Bought a secondhand lathe (AI hembrug from the Netherlands), a beautifull machine, and a small mill.
With it came a lot of parts, tools and equipment.
After a lot of puzzeling most of the things are clear, so i know how they are used, or what their purpose is.
But three parts are a mystery for me.
So have a look, and perhaps you know a thing or two about it.
First two pictures:
This is some sort of collet, but the three parts are not separated, so it is not possible to clamp something in it. (http://)

Can you post a pic looking along the side. If the back part is a collet, then you could just mount it in the head of the lathe and use those three slots along with some custom clamps to hold odd shapes or mimic a three jaw chuck.
Do an internet search on jewlers lathes and you'll find all kinds of stuff.

as you can see the inside is still connected with the outside, so you can not force the three parts to the inside and clamp something

i know this is some sort of a chuck, but i've got nothing that fits in it

It's a blank collet. The face should be soft, thus you can machine the face, like incremental rings which would hold by id or od. You then drill a larger thru so you can draw it up with the bar.
You can make a holding jig out of it or whatever.

YOUR REPLY #4,
i think that mates to a cam lock type mounting plate and can repelace the chuck . Don't know about the inner boring, check if any other pieces you got a a matching profile .

none of my friends knew what it was, so you are a great help
thanks

here is the text for the last three pictures (did something wrong with posting it)
i really don't know what this is
has it got something to do with a lathe or a mill???
is it a mould,,, can you poor a liquid in it to become solid?????????
the white material is like rubber or silicone
i haven't got a clue

That actually looks like a vacuum table/fixture of some kind.
Is there a tapered threaded hole on the side or bottom for an air fitting?

HMM....like that game stump the band or i can name that tune in three notes. ;D
Guess it's a mold and from the size compared to your finger looks almost like one for making castable
tooling inserts or insulators. Just a quess but Dave's reply is also in the running.
What else you got jaja?

hoi Rich,
there is about four square meters of all kind of things
a friend of mine called:"do you like to buy a lathe?"
"just bought a cnc, which still isn't working, so...."
"but this one belongs to a lady who's man died a year ago, and now she wants to get rid of it all"
so i bought all what was in the room on the second floor
hired a crane and lifted the lathe to the ground on a trailer
it is a real beauty
the mill is not so special
but there are so many cutters, measuring tools, gauges, micrometers, morseconus adapters, boring heads, drills, reamers, soft "claws" for the chuck, collets and more
(on the lathe there is a special collet device, i can send you a picture of it of you like)
so now i have to learn to work with all these things, and make all that i couldn't before
greetings jaja

jaja,
That's how i acquired a lot of stuff, especialy tooling and measuring instruments. I hope when i croak the survivors at least have the brains to find out what some of the stuff is worth and not give it away. But it won't matter then.
Post a pic of any oddity, i don't mind, and i am sure somebody will figure it out or come close.
You can keep score because as of right now it's 2 to 1 and responders are winning! ;D

Hello Dave,
you are absolutely right,,,it is a vacuum table, a small one i think
there is a hole on the side, which i did not mention before
if you blow on it the air escapes from all the holes on the surface
thanks very much, you (and others) are a great help

I kind of thought so as those screws in the center of each square would be to "shut off" each square so that depending on the positioning of the parts that will get sucked down, the vacuum will not escape out of the holes that are exposed when the part is laid down.
Should be pretty useful depending on how bad the seal is.
