Patent number: 10011977Abstract: A lock assembly, and wear assemblies including wear parts incorporating the lock assembly, having a locking pin with a dowel extending outwardly that is received in a slot of a retaining member. The slot of the retaining member has a narrowed section which is narrowed to a width that is less than the cross sectional dimension of the part of the dowel that is received in the narrowed section. In use, the locking pin is rotated and the dowel traverses the slot of the retaining member including passing through, or at least being received by, the narrowed section of the slot. The slot may optionally have a seat that receives the dowel after passing through the narrowed section.Type: GrantFiled: June 14, 2012Date of Patent: July 3, 2018Inventors: Miguel Guimaraes, Bruce Lilley, Josua Kirsch, Edwin Schuetz

Patent number: 9476184Abstract: A lock assembly to lock two members together, typically an excavator wear member, such as a tooth, on to an adaptor. The lock assembly has a locking pin with a flange portion and a retaining assembly that receives the locking pin. The retaining assembly includes a locking member, in the form of a locking ring, which deforms radially when a tapered portion of the locking pin is inserted into the retaining assembly. In the locked position, the locking ring engages with the flange portion of the locking pin to prevent withdrawal of the locking pin from the retaining assembly.Type: GrantFiled: December 10, 2012Date of Patent: October 25, 2016Assignee: CQMS PTY LTDInventors: Douglas Wallis, Miguel Guimaraes, Bruce Lilley, Josua Kirsch, Edwin Schuetz
