Franklin Wiring Terminals
Many of the wiring connections on my 1926 Franklin are made with ring terminals as shown in these images. The wire is wrapped around the end of the terminal and then the “legs” folded over like an eyelet/rivet as used in clothing, shoes, etc.



Franklin refers to them as Reference Number R-5813, Drawing Number 30×31, “Wire Terminal. Light friction type (3/16″ hole) Hand punch for attaching 30 x 31 terminals can be secured from United Shoe Machine Co., Boston, Mass.”

Several hours of searching online have failed to reveal anyone selling these in 2016 – 90 years later, but did turn up the patent applied for in 1923, granted in 1928 for the machine to put these terminals on the wire. See https://www.google.com/patents/US1677968.
