A dirt runner, such as those used on street sweeping machines and the like, and a flexible support for the dirt runner to be attached to a housing portion. Flexible supports such as elongate strips of elastomeric material are fastened along the upper portion of the strips to the housing portion of the machine and the dirt runner is fastened along the lower portion of the elastomeric strip. The dirt runner is adequately supported to be driven in its longitudinal direction of travel and more freely flexible in lateral directions to its direction of travel. The dirt runner is uniquely designed to accommodate the additional feature of the flexible means such that the dirt runner and flexible means may be substituted directly to the existing street sweeper machines without modification thereof.

Dirt runner and support therefor

An earthworking blade arrangement, such as for a grader or snow plow blade or the like, in which a steel blade is mounted on the lower edge of a moldboard and extends downwardly therefrom while an axially segmented blade is secured to the lower edge of the steel blade and extends downwardly therefrom and is provided with hard wear resistant inserts mounted in the lower edge thereof and which forms the working edge of the blade assembly. Advantageously, the axially segmented member extends a substantial distance upwardly along the back of the steel blade and is bolted thereto.
