Patent number: 4234159Abstract: 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 outer end of the skid is connected to the tank with fasteners which do not require stress relieving of the tank body. The skid portion protects the lading valve closure and the lading valve seats against impacts which might normally cause unseating of the valve closure and escape of the lading in the absence of the skid portion.Type: GrantFiled: July 16, 1979Date of Patent: November 18, 1980Assignee: ACF Industries, IncorporatedInventors: Dallas W.

Patent number: 4158453Abstract: In accordance with the present invention, the bottom operable tank car valve assembly described in U.S. Pat. No. 3,981,481 is simplified and improved and a supplemental sealing arrangement is provided. In the improved design, the valve body includes a flange portion which is attached to a standard tank car universal flange and an inwardly extending circumferential portion upon which a valve closure seats in closed position. The valve closure includes a keeper which maintains a circumferential elastomeric seal in place engaging the closure. Clearance is provided between the closure operator, and the valve closure so that if the circumferential seal softens, melts or burns, the closure can move vertically downwardly relative to the closure operator, and the valve closure will engage the valve seat on the valve body in place of the circumferential seal, to substantially prevent escape of lading from the tank.Type: GrantFiled: September 19, 1977Date of Patent: June 19, 1979Assignee: ACF Industries, IncorporatedInventor: Charles E.
