摘要： A coupler-centering devices includes a rack on the bottom of the coupler shank having longitudinal gear teeth so that lateral movement of the coupler causes rotation of a gear segment. The gear segment is adjustably spring mounted and is connected to a torsion rod through a hand-operated clutch. The torsion rod extends parallel to the centerline of the car immediately below the coupler shank, and its inner end is fixed to the car. Alternatively, the rod may serve as a shaft to turn a torsional rubber shear structure. The teeth of the rack are long enough to permit buff and draft movement of the coupler.

摘要： A bottom outlet for tanks is provided including a valve body welded to an opening in the bottom of the tank. The valve body has an opening into which a retainer assembly is fitted to urge a seal into engagement with at least a portion of the valve body. The retainer assembly includes a threaded center portion and a retainer vertical portion having an opening therein. A valve plug is mounted to be vertically movable between closed and open positions, into and out of engagement with the retainer vertical portion. A lower housing is affixed to the valve body with mechanical fasteners which define a first shear plane. The housing has an opening into which a valve operator assembly is mounted. The valve operator assembly includes a first valve operator having a lower tool connection and a first operator extension. The first operator extension has a first valve operator opening into which a second valve operator is inserted and is drivably engaged. The second valve operator includes a second shear plane and has threads which engage the threads in the threaded center portion of the retainer assembly. These threads may define the second shear plane. The second valve operator engages the valve plug, and moves the same between closed and open positions. A seal member is affixed to the valve plug or to the retainer vertical portion.

摘要： In a bottom operable tank car lading valve assembly, a combination skid and lading valve seat for the lading valve closure is provided, which is attached to the tank car universal flange with mechanical fasteners. The valve seat portion extends inwardly and upwardly from the universal flange and includes a machined seat. The skid portion extends upwardly and outwardly from the universal flange, forming a circumferential taper, and the upper portion abuts the bottom of the tank. The skid portion protects the lading valve closure and the lading valve seat against impacts which might normally cause unseating of the valve closure and escape of the lading in the absence of the skid portion.
