Hi Ed,
In the wee moments before sleep...well mostly, I have been looking and all I'm finding is stuff on metal rolling. Still, if you can shape wire that you can only get in round, that's a cool thing to have!
Stay Cool!

Think the 2 flat dies would be used to flatten wire into bezel material. Ed, does the gear drive ratchet ?
Pretty cool gizmo you have there.

No Don the gears don't ratchet
perhaps a spring based finger could be assembled
and then it would ratchet ?
that would be pretty cool
and the wire wouldn't ring/curl then
I haven't messed with it much
I was going to DD & GW
but I have no rock pszzzaazzz today

Shaping Wire
Using a rolling mill with square grooves allows jewellers to shape (often into a square shape) and taper round wires. Before starting the process the wire must be annealed, pickled and cleaned and dried thoroughly. The wire is then pushed between the square grooves and the handled turned so the wire is drawn into the grooved section of the rollers. This then shapes the wire. To ensure the required shape is achieved turn the wire each time by 90 degrees.
Formed D Shape wire
Rolling mills with D shape channels allow D shape wire to be formed, and follow similar principals as shaping. The wire is fed through the D shape section rollers and once the wire has passed through check the thickness. If it is not of the required thickness repeat the process.

You might experiment a little with soft copper wire, before trying the more expensive silver stuff.
Wish you were up here in S.D. . I'd like to get hands on with that gizmo. I'm thinking there must be a way to make it ratchet, unless a jeweler only wanted short pieces of wire. Check around the gears and look for a button or lever. One set of gears would have to free wheel for it to ratchet.
I hear ya about not having any rock pszzzaazzz today. Reached the high 90's here, and the heat pump needs a refrigerant recharge. Hit 80 indoors.

Why is a ratchet important?
I've always like the click-click sound of it, but didn't know why it was there. I have some gardening clippers that ratchet, and I can see that it holds a place, then when the handle is squeezed again, a thicker branch can be cut without pulling out and starting over.

well in this particular gadget a ratcheting
would extrude the wire out straighter, I think
but I may be wrong.
Its not at all important though
the other purpose is for economy of space
if i want to extrude 25' of wire
I need to crank the handle around and around
and where it stops nobody knows
with a ratchet it just be a back & forth motion
Don I'm surprised that you never seen one ?
or that John hasn't chipped in
I must darn near have one of kind

Ed, a lot of those gadgets were very limited production. It's something that a pro jeweler might have had in his work area. When it was produced, it was probably fairly expensive for its day. Not something the average rockhound would have. Just like my own tool boxes. I used to be a sheet metal man. I have tools that the newer sheet metal guys have never seen, and wouldn't know how to use.

Thanks to Don detective work and your insight We have the original use of this gizmo figured out ! Now I understand its original purpose! The ring goes on the flat die and grooved die rotates around it! I originally thought it had something to do with rings. Good detective work Don ! What words did you use to search? |

Ed, I think that ring sizer on ebay is probably a cheap knockoff from India or China. Notice the company selling it is listed as an importer. I'd think you gets what you pays for, Mostly

Ed, that little tool is a stone setter. At least that is what it was originally designed for. I can set channel diamonds at one time with it. I do not prefer to lose sight of the stones, but it can be done.
The other thing it is used for, at least I do, is to extrude ring shanks. The rollers can roll out the metal, without changing the geometry of the settings. Most times, in my shop, I can "stretch" a ring in less then a minute and not have to charge for it. That brings in customers. They are good tools. I have worn one out so far.
Good find.

Thanks guys for figuring it out and the links
I'm going to get an out of shape ring and take a picture of the set-up
Plus I do believe this gizmo as some application for wire
maybe not mostly
