Figure 8 is an elevation illustrating a modified actuating means or tool of this invention which is adapted to be used for moving, the valve member inan opposite direction to the actuating tool illustrated in Figures 1-7.

Figure 9 is a view, partly in' section and partly in elevation, of a plurality of the valve constructions of this invention mounted in atubing string with: a well packer.

In the drawings, the numeral 10 designates a valve 4 housing which is. tubular and which is connected at its upper end to a. well pipe or tubing 11 which extends to the surface of the well. Thelower end ofthe valve housing 10 is connected to an adapter 12, which in turn, is connected to a lower section of well. pipe 1'4, or, if desired, to a. valve housing identical with or similar to the housing. 10. Thus, the valve housing 10 is positioned, in the well pipe or tubing stringwhich extends from the surface of the well and it actually; forms a-. part thereof, with the bore 10a of the housing 10 being of substantially the same diameteras the bore of the well pipe or tubing string. Within the valve housing 10, there is mounted a valve or valve member 15 which is adapted to. be turned. or rotatedrelative to the housing 10 and. which isformed with a bore 15a therethrough, which is slightly smaller in diameter than the bore. 10:: of. the housing. 10,,but which is also-of substantially the same diameter as the diameter of the bore of the tubing string.

To provide fluid. communication. between the exterior of the valve housing 10 and the bore 15a of, the valve member 15; one or more lateral ports 20; are provided in the valve housing 10, which: are adapted to be moved into and out of alignment with one or more ports. 21- in the valve or valve member 15, whereby the valve is either opened or closed, respectively. For turning the valve or valve element 15 to open or close same, an actuating or jarring means A (Figure l) is provided which is suspended on a cable, wire line, or other similar flexible line P (Fig. 1A) which extends: to the surface of.- the well, whereby the actuating or jarring means or tool A may be lowered and raised thereon and alsomanipu-- lated thereby. As will be explained, the actuating tool. A is so constructed that it can be lowered into'the wellpipe or'tubing string 11', connected to the valve or valve element; 15,.then actuated by a manipulation. of its flexible support line to impart a rotary motion to the valve member 15 to turn same for actuating the valve, and

thereafter the actuating member A can be retracted from.

the well pipe or tubing string 11 for subsequent well operations wherein well tools are passed through the bore 151: of the valve element 15, if desired.

Considering the details of the valve construction of this invention, the valve elementor member 15 has a near the lower end thereof andv adjacent the flow portsv 20'. The lower end of the valve member 15 has a plurality of cams or cam lugs 25 formed thereon, each of which rests upon and is adapted to slide relative to a cam ring 26 which rests upon the upper end 12a of the tubular adapter 12. The upper end of the cam ring 26 is formed with a cam surface which has diametrically opposed high points or portions 26a and diametrically opposed low points or portions 26b, which are positioned between the high points 26a, whereby as the valve member 15 is moved from its open position (Figure 2) to its closed position (Figure 1), the cam lugs 25 ride from the low points 26b of the cam ring 26 toward the high points 26a, so that the valve member 15 is moved slightly longitudinally upwardly to tightly wedge the surface 15b of the valve member 15 into contact with the tapered surface Thus, a tight seal is formed between such metal surfaces 1% and b when the valve member 15 is in the closed position, because, as can be seen in Figure 1, the valve member 15 is raised with respect to the housing 10 when it is in the closed position.

The cam ring 26 is prevented from rotating relative to the valve housing 10 by reason of a key 27, which is mounted on the ring 26 and extends outwardly therefrom into a keyway 28, which is a longitudinal slot or groove formed in the bore 10:: of the valve housing 10 at its lower end. To prevent fluid leakage between the threaded connection of the adapter 12 to the valve housing 10, an O-ring 30 formed of rubber or other similar elastic material is mounted between the lower endrof the valve housing 10 and an annular radially extending shoulder 12b on the adapter 12.

The valve member 15 has a pair of diametrically opposed longitudinal slots 15c (Figure 2) which have upwardly curved walls which converge into diametrically opposed pointed upper ends 15d. The valve member 15 is also provided with a lateral slot 32, which extends in an arc of substantially 90 degrees, but preferably slightly more than 90 degrees, and receives a stop pin 33 mounted on the valve housing 10 (Figure 3). The diameter of the pin 33 is less than the height of the lateral slot 32 so as to permit the longitudinal movements of the valve member 15 relative to the valve housing 10 by reason of t2h6e co-action between the cam lugs 25 and the cam ring The actuating member or tool A, which imparts the turn ng or rotational movement to the valve member 15, includes an outer sleeve 35 (Figure 1) which has its upper end connected to a suitable support, such as a cable or flexible wire line (not shown). A rod 36 is positioned Within the sleeve 35 and the parts 35 and 36 are longitudinally moveable relative to each other, with such longitudinal relative movement being controlled by the movement of a pin 37 extending outwardly from the rod 36 into a shaped guide slot 38 in the sleeve 35. The lower portion 38a of the slot 38 is vertical or substantially vertical and the slot 38 gradually increases in inclination as it progresses upwardly so that the upper portion 38b of the slot 38 is substantially lateral or horizontal. Such construction of the slot 38 results in the rotational movement of the sleeve 35 relative to the rod 36 as the sleeve 35 is permitted to fall by gravity from an extended position to the fully telescoped position shown in Figure 1. Thus, the sleeve 35 would be in the fully extended positwo when the pin 37 is at the lower end of the slot 38 and it is in the fully telescoped position when the pin 37 is at or near the upper end of the slot 38. It should be noted that although the lower portion 38a of the slot 38 is illustrated as vertical, it is generally preferable to provide such lower portion 38a with a slight incline from vertical so that there is no sharp change in the movement of the pin 37 in the slot 38 as the sleeve 35 is dropped.

The lower end of the rod 36 is threaded or otherwise suitably secured to a body 40, and such rod 36 is preferably prevented from rotating relative to the body 40 4 r by a retaining set screw 39 (Figure 2). On the upper end of the body 40, an anvil ring 41 is mounted which has one or more substantially vertical or longitudinal surfaces 41a which are adapted to be contacted by substantially vertical or longitudinal hammer surfaces 35a formed on the lower end of the sleeve 35. The anvil 41 is retained in position on the body 40 since the anvil 41 is formed in the shape of a ring and the rod 36 extends through the bore thereof (Figure 2). Also, a dovetail joint is provided between the anvil 41 and the body 40 by means of the downwardly extending flared projections 41b which fit into complementary recesses 40a.

At about the midportion of the body 40, a longitudinal opening 4% is provided for the mounting of a pair of pivoted latching arms 42. The arms 42 overlap each other in scissor fashion with a pivot pin 43 extending through the overlapped portions of the latching arms 42. The lower portions 42a of the latching arms 42 are urged laterally outwardly by a coil spring or suitable resilient means 44 which is confined between the latching arms 42. The upper portion 42b of each of the latching arms 42 are actually retracting dogs which also extend outwardly from the longitudinal opening 4%, and such dogs 42b also tend to move outwardly and away from each other by reason of the urging of the coil spring 44.

When the actuating tool A is initially lowered into the tubing string 11, the latch arms 42 are held in a retracted position by means of a retaining or lock ring 50 which is connected to the upper end of a slideable shaft 51. The retaining ring 50 has a substantially circular central recess 504: into which fit projections 420 on the lower end of each of the latch arms 42. The retaining ring 50 and the slideable bar 51 are maintained in their upper or locked position during the lowering of the actuating or jarring tool A into the tubing string by a shear pin 52 which extends into an annular notch 53 formed in the slideable bar 51. i

To shear the shear pin 52, a collar finder 55 is pivotally mounted on the member Slat the pivot pin 56 and a spring 57 resiliently urges the finder 55 outwardly through an opening 400 in the lower portion of the body 40. The finder 55 is adapted to seat or catch on the annular shoulder of the adapter 12 upon an upward movement of the actuating tool A after such tool A has been lowered through the bore of the valve member 15 and the adapter 12. A downward force is thus applied to the slideable member 51 to shear the pin 52, whereupon the coil spring 60 which is confined between an annular guide 61 and a nut 62 on the member 51 urges the slideable member 51 downwardly to retract the retaining ring 50 from the projections 420. When the retaining or lock ring 50 is thus moved below the projections 42c, the spring 44 acts to urge the latching arms 42 outwardly so that as the actuating or jarring tool A is raised in the bore of the adapter 12 and the valve member 15, the latch arms 42 are urged outwardly into the longitudinal slots of the valve member 15 to thereby connect the actuating or jarring tool A to the valve member 15. It should be pointed out that the finder 55 is retracted from its extended position shownin Figure 2 to a retracted position shown in Figures 5 and 7 when the shear pin 52 is released and the spring 60 urges the slideable bar or shaft 51 downwardly. Thus, the finder 55 does not interfere with the'upward movement of the actuating or jarring tool A after the lock ring 50 has been released and moved downwardly with respect to the latching arms 42.

With the valve member 15 in the open position and the latch arms 42 engaged in the longitudinal slots or recesses 15c of the valve member 15, the upper portions or dogs 42b of the latch arms 42 are in the same horizontal plane as retracting lugs 75 which are mounted in the bore 10a of the housing 10. One retracting lug 75 is provided for each of the latch arms 42 and the latch lugs 75 age substantially diametrically opposed with re:

newest spect toeach other and are positioned 90 degrees from the latch arms 42 when the valvemember 15' isin the open position (Figures; 5 and 6). 75 are so positioned that their innersurfaces 75a (Figure 6) form a continuation of the inner surface or bore 10a of the valve housing 10, whereby as the dogs 42b move in a rotational direction relative to the valve housing 10, they contact the inner surfaces 75a of the retracting lugs 75 and are thereby moved radially or laterally inwardly, which also eifects an inward movement; of the lower portions 42a of the latching arms 42. The lower portions 42a of the latch arms- 42 are retracted a sufficient distance to retract same from the; longitudinal slots 150 so that the actuating tool A is permitted to then drop relative to the valve member and further rotation of. the valve member 15 is prevented; thus, giving an indication of the completion of the closing of the valve member 15.

In the operation or use of the valve, construction of this invention, the valve member 15' is positioned in the valve housing 10, which is assembled as shown in Figures 1 and 2, so as to form a continuation or a part of the well; pipe or tubing string 11 from which such assembly is suspended. For purposes of explanation, it is assumed that the valve member 15 is in. the open position with its ports 21 aligned with the ports 20. in the valve housing 10 (Figure 2). The jarring or actuating tool A is then lowered into the tubing string 11 and passes through. the bore 15a of the valve member 15 a suflicient distance to position the finder 55 below the annular shoulder 12c of the adapter 12. Then, an. upward movement of the jarring or actuating member A is.effected so that the slideable member 51 is held against upward movement and, as a. result, the shear pin '52 is sheared so that the spring 60 urges the lock ring 50 downwardly away from the latch arms 42 and also retracts the collar finder 55 (Figures 5 and 7) With. the lock ring 50 out of locked position so that the latch arms 42 are expanded, the upward movement of the actuating or jarring tool? A is continued until the latch arms 42 have been raised above the upper ends 15d of the. valve member 15,, whereupon the lowering of the actuating or jarring tool A results in a guiding of, the latch. arms 42 into the longitudinal, connecting slots 15c of the valve member 15 .to therebyestablish a connection between the actuating meansA and the valve member 15. The flexible line supporting the outer sleeve 35 is. then raised. toposition the pin 37v in the lower portion. of the shaped slot 38, if such pin 37 is not already in that position. Then the sleeve35 is permitted to.-fall or drop by slacking the flexible line, and such falling or longitudinal movement of, the sleeve 35 relativeto the rod 36 eilects a gradually increasing rotational movement of the sleeve 35 due to the guiding, action; of the shaped slot 33 moving relative to, the pin 37. Since the slot 38' is preferably gradually increased in. its. inclination, the sleeve 35 has a considerable rotary force as it reaches its lower end of the, travel with respect to; the rod: 36, and while such, sleeve- 35. is. rotating, the hammer surface 35a contacts the anvil surface 41a of the anvil ring 41 to impart a rotary, jarring: impact-lin a left-hand or counterclockwise direction (as; viewed from the top. of Figure 1.)- to the anvil ring 41.. Thus, thesurfaceSSa acts as. a hammer which imparts the rotary impact to the anvil ring 41 and since the anvil 41 is connected to'the body 40; and the-body 40 is connected tothe latch arms 42; which are engaged in the longitudinal slots 15c, the rotation of the anvil ring 41 effects a turning or rotation of the valve member 1-5. One lowering of the sleeve 35' withrespect tothe rod 36 is generally insufii cient to turn the valve member 15 from the open to the closed position, so that the sleeve 35' is ordinarily raised and lowered several times in order to completely move the valve member 15* to its closed position (Figure 7);. Itshould benoted that, as the sleeve 35 islowered rela- The retracting lugs 6 tive tothe rod 36; the rod 36 isprevented from turning to the right or clockwise by reason of frictional resistance provided by the contact between the external surface of the valve member 15 and the internalsurfaceor bore wall of the housing 10, or by any other-suitable'frictionresistant means. I

As the valve member 1 5- is thusbeing; rotated by the reciprocation of the outer'sl'eeve 35" with respect to the rod 36, the cam lugs 25 are moved from the low points 265 of the cam surfacetoward the high points 26ironthe cam ring 26. As the camlugs 25- thuscooperate with the cam surface on the cam ring 26, the-valve member 15 is urged longitudinally or upwardly E asufiicientamount to tightly wedge the valve member 15 in sealing contact with the inner tapered surface 10b of the valve housing 10. Also, during such rotation of thevalve member 15, the latch dogs 42b-are moved relative to the retracting lugs and, just before the pin 33'- contacts the end of the slot 32, the dogs 42b engage the-inner surfaces 75a of the retracting lugs 75 to urge the latch arms 42 inwardly and release same from their connected position in the longitudinal" slots 150. The retracting lugs therefore serve as a stop means to 'pr'event further rotation ofthe valve member 15- with the; actuating or jarring tool A illustrated in Figures 17-, but primarily the retraction of the latch arms 47/ by the lugs 75 serves to indicateat the surface of the well" when the valve is closed because when the arms 42- are retracted', the tool A drops and an increased weight on the flexible support lineis indicatedat the surface of thewell. V

In Figure 8 of the drawings, a modified formof the actuating or jarring tool A is illustrated, and such modified tool is identified by theletter A; Allof theparts of the modified tool' A" are identical withthat illustrated in Figure 1 for the tool A, except that the parts are reversed so that instead of imparting a left-hand or counterclockwise rotational movement (as-viewed from top of Figure 1') to the valve member'IS as with'the tool A, a right-hand or clockwise rotational movement isinrparted withthe modified tool A" so*-that thetool A is adapted" to move the valve element 15 from the closed position to the open position. The latch arms 42 and the structure for mounting'same at thelower end of the tool A of Figs. 1-7' would obviously'be located at the lower end of thetool A shownin Fig.7 8. Pref erably, the dogs 42b on. the latch arms 42 'shown in the tool A ofi' Figures 17 are omitted from the tool A so that the retracting lugs 75 do not interfere with; the em gagementof the latchingarms 42 in the longitudinal'slots 15's of' the valve member 15'. All parts of the tool" A which are similar oridentical to the parts ofthe tool A have the same identifying numerals followed by a prime mark.

The operation of the modified tool A ofFi'gure 8} is the same as that shown in Figures '1-7, except that the rotation is in a different direction as above explained. Such modified tool A would also be suspended from a cable or-other flexible support and manipulated thereby.

It should: be pointed out that in the closing of the valve member 15 by the use of the jarring tool A, the rotation of the valve element 15- with the tool A is limited by the co-action ofi'the retracting lugs 75 with the dogs 42b, and by reason of such construction and co-action, the stop pin 33- doesnot contact the extreme left' end" or limit of the slot: 32 (Figure 1). However, inthe event the valve does leak when it has been moved to the closed position and when thedogs 42b have contacted the retracting lugs 75* to. retract: the latch arms 42, the 'tool A can be removed from. the well tubing or pipe and latch arms similar to those illustrated. in-Eigure- 8 can besubstituted. for thelatch arms 42 in the tool. A so that the tool. is identical with that shownin Figure 1. except that the-dogs, 42b, are omitted. With such. a-, construction, the valve element or member 15 can be further moved 7 to the left or counterclockwise (as viewed from the top of Figure 1). and the cam lugs 25 will ride up further on the cam surface of the cam ring 25 so that a further tightening or wedging of the valve member 15 in the valve housing is effected' It should also be pointed out that in the opening of the valve by the movement of the valve element or member to the right or clockwise (as viewed from the top of Figures 1 and 8), the stop or limit of rotation of the valve member 15 is obtained by the contact of the stop pin 33 with the right end of the slot 32 (Figure 1).

In the usual use of the valve construction of this invention, a plurality of valves are positioned in the Well tubing or pipe and are longitudinally spaced with respect to each other. In other words, a duplicate valve assembly is positioned above or below the valve assembly illustrated in the drawings and the valves are both constructed for operation'or actuation by the jarring tools A and A. With the lock arrangement, including the lock ring 50, for retaining the latch arms 42 in the retracted position (Figure 2), the jarring tool A (or A) can be lowered through the bore of each of the valves positioned in the well pipe or tubing. Therefore, the jarring tool can be lowered to a particular valve which itis desired to actuate or operate, since the jarring tool A or A can be lowered to the predetermined elevation at which the particular valve to be actuated is located and then the sequence of operations, as explained above, for their connection and actuation of the jarring tool on the valve element 15 can be effected.

Although various instances wherein it is desirable to selectively operate a plurality of valves in a well pipe will occur to those skilled in the art, the invention is particularly suitable for use in the dual completion of oil and gas formations in a well (Fig. 9), wherein one valve V-l of the type described above in connection with Figs. 1-7 is positioned above a conventional well packer P and another valve V-2 of the same type is positioned below such packer P, with the upper valve V-l being adjacent a gas formation X and the lower valve V-Z being adjacent an oil formation Y. With such arrangement, the valves can be manipulated by the manipulation of the actuating tool A of this invention so as to open either or both of the valves or the actuating tool A can be used to close either or both of the valves at the desired times for effecting the various well operations such as washing of the mud from the well, acidizing, and the production of the oil through the tubing and the gas through the annulus in the well bore.

The foregoing disclosure and description of the invention is illustrative and explanatory thereof and various changes in the size, shape and material, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
