DOCK SHELTER WITH IMPROVED ADJUSTABLE HEAD PAD Abstract of the Disclosure A dock shelter having an improved adjustable head pad. The dock shelter borders a doorway in a dock wall and is adapted to be engaged by the rear end of a truck body to provide a weather seal around the doorway. The dock shelter includes a pair of vertical pads that extend along the sides of the doorway and a vertically adjustable head pad that extends horizontally across the upper end of the doorway. Cables are attached to the respective ends of the head pad and extend upwardly, are trained over a freely movable double pulley and are dead-ended on a fixed structure. The double pulley is connected through an extension spring to the support- ing structure, so that the force of the spring acts to urge the head pad upwardly and counterbalance the weight of the head pad. The counterbalancing mechanism insures precise vertical adjustment of the head pad and prevents racking or cocking of the head pad during adjustment.
