Publication number: 20190368285Abstract: A locking mechanism for locking a mast includes a double acting cylinder having a piston coupled with a piston rod adapted to slide inside a cylinder barrel. The cylinder barrel is coupled with a first shaft through a first coupling pin. Mounting brackets coupled to a base plate of the mast guide a sliding motion of the first coupling pin, and the cylinder barrel. A first locking pin connected to the piston rod selectively engages a first side plate based on the sliding motion of the piston rod. A retraction stopper restricts a sliding motion of the first locking pin away from the first side plate, and subsequently causes a movement of the cylinder barrel towards the first end of the cylinder barrel. A second locking pin connected to the shaft selectively engages a second side plate based on the sliding motion of the cylinder barrel.Type: ApplicationFiled: June 4, 2018Publication date: December 5, 2019Applicant: Caterpillar Global Mining Equipment LLCInventors: Yagneshwar Natarajan, Charles Taylor Hudson

Patent number: 10443729Abstract: A spring seal for a joint assembly pivotally joining a lever arm to a machine frame includes an annular body having a W-shaped cross section. The W-shaped cross section includes a first cantilevered arm, a parallel and spaced apart second cantilevered arm, and a spring leg joining the first and second cantilevered arms. The spring seal is disposed between a bearing surface on the lever arm and a lug on the frame. The W-shaped cross section of the spring seal can collapse and relax to accommodate movement between the lever arm and the frame lug. A second spring seal can be disposed between a second bearing surface on the lever arm and a second frame lug opposite the first lug.Type: GrantFiled: March 30, 2015Date of Patent: October 15, 2019Assignee: Caterpillar Inc.Inventors: Pradeep Chapagain, Sunil I.

Patent number: 10228057Abstract: A self-adjusting seal for sealing a joint. The joint includes a support member, a mis-alignable component, and a changeable gap between the support member and the mis-alignable component. The seal includes a first part having a generally annular configuration formed of a resiliently crushable material and defining a planar outer seal face to statically seal to the support member and a first seal part opening extending therethrough. A second seal part axially adjoins the first part. The second seal part has a generally annular configuration formed of a rigid material and a second seal part opening extending therethrough in axial alignment with the first seal part opening. The first and second seal part openings define a non-rotation feature to prevent rotation of the seal on the support member, the second seal part defining a planer inner seal face configured to dynamically and sealingly interface with the mis-alignable component.Type: GrantFiled: November 25, 2015Date of Patent: March 12, 2019Assignee: Caterpillar Inc.Inventors: Charles Taylor Hudson, Sunil I.
