Hi Ad314
I thought it sounded highly improbable too, that they used an instrument in 1972 that was manufactured back in 1880. But it must have worked in exactly the same way as the original patent. I read the patent (in most details) and it sounds like exactly the same instrument.
I got the patent number from the guest calling himself "Akshun" two posts back from this one. He mentioned some other numbers in that post too and I found pictures of them as well as some two other patents from 1977 and 1978. The only one I can't find drawings of is patent 765220.
I think it's still really amazing if it was so gentle and painless to have your ears pierced with it, as I'd expected the opposite, just because it must have been a slower procedure in general, as well as slower during the actual piercing as well.
The other patent from 1880 that "Akshun" mentioned, looked very different. It was spring operated though, but other than that, it seems like there was no really easy way of guiding the jewellery through the earlobe, after the piercing.
I hope that you will write again, if you hear something interesting from the salon that did your ears.
By the way, one place to look for drawings and text, describing the various patents, is: www.freepatentsonline.com It's a pretty slow site and it's not every time you will find what you are searching for in their database. But I didn't find the perfect patent-search engine yet
Take care
