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."
I think they're just establishing that the clamps have been well regarded through the reigns of George, Edward, George again, and Elizabeth which would cover the time period 1921-onward. Some older Brits have the habit of describing time by reigning monarch.
ReplyDeleteThat does sound feasible, When I googled it, i came upon a Thai historical novel named Four Reigns, releases a few years before. I could not make any connection there. https://en.wikipedia.org/wiki/Four_Reigns
DeleteThank you for this. A shallow online search for Cdr. Lumley Robinson led to the Wiki page on Marman clamps, which led here:

Gosh I'd love to have a big box of those, in many popular sizes!

Marman clamps, similar but higher spec I guess, how that led to pyrotechnic bolts I don't know, but I can see a few uses for those things too!
