Description
May 12, 1931., J GILL PIPE FULLER FOR REMOVING on PULLING PIPES OR GASINGS FROM WELLS AND THE LIKE Filed April 20, 1929 Patented May 12, 1931 rrsn STATES J RAY GILL, OF PORTLAND, MISSOURI PIPE FULLER FOR REMOVING 0R PULLING PIPES 0R LIKE Application filed April 20,
This invention relates to an improvement in a pipe puller for removing or pulling broken pipes or casings from drilled wells or the like and has for its primary object the purpose of providing improved clutching or gripping means which form part of the puller for gripping the inner surface of the pipe to be withdrawn.
Another object of the invention is to provide the pipe puller with clutching means that are actuated outwardly against the interior of the pipe when withdrawing action is given to the puller.
A further object of the invention is in providing the pipe puller of an improved form which can be readily inserted into the pipe to be withdrawn ready for gripping cooperation with the pipe.
Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had in the accompanying drawings, exemplifying the invention, and in which Figure 1 is a vertical section of this improved pipe puller showing it mounted in a pipe length or casing in gripping coopera tion therewith.
Figure 2 is a vertical section taken approximately on the line II II of Fig. 1.
Figure 3 is an enlarged transverse sectlon taken approximately on the line IIIIII of Fig. 1.
Referring by numerals to theaccompanying drawings this improved tool 1s comprlsed of a pair of longitudinal side members 1 which are secured in abutting relation at their lower pointed ends 2 and are held in spaced relation above the pointed end 2 by spacer members 3 and 4.
Transversely disposed in the members 1 above each spacer member 3 is a pin 5 and swingable on each pin is a gripping dog 6 each having an arcuate surface 7 which is provided with gripping teeth 8. Cooperable with each dog is a leaf spring 9, each leaf spring tending to force each dog outwardly from between the members 1 and in the event that the puller is in removed position with respect to a pipe or casing, the lower bevel casinos FROM wnLLs AND THE 1929. Serial No. 356,683.
In the operation of this improved pipe puller, in the event that it is required to remove a length of broken pipe such as 14 from the bore formed while making the well, the attaching chain 13 is secured thereto and the pointed end 2 of the puller is inserted in the upper end of the pipe to be withdrawn and as the construction of this improved puller is relatively heavy, the puller will be lowered by gravity in the pipe and as the projecting end of each dog 6 engages the wall of the pipe, it will be forced inwardly against respective springs 9. l/Vhen the puller has been lowered to the desired position within the pipe to be withdrawn, a lifting movement is appliedto the pulling chain and the teeth 8 of the arcuate surface 7 of each dog 6 will engage against the inner surface 15 of the pipe 14 thereby forcing the rear longitudinally extending edges 16 of the members 1 which are disposed opposite from the teeth of the dogs, and thus the puller will be firmly held against slipping in the pipe and the pipe will therefore be withdrawn from the well bore.
' IVhile the disclosure of this improved pipe puller is of a built up construction, it is ob; vious that the side members 1 and spacer members 3 and 4 can be formed integral and the dogs and their supporting pins can be inserted in the spacings provided between the members 1.
After the pipe has been withdrawn from the well bore, the removed pipe is held in a perpendicular position so that the pointed end 2 of the puller in the pipe will be directed towards the ground and the puller will fall by gravity from the pipe.
What I claim is 1. A pipe puller comprising a pair of vertically extending side members, and a spring actuated dog having an arcuate gripping-surface supported between said side members lower ends formed adapted to engage the interior of a pipe length when the puller is mounted in the ipe and force opposing edges of said mem ers against the opposite side of the pipe.
2. A pipe puller comprising a pair of vertieally extending side members pointed at their lower ends, and a pair of spring zeta: ated dogs each having an arcnate gripping surface supported between said side members adapted to engage the interior of a pipe length when the puller is mounted in the pipe.
3. A pipe puller comprising a pair of side" members having spaced upper ends and their in abutting relation, a pair of gripping dogs disposed one above. the other between the spaced ends of said membersflon one side only of said members, and resilient means for actuating said dogs J RAY em
