Patent number: 11359355Abstract: A wear assembly for use on various kinds of earth working equipment that includes a base with a supporting portion, a wear member with a cavity into which the supporting portion is received, and a lock to releasably secure the wear member to the base. The supporting portion is formed with top and bottom recesses that receive complementary projections of the wear member. These recesses and projections include aligned holes so as to receive and position the lock centrally within the wear assembly and remote from the wear surface. The hole in the wear member is defined by a wall that includes a retaining structure provided with an upper bearing surface and a lower bearing surface for contacting and retaining the lock against upward and downward movement in the hole. The lock includes a mounting component that defines a threaded opening for receiving a threaded pin that is used to releasably hold the wear member to the base.Type: GrantFiled: May 18, 2018Date of Patent: June 14, 2022Assignee: ESCO GROUP LLCInventors: Mark A. Cheyne, Noah D. Cowgill, Michael B. Roska, Donald M. Conklin, Scott H. Zenier, Chris J. Hainley

Patent number: 11155982Abstract: Wear members for wear assemblies include a lock configured to secure the wear member to a base, where the lock has two engagement positions, namely: (a) a first position that secures the lock to the wear member, and (b) a second position that secures the wear member to the base. The locks are further configured to be unlatched and removed from the wear member in two phases, a first retraction of the latching mechanism, followed by a rotation of the lock itself with removal from the wear member.Type: GrantFiled: April 14, 2020Date of Patent: October 26, 2021Assignee: ESCO GROUP LLCInventors: Christopher A. Johnston, Donald M. Conklin, Michael B. Roska, William D. Rossi, Kevin S. Stangeland

Patent number: 10829912Abstract: A wear assembly for excavating equipment which includes a wear member and a base each with upper and lower stabilizing surfaces that are offset and at overlapping depths to reduce the overall depth of the assembly while maintaining high strength and a stable coupling. The nose and socket each includes a generally triangular-shaped front stabilizing end to provide a highly stable front connection between the nose and wear member for both vertical and side loading. The lock is movable between hold and release positions to accommodate replacing of the wear member when needed, and secured to the wear member for shipping and storage purposes.Type: GrantFiled: November 10, 2017Date of Patent: November 10, 2020Assignee: ESCO GROUP LLCInventors: Christopher M. Carpenter, Donald M. Conklin, James E. Bearden, Severn D. Durand, Dziugas Radzius, Ray J. Morris
