Who Designed the First Security Pin?

Curious question for anyone who may know. Who first invented the first security pin and when? I know it was Yale Lock Company, however, I am curious of an exact whom?

Re: Who Designed the First Security Pin?

So, I posted the same thing over on Reddit, but figured it should be posted here as well.

So, I was digging around in the High-Security Mechanical Locks: An Encyclopedic Reference and I found this paragraph. Might help lead you in the right direction.

In some locks (e.g., American and Laperche), antipicking lower pins are also used. This idea was mooted around 1940 in a patent by Crousore (Fig. 2.22), which called for grooved upper and lower pins cooperating with a channel in the plug. An even earlier method that involved modifications to the lock cylinder was presented in a 1928 patent (US 1,739,964).

Re: Who Designed the First Security Pin?

Pretty sure the mushroom pin was the first anti-pick pin and went right back to Linus Yale Jr himself which puts it back to 1860-odd.

His list of patents is pretty goddamned impressive (and wide ranging, the man had his finger in a LOT of pies) but I don't see anti-pick pins there, maybe the design was too simple to patent?

https://en.wikipedia.org/wiki/Linus_Yale_Jr.

I'd love to hear if anyone knows any different.

Michael.

I posted there as well hoping for a better chance of snagging someone who knew, sorry for the inconvenience, but thank you for the information :hbg:

I've been coming to the same conclusion that the mushroom was the first of its breed as well. The earliest patent I can locate so far is for a mushroom.

https://www.google.com/patents/US2043205

However, in the description it states:

More in detail, my invention embodies a cylinder using mushroom, or partially cut-away drivers of the class already known in this art


Not certain if "cut-away drivers of the class" means they are just cut aways of standard pins, or if it means cut away pins such as these already exist... :axeem:

Re: Who Designed the First Security Pin?

Wow, never seen that patent, it's fascinating but as you say, hard to know if it's the absolute first. Look at the little groove in the lock body. But holy shit, 1936. So late.

I am pretty certain I have the answer!

1865 the first security pin was developed by Linus Yale Jr. in a very subtle form of perpendicular notches in the top tumblers. ( you have to read the PDF version at the top)
https://www.google.com/patents/US48475

In 1928 W. D. Hainline milled notches in the top of the plug
https://www.google.com/patents/US173996 ... UQ6AEIKDAA

And in 1932 Frank E Thompson milled the mushroom
https://www.google.com/patents/US204320 ... 0Q6AEIPTAD




I cant find anything more anywhere... I am going to assume this is correct haha

Re: Who Designed the First Security Pin?

I have some old-school Yale padlocks that have mushrooms.

That's really cool! Thanks for the investigative work!
