I took a look at the patent and it is not only odd but inconsistent. It
starts out talking about four stroke cycle engines but further along the
discussion is states that the engine works on a two stroke principle.

Lacking a complete exhaust stroke means that an engine doesn't ever fully
purge its exhaust gasses and efficiency suffers unavoidably. I hasten to
add that because something is or can be described and drawn does not mean
it will actually work. Here are some excellent examples:

The Patent Office patents original ideas, having dispensed with requiring
a working model of the item. So acquiring a patent only means the idea is
original and it looks like it *might* work. Do you have a working model?

It sounds as though Walter Schmied started off with ideas from a Sterling
engine ( http://tinyurl.com/83spa ) and modified them.

Best of luck with your assigned interest.
