FISHING-TOOL FOR SUQKER-HODS OR THE LIKE.

SPECIFICATION formingpart of Letters Patent No. 759,454, dated May 10, 1904. Application filed September 30, 1903. Serial No. 175,170. (No model.)

To all whom it may concern:

Be it known that we, OMAR A. MANN and WILLIAM J. EVANS, citizens of the United States, residing at Oil Center, in the county of Kern and State of California, have invented new and useful Improvements in Fishing- Tools for Sucker-Rods or the Like, of which the following is a specification.

Our invention relates to improvements in means for recovering and removing broken sucker-rods or other and similar obstructions from oil-wells.

It consists of the parts and the construction and combination of parts hereinafter more fully described, having reference to the accompanying drawings, in which- Figure 1 is a vertical central section of well, showing our invention. Fig. 2 is a vertical central section of ring portion. Fig. 3 is a bottom view of same. Fig. A is a top view of same, showing latch. Fig. 5 is a section of coupling.

A represents a well-tubing in which operates the usual sucker-rod 2, comprised of a series of separable sections united by suitable couplings 3.

Not infrequently in deep-well pumping the rod breaks or becomes disconnected, whereupon it is necessary to fish out from the bottom of the well the remnant of the rod be-.

fore operations may be resumed.

The object of our invention has been to design a simple durable device which may be lowered into the well, slipped over the end of the broken rod, and engaged with a coupling or like protuberant part on the rod and the latter, with its bucket, drawn upward to the surface. This device comprises a hollow cylindrical section 4 of slightly less exterior di ameter than the interior diameter of the welltubing, so as to be freely reciprocable therein, at the same time not to allow a rod or other tool which is to be recovered to pass between the cylinder and the tubing.

The section is provided with the bail 5, consisting of a suitable number of rods, preferably three, terminating at the top in a union 6, by which the device may be attached to an operating-rod and connected to the section so as to leave suflicient space for the hinging and proper movement of a bifurcated catch or clutch member 7 This catch is pivoted on one side of the top of the section and is adapted normally to bridge over and rest on the end of the section.

The inner sides of the catch are parallel, and the width of the intervening space 8 is in excess of the diameter of a sucker-rod, but less than the diameter of a coupling 3, since the device is adapted to be lowered over a rod, the rod passing up through the cylinder and between the arms of the catch, lifting the latter to allow it to pass below a coupling. When the device is lifted, the catch engages beneath the coupling, and the rod is lifted to the surface.

The bottom edge of the cylinder is beveled, as at 9, so that ordinarily in lowering the device and engaging a broken rod, which usually leans against the tubing, the rod will be fed into and through the cylinder. However, in order always to insure the engagement of the rod by the device the cylinder is provided with a notch 10, having a vertical wall portion 11, beveled outwardly to form a sharp edge which will cooperate with the tubing when the device is turned in the right direction on striking the top of a rod to draw the rod into a cylinder. The device is then lowered over the rod, the latch lifting to permit it to ride over a coupling and then'dropping back on top of the section and straddling the rod. On the device being drawn out of the well the broken rod is carried with it. In engaging the rod through the agency of notch 10 and wall 11 any suitable means may be employed to rotate the deviceas, for example, a pipe-wrench, as shown at 12, gripped to the operating-rod 13, carrying-cylinder 4, and turned by hand.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is"- 1. A device of the class described comprising a suitable body having a central opening and a hinged bifurcated clutch member normally resting on the top of said body and bridging said central opening.

2. A device of the class described comprising a hollow cylindrical section, means for connecting it to an operating-rod, and a slotted plate hinged to one side of the section and normall y bridging the opening therein.

3. A device of the class described comprising a hollow cylindrical section, and clutch mechanism carried by said section, and comprisinga pivoted bifurcated member normally resting on top of the section and across the central opening thereof said section having a beveled part to cooperate with the tubing to engage and direct the rod or other obstruction which is to be recovered into the section.

4. A device of the class described comprising a hollow rotatable cylindrical section and clutch mechanism carried thereby, said sec- 5 tion having a notch in its under side and said notch having a vertical beveled Wall adapted to cooperate with the Well-tubing.

In testimony whereof We have hereunto set our hands in presence of two subscribing wit- 2
