[1] Rotary pneumatic tools replaced the large, heavy piston type in 1928. New line followed new line as the years passed.
Gilbert Toyne's final patented rotary clothes hoist design was in 1945 "Improvements relating to hydraulic clothes hoists" (Australian Patent No. 128009) [8] Hydraulic clothes hoists used fluid as a means of raising and lowering the clothes line frame.
