Floor treating machine
First Claim
1. A floor treating machine for treating a floor having a frame structure, a brush housing operatively connected to said frame structure and rotatable floor treating brush means, said floor treating machine comprising:
- a brush lifting means for selectively lifting the brush housing away from and lowering the brush housing towards said floor, anda control means for operating said floor treating machine in a first mode wherein said brush means is rotated at a relatively high rotational speed and said brush lifting means automatically maintains said brush housing at a first position relative to said floor and a second mode wherein said brush means is rotated at a relatively slower rotational speed and said brush lifting means being infinitely variable to vary the position and the pressure of said brush housing relative to said floor.

Abstract
A floor treating machine adapted to operate as a floor scrubber and a floor polisher or buffer includes a main housing or support frame structure from which extends a brush housing assembly. The main housing contains a combined solution and recovery tank, a motive device to power the floor treating machine, a propulsion system to propel the floor treating machine along the floor, a pneumatic power system, a squeegee subassembly and electrical and pneumatic control systems therefor. The brush housing assembly is operatively connected to the main housing by a brush lifting mechanism such that two brushes selectively rotating in opposite directions in the brush housing assembly can be lifted away from the floor or moved toward the floor so that the brushes exert the correct amount of pressure against the floor depending on the job being done. The electrical and pneumatic control systems enable the floor treating machine to be selectively operated as a floor scrubber wherein the brushes in the brush housing assembly rotate at a relatively slow rotational speed and wherein the amount of pressure that the brushes exert against the floor is adjustable. The control systems also enable the floor treating machine to be selectively operated as a floor buffer or polisher wherein the brushes are rotated at a relatively high rotational speed and the brushes exert a relatively constant force or pressure against the floor.

7. A floor treating machine for treating a floor having a main housing and a brush housing, said brush housing including motor means to rotate floor treating brush means, said floor treating machine comprising:
-
a source of pressurized fluid disposed in said main housing, a brush positioning means for positioning said brush housing relative to said floor, and control means for operating said floor treating machine in a first operative mode wherein motor means rotates said brush means at a first rotational speed and wherein said source of pressurized fluid enables said brush positioning means to automatically position said brush housing at a first preselected position relative to said floor and in a second operative mode wherein said motor means rotates said brush means at a second rotational speed and wherein said source of pressurized fluid enables said brush positioning means to position said brush housing at variable positions relative to said floor. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A floor treating apparatus for treating a floor surface having a main frame structure, a brush housing assembly operatively connected to said main frame structure, said brush housing assembly having rotatable floor treating brush means, said floor treating apparatus comprising:
-
a brush lifting means manually operable for selectively lifting the brush housing assembly relative to said floor surface in a second mode of operation and automatically operable to a preselected position in a first mode of operation, a propulsion system including wheel means engaging said floor to move said floor treating apparatus along said floor surface, and control means for supplying said electrical potential to said propulsion system to move said floor treating apparatus along said floor surface at variable speeds and for operating said floor treating apparatus in a first mode of operation wherein said floor treating apparatus is used as a floor buffer and a second mode of operation where said floor treating apparatus is used as a floor scrubber. - View Dependent Claims (18, 19)
