Sperry Gyrocompass Mark 14. Folks, Gyro-compass Mark XIV, Mod. 1, 17-1400D, 1944, is a service manual for the most widely built gyro of WW II. This gyro was used on pretty much any ship that did not have automated fire control. In this online version of the manual we haveattempted to keep the flavor of the original layout while taking advantageof the Web's universal accessibility. Different browsers and fonts will causethe text to move, but the text will remain roughly where it is in the originalmanual.

In addition to errors we have attempted to preserve from the originalthis text was captured by optical character recognition. This process creates errors that are compounded while encoding for the Web. Please report any typos, or particularly annoying layout issues with the for correction. Richard Pekelney Webmaster INSTRUCTIONS 17-1400 D JUNE 1944 SPERRY GYROSCOPE COMPANY, INC., MANHATTAN BRIDGE PLAZA, BROOKLYN, NEW YORK I SPERRY GYRO-COMPASS FOREWORD 1.

The purpose of this book is to enable the ship's personnel to operate and maintain their Gyro-Compass in a satisfactory and economical manner. If the basic principles of the Compass are understood and the rules laid down for operation, care and maintenance are followed carefully, the instrument should give satisfactory service for many years. Normal replacements, due to wear, will be necessary from time to time. Most of these replacements may be made by the Compass operator, following the instructions contained in this book. But the operator should not attempt to make any repairs or adjustments other than those noted in the text, otherwise he may seriously affect the adjustments and balances of the compass. It will be found more economical to have a Gyro-Compass Service Engineer make any major adjustments, overhauls, etc.

The Sperry Gyroscope Company, Inc. Maintains a staff of expert Service Engineers ready to render quick and efficient service in any port in the United States. A list of service stations will be found at the end of this foreword. Manual for 2017 hp mercury outboard. If it is necessary to engage a Service Engineer, time and money will be saved by stating in your request for service the nature and cause of the trouble. Basically the Compass is much like the very popular Mk.

VI and VIII Compasses, of which over 1000 have been placed in service on ships representing almost every maritime nation in the world. Many improvements in design are present in the new compass but since they are too numerous to detail here, only a few outstanding changes will be mentioned. The binnacle is designed to support the Compass in such a manner that the entire unit is shock-proofed. The doors are large, permitting free access for oiling and cleaning. The mercury ballistic is cast in one piece so as not to be subject to distortion. The mercury tubes are made of stainless steel.

The follow-up system for the Compass is the a-c amplifier type. The great advantage of the Amplifier Unit over the trolleys and contactors, formerly used, is that it permits much smoother and more accurate transmission of the Master Compass readings to the repeater compasses.

Its use also eliminates any rolling or sliding contact between the sensitive and phantom elements. This serves to lessen friction about the vertical axis of the sensitive element and assists in improving the accuracy of the compass. Furthermore, maintenance requirements are minimized. In order to secure constancy of balance, all parts are made to have the utmost rigidity, thus balances once made are permanent. Special attention has been devoted to ruggedness, simplicity, and accessibility of construction. This is considered specially important for the proper maintenance of a compass equipment aboard ship.

The Mark XIV Gyro-Compass Equipment consists of the following groups of units: (a) Master Compass, by which the true north reading is gyroscopically discovered and maintained. II (b) Repeater Compasses, which receive and indicate the true heading transmitted electrically from the Master Compass.

(c) Course Recorder, which also receives the true heading electrically from the Master Compass, and makes a continuous record of the heading on a moving strip of paper. (d) Control Panel, for governing the electrical operation of the system and for ascertaining the running condition by means of a suitable meter. (e) Voltage Regulator, to maintain constant the ship's supply to the motor-generator. (f) Alarm Unit, for indicating failure of the ship's supply. (g) Amplifier Panel, for controlling the follow-up system. (h) Motor-generator, which converts the ship's d-c supply to a-c for energizing the Compass equipment. Items a and b are treated in this pamphlet; likewise d, e and f are treated in another pamphlet.

The remaining items are treated separately. The separate pamphlets are designed to be bound within one cover for convenience.
