Unless I'm out to lunch - it is a typesetting tool for counting characters from a typewritten document. Assuming the document is typed using the Elite font - one of the standard typewriter fonts - and the "return" setting used is single space... it allowed one to read/calculate the number of characters x the number of single-space lines on a sheet, albeit line by line...

Knowing those specs allowed a traditional typesetter (I am/was one) to calculate how much space that type would take up in a larger point size (having such measurements on hand of course), or to calculate what size type would be needed to fill a set amount of space.

Modern software does that for us now without having to refer to type specimen books or knowing how to do the math...
