- FIG. 1 Shown secured to the wellhead 10 is a connector apparatus according to the present invention and designated generally by the reference character 20.
- An identical duplicate connector apparatus 22 is also shown connected to the wellhead and which may serve in a stand-by capacity if desired should the first connector apparatus become inoperative for any reason.
- the functions of the wellhead 10 are controlled remotely by a water surface vessel 24 via an umbilical 26 connecting with the riser 16 of the wellhead.
- the umbilical 26 provides fluid communication between the vessel 24 and the wellhead 10 to in turn impart fluid to the connectors 20 and 22 as will be described hereinafter.
- umbilicals 28 and 30 may be provided for direct fluid communication between the vessel 20 and the connectors 22 and 20 respectively in accordance with a further embodiment of the invention as will be explained.

- the male stinger member 48 is provided with an outwardly projecting flange 50 which is fixedly secured such as by means of bolts 52 (only one bolt being shown in FIG. 2) to the riser plate 12 which is a part of the upper detachable portion 16 of the wellhead 10 (see FIG. 1).
- bolts 52 only one bolt being shown in FIG. 2
- the engaging surface 54 of the male stinger 48 and the engaging surface 56 of the female receptacle 32 both taper downwardly and inwardly as shown in the drawmg.
- valve block 58 Secured by any suitable means such as bolts and the like to the male stinger 48 is a valve block 58 which receives appropriate fluid supply lines from the umbilical 30.
- the fluid supply lines connect with the valve block 58 and are in fluid communication with a plurality of passageways illustrated with reference characters 60 and 62 in FIG. 2.

- the male stinger member 118 in the embodiment of FIG. 3 is not itself attached to the upper detachable portion or riser 16 of the wellhead 10. Rather the male stinger 118 is inserted into the annular second female receptacle 1 14 so that the second female receptacle releasably engages between the first female receptacle 100 and the male stinger 118.
- the annular second female receptacle 114 has sidewalls that taper downwardly and inwardly to mate with similar such sidewalls of the stinger 118 and the first female receptacle 100.
- the male stinger 118 is of unitary construction and includes a valve block 120 formed integrally thereof although it will be appreciated that the valve block 120 may be formed separatedly and then attached to the male stinger 118.
- the male stinger 118, the annular second female receptacle 114 and the first female receptacle 100 taper downwardly and inwardly as described with respect to the embodiment of FIG. 2.
- passageways are provided in the foregoing members similar to those described with respect to FIG. 2.
- the male stinger includes at least one passageway such as that designated by the reference character 122, one end of which mates for fluid communication with a corresponding passageway 122a in the annular second female receptacle 114 to in turn mate for fluid communication with a corresponding passageway l22b in the first female receptacle 100.
- Annular seal means are provided around the passageways at their mating ends for purposes of forming a liquid-tight seal between the ends of the passageways as described with respect to FIG. 2. Consequently, the passageways provide fluid communication between the umbilical 30 and fluid supply lines 122(- (similar to lines 6012 and 62b in FIG. 1) which pass to the stack portion 18 of the wellhead for purposes of controlling the functions thereof. In addition, while not shown in FIG. 3, certain of the passageways may communicate with fluid supply lines to control functions of the riser portion 16 of the wellhead as desired.
- the male stinger 118 is locked to the annular second female receptacle 114.
- the preferred apparatus for performing the interlocking function is that shown in the previously mentioned US. Pat. No. 3,486,556 to which reference is made for a full and complete disclosure of a thru-center latching means. However, a brief description of the latching means applied to the present embodiment will be given.
- a rod 124 is provided which extends through the male stinger 118 and connects to the latching means at its lowermost end.
- a generally U-shaped element 126 is connected at the uppermost end of the rod 124 and serves as an attaching means for a raising and lowering cable (not shown).
- a piston 128 is fixedly secured near the lower end of the rod 124 and is slidable within a cylinder 130 provided with suitable seals so as to contain a fluid.
- a flat portion 132 Located on the lowermost end of the rod 124 is a flat portion 132 through which a pin 134 extends, the pin having a central pivotal axis.
- Actuating links 136 are pivotally connected to the pin 134.
- levers 138 At the outermost ends of the links 136 are levers 138 which are connected by means of the pins 140 which in turn have central pivotal axes.
- the levers 138 are pivotally attached to the stinger 118 by means of pins 142.
- a stop 144 is located in the foremost or nose portion of the stinger portion 118.
- Interlocking shoulders 146 are formed as part of the annular second female receptacle 114 being of a larger diameter than the lowermost portion of the first female receptacle 114.
- Load bearing shoulders 148 are located on each lever 138 to engage mating shoulders of a similar configuration on each of the links 136. In like manner, load bearing shoulders or surfaces 150 and 152 are located on the links themselves. While not visible in the drawings, openings in the levers 138 for the pins 140 are dimensioned significantly larger in diameter than the diameter of the pins 140. In this manner, a loose fit is achieved at these pivot points. In like manner, the opening through the link 136 as viewed in FIG. 3 to accommodate the pin 132 is dimensioned larger than the pin 132.
- the fluid control functions of the embodiments are similar to those described with respect to the embodiment of FIG. 2 and reference is hereby made to the description of operation of that embodiment.
- the female receptacle 100 is secured to the stack plate 14 by means of spring mounting means for flexing attachment as described.
- the annular second female receptacle 114 is secured to the riser plate 12 and the male stinger member 118 is inserted into the second female receptacle 114, all as shown in FIG. 3.
- the latching and interlocking means functions as described in U.S. Pat.
- the load bearing surfaces 148 on the levers 138 and the load bearing surfaces 150 and 152 of the links 136 are in their respective mating engagement relationship when the levers 138 engage the shoulder 146 so that any load transmitted to the levers 138 from the shoulder 146 is borne by the load bearing surfaces rather than the pins or axis members 134 and 140, all as described in US. Pat. No. 3,486,556.
- the apparatus of FIG. 3 provides an expedient means for separating all control lines from the wellhead.
- the latching means associated with the rod 124 are actuated as previously described herein so that the levers 138 are released from the interlocking shoulder 146.
- a cable attached to the rod 124 can be raised taking with it the male stinger 118 and its associated parts.
- the riser portion 16 is lowered such as by means of a cable or umbilical 26 back to the wellhead site. While the riser 16 is guided into engagement with the stack portion 18 of the wellhead 10, at the same time the second annular female receptacle 114 is guided into engagement with the first female receptacle 100.
- the annular second female receptacle 114 is automatically seated in engagement with the female receptacle 100. Fluid communication is then established through the passageways and wellhead functions may be carried out.
- the male stinger 118 is lowered such as by cable attached to the upper end 126 of the rod 24 until the male stinger engages the annular second female receptacle 114. Then the male stinger 118 is guided into a sealed, seated position by rotating the male stinger portion 118 until a lug engages a recess 162 to properly align fluid passageways within the male stinger 18 with corresponding passageways in the annular second female receptacle 114. Once this position is attained, fluid communication may be established via the passageways and functions of the well head 10 begun.
