According to this: https://books.google.com/books?id=IzsjAQAAMAAJ&pg=PA619&dq=p...

Reeves/Phoenix sued Linville/Keystone in 1872 over the truss patent. The writing is full of technical jargon, but does make mention of columns (Among other things.)

People like Art and Nathan are more in tune to decipher it, while it looks like cuneiform mixed with hieroglyphs to me.

Thanks, Clark!

Big Four/CCC&StL was bought by NYC in 1906 (Merged in 1930). Pending on when the line was abandoned, it could either have crosses the Penn Central or Conrail.

Unfortunately, I do not.

Art, the bridge this entry is for was built in 1928.

Cited article says they plan to use a vertical lift.

Posted October 15, 2018

It's worth noting that John and I have been searching for confirmation on the link for a while (>2yrs), to no avail, but design cues + proximity, as well as the fact the owning bridge company sold off the 1870s Pratts after replacement gives both John & I a solid basis for our hunch.

I'd misread the source that mentioned Linville & Bollmann in the same breath.

Linville was the designer/engineer for the PRR (Not the B&O) starting in 1862, and stopping in 1865 when Keystone formed.

It's very unlikely that any of the spans in question came from the PRR.

Here are two patents awarded to Linville.

This appears to be the original Linville Patent: https://patents.google.com/patent/US34183A/en?oq=USNNo.+34%2... ()

This appears to be the early/basic Linville & Piper varaint patent: https://patents.google.com/patent/US50723A/en?oq=US50%2c723

And you'd be wrong that Keystone didn't make it:

https://books.google.com/books?id=SC8jAQAAMAAJ&pg=PA33&dq=du...

And this Structuremag article says that Linville himself designed it, so I'm fairly certain that it's a further evolution of his own truss design, as Linville, like Wendell Bollman (Whom he replaced at B&O) he was fond of using his own designs over any other design:

https://www.structuremag.org/wp-content/uploads/2014/09/D-Gr...

Further supporting that idea is this historic article, which mentions Linville & Piper trusses as an option, so I think these may be smaller scale versions of the L-P truss, which I've yet to find a patent diagram for (And the article with the most info is locked behind the ASCE's paywall.

It seems like some of the spans of further variants (Such as the later (Linville-Piper Whipple) may have been reused.

Two deck spans from Steubenville were reused as a road bridge in Pittsburgh ( https://bridgehunter.com/pa/allegheny/bh83120/), and John and I have already documented several of the spans of the Illinois Central's original Dubuque bridge were relocated, though none of the Linville ones seem to exist, with most being replaced ( https://bridgehunter.com/ia/linn/coggon/; https://bridgehunter.com/ia/linn/bh60489/ ) or some being lost to flooding ( https://bridgehunter.com/wi/green/bh81901/ ).

Additionally, there was a Linville truss at Painesville, Ohio that was the basis for someone's graduating thesis at the State University of New York, but there's no reference to the line using it.

Art, can you label imgs 5 & 12 as being shots of the Linville patent truss?

Here's a ASCE scan of a plate showing the design of a Linville variant.
