Abstract: An axle shaft has radially outwardly extending drive fingers which drivingly engage drive slots in a wheel hub cover. The hub cover is rigidly secured to a wheel hub and maintains the axial position of the axle shaft. A shock absorber may be positioned between the drive fingers and the drive slots. The axle shaft may be formed from a hollow tube or a solid shaft by cutting an end portion of the shaft and deforming a cut section radially outwardly to form a drive finger.

Abstract: An axle shaft has an inboard end portion with a spline for engagement with a differential assembly and an outboard end with a flange for mounting a wheel hub assembly. One or both of the end portions have cavities for weight reduction. The inboard end portion cavity extends underneath the spline. The outboard end portion cavity extends completely underneath the flange.

Abstract: An axle assembly includes an axle in frictional driving engagement with a wheel hub. A torque limiting assembly limits the amount of torque that can be transmitted between the axle and hub. The torque limiting assembly includes an arm or rod, such as the shaft of a bolt, which biases the axle and hub together to provide a predetermined slipping torque. The rod or arm is housed in a clamp which extends axially over the outer peripheries of an axle flange and a hub flange.

Abstract: A closure comprises a hub with a central opening and a head pivotally connected to the hub, the head sealing the central opening when in a closed position. A lip seal relief is defined by a stepped surface between the head and the hub so that when the head is closed, the relief or clearance is provided between the head and hub inhibiting damage to a seal.

Abstract: A closure comprises a hub with a central opening and a head positionable within the hub, the head sealing the central opening when in a closed position, a spool rotatable about a post extending from the head, wherein rotation of the spool causes axial movement of the spool along the post, a plurality of radial arms extending from the spool to a plurality of locking segments.

Abstract: An actuated breach lock, comprises a hub for positioning on a pressurizable vessel, the hub being generally circular and having a central opening, a bearing surface disposed within the central opening, a head hingedly connected to the hub and having a shape which complements the central opening and which is received within the central opening, the hub having a plurality of teeth extending radially inward and separated by a plurality of gaps, a locking ring rotatably positioned on the head, the locking ring having a plurality of ring teeth separated by a plurality of ring gaps, each of the teeth having a circumferential length less than a circumferential length of the gaps in the hub, the bearing surface of the hub having an angle and the head having a bearing surface at the angle, the locking ring having a polygonal cross-section including two sides which engage the bearing surfaces respectively, the locking ring engaged by head and hub when the head is in a closed position, the closed position creating a lin

Abstract: A closure (100) having a hub (102) and pivotally connected head (104). The head is locked in a closed position within the hub by a locking ring (106). The locking ring is polygonal in shape and includes a substantially cylindrical surface and a conical surface. The device further includes a pressure warning device (126) which has a secondary function as a locking mechanism inhibiting unintentional opening of the head when the system is pressurized.

Abstract: A pressure retaining closure assembly has a door hingedly mounted to a pipe, vessel, or hub extending therefrom with an arcuate locking ring movably retained proximate an outer perimeter surface thereof. The locking ring is suitable to contract out of a groove in an opening in the pipe, vessel, or hub extending therefrom into an unlocking position and is suitable to expand wherein an outer portion of the locking ring extends into the groove in the opening in the pipe, vessel, or hub extending therefrom into a locking orientation. A locking ring actuator is provided having cylinder with a piston therein. The piston has a rod extending axially therefrom with a portion extending beyond the cylinder. Optionally, a bracket is mounted to the portion of the piston rod extending beyond the cylinder and a bracket is mounted proximate the bottom of the cylinder.

Abstract: A pressure closure having a round door with an arcuate locking ring having a plurality of arcuate locking ring segments connected by at least one connecting ring movably retained therewith proximate an outer circumference of an outer surface of the door. The locking ring segments may have at least one cavity extending through the arcuate length thereof. An arcuate connecting ring extends through each cavity in the locking ring segments retaining them together to form the locking ring. Alternatively, the connecting ring connects the locking ring segments together with connecting ring retaining links cooperating with the connecting ring and locking ring segments. Optionally, the cross-sectional configuration of the connecting ring is rounded. Advantageously, the optional at least one cavity extending through the locking ring segments has an axial opening extending the arcuate length of each locking ring segment.
