Abstract
A wear protected belt comprising an elongated, generally flexible belt having a plurality of plates attached to the face of the belt. The plates extend across the belt at an angle to its longitudinal axis, and substantially cover a longitudinal portion of the belt. Each plate has a first plate portion, or rib, which projects laterally from the face of the belt. Attached to the rib is a second plate portion, or top which projects from the rib and extends over a portion of the belt parallel but spaced from the face of the belt. Disposed between the top of the plate and the belt surface is a shock absorbing bar means, or bar. When heavy objects impact the top of the plate, the top of the plate engages the bar and the bar absorbs the force of the impact. The bar also resists shearing or bending forces on the plate by bearing against the top of the plate and thereby resisting turning motions on the plate.
