Model of Improvement

I had long heard of a model of Col. Long’s Truss in the collection of the The New Hampshire Antiquarian Society, and long had it in mind to arrange a visit as part of research in piecing together my multiple blog entries on the Colonel and his Truss. Though I did not work to do so until coming upon this curious passage in an article titled – An Hour in the Antiquarian Room in Vol XXXII No. 1 of The Granite Monthly, published in 1902.

That initial inquiry to the Antiquarian Society was spurred by some seeming confusion found in the passage, (none of the Childs brothers have or had C.B. as their initials, nor where any of them still living in 1902) and a curiosity as to if there was any possibility that the Society perhaps also had in their collection a model of a Childs truss.

As it turns out, it was a Childs (likely Horace – visit the search bar to the right for information on the man and his truss, or for greater information on the good Col. Long) who donated this Long Truss model to the society, this sometime in the 1870’s. This would stand to reason being that Horace was a cousin of the Colonel’s and his bridge building firm was counted as among the earliest of those named as agent and sanctioned to build Long Trusses, and such a model would have been a useful tool in selling bridges of this truss type.

Col. Long’s Bridge – The Model fits in its box like a hand in a glove

It was a rare thrill to examine the model, which is truly joined with well executed wood to wood joints and holds features I have not yet seen (such as the upper lateral bracing details, and the thrust blocks on the terminal ends of iron rod wind stays) on any still standing Long Truss bridge. It was also an honor and a privilege to examine this tiny construction, it being perhaps wrought by, and likely held by the hands of one or both of these storied bridge truss patent holders.

The Bridgewright Blog would like to thank the NHAS / Hopkinton Historical Society for their willingness and cooperation in providing access to this rare piece of both area and wooden bridge history.

About Will Truax

I'm a timberframer and preservation carpenter, and regularly work on Covered Bridge restoration projects. Bridgewrighting can be a tough row to hoe, for a myriad of reasons. From scheduling issues to differing opinions and philosophies on what is appropriate in methods and materials, to multiple jurisdictions still not sufficiently vetting bidders resumes - Which is to say, just because a company is on that state approved list and capable of building that seven figure overpass, this does not mean they are capable of restoring a wooden bridge... So, I have much to say about all this and more - And despite my tough row observation, I promise not to whine. View all posts by Will Truax

    I have recently discovered your blog, and have been reading voraciously since. This particular entry stunned me; what a pristine bit of tacit knowledge; a time capsule of near forgotten information. Thank you for doing what you do, and for sharing.

      Camden –

      I’m happy you found your way by and found things worthy of a look around.

      Even though I’d seen photographs and half knew what to expect, the Long model was singularly thrilling (I was somehow even privileged to return some loose pieces to their rightful place) and I’m gladdened to learn through your taking the time to comment that I was maybe able to bring some of that to the page!

      Thanks for the attaboy.
