Abstract: A panel clip for holding the side paneling of a rail car in place having a central channel-shaped portion the side walls of which at their extremities are bent laterally outwardly in opposite directions to provide coplanar flange portions. An integral tab is bent up from each flange portion at a right angle to the plane thereof.

Abstract: An end closure for a rail car which comprises a pair of doors mounted for lateral movement from a closed position across the major lower portion of the opening in one end of the rail car to an open position. A panel is mounted above each door for lateral movement from a closed position across an upper portion of the opening in the end of the rail car to an open position. Each panel is connected to the door beneath it to cause the panel to be moved to open and closed positions by the corresponding movement of the door.

Abstract: An end closure for a rail car which comprises a pair of sliding doors mounted for movement between open and closed positions. One of the doors has a recess to clear a brake lever when the door is open. A panel is provided to close the recess when the door is closed. The panel is automatically moved to a position opening the recess when the door is opened and automatically moved to a position closing the recess when the door is closed.

Abstract: A hook structure which forms part of a device for tying down motor vehicles upon vehicle transports such as railroad cars, trailers, and the like. The hook structure is capable of being inserted through an elongated slot in the frame of a motor vehicle and comprises a body having means at opposite edges for the attachment of two chains. A bolt is rotatably connected to the body and terminates in an elongated cross-head. The bolt is capable of being inserted head first into the slot and retained therein when turned 90.degree.. The bolt has a square shank portion under the head which normally engages the slot to prevent rotation. The bolt shank has a circular portion more remote from the head to permit the bolt to be rotated when inserted farther into the slot.

Abstract: A device for adjusting the length of a link chain comprising a shackle or yoke in which the space between the arms is relatively wide except for a narrow portion at the closed end of the shackle. A length of chain extends through the space between the arms and is capable of moving lengthwise when in the relatively wide portion of the space. The relatively narrow portion of the space is wide enough to receive a link of the chain but not wide enough to permit the chain to move in a lengthwise direction. A pivoted keeper is adapted to project into the relatively wide portion of the space to retain the chain in the narrow portion and thereby prevent it from moving lengthwise.

Abstract: An end closure for a rail car which comprises a pair of sliding doors. Locking mechanisms provided for securing the doors in closed position extending across the end of the rail car as well as in open and in intermediate positions. Each door moves from closed to open position through an opening in the side wall of the rail car to an open space on the outer side of the side wall within the allowed rail car clearance.
