Abstract
Abstract A powered coupling device for connecting massive tubular bodies, particularly at locations remote from the center of operations, as in connecting large diameter conduit or pipe to a subsea wellhead. The coupling device includes a pin member sealingly received in a box or socket member and power-driven latch elements for strongly securing the pin-and-box members together and to afford a metal-to-metal seal between the members to supplement a plastic seal between the members.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A powered coupling device, comprising; a. a tubular box member having a cylindrical socket terminating in a conically tapered seat at its inner end; b. a tubular pin member slidably receivable in said box member and having a conically tapered end face abuttable against said seat; c. an annular latching groove in the exterior of said pin member spaced from said end face; d. latching dogs mounted to the outer end of said socket for radial movement into and out of latching engagement with said latching groove; e. a latching collar surrounding said latching dogs and having threaded connection to the exterior of said socket for longitudinal movement relative thereto in response to rotation of said collar relative to the socket; f. wedge means carried by said collar cooperating with said latching dogs to urge the latter radially inwardly in response to relative upward movement of said collar and to release said latching dogs for outward radial movement in response to relative downward movement of said latching collar; g. fluid pressure-operated power means mounted on said box member; and h. rotary drive means connecting said power means to said latching collar.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
25 words
A powered coupling device according to claim 1 including an annular plastic seal element disposed in said box member for sealing about said pin member.
Claim 4
Dependent Claim
38 words
A powered coupling device according to claim 1 including means for mounting said latching dogs to the outer end of said socket comprising oppositely extending overlapping lip elements on said dogs and said outer end of said socket.
Claim 5
Dependent Claim
32 words
A powered coupling device according to claim 1 wherein said wedge means includes a ring mounted for relative rotation in said collar and having a wedging surface for engaging said latching dogs.
Claim 6
Dependent Claim
19 words
A powered coupling device according to claim 4 having antifriction bearing means disposed between said ring and said collar.
Claim 7
Dependent Claim
62 words
A powered coupling device according to claim 1 wherein said rotary drive means includes: a. spur gears driven by said power means; and b. an internally toothed ring gear mounted on said latching collar for rotation about an axis parallel to those of said spur gears and having its teeth in longitudinally slidable meshing engagement with the teeth of said spur gears.
