2 and other applications.
3 Referring now to the drawings, the reference
4 numeral 10 generally indicates a first tubular meT~er such as the top of a wellhead having one or more annular locking 6 notches 12 on its exteriox to which a second member of 7 connector, generally indicated by the reference numeral 1~, 8 is connected or disconnected.
9 The connector 14 includes.a tubular body 16 having an annular cavity 18 therein. The body 16 is adapted to 11 telescope over and seat and seal on member 10.
12 one ar more double acting piston and cylinder 13 assemblies 20 axe provided in the body 16 each with a 14 piston 21 having a piston rod 22 extending into the cavity lS 18. Hydraulic pressure line 24 supplies hydraulic pressure 16 to on~ side of.the pistons 21, and hydxaulic pressure line 17 26 ap~lies hydraulic pressure to the other side of the 18 pistons 21. An annular carriage 30 is.longitudinally movable 19 in the cavity 18 and is connected to the piston rods 22 and ~ longitudinally reciprocates with the pistons 21. The car-21 riage 20 bears against the inside of the body .16 for providing 22 a secure supportO
23 A plurality of locking dogs 32 are provided having 24 one end for engaging the locking notches 12 on the first member 10 and having their second ends extending through 26 seals into the body cavit~ 18. The dogs 32 move transversely 27 in the body 16 for engagement and,disengagement with the 28 locking notch 12.
29 A toggle linkage 3~ is provided to translate the longitudinal motion of each of the piston rods 22 into a 31 txansverse movement o~ one of the locking dogs 32. Each 32 toggle linkage 34 has a first pivot connection connected to ~4 _~_ '~'L~984 1 one of the dogs 32 within the cavity 1~. The first pivot connection may include a pin 36 as well as arcuatc power-3 bearing surfaces 38. The second pivot connection of each of 4 the toqgle linkages 34 is longitudinally actuated by the pistons 21 whereby the longitudinal movement of the second 6 pivot connections transversely moves the locking dogs 12.
7 The second pivot connections may include a pin 40 and coacking 8 arcuate power-bearing surfaces 42 between the linkage 34 and 9 a bearing journal 44, which rest on and is carried by the carriage 30.
11 An annular load spring 46 is supported on the 12 carriage 30 and acts against the second pivot connections 13 and toward the first pivot connections for locking the second 14 pivot connections in a past dead center position relative to the first pivot connections. The annular spring ring 46 is 16 retained to the carriage 30 by a retainer place 48 and hold-17 down bolts 50 although the spring 46 and bearing journals 44 18 are transversely movable on the caxriage 30 so that the 19 spring 46, which acts as a large garter spring, flexes outwardly and inwardly to allow the toggle linkages 34 to 21 snap over dead center into a locked or unlocked position.
22 The cavity 18 includes seals for sealingly en-23 closing the cavity whereby it may be filled with oil to 24 reduce maintenance of the operating parts and protect the ~5 operating parts from hostile subsea environment. A flexible 26 member such as a rubber bladder 52 may be provided which has 27 one side exposed to thé in~erior of the cavity 18 and a 28 second cide exposed to the exterior of the body 16 for ~9 compensating or a difference in fluid pressure between the 3~ cavity 18 and the outside of the body 16 as well as com-31 pensating for the movements of the piston rods 22 and dogs 1 32 into and out of the cavity 18.
2 Referring to Figure 2 with the second member 1~ in 3 position encompassing the first member 10 and in the unlocked 4 position, hydraulic fluid is applied to the bottom side of the piston 21 through line 26 which forces the piston rods 6 22 and carriage 30 upwardly. The second pivot connections 7 comprising the hearing journals 44 and pins 42 are ~rapped 8 between the carriage 30 and annular load ring 46. As the 9 second pivot connections move upwardly or longitudinally, they force the toggle linkages 34 to rotate about the first 11 pivot connections which includes the arcuate bearing surfaces 1? 38 and pins 36 to transversely move the locking dogs 32 into 13 the lockihg notches 12 of the first member 10. Furthermore, 14 as the angle between the centerline of the toggle linkages 34 and the centerline of the doys 32 decreases, the ratio of 16 the radial inward force on the dogs 32 to the vertical 17 actuating force on the carriage 30 increases. This mechanical 1~ advantage allows a high clamping force with relatively low 19 actuating forces. Furthermore, the load ring 46 flexes radially outward to allow the linkage 34 to snap over dead 21 center and then inwardly as the annular ring 46 bottoms out 22 against the body 16 to cre~te a positive past dead center 23 lock to hold the dogs 32 in engagement, as shown in Figure 24 1.
To unlock the connector 14, hydraulic pressure is 26 applied through line 24 moving the pistons 21, piston rods 27 22~ and carriage 30 downwardly. ~he xet~iner plates 48 28 carry the load ring 46 and force the second pivo~ connections 29 . including the bearing journals 44 to move downwardly over dead center relative to the first pivot connections to 31 unlock the connector 14. Further downward movement of the 32 carriage 30 causes retraction of the dogs 32 by the pins 36 33 ana 42.
l The presen~ invention, therefore, is ~ell adapted 2 to carry out the objec~s and at~ain the ends and advantages 3 mentioned as well as others inherent therein. While a 4 presently preferred embodiment of the invention has been given for the purpose of disclosure, numerous changes in the 6 details of construction and arrangement of parts may be 7 provided, without departing from the spirit of the invention 8 and the scope of the appended claims.

9 The connector 14 includes.a tubular body 16 having an annular cavity 18 therein. The body 16 is adapted to 11 telescope over and seat and seal on member 10.
12 one ar more double acting piston and cylinder 13 assemblies 20 axe provided in the body 16 each with a 14 piston 21 having a piston rod 22 extending into the cavity lS 18. Hydraulic pressure line 24 supplies hydraulic pressure 16 to on~ side of.the pistons 21, and hydxaulic pressure line 17 26 ap~lies hydraulic pressure to the other side of the 18 pistons 21. An annular carriage 30 is.longitudinally movable 19 in the cavity 18 and is connected to the piston rods 22 and ~ longitudinally reciprocates with the pistons 21. The car-21 riage 20 bears against the inside of the body .16 for providing 22 a secure supportO
23 A plurality of locking dogs 32 are provided having 24 one end for engaging the locking notches 12 on the first member 10 and having their second ends extending through 26 seals into the body cavit~ 18. The dogs 32 move transversely 27 in the body 16 for engagement and,disengagement with the 28 locking notch 12.
29 A toggle linkage 3~ is provided to translate the longitudinal motion of each of the piston rods 22 into a 31 txansverse movement o~ one of the locking dogs 32. Each 32 toggle linkage 34 has a first pivot connection connected to ~4 _~_ '~'L~984 1 one of the dogs 32 within the cavity 1~. The first pivot connection may include a pin 36 as well as arcuatc power-3 bearing surfaces 38. The second pivot connection of each of 4 the toqgle linkages 34 is longitudinally actuated by the pistons 21 whereby the longitudinal movement of the second 6 pivot connections transversely moves the locking dogs 12.
7 The second pivot connections may include a pin 40 and coacking 8 arcuate power-bearing surfaces 42 between the linkage 34 and 9 a bearing journal 44, which rest on and is carried by the carriage 30.
11 An annular load spring 46 is supported on the 12 carriage 30 and acts against the second pivot connections 13 and toward the first pivot connections for locking the second 14 pivot connections in a past dead center position relative to the first pivot connections. The annular spring ring 46 is 16 retained to the carriage 30 by a retainer place 48 and hold-17 down bolts 50 although the spring 46 and bearing journals 44 18 are transversely movable on the caxriage 30 so that the 19 spring 46, which acts as a large garter spring, flexes outwardly and inwardly to allow the toggle linkages 34 to 21 snap over dead center into a locked or unlocked position.
22 The cavity 18 includes seals for sealingly en-23 closing the cavity whereby it may be filled with oil to 24 reduce maintenance of the operating parts and protect the ~5 operating parts from hostile subsea environment. A flexible 26 member such as a rubber bladder 52 may be provided which has 27 one side exposed to thé in~erior of the cavity 18 and a 28 second cide exposed to the exterior of the body 16 for ~9 compensating or a difference in fluid pressure between the 3~ cavity 18 and the outside of the body 16 as well as com-31 pensating for the movements of the piston rods 22 and dogs 1 32 into and out of the cavity 18.
2 Referring to Figure 2 with the second member 1~ in 3 position encompassing the first member 10 and in the unlocked 4 position, hydraulic fluid is applied to the bottom side of the piston 21 through line 26 which forces the piston rods 6 22 and carriage 30 upwardly. The second pivot connections 7 comprising the hearing journals 44 and pins 42 are ~rapped 8 between the carriage 30 and annular load ring 46. As the 9 second pivot connections move upwardly or longitudinally, they force the toggle linkages 34 to rotate about the first 11 pivot connections which includes the arcuate bearing surfaces 1? 38 and pins 36 to transversely move the locking dogs 32 into 13 the lockihg notches 12 of the first member 10. Furthermore, 14 as the angle between the centerline of the toggle linkages 34 and the centerline of the doys 32 decreases, the ratio of 16 the radial inward force on the dogs 32 to the vertical 17 actuating force on the carriage 30 increases. This mechanical 1~ advantage allows a high clamping force with relatively low 19 actuating forces. Furthermore, the load ring 46 flexes radially outward to allow the linkage 34 to snap over dead 21 center and then inwardly as the annular ring 46 bottoms out 22 against the body 16 to cre~te a positive past dead center 23 lock to hold the dogs 32 in engagement, as shown in Figure 24 1.
To unlock the connector 14, hydraulic pressure is 26 applied through line 24 moving the pistons 21, piston rods 27 22~ and carriage 30 downwardly. ~he xet~iner plates 48 28 carry the load ring 46 and force the second pivo~ connections 29 . including the bearing journals 44 to move downwardly over dead center relative to the first pivot connections to 31 unlock the connector 14. Further downward movement of the 32 carriage 30 causes retraction of the dogs 32 by the pins 36 33 ana 42.
l The presen~ invention, therefore, is ~ell adapted 2 to carry out the objec~s and at~ain the ends and advantages 3 mentioned as well as others inherent therein. While a 4 presently preferred embodiment of the invention has been given for the purpose of disclosure, numerous changes in the 6 details of construction and arrangement of parts may be 7 provided, without departing from the spirit of the invention 8 and the scope of the appended claims.
