Abstract:
An adapter for a multipiece excavating tooth assembly, comprising:an elongated member having a base portion and an elongated nose portion axially arranged relative to each other along a longitudinal centerline of said member, said base portion being configured to permit attachment of said adapter to excavating equipment, and wherein said elongated nose portion terminates at a free forward end and has top and bottom angled surfaces disposed generally above and below the longitudinal centerline of said member, respectively, with the top surface of said nose portion having two downwardly disposed and angled sides arranged on opposite lateral sides of the longitudinal centerline of said member, and with the bottom surface of said nose portion having two upwardly disposed and angled sides arranged on opposed sides of the longitudinal centerline of said member, and with said nose portion further defining an opening disposed adjacent a rear end of the nose portion, said opening extending along an axis intersecting opposite sides on the top and bottom angled surfaces of the nose portion of said member, and wherein the angled side on the bottom surface of said nose portion intersected by the axis of said opening defines a counterbore arranged concentric relative to said axis for accommodating a retainer ring of a retaining apparatus, and wherein an outer peripheral margin of said counterbore is wholly surrounded by said angled side on the bottom surface of said nose portion intersected by the axis of said recess to add strength and rigidity to a weakened area of the adapter.
