Compass Control-Panel

The compass control-panel provides a means for controlling the various electrical parts of the Gyro-Compass, the storage battery, motor-generator and ship’s supply current. It is very compact, neat, and of good appearance. It receives electrical power from the ship’s mains and distributes it to the motor-generator set, Master Compass and repeater.

The switch panel is made up of black ebony asbestos, mounted upon angle iron. The panel is usually mounted with its back near the bulkheads, but so hinged as to admit of access to its rear.

Motor-Generator

The Mot­or-Gen­er­a­tor sup­plied is an ef­fic­i­ent and ex­cep­tion­al­ly re­li­able piece of equip­ment. Its pur­pose is to con­vert the ship’s sup­ply cur­rent into elec­tric­i­ty of the char­ac­ter­is­tics used in spin­ning the gy­ro-wheels and op­er­a­ting the re­peat­ers.

Stor­age Bat­tery

The complete failure of the electrical plant aboard a modern ship is an event of rare occurrence. If, however, such a contingency should occur, provision has been made for it in the Gyro-Compass equipment by supplying a storage battery of sufficient capacity to operate the entire equipment for a period of two hours. The battery is so connected electrically as to keep itself in a charged condition while the compass is operating under normal conditions.
