Floor treating machine
First Claim
1. A floor treating machine, comprising:
- a frame;
a brush housing operatively connected to said frame;
a rotatable brush for treating the floor; and
means for positioning said brush with respect to the floor, said means for positioning said brush with respect to the floor further including means for regulating the contact pressure of the brush with respect to the 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. A high speed polisher is also disclosed capable of attaining rotational brush speeds of 2000 RPM and over. The polisher is controlled by an electric and pneumatic control system.

13. A machine for treating a smooth surface such as a floor, comprising:
-
a frame; a housing operatively connected to said frame; at least one brush rotatably connected to said housing; means for positioning said housing operatively connected to said housing for selectively lifting said housing away from the smooth surface and lowering said brush towards the smooth surface; a source of compressed air, disposed in said frame; and means for controlling said means for positioning said housing operatively connected to said source of compressed air to enable said means for positioning said housing to raise and lower said housing to maintain substantially constant pressure of the brush relative to the smooth surface while said brush is being operated. - View Dependent Claims (14, 15, 16)

17. A floor treating machine comprising:
-
a frame structure; a housing operatively connected to said frame structure, means for treating the floor operatively connected to said housing; means for lifting and lowering said means for treating the floor operatively connected to said housing; a source of pressurized fluid; and means for controlling said means for selectively lifting and lowering said means for treating the floor operatively connected to said source of pressurized fluid to enable said means for lifting and lowering said means for treating said floor to position said means for treating the floor substantially vertically with respect to the floor and to regulate the contact pressure of said means to treat the floor against said floor to a substantially constant level while said means to treat the floor is operating.
