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: 9222353Abstract: A tip for use on an earth working roll for mining, construction and public works machines such as crushers, surface miners, milling machines and the like includes a working end provided with side relief to reduce drag and wearing, require less power to drive the rolls, and lengthen the usable life of the tip. The working end can also have a generally flat front surface to improve the yield in a crushing or other similar operation. The tip includes a base and a wear cap releasably secured together by a retainer.Type: GrantFiled: January 8, 2009Date of Patent: December 29, 2015Assignee: ESCO CorporationInventors: Ray J.

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. The separate mounting component can be easily manufactured and secured within the wear member for less expense and higher quality than forming the threads directly in the wear member.Type: GrantFiled: July 12, 2012Date of Patent: December 29, 2015Assignee: ESCO CorporationInventors: Mark A.
