The Repeaters

An indispensable link between producer and consumer.The RepeatersA familiar application of the repeater principle is that used in hotels and public buildings, where a number of repeater clocks are operated from one master instrument. Likewise, the repeater used upon the bridge, the bearing repeater, and the one at the after steering station, are all operated by electricity in perfect unison with the Master Gyro-Compass and show the exact reading of the Master at any instant. Repeaters are operated by a small electric motor within each case, controlled by the transmitter at the Master Gyro. In designing the repeaters particular attention has been given to the electrical circuits so as to make all connections water, spray and condensation proof. Stuffing tubes of improved design are used at all outlets and entrances.A miniature electric lamp within the repeater supplies the necessary illumination of the dial. The illumination can be brightened or dimmed by turning the switch handle on the face of the terminal box.The repeaters are supplied in three styles:1. Repeater mounted on steering stand—for use on bridge.2. Bearing repeater mounted within pelorus stand.3. Repeater mounted on bulkhead in Master’s room, or at the after steering station.Special stands or fixtures can be supplied if necessary.A metal “non-reflection” cover is supplied which can be fitted to either the bridge or the after steering repeaters. The cover has adjustable doors and a hood. Its object is to exclude all light from the top glass of the repeater except at the lubber’s line. No light will be reflected into the eyes of the helmsman. The doors can be closed until a very small sector of the repeater dial appears at the lubber’s line. Experience has proved that it is easier to watch and concentrate when only a small portion of the dial is visible. A magnifying glass can be used in conjunction with the cover so that the repeater indication can be read at a distance.Bearing Repeater with Sperry Azimuth Circle.The bridge and after steering repeaters are mounted on ad­just­able brack­ets. The position of the repeater can be changed so as to allow a full face view of the dial from almost any angle.The bearing repeater is of great aid to the navigator. The repeater is mounted within the stand and, of course, shows the exact reading of the Master Compass. In taking a bearing on a distant object or a sun azimuth it is not necessary to first set the “dumb” compass to correspond with the main com­pass. A cons­tant true ind­i­ca­tion is af­ford­ed.Installation of the bear­ing re­peat­er can be made in such a po­si­tion on the up­per bridge so that it may be used for steering from that position as well as for taking bearings. A special pelorus stand cover can be supplied with windows to allow steering with the cover on, so as to protect the repeater from spray and the weather.
