The first and ubiquitous worm drive hose clamp invented in 1921 by Commander Lumley Robinson of the British Royal Navy. Usually made from stainless steel for corrosion resistance the worm runs in series of grooves to provide even pressure around a hose connection. The name "Jubilee" became a genericized term for these adjustable clamps, though according to the company website, the origin of the name is unknown. Also wondering about the significance of "Famous in Four Reigns."
