Snow Holly Works double acting internal combustion engines?

They sure didn't think small back in that time frame did they......

This one might be a bit bigger than the Snow Engine: https://www.youtube.com/watch?v=F8T1hRliDLA

Thanks for the link JC. It's every bit as great a design in model form as I thought it might be.

And Thanks to you too Reggie for the extra video.

It must have a pretty good muffler system because I can't hear it run.

Richard Pearse of NZ built an aero engine in 1903 with double acting cyclinders....

The guys at Northwest Michigan Engine and Threshers Club (Buckley, Mi) have an 1,100hp Snow that they are restoring. I do not believe it is yet operational, but they did have it turning over on compressed air last year.

Believe that this is the same type and manufacturer of the engine in the above post.

While browsing YT I came across a couple of rather interesting large stationary engines right at the end of THIS VIDEO The two big Snow Holly Works engines pretty well finish up the video from 8:40 and on.

Also a rather nice motorcycle made from two P&W cylinders with a custom crankcase starting at 2:40.

The idea of a twin opposed engine that uses the double acting cylinders to generate more like a four cylinder struck me as being pretty darn slick. In particular I love how the camshaft and rocker arms are arranged around the long cylinder assembly almost like valving on a flute, clarinet or saxophone. Brian, have I found your next project engine?
