WALTER V. REICHARD, OF PAOLA, KANSAS.

ROD-LINE STRETCHER AND WELL BUMPER.

Application filed October 10, 1921. Serial No. 508,702.

T all whom it may concern:

Be it'known that I, IVALTER V. REIOH- ARI), a citizen of the Uni-ted States, residing at Paola, in the county of Miami and State of Kansas, have invented certain new and useful Improvements in Rod-Line Stretchers and lVell Bumpers; and I do declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved device for use in connection with a pull-line for operating a pump of an oil well, and one object of thetinvention is to provide a device by means of which the pull-line may be let out and thus the pump permitted to strike in the bottom of the well so that the pump may be bumped and thus a valve which has hung be shaken loose and caused to operate properly. It often happens that the valve will be clogged by thick oil or by some other obstructions and in order to permit of the pump being lowered and then again very easily raised to the normal position that this device was produced.

' .Lainother object of the invention is to provide av device which can be used in connection with a pull-line of an ordinary construction and may be substituted "for the usual link or elongated hook which connects the end of the pull-line with a ring at the end of the power line.

Another object of the invention is to provide a device which will consist of a comparatively :tew number of parts, all o'l which will be simple in construction and easy to operate and properly adjust during lowering and raising of the pump in the well.

This invention is illustrated in the aocompanying drawings, wherein:

Figure 1 is a perspective view showing the attachment in place andthe pull-line in one position.

Figure 2 is a perspective view shmving the pull line moved to another position.

l igure 3 is a perspective view showing the pull-line in still another position.

Figure 4; is a sectional view through one of the grapples forming a part of the attachment.

- This device is for use in connection with a conventional structure of pump operating power line and pull-line. In oil wells, it is customary to provide a )OWQI' line 1 which is connected with a suitable source of power so that it may be let out and then drawn in and this operation repeated. This power line has one end connected with a ring 2 with which any number of pull-lines 3 may be connected. Each of the pull-lines 3 is provided at one end with a grapple lhaving at its free end a hook 5 and intermediate its length provided with a spur or hook 6. Under ordinary circumstances, the pull-line 3 is to be connected with the ring 2 by means of a. link or bar 7 provided at its ends with hooks 8 for engaging the ring 2 and hook 5. In the present illustration, there has been shown two of the pull-lines, one of which is connected with the ring 2 by means of this link 7 and the second or which is connected with the ring by means of the improved attachment to be hereinafter described. Below the pull-1ines or rod lines 3, there has been shown what is known as an oil-hook and is in the form of an anchor rod 9 which will Figs. 1, 2, 3 and 4r. and each of these grapples consists of a book 13 which is loosely mounted upon a. ring or hanger 14 through which passes the chain 11. This ring or hanger is provided with a handle or tongue extension 15 by means of which the hanger may be easily moved alongthe chain. In order to permit the grapples to be releasably but securely held in place upon the chain, each hanger is provided with a slot 16 which leads from the eye l4- into the handle 15 and is of the proper width to permit a link of chain to be placed in the slot with an adjoining link engaging the face of the handle upon opposite sides of the slot and prevent the chain. from moving through the guard in one direction. It will thus be seen that the grapples of this chain may be secured in the desired positions when the device is in use.

lVhen the oil pump is being operated, the pull-line 3 is connected with the ring 2 of the power line 1 by means of the hook 7 and as the power line 1 is let out and drawn been let out.

in, the pump will be operated in the usual manner. When the pump becomes clogged with thick oil and it is desired to bump the well, the improved device will be brought to a point upon the field adjacent the position of the hook 7. The rod 9 will then be swung upwardly so that when the power line is let out, the spur 6 of the grapple 4 will engage the eye 10 as Shown in 1. The line 3 will thus be held by this hook or grapple l and the hook 7 can be easily removed. The ring 12 will be placed upon the book 5 and the end grapple of the chain will have its hook 13 connected with the ring 2 of the power line 1, The chain will be moved into the notch of the hanger of this end grapple and upon the return movement of the power line 1, the pull-line 3 will be drawn upon and the hook 6 moved out of engagement with the eye. Vfhen the power line 1 again advances to lower the pump into the well, the power line and pull line 3 move to lower the pump in the well, and the heck of the second grapple of the chain will engage the eye 10 as shown in Fig. The line 3 will be held by this hook and as the power line continues to advance, the

chain may be released from the hanger oithe first grapple and slipped through the eye 14 until the desired amount of chain has Upon the return stroke, this slack between the two grapples will be taken up and the hook of the second grapple will be moved out of engagement with the eye 10. When the power line is again let out, the pump should strike the bottom of the well as the power line is let out and drawn in, and the bumping of the pump in the bottom 01" the well will cause the valve to be severely shaken and any obstructions thus removed. Of course, if it is found that the pump does not strike properly in the bot tom of the well, the hook of the second grapple can be again brought into engagement with the eye 10 and the proper adjustment made. After the bumping has been completed, the hook oi the second grapple will be first brought into engagement with the eye 10 and the grapple which engages the ring 2 will then be moved along the chain and locked in engagement with the chain. The pull of the next rewind stroke will bring the hook 6 into position for engaging the eye 10 and with the line 3 held by the grapple l, the attachment can be removed and the hook 7 replaced. It should be further noted that in case the line 3 should break, the hook 7 can be removed and the two end portions of the line brought together and spliced and the attachment then put in place so that the pump can be drawn upwardly from the well and the hook 6 engaged with the eye 10. After this hook is in engagement with the eye 10, the attachment can be removed and the hook 7 put in place. It

will thus be seen that with this device, a pump which has its valve clogged can be easily freed of the obstruction and again put in operation. It will also be seen that by means of tiis device, a splice can be easily made in a broken line.

I claim:
