ABSTRACT:
A sweeper drag shoe is formed of an elongated, flat, inverted channel filled with a matrix made of irregular shaped, packed together, hard carbide particles and soft, ductile relatively resilient brazing metal filling the spaces between and generally surrounding and brazing together the particles. The exposed matrix provides a ground engaging face which resists wear due to abrasion. The brittle carbide particles are protected against road shock caused breakage by means of the ductile brazing material absorbing impact loads and permitting limited relative movement of the particles within the solid matrix.
