20130086825 | IMPLEMENT TOOTH ASSEMBLY WITH TIP AND ADAPTER - A ground engaging tooth assembly for a cutting edge of a ground engaging implement may include an adapter and a ground engaging tip. The adapter may have a forward extending adapter nose having an inverted or reverse keystone-shaped contour, with the ground engaging tip having a nose cavity for receiving the adapter nose and exterior surfaces having complementary shapes to the adapter nose. The adapter nose and an adapter cavity of the tip may also be configured with complimentary surfaces that increase retention between the adapter nose and the tip when downward forces are applied to the tip. In other embodiments, the surfaces of the tip may include reliefs extending inwardly into the body of the tip to reduce weight and facilitate penetration of the tip into work material as wear material wears away from a front edge of the tip. | 04-11-2013 |
20130086826 | IMPLEMENT TOOTH ASSEMBLY WITH TIP AND ADAPTER - A ground engaging tip of a tooth assembly for a base edge of a ground engaging implement, is provided, wherein the tooth assembly includes an adapter configured for attachment to a base edge of the ground engaging implement and having a forwardly extending adapter nose. In various embodiments, the ground engaging tip is configured for digging into work material in diverse earth moving environments. | 04-11-2013 |
20130086827 | IMPLEMENT TOOTH ASSEMBLY WITH TIP AND ADAPTER - A ground engaging tip of a tooth assembly for a base edge of a ground engaging implement, is provided, wherein the tooth assembly includes an adapter configured for attachment to a base edge of the ground engaging implement and having a forwardly extending adapter nose. The adapter nose and an adapter cavity of the tip may be configured with surfaces to increase retention when downward forces are applied to the tip. | 04-11-2013 |
20130086828 | IMPLEMENT TOOTH ASSEMBLY WITH TIP AND ADAPTER - A ground engaging tip of a tooth assembly for a base edge of a ground engaging implement, is provided, wherein the tooth assembly includes an adapter configured for attachment to a base edge of the ground engaging implement and having a forwardly extending adapter nose. The ground engaging tip may have a substantially keystone-shaped contour providing additional wear material at the top surface for use in top-wearing earth moving applications. | 04-11-2013 |
20130145659 | EDGE PROTECTOR FOR GROUND ENGAGING TOOL ASSEMBLY - An edge protector for mounting to a lip of a ground engaging tool and shielding an edge of the lip is disclosed. The edge protector may include a tip configured to extend forward from the edge of the lip of the ground engaging tool. The edge protector may also include a first mounting leg extending rearward from the tip. Additionally, the edge protector may include a second mounting leg extending rearward from the tip and spaced from the first mounting leg by a recess configured to receive the lip of the ground engaging tool between the first mounting leg and the second mounting leg. The first mounting leg may include a lock cavity configured to house a lock in such a manner that the lock is sandwiched between the first mounting leg and the lip of the ground engaging tool. | 06-13-2013 |
20140259807 | RETAINER SYSTEMS FOR GROUND ENGAGING TOOLS - Disclosed are various exemplary embodiments of a retainer bushing for use with a lock in a ground engaging tool. The retainer bushing may include a skirt extending around a retainer axis, where the skirt may include an outer surface configured to mate with a lock cavity of the ground engaging tool and an inner surface configured to rotatably receive an outer surface of the lock. The retainer bushing may also include a detent projection extending radially inward from the inner surface with respect to the retainer axis and configured to engage a detent recess of the lock to releasably hold the lock. The detent projection may include a convex surface with a substantially constant radius, and a center of the radius of the convex surface may be positioned at a first distance from the retainer axis that is greater than a second distance between the retainer axis and the outer surface of the skirt. | 09-18-2014 |
20140259808 | RETAINER SYSTEMS FOR GROUND ENGAGING TOOLS - Disclosed are various exemplary embodiments of a lock for a ground engaging tool. The lock may include a head portion and a C-shaped skirt extending from the head portion. The skirt may define a lock slot for receiving a portion of a support member to be locked with the ground engaging tool. The skirt may also include an outer surface configured to be rotatably received in an inner surface of a retainer bushing. The outer surface may include a recessed portion that is configured to create a gap between a base surface of the recessed portion and the inner surface of the retainer bushing when the outer surface of the skirt is rotatably received in the inner surface of the retainer bushing. | 09-18-2014 |
20140259810 | RETAINER SYSTEMS FOR GROUND ENGAGING TOOLS - Disclosed are various exemplary embodiments of a retainer bushing for use with a lock of a ground engaging tool. The retainer bushing may include a skirt extending around a retainer axis, where the skirt may include an outer surface configured to mate with a lock cavity of the ground engaging tool and an inner surface configured to rotatably receive an outer surface of the lock. The retainer bushing may also include a detent projection extending radially inward from the inner surface and configured to engage a detent recess of the lock to resist rotation of the lock. The skirt and the detent projection may be integrally constructed of a thermoplastic material comprising polyoxymethylene. | 09-18-2014 |
