A base plate assembly for a butterfly sponge mop consists of two side shell pieces, each with two outwardly extending axle members. The axle members are directly connected to the front and rear walls of the mop's center sponge member support. No additional hardware or other connection fittings are required. A single spring, which partially overlays one axle member of each side shell, provides the necessary bias to maintain the side shells in a common horizontal plane in relation to the sponge support member. The side shells in this base plate assembly can then be rotated or pivoted in the conventional manner, in order to fold the sponge member of the mop and thus squeeze moisture from it. The assembly operates effectively and efficiently, requiring less component parts and less attendant manufacturing.
