Abstract:
THE OUTLET OF A HOPPER HAS A ROTARY VALVE TUBE PROVIDED WITH AN ADAPTOR AT EACH END OF THE HOPPER. THE ADAPTOR HAS A BLUSHING IN WHICH TEH VALVE TUBE ROTATES, AND EACH ADAPTOR HAS AN EXTERNAL GROOVE IN WHICH AN END CLOSURE CAP MAY BE LOCKED. THE ROTARY TUBE HAS GROOVES IN WHICH THE COUPLER OF A MATERIAL DISCHARGE HOSE MAY BE LOCKED. SEALS ARE PROVIDED TO PREVENT AIR LEAKAGE WHEN EITHER THE END CAP OR THE DISCHARGE TUBE IS CONNECTED. THE COUPLER HAS HANDELS FOR ROTATING THE TUBE TO OPEN OR CLOSE THE VALVE.
Abstract:
A coupler positioning device for long length railway freight cars comprising an elastomeric member having an upper surface connected to the shank of a coupler for lateral movement therewith. The lower surface of the elastomeric member is operatively connected to the adjacent truck and moves with the truck upon a pivotal movement of the truck relative to the car body or center sill. The elastomeric member deflects in shear upon any relative lateral movement between the truck and the coupler shank. After the shear deflection of the elastomeric member the coupler shank and truck are urged by the bias of the elastomeric member to longitudinally aligned relation.
Abstract:
A lower generally pan-shaped cover for fitting around the entire bottom discharge structure of a railway hopper car, such as a discharge structure having a gravity gate and a combination rackand-pinion drive for the gravity gate. The cover seals the entire bottom outlet structure against the entrance of foreign matter including the drive means. Means mount the cover for movement between a covering position with respect to the bottom outlet and a position removed from beneath the bottom discharge outlet to permit the discharge of lading. The cover is formed of fiber glass and resin binder to insulate the bottom discharge structure for minimizing heat losses from an insulated car. The capstans for rotating the pinion shaft are mounted for folding to an inoperative position in order for the cover to cover the drive means while remaining within clearance limits and without being of an unduly long length.
