ABSTRACT:
A shovel tooth for an earth-moving shovel includes a tooth holder having a hollow shell-like portion fixedly attached to the inner surface of a shovel blade, the shell having an end web extending along the edge of the blade and a projecting portion attached to the end web and extending beyond the blade edge. A tooth cap has a hollow interior dimensioned to receive and frictionally engage the projecting portion, the projecting portion and the tooth cap having aligned opening to receive a fastener such as a bolt. The projecting portion and the interior cavity of the tooth cap are symmetrical about a longitudinal axis of the projecting portion so that the cap can be removed and replaced in either of two positions separated by 180.degree. of cap rotation. The shell and the tooth cap are provided with reinforcing webs which are substantially aligned with each other in the assembled condition. The projecting portion and the cap cavity taper from the end web to the tip of the projecting portion.
