Title: Innovations of James Nelson Harrington
Introduction
James Nelson Harrington is a notable inventor based in Olathe, KS (US). He has made significant contributions to the field of technology, particularly in the design of mechanisms for gyroscopes and command systems for aircraft. With a total of 2 patents, Harrington's work showcases his innovative spirit and technical expertise.
Latest Patents
Harrington's latest patents include a "Caging Mechanism for Gyroscopes" and a "Command Bar System." The caging mechanism is designed to cage the inner gimbal of a directional gyroscope to a horizontal position. It operates through the depression of an actuator rod, which turns a caging disc that moves linearly toward the inner gimbal. This mechanism utilizes a pair of pins with enlarged heads that interact with cams on the inner gimbal to achieve the caging action. Additionally, the actuator rod features an override spring that cushions the caging force, allowing for further depression of the rod to cage the outer gimbal.
The command bar system provides pitch and roll commands to an aircraft pilot. This system is supported by a magnet assembly that pivots on perpendicular edges corresponding to the pitch and roll axes. A permanent bar magnet within the assembly has its ends received in bobbins with coils wound around them. These coils generate fields that selectively deflect the magnet, enabling pitch and roll movement of the command bar.
