| 20150052787 | SELF-ADJUSTING CONNECTOR APPARATUS FOR TELESCOPED GROUND ENGAGING WEAR AND SUPPORT MEMBERS - Telescoped ground engaging telescoped wear and support members are provided with self-adjusting connector apparatus that releasably retains the wear member in a rearwardly telescoped orientation on the support member. In illustrated embodiments thereof, the connector apparatus includes cooperating ratchet structures operatively associated with the support and wear members and functioning to automatically re-tighten an abrasion-created loosened interfit between the wear and support members in response to a rearwardly directed operational force imposed on the wear member. | 02-26-2015 |
| 20150082671 | RELIABLE CONNECTION SYSTEM AND ASSEMBLIES AND METHODS FOR USING THE RELIABLE CONNECTIONS - 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. | 03-26-2015 |
| 20150089848 | WEAR ASSEMBLY - A wear assembly with strain relief protects exposed surfaces of excavating equipment such as a bucket lip. Wear components may include a seat where loads are applied, welding flanges flanking the seat on opposite ends of the component welded to the equipment, and strain relief areas between each welding flange and the seat. The strain relief balances stresses from loading in the wear assembly across the weld flange to limit cracking from stress concentrations. Strain relief may include modification of material properties or modification of component configuration to reduce stiffness of the component between the weld flanges and the seat. | 04-02-2015 |
