Do they lock in open and closed positions?

In that case they could be useful to to hide a foldable table extension below the table top.
Besides folding it seems to be they retract (don’t know how to express that). So the folded part could be offset to the border of the main table.

I’m not sure I’m clear… sorry

Gene, it can’t be bi-fold as they open only one way though that was my first thought.
Gepatino, they don’t lock in either position and are rather small to be used on a table.
Still a mystery.

Gene, could they be used on something like a drop-leaf table where the leaf could be flipped all the way over to rest flat on the table surface?

I’d agree with Dallas. The term brev. dep has a lot of hits for swiss made watches, lighters and what look like a few clock faces. I was thinking that the fact that there are only two holes in each side might lean towards this being a hinge for metal plates rather than wood (where you’d expect to see three holes). Maybe it holds a back cover on a clock?

During the late 1870’s these began to be used on the doors of cuckoo clocks until manufacturing of cuckoo clocks was outsourced to China. It allows the door open fully backwards while the cuckoo projection mechanism (or CPM) is engaged on the hour.
That’s my guess anyway and I’m sticking to it, but definitely for some kind of 180º flap/door.

It looks like they were designed to accommodate a trim overhang. The gap between the hinge sides when open would be a bit over 2 times the edge overhang . Thus allowing the hinge to swing 180 degrees when the door is opened. Could be used in a wooden clock case door.

Gene, I don’t really know, but it would be ideal for a folding chess board used as a top when folded and then the top would sit opened atop the remaining box perhaps turned 90 degrees. No seam in the board and room for men underneath.

Gene, I’ve found these ones and even if they are something new, maybe the use is the same:

I’ve also found this one, but they don’t say what’s the use for it:

btw, you got me browsing hinges for some 40 minutes, I’ve never imagined there could be such a variety of this things… at least now I know not every hinge is the same.

My thought is that it may be for campaign furniture.

Look at the countersinking of the holes and it seems
an ideal surface mount hinge for a folding table top
and would allow the table to be skirted for stability,
an advantage when taking portable campaign tables
into unfamilar climates.

... might be a piece of carriage, coach, train
or ship cabin hardware…

Wow, thanks everyone for chipping in on this, it re-affirms the pleasure of having a talented community at your disposal when you need an answer. Big props to gepatino!
I’m still not sure but am inclined to go with the Swiss clock connection but hey, leave it to the Swiss to be so secretive.
I’m going to mock these up in different ways and probably use them on a box lid, they sure are sturdy enough.
Thanks again

Hello Vipond, these hinges are Italian. Have a look: http://www.sepa-hinges.com/
The ones you have are not made of brass, they are casted and coated to look like brass. They are also very brittle and sensitive for not being perfectly aligned. At the website you will see that these hinges nowadays are rounded instead of almost being square. Reason is that you use a router today instead of a chisel. They are probably of better quality today.

I am restoring a furniture from 1955 with the same hinges you have, any chance of letting me by yours?

Kind regards, Henrik in Sweden

Actually, when having a second look, yours seems to be of brass, my mistake. Mine are not and they are from 1955. If so, yours are probably of better quality than mine. Would very much like to buy them.

Bingo!
The prize goes to Henrik and what the hell, if they’re real important to your restoration and you can’t find them, you can have them if you like. Postage will probably be a bit. PM me.

Great!! That makes me very happy, I have beeing looking for them for over 6 months! I just became a menber on this forum and when I try to post a message to you the rule says that I must complete 5 posts before I can send a message. Are you vipond33 on ebay? In that case I´ll send to you from there.

After looking at so many hinges I was trying to imagine how these ones work, and I’m glad my guess was right.

Interestingly, you see how there is nothing on the external
surface and how there is a lock on the door?

Thus, the hinge is more secure than the old types
of hinges with external hinge pins and may a sort of
security hinge.

from my e-mail inbox:

Hi Gene

I have received the hinges!! They just look excellent, and are exactly of the same size as mine. The mounting holes are slightly differing in position, but that is a easy fix in the wood. Very interesting is that the text seems to be an imprint with a font that looks older than from the fifties. And there is no doubt, these in brass is of a much better quality than mine. A wild guess is that as mine are from -55 in poorer quality, the factory had changed the manufacturing process and material to save money and speed up production.

Anyway, as those you gave me are the better ones, they will serve the top lid where the stress is slightly higher.

Again many thanks and merry Christmas to you.

Henrik

I’ve never been an international Santa before but this was pretty good. Wish I could find something strange and needed for everyone! Merry Christmas to all.

well done gene

scrounging around thru things
and sharing like this
imagine all the lost connections
to the good things from our past

it is a shame sometimes

that we never get to see

Did you see the really quite extraordinary card table posted recently? I wonder if that type of hinge would be used for that application.
