FISHING-TOOL.

SPECIFICATION forming part of Letters Patent No. 769,140, dated August 30, 1904. Application led November S, 1903. Serial No. 183,099. (No model.)

To a/ZZ whom, it may con/cern:

Be it known that I, CHARLES M. IIEETER, of Butler, Butler county, Pennsylvania, ,have invented `a new and useful Fishing-Tool, of

which the following is a full, clear, and exact; I description, reference being had to the accom.`

panying drawings, forming part of this'speciiication, 1n which- Figure 1 shows in elevation my fishing-toolwhenin use in removing a detached bit or tool from an oil-well.

Fig. 3 is a separate view of the fishing-tool, and Fig. A is a detail view showing the fishing-tool engaged with a diferent portion of the detached bit from that illustrated in Figs. 1 and 2.

The difficulties whichhave heretofore atftended the removal of detached tools or bits from oil-wells have been the occasion of great expense and loss to yoil-well drillers and operators; and it is the'purpose of my invention to provide means for this purpose which shall be reliable in its actionl and which will enablethe removal of bits or tools from wells more certainly and quickly than has been possible heretofore.

My invention consists in a 'lishing-tool of new construction; and it also consistsin a drilling-tool having a lateral recess affording a shoulder for engagement by my fishingetool or by fishing-tools fof other construction.

Inthe accompanying drawings, Fig. il, 2 represents a bit or drilling-tool which has been broken off and lodged in an oil-well. having been crowded against and into the soft rock at the side of the well in a manner which prevents its engagement by fishing-tools or' the kind ordinarily employed. i 3 is the fishing-tool which I Aemploy for removing such'.

bit." This tool consists of a head portion or socket A, by which it is connected to the stem or string of tools 5, 'extending to the top of the well. fishing-tool is reduced in thickness and extends downwardly from one side of the head portion, so that it may be inserted along the side of the bit or tool to be removed, and it is provided with a hook 6,v the extremity or' Fig. 2 is asimilar view seen at right angles to Fig. l.

The lower portion or shank of the 'which is preferably made of hardened steel, so as to insure its engagement with the tool to be removed.

lfrom the fishing-tool preferably below the vhook 6` and when the iishing-tool enters between the bit 2 and the wall of the well is adapted to bear against the wall of the well and to exert upon the fishing-tool a pressure tending to push it toward the bit.

In the use of my fishing-tool it is lowered into the well until it passes between the side it comes opposite to anjupwardly-recessed portion B, which I form for that purpose on the bit or drilling-tool, it is forced inwardly by the spring 7 and when it is next drawn up the hook 6 will engage the recess B and the bit 2 can be drawn with the lishingtool to the top of the well. i

I prefer to for'rnvon the bit 2 one of the recesses B or B on each side of the bit 2. so that the fishing-tool will engage with the bit at tween the bit and the wall. The fishing-tool, however, may be used to remove tools or bits which are not provided with recesses B or B'. In this case if the hook 6 be made of hardened steel the spring 7 will cause it to bite upon well and to dislodge `it from the sides .suie ciently to enable a horn-socket, (which is a common jrisl1in ,rtool,) to be inserted into the well and engage with it, whereas without the preliminary dislodging of the bit it is often difHcult and sometimes impossible to cause the Vhorn-socket to` engage it.

Within the scope of my invention as delined in the claimsthe apparatus may be modified in construction in various ways, since What' I claim isl. A fishing-tool for deep wells havinga hook adapted to be inserted into the space between one side of a lodged tool and the side of the well, and a spring guide or arm adapted to press the hook toward the lodged tool; substantially as described.
