Chrysler should manufacture these vehicles!!

An awesome invention from the 20's that didn't catch on.

Hah! I was waiting for a title slide: "Easily Moves Over Obstacles,
Including Horses Sunken in the Snow" followed by film footage.

Different.

 

Hmmm. Yea, beat that horse one more time for me. I guess this one got
past the SPCA.

Did you count how many fences he trashed by running over them?

Another version (with modern audio)



There's some color pictures of it near the end of this page:

I guess it never caught on when compared to tracked vehicles for
off-road winter conditions. Those big screws would probably do some
dammage to exposed road surfaces, as well as make one hell of a racket.
Pretty dangerous too unless they were covered. I'm impressed the drive
chains didn't slip off.

Would have been interesting to see it in action on water.

Also would have been interesting if they made field artillery or other
military vehicles based on this design for use during WW2.

Ah - see here:

---------------
During the Vietnam War, the American Waterways Experiment Station (WES)
tested the Marsh Screw Amphibian, designed by the Chrysler Corporation.
The counter rotating screws "...propelled the vehicle through water and
marsh terrain adequately, but failed miserably on soil surfaces,
especially sand. The average maximum speed attained on test lanes was a
meagre 1.6 miles per hour."[12] Despite such disappointing results,
Chrysler produced a much larger vehicle, the Riverine Utility Craft
(RUC) for the Navy in 1969. The RUC travelled on two aluminium rotors,
39 inches in diameter. The RUC achieved impressive speeds of 15.7 knots
on water and nearly 25 knots on marsh. Again, however, speeds on firm
soils proved disappointing, reaching only 3.6 knots and crossing dykes
proved difficult - the vehicle would get stuck.[13]
