20080201997 | Tooth and Adaptor Assembly - Abstract A tooth and adaptor assembly ( | 08-28-2008 |
20090199442 | Excavation retention assembly - An excavation retention assembly is provided for mounting a tooth to an excavating apparatus. The assembly in one embodiment includes a tooth and an adaptor end of a working member of an excavating apparatus. The tooth includes a cavity for mating with an end of the adaptor, an opening for receiving a fastening member and a fastening receptacle in the cavity opposite the opening in the tooth for receiving the fastening member. The adaptor includes a passage which aligns with the opening in the tooth and the fastening member. The fastening member passes through the aligned opening of the tooth, the passage of the adaptor and into the fastening receptacle for securing the tooth to the adaptor. | 08-13-2009 |
20090277050 | Wear Assembly For Excavating Equipment - A wear assembly for excavating equipment includes a base fixed to the excavating equipment, a wear member fit over the base, and a lock to releasably hold the wear member to the base. The wear member includes side relief to reduce drag on the system. The wear member and the base each includes a hemispherical front end and a generally trapezoidal rear portion. The base includes a nose and a stop projecting from the nose to cooperate with the lock without an opening being needed to receive the lock into the nose. The lock is an elongate lock positioned generally in an axial direction and which holds the wear member to the base under compressive loads. | 11-12-2009 |
20120304508 | A WEAR MEMBER ASSEMBLY - A wear member assembly for a lip of an earth excavating device comprises a first wear member, a second wear member and a retaining pin. The first wear member is mounted to the lip. The first wear member includes a boss extending outwardly from one of its opposite sides. The second wear member is mounted adjacent the first wear member. The second wear member includes a socket in one of its sides. The socket is adapted to receive the boss of the first wear member. The second wear member includes a retaining pin passage in communication with the socket. The retaining pin is removably located in the retaining pin passage. The retaining pin has a first bearing face adapted to oppose and engage a face of the boss received in the socket and a second bearing face which bears against a load bearing face of the retaining pin passage. | 12-06-2012 |
20120311896 | EXCAVATION TOOTH ASSEMBLY - A lock for an excavation tooth assembly, the lock comprising: a body; first and second engaging portions mounted to the body and movable between respective first and second positions; wherein the engaging portions being interdependent so that movement of at least one of the first and second engaging portions causes a corresponding movement of the other of the first and second engaging portions. | 12-13-2012 |
20160083935 | EXCAVATION TOOTH ASSEMBLY - An excavation tooth lock assembly to lock a first tooth member to a second tooth member, the first tooth member having a body that incorporates a socket which is configured to receive a nose portion of the second tooth member, a locking space provided when the second tooth member is received in the first tooth member, wherein the lock assembly comprises: a lock comprising a body which is configured to be inserted into the locking space including by rotating the body into an operative position to lock the first tooth member to the second tooth member and interengaging elements disposed on the lock and one or both of the first and second tooth members, the elements configured to releaseably retain the lock within the locking space in its operative position. | 03-24-2016 |

20140259812 | 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 portion extending from the head portion. The C-shaped portion may define a lock slot between two circumferential ends for receiving a portion of a support member to be locked with the ground engaging tool. The C-shaped portion may further include an outer surface configured to be rotatably received in an inner surface of a retainer bushing, an inner surface configured to contact the portion of the support member, and a base extending between the outer surface and the inner surface. The base may include a helical surface with a depth increasing from a first end to a second end. | 09-18-2014 |
20140259813 | 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 portion extending from the head portion. The C-shaped portion may include an inner surface extending between a first circumferential end and a second circumferential end to define a lock slot. The inner surface may include a first inner surface extending from the first circumferential end to a midpoint between the first circumferential end and the second circumferential end and a second inner surface extending from the second circumferential end to the midpoint. The first inner surface and the second inner surface may be symmetrical with respect to a first plane substantially parallel to a lock rotation axis. On a plane substantially perpendicular to the lock rotation axis, a distance between the first circumferential end and the second circumferential end may be less than a maximum distance between the first inner surface and the second inner surface in a direction perpendicular to the first plane. | 09-18-2014 |
