Abstract: A trailer bunk cover assembly designed to not only protect boat hulls during launching and loading from the trailer, but also to protect the trailer's bunks from becoming worn down with use. The bunk cover assembly includes a main body portion having an upper surface and a lower surface. When mounted to the trailer bunk, the lower surface of the main body portion is in contact with the top surface of the trailer bunk. When a boat is loaded on the boat trailer, the hull of the boat rests on the upper surface of the main body portion. The cover assembly further includes first and second side panels that extend downward from the main body portion. The side panels cooperate to help position the main body portion against the top surface of the trailer bunk. The side panels respectively include a plurality of apertures. Attachment screws that act as a securing means to hold the cover assembly in place on the top surface of the trailer bunk.

Abstract: A coke oven door extractor is mounted on the rail car and includes door engaging supports movable in individually differing amounts relative to a plane parallel to and including the door jamb and a door jamb height axis of symmetry and movable vertically, allowing the door extractor to compensate for front-to-back tilting and side-to-side leaning of the coke oven door jamb due to thermal distortion of the battery and variations in individual door heights. The extractor includes a first frame pivotally mounted to the car, a second frame horizontally translatably mounted to the first frame, and a third frame vertically translatably and pivotally mounted to the second frame, with the third frame including the door supports.
