What's This Tool For??

[64s 83]

I got this tool with a bunch of other stuff and don't know what it's for. Does anyone know it's name and use?

The best guess I have is that it gives you equi-distant points along a line. Given the diversity on this site, I figure someone knows. Thanks!!!!!!!

It is a little different from the ones I've seen before, but aircraft builders and mechanics use a similar device to layout rivet patterns.

Neat, You could say it is a stone age CNC device. it is used to devide any area into any number of segments within the limits of the tool. It is used in sheet metal layout to make multipal breaks in the metal that are evenly spaced for curved sections. I can't remember the name of it but I remember my uncle using one.

It's official name is

proportional compass

and as stated it will divide up a given area into equal sections - from 2 up to the number of points on the compass tool.
