early shape cutting
            machine patents

U.S. Patent No. 1,324,005 was issued to Mr. Worthy C. Bucknam
on December 2, 1919.
      Mr. Bucknam, who had previous patents going back to 1916
designed this as a cutting machine for trimming the flanges on
boilers.  It uses a pivoting column that supports a track extend-
ing outward from the column.  A carriage, mounted on the track,
rolls in and out as a roller follows the profile of the flange.
      The two actions, the pivoting of the column, and the rolling
of the carriage, provide full freedom of movement for the horiz-
ontal torch head, which can be seen above as part no. 40.
