Ingersoll Invincible Padlock Teardown

Ingersoll Invincible Padlock Teardown

The Ingersoll locks are pretty cool lever locks with a sidebar. Have not yet succeeded in picking this lock with the rubber o-ring (bushing) installed.

For more information on the key for this lock, see 10Ringo10's topic

Here is the lock with the key:

Image

And the keyway

Image

Even though the lock body looks solid, it is a laminated lock, making it very strong. You can see the laminations in the area milled for the shackle area.

Image

Now for the teardown. First, insert the key and turn it like so:

Image

On my lock, the shackle comes out at this point. As has been told to me, the shackle should not come out, so something must be missing that fits through the hole at the bottom of the shackle.

Image

Inside the shackle holes, you can see the Phillips screws. These are very large screws. You need a P3 size screwdriver.

Image

Remove the key, then the screws, and cover plate.

Image

Put the key back into the cylinder and turn it to the unlocked position.

Image

The plug can now be removed by pulling the key. As you can see, this particular lock has plenty of dirt, and will now get a thorough cleaning before reassembly. On the left side, you can see the sidebar. Near the top you can see the very fat o-ring (they call it a bushing) that is used to dampen felt feedback when picking. Rather effectively, in my opinion.

Image

The cylinder turned 90 degrees from the above picture. You can see the levers installed, two per slot. One of each pair is facing each side of the key, and all levers pivot off the same pivot bar.

Image

Turned 180 degrees so you can see the sidebar. The sidebar is very beefy. You are not likely to force this sidebar to turn!

Image

The sidebar lifted up.

Image

Inside the lock body. To the left, you can see the groove where the sidebar is located when in the locked position.

Image

Here is what the parts look like when they are clean. You can see the gates in the levers that must line up for the sidebar.

Image

Here the key is inserted, and the gates are lined up. They are not perfectly lined up, as the key is a little worn, but they line up enough to work for now.

Image

The sidebar pressed down into the gates.

Image

The cleaned cylinder with the o-ring removed. You can see the hole with a pin inserted inside that would be hidden by the o-ring. This pin must be removed for further disassembly.

Image

OK, Oldfast, time to make some gut shots. :mrgreen:

Use a drift punch to drive out the pin.

Image

Now the cam is removed and you can see the spring that acts on the sidebar.

Image

Carefully remove the spring from the plug. You can see at the bottom the spring is bent to fit into a small hole. Just pull this part straight out.

Image

Now pull out the pivot pin for the sidebar and remove the sidebar.

Image

As previously stated, it is a serious sidebar. And the pivot pin ain't exactly wimpy.

Image

The end view of the sidebar

Image

Side view of the sidebar. That post at the left side is what the wire spring presses agains to push the sidebar outwards.

Image

Now turn the lock over and lift out the pivot pin for the levers. It will slide out easily.

Image

Slide the lever through and out where the sidebar was installed. Push on the side without the spring, and expect to need to rotate the lever out so as to not damage the spring.

Image

Then I figured out it is easier to push it out through the side where the lever pivot pin is located! Learn as we go, kids! As the lever is coming out:

Image

Here are the 10 levers in order. Tip of the key on the top left side, alternating sides for the first side, then top right side so they would all fit in the same picture.

Image

You can see the gates in this picture. Notice how the distance from the end of the arm of the lever to the gate varies. That is how the lever number is determined.

Image

The empty cylinder ( lever pivot side)

Image

The empty cylinder ( sidebar side)

Image

Side view of the cylinder.

Image

Note: On reassembly, that thin wire spring that works on the sidebar is placed, then the cam needs to be spun in the same direction as the spring as the cam in installed to 'wind in' the spring. Then the pin can be installed.

Hope you were not too bored!

:D Totally far from it, Gordon. Loved every second of it (even the grubby bits :D ). Lever by lever totally gorgeous.

Any idea what the model number of this is? Ingersoll's 10 lever shrouded shackle = CS712. The open shackle = OS711. There's also a OS700 complete closed shackle. However, this model has "Impregnable" on the side which is unlike all of the above while being the same 10 lever mechanism.

I've not seen your version before, which makes it all the more cool to see.

Huge thanks for sharing this.

Re: Ingersoll Invincible Padlock Teardown

Don't exactly I recall the model, though did look it up once. It is not the newer model of Invincible, which has a solid body.

Re: Ingersoll Invincible Padlock Teardown

GoooooooooRDON!!! Absolutely fantastic breakdown.

Interesting for me to see, as I have a couple of these (thanks to Riy). No keys for either.
I've not had a go with other one of them yet, but it's great to see what I'll be dealing with.
Particularly interesting was that feedback dampening o-ring/bushing. I like it!

Maybe you can look at 10ringo10's post and identify the keyway, get a couple of blanks, and impression a key for them.

Re: Ingersoll Invincible Padlock Teardown

Maybe a winter time project :) I've been spinnin' more than pickin' or impressioning.
But really, I have very little time to devote to ANY of them this time of year :/
I'm REALLY lookin' forward to winter this year. Free time = lock time!

Until then, it's wonderful posts like these that help to
feed my addiction and keep the withdrawls at bay. lol

Thanks Gordon

Re: Ingersoll Invincible Padlock Teardown

Very nice Gordon. Always enjoy your lock stories. These help me a lot with my understanding of how some of these work and how clever some are made.
Sorry I missed this when you first posted but glad it showed up again.
Thanks.....

Re: Ingersoll Invincible Padlock Teardown

Nice writeup Gordon, thanks.

There is an old article in NDE magazine for picking a version of these locks, although it's been years since I edited it so I don't remember which issue, or which version of the padlock. If you haven't seen it you might want to read it and compare notes. See if it helps you with any hurdles with picking with the O ring.

Have an e-copy of that magazine issue. It recommends removing the o-ring to learn picking it, but it still is not easy.
