Baguley valve gear
The Baguley valve gear is a type of steam engine valve gear invented by Ernest E. Baguley, the Chief Draughtsman of the W.G. Bagnall company of locomotive manufacturers. It was patented in 1893. It was used by Bagnall during Baguley's time there, then by his own company of Baguley Cars Ltd.
The valve gear is used to operate the inlet and outlet valves of reciprocating steam locomotives. It uses a rocking sector whose motion is driven via a link from a crankpin between the coupling and connecting rods.
required from the crank is determined from the dimensions of the expansion link.
