    Abstract: A horizontal sliding door for a housing such as a cabinet. An axle rotatably mounted at the rear of the door projects into two identical tracks one at each side of the housing. Each track has a lower toothed rack and an upper stop surface facing the rack. A pinion slideably and non-rotatably mounted on each end of the axle engages the rack and is held there by an idler wheel slideably and rotatably mounted beside each pinion. A spacer sleeve near one end of the axle is removable, allowing one pinion and idler wheel to be slid inwardly, allowing removal of the door by passing that one end of the axle through a slot in one end of the track.

    Abstract: Apparatus is disclosed for use with an automatic closure of the type wherein the closure member, such as a door, returns to a home position when displaced therefrom. The closure member is at least partially supported by a hanger arm secured to a cam follower that rides on a cam track. The cam track forms part of a stationary structure which provides a bearing for a rotatable post. The post may carry further support means for the closure member.

    Abstract: An air seal is provided for restraining the flow of air through a cut-out section of a door which accommodates a door closing mechanism. A pair of nested cover strips individually flexed to a U-shaped configuration is mounted astride the mechanism, the bight of the outer strip resiliently abutting a vertical surface of the cut-out section in air sealing contact. The inner strip, which has greater resistance to flexing than the outer strip, contacts the side sections of the outer strip to stiffen them against flexing as the door is swung about its support. Both strips terminate in a fringed margin to accommodate the vertical rise of the lower boundary surface of the cut-out section as the door swings away from its closed position.

    Abstract: A DOOR OPERATOR ADAPTED TO MOVE AN UPWARDLY ACTING DOOR ALONG TRACKS BETWEEN OPEN AND CLOSED POSITIONS. THE OPERATOR INCLUDES A CARRIAGE MOUNTED UPON A SUBSTANTIALLY HORIZONTAL RAIL EXTENDING PERPENDICULARLY AWAY FROM THE CLOSED POSITION OF THE DOOR. AN ENDLESS CHAIN IS ARRANGED IN AN ELONGATED LOOP EXTENDING ALONG THE RAIL AND SUPPORTED FOR MOVEMENT RELATIVE THERETO. ONE END OF THE LOOP CAN ROTATE A SHAFT MOUNTED ABOVE THE CLOSED POSITION OF THE DOOR. CABLES ARE CONNECTED BETWEEN THE SHAFT AND THE LOWER EDGE OF THE DOOR. DRIVE MEANS ON THE CARRIAGE ENGAGES THE CHAIN AND CAUSES THE CARRIAGE TO MOVE RELATIVE TO THE CHAIN AND THE RAIL. LINKAGE CONNECTS THE CARRIAGE TO THE DOOR AND COOPERATES WITH THE CABLES FOR OPENING AND CLOSING THE DOOR.
