Type 1 made from 1877-1886
This was actually an optional attachment for the #2 scroll saw. It replaced the scroll saw table with a square former table and the forming head. The table had circular cutouts at each corner. Type 1 machines used the round drive belt.

Here we can see how it works with out the wooden top.
Type 2, made from 1886-1936, was a dedicated former machine, and used the flat perforated belt. This is the type usually pictured in most Barnes catalogs, but the catalogs show the dedicated former with the table notched at each corner, while all known intact examples have a fully square table. This type used a totally different drive design where the velocipede action drove a vertical shaft instead of a large flywheel and a gearing system converted that motion to a horizontally-mounted flat drive belt. This was referred to as the "Improved Type."
Barnes sold a large variety of the knives, usually for $1.00 each.
