ABSTRACT:
An improved support (48) for mounting a crescent shaped squeegee assembly (46) on the body (18) of a self propelled walk behind floor scrubbing machine (10) of the type which deposits cleaning fluid on a hard surfaced floor, scrubs the floor, and then squeegees and vacuums the dirty cleaning fluid from the floor. The squeegee supporting means (48) includes first and second intermediate members (84, 98) and first, second, and third pivot means (68, 70, 72). The first pivot means (68) secures the first intermediate member (84) to the body (18) for swinging movement about a generally vertically extending axis (Z). The second pivot means (70) secures a forward portion of a downwardly and rearwardly extending arm (90) to the first intermediate member for swinging movement about a generally transversely extending axis (Y). The second intermediate member is secured to a rear portion of the arm, the securing means including an attitude adjusting member (102). The third pivot means (72) secures the squeegee assembly (46) to the second intermediate member (98) for rocking motion about a generally fore-and-aft extending axis (X), which axis is disposed well below the second pivot forming means (70). A lift cable (138) and a down pressure exerting means (124) are also associated with the improved support.
