Re: When/where did worm-type hose clamps first appear?

Actually Packard used a band clamp on the senior cars that looked very similar to the micro-gear clamp. So deducting for them on Senior Packards is not the best idea. Later they went to the constant tension type with the 10-32 round head screw.

Original type clamps worked when the cars were new, but are problematic after eveything becomes pitted. Thus, sealers are required and the rubber and clamps have to be lubricated for proper function.
