<p class="MsoNormal" style="margin-bottom:12.0pt">This looks to be a circular adding machine, or "adder". See<a href="https://www.si.edu/es/spotlight/adders/circular-adders"> https://www.si.edu/es/spotlight/adders/circular-adders</a> for some other examples.
And I agree, there are all sorts of fractional equivalents, many relating to 16ths, some to 12ths and others. So the idea that it is for adding up weights of things in pounds or lengths in inches or dozens is appealing. I just haven't got that yet. Whether
it was for incoming or outgoing goods, I'm not sure. Some of the fractional equivalents look like different ways of making up the amount, such as might be used if one was dispensing goods.<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">I would think about the industries that were active in that area at that time. It seems late for fur trade, too small for grain terminal activity, but for someone who knows the history better a solution might
suggest itself.<o:p></o:p></p>
