Major Eli Janney, a Confederate veteran of the American Civil War, invented the semi-automatic knuckle coupler in 1868. It automatically locks the couplers on cars or locomotives together without a rail worker having to get between the cars, and replaced the link and pin coupler, which was a major cause of railroad worker injuries and deaths ...
Like all Janney couplers, the Tightlock is "semi-automatic". The couplers automatically lock when cars are pushed together, but workers must go between cars to hook up the air lines for the pneumatic brakes and connect cables for head-end power and other communications. To separate cars, a worker must use a lever to move the locking pin that ...
The Janney coupler, later the Master Car Builders Association (MCB) coupler, [19] now the Association of American Railroads (AAR) coupler, is also commonly known as a buckeye, knuckle, or Alliance coupler. The AAR/APTA TypeE, TypeF, and TypeH couplers are all compatible Janney couplers, but used for different rail cars (general freight, tank ...
There are many variations in the design of quick couplers. The initial divergence is between those that can pick up any of a range of buckets and attachments by clamping onto the mounting pins for the attachment (known as "pin grabbers" or "pin couplers") and those that work only with buckets and attachments designed to suit that quick coupler (known as "dedicated").
Diagram of the top view of Janney's coupler design as published in his patent application in 1873. Eli Hamilton Janney (November 12, 1831 – June 16, 1912) was the inventor of the modern knuckle coupler that replaced link and pin couplers on North American railroads.
They are used in installations where the systems require a high level of torsional flexibility and misalignment capacity. This type of coupling provides an effective damping of torsional vibrations, and high displacement capacity, which protects the drive. The design of the highly flexible elastic couplings makes assembly easier.
An automotive head unit, sometimes called the infotainment system, [1] is a vehicle audio component providing a unified hardware interface for the system, including screens, buttons and system controls for numerous integrated information and entertainment functions.
