The upper casting is constructed to receive a har-dened steel die (c) which can be changed for each di-ameter of stem desired and thus the tool is adapted toa wide range of work. At (a) is a lever on which the endof the stem rests when the head is upset. It is also used for forcing the pieceout of the tool. This tool is a combi-nation upsetting andheading tool. The piece(a), which can be set atany desired position inthe space (6), is placedso that the distance fromthe top of the die (c) tothe top face of (a) is the length of the required stock must be cut just the right length (determinedby calculations).
