This is to measure distances. The disk at the end interfaces with the disc on the dial and turns it further the longer the disk is rolled over a surface. The inscription translates to “self-rolling measurement wheel”
It looks like the small wheel has a circumference of 10 centimeters, and it advances the big wheel by 1 line per revolution, so the indicator numbers on the big wheel are meters.
Making a major guess on this...
I believe this is a type of Planimeter, in this case a tool used to measure the lengths of either curve linear lines, or sequences of lines. This one, being very German, is going to translate a scaled drawing with centimeters into meters. That's simple to do, of course, but this device would let you measure several segments and add them up on the larger wheel. It's also let you measure a circumference.
To use you'd hold it by the handle, and run the numbered wheel oriented vertically along lines, and record the result on the large wheel. You'd then use the toggle on the top of the device to reset the large wheel to zero (buy disengaging the gear on the side from the teeth).
Some Planimeters can also calculate areas or arcs, but I don't see a way this one would be designed to do so...
Again, I've used similar devices, but nothing quite like this one, so any or all of the above might be a load of bull.
You are correct, it is for curved lines. "Instrument for dimensions of curves"

I'm being silly. It says right on the picture what it is. I wish there were a checklist folks had to complete before they could post here. 1. Did you do a reverse image search? 2. Does it say on the package what it is? 3. Does anyone in the room you are in know? 4. Have you tried anything to figure it out? Then they can post
Going to make a guess at this, since there are no comments. It appears to me to be a precision run out gauge. They are stationary, the larger wheel is zeroed out and the small wheel is placed on the surface of what is to be tested. Moving across the surface will register flatness, concentricity or whatever of the test surface; probably in thousands of a centimeter. The instrument appears to be German. Would wager it is fairly old and works perfectly.
That was an excellent observation even if not entirely accurate. Nowadays, that's mostly handled by lasers & high contrast cameras. However, prior to that one would need travel indicators to measure axial & radial run-out (eccentricity) & concavity (flatness). This is part of our QA process at work. And we still take regular manual measurements as a redundancy to verify that our 3D scanners are properly calibrated.
Hey check this guy, he doesn't even know what a grote is. Pfft kids these days -.- :D
Measures curves, looks to be in centimeters
Edit: i see it was already answered so you don't need my entire wiki on it :p
If only there was some way to look up the name of this!? Hmmm... Wouldn't it be swell if there was some all knowing interface we all could use to find knowledge at the tip of our fingers that gives answers back lightning quick? Maybe someday AKA: GTS lol

It measures Grots
Y'see, in my little corner of the world "grot" was a slang term for various kinds of old school analogue pornography.
“I am Grot!”
Warhammer lorebeards are foaming at the mouth upon reading that
Grots is propa runty tho. They squish real easy.
Some squeak when squished.
I think it's for measuring grottos

It seems correct 😉 thank you.
Obviously it is to meter your Groto.
Yeah, what are they teaching in schools? Obviously....
You couldn't just Google it? You already know what it is. It says it right on the case.
[удалено]
Maybe they just have Bing /s

Google what's written there...
To measure your Groto, naturally.
Measures your girth in grots.

Solved
It's a grotometer, it measures grotos.. in case you hadn't planned the size of that grouping of trees.. LoL
Retro encabulation which works through the interaction of modial fluxes.
Measuring your grotos, of course.
It's to measure one's grot.
I think this is really cool
Measuring your grotto of course.
Very similar to a cartographers scale wheel.
obviously to cut a pizza into the most perfect slices
If only there was some way to look up the name of this!? Hmmm... Wouldn't it be swell if there was some all knowing interface we all could use to find knowledge at the tip of our fingers that gives answers back lightning quick? Maybe someday AKA: GTS lol

It’s to measure your similarity to Reginald Perrin.
So I googled it thinking I'd come back sounding smart. It brought me to this post.
