A clamp for securing an item includes a locking rod, first and second clamping members, and a retainer. The locking rod includes an elongated body and a locking member connected to a first end of the elongated body. The locking member is movable between a clamping position and a release position. The first clamping member includes a first opening for receiving a second end of the locking rod body therethrough. The second clamping member is adapted to align with the first clamping member to receive the item therebetween. The retainer is connected to the second clamping member and includes a second opening for receiving the second end of the locking rod body and an interlocking feature for engaging a corresponding interlocking feature on the locking rod body when the locking rod body is in a first rotational position. When the item is positioned between the first and second clamping members and the locking rod is inserted through the first opening and into the second opening and oriented in the first rotational position, moving the locking member from the release position to the clamping position tightens the first and second clamping members into clamping engagement with the item.

A coupling device having a first member provided with threads, a second member having an opening into and out of which the first member is inserted and removed, threaded elements within the second member mounted for movement between a first position where the first member may be threaded with the second member and a second position where the threaded elements have a diameter larger than the diameter of the threads of the first member permitting the first member to slide axially in and out of the second member, pull/lock/torque pins associated with the threaded elements and a manually operable mechanism for moving the threaded elements longitudinally into engagement with the pins expanding the threaded elements to their second position. The second member including an outer body provided with oval openings through which the pull/lock/torque pins pass and the threaded elements may include oval indentations against which the ends of the pull/lock pins abut, and wherein the threaded elements may include shoulders against which the pull/lock/torque pins abut.

A reaction nut for location on a threaded bolt, particularly a bolt to be nsioned by a hydraulic tensioning device, includes a plurality of internally-threaded segments (22) movable between an outer-most inoperative position radially spaced from the bolt (2) and an operative position making threaded engagement with the bolt (2). The segments (22) have tapering surfaces thereon. A primary ring member (16) is movable axially relative to the segments (22) and has a corresponding tapering surface (18) thereon. A first resilient device (20) biases the tapering surface (18) of the primary ring member (16) into engagement with the tapering surfaces on the segments (22). A cam then (26) moves the primary ring member (16) from a rest position to an axially displaced position against the bias of the first resilient device (20) whereby the segments (22) are moved by an associated second resilient device (24) between their operative and inoperative positions.

A tapered split nut with depressed by coil spring downward in a central hole of a outer cylinder body is installed so as it can move upward. A hanging bolt is inserted from the bottom while it is pushing said split nut up. Owing to the upward movement of the hanging bolt, the split nut moves downward due to a pushing movement with pressure by the coil spring, and the split nut engages with and bit the thread portion of the hanging bolt.

A threaded fastener has a casing enclosing at least three radially inwardly biased arcuate segments positioned to engage the threads of a bolt or hollow threaded member. The casing defines spaced apart internal frustoconical surfaces positioned to engage corresponding surfaces of the segments in the same axial direction. The radially inner ends of the frustoconical surfaces are directed toward a first end of the fastener, and the diameter of the radially inner end of the frustoconical surface away from the first end of the fastener is less than the radially outer diameter of the other frustoconical surface. The threads of the segments substantially fully engage the threads of the bolt or hollow threaded member.

An improved slide-fit nut is provided for rapid push-on mounting to a substantially seated position on a threaded bolt or the like. The slide-fit nut includes a plurality of threaded nut segments carried within a nut housing and adapted for radial expansion to accommodate push-on mounting onto a threaded bolt. A cap plate on the nut housing includes cam members for retaining the nut segments in threaded engagement with the bolt upon rotation of the nut in a tightening direction. When the nut is rotated in an opposite direction, the cam members displace the nut segments in a radially outward direction relative to the bolt, resulting in substantial disengagement of the nut segments to permit rapid pull-off removal of the nut from the bolt.

A seal mechanism for joining two bracket members on a shipping container comprising a male member and a female member cooperating with said male member to prevent retrograde motion once the male member and female member are assembled. The female member includes locking means of different internal diameter cooperating with the male member to permit the male member to move in one direction, but precluding retrograde motion.

A wheel balancer having a threaded shaft with a free end for receiving a wheel to be balanced and a drive for rotating the shaft to a wheel secured thereon so as to enable the obtaining of data relative to imbalance of the wheel as the wheel rotates. A locating device is provided for engaging a wheel on the shaft to locate the wheel properly thereon and a nut is utilized in connection with the shaft for holding the wheel against the locating device. The nut includes apparatus for selectively moving the nut threads radially inwardly into engagement with the shaft threads and radially outwardly out of engagement with the shaft threads so that the nut may be rapidly advanced on or removed from the shaft without rotation when the nut threads are out of engagement with the shaft threads.

A quick connect coupler for a threaded bolt. The coupler includes a segmented core within its body having a threaded passageway to receive the bolt. The segments of the core spread apart when the bolt is inserted into the coupler and into the passageway. Then the segments of the core come together to grip the bolt and as the coupler is turned upon the bolt to tighten it, the core within the coupler body wedges against an inclined surface in the body to hold the segments together against a pull of the bolt.
