Abstract
The invention is concerned with a unitary high strength earth working tooth useful with excavator buckets, scrapers, rippers and the like. The tooth is integrally formed and includes a proximal end for attachment to an earth working machine and a distal end for penetrating soil. The proximal end includes a generally isosceles trapezoidal upper portion, a generally isosceles trapezoidal lower portion, and a pair of generally isosceles trapezoidal sides, each side extending from an edge of said upper portion to an edge to said lower portion, a closure interconnecting the shorter bases of said upper portion, said lower portion and said two sides, and a pair of aligned holes, one through each of said sides generally on the bisecting axis thereof. The distal end includes a generally flat isosceles trapezoidal member extending at an obtuse angle from said lower portion with the larger base of said member coextensive with the shorter base of said lower portion, said member extending generally parallel to a plane defined by the bisecting axes of said sides. The tooth, when viewed from the side, includes a generally right triangularly shaped ridge upraised perpendicularly from the bisecting…
