Abstract
Abstract A joint for securing tubular pin and box sections together, including a locking member (35) carried by the box section and tightenable laterally against the pin section by an actuating element (48) which is connected threadedly to the box section and is rotatable by a rotary driving part (63) adapted to be turned by a tool (74), with the joint including holding means for releasably retaining the driving part (63) against rotation. The driving part (63) is preferably mounted for movement relative to the actuating element (48) between a locking position in which the driving part (63) is retained against rotation and a released position in which the driving part (63) can be turned to adjust the actuating element (48). The actuating element (48) desirably contains a non-circular recess within which a correspondingly non-circular portion of the driving part (63) is received to transmit rotation between the parts. A fastener (51) for securing the actuating element (48) rotatably to the locking member (35) can be detached from the locking member (35) by a tool extending through an opening in the driving part (63) and through a spring (68) which yieldingly urges the driving part (63) to its locking position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
138 words
A joint comprising a box section, a pin section, a locking member mounted to the box section for actuation toward and away from the pin section, an actuating element connected threadedly to the box section and operable by rotation about an axis to actuate the locking member inwardly against the pin section to a position retaining the sections together, a rotary driving part adapted to be turned about said axis by a tool and engageable with the actuating element to rotate it, and holding means retaining said driving part against rotation, characterized by said driving part being movable relative to said actuating element between a locking position in which the driving part is retained by said holding means against rotation, and a released position in which the driving part is free for rotation to turn said actuating element.
Claim 2
Dependent Claim
138 words
A joint comprising a box section, a pin section, a locking member mounted to the box section for actuation toward and away from the pin section, an actuating element connected threadedly to the box section and operable by rotation about an axis to actuate the locking member inwardly against the pin section to a position retaining the sections together, a rotary driving part adapted to be turned about said axis by a tool and engageable with the actuating element to rotate it, and holding means retaining said driving part against rotation, characterized by said driving part being movable relative to said actuating element between a locking position in which the driving part is retained by said holding means against rotation, and a released position in which the driving part is free for rotation to turn said actuating element.
Claim 3
Dependent Claim
36 words
A joint as claimed in claim 1, in which said driving part has an externally non-circular portion engaging an internally non-circular portion of said actuating element to transmit rotary motion thereto in different relative axial positions.
Claim 4
Dependent Claim
56 words
A joint as claimed in claim 1 or claim 2, in which said holding means include a flange outwardly of said driving part engageable by the driving part to retain it against rotation, said driving part being movable inwardly toward said box section relative to said actuating element and said flange and to said released position.
Claim 5
Dependent Claim
32 words
A joint as claimed in claim 3, including a tubular insert carrying said flange and having external threads connected to said box section and internal threads engaging threads on said actuating element.
Claim 6
Dependent Claim
30 words
A joint as claimed in any of the preceding claims, including means yieldingly resisting movement of said driving part relative to said actuating element between said locking and released positions.
Claim 7
Dependent Claim
70 words
A joint as claimed in any of claims 1 to 4, including a fastener for connecting said actuating element rotatably to said locking member, and a spring yieldingly urging said driving part to said locking position thereof, said holding means and said actuating element and driving part and spring being open to extension of a tool therethrough into engagement with said fastener to remove the fastener from the locking member.
Claim 8
Dependent Claim
116 words
A joint comprising a box section, a pin section, a locking member mounted to the box section for actuation toward and away from the pin section, an actuating element connected threadedly to the box section and operable by rotation about an axis to actuate said locking member inwardly against the pin section to a position retaining the sections together, a rotary drive part for turning the actuating element about said axis and adapted to be turned about said axis by a tool, and holding means for releasably retaining said drive part against rotation; characterized by said drive part having an externally non-circular portion within a non-circular recess in said actuating element to turn the actuating element.
Claim 9
Dependent Claim
116 words
A joint comprising a box section, a pin section, a locking member mounted to the box section for actuation toward and away from the pin section, an actuating element connected threadedly to the box section and operable by rotation about an axis to actuate said locking member inwardly against the pin section to a position retaining the sections together, a rotary drive part for turning the actuating element about said axis and adapted to be turned about said axis by a tool, and holding means for releasably retaining said drive part against rotation; characterized by said drive part having an externally non-circular portion within a non-circular recess in said actuating element to turn the actuating element.
Claim 10
Dependent Claim
52 words
A joint as claimed in claim 7, in which said drive part is movable along said axis relative to said actuating element between a locking position in which it is retained by said holding means against rotation and a released position permitting rotation of the drive part to turn the actuating element.
Claim 11
Dependent Claim
123 words
A joint comprising a box section, a pin section, a locking member mounted to the box section for actuation toward and away from the pin section, an actuating element connected threadedly to the box section and operable by rotation about an axis to actuate the locking member inwardly against the pin section to a position retaining the sections together, a fastener rotatably connecting said actuating element to said locking member, a drive part adapted to be turned about said axis by a tool and acting to turn the actuating element, characterized by said drive part being located laterally outwardly beyond said fastener and containing an opening through which a tool can extend inwardly beyond the drive part to engage and remove the fastener.
