Patent number: 11732814Abstract: A plug valve assembly has a valve body with an inlet and an outlet each defining a fluid passageway in fluid communication with a cavity defined within the valve body. The valve body further has a collar defining a service opening extending upward from the valve body. A plug with a spindle top and a plug body is disposed within the cavity. The plug has an opening that is operable to obstruct the fluid passageway when it is in a closed position and to connect the inlet to the outlet when it is in an open position. The spindle top of the plug has a hexagonal outer profile and a through opening and adaptable to engage with a variety of actuating devices. A threaded cap is removably engaged with the collar of the valve body and is operable to retain the plug within the valve body cavity.Type: GrantFiled: October 19, 2021Date of Patent: August 22, 2023Assignee: SPM Oil & Gas Inc.Inventors: James D. McPhail, Peter Allan Manos, David H. Graef, Daniel Stumpo

Patent number: 8807669Abstract: An apparatus and method for preventing debris from accessing and wrapping around the axles of a vehicle, such as a landfill compactor, are disclosed. The apparatus may include a wheel having a rim from which radially extend a plurality of cleats or tips. A subset of tips may be provided circumferentially around a laterally inner edge of the wheel. A wheel guard may be mounted between adjacent pairs of tips of the subset. Each wheel guard may be welded to the rim and to the adjacent pairs of tips. Each wheel guard may be a unitary piece of metal, or could be provided in two or more segment so as to be adjustable and thus facilitate use on wheels of differing diameters, or with different tip spacing. The wheel guards and adjacent tips form a continuous barrier around the circumference of the wheel to prevent debris from accessing and wrapping around the axles of the compactor.Type: GrantFiled: March 17, 2011Date of Patent: August 19, 2014Assignee: Caterpillar Inc.Inventors: James D. McPhail, Michael Hans Hinrichsen, Randy E. Schoepke

Patent number: 8496402Abstract: A compactor wheel tip for a landfill or soil compactor comprises a bottom wall having a wheel engaging surface, a top wall having a ground engaging surface, oppositely disposed front and rear walls having concave surfaces, and oppositely disposed side walls. The ground engaging surface of the top wall may be generally planar and have a “bow-tie”-shaped cross-section, or the top wall may define a pair of shoulders each extending inwardly from one of the side walls, and a rib extending between the shoulders and having a depth that is less than the depth of shoulders. The ground engaging surface may further define a pair of exterior pockets disposed on opposite sides of the rib and extending downwardly between the rib and corresponding portions of the front and rear walls.Type: GrantFiled: June 30, 2010Date of Patent: July 30, 2013Assignee: Caterpillar Inc.Inventors: James D. McPhail, Michael Hans Hinrichsen, Randy E. Schoepke

Patent number: 8449218Abstract: A compactor wheel tip assembly for a landfill or soil compactor comprises a base with a tip attached thereto. A base engaging surface of the tip and a tip engaging surface of the base face and abut when the tip is attached to the base. The tip and base engaging surfaces may have corresponding geometries so that the tip may be attached the base in either a forward and rearward traction position or a side-slop traction position. The tip may include pocket walls having concave surfaces, and a ground engaging surface of a top wall that may be generally planar with a “bow-tie”-shaped cross-section or may define a pair of shoulders, a rib extending between the shoulders, and exterior pockets disposed on either side of the rib.Type: GrantFiled: June 30, 2010Date of Patent: May 28, 2013Assignee: Caterpillar Inc.Inventors: James D.

Publication number: 20090313805Abstract: A compactor tip assembly for a landfill or soil compactor comprises a base and a tip that are formed from dissimilar materials. The tip may be formed from high carbon steel for wear resistance, while the base may be formed from low carbon steel for easy welding. The compactor tip assembly is attached to the compactor wheel by welding the base to the wheel. The tip and the base each have ground engaging surfaces which may be complementary to one another. A hollow pocket may be formed through the base and in the tip.Type: ApplicationFiled: September 1, 2009Publication date: December 24, 2009Inventors: James D. McPhail, Michael H. Hinrichsen
