FISHING T-OO'L.

Application filed. October 17, 1923. Serial 110/669,082.

To all whomz't may concern:

Be it known that DAVID S. TANDY, a citi-' Zen of the United States, residing at VValters, in the county of Cotton and State of Oklahoma, has invented certain new and useful Improvements in Fishing Tools, of which the following is a specification.

This invention relates to fishing tools, and has particular reference to tools of this nature adapted to recover rings and leathers, which havefallen to the bottom of the well tubing, due to the separation of the 621 111 Much difficulty has been experienced in the recovery of such. articles, due to the fact that/it has been difficult to engage and hold the rings, etc., while they are being raised to the top of the Well.

An object of this invention is the provision of a tool of the above mentioned character, so constructed that it will engage the lost rings, etc., by passing therethrough, and will positively hold them while being raised through the tubing. It might be stated here, that several rings or leathers may be recovered at one operation.

A further object of the invention is the provision of means for engaging and recovering lost objects in a well tubing, such as rings, leathers or cagings, which have become disconnected from the operating rod.

A further object of the invention is the provision of a tool of this character, made of a single piece of metal, of simple construction, strong, durable and highly eflicient in use.

Other important objects and advantages of the invention will be apparent during the course of the following description.

Referring to the drawings,

Figure 1 is a side elevation of a tool constructed in accordance with the invention,

Figure 2 is a similar view, taken at right angle to Fig. 1,

Figure 3 is a plan view of the lower end of the tool, and,

Figure 4 is a sectional view taken on line 4.4 of Fig. 1.

In the accompanying drawings, wherein like numerals are employed to designate like parts throughout, 5 designates a cylindrical body having enlarged annular portions 6 and 7, which constitute guides for the tool when being lowered into the'well. The tool has a reduced end which is threaded as shown at 8, for engagementwith a rod (not shown), whereby the tool is lowered or raised in the well tubing. The portion of the body 9, between the annular guides T3 and 7, is flattened as at 10, for engagement with a wrench or other-tool, whereby the engagement may be made with the operating rod, through the mediumof the threaded end 8.

The body 5 of the tool is cut away longi-- tudinally as at'll, forforming resilient contact arms 12 and 13. The cut 11 is enlarged as at 14, to provide greater resiliency to the arms 12 and 13. Adjacent the lower ends of the arms 12 and 13, is formed an enlarged portion 15, forming a shoulder 16. The enlarged portion is threaded as at 17 for en gagement within the internal threads of the caging. The ends of the arms 12 and 13 are further tapered, as shown at 18, whereby the arms will be forcibly guided into the open end of a caging, or through the rings or leathers. The purpose in providing the guide portions 6 and 7, is to insure of the proper travel of the tool through the tubing, it being understood that the body portion 5 is smaller in diameter than the casing, to enable the lost articles to engage about the arms 12 and 13. Tubings of varying diameters will require tools of different sizes.

In using the device, when a cage has become disengaged from its operating rod, it naturally falls to the bottom of the tubing, such disengagement releasing the rings and cup leathers, all of which pass to the bottom of the tubing, and stands upright therein. The tool is then secured to an operating rod, and passed down through the tubing and into engagement with the lost articles. It should be understood, "that all the articles mentioned are of such construction as to allow the tool to pass therethrough. Forcing I wardly, will provide a firm connection. The

tapered ends 18 are the means whereby the arms are forced to contract and enter the lost articles.

It will be obvious from the foregoing that an extremely simple and efficient tool has been provided, one which will easily engage and positively hold several articles while being raised to the top of the well. The device can be very cheaply manufactured, due to the fact that it is made of a single piece of material, and possesses no moving parts likely to become worn or misplaced. The guides 6 and 7 keep the tool in proper position to engage the rings, etc., at all times during its travel through the tubing, and the tapered ends 18 will insure of the entrance of the tool through the several lost articles.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred one, but that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the inven tion or the scope of the subjoined'claim.

Having described my invention, what I claim is:

A tool of the character described formed of a single piece of metal and spaced annular guides formed thereon for engagement with the sides of the well tubing, said tool provided with a reduced screw threaded end for engagement with an operating rod, a pair of spaced resilient gripping arms formed on the tool, the ends of said arms being tapered, an enlarged annular collar formed on the gripping arms adjacent their ends, said enlarged collar provided with screw threads for engagement with the internal threads of a well cage, said enlarged collar forming a shoulder to engage under and hold a ring or leather against displacement when said arms have been forced therethrough, said tool provided with fiattened portions to be engaged by a wrench.

In testimony whereof I afiix my signature.

DAVID S. TANDY,
