A downward pressure mop wringer comprising:
- a. an open-topped hopper sized to receive a mop-head to be wrung and having apertures therein to permit exit of wrung out water;
- b. a pressure plate mounted in said hopper for limited rotation about a first horizontal axis located towards the bottom of, and within, said hopper, said pressure plate being approximately vertically disposed in the normal state of the mop wringer;
- c. a first crank-arm mounted for limited rotation about a second horizontal axis located towards the top of said hopper;
- d. a link arm pivotably connecting said crank-arm to said pressure plate;
- e. first means for causing rotation of said crank-arm so as to cause said pressure plate to rotate from its normal approximately vertical position to a position wherein it will exert downward pressure on a mop-head located in said hopper;
- and
- f. second means for causing rotation of said crank-arm so as to cause said pressure plate to rotate back to its normal position upon release of said first means.
