Abstract: A locknut comprising a metal nut including a threaded internal wall for engaging a threaded shaft; and a metal ring including an internal threaded wall defining a hole for engaging the threaded shaft. The ring comprised of a steel alloy. The threaded internal wall of the nut and the threaded internal wall of the ring being in general axial alignment when the ring is received by a bore of the nut. The ring has an elliptical configuration and is configured to distort to a circular configuration when the threaded shaft is engaged with the threaded internal wall of the nut and the threaded internal wall of the ring. The ring sized such that the stress in the ring when the ring is distorted to the generally circular configuration is less than the yield stress of the steel alloy. A thermal diffusion coating may be applied to the ring.

Abstract: An anti-rotation clip is adapted to be attached to a fastener or connector assembly to ensure the tightened threaded connection of the assembly. The anti-rotation clip in one embodiment of the invention includes one or more co-axial clips to radially and forcibly grip one or more hexagonal parts rotatable to a body, and a pair of tang members extending from one clip to engage a pair of grooves having flat bottoms on the body to prevent the hexagonal parts from rotation and the clip from axially moving away relative to the body. In another embodiment of the invention, two co-axially connected clips are adapted to radially and forcibly grip two connectors, having hexagonal exteriors, which are in a tightly threaded connection to a body and may be loosened in opposite rotary directions. The two clips lock the two connectors together to prevent the loosening of either one. An axially spaced apart tang member restrains a flange member on the body to prevent the clip from displacement from its axial position.

Abstract: A single lock nut washer formed of steel or other material to simultaneously lock an inner wheel bearing nut and an outer bearing nut secured to an axle spindle. An annular member has a plurality of outwardly extending tabs that bend over to engage the outer surface of the outer bearing nut to prevent rotation. An inwardly extending lug engages a groove in the axle spindle to prevent rotation of the washer. A plurality of circumferentially arranged bores are each adapted to receive a longitudinally extending pin of the inner bearing nut to prevent relative rotation. The lug is offset from the bores and is preferably oriented circumferentially intermediate one of the bores and a midpoint to an adjacent bore.

Abstract: The clamping and locking device (18) of the clamp includes a screw (22) arranged in a direction which is transverse with respect to the articulated elements of the clamp and engaged through two blocks (19, 19') bearing on two articulated elements of the clamp, which include two guide journals (20a, 20b) each engaged and held in an opening of a bar (26a, 26b). The openings (27a, 27b; 28a, 28b) include a pair (27a, 27b) of circular openings and a pair (28a, 28b) of oblong openings. Nuts (25, 25') allow the clamp to be clamped and locked. The clamp further includes a blocking device (31) consisting of a support (33) including a strut (34) traversed by an opening and including parts (35a, 35b) for engagement on the bars (26a, 26b), a lock nut (37) rotationally mounted in the opening of the support (33), an arrangement (41) for blocking the lock nut (37) in rotation and in axial translation, and at least one blocking finger (44a, 44b) pivotably mounted on the support (33).

Abstract: A load-bearing member is positioned in a slot extending through a composite structure of laminated reinforced plastic having overlapping layers of fabric plies embedded in a thermoplastic material. A connecting means such as a shank of a bolt connects the load-bearing member with a second structure. The load-bearing member has a flat surface engageable with a flat surface of the slot which is generally parallel with the edge surface of the composite structure in abutting relationship with a surface of the second structure. The slot extends through the overlapping layers of fabric plies in such a manner that the load is distributed by the load-bearing member to avoid the concentration of forces which cause shear failure and delamination.
