Patent number: 10677054Abstract: A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.Type: GrantFiled: July 29, 2016Date of Patent: June 9, 2020Assignee: Joy Global Underground Mining LLCInventors: Randy Arnold, James E. Folkerts, John R. Frederick, John Hallberg, James Krellner, David Meade, Bulent Tiryaki, Charles Simon James Pickles, Peter Robert Bush, Christopher John Howard Wort, Serena Bonetti, Bernd Heinrich Ries, Markus Kilian Scharting

Patent number: 10144316Abstract: A mining shuttle car that trams on underground roadways includes a conveyor system and an operator's compartment adjacent to the conveyor system. The operator's compartment includes a rotatable seat and a control station. The operator's seat module is coupled to one or more joysticks that control the car, and the operator's seat module and the control station are mounted on a rotatable platform so as to be rotatable as a unit between a plurality of secured positions for operating the mining shuttle car. Forward movement of the joystick control relative to the seat steers the shuttle car about a point in front of the seat, and rearward movement of the joystick control relative to the seat steers the shuttle car about a point behind the seat. Forward and rearward movement of one of the joysticks steers the mining shuttle car in the same manner regardless of the rotational position of the rotational position of the seat.Type: GrantFiled: February 9, 2015Date of Patent: December 4, 2018Assignee: Joy Global Underground Mining LLCInventors: Adam S. Peterson, Douglas F. Anderson, Terry M. Thomas, Darin M. Sutton, Randy Arnold

Publication number: 20180238170Abstract: A pick tool comprising a strike tip and a pick tool body, the pick tool body including a non-rotating strike tip at a first end of the pick tool body. A shaft is provided at a second end of the pick tool body, the shaft being configured to pass through an opening in a surface of a pick tool holder, the shaft being configured in use to be non-rotationally attached to the pick tool holder. The shaft projects from a pick tool abutment surface such that, when the pick tool is attached to the pick tool holder, the abutment surface abuts the pick tool holder surface. The abutment surface has an aspect ratio between its length and width of between 1.5:1 and 3:1. The pick tool body comprises a leading edge and a trailing edge, the leading edge being, in use, the edge that first contacts a formation, the trailing edge having an angle of less than 18° between a main axis of the pick tool and an axis from the strike tip to the abutment surface at the trailing edge.Type: ApplicationFiled: August 19, 2016Publication date: August 23, 2018Inventors: MARKUS KILIAN SCHARTING, BERND HEINRICH RIES, CHARLES SIMON JAMES PICKLES, SERENA BONETTI, PETER ROBERT BUSH, JAMES FOLKERT, JOHN HALLBERG, JOHN RALPH FREDERICK, BULENT TIRYAKI, JAMES KRELLNER, RANDY ARNOLD, DAVID MEADE
