Emmert Mfg Co... what's it called?

[swervncarz]

Anyone know what this instrument is called or what it's used for? Marked Emmert Mfg Co.

Is that a pulley on the end of it?

Perhaps part of a machine?

Emmert made things besides really desirable vises, like this sanding machine http://owwm.org/viewtopic.php?p=195846

That appears to be part of an Emmert Portable Drafting Machine. A nearly complete machine is shown here:

Scroll down to about the middle of the page.

There is one currently listed (relisted) on eBay as an Emmert Drafting Tool, less complete than yours, that isn't getting any bids at $17.99.

Thanks for the info.... You guys always have the answer!

Etch-a-Sketch, 1930's style ...neat :)

That is a very cool tool.  And the website link I also appreciated.

Looks like drafting scales/rulers would be attached to the two arms of the right angles piece - these can then be set at any angle for drawing angled lines....
