Underwater turbine operated by ocean currents

Image Number 4 for United States Patent #4026587.

An underwater turbine operated by prevailing ocean currents in which the generator casing has a large enough interior to house the generator and still provide space for an operator to enter the casing interior to inspect the generator and the electrical connections. The casing is swingably mounted on a base that rests on the ocean floor and a propeller for rotating the generator at a proper and constant speed is rotatably mounted at the forward end of the casing while a tail or fins extend from the rear of the casing for the purpose of keeping the propeller facing in the direction of the incoming water current regardless of the slight variations in the current flow. The casing is hermetically sealed and has an entrance hatch which, when opened, permits the operator to enter the casing interior. A diving bell is used to lower the operator to the casing and novel means permits the operator in the bell to secure it to the casing at a point adjacent to the hatch, thus permitting the operator to move from the bell interior into the casing interior and vice versa.
