...and they were still developing it in 1935! This patent is for a sound-muffling system for the air-outlet.
I'd guess the reason this never made it into production was that a) it was too ahead of it's time, and they didn't have the technology to manufacture it on a large scale, at reasonable cost, and b) because they couldn't get it to run quietly enough to be considered acceptable by the day's standards. All that metal must have made it pretty heavy, too!
There would have been various working prototypes of this machine; who wants to bet some still survive in Hoover's Vault?
