Abstract

8739. Prather, F. M. April 30, 1907, [date applied for under Section 91 of Patents &c. Act, 1907 Wave energy, utilizing.-A number of floating barges are moored, and each is connected to two weights by ropes which pass around pulleys and are attached to pressure apparatus within the barge. Fig. 2 is a sectional elevation, and Fig. 3 is a plan of the interior of a barge. The barge is closed in and a water-tight chamber 16 is formed in the bottom. A rope 20 connected to the weight 21 passes around a number of pulleys 22, 23, and is connected to a movable frame 24, which also carries a pulley-block 26. The rope 27 is connected to the block on the end of the rod 28 of the piston 29, passes around a number of pulleys in the blocks 31, 32, around the pulley 33 and the pulleys in the blocks 26, 35, 36, 37, and is finally secured to the block on the rod 38 of the piston 39. Air under pressure is admitted to the cylinders 30, 40 in front of the piston 29, 39 to keep them at the rear ends of the cylinders. The piston 39 is larger than the piston 29 so that, when the sliding frame 24 is moved due to the upward motion of the barge, the piston 39 will remain stationary, and the piston 29 will be moved against the pressure of the air. On any sudden upward movement of the barge, the inertia of the parts connected to the drum 33 will prevent it from immediately rotating, and the movement of the frame 24 will cause the piston 39 to move in its cylinder against the pressure of the air. The drum 33 is connected through two trains of gear-wheels and ratchet mechanism to the shaft 58 of an air-compressor 50 for the purpose of continuously operating the compressor in the same direction, whatever may be the direction of rotation of the drum 33. A number of such barges are moored to form the complete installation.
