I also believe that it's more likely that the font was informed by what was commonly taught as good lettering for technical drawings in that era.
For example, consider the one-stroke gothic lettering in 1883's Standard Lettering, published by the Columbia School of Drafting:

And here's A TEXT-BOOK OF FREE-HAND LETTERING, part of the TECHNICAL DRAWING SERIES, first published in 1895:

Consider the "single-stroke lettering" suggested in that texbook:

Also consider the model forms for pre-penciled gothic lettering:

It seems that such lettering was already common when the machines were introduced to produce similar lettering.
