The Armstead Snow Motor

Take a look at this demonstration video from 1924 (no sound). What a truly clever looking device! I wonder why we don't see this design out in the wild today?

The original patent application was filed by a Seattle resident in 1920 and can be viewed here.

I've found one rumor that Henry Ford bought up the patents and the buried the project, but I can't in any way substantiate that claim.
