Abstract: An excavating adapter/tooth point assembly has an interfit configuration in which the front end surface of the adapter base has a curved front surface portion that slidingly and complementarily engages a facing curved rear end surface portion of the tooth point. The adapter nose received in the tooth point pocket is somewhat smaller in cross-section that the pocket to permit a limited vertical rocking movement of the point relative to the adapter nose, about a connector structure captively retaining the point on the adapter nose, while transferring rearwardly directed excavating loads on the point to the curved sliding adapter/point interface area. Top and bottom sides of a rear end portion of the point have curved ear projections which extend rearwardly and outwardly along the adapter base and function as built-in wear guards that protect underlying surface portions of the adapter base.

Abstract: A connector pin assembly for releasably retaining a replaceable excavating tooth point on an adapter nose has opposite rigid body portions that are threadingly connected to one another in a manner permitting them to be selectively moved axially toward and away from one another, and a resilient structure captively retained between facing ends of the body portions. The connector pin assembly may be operatively inserted into the aligned point and adapter openings without the need to pound it in. Once the connector pin assembly is in place within the point and adapter openings the rigid body portions are threadingly moved toward one another to thereby compress the resilient structure in a manner forcing it against an interior surface portion of the adapter opening.

Abstract: An elongated excavating tooth assembly includes a replaceable tooth point and an adapter structure comprising (1) an intermediate adapter having a front end nose complementarily received in a rear end pocket of the point and captively retained therein by a first connector pin structure, and (2) a main adapter having a front end nose complementarily received in a rear end pocket of the intermediate adapter and captively retained therein by a second connector pin structure, and a rear end operatively securable to an excavating bucket lip. Special configurations of the point and adapter portions of the assembly, including horizontally elongated oval configurations of the noses, horizontal orientation of the connector pins, nose stabilization bosses at the nose connector openings, and complementarily scalloped adapter and point interface areas, provide the assembly with reduced size and improved strength, wear and operational characteristics.

Abstract: A generally C-shaped wear member, representatively an excavating tooth adapter, is mounted on a front edge portion of an excavating bucket lip with top and bottom leg portions of the adapter respectively extending along top and bottom sides of the lip and interlocked with top and bottom ends of a base structure removably received in an opening in the lip. The top and bottom legs of the adapter are respectively and removably secured to the top and bottom ends of the base structure with top and bottom fastening structures. The bottom fastening structure has a disconnection portion which is conveniently accessible from a front bottom location on the adapter, and is useable to disconnect the bottom leg of the adapter from the base without having to reach under the lip to the rear end of the bottom adapter leg to effect such disconnection.

Abstract: An excavation tooth point longitudinally extending along an axis and having a pocket area extending inwardly through a rear end thereof is telescoped onto a nose portion of an adapter structure by inserting the nose portion into the tooth point pocket area. The inserted nose portion has a tapered side opening therein that is positioned between a corresponding pair of similarly tapered tooth side wall openings. The tooth point is removably coupled to the adapter nose using an elongated, wedge shaped connector member which is inserted, small end first, through the generally aligned tooth and adapter openings. An internal passage longitudinally extends through the large connector member end and receives an inner portion of a force exerting member which compresses a spring within the passage, the spring in turn resiliently biasing an outer portion of the force exerting member into abutment with an interior surface portion of the tooth.

Abstract: A wear runner assembly is attached to a surface of an excavating bucket and serves to protect a portion of the surface from abrasion wear during use of the bucket. The assembly includes a base member, a wear runner member, a pair of bolts and a pair of conical locking nuts. The base member is welded to the surface and has a pair of undercut slots that captively retain the head portions of the bolts, with the bolt bodies being transverse to the surface and projecting outwardly beyond the outer side of the base member. The wear runner member is mounted on the base member by moving the wear runner member toward the base member in a direction transverse to the surface in a manner causing the outwardly projecting bolt body portions to enter and be recessed within a pair of openings formed through the wear member, and also causing projections on the base member to be complementarily received within recesses formed in the wear runner member.

Abstract: A wear resistant excavating apparatus provides reduced wear, resilient compensation for such wear, reduced time required for installation, maintenance, and repair, and reduced hazards of operation. In a preferred embodiment, a wear resistant excavating apparatus has a lip which penetrates the earth, a structure which overlaps the lip, a fastener which biases the overlapping structure to contact the lip, and a compression member which resiliently maintains the overlapping structure in contact with the lip.

Abstract: An excavation tooth point longitudinally extending along an axis and having a pocket area extending inwardly through a rear end thereof is telescoped onto a nose portion of an adapter structure by inserting the nose portion into the tooth point pocket area. The inserted nose portion has a tapered side opening therein that is positioned between a corresponding pair of similarly tapered tooth side wall openings. To removably couple the tooth point to the adapter nose an elongated, wedge shaped connector member is inserted, small end first, through the generally aligned tooth and adapter openings. A bolt is then passed through a central opening in a flat spring member and tightened into a threaded axial opening in the small connector member end.

Abstract: An adjustable golf putter provides configurable characteristics of striking face-to-shaft lateral alignment, center of gravity, shaft-to-head longitudinal alignment, head-to-shaft angle, total weight, weight distribution, and targeting. In a preferred embodiment, a golf club has a shaft attached to a putter head, the head having a hosel assembly and weight assemblies clamped between opposing face plates.

Abstract: An upper end portion of an excavation ripper shank is captively and removably retained in a ripper box using a specially designed flex pin connector longitudinally driven into generally aligned openings in the ripper box and shank. The connector includes first and second rigid pin members held in a spaced apart, parallel, laterally facing relationship by a plurality of elastomeric members bonded to facing side surfaces of the pin members. When the connector is driven into the aligned box and shank openings the elastomeric members are compressed, causing the first and second pin members to drive the shank and box into forcible abutment with one another to substantially eliminate relative side-to-side play therebetween. Additionally, as the connector passes through the first and second openings its first and second pin members are caused to pivot relative to one another about an axis parallel to the compression direction of the elastomeric members.

Abstract: An elongated resilient wedge and spool retaining structure longitudinally extends through generally aligned openings formed in a replaceable excavating tooth point, and an adapter nose portion received in a tapered socket within the tooth point, to captively hold the tooth point in place on the adapter nose. The retaining structure includes a tapered spool member having an enlarged side portion received in the tooth socket and blocking removal of the spool member, and a tapered wedge member driven into the tooth and adapter openings to a position in which longitudinally extending series of ratchet teeth on facing sides of the spool and wedge members are intermeshed and releasably lock the structure in place within the tooth and adapter assembly. A recess formed in a nontoothed side of the wedge member receives a locking member that forcibly bears against a surface portion of the adapter nose opening and is movable into the recess in a manner compressing a plurality of elastomeric members therein.

Abstract: A retaining mechanism (10) for captively retaining an adapter (4) to the forward lip (2) of a bucket for earth excavating utilizes a ratcheted pawl (14) within a C-clamp (12). The pawl ratchet (24) engages a complementary pawl surface (26) of the rear half (16b) of a split pin assembly (16). The forward half (16a) of the split pin can be attached to the rear half (16b) by shear screws (52). Moreover, the forward half (16a) of the split pin can be attached to the rear half (16b) by an elastomeric element (64). The split pin assembly (16) acts as a wedge member, firmly securing the adapter (4) to the lip (2). To remove the retaining mechanism (10) from the adapter (4) and lip (2), the pawl (14) may be disengaged from the rear split pin (16b) by manipulating the pawl through an access port (28 ) in the C-clamp (12). Alternatively, the forward split pin (16) may be driven through the opening in the adapter and lip.
