The arrangement shown in Fig. 4 is used for making brakeshaft bearings or other forgings of this character. Two sepa-rate blocks, cut out to give the desired shape, are held by twolinks, as shown, one on each side. The bar to be forged is placed. Fig. 2—Wood Bits for Car Work.

The plunger B, which may beapplied tu an air press or may be in the form of a set drivenby a sledge hammer, then forces the iron bar into the die. Atabout one-half its stroke the wooden block or plug that holdsthe two dies open should be removed, allowing the blocks tofall on the level surface, as shown at C.
