摘要: A mop wringer for cotton and like mops, the wringer being a tubular member adapted to slide on the mop handle, and having a pair of rollers mounted in inclined slots at the lower end of the tubular member so that as the tubular member is moved downwardly up over the mop the rollers engage the mop to roll thereon and move along the slots so that the rollers move towards each other to squeeze the liquid from the mop.

摘要: A squeeze mop having a pair of wings pivoted to a central part of the mop body, and a one piece lever and actuating mechanism pivoted adjacent the end of the handle. The lever is integrally connected to a pair of spaced actuators straddling the handle and acting on each wing so that the initial closing movement gives a rapid closing movement, and further movement gives a closing movement with an increased mechanical advantage.
