Abstract
Abstract A shield assembly is disclosed in which a pair of shield members are pivoted in a bracket mounted on the trailer frame for movement between rearward and forward positions, the shield members normally being biased into the forward position by springs. In alternative arrangements purposed, the shield members are mounted on connecting rods biased forwardly in a cylinder or cylinders by coil springs.
