Patent number: 4456220Abstract: In accordance with the present invention, an operating rod attached to a bottom outlet valve passes through a nozzle assembly connected to the tank top. The nozzle assembly includes a hollow cylindrical housing for the operating rod and means to seal the operating rod relative to the tank. The nozzle assembly further includes a sleeve made of a material having a coefficient of friction with metal, particularly steel. The material has sufficient shear strength to withstand loads applied by rotation of the operating rod to the nozzle assembly, and sufficient strength in compression to react bending moments applied to the nozzle assembly resulting from misalignment of the lading valve relative to the nozzle assembly. Preferably also the material is self lubricating to avoid potential failure of the material in the event the assembly is not regularly lubricated.Type: GrantFiled: June 1, 1981Date of Patent: June 26, 1984Assignee: ACF Industries, IncorporatedInventors: Gunter R. Behle, Joel A. Mingus

Patent number: 4447039Abstract: To provide a railway tank car mounting flange which does not extend more than one (1) inch below the tank bottom, fixed stops to prevent rotation of the valve closure during movement between open and closed positions, and fixed stops which determine the amount of travel of the valve closure between open and closed positions are located within the tank. The valve closure is provided with outwardly extending stops which engage the fixed stops within the tank. Preferably the fixed stops extend inwardly and upwardly from the mounting flange. Preferably the valve closure is bench assembled onto a removable valve seat and is installed into the tank from the bottom, avoiding the need for a workman to be located within the tank during installation.Type: GrantFiled: January 10, 1983Date of Patent: May 8, 1984Assignee: ACF Industries, IncorporatedInventor: Gunter R.

Patent number: 4440380Abstract: At least one ball valve segment is located within a partial valve cage mounted within a tank. The cage is integral with a valve housing removably mounted within a tank mounting flange. The housing includes an inclined sealing surface which the ball valve segment engages in closed position. A lading outlet chamber is located below the inclined sealing surface. An operating shaft is inclined with respect to the outlet chamber. Inclined openings are provided in the valve housing and in the outlet chamber through which the operating shaft passes. The operating shaft includes an eccentric head which is located within a non-round slot in the ball valve segment. Rotation of the operating shaft rotates the eccentric head which drives the valve segment between open and closed positions. Preferably a pair of ball valve segments located approximately 180.degree. apart are connected with supports or ribs. The valve segment which closes the opening into the discharge chamber is larger.Type: GrantFiled: April 28, 1982Date of Patent: April 3, 1984Assignee: ACF Industries, IncorporatedInventors: Gunter R.

Patent number: 4372025Abstract: An opening is formed in a tank bottom and a mounting flange for a bottom outlet valve is attached to the tank bottom extending into this opening. This valve mounting flange contains fastener openings. A vertically extending light source is removably attached to the mounting flange, for example with mechanical fasteners. This light source is shined upwardly into the tank and indicates a reference point on the internal surface of the tank top for locating a nozzle opening. This reference point is marked, and a top opening is then formed in the tank shell by workmen located in the tank, usually after rotating the tank 180.degree.. If the tank has been rotated prior to forming the top opening, the tank is again rotated 180.degree. to locate the top opening at the top of the tank. An optional reinforcing plate is then welded to the outside surface of the tank surrounding the top opening. This reinforcing plate contains a reinforcing plate opening.Type: GrantFiled: March 16, 1981Date of Patent: February 8, 1983Assignee: ACF Industries, IncorporatedInventor: Gunter R. Behle

Patent number: 4313591Abstract: A tank vehicle lading valve assembly is provided including a lading valve mounted in an opening in the bottom of the tank which is movable vertically between open and closed positions. A valve housing or outlet chamber including an unloading spout is attached below a tank bottom mounting flange with fasteners, which preferably define a shear plane. A first operator attached to an upper portion of the lading valve extends vertically up through the tank to the upper portion of the tank where it is adapted to receive a suitable handle or tool to move the lading valve between open and closed positions. A second operator is preferably attached to a lower portion of the lading valve. The second operator portion preferably extends at least partially through the valve housing. Thus the lading valve is operable from either the top of the tank or from the bottom of the tank. The first operator may be eliminated and the lading valve operated from the bottom.Type: GrantFiled: May 22, 1978Date of Patent: February 2, 1982Assignee: ACF Industries, IncorporatedInventors: Richard J.

Patent number: 4234158Abstract: 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 portion 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: 4161958Abstract: The present invention is directed to a fixture assembly for removing for repair and/or replacement some or all of the operating assembly of a bottom operable tank car valve while the closure portion of the valve, which closes the opening in the tank bottom, remains in closed position. The closure portion prevents lading from escaping from the tank while the damaged portion of the valve operating assembly is repaired and/or replaced, and the operating assembly is reassembled with a properly functioning valve operating assembly.Type: GrantFiled: August 1, 1977Date of Patent: July 24, 1979Assignee: ACF Industries, IncorporatedInventor: Gunter R.

Patent number: 4114636Abstract: An air inlet and outlet valve is located in the bottom of a tank so that the operator need not climb to the top of the tank to operate the valve. A conduit extends from the valve to the top of the tank. A stilling well is mounted inside the top of the tank. A ball which is lighter than the lading is mounted in the stilling well. The stilling well includes openings allowing air to enter or leave the tank through the conduit when the ball is in an unseated position in the stilling well. Lading contacting the ball moves the ball into a seated position which blocks the entrance to the conduit and prevents lading from entering the conduit, going down through the conduit to the valve at the bottom of the tank, and discharging from the conduit when the operator opens the valve.Type: GrantFiled: September 30, 1976Date of Patent: September 19, 1978Assignee: ACF Industries, IncorporatedInventor: Gunter R.
