  • Publication number: 20250027298
    Abstract: A retention mechanism may have a pin inserted into a retainer pin opening in the adapter. The retention mechanism may also have a spring clip inserted into the tip through a first end of a transverse hole in the tip, and a retainer inserted through a second end of the transverse hole. The retainer may have a retainer body extending from a first axial end to a second axial end. The retainer may have at least one tab extending radially from the retainer body at the first axial end. The at least one tab may engage with a female thread in the transverse hole. The retainer may have at least one detent cutout disposed on an outer surface of the retainer body for receiving a portion of the spring clip. The retainer may also have an axial cavity at the second axial end for receiving one end of the pin.

  • Publication number: 20250027296
    Abstract: A ground engaging tip assembly includes a ground engaging tip, an adapter, and a retention mechanism. The ground engaging tip includes an inner surface extending inward from a rear edge defining a nose cavity within the ground engaging tip. The nose cavity includes a front inner surface, top inner surface, bottom inner surface, and oppositely disposed side inner surfaces. The top inner surface includes a front portion proximate the front inner surface comprising a front central surface connecting two opposing front side-sloping surfaces and a rear portion proximate the rear edge comprising a rear central surface connecting two opposing rear side-sloping surfaces. The bottom includes a tapered bottom channel. The adapter includes a nose portion configured to be inserted into the nose cavity of the ground engaging tip. The retention mechanism is configured to secure the ground engaging tip to the adapter.

  • Publication number: 20250027299
    Abstract: A retention mechanism for connecting a ground engaging tip and an adapter has a spring, a retainer block configured for insertion into a cutout in the adapter, and a retainer. The retainer block has a cavity having an internal thread. The retainer block also has an outer surface defining a contact surface, a back surface opposite the contact surface, and a plurality of angled surfaces between the contact surface and the back surface. Further, the retainer block has a slot passing through the back surface and configured to receive the spring. The retainer is configured for insertion in in the cavity of the retainer block. The retainer has a threaded outer surface configured to engage with the internal thread of the retainer block, a detent cutout configured to receive a portion of the spring, and a chamfered bottom surface configured to engage with and deflect the portion of the spring.

  • Patent number: 12054921
    Abstract: A corner guard includes a rear attachment portion defining a first fastener receiving void, a rear edge that is disposed along the direction of material flow, and a forward ramp portion that extends forwardly from the rear attachment along the direction of material flow, and vertically downwardly forming a front wear edge. The corner guard also includes an outer lateral side, and an inner lateral side. The outer lateral side is flared laterally, defining an outer lateral side extremity that is disposed along the direction of material flow adjacent to the front wear edge, forming a flared portion.

  • Patent number: 11649614
    Abstract: A retainer sleeve configured for use in a retainer system for a ground engaging tool includes a plurality of plate-like sections, each section being flexibly joined with an adjacent section along either a radially inner edge or a portion of a radially outer edge. The radially inner edges of the plurality of sections form part of a segmented inner surface configured for engagement with an outer surface of a locking member of the retainer system. The inner surface extends partially around a central axis of the retainer sleeve to form a substantially C-shaped retainer sleeve having opposite circumferential ends that are spaced from each other. The radially outer edges of the plurality of sections form part of a segmented, frustoconical outer surface configured for engagement in an internal lock cavity of a ground engaging tool tip.
