  • Floor surface cleaning machine
    Patent number: 6427285
    Abstract: A floor scrubber (10) is disclosed including a drive lug (62) for removably connecting a scrubbing member (64) to a drive (60) and having a trough for receipt and catching of solution for passage to the surface. The mount (58) for the drive (60) is biased by a spring (67) to pivot relative to a linkage plate (46) in turn pivotably mounted to the chassis (12) at an acute angle to the forward movement direction. The vacuum assembly (92) is sandwiched in a socket (100) formed in the bottom wall of a recovery tank (90) by a mount (106) to deaden the sound generated thereby and to allow air communication is inside of the socket (100) but generally preventing entry of solution therein. The squeegee assembly (152) is biased by a gas spring (150) to engage the surface at a constant force independent of the pivotal position of the squeegee mount (148).
