This Old Barn

[quicksandfarmer]

My place has been a farm since the 1680's, but the oldest buildings are from the mid-19th century. The most prominent building is the barn, which was built as a dairy barn. According to the tax records it was built in 1850. When I bought the property the barn was in pretty bad shape, I was worried that a big winter snowstorm would bring it down. Since then I've done a number of things to preserve and restore it, although I still have a ways to go.

The barn is what's called a "suspension barn." I haven't been able to find out much about suspension barns other than they are rare. This website: Suspension Barn shows the construction of a suspension barn similar to mine, although there are some differences. My barn has three levels: a basement that is about 10' deep, a main floor, and a hay loft (or "hay mow" as they call it around here, rhymes with cow.) The reason it's called a suspension barn is that the main floor and the loft are suspended from the framing by wrought iron poles. In the original design the basement was completely open.

Like all old buildings around here it was built facing the sun, with the ridge going east-west. The basement floor is at the original grade with a wide door in the western wall. The stone foundation was built above ground, and then dirt was brought in to fill in the north and south sides up to the level of the main floor. There are big sliding doors on the north and south walls, and they used to drive wagons up the dirt ramp and through the barn. In the summer the lofts would be filled with hay this way.

The east side of the barn contained nine stalls for milking cows. The west side had two box stalls for horses. In the center of the floor is a trap door leading to the basement. Hay would be forked from the loft down to the cows and horses, and the stalls would be shoveled out into the trap door. A wagon would be parked in the basement below the trap door, and the manure would be taken out to the fields.

The construction is post and beam with wooden pegs. The lumber is sawn, and from the saw marks it was sawn by a pit saw, not a circular saw. According to the local historical society the circular saw had become common by the time of the Civil War, and prior to 1800 timbers were more likely to have been worked by hand. So mid-19th century is probably an accurate date. It's sheathed with pine planks that are about 24" wide. The siding is cedar shingles.

What a beauty!

The floors are supported by post and beam structures called bents. Each bent consists of two 16' posts that rest on the sills and run the height of the wall, and three beams that run the width of the building. The wrought iron suspension rods run from the bottom beam to the top beam. The top beam carries the weight of all of the floors, and transmits it to the posts. The middle beam, which holds the loft, is supported by posts resting on the bottom beam.

The most pressing issue was that three of the four suspension rods had rusted through and failed. On the west side of the barn one suspension rod was still holding, but the bottom beam had sagged significanly where the other one had failed. The east side was even worse. Both rods had failed, and the beam was rotted out between the rods and largely missing. Previous owners had put a forest of 4x4 posts in the basement to hold up the floor, but it was precarious. The east side had held the cow stalls and I think all those years of manure had taken a toll on the framing.

It didn't help that a previous owner had driven a tractor onto the floor and collapsed the manure shoot. A neighbor told me that the only thing that kept him from falling into the basement was that he had a mower on the tractor at the time. In typical thrifty New England style he nailed a piece of plywood over the hole and driven the tractor back in again.

Repairing the east beam was the first priority. In order to do anything I had to get the weight of the loft off of it. I ran three chains with turnbuckles from the top beam to the middle beam, and by tightening the turnbuckles I shifted the weight of the loft to the upper beam:



In this picture you can see the two suspension rods outside the outer chains.

At some point, I think around 1950, when the floor of the cow stalls started to fail, the owner had poured 2" of concrete to try and stabilize it. I know this was done after the beam failed by the shape of the concrete. To repair the beam I had to take up all that concrete, which made for long sessions with the sledgehammer. On summer evenings, after the kids had gone to bed I'd go out and turn on the baseball game on the radio and spend a few hours swinging the hammer.

Under the concrete the floor was completely rotten, as the concrete came up I was worried I would fall through into the basement, and I worked on sheets of plywood. Once the concrete was out I took out the original flooring, 2x12 rough-sawn planks, and the joists, which were 3x7's on 22 inch centers.

With the floor gone, I could start removing the forest of posts supporting the beams, put a jack post under each side, then cut away the rotten parts:


Then the work of reconstruction began. On each side I put a jack post, then ran a 2x8 across and started jacking up to get the two sides level and aligned with each other:

The beam with the missing piece is 6 inches wide and 7 inches deep. A modern 2x8 is 7 1/4 by 1 1/2, so four of them make up the same dimensions, if you trim a quarter inch off of the width. So I replaced the missing section with four pieces of 2x8, trimmed. There is a local sawmill that would cut me a beam, but it was much easier to build it up in sections. Under the joints I put a 6x6 post. Since the suspension rods had failed there was going to have to be some sort of support from below, although I am trying to keep as much of the original design as possible. For the posts I had to dig concrete footings in the barn floor and set post anchors into them.

I also put another 2x8 on the outside of each side, overlapping the joint by a couple of feet. I nailed it all together as I went, and then put a few long bolts through the whole thing. The 2x8 serves two purposes. It strengthens the joint, but it also thickens the beam. There is another beam near each rod that runs perpendicular to the other floor beam, together they hold up the center of the barn floor, you can see it in the pictures above. The end of this beam rotted out where it met the main beam. I cut an inch and a half off of the face and got to solid wood. With the addition of the 2x8 it met the beam again. I attached it with a modern beam hanger.

Here's a picture of the repaired beam with posts:

Nice work!

I am about 100 miles East of you, and grew up in a 3/4 Cape house built in 1730.
Still own, and use it,..... though only Summers now.
House is in great condition for it's 289 year age.
Of course, much work has also been done over those years, and there is always more needed.

Had a new red cedar shingle roof, done this Summer.
Big $$$$ !

Thanks for sharing. Do you know what wood was used for the original post and beams?

Very Nice Barn quicksandfarmer!

Thanks for showing it! Looking forward to more pictures and description of your restoration work!

If this was mine, I would add joist hangers under those beams to ensure that they did not split in the future.

Really nice barn!!!!
