Post Office Safe

I got a call today about a safe in an old post office. The building is under private ownership now and they would like to be able to use this built in safe. I haven't been over to look at it yet, but the owner sent me some pictures. It looks interesting. Anyone bumped into something like this before? I am guessing that when the bolt is retracted for the combo lock that external device rotates and and releases the door.

Re: Post Office Safe

Wow, fascinating.

That would imply that the boltwork hardware that does the actual locking is all outside and exposed to attack. And further: that the dial is outside, the lock mech inside, and then the bolt then communicates with the hardware on the outside again?!

That can't be right, surely? When you go see this, please take a shit-ton of pictures.

Re: Post Office Safe

Is this perhaps just some form of pressure bar?

That's correct. Both devices are to aid in door and bolt alignment. 'Pressure-bar' or 'Compressor'.
Bolts are retracted/extended via the dial - hence the dial pins (gives the user a little more torque).

The compressor in the middle, between the two doors (your 2nd picture) is missing its' handle.
It goes on that square peg you see on the right. In a down position. You'd pull it up to release.

Looks like you're dealing with a Chicago. Four hole-change wheels with a gravity-driven lever.
Final opening rotation will be right; solid stop about 21. Contact area should be roughly 30-35.

Good luck. And win, lose, or draw... please give us some updates! :D Fun stuff!

Re: Post Office Safe

Only a guess, but the safe may be a Chicago. Here is why I think this: dial appears to be a 70# dial, hingeblocks are concealed, can't tell from pic but safe body corners may? be rounded, Chicago used dial nose pins but I've not seen any stick out past the dial ring. Chicago also put 'chicago safe and lock co' on the nose dial (can't see that in pic). Chicago also used compressor-type handles. (AKA pressure handle/bar). Several other makers also used the compressor/pressure handle/bar. Just speculation.

lol... or is it that I have nothing better to do on a Sunday afternoon? lol

Well Hawk-Lock... that's two votes for Chicago.

EDIT: but you're right about the dial pins. They extend further than any photos I've seen.

Re: Post Office Safe

Well, that gives me a good starting point. I'll start running through my manuals and see what I can come up with. If I understand correctly all of the stuff on the outside is just manually operated from the outside to line the doors up - there is no locking mechanism on the outside of the door. All of the boltwork is standard and mounted inside the door.

I am also not sure that I am going to be the one working on this. I think that the owner left messages with three or four guys. I will touch base with her tomorrow and see what is up. If I take a whack at it and get it open, I'll be sure to throw some pics back for everyone to look at.
