Ears extend back from the tooth point on both sides of the adapter and define apertures adapted to receive pins. A hole in the adapter is also adapted to receive the pins. The pins extend through the apertures and into the hole, thus fixedly connecting the tooth point to the adapter. To remove the tooth point, both pins can be driven into the adapter hole and housed there concurrently. The tooth point can then be removed and the pins later driven out of the hole. A lock system also connects a main body pin to a rigging part. The lock system is particularly suited to large rigging parts, such as for draglines.

    Abstract: A shank and replaceable tip of a ground working implement are defined from flat plate which is cut by laser or similar or is stamped to provide interconnecting elements between the replaceable tip and the lower end of the shank. At the lower end of the shank is provided a pocket defined by a recess cut into the lower end and a pair of plates welded on respective sides of the flat plate so that the projection of the replaceable tip extends into the pocket to hold the tip in place. This allows a rugged construction of the tip and various designs of tip can be manufactured simply by reprogramming the cutting process. A guide surface is mounted on the front plate of the shank with that guide surface defining a channel member with a leading edge increasing in radius of curvature from the lower end of the shank upwardly to a top of the guide surface spaced upwardly from the ground. This increase in width of the guide surface assists in discarding trash.

  • Patent number: 5881480
    Abstract: A high wear-resistant grader blade which combines two high wear-resistant elements in the lower end of the blade. First, high wear-resistant particles are embedded into the front leading edge of the blade. More particularly, the leading edge of the blade is heated to pool molten metal. Tungsten carbide particles are then added to the pooled molten metal so as to blend with the molten metal. Upon cooling, the tungsten carbide particles mixed with the melted grader blade metal, will penetrate into the surface of the grader blade and will form a protrusion outward from the surface of the grader blade. Thus, the leading edge of the grader blade will be formed of a mixture of tungsten carbide and the grader blade material. Second, a groove is milled down the center of the grader blade and high wear-resistant inserts laid end-to-end are brazed into the groove.

  • Patent number: 5553409
    Abstract: A wear protector system for shielding the leading edge of an earthmoving implement such as a loading bucket includes an arrangement of shrouds which cover the leading edge between the laterally spaced digger teeth. Each shroud has a nose portion that wraps around the leading edge and a rearwardly extending tail portion having an abutment surface that engages an undercut abutment surface of an anchor block that is welded to the bucket. The complementary abutment surfaces retain the tail portion from moving upwardly away from the bucket surface, whereas the shroud is retained from movement forwardly out of engagement with the lip by use of a cotter pin extending transversely through a passage that is formed partially in the tail of the shroud and partially in the anchor.

  • Patent number: 5412885
    Abstract: Edge protectors for the leading portions of base edges have been utilized in many application to protect the leading portion of the base edge. It is advantageous to have an edge protector that is readily removed and replaced without having to remove additional elements. In the subject arrangement, a base edge protector assembly is included having a protector mounting lug and a replaceable lip protector. The protector mounting lug has a pair of spaced apart bosses and a laterally disposed flange therebetween while the lip protector has a cavity and load transferring surfaces located in the cavity. When assembled the load transferring surfaces are in mating contact with the laterally disposed flange of the protector mounting lug. First and second pairs of aligned openings are located in the lip protector and, when assembled, are in general alignment with the openings located in each boss of the pair of bosses. Flex pins are disposed in the openings to secure the lip protector to the protector mounting lug.

  • Patent number: 5333696
    Abstract: Reversible protectors are normally utilized to protect the leading edge of a work member from high wear during use. It is also advantageous to have a reversible protector that can be secured to a work member even though the work member may be composed of several components which are welded together thus adversely affecting the tolerances between the various components. In this subject arrangement, a reversible protector is provided and adapted to be mounted on and secured to a work member. The reversible protector has recesses located in the lower end thereof which, when assembled, are in mating engagement with protuberances on the work member. This mating engagement secures the lower end of the reversible protector to the work member. A pair of aligned openings are provided near the other end thereof which aligns with a transverse hole in the work member for receiving a retaining mechanism therethrough.
