Plumbing insert removal tool

摘要

An internal plumbing wrench is arranged for internally gripping a plumbing insert, such as those used in sinks and the like. The internal wrench includes a split gripping section which is adjustable by the cam action of a hexagonal core. A central shaft has a foot extending 90° away from the longitudinal axis of the shaft and is arranged to extend into pipes connected to the insert to hold a broken pieces and permit separation of the insert from any pipe pieces attached thereto.

主权项

1. An internal wrench configured to operate in an environment including of a first run of pipe with an open end having an insert with a threaded connector attached to the open end, the first run of pipe extending in a first direction, a second run of pipe extending in a second direction approximately 90° from the first direction, wherein the first and second runs of pipe are connected by a substantially 90° angle connector, structurally configuring the first and second runs of pipe so that a torque applied at the open end of the first run of pipe creates a potential breaking point along the second run of pipe; said internal wrench comprising:
a) a split gripping section; b) a core section having a longitudinal axis and arranged within said split gripping section, the core section being operable to adjust separation characteristics of said split gripping section; c) an elongated central shaft arranged within said core section along the longitudinal axis of the core section; and, d) a foot section extending from the elongated central shaft in a direction substantially 90° from the longitudinal axis of the core section, and comprising means for holding said second run of pipe by applying distributed force along said second run of pipe on either side of said potential breaking point and preventing rotation of said first run of pipe when torque is applied at said open end of said first run of pipe.
