Rotary Clothes Hoist Patents
Lance Hill Australian Patent 215772 lodged 22 March 1956
The Hills Hoist is an Australian icon, synonymous with the Australian way of
life.
The Hills Hoist is a rotary clothes line fitted with a hoist operated by a
crown and pinion winding mechanism which allows the frame to be raised and lowered.
It was developed and marketed by Lance Hill in 1945 after he returned from the
war. The idea of a rotary clothes line wasn't new - US patent 434921 of 26 August
1890 is much earlier and there were similar products in Australia. Hillís
initial patent application lapsed, but he obtained a patent in 1956 for the
winding mechanism. Hills Hoists are now sold throughout Australia, Asia, Europe
and North America. The Hills name has trade mark protection for a variety of
products.
The full specification for the patent illustrated has 4 pages and 3 figures.
