I ,ADJUSTABLE r lsnnve TOOL.

Application filed June 19, 1924. Serial at. 720,933.

To all whom; it may concern: 1 v Be it known thatI, JORDAN Fox, a citizen of the United States, residing at Mexia,

in the county of Limestone and State. of.

Texas, have invented certain new and useful Improvements in' Adjustable Fishing Tools of which the following is a specification.

This invention relates to fishing toolsfor oil or other wells, and refers more particularly to a device of this character which is simple of construction and which will securely engage the object to be lifted. An object is to provide a device of this nature which will be easily adjusted for operation and which is peculiarly formed to slip over the object to belifted and guide same into contact with the gripping mem-V bers of the device. I

A still further object is to provide a device which will have the weight of the ob-.

ject lifted, distributed ,or directed into th e body 'of the deviceIin a direction longitudinal with the walls of the device, thus avoiding excessive lateral pressure.

A feature of'the invention, it will be observed, is the fact that the tool is so constructed that there are no projections on the outer periphery that mightinterfere with or hinder the progress ofthe'toolup and down" the casing.

Another feature is the adjusting principles of the gripping means. i Other objects and features, as. well a those hereinbefore mentioned, may be more readily understood by following the description herewith, ofwhichthe annexed drawings form a part, and in which: 1

Figure 1 represents a side elevational view ofv the invention.

Figure 2 shows a sectional side elevation of the invention with the body extension member.

Figure 3 is a cross section of Figure 1. Figure 4: is a cross section of; Figure 1 at points 4-4.

Following the figures: 1 denotes the upper portion of the cylindrical body of the springs apply against jaws 3-3 which arejournaled on pins 5-5 in the body 2. They butts of these jaws are rounded at points 3 in conformable fitting to seats in the body wall so that pressure on the jaws applies against the body in a downward direction and that pressure is not exerted on the pins j themselves. These jaws have teeth B on the upper edges thereof.

It will be observed by reference to the drawings that the tool is provided in its upper element with a series ofapertures 1 in order that the liquid may be provided with an outlet when the device is being lowered intothe casing. In the lower portion of the'body, an inner flare 6 ismade which enablesthe tool to receive more effectually the object to be. lifted.

At the top of the member 1 a shoulder 7 is formed on the stem 8, which-has a square shoulder 7 to allowthe purchase of a wrench for screwing the member 1 down on the member 2, or upon the extension 6. In the latter case the extension is screwed upon the member 2. 1 j I In operation, the tool is assembled and lowered in the well over the object to be raised. The jaws grasp this object as soon as the device is lowered over it, as the springs bring them into engagement with the object, grasping it on all sides and the tool is lifted from the 'well with the object within it. I

It should be understood that the extension is used whenit is desired to grasp a longer object. v

It will also be observed, by reference to: Figurel of the drawings that the device has an elongated stem upon the upper porbroken off in the well.

It should also be understood that various minor changes may be made in the construction and arrangement of the invention without departing from the spirit and intent of the following claims:

1. A fishing tool including an elongated tubular bodyhaving diametrically opposed slotted apertures in the walls thereof paired spring controlled toothed gri ping jaws v mounted in the slots of each 0 said apertures, one pair disposed above the other at right .angles thereto; shoulders on said jaws, and projections on the inner periphery of said tubular body to engage the shoulders of said jaws on the downward movement thereof.

2. A fishing tool including a hollow cylindrical body in sections; a pair of diametrically opposed gripping jaws pivoted in the walls of the lower body section; a second pair of diametrically opposed gripping jaws disposed below the first named jaws at right angles thereto; lateral shoulders on each of said gripping jaws; projections on the inner periphery of said lower body section engageable by the shoulders of said gripping jaws, and means for normally holding said jaws in such engagement.

In testimony whereof I have signed my name to this specification.

JORDAN E. FOX.
