"Vintage Machinery" entry for E. E. Cunningham
The Saw Set Collectors Resource
This seems to be the only saw-set patent issued on this date, and an E. E. Cunningham bandsaw set has been seen with this patent date. There's not a lot of resemblance between the Cunningham saw set and the patent drawing, but both designs do use a cam-shaped lever to bend the tooth.
