Patent number: 5579698Abstract: An apparatus specifically tailored to transporting pipes in a tunnel is disclosed. A pair of low slung bogies are used to support and transport a pipe to pipe junction location. The bogies move over a pair of rails on rollers. The pipe rests on a set of inflatable devices which may be selectively inflated in a controlled manner to move the pipe in two axes during transport to the junction site. At the junction site, the inflatable devices are used to "jockey" the pipe on the transport device to provide limited roll, pitch and yaw movement of the pipe to facilitate mating the transported pipe with the end of a previously set pipe string.Type: GrantFiled: November 27, 1995Date of Patent: December 3, 1996Inventors: Henry Lis, Michael P. McNally

Patent number: 5431110Abstract: A truck-train system that provides for the mounting and dismounting of a truck-trailer on/from a railway dolly at any stretch of train rails which is paved or gravelled level to the height of the rail head, and employing a moment arm reaction locking mechanism that automatically centers and engages the truck-trailer thereby locking it into place. The dolly includes a steering rod assembly that permits it to steer into curves in either direction of operation. Also included on the dolly, is a truck assembly that utilizes a floating pedestal. The moment arm reaction locking mechanism coupled with the steering rod assembly and the floating pedestal affords greater lateral stability and greatly increased operating speeds of the truck-train system.Type: GrantFiled: April 28, 1994Date of Patent: July 11, 1995Inventor: George W. Adams, Jr.

Patent number: 5295442Abstract: A multiple track rail transportation system provides cars having a greater than standard width to span adjacent parallel tracks, and apparatus providing for such cars to ride on standard wheel trucks on each of the parallel tracks. Laterally spaced apart and coupled conventional engines may be used to pull such cars, and interconnection between the laterally spaced apart locomotives is provided to enable the train to be operated by a single crew in the cab of one locomotive. Alternatively, a single locomotive spanning the two adjacent parallel tracks may be used. Couplings are provided to enable conventional cars to be coupled to the wider cars and/or engine as needed. The system provides gains in efficiency over relatively narrow trains limited by a single track, allowing shorter trains to still carry the same amount of cargo and/or passengers, and moreover allows wider loads to be carried without disassembly or transfer to smaller cars.Type: GrantFiled: April 1, 1993Date of Patent: March 22, 1994Inventor: Jack H. Carpenter

Patent number: 4947760Abstract: An articulated railroad flat car for single-level loading of containers has five units or platforms. End trucks are disposed at the ends of the two end units and four shared trucks are disposed intermediate the five units at articulated connections between the units. Each unit has a center sill with bolsters at either end mounting outer container retention devices. Alternate units further include intermediate cross-bearers, with intermediate container retention devices mounted on the cross-bearer. This arrangement allows loading of full length containers (40, 45 or 48 feet in length) on each unit and either full length or 20 foot containers on alternative units. A container floor safety system includes a plurality of cross-ties connected to the center sill with longitudinal stringers fastened to the outer ends of the cross-ties. The container floor safety system prevents container lading from falling to the track in the event of a container floor failure.Type: GrantFiled: August 15, 1989Date of Patent: August 14, 1990Assignee: Trailer Train CompanyInventors: Richard W.

Patent number: 4381713Abstract: An air control system is provided for a vehicle convertible between highway and railway modes of travel. Air springs suspend a rail-wheel set axle unit and highway wheel-set axle units from the vehicle body so that the one wheel-set axle unit is stored in a raised inoperative position while the other is in the lowered operative position. During a transfer from the highway mode of travel to the railroad mode of travel, or vice-versa, a valved air control system selectively allows the wheel-set axle units to be positioned in either the raised or lowered positions. The air control system also includes, in addition to the mode selection function, the highway braking function, the rail braking function, the parking brake and the emergency brake functions.Type: GrantFiled: September 25, 1981Date of Patent: May 3, 1983Assignee: Bi-Modal CorporationInventor: Christopher A.

Patent number: 4364315Abstract: A convertible rail-highway vehicle having a semi-trailer with a truck provided adjacent the rear of the trailer with connecting structure for pivotally connecting the truck to a central beam for movement about a vertical axis. The truck has at least a pair of spaced and parallel axles for carrying at opposite ends thereof a pair of flanged wheels and a pair of highway wheels. The axes of rotation of the highway wheels are radially offset from the axes of rotation of flanged wheels. The axles are each rotatably supported in a pair of elongated and parallel bars which are, in turn, pivotally supported from a laterally extending support member on the truck. A releasable connection is provided adjacent the front end of the trailer for facilitating a selective connection to a highway tractor and to a further truck.Type: GrantFiled: August 29, 1980Date of Patent: December 21, 1982Assignee: Rail-Or-Trail Corp.Inventor: William T.

Patent number: 4357878Abstract: A load distribution system for railway cars, in which the load is applied to the supporting structure by fixed bearing arrangements, at one pair of longitudinally spaced points, at one side of the center line of the structure and is applied to the supporting structure at another pair of correspondingly longitudinally spaced points at the other side of the center line of the structure, and aligned with the first pair of points by a pair of hydraulic cylinders which are connected to each other in a closed hydraulic system. In effect my arrangement converts a statistically indeterminate four point suspension to a statistically determinant three point suspension.Type: GrantFiled: February 7, 1980Date of Patent: November 9, 1982Assignee: Norca CorporationInventor: Franco Fedele

Patent number: 4341494Abstract: A reduced-pivot assembly for supporting one end of a load for movement along a track in which a load support member for receiving that end is supported on a truck for lateral movement relative to the way. A limit switch mounted along the longitudinal center line of the truck at a location corresponding to a desired pivot center spaced from the load support center senses the lateral deviation of an adjacent portion of the load support member and actuates lateral shifting apparatus to shift the load support member in such a direction as to achieve the desired pivot center. A plurality of such sensors are disposed at longitudinally spaced locations on the truck to permit variation of the desired pivot center while moving along a track. Other sensors responsive to the lateral movement of the load support member inhibit the operation of the lateral shifting apparatus whenever the lateral displacement of the load support member exceeds a predetermined safe limit.Type: GrantFiled: February 13, 1980Date of Patent: July 27, 1982Assignee: Norca CorporationInventor: Franco Fedele
