2 claims: 2 independent, 0 dependent

  1. 1
    I claim:1. In a pump of the class having a reciprocating piston and a piston rod secured thereto, said pump adapted to 30 be submerged in an undulating body of water, a float member on the surface of said body of water, means for anchoring said float so as to maintain it in a predetermined position relative to said pump, and means operably connecting said float member to said piston rod whereby the 35 rise and fall of said float member with the undulations on the surface of said body of water will effect a reciprocation of said piston, and means carried by said float member solely to materially supplement the normal buoyancy thereof and to minimize the possibility of its becoming awash in turbulent water.
  2. 2
    In a pump of the class having a reciprocating piston, a piston rod secured thereto and respective inlet and outlet ports, said pump adapted to be submerged in an undulating body of water, a flexible flow line connected at one end to said outlet port and at its other end to a manifold, a float member on the surface of said body of water, means for anchoring said float so as to maintain it in a predetermined position relative to said pump, and means operably connecting said float member to said piston rod whereby the rise and fall of said float member with the undulations on the surface of said body of water will effect a reciprocation of said piston, a circumferential vane carried by said float member and extending horizontally therefrom relative to its position in the water, said vane constructed solely to materially increase the normal bearing surface of said float member against which the water will act and thereby materially increase the efficiency of the pump by minimizing the possibility of its becoming awash in turbulent water.
