ABSTRACT:
A squeegee support assembly for automatic floor cleaning machines of the type having a housing, drive wheels, spaced holders for floor cleaning members mounted for powered rotation about a vertically disposed axis and a substantially crescent-shaped vacuum housing and squeegee blade carrying assembly mounted to the housing for articulated movement about a vertical axis which is located at the midpoint between a diametral line passing through the axis of the holding members. The support assembly including an arm support member pivotally mounted to the housing for pivotal movement about a vertical axis, an upper arm having one end pivotally connected to the arm support member for rotation about a horizontal axis, a lower arm having one end pivotally connected to the arm support member below the upper arm end for rotation about a horizontal axis, a connecting structure at the other ends of the arms for pivotally connecting the same to the squeegee assembly and constraining the same to vertical movement with respect to the arm support member, the arms including adjusting means for adjusting the vertical pressure forces of the squeegee assembly against the floor when the blades thereof are in contact therewith and also including means for adjusting the attitude of such blades with respect to the floor surface, and a cable-pulley assembly for vertically lifting the squeegee assembly to it's inoperative position.
