Well, I have to admit, I have been wondering more and more about these devices and I asked for information about them tonight from a fellow who has lived where I work since 1929 (hard to believe, isn't it?) and he wasn't familiar with them at all. He worked the farm and the kitchen, though - never the laundry. He said they are definitely not incubators and definitely not ovens, however. When I told him that someone suggested they put people in them for cremation, he was quite insulted and wondered "what's wrong with people to think something as awful as that?" 8`-)
The mattress steamers I have seen before look like these and they used the vents to blow scalding hot steam across the mattresses. However, I have to shamefacedly admit that the more I look at these the less they look like the ones I saw all those years back. I have one more place to go to check these out, and that is the laundry at work. Some of the folks who work there have been there 35+ years, and if anyone can give a positive ID on these, they can do it.
Sorry, Bill - I'll let you know what I can find out - it might still be right, but it might be wrong.
P.S. Here is a reference about "mattress sterilizer buildings" from a 1918 article:

People blow me away with stories like these. Keep them coming. There are so many sides - anyone who thinks they have the answer, especially someone like me, is bound to be wrong much of the time. The only way to know is to continue to learn from people who have walked the walk.
Thank you for your stories - they are difficult to read and must have been very difficult to live.
The Salmon building is very cool, it's like a trip back into the old school days of locking up the crazies to the point of confinement. Very close to a prison. Maybe worse, in some ways.
Along the bottom,the inside of the firebox and the inserts above the mantle look like soap stone, i hope someone is decent enough to save this, i am sure it is one of a kind.
I'm not absolutely sure what these are, but exciters is my best guess. I doubt they are phase convertors as a generating station will already have three phase power available. Nice pictures!
I've seen lots of blueprints and the like while inside, but I generally don't spend much time rifling through them, the interesting ones are usually gone anyhow.
I enjoy collecting artifacts like postcards and architectural drawings to places I've been to or am planning to visit, which is how I came across the old floor plan.
