WRENCH POLE. 1
Application filed September'l, 1922. Serial No. 585,738.
To all whom it may concern.
Be it known that I, Lonnuzo JACOB S'roNnR, a citizen of the United States, and resident of Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in rench Poles, of which the following is a specification.
This invention relates to wrench poles especially adapted for use in drilling wells.
The wrench poles now in use are very crudely constructed, being formed principally from saplings tied up in the derrick with rope about forty feet from the derrick floor and the wrench balancing weights are blocks of wood tied to the poles with rope making it difficult to obtain the right balance.
Therefore, an important object of this invention is to provide a wrench pole in the nature of a steel I-beam to which a balance weight is slidably connected and which is held in the proper position for balancing the wrench suspended from the other end of the beam.
A further object is to provide a wrench pole of the class described which may be conveniently attached, which is durable in use and cheap to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a fragmentary perspective of the improved wrench pole applied.
Figure 2 is an end elevation of the same.
Figure 3 is a perspective of the balancing Weight embodied in the invention.
In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 generally designates an I-beam formed from steel or other suitable material and which is connected adjacent one end to an attaching hanger 6 the upper portion of which is,
formed with a hook 7 adapted for engaging one of the beams 8 of the derrick. The hanger 6 is connected to the beam 5 through the medium of a U-shaped clevisor attaching member 10 the terminal portions of which are formed with eyes 11 for the reception of a fastening bolt 12. The fastening bolt 12 is, of course, extended through the web of the I-beam and pivotally connects the coupling 1O tothe beam.
That end ofthe beam 5 adjacent the bolt 12 is provided with a U-shaped hanger 13 from which a flexible wrench supporting element 14 is suspended and, as illustrated in Figure 1, a wrench 15 is connected to the lower portion of the member 1%.
Figure 1 illustrates that a balancing weight is formed with a longitudinallly extending T-shaped groove 22 for the reception of the upper flange and the web of the beam. A holding bolt 25 is passed through an opening 26 in the weight and through any one of a series of openings 28 1 in the web of the beam. By means of the spaced openings 28 and the bolt 25 the balancing weight may be readily and conveniently adjusted for use in connection with wrenches of various weights.
As the result of extensive use of the improved wrench pole the same has been found to be extremely reliable, durable and elficient. The wrench when not in use lays flat on the derrick floor and may be readily raised to operative position on account of being prop erly balanced Also, a wrench pole constructed in accordance with this invention may be conveniently installed and adjusted for use under a variety of conditions.
I claim 1. A wrench pole for use in oil and gas well operations comprising an I-beam, a wrench supporting member connected to one end ofthe beam, the other end of the beam being provided'with a seriesof openings, and a balance weight having a T-shaped groove receiving the upper flange and the web of said beam, said. weight being provided with a fastening bolt selectively extending through one of'said openings where y to ad justably connect the weight to the beam whereby to balance the wrench.
2. A wrench pole comprising an I-beam, a balance weight having a groove receiving said. beam, means adjustably connecting the weight to the beam, a coupling member connected tothe beam between its ends, a hanger connected to said coupling, a U-shaped connecting member having connection with one end of said beam, and'a flexible wrench supporting member suspended from said LL shaped connectin member.
