  • Publication number: 20150082671
    Abstract: A securing apparatus including a first and second component. The first component has an opening extending along an axis. The elongated member has a piston hole penetrating the first component and aligned with the opening. A piston is located within the piston hole, and is complimentary shaped to sit within the piston. A pressure member is located within the opening, and an activator is configured to coordinate with and extend into the opening. The activator applies a force to the pressure member and distorts the pressure member. The second component, which compliments and mates with the first component, has an engaging surface that coordinates with an end of the piston. The force applied to the pressure member causes the pressure member to distort and apply pressure to the piston to extend the piston outward to interact with the engaging surface of the second component to restrain the second component.

  • Patent number: 8127476
    Abstract: A connector for earth-moving equipment subjected to contact with earth, abrasive materials and the like has a nut with a body and a hole extending through the body. A bolt with a shank adapted to extend into the hole has an enlarged head at one end of the shank. Cooperating thread formations are defined on the shank and in the hole. The thread formations have cooperating matching cross-sections that decrease from a vicinity of the head of the screw towards the other end of the screw and that extend over a circumference of less than 360° and typically of no more than 270°. The connector is adapted to connect various components, including teeth and adapters, to each other and to lips at the front end of earth moving buckets and the like.
