Patent number: 12596004Abstract: A system for determining a position of a pin inserted within a pinhole of a work machine is disclosed. The system includes a follower, a sensor, and a controller. The follower is biased to be in contact with the pin to follow the pin throughout a movement of the pin within the pinhole. The sensor is configured to detect a state of the follower corresponding to the position of the pin with respect to the pinhole. The controller is configured to determine the position of the pin based on the state of the follower.Type: GrantFiled: June 12, 2023Date of Patent: April 7, 2026Assignee: Caterpillar Inc.Inventors: Faheem Mohammed Konnakkodan, Riley Aaron Albers, Matthew Thomas Hansen, David Michael Worth

Publication number: 20260062895Abstract: A wear plate for a work implement of a work machine includes a body extending along a longitudinal axis, a lateral axis orthogonal to the longitudinal axis, and a vertical axis orthogonal to the longitudinal axis. The body defines an engagement surface, an operational surface opposite the engagement surface, and a cut-out extending from the engagement surface to the operational surface. The wear plate also includes at least two projections extending outwards from the engagement surface along the vertical axis. Each of the at least two projections is adapted to be received within a base structure of the work implement to removably couple the wear plate with the work implement, such that the at least two projections are isolated from the operational surface of the wear plate.Type: ApplicationFiled: August 28, 2024Publication date: March 5, 2026Applicant: Caterpillar Inc.Inventors: David Michael Worth, Riley A. Albers

Patent number: 12523016Abstract: A work implement for a construction machine includes a collection member, a first side wall, a second side wall, and a plate member coupled to the collection member, the first side wall, and the second side wall. The collection member, the first side wall, the second side wall, and the plate member together define a hollow space. Further, at least one of the first side wall, the second side wall, and the plate member define an opening that communicates with the hollow space. The work implement further includes a sensor mounting system including a cover, a plurality of mechanical fasteners adapted to couple the cover with the work implement, and a sensor mounted on the cover. Upon coupling of the cover with the first side wall, the sensor is partially received within the hollow space.Type: GrantFiled: July 7, 2022Date of Patent: January 13, 2026Assignee: Caterpillar Inc.Inventors: Riley A. Albers, David Michael Worth

Patent number: 10246848Abstract: A hinge attachment bracket for use with a work implement is provided. The bracket comprises a substantial I-beam configuration that includes a first flange, a second flange, a web that connects the first flange to the second flange and that defines a boss that defines a pin receiving bore that establishes a radial direction, a radial plane and a longitudinal axis. The first and second flanges may merge toward each other tangentially forming a first extension portion.Type: GrantFiled: January 11, 2016Date of Patent: April 2, 2019Assignee: Caterpillar Inc.Inventor: David Michael Worth

Patent number: 9957689Abstract: A tilt bucket may include a front structure having an outer surface, the front structure including a base plate with a bottom surface. The tilt bucket may include a bottom edge and a curved wrapper extending between the base plate and the bottom edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the bottom edge to the tangent point on the outer surface of the front structure, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.64 to 0.70.Type: GrantFiled: September 28, 2015Date of Patent: May 1, 2018Assignee: Caterpillar Inc.Inventors: Ryan Andrew Rochel, Julia Kay Nitti, David Michael Worth, Davida Ray Reang, Giedre Simanskaite
