Abstract

333,418. Rhodes, C. J. Sept. 7, 1929. Seaming ; scamed joints. - A press for producing a seam of the form shown in Fig. 2 comprises an upper movable die with outer portions 2, 3 carrying projections 2<a>, 3<a>, a central independently movable portion 1, and a lower stationary die with a central movable portion 6, beneath which a member 13 is slidable longitudinally to raise or lower it by wedge action. The movable portions 1 and 6, Fig. 1, are raised while the upper die is brought down on to the work. The lower portion 6, Fig. 2, is then lowered and the seam completed by bringing down the portion 1 after slightly raising the outer members 2, 3.
