Lever locks gutted

[mercurial]

These pics are of a Chubb Definitive Patent lock.

The serial number dates it to 1901.

It is a double sided lock, but it and another identical lock of opposite handing somehow ended up used as safe locks at a bank in Western Australia.

The photos with levers removed are not the same lock as the other photos, but the only difference is the handing. Tape measure is in inches.

That is the Willenhall CT12 from the What have you/I picked today thread. It has just three of the possible five lever types.

That is a Sargent & Greenleaf 4110 deposit lock. There are also similar locks with two keys for bank and renter. The lock is changeable to a new key. For this a screw at the back must be loosened. This might also be a lock to try after picking a 6804, but this one needs a wire pick.

good to see your safe lock picked.

Here is what it looks like in a "Butters " system lock. It was/is the fore runner of many designs, where you can tension the bolt, till the cows come home, and not feel any torque or binding on the levers.

[MartinHewitt]

It looks rather simple. How does this work? Is the patent available?

PS: This might be the patent: https://www.google.com/patents/US3060716

That is a Sargent & Greenleaf 4110 deposit lock.

The levers and post assembly in that look exactly like the ones in the 6804... wonder if they're the same or a different size. Looks like it's pretty much the same lock with a curtain and fewer levers.

From the middle of the straight edge bellow the spring to the middle of the straight edge at the bottom the 4110 levers measure 22.7mm. A lever weights 3.50g. Does that sound familiar?
