ABSTRACT:
A squeegee assembly for use in a floor cleaning machine includes a housing which includes a forward plate and a rearward plate. The opposed ends of the forward plate and the rearward plate converge toward one another to form an interior wedge. One or more squeegee blades are disposed within the housing of the squeegee assembly adjacent to the forward and rearward plates thereof. A pair of wedge bars are provided within the housing of the squeegee assembly for releasably securing the squeegee blades thereto. The wedge bars are preferably identical, each having an outer shape which corresponds to the shape of the interior wedge defined by the forward and rearward plates. A wedge member is provided for moving the wedge bars between an engaged position, wherein the squeegee blades are frictionally engaged between the wedge bars and the forward and rearward plates, and a disengaged position, wherein the squeegee blades are not frictionally engaged between the wedge bars and the forward and rearward plates. The wedge member is formed generally in the shape of a trapezoid, having a relatively short upper surface and a relatively long lower surface which are connected together by a pair of oppositely angled side surfaces. To secure the squeegee blades to the housing, bolts are tightened which draw the wedge member upwardly toward the top plate of the housing. As this occurs, the angled side surfaces of the wedge member engage downwardly facing tapered surfaces formed on the inner ends of the wedge bars, causing the wedge bars to move outwardly apart from one another. When so moved, the wedge bars are moved toward the forward and rearward plates so as to frictionally engage the squeegee blades therebetween.
