(57) A mop wringing device having a rotary member (34) connected to a mop wringing member
(14) to move said wringing member (14) between an open position in an inoperative
state of the device and a closed position in an operative state of the device, an
operating mechanism (42,44,46,48,50) for rotation of said member (34) between said
positions comprising a first linkage (48,50) that is displaceable in a first stage
of moving the wringing member (14) from said open position, said mechanism then being
operable to move the wringing member through a second stage of movement to said closed
position while the elements (48,50) of said first linkage remain fixed relative to
each other, in each of said stages of movement the operating mechanism effecting the
movement of the wringing member with a positive mechanical advantage.
