1,054,537. Extruding. BABCOCK & WILCOX CO. July 8, 1965, No. 29092/65. Heading B3P. A metal extrusion press has a billet container 10, Fig. 4 (not shown), extrusion die 12 and press ram 11 movable relatively to each other along the extrusion axis, and a discard shearing device 17, Fig. 5 (not shown), movable into the extrusion axis between the die and container, this device having a punch 18 which is moved by the container to sever the discard and then withdraw it out of the extrusion axis, Fig. 7 (not shown). The shearing device 17 is mounted to swing on an axis A and after withdrawal together with the discard, ejector rods 23 are actuated to remove the discard. The press may be controlled automatically or manually.
