Well Column Pipe Holding Tool

Abstract

A tool for holding a well column pipe, the tool incorpo-rating a plate having a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end; a seam extending oppositely laterally from the plate's lateral end, the seam dividing the plate into longitudinal and oppositely longitudinal segments; a hinge connected operatively to the plate at a lateral end of the seam; a releasable latch connected operatively to the plate at an oppositely lateral end of the seam; a jaw connected operatively to a segment selected from the group consisting of the plate's longitudinal segment and the plate's oppositely longitudinal segment, the jaw being adapted for frictional engagement with the well column pipe; and a jack screw actuator for driving the well column pipe against the jaw.

1 . A tool for holding a well column pipe, said tool comprising:
 (a) a plate having a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end;   (b) a seam extending oppositely laterally from the plate's lateral end, said seam dividing the plate into longitudinal and oppositely longitudinal segments;   (c) a hinge connected operatively to the plate, the hinge being positioned at a lateral end of the seam;   (d) a releasable latch connected operatively to the plate, the releasable latch being positioned at an end of the seam;   (e) at least a first jaw fixedly attached to or formed wholly with a segment selected from the group consisting of the plate's longitudinal segment and the plate's oppositely longitudinal segment, said jaw being adapted for frictional engagement with the well column pipe; and   (f) means for driving the well column pipe against the at least first jaw.   
     
     
         2 . The tool of  claim 1  wherein the seam has longitudinal and oppositely longitudinal faces, and further comprising longitu-dinal and oppositely longitudinal concavities respectively formed by said faces. 
     
     
         3 . The tool of  claim 2  further comprising a second jaw fixedly attached to or formed wholly with the plate's other segment. 
     
     
         4 . The tool of  claim 3  further comprising a plurality of column pipe biting teeth, said teeth extending from a jaw selected from the group consisting of the at least first jaw and the second jaw. 
     
     
         5 . The tool of  claim 1  wherein the means for driving the well column pipe against the at least first jaw comprise a screw and coupling nut combination, said combination's screw being attached to the at least first jaw, and said combination's coupling nut being attached to the selected segment. 
     
     
         6 . The tool of  claim 5  further comprising turning means connected operatively to an end of the screw and coupling nut combination's screw. 
     
     
         7 . The tool of  claim 2  wherein one of the faces among the seam's longitudinal and oppositely longitudinal faces forms a groove component of a tongue and groove combination, and wherein the other face among the seam's longitudinal and oppositely longitudinal faces forms a tongue component of said tongue and groove combination. 
     
     
         8 . The tool of  claim 7  wherein the tongue component of the tongue and groove combination has an extension between ¾ inch and 1½ inches. 
     
     
         9 . The tool of  claim 8  wherein the hinge comprises a first clevis joint, wherein said joint comprises a tang, and wherein the tang comprises a lateral end of the tongue and groove combination's tongue. 
     
     
         10 . The tool of  claim 9  wherein a lateral end of the tang is circularly relieved. 
     
     
         11 . The tool of  claim 10  wherein the releasable latch comprises a second clevis joint. 
     
     
         12 . The tool of  claim 11  wherein the second clevis joint comprises a pull pin and alignable eyes combination, and wherein said combination's alignable eyes extend through an oppositely lateral end of the tongue and groove combination. 
     
     
         13 . The tool of  claim 4  wherein each tooth among the plurality of column biting teeth comprises a “V” ridge. 
     
     
         14 . The tool of  claim 13  wherein the plurality of column biting teeth comprises an uppermost tooth and a lowermost tooth, and wherein the uppermost tooth is upwardly displaced from the lowermost tooth a distance between ½ inch and 2 inches. 
     
     
         15 . The tool of  claim 1  wherein the means for driving the well column pipe against the at least first jaw comprise a second hinge connected operatively to the at least first jaw. 
     
     
         16 . The tool of  claim 15  wherein the at least first jaw comprises a pivot arm having proximal and distal ends, wherein the second hinge is positioned at the pivot arm's proximal end, and wherein the distal end of the pivot arm is adapted for frictionally engaging the well column pipe. 
     
     
         17 . The tool of  claim 17  further comprising a second jaw fixedly attached to or formed wholly with the plate, the second jaw being positioned oppositely from the at least first jaw. 
     
     
         18 . The tool of  claim 17  wherein the second jaw is fixedly attached to the plate, and wherein said fixed attachment comprises a jack screw actuator adapted for alternatively moving the second jaw toward and away from the at least first jaw.
