Excerpt: ... 427. William J. Stetson, Boston. Compensating Steering Apparatus. A small working model, like the last, imperfectly exhibiting a good principle for a good purpose. The lever or fulcrum is at the side of the rudder, and near the wheel there is an India rubber buffer, capable of being made more or less rigid or compact by screws, or by the wheel itself when hard up or hard down; thus easing the rudder and wheel from any sudden blow of the sea.
