Abstract

A conventional pipe wrench of the pipe including an elongated handle defining an endwise outwardly facing first jaw element on one end, a laterally offset longitudinally extending sleeve portion on the same handle end, an L-shaped jaw including short and long legs with the long leg slidably received in the sleeve portion for longitudinal shifting therethrough and the short leg opposing the aforementioned first jaw element and defining a second jaw element, and thrust structure operatively connected between the long leg of the L-shaped jaw and the handle for shifting the L-shaped jaw longitudinally of the handle, the improvement comprising a laterally outwardly projecting heel portion carried by the end of the long leg of the L-shaped jaw from which the short leg is supported and projecting laterally outwardly of the long leg in a direction opposite to the direction in which the short leg projects and with the heel portion extending outwardly beyond the sleeve portion in a manner such that the back of the wrench may be supported from a planar surface by the free end of the end heel portion and the end of the handle remote from the first jaw element with the jaw elements projecting away from the planar surface and the sleeve portion spaced from the latter.

Dependent claims

In a conventional, self tightening pipe wrench of the type including an elongated handle defining an endwise outwardly facing first jaw element on one end, a longitudinally extending sleeve portion on said one end, an L-shaped jaw including a long leg slidably received through said sleeve portion for longitudinal shifting along said handle and a short leg disposed at generally right angles to said long leg and defining a second jaw element disposed outwardly of and opposing the first jaw element for movement toward and away from the latter responsive to movement of said long leg toward and away from the other end of said handle, jaw shifting means operatively connected between said handle and long leg for adjustably shifting the latter along said handle and wherein angular displacement of said handle about an object engaged between said jaws, when the free end of said handle is swung in the direction in which said jaws open, causes said jaws to tighten their grip on said object;

the improvement comprising a projection on said L-shaped jaw adjacent the juncture between said short and long legs and projecting outwardly from the side of said long leg remote from the side thereof outwardly from which said short leg projects, said projection extending outwardly from said long leg a sufficient distance to abut a planar surface facing in the direction in which said short leg projects, spaced outwardly of said long leg, sleeve portion and jaw shifting means and with which the other end of said handle is also abutted.
