Baguley valve gear

Baguley valve gear

The Baguley valve gear is a type of steam engine valve gear invented by Mr E. E. Baguley the draftsman of the W.G. Bagnall company of locomotive manufacturers. It was patented in 1893.

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. The ends of this link are circular and offset from the pivots. On these circular bosses the sector is oscillated by a second link from the rod to an extension to the rear of the sector.

It is believed that there is only one locomotive remaining with this valve gear Rishra which is currently at the Leighton Buzzard Narrow Gauge Railway
