WHEN THE SCOOPS ARE IN CONTACT WITH THE GROUND OR OTHER SURFACE FROM WHICH REFUSE IS TO BE REMOVED, THE HANDLE IS DEPRESSED, THEREBY URGING THE SCOOPS TO A CLOSED POSITION WHERE THEY ARE MAINTAINED BY MEANS OF THE PLUNGERS WHICH ARE THEN PERMITTED TO DESCEND SO AS TO OBSTRUCT RETRACTION OF THE SCOOPS TO THEIR OPEN POSITION. A BAG MAY BE DISPOSED AROUND THE SCOOPS DURING THESE OPERATIONS SO AS TO ENCLOSE THE REFUSE SOUGHT TO BE REMOVED, THE BAG THEREAFTER BEING DISCARDABLE OR OTHERWISE DISPOSABLE AS DESIRED.
