  • Patent number: 5551722
    Abstract: A vehicle suspension link or attachment includes prefabricated and assembled elements comprising a bolt or stud assembly and retainer elements on each end. The stud or bolt assembly is mounted between two suspension elements and secured by the retainer assemblies to provide a rigid, spaced, shock-absorbing connection between components of a vehicle suspension system. The invention is used in one form as a connecting link between the end of a stabilizer bar or anti-sway bar and the movable mounting arms of the vehicle's independent suspension system. The stud type suspension link includes a single spacer element or a pair of spaced-apart spacer elements which are integrally molded on the stud.

  • Patent number: 5503374
    Abstract: A self-adjusting shim includes an inner element and an outer element. The outer element defines an internal threaded bore and a projecting tab that limits rotation of the outer element. The inner element includes a threaded outer surface and an inner opening. The threaded outer surface is received in the threaded internal bore such that relative rotation between the inner and outer element results in relative axial movement therebetween. The inner opening includes a torque transmitting feature such as an out-of-round surface or an internally projecting element that is directed radially inwardly so as to couple the inner element to a bolt for rotation.

  • Patent number: 5492428
    Abstract: A ball joint assembly includes a ball stud and bearing sub-assembly that is economical to manufacture, strong, durable and long-lasting. The bearing is molded directly on the ball surface of the ball, thereby eliminating the need for precise tolerances in machining the ball. Microcavities formed on the ball surface facilitate the introduction of lubricant between the ball and the bearing. A two-piece stud and collar nut adds ease of manufacture.

  • Patent number: 5334056
    Abstract: An automatic cable connector includes a hammer that is moved to a cocked position by the end of an inserted cable. A hammer spring is compressed during the cocking motion. When the cocked position is reached, a frangible abutment fractures and the hammer is free to move independently of the cable. The spring drives the hammer into tapered gripping jaws with an impact that firmly grips the jaws onto the cable.

  • Patent number: 5226216
    Abstract: A clamp assembly with a releasable bail for securing and suspending cables, drop wires or the like that utilizes a locking structure cooperating with an aperture in a tail of the clamp assembly to secure and lock the releasable free end of the bail to the clamp assembly. Preferably, the locking structure is a foot segment and head at the end of a leg of the bail with a reduced portion permitting passage of the foot segment from an entry portion along a connecting portion to locate the head at a lock portion. Additionally, the other leg of the bail can be slideably attached utilizing an interlocking structure that reduces bail deformations during installation. Furthermore, the present invention provides a method for assembling the cable clamp assembly wherein the first and second legs are assembled and attached to the tail, and also providing a method for simultaneously forming the reduced portion of the second leg and a deformed region in the tail to capture the first leg in the tail.

  • Patent number: 4993902
    Abstract: A plastic capped lock nut includes a metal body having a threaded bore extending axially between transverse opposite end faces and includes an annular wall extending outwardly of one of the end faces to define an open ended cavity for receiving a resilient lock ring mounted in the cavity in coaxial alignment with the threaded bore. An end cap of plastic material including an annular side wall and an outer end engages the lock ring and is sonically welded thereto. The annular wall of the metal body is deflected inwardly tightly against the lock ring to secure the ring in the cavity against rotation relative to the body. The end cap provides protection for exposed threads of a threaded rod or other element extending outwardly of the bore of the lock nut body and ring.

  • Patent number: 4907924
    Abstract: A backward starting locknut comprises a polygonal-shaped metal nut having a threaded axial bore extending from a front end face normal thereto toward a recess formed in an opposite or backside of the nut body. A locking insert of resilient plastic material having a threaded bore aligned with that of the nut is seated in the recess and includes an annular, thick wall portion secured within the recess and an annular, thin wall portion integrally joined to the thick wall portion and extends outwardly from the recess and is provided with a threaded bore. The metal nut includes an annular wall section defining the recess and the wall section is deflected radially inwardly to compress the thick wall portion of the plastic insert and thereby constrict an inner portion of the threaded bore in order to establish a prevailing torque when a threaded rod is fully engaged in the bore of the insert.
