[1450] Vintage Salsbury Lock From England

[@elitespear8719]

My father Michael Salsbury designed this unique padlock in the early eighties as well as door locks, and I can see from the comment below from PastPresented, they have done some research and found out some information about Salsbury Locks, so thank you for sharing. Thank you also to LockPickingLawyer for sharing the dismantling and reassembly of the padlock! Michael Salsbury started a company called Multikey Security Services Ltd 50 years ago and it is still going strong, being run by my brother. He then set up Salsbury Locks which sadly dissolved by 1989. My father passed away a couple of years ago but would be chuffed to see one of his creations being played on KZbin!

This seems to be a version of the lock described in the following article from the trade journal "Sheet Metal Industries" (vol. 60, 1982): _"A new type of locking system has been introduced by Salsbury Locks Ltd. Salsbury Locks has designed a lock that is claimed to be easy to service and that could be easily and quickly changed to operate with a different key when necessary. The result is known as the segmented instant differ cylinder system, in which the number of combinations possible is up to 4000 million. The locks operate with a dual-bladed key, which can be split in two if required so that the lock remains secure unless attended by both keyholders. Another advantage of the cylinder is that it is made in four lengths, which enables the user to select and control which personnel have access to different parts of an organisation."_ Salsbury Locks converted from a private to a public limited company (plc) in March 1984, but were recorded as dissolved by 1989. The lock is presumably an example of the design for which a US patent was applied by Michael A. Salsbury of South Godstone, England, in 1981 and granted (# 4429555) in February 1984.

[@doncervera]

It seems from the patent that the key LPL made is quite similar to the original

Well done good sir. Have a like and major brownie points for your efforts.

[@ianhitachi]

4 billion possibility's would mean 16 tooths on each side, sounds more like a concept than a working product. but if they do make longer cilinders than this one and the frst 2 tooths of the key are identical to this one i think it is possible that its about the same product.

[@sportclay1]

I worked for the USPS for 10 years and Salsbury was the lock supplier for cluster box units for apartment buildings, town house communities, mobile home parks, etc. where a central delivery placement was required . I believe this is the same company . Salsbury Industries. They are in California. (since 1936) The lock may have come from England but I think it may be American. Perhaps this was an experiment into the pad lock business ?? The company is a major supplier of mailbox security locks and the box units and lockers for institutional and industrial use. Wafer locks seem to be the majority of their product. Perhaps an email to the company would shed some light on this unique lock.

Oooh, I bet that brass ring on the outside is a dust guard! Since the two halves aren't threaded to close tightly and are instead able to be adjusted and secured in place with a set screw, without that brass collar, the gap between the two halves could allow for dust and grime ingress, so the collar covers the seam and keeps scunge out.

[@softweir]

Good point!

[@chaos.corner]

Or splash, given the UK.

[@mfree80286]

And on a slightly different model, I assume the collar could be fashioned with a ring to accept a chain lanyard so the lock can't be lost. Shouldn't be too hard to have a different latching mechanism too that this simply threads onto through a door or panel, so it makes a proprietary but reusable "core".

[@johnwinter9399]

[@privacyvalued4134]

This is one of the best locks I've ever seen on this channel from a pure engineering perspective. Disc detainer locks are generally pretty solid modern locks, but this one is extremely well designed for how old it is. The fact it can be physically rekeyed using gear teeth makes it quite unique. The only improvement I can think of is to have the threads perfectly aligned so that the set screw is largely unnecessary.

[@azarellediaz4892]

As to that ring, it may be there to prevent the lock jamming if the top is inserted too tight. Being that the body is 100% brass if you tighten that too too much it could jam tightly requiring tools to loosen it up, the ring provides two separate surfaces that prevents that from happening.

[@GlutenEruption]

That sounds right but instead of the body jamming, I think it would actually bind up the locking mechanism it it was screwed too tightly.

Can Brass cold-weld?

That's what impressed me about this design. From a production standpoint it is quite ingenious. The circular design combined with the notched brackets means that you only need to produce a very limited number of different parts in order to cover the full spectrum of configurations, and every lock made uses the same set of parts. Logistically, it must have made the production process much simpler than with more standard lock designs. I would assume that the production facility also featured specialized brackets/vises to make assembly easier than the "free floating" assembly LPL performed here.

Thank you, LPL. This was one of the most fun videos you've done in a while (at least, from my perspective as a fan in the locksport community). I know the average random youtuber has the attention span of a ferret on angel dust, but for us in the community, we dig these longer ones.

[@josephdouglas6482]

I really enjoyed the reassembly part, seeing all the small parts is cool but then seeing how all the small parts go back together kinda helps visualize how all the small parts work together. Would love to see more of this, maybe even on locks that are flawed you could explain how you could reassemble it to make a lock more secure if it's possible.

[@thejonathandoan]

That is just beautiful. Love the design and craftsmanship of that lock!

[@TheHectic0ne]

I have never picked a lock or wanted to get into it for a hobby. But after watching your videos, the puzzle behind them is something I might look into doing. The way you explain how a lock works makes it sound so insanely simple, even though I know that picking some of the locks you do is in no way a simple task. I will spend the next week just watching your videos, thank you for the content 😊

[@pleaseandthankyou708]

It would be neat if the original intention for this design included two keys that fit together to then facilitate the unlock. The keys would be intended to be held by two authorities to ensure two person integrity(TPI).

[@plopoi]

I was about to share the same thought about this lock... I would be glad to have a confirmation about this.

[@benjurqunov]

That was my thought also. The two keys being uniquely machined so they must marry up before inserting into the keyways.

[@davekimball3610]

Did you not film the machining process? That would be great to watch. LPL going all Clickspring with brass on a lathe.

[@brianb8003]

That reassembly was really interesting. It was so much more straight forward and simple than I would have initially imagined.

[@danvercillo]

I do love the engineering on this lock. Thank you for the pick, tear-down and reassembly.

[@clonerstive]

Something BEAUTIFUL about the reassembly. Thank you 🙏

[@Deedumdee]

Interesting design, the internal parts are identical no matter the bitting of the key, which would in theory help with manufacturing.

[@russellhltn1396]

I like that you can rekey it with no additional parts.

[@mickeyfilmer5551]

I think what you may have there is a typical "apprentice piece" - ie a piece made by an apprentice fitter/turner in one of the forces or a prestigious British manufacturer mid 20th century. I was an Artificer in the Royal Navy and that is the kind of complexity of pieces apprentices had to learn.The other possibility is that it was a "lock designer apprentice piece" but not your average run of the mill lock as that would have taken many, many hours to make- and so would have been prohibitively expensive to produce for general sale -considering how easily you picked it, it's security rating would have made it un-viable to produce.

[@volvo09]

What that to prove and show their skill in manufacturing and machining a complex mechanism?

[@jakraziel]

@@volvo09 yes it was basicly a final exam for apprentices. My father who was a joiner made a complex but small chest of draws for his. It's also the same root word as masterpiece.

[@W92Baj]

@@volvo09 Yeah. Apprentices in many field would have to build what is essentially a final exam piece.

[@masheroz]

@@volvo09 literally, their masterpiece. To show they are no longer an apprentice.

[@JelMain]

@@masheroz Indeed. An apprentice learned the basics, then became a journeyman to extend his knowledge, and finally returned home with a masterpiece, demonstrating to the Masters of the Guild he was himself one of their number, bringing new insight. The system started in the second half of the 14th Century.

[@Graham9042]

One of your coolest videos in a while, I'd love to see the machining of the key in another video!

[@penfold7800]

I've got very distant, slightly vague recolections of a similar looking lock, without the shackle part, securing the safety and cover plates of an engineering milling machine, (mounted horizontally) Looking at the lock you have, the screw in shackle part looks like it's made from a different grade of brass. Also, I'd hazard a guess that that loose brass ring is supposed to be sandwiched between two rubber bush rings to keep out dirt and engineering swarf. The one I remember seeing was made out of chromed steel and had knurls around the outside to unscrew the 'lock' once the key was inserted. Whether that's what you have here or not, it's still a very nicely made rekeyable lock, probably handmade on a lathe. Someone with great traditional English engineering skills made that. You should treat it like a museum piece. Thankyou to whoever sent it to you, and Thankyou for sharing it.

[@sirskidney7998]

Nice job on the reassembly! Thanks for taking the extra time to include the full process.

[@skydragonfire93]

That reassembly was way more satisfying than I could have hoped for. I'm so glad you got sent this lock and look forward to what you've got next.

[@dandychiggins7240]

This was beautiful to watch, watching an expert do something like this with such passion 🥰 If I ever find a weird lock, imma send it to him

[@StruC]

What an exceptionally interesting, beautiful and well made lock.

[@itsallgonemad]

I’m guessing the reason for the outer brass ring is because when the upper part is screwed on, it does not line up perfectly with the shackle holes & needs to be counter rotated to do so, exposing some open threads. I think the ring is there to simply ‘cover’ the slightly open portion of the thread… as well as making a satisfying ’jingle noise’! Love watching your videos, utterly mesmerising & has turned me into an avid picker!!! 😃

[@fju1107]

Thank you for recording the reassembly procedure! Very interesting.

[@nathanaelsmith3553]

What a unique and lovely item

[@LupinoArts]

I actually do have a question about the lock: How does its locking mechanism hold up compared to conventional ones like cylinders or disc retainers? Does it have inherent advantages or disadvantages?

[@TheDustyPeaches]

It makes me wonder could the lock be disassembled without unlocking the lock, or does the shackle itself prevent it's disassembly?

[@willywill3570]

@@TheDustyPeaches the shackle keeps it together. you cant un-thread the top with the shackle locked.

[@EileenTheCr0w]

@@TheDustyPeaches There's no way to unscrew the top part for disasembly with the shackle in the way as it would get lodged in the bottom part of the lock body.

[@MikkoRantalainen]

The design of this lock is basically disk detainer lock without a plug, similar to Rosengrens 32A81S, combined with key interface that looks more like a pin tumber lock. The pick resistance of this is about the same as disk detainer lock with 8 disks and zero false gates. Seeing that those sliders were spring loaded, that should have added some extra complexity but LPL seemed to have little problem because of the springs. I think that a slight redesign that would have typical disk detainer key interface (with re-keying still possible if you detach the slider part from the circular part that interfaces with the key) combined with spring loaded action for each disk would result in pretty hard to pick lock when sliders included deep enough false gates.

[@LupinoArts]

@@MikkoRantalainen Thanks for the explanation. One side-note, thou: just because LPL had no problems with the springs, that doesn't necessarily mean that any other picker wouldn't fail miserably

[@ASBO_Rob]

My primary school in Herstmonceux (South East England) back in the 80's had one of these locks on a tool box, I remember wondering if it was 1x key or 2x keys to unlock it. Sadly that where my knowledge about this lock ends. (Nice trip down memory lane tho)

[@Lilith-Rose]

That's actually very interesting, I was pretty convinced it wasn't British because I haven't been able to find anything for a "salsbury" here in the uk, nothing related on companies house and no sold or for sale items etc. Well except a few imported leftover mailboxes from the American company that were salvaged from an air base and stuck on Facebook. But to have two instances of one of these locks showing up here is making me question that

[@highdownmartin]

So probably commercial but not an apprentice piece. From Lewes!

[@fredichon]

Could be a lock originating from Salisbury with a medieval spelling of its name on the lock. It is a city located in Wiltshire between Bristol and Portsmouth.

[@Lilith-Rose]

@@fredichon that seems far less likely since the mediaeval spelling of Salisbury is sarisberie, its never been called salsbury and neither was the salesbury in Lancashire which was spelled salesbyry. Etymologically speaking Salsbury is a derivative of Salisbury rather than the other way around. Although that derivative did make its way into use as a family name, naming your company in the uk what most would percieve as a misspelled place name is just bad business, because even if they don't see it and think it is misspelled when they recall the name of your business it will always be recalled by the "incorrect" spelling in that context

[@BroonParker]

@@Lilith-Rose wow.

[@LawpickingLocksmith]

Thanks for your patience putting it back together.

[@johnarizona3820]

Thank you LPL for another great vid and showing the reassembly. God bless!

[@ginointrieri7178]

I was happy to see the reassembly.

[@sinister_lefty]

This looks like one of those things that when you pull it apart you think "Omg, what have I done?!"

[@UncleRJ]

This lock is exceptionally interesting. You could buy a bundle of these and each of them can be unique from each other just with those notches. Not only that, the same lock is able to change the key as well. This lock deserves a spot in the top shelf.

[@Dilz6669]

The reassembly was the right move. That definitely made it much more clear how the lock worked. Much appreciated.

[@woo10gamingtv11]

Goes from lock picking to puzzle box two of my favorite videos lol. Reassembly of a lock that just falls apart and he has to guess using lock knowledge. Absolutely amazing
