Abstract
Abstract The front end of this file cabinet is closed by a door which is hinged at its upper end to the cabinet. The door may be swung upwardly and forwardly about its pivot to horizontal position and then pushed back into the top of the cabinet to keep the cabinet open at the front. Door pivot blocks are fixed at the outer ends of the upper end of the door. At the inner sides of the upper ends of the side walls of the cabinet, are fixed horizontal racks with upwardly facing teeth. The door pivot blocks carry horizontally aligned pivot pins journalled on rack slides, slidably mounted on rack carriers fixed to the side walls of the cabinet and supporting the racks. Rotatably mounted on the rack slides is a transverse shaft, to the ends of which are fixed gears meshing with the racks.
