Israel I. Ziperstein and his associates concentrated on devices to stabilize, propel and elevate so-called heavier-than-air machines.
The patent drawing seen here illustrates Zipersteinís Aeronautical Device for which a patent was issued on August 12, 1924.
Through a complicated arraignment of sprockets, chains and gearing, the device above not only powered four propellers, but also
four sets of three covered wheel assemblies on a common axle that appear to have been the stabilizers.
The rest of the patent drawings can be seen including a motorized version and links to other patents that include a resilient wheel
It'll never fly.
In early aviation naturally there were more of the "wrong" brothers that the Wrights
I think the training wheels made it too heavy!
Looks like a jet fighter built by a committee.
valid idea, scale is just a little off. haha
Red Green built one of those with some old bicycles, some parts stolen off the Possum van, and lots of duct tape!
Here is the motorized version - A Model "T" engine might have worked just fine.
Well I don't know why it wouldn't fly (top pic), after all, he did put lightening holes in those sprockets. grin...
The funny thing here is that by 1924 basic aircraft design was fairly well understood, and stable flight was commonplace. One has to wonder, then, what "problem" Mr. Zipperstein was attempting to solve?
