1926 Presto Vacuum Cleaner No.2 patented Dec. 14, 1926

I did a google patent search based on the Dec 14, 1926 date from the one in the other thread, and interestingly not one patent showed up. I expanded the search to 12/15/1926 and then I got it... despite it clearly saying 14. The link is below. Patent number US1610384A.

It's really interesting that it uses a reverse worm drive to move the fan. It would probably need to be well greased to avoid getting stuck, but idk. It would make the gearing extremely simple. Apparently it also has to have a one-way clutch of some kind, that may develop issues and good luck replicating that part. Then again, it's survived almost 100 years, so far, so good.

Unfortunately there's rarely a concrete historical record for obscure vacuum cleaners. I have an obscure "Cadillac" vacuum, and the only real information I've been able to gather about it was from patents and old advertisements.

You could always try googling the manufacturer's name "QUALITY HARDWARE AND MACHINE CO."

Checkrate/Likes Does anyone know where to find out information on a 1926 Presto Vacuum ? It's pre electric I do know where it was manufactured and by what company and when it was patented from the machine itself. Other than that there isn't anything else out there that I was able to find. Is it very rare, worth anything ? Also I have a few 13inch Heritage nozzels. I read something here past post about them. They seem to be rare as well and am trying to determine the value as well.
