cleaning solution is then picked up from the surface by a rear squeegee 64.
- the construction of the squeegee, per se, is known in the art. It includes a long mounting member 66 (FIG. 4) from which a forward flexible blade 68 and a rear squeegee blade 70 depend. The member 66 and the blades 68 and 70 form a partially enclosed chamber but with the ends of the squeegee open between the blades 68 and 70 to enable air to be drawn longitudinally therethrough into a central manifold portion 71.
- nipple 72 From the manifold 71, the air is exhausted through a spout or nipple 72 which, in turn, is connected to a flexible hose 74 and to an additional nipple 76 (FIG. 3) mounted on the forward supporting member 16.
- the nipple 76 communicates with a passage 78 formed by a sheet metal member in cooperation with the supporting member 16, the passage 78 connecting the nipple 76 with an opening 80 in the platform 26 of the supporting member 16.
- the air and cleaning solution are drawn into-a recovery tank indicated at 82 and to an exhaust blower 84 driven by a motor 86 which is located to one side of the brush motor 60.
- the cleaning solution is retained in the recovery tank 82 and the air is expelled downwardly from the blower 84 and dissipates from the machine.
- the blower 84 of a known design, is supported on a front supporting member 88 with a gasket 90 therebetween, the member 88 having an upper wall 92 with an opening 94 through which the blower motor 86 extends.
- the blower 84 further has a central upper inlet opening 96 which receives the air from the recovery tank 82.
- the recovery tank 82 has a lower bottom wall 98 and an upper bottom wall 100 which are connected by a slanted wall 102.
- the tank further has side walls 104 and 106 between which extends a handle rod 108 which facilitates carrying and emptying of the tank 82.
- the bottom wall 98 has an opening 110 therein upwardly from which extends an inlet air tube 112 terminating in an upper slanted end 1 14 near the upper edges of the side walls 104 and 106 of the tank.
- the opening 110 is in alignment with the opening 80 in the platform 26 when the tank 82 is mounted on the machine.
- a gasket 116 is located around the openings 80 and 110 and provides an air-tight connection therebetween.
- the upper bottom wall 100 is located above the motors and has a lower outlet opening 118 therein, upwardly from which extends an air outlet tube 120 terminating near the upper edges of the side walls 104 and 106 and generally at the level of the upper end of the air inlet tube 112.
- the outlet opening 118 is aligned with the blower inlet opening 96, with a gasket or sealing ring 122 therebetween to provide an air-tight connection.
- the sealing rings 116 and 122 are compressed somewhat under the weight of the tank 82 when placed thereon to provide more effective seals.
- a front cover or hood 124 extends around the forward portions of the side of the machine and the front thereof to enclose the motors 60 and 86 and the blower 84, along with a front portion of the recovery tank 82.
- a lid 126 is connected to the upper front edge of the cover 124 by a piano-type hinge 128.
- the lid 126 includes a top 130 which prevents the possibility of splashing of the recovery solution in the tank 82 and has a gasket (not shown) sealing with the edges of the tank to provide an air-tight chamber in the tank.
- the lid also has side flanges 132 which extend over the side walls 104 and 106 of the tank to aid in retaining the tank 82 in position on the machine, in cooperation with the cover 124.
- a rear baffle 134 is affixed to the lid top 130 and extends downwardly in front of the upper slanted end 114 of the air inlet tube 112.
- a cylindrical baffle 136 also extends downwardly from the lid top 130 around the upper end of the air outlet tube 120 and terminates short of a planar annular baffle 138 affixed to the tube 120 toward the upper end thereof.
- the baffles 134, 136, and 138 provide a circuitous path for the air and suspended recovery solution as the air travels from the slanted end 114 of the tube 112 to the upper end of the outlet tube 120, as shown by the arrows in FIG. 2. This path assures that substantially all of the recovery solution suspended in the air will drop out and be collected in the recovery tank 82, along with the fact that the air velocity decreases substantially as it moves through the tank 82 from the tube 112 to the tube 120.
- the lid 126 is held downwardly by a pair of resilient hooks 140 pivotally connected to the side walls 20 of the rear supporting member 12 and are releasably attached to rear edge portions ofthe lid top 130.
- the configuration of the tank 82 and its position primarily between the supply tank 48 and the motors 60 and 86 provides an extremely compact design for the machine 10. Further, with the recovery tank 82 being readily removable from the machine when the lid 126 is raised, the contents of the tank 82 can be readily disposed of. Also, when the tank is replaced, there are no fittings which have to be connected and dis-connected.
- the springs are under tension and urge the forward portions of the lever arms 42 upwardly when the squeegee 64 is in the operating position, as shown in FIG. 4.
- the rear of the arms 142 are thereby urged downwardly, pivoting about the axle 22.
- the degree of tension on the springs 150, as controlled by the wing nuts 156, thereby can determine the extent of pressure of the squeegee blade on the surface.
- a latch 158 can be employed to engage one of the lever arms 142 when the squeegee is in the upper position to further assure maintenance of the squeegee in that position, if desired. The operator can then easily move the squeegee to the operating position by downward pressure on the squeegee with the springs 150 then aiding to move the squeegee downwardly as the lines between the openings 146 and the tabs 154 pass once again above the axle 22.
- a floor scrubbing machine characterized by said second motor being beside said first motor, said exhaust blower being above said second motor, and said blower air inlet means being above said blower.
- a floor scrubbing machine characterized by means forming a baffle between upper ends of said air tubes.
- a floor scrubbing machine characterized by a lid on said tank and said baffle depends from said lid.
- a floor scrubbing machine characterized by means forming a vertically extending cylindrical baffle around an upper end of one of said tubes and spaced therefrom.
- a removable tank for a floor scrubbing machine including a lower bottom wall having an air tube extending upwardly therefrom, said tube communicating with a first opening in said bottom wall, first sealing means associated with said opening, said tank having an upper bottom wall spaced to one side of and above said lower bottom wall, said upper bottom wall having a second air tube extending upwardly therefrom,
- said second air tube communicating with a second opening formed in said upper bottom wall, and second sealing means associated with said second opening.
- a tank according to claim 11 wherein said second sealing means comprises a second sealing ring located around said second opening adjacent the lower surface of said upper bottom wall.
- a removable tank according to claim 11 characterized by both of said air tubes terminating at about the same level.
- a removable tank according to claim 11 characterized further by a handle rod extending across said tank between two opposite walls thereof and below the upper edges of said tank, said handle rod also being in a vertical plane located between said two air tubes.
