Abstract
A chain breaker has an interchangeable turret anvil plate mounted on an upper surface of a lower jaw. The lower jaw has a slotted upper portion which extends partially over the anvil plate. An upper jaw has a reduced lower portion which fits within the slotted upper portion of the lower jaw. A retainer pin extends through the slotted portion and holds the jaws together. Near the pin a retaining portion of the upper jaw extends over the anvil plate and the threaded retainer and prevents accidental dislodgement of the anvil plate and threaded retainer. An outer surface of the retaining portion abuts a chain workpiece. A pin connects two handles on a line with the jaw pivot pin, and pins connect individual handles and the jaws on a line which intersects the first line close to the handle pin. A forcer screw in an outer end of the upper jaw carries a breaker tip at its lower end which is positioned just above a cantilevered portion of the anvil plate.
