Merkel's invention "consists in a paddle-wheel which is so constructed that the paddles will be projected beyond the circumference of a rotating cylinder as the buckets successively descend into the water, and are then drawn within said cylinder as they rise out of the water, thus preventing the lifting of the water, and a consequent loss of power..."
