Williams, White & Co., of Moline, III.,are making some forging machinery thatought to form a part of every first-classblacksmith shop equipment. The toolswe illustrate, and particularly desire to callattention to, are a steam bulldozer, an is bolted; this face plate is placed eccentri-cally with the mandrel, so as to make theeye as round as possible and not too flatin shape. The overhanging steel hook onfront of the machine has a movement up-ward and inward; it holds the shank of theeyebolt and brings it up against the sta-. STEAM BULLDOZER.
