Thisv invention relatesL-toimprQvementS swaging machines and more ='particul'arly fin the dies thereof, the object of-theinventionbeing to extend the utility of such machines into 'a far I greater variety of swaging operations than has heretofore been-possible.

The present invention contemplates making the dies separable from thehammer mmbers of the swaging machinefor the purpose of per: mitting relative travel therebetween eitherffo'r' introducing or removing'the dies with' the work'" By this means, work pieces having portionsof irregular cross section i vi'z.', having enlargements between their ends) maybe swaged in a swaging in, a press machme is that of a shifter like protuberances between the ends ofits ta -.g

The die aggregate consists .of two members, a lower and-an upper 6'0" 5 as shown Fig. 3 and "also in the detachedfillustrations Figs. 4' and '5) die, preferably hinged together as at '7. The two dies maythus open like jaws (see Fig. 4) to receive the work pic'efi between their work engaging faces and, when thework is placed therein,

seen from Fig. 5.

The dies have-back portions (upper and lower) ,for slidably fitting in a bearing provided there forfinthe anvil'head 3 of the press.
