  • Ball joint link and method of producing same
    Patent number: 5609433
    Abstract: A ball joint link includes a ball stud, a ball cap and a strengthening element that are all insert molded in a thermoplastic body. The strengthening element is disposed around the ball stud and includes a first portion which receives the ball of the ball stud and a second portion which receives the stud of the ball stud. The strengthening element is securely anchored in the body, and the second portion of the strengthening element resists pull out forces tending to remove the ball stud from the ball joint link. The ball cap snaps in place on the ball and is substantially completely embedded within the body. Insert molding methods for forming the ball joint link are disclosed.

  • Ball joint assembly
    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.

  • Insulator structure and method of construction
    Patent number: 5406033
    Abstract: A composite link and insulator, and method of construction, includes a fiberglass body. The body is formed by coating glass fibers with a liquid resin and winding the fibers around a plurality of tubular fittings or bushings in two layers, a first extending longitudinally of the body and the second transversely and around the first. A polymer shield layer and weathersheds are injection molded over the fiberglass body to create an insulator. The insulator may also be provided with stiffening plastic inserts at either end for increasing strength without adding significantly to the insulator's overall weight.
