Description: |
| "My invention relates to means whereby, while preserving ease of adjustment of the flexible member to suit pipes of a certain size, and facility of attaching it around and detaching it from different pipes of the same size, the improved pipe wrench grips the pipe only when the lever is pressed in one direction and slides easily over the surface of the pipe when pressed in the opposite direction, thus permitting it to be used like a ratchet spanner, without risk of the flexible member becoming detached from the lever.
In order that the wrench may be used on soft material or polished work, such as copper or nickel plated tubes and the like, without damaging the surface thereof, when the flexible member is made of steel or other hard material, I provide a strap which may be attached to or detached from the underside of the said flexible member at will." -- from the specifications. The adjustment is effected by a nut and threaded shank attached to the flexible member. |
