Description:
Quick adjusting pipe wrench; it incorporates a gripping pawl and rack teeth on the movable jaw analogous to similar elements in patent no. 606,317.

A known example is marked with the earlier patent date on the movable jaw -- possibly representing use of existing parts that could also be used in production of that design.
