Scrubber head anti-vibration mounting
First Claim
1. A surface conditioning machine comprising:
- a support structure and lower supporting wheels mounted on said support structure and defining a horizontal plane of support;
at least one powered surface engageable conditioning element beneath said support structure;
a carriage connecting said at least one conditioning element to said support structure whereby said at least one conditioning element is vertically movable beneath said support structure;
a power actuator between said support structure and said vertically movable carriage for raising or lowering said at least one conditioning element; and
a frictional motion dampener between said carriage and said support structure to dampen vibration of said carriage during operation of said at least one conditioning element.

Abstract
A floor surface conditioning machine, typically a floor scrubbing machine comprising a support structure and supporting wheels, powered scrub brushes beneath the support structure, a brush carriage connecting the scrub brushes to the support structure, and a frictional motion dampener between the brush carriage and the support structure to dampen vibration of the brush carriage caused by the scrub brushes, this frictional motion dampener having a pair of friction members spaced from each other and astraddle a fixed member, and a pair of biasing springs biasing the pair of friction members against opposite sides of the fixed member. The fixed member includes a cam track and the friction members have a cam follower therebetween to follow the cam track during vertical movement of the brush carriage.
