TOOL FOR RAISING SUCKER-RODS FROM WELLS.

SPECIFICATION forming part of LettersPatent No. 299,254, dated May 27, 1884. Application filed December 12, 1882. Renewed March 19, 1884. (Model.)

To all whom it may concern.-

Be it known that I, MARVIN NEWTON, of Knapp s Creek, in the county of Gattaraugus and State of New York, have invented a new and Improved Tool for Raising Sucker-Rods from Wells, of which the following is a full, clear, and exact description. I

With the tools heretofore employed for fishing sucker-rods from wells it often occurs that they cannot be passed down over the rods on account of the straps being broken and bent outward against the tubing, and such tools will also frequently lose their hold and the rod drops back into the well.

The object of my invention is to provide a tool that shall be reliable under all circum stances.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal section of my improved tool, showing the same as attached upon a pump-rod. Fig. 2 is'a side elevation of the same, partly sectional. Fig. 3isahorizontal section of the tool.

A is the tool, consisting of a tube or ferrule of suitable length, and of a diameter for pass ing freely-down over the rod and within the tubing. The tube is formed of thin sheetst-eel. and made with a slit, a, at one side, which slit is normally retained slightly open by the spring of the metal, so that it allows the lowerend of the tube A to spring inward when passing the joint of the tubing, and then spring outward again in order to fill the tubing. The lower end of the tube is made with a level, I), which forms a point at one side, and a cutting-edge. \Vithin the tubing, at or near the lower end, is a fiat spring, a, which is attached at one of its ends and projects upward within the tubing, the spring being bent outward toward the center of the tube. At

its upper end are straps d d, to which the rod eis connected for lowering and raising the tube, and to this upper end are also connected spring-arms f f, which are attached at opposite sides of the tube, and project inward over the top of the same, their ends being formed with chisel-edges.

In using the tube, it is passed down within the well-tube and around the pump-rod, and in case the straps of the rod are bent outward against the tubing, or if the rivets project to interfere with the downward movement of the tool, its lower edge, being formed as a cutter and of steel, will cut them off. The tool is passed down until the spring-arm c, at its lower end, passes beneath the collar on the pump-rod at a point where the rods arescrewed together. As soon as the spring 0 passes this collar it will spring outward beneath the same, so that when the tool is again raised it will bring the rod up with it. The spring 0 extends far enough up into the tube A to prevent the rod from springing out when the tool leaves the upper end of the tubing. Holes 9 are provided in the tube A, for the insertion of a small iron rod to move the spring back to release the pump-rod. In case the pumprod is broken so far from the joint that the spring 0 will not reach the collar, the end of the spring 0 will enter the wooden rod sufficiently far to hold it and allow of its being raised; but in case the spring-c should fail to hold, the two spring-arms f at the upper end of the tube A will enter the rod and hold it securely.

At B is represented a sucker-rod within the tool attached thereon.

I am aware that diagonal cuts at the lower end of tube and a sharp beveled end opposite sprihgarrns on a pump-rod-raising tube and opposite straps on raising-tube, and attached to lifting-rod, are not substantially new; but

WVhat I do claim as new and of my invention is l. A tube for raising sucker-rods, made of spring metal, and with the slit a, whereby the lower end of the metal will spring outwardly when passing a joint, as described.

2. A tube for raising the sucker-rods of a pump, provided with the holes 9 and spring 0, arranged with respect to each other to allow the insertion of a rod for releasing the spring from the pump-rod, as described.

MARVIN NEWTON.
