SPERRY Electro -Nechanieal STEERING SYSTEM BRIDGES THE GAP « NM», oY, om anf) YT LMI eS 521 | been a A Py ee 4 chess Dae Chere vy cat P . “ Musuny yf p ‘ HERE are many vessels of intermediate size which are large enough to require power steering and which are not too large to be steered manually in an emergency. It is for these vessels that the Sperry Electro-Mechanical Steering System has been designed and developed. As its name implies, this gear combines in one system a complete power steering equipment and a complete manual steering equipment. It is operated electrically. If, however, the power supply should fail or be in- terrupted for any reason, the wheelsman simply con- tinues to steer with the same wheel and in the same manner. There are no switches, couplings or levers to operate in making the change over. The only dif- ference between electrical and manual operation is @ that the wheelsman must provide the power for moving the rudder. When the electrical supply is restored, he merely continues to steer. As far as his operation of the steering system is concerned, the change has never occurred.
