PULL-BOD (ILA M1.
Application filed January 18, 1928. Serial No. 82,153.
This invention relates to a combination clamp and knockoff block for use with pump mechanism of oil wells and the like, the general object of the invention being to improve the construction of the clamp and to make the block of metal instead 0t wood.
Another object of the invention is to provide an auxiliary clamp wnich is so positioned on the rod line that the lines can be repaired when broken by removing the clamp to permit one section of the broken rod to be pulled partially through a post to meet the other broken end.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing my invention in detail, reterence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a View showing the parts in use with the power line connected with the pump rod.
Figure 2 is a similar View with the parts disconnected.
Figure 3 is an enlarged elevation of one clamp.
F igure t is an end View of this clamp.
Figure 5 is an elevation of the block.
Figure 6 is an end view of the block.
Figure 7 is a section through line 7-7 o1 Figure 1.
Figure 8 is a sectional View of a clamp.
As is well known a plurality of oil well pumps are actuated from a single power plant through means of rod lines and power lines, the rod lines being supported by posts and having means for detachably connecting them with the power lines so that after a well is pumped oii its rod line can be disconnected from its power line. In Fig ures 1 and 2 a rod line is shown at 1, a support post at 2 and a power line is shown at 3. A clamp 4 is fastened to the end of the power line and has its U-shaped part 5 engaging a hook 6 which is connected by the coupling 7 with the end of the red line 1. The pulling of the power line will act through the rod line to lift the pump parts so that when the pull on the vpower line ceases the pump parts will'drop, pulling the rod line and power line to their former, positions and then the operating apparatus again pulls on the power line to again raise the pump parts through the rod line. Thus the pump parts are reciprocated to 'pump the well. When it is desired to detach the rod line from the power line a knock off block 8 is placed between the post 2 and a clamp 9 on the rod line to check the down ward movement of the pump parts and the red line and thus permit the power line to be disconnected from the rod line through the slack occurring" in the power line By placing the clamp 9 a distance from the coupling 7 it the rod should break between the post 2 and the well the rod 1 can be moved forwardly by removing the clamp 9 so that its broken ends can be suitably connected together without removing the coupling 7 or entirely drawing the rod through the post 2. Both the clamps 4 and 9 are provided with circular or extended bases, as shown at 10, so that they will each have a large fiat surface to engage the knock off block and the clamp e is provided with covered holes 4 to receive the ends of the U- shaped member 5 and thus prevent said ends from forming projections. The knock off block 8 is made of metal and is formed with wide ends 11 for engaging the post and the circular base of the clamp and it is also provided with a groove 12 which extends through the ends and the body to receive the rod 1. The block is also provided with a handle 13. Thus the block cannot be damaged as a wooden one might be and it is easily handled.
In some cases a clamp similar to the clamp 4 may be connected with the end of the front rod, as shown in Figure 3, in which the clamp is shown at 4: and the rod at 1; In this case the clamp is connected directly with the end of the rod. When this arrangement is used the clamp 9 may also be used or omitted, as desired, and a hook would be placed on the power line to engage the U-member of the. clamp t. By making the ends of the clamp flat and of considerable area and the knock off block of metal with large ends, the knock ofi" block cannot be damaged by projecting portions of the clamps. With my arrangement the rod lines can be easily and quickly detached from the power line by the use of the knock off blocks and repairs can be easily made to the rod lines by removing the clamps 9 to give slack to the broken rods.
As shown in the drawings, the holes 4 are formed by making a pair of semi-circus lar recesses in the inner face of each clamp which, when the two parts of the clamp are placed together will form circular openings to receive the upset ends or headsof the U-shaped part.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the-construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What I claim is 1. A knock off plate formed of metal and 2; A knock off block formed of metal and having wide ends and a groove passing through the ends and body and a handle connected with the body.
3. In combination with a power line and a rod line of a pump mechanism and a sup porting post, a knock off block formed of metal and having enlarged flat ends, one of which engages the supporting post, said block having a groove therein through which the rod line passes and a clamp adapted to be clamped to the rod line and having a wide base for engaging the second enlarged end of the knock ofi block.
In testimony whereof I affix my signa- I ture.
v HAROLD GIBSON DURNELL.
