Tuesday was a glorious October day and I found a different silo construction for our edification. This one is made entirely of curved sheet metal plates, bolted together. To tell you the truth, I don't recall ever seeing a silo like this, but surely this one is not unique. I've looked on line, and can't seem to find any information about this kind, however, the search results are overwhelmed with links to modern metal silos, so there could be something if I search harder. Obviously, this one is not new. The barn is probably 100 years old, given that it has collapsed.
I thought the top was particularly interesting.
The silo is made of curved pieces of sheet metal with lipped edges which are bolted together. Here's a view looking up.
Now I have more questions. When I look at an enlarged photo of the connections between the plates it really looks like bolt heads. But that's a LOT of bolts. Isn't it more likely they were riveted? I need to take a picture of the underside of the connections which are in shadow in the pictures I have.
Thanks to some help from Vanilla, I have discovered that this is a Martin Steel Silo. We found pictures of them from Pennsylvania; Menominee, Michigan; Wisconsin; and Vermont. I'll have to do some more sleuthing.
It's a long way from home. I won't be going there any time soon, but maybe I'll have another chance. It actually wasn't too far from the Stone Silo.
