Bump Halt

[Eyes_Only]

Does anybody know how Ilco's new Bump Halt cylinders work? I've looked around their site and all they have is a one page ad that says their new product resists bumping. http://www.kaba-ilco.com/key_systems/pr ... aspx?id=37

Ilco's site says it's patent pending. I poked around the published applications section of the USPTO, but I don't see it.


Master Lock responded similarly in light of mass media broadcast of lock bumping too. They even went out and bought the domain name

I'm not sure if this applicant is related to either of these companies, but I found it to be an interesting read nonetheless.

Go to

then enter 20080105017 for the search phrase.

Unfortunately, you have to install a free program AlternaTIFF to view any document images from the US Patents & Trademarks Office.

I think I've seen another company using Master's Bumpstop technology. I saw this in a pdf but I can't remember where it was from or which company it was for. (No it wasn't medeco .)

Heres a little info I found.

Assemble the Bump Haltâ„¢ by inserting top pin into the spring, then placing above the shortest bottom pins(s)in the cylinder. This combination can be used in any location, however try to avoid using the first pinhole. Best results if used on bottom pin #3 or shorter.

The bump resistant components in this kit were designed by Ilco®, patent pending by Ilco®, for use in Ilco® brass cylinders. If this kit works on any other brand cylinders, it is not known by Ilco® and has not been tested.

So the design is like the top pin for the Schlage F-Series I'm guessing? How does that help resist bumping?

If I read it right, it should add the extra pressure on the spring not letting it act the same as the other pins which would take more force on that pin to lift it by that time the others have already fell back down.

has some info

So I'm not the best there is at physics, but I just read their article in The National Locksmith and even if you add more tension, it doesn't make it bump proof does it? Isn't it like comparing tossing a ping pong ball vs. a pool ball in the air? They both go up, but the heavier object just comes down faster. If that theory transfers, it should just mean that bumping is still possible, but you'll just have to be quicker and you won't have the same success rate.

Am I on the right track or do I need to buy Physics for Dummies?

They don't claim it's bump proof. It's bump resistant. Masters bump stop padlocks have already been bumped, it's just a lot harder.

with standard bump keys, or with bump keys with a special bitting?

There was a post on it awhile back. I believe the keys were standard.

I think Barry Wells describes it on blackbag as 'advanced bumping', where the key is cut with that one single cut a few depths higher i.e. 99979.
