This topic is a RESPONSE to Greenfield's patents from the 1960s, 1970s & 1980s.https://www.outdoorking-forum.com.au/forum/u...FIELD_-_Theo_Reinhold_Pat.html#Post78614-----------------------------------
Gday Jack, G'day All,
As always, interesting reading Jack.
Just wanted to comment that all those patents (except for the scooter) found their way into production. The height adjust and drive mechanism are self explanatory. His ideas about a spring and ratchet tensioner took on another (and more elegant) form and works very effectively.
SD has already commented on the catcher.
The idea of having a quick disconnect cutter deck found its way onto the red Greenies. Perhaps not his best idea and it was short lived in production.
......and that scooter. Who'd have thought a three wheel scooter was patentable.
And I suspect he (and perhaps the Greenfield organisation collected a good few patents during the eighties and nineties too.
Cheers,
