A “Hills Hoist” was invented in Oz early 1960’s and is a thriving business
today (lots of other products now too) - Hills Industries. Essentially the
‘new’ bits extra to existing circular clothes lines were an ability to
rotate the structures top part in the wind for faster drying and a rack and
pinion in the centre to raise and lower it into the wind by winding a crank
handle at about waist height for an average woman. So two lengths of 2 inch
galvanised pipe with a pipe that slides down the centre, about 1 3/4 inch I
guess. A casting with a pinion inside joins the two fat pipes. The lower
fat pipe is concreted in the ground. A rack is welded to one end of the
skinny pipe and it is slid down the centre of the upper fat pipe engaging
the rack in the pinion. A four arm square umbrella frame is built on the
top of the skinny pipe and galvanised multi-strand wire threaded through
small loops welded on top of the four arms. They come in various sizes
(essentially fatter pipes and longer arms with more wires in bigger ones).
Later refinements included a handle that could be twisted round to contact
the pipe so weight of the top could not unwind it, an oiling hole to lube
the rack (and crank bearings), a drain hole just above ground level so pipes
did not fill with rain water (rust the rack and pinion) and a sawtooth
collar on both the skinny and fat pipe to stop it turning in the wind when
it was wound right down for ‘mum’ to hang clothes on it. Probably more than
you wanted to know ;-)))) Sorry about lack of Jag content but you did ask.
