Dirt and rock removal apparatus for vehicle tires

An apparatus for removing dirt and rocks from the tires of trucks and other vehicles, said apparatus comprising:

• a. a number of elongate, rigid metal ribs;
• b. first and second rigid plate sections;
• c. means for attaching said ribs to an upper surface of said first and second plate sections in a mutually parallel orientation transversely across said plate sections and in a longitudinally spaced-apart manner, the longitudinal spacing between the ribs, taken in conjunction with the height of the ribs relative to said surface, preventing the peripheral surface of a tire rolling over the apparatus in a longitudinal direction from contacting said mounting surface;
• and
• d. means for detachably connecting the first and second plate sections together in end to end relationship so as to form a large plate, said plates being connected so that all of said ribs attached to the first and second plate sections are mutually parallel, wherein said first and second plates are connected together, the composite plate formed thereby being about twelve feet long and about eight feet wide, and wherein the means for detachably connecting said first and second plate sections together includes a plurality of pins that extend through both of said ribs attached to the ends of said first and second plate sections.
