What is this tool?

The item came from a tinkerers garage. He worked on cars, rv’s, campers and electronics.  the only identifying information is red tape on the box that says made in Austria. Thanks

yes, its a change-wheel set for a lathe.

Tiny lathe..

Yes. Model engineering scale, like an EMCO (made in Austria)

Ok, now I’m going to be lazy and ask the question... what is the value on something like this? I’m trying to determine what needs to be sold, and where to try to sell it if it has value or useful life. These were important items to the man that owned and used them, I’m trying to be respectful of his memory by making sure his treasures are given a new life and not just tossed away. Thank you all again. This one had me stumped, and I’m pretty handy in the workshops!

They should belong to a model engineer.

Where are you in the world Kim ? I can perhaps suggest some sites you could post a message on.

Take some pictures of what you want to move on, this is a great place to post ordinary tools. The changewheel set is probably too specialist.

I am in the United States of embarrassment. More specifically Southern California. Thanks for your help

I am a member of a model engine group - I could post a link to the picture and see if there is any interest.

That would be interesting, if you don’t mind. I’m cutting my teeth on these items so I have a lot to learn. I’ll take any help I can get!

I know what its off now. Its probably worth $100 or so.

From one of my acquaintances

"

Looks like a quadrant and change gears for an EMCO V10P lathe. I had a
metric one and I made a quadrant and the change gears so I could cut
imperial threads.

Of course your set could be to cut metric threads on an inch machine.

Emco stuff was very expensive so it would have cost a fortune new. Even
now, I imagine it would fetch a good price in the right market.

That was so much help! Thank you for taking the time to access the help of a friend. I’m going to follow through with this information and make sure it gets in the hands of someone that can put it to use again.

Latest word is: You need to know how many teeth are on each gear - its usually stamped on them. That will tell buyers if its a metric or imperial changewheel set.

I will check that out.

Then I would consider, that many gears, as a possible means for thread cutting as in bolts, many varied screw thread counts (like 256-4 through 26-10)

Thank you guys so much! I’m glad you were here to help me. I had no idea.

Is there supposed to be a picture of the unknown artifact, attached to this topic?

Just from the description you have written for us(i.e. it came from a tinkerer's garage, and it came in a box that says 'made in Austria', and the tinkerer, owner of the garage, worked on cars, rvs, campers, and electronics), I am not sure if any but the most gifted clairvoyants among us, can tell you more about your tool.

Thank you, Kim, for attaching a picture of your artifact.

Unfortunately, this thing, whatever it is, is something I do not recognize, and I can only speculate as to what it might be.

Part of it looks a Christmas tree made of gears.

I think there is such a thing as a "cone gear", a stack of gears that all turn together, but I do not think that is what this is.

To me it looks like those 12 gears are loose, and they have all been stacked on a bolt, and maybe that was done for the sake of organizing them.

That is to say, if you had 12 gears like this, and you stacked them in order of increasing (or decreasing) size, it would be easy to count them, and it would be easy to see if one was missing from the sequence.

If they can be removed from the bolt they are stacked on, you might find some writing on the faces of these, what I am guessing are gears. They might have numbers, or sizes, printed on them.

Also I am guessing those three stubby bolts, in the long slot, on that black metal thing.... I am guessing those are just the right size to fit the center hole in any of those gears.

So, you could pick three gears at random, and then mount them on those three bolts, and...

And then what? Well, that is where I run out of ideas.

Basically, to me, this mostly just looks like gears, and maybe the black steel thing, with the long slot and the three stubby bolts, is a place to mount some of those gears temporarily.

That's just a guess. I am totally not seeing the larger context; i.e. what this thing was a part of, and what it was intended to do.

I thought I posted the picture, thanks for any help on this. A picture definitely is worth a thousand words

Not an expert on Austrian tech but it could be as simple as a gearset for a lathe.

BTW what language is that note written in ?

iceng15 days ago

An Austrian gizmo to clamp around a motor exit shaft bump and an assembly to connect two or more gears for another machine..

That bot right body shift position screw lock to engage the assembly makes me believe this could have been some kind of electrical speed matching device for a generator..

It could not be a distributor device or valve cam driver because there is no intended sync with the mired gears available...

What kind of motor driven machine needed adjustment of speed and direction to such a degree 80 years ago.. Perhaps a machine gun mount or a super charger (air_compressor) to increase horse power..
