The President Steam engine and its lattice beam
In my threads of history talk on the William West, ‘The Last Great Cornish Engineer’ I gave a passing mention to an example of a lattice work beam in the USA. Now that the preparation for that talk is over, I have the chance to follow that thread of history, a thread that leads to events many miles away across the Atlantic.
The open lattice work beam was a design used on by William West on all his most important engines, but it was a design rarely copied by other engineers. The only two non William West lattice beams I know of is the massive Cruquius engine in the Netherlands the ‘President’ engine at Pennsylvania. Both engines are examples of the massive size that the Cornish Engine principle reached towards the end of its development, and both engine have indirect links with William West.
The Cruquius was the largest steam engine in the world, and the President was the largest beam engine in the USA. The latter engine had family connections with William West, so it is the history of that engine that I hope to explore in a bit more depth in this blog.
I will dig into two rich sources of material as I explore; the research of Damian Nance, and Mark Connar. I am not yet sure where this wander across the Atlantic will take this blog, but I am sure there will be some fascinating stories to uncover. So feel free to follow this blog, and enjoy the journey
