UNITED STATES WILLIAM F. GOURLEY, OF GOOD PINE, LOUISIANA.
WRENCH.
Application filed January 15, 1926. Serial No. 81,486.
This invention relates to wrenches and has particular reference to a wrenchfor manipulating substantially circular objects such as pipe.
The primary object of the present lnvention is to provide a wrench which may be easily and quickly engaged or detached from a pipe or similar object, and when so engaged, shall firmly grasp the same and facilitate rotation or lifting thereof.
Another object is to provide a wrench which while capable of general use, shall be especially adapted for use in connection with well casings which are usually disposed'in a vertical position and coupled and uncoupled by a rotary movement.
A further object is to provide a wrench of this general character which shall consist of few parts that are simple in construction, and inexpensive to manufacture, and whlch may be easily and quickly assembled.
lVith these and other objects in View, the invention may be stated to consist in the Various novel features of construction and arrangement or combination, all of which will be fully described hereinafter and pointed out in the appended claims.v
In the drawing accompanying and forming a part of this application z- Figure 1 is a plan View of a Wrench constructed in accordance with my invention, and showing the same applied to a pipe, the latter being shown in section; and
Figure 2 is a side elevation thereof but Y showing the wrench applied for rotation of the pipe in an opposite direction.
In constructing a wrench in accordance with my invention, I provide a pair of oppositely disposed handle members 1 and 2, each of which is formed with an arcuate inner end portion 3 and 1 respectively. As shown in Figure 1, I preferably provide the engaging surface of arcuate portion 3 with a roughened or serrated surface 5 which may be formed integral therewith or on a detachable jaw member 6 that is removably connected to portion 3 by means of screws 7 or other suitable fastening means. It will be noted at this point that although I show portion 3 serrated and portion 4 smooth, I might form either or both of these portions smooth or serrated as desired.
The oppositely disposed handle members are pivotally interconnected by a pair of links 8 fastened to the arcuate inner end of one handle member by a pin 9 and to the opposite handle member by a pin 10 at a point intermediate the handle and arcuate portion formed thereon. While the wrench constructed as thus far described consists of an operative structure, I preferably provide, in addition, a third jaw member 11 also arcuate in shape and having serrations 12 on its inner peripheral surface. This jaw member is pivoted to handle member 1 at a point intermediate the handle and arcuate portion formed thereon and at its outer end said jaw member is provided with a vertically projecting handle 14 to facilitate operation thereof.
It will be understood that Wrenches constructed as described abovemay be made in various sizes to accommodate within the limits of each size, the various difierent diametersof pipe or well casings. In use, the handle 1 is rotated in a clockwise direction above pivot 9, and handle 2 in a counterclockwise direction about pivot 10 (as viewed in Fig. 1') thereby opening the arcuate jaws of the wrench so that it may be engaged about a pipe 15 or other object. The jaws having received the object to be turned, are rotated in an opposite direction to close thereabout. As shown in Figure 1, the wrench is applied to pipe 15 to rotate the same in a clockwise direction, the serrated portion firmly gripping the cylindrical surface of the pipe, and the jaw 4 exerting africtional grip thereabout and also urging the other jaw 3 into firm contact with the pipe. The operator exerts a forcev in a counter-clockwise direction-on handle 1 and a force in a clockwise direction on handle 2 as the device is rotated in a clockwise direction, as viewed in Figure 1, whereupon the jaws 3 and 4. will tend to tighten about the pipe and prevent slipping. In some instances where slipping might occur due to rusted or corroded joints, such diificulty may be easily overcome by engaging aw 11 about the pipe as shown in dotted lines and pulling the same into firm contact with the pipe by means of handle 14.
lVhen it is desired to rotate the pipe 15 in a counterclockwise direction, the wrench may be applied with the opposite side up, as shown in Fig. 2. This merely serves to reverse the engaging edges of serrations 5 and 12 so that firm engagement with the pipe 15 will be insured. In case of wear,
the jaw 6 may be easily and quickly removed and another substituted.
While I have described my wrench as particularly adapted for rotating vertically disposed pipes such as well casings, it will be understood that it can be used with equal success for lifting such pipes or for IOttItlDg' or lifting horizontally disposed pipes.
I claim:
1. A wrench comprising a pair of oppositely extending handle members each having an integrally formed arcuate jaw adapted to engage about an object, and a link permanently connecting said members together, said link being pivotally connected adjacent one endto one of said handle members, and pivotally connected adjacent the other end to the jaw of the other member.
2. A wrench comprising a pair of op ,positely extending handle members each having an integrally formed arcuate jaw adapted to engage about an object, and a link permanently connecting said members, said link being pivotally connected to the extremity of one of said jaws, and pivotally connected to the other member at a point intermediate said arcuate jaw and the handle thereof. I
3. A wrench comprising a pair of oppositely extending ha'ndle members each having an arcuate jaw adapted to engage about an object, a link pivotally connecting said members together, and a third jaw pivotally connected to one of said handle members and adapted to engage about said object.
4. A wrench comprising a pair of op positely extending handle members each havan' object, one of said jaws having serrations formed thereon and the other of said jaws having a smooth surface, a link permanently connecting said members, said link being pivotally connected to the extremity of one of said jaws and p-ivotally connected to the other member at a point intermediate said arcuate jaw and the handle thereof, and additional means carried by one of said handle .members for engaging about said ob ect.
5. A wrench I comprising a pair of op positely disposed handle members each havmg an arcuate aw adapted to engage about ing an arcuate jaw adapted to engage about an object, one of said jaws having a re movable element provided with serrations, a pair of links pivotally connecting said members, said links being pivotally connect ed at one end to the extremity of one of said jaws, and at the opposite end to the other member at a point intermediate said arcuate jaw and the handle thereof, and a third jaw pivotally connected to the first mentioned handle member at a point intermediate sa'id arcuate jaw and the handle thereof.
In testimony whereof I aiiiXr my signature.
