Abstract
A wheel chocking assembly that is especially suitable for securing a wide variety of automobiles to the deck of a railroad car includes a polyester strap member adapted to conform to the shape and extending over the top of an automobile's tire which is coupled to a pair of chock members formed as collapsible wedges and positioned in front of and behind the wheel. In one embodiment, the wedges are rotatably coupled to a pair of channels extending the length of the railroad car, and are collapsible for positioning of the automobiles during loading. Another embodiment utilizes a pair of wedges which are adjustably mounted in a telescopic fashion to frames extending inward from a channel attached to the deck of the railroad car at its sides, the channels being adapted to permit the frames to be swung up and out of the way during loading and unloading operations.
