Abstract

Official abstract text for this publication.

A shank spacer member and its attachment to a pipe wrench is described. The shank spacer member prevents contact between a pipe or other work piece and a shank portion of a movable jaw when the pipe is positioned in the wrench. Upon application of torque to the wrench, the member and its placement on the wrench provides increased gripping force by the wrench upon the pipe.

First claim

Opening claim text (preview).

What is claimed is: 1. A wrench comprising: a handle with a stationary lower jaw portion; a movable upper jaw having a depending shank, the shank including a threaded region; a sleeve rigidly connected to the handle, the sleeve defining a channel sized to moveably receive at least a portion of the shank of the upper jaw; a rotatable member threadedly engaged with the threaded region of the shank of the upper jaw, the member rotatably secured to at least one of the handle and the sleeve, wherein upon rotation of the member the distance between the lower jaw and the upper jaw is selectively adjusted; and a spacer member disposed along a face of the shank of the upper jaw and extending from the upper jaw to at least one of the handle and the sleeve, to thereby preclude contact between the shank and a work piece disposed between the lower jaw and the upper jaw, wherein a modulus of elasticity of the spacer member is less than a modulus of elasticity of the upper jaw. 2. The wrench of claim 1 wherein the spacer member includes a rigid material. 3. The wrench of claim 1 wherein the spacer includes a deformable material. 4. The wrench of claim 1 wherein the spacer member includes a material selected from the group consisting of nylon, polystyrene, polyester, polypropylene, polyethylene, poly (tetrafluoroethylene), and combinations thereof. 5. The wrench of claim 1 wherein the spacer member extends alongside the face of the shank of the upper jaw but is not affixed thereto.
