(6.) In piercing-machinery for making seamless tubes or hollow bodies, a die for receiving and holding the metal to be pierced, having within it a support for supporting longitudinally the outer or back end of the billet, comprising an outer tube adapted to support the outer part of the billet, and an inner ram within the outer tubular part for supporting the centre portion of the metal, and supported longitudinally hydraulically by liquid held within the outer tube, and released and allowed to move away from the billet by releasing said liquid, substantially as set forth, for the purposes specified. (7.) In piercing-machinery for making seamless tubes or hollow bodies, the die 1, tube or cylinder 31 working within the die, and a ram 33 disposed within the tube 31, arranged, combined, and adapted to operate as set forth and shown in the drawings. (8.) In piercing-machinery for making seamless tubes or hollow bodies, the metal die 1, the main piercing-ram 12 and cylinder 11, and the tube or cylinder 31 disposed between the ram 12 and die 1, and its front end working within the die 1, substantially as set forth and shown in the drawings. (9.) In piercing-machinery for making seamless tubes or hollow bodies, the metal die 1, the main piercing-ram 12 and cylinder 11, the cylinder 31 disposed between the ram 12 and die 1, with its front end working in the die 1, and the ram 33 disposed within the cylinder 31, the said ram 12 and die 1 being connected together, substantially as set forth.
