not your 'bag & motor on a broomstick' uprights
The Singer gets the prize here of ahead of its time and solved problems,such as cord coming out at upper area,that todays vacs can not match.It also could use adapter and hose but many would get the hand vac.I think there is a 1949 full page ad that includes mention of Loewy.--The One Stroke was about 1955.Not sure if I am in the '2' but I have one.Here we should wonder at both styling and naming of this vac.I think Eliot Noyes did much WH design work at a corporate level including logo but don't know who did small appls.The One Stroke continued the A frame handle and added ideas such as the handle locking when carried.--The GE was at a time of mostly canister sales.The cord storage was a pouch on bag that was similar to lawn chair material that was everywhere at that time.The hose adapter had a rubber strap that held handle in upright position for tool use.--The DAM added clean air and great tool use.With a certain new book we may understand more of the Hoover family styling of this period.DAM motor was same as Slimline/Portable and Slimline/Portable/Constellation used same bags.Yet another better Hoover idea from this time.A few later DAMs added headlight, height adjuster and tool rack at end of hose making them the ultimate until power drive.
