Odd pliers, how were they made?

[ojh]

I gathered these up years ago and cannot figure how they were made. I've never found a use for them but i think they are neat and pick them up from time to time and ponder how they were put together.
My camera isn't the best, but if you guys look closely there isn't any hinge nor screws. The jaws of one half pass thru the jaws of the other half on a hole that is smaller than either set of jaws. The is no hinge pin, nothing.
Inside the handle on one side it says 'England' and the other might say 'PS Stubs 17' it is very difficult to read it.
They are duckbill and taper to a thin bill. I have no clue what they were used for.
What do you guys think and how were they put together?

My idea is a complete shot on the dark here but it's the only thing I can come up with right now. Instead of having just three pieces where you have a handle and head on each piece plus the center, you actually have five pieces. You would then have the two handles and the two heads along with the center. You place all four into the center piece and line them up properly and press them together. (Edit: Press together the each handle to it's corresponding head) I am probably wrong, but it's the only thing I can come up with. Wish I could hold them and get a good look at them, could most likely give you a better idea then.

Maybe you could submit your question here? I know they show things that are still being produced but you could always ask on there maybe even get a response.

Box joint pliers, good stuff.
There is a center pivot/pin in there. I can see it in your crummy cell phone pictures , #3, top right.

The "outer" half was basically forged in place. The slot was opened as an "eye", the inner jaw slid through, then hammered closed.

And yes, there's a pin, it's just that it was closely pressed in place, and then ground flush. With a little rust and tarnish, the seam disappears.

Doc.

This one is going to kill some of you guys but to throw jet fuel on the fire of how those pliers were made if you ever get the chance visit the Warther Museum in Dover,Ohio.

Mr Warther would take a small block of wood and make about seven cuts with a sharp knife and what he made was a copy of those pliers that the op is presenting.

He made one of the most fantastic trees made out of one block of wood and it had thousands of pliers! His trains are so life like that it is amazing!

Heres a closer look at the 'hinge' area, i scotchbrited it to clean it. There is a slight dark spot that might be where a pin could be.

For lack of nothing much better to do i googgeled 'PS Stubs' he was a precision tool crafter back in england in the 17 or 1800's, his tool were for making watches etc and other precision work. They have some of his tools on display in meusuem but no pliers. I'm gonna check some more, interesting.
