Filed:
Apr 7, 1986
Appl. No.:
6/848927
Inventors:
G. Gray Garland - Pittsburgh PA
Margaret G. Garland - Pittsburgh PA
Margaret G. Garland - Pittsburgh PA
International Classification:
E01F 702
US Classification:

Abstract:
A particulate material control apparatus is disclosed which includes longitudinally extending fin members attached at one end to a vertical post. The fin members are capable of rotating about the vertical post in an arc limited by adjacent posts or other stopping mechanisms. The fin members close against an adjacent post when wind or water currents flow across the area to be protected preventing wind or water erosion of sand, silt or soil in that area.
