ABSTRACT:
A skimmer for removing debris off the surface of a river includes a float line installed across the river at an angle with respect to the river current, and a collecting net installed at the downstream end of the float line. The ends of the line are slidable upwards, along inclined supports, to unsnag the line when a heavy object hooks onto the line. A second mechanism, assisting in raising the line, is a series of rods which swivel in a pole-vaulted fashion from their leverage at the bottom of the river to lift the line out of the water and allow the heavy object to pass underneath. If the object hits the line with an excessive force, the line will reliably break at a desired weak point. The rods may have elbow joints that would provide better leverage in shallow water.
