Patent number: 8763536Abstract: Disclosed is a truck lateral motion restricting device which can prevent a large impact from being applied to a stopper when the truck lateral motion restricting device is operated in the derailment. The device comprises a guard angle (52) which is provided along the inside of the rail (51) and a stopper (25) which projects downward from a more inward position than wheels (15) of the truck (11) and is in slidable contact with the inside surface (52a) of the guard angle, wherein the stopper comprises a slidable contact portion (28), which has a slidable contact surface slidable contact with the inside surface of the guard angle, and guide portions (31) which project at front and rear portions of the slidable contact portion and have a front end inclined in a direction separating from the inside surface of the guard angle and a base having a guide slope (31a) provided continuously to the slidable contact surface.Type: GrantFiled: April 22, 2010Date of Patent: July 1, 2014Assignees: Central Japan Railway Company, Nippon Sharyo, Ltd.Inventors: Kei Sakanoue, Yoshinori Minami, Masahito Adachi, Hironobu Sunami, Nobuhisa Takada, Toru Konokawa

Patent number: 8261671Abstract: A bogie lateral movement-limiting system capable of effectively restricting the lateral movement of a derailed bogie. The system comprises derailment prevention guards (62a, 62b) laid along the inside of paired left and right rails, and a lateral movement-limiting device (52) installed on the lower part of the bogie (30). The device (52) has a stopper (51) projecting downward at a position between the wheels of the bogie and slidingly contacts with the inner surfaces of the derailment prevention guards (62a, 62b) in case of a derailment of bogie.Type: GrantFiled: March 12, 2007Date of Patent: September 11, 2012Assignees: Central Japan Railway Company, Nippon Sharyo, Ltd.Inventors: Kei Sakanoue, Yoshinori Minami, Toshiki Kunii, Nobuhisa Takada

Patent number: 5619930Abstract: A transportation system for transporting vehicles between destinations, including a self-supporting tunnel connecting automated loading and unloading yards, and a non-wheeled tubular vehicle including a ram drive. The vehicle is provided with anti-friction pads between the vehicle and the tunnel, enabling the vehicle to be pushed with a minimum of friction through the tunnel. The pads include an expansion and contraction mechanism for regulating the position of the pads relative to an inner surface of the tunnel. The system uses a jet-powered drive vehicle controlled by an operator to transport a plurality of vehicles interconnected by a coupling apparatus. The vehicles may transport automobiles or passengers. The automobile transport vehicles include an automatic wheel locking system having front bars and caps, all automatically operated to secure the vehicles in the capsules during transportation thereof.Type: GrantFiled: December 8, 1995Date of Patent: April 15, 1997Inventor: Constantin Alimanestiano

Patent number: 5226367Abstract: A railway loading dock is provided with adjacent trackage having pairs of main rails and stabilizing rails. A modified railway flatbed car is equipped along its sides with stabilizing wheels and associated support structure to retain the car bed coplanar with the loading dock surface to permit drive on loading and drive off unloading of large trucks. The railway car bed is equipped with bed extensions which primarily occupy that space between ends of adjacent cars to permit travel of trucks, in a straight or oblique manner, over the ends of adjacent railway cars. The stabilizing rails have inclined segments for gradual engagement with the car stabilizing wheels.Type: GrantFiled: August 17, 1992Date of Patent: July 13, 1993Inventor: Eric R. McLaughlin

Patent number: 5188038Abstract: The present invention features a safety device that activates the air-brake system immediately upon the detection and/or occurrence of a railroad car derailment condition. The safety device includes a bar entension disposed beneath each car of a train. The extension bar is disposed transverse to the parallel rails and is positioned a few (approximately four) inches above them. When any one of the cars is caused to derail, the extension bar contacts the rail, causing a trip valve in the air-brake line to open. The opening of the trip valve gradually releases the air pressure in the line, thus automatically and instantaneously actuating the air-brake system throughout the train. The gradual release of the air pressure in the air-brake system provides more time for the engineer of the train to bring the train under control and reduces the possibility of damage and injury caused by the derailment.Type: GrantFiled: March 9, 1992Date of Patent: February 23, 1993Inventor: Thomas E. Shanley

Patent number: 4785739Abstract: In a tracked transportation system independent cars are drawn along by a common cable. A car comprises a rolling chassis with a cabin suspended above the chassis by a set of chains. The chains are coupled to a shaft forming apparatus for weighing the cabin and connected to an assembly for gripping the cable. The coupling between the chains and the gripping assembly can be released by a trigger device fixed to the track and operated by remote control to lower the cabin relative to the chassis and so achieve emergency braking.Type: GrantFiled: November 4, 1986Date of Patent: November 22, 1988Assignee: SouleInventor: Jean Huon de Kermadec

Patent number: 4339997Abstract: A railroad car is equipped with air release means in air flow communication with the car train pipe that is normally provided for connection with the air brake train line of a railroad train. Activators for the air release means are associated with respective sets of wheels, at opposite sides of respective wheel trucks of the car and at a height which will clear the corresponding rails of the railroad track during their travel but in positions to engage such rails upon derailment of any corresponding car wheel for operating the air release means, whereby the brakes of the train will be applied automatically upon any derailment. A novel air release valve with activator is preferably employed at respective opposite sides of respective wheel trucks as the air release means.Type: GrantFiled: June 28, 1980Date of Patent: July 20, 1982Inventor: David T. Chiles

Patent number: 4269288Abstract: Downwardly depending contact members are secured to the undercarriage of railroad cars and positioned inboard from the wheels of the cars and also positioned above the level at which the wheels contact the underlying tracks. These contact members are upwardly displaceable when the train derails upon contact with a rail or ground debris to release fluid pressure in the train brake system and thereby activate the brakes of all of the cars.Type: GrantFiled: May 11, 1979Date of Patent: May 26, 1981Inventor: Joseph A. Collins

Patent number: 4062295Abstract: An emergency slipper of the type usually spaced above a track but which comes into sliding engagement with the track in an emergency. The slipper comprises slide blocks having bottom surfaces which slide easily along the track, and scraper means for scraping rust, dirt, ice, and the like for the track. The scraper means may be a vertical scraper plate arranged diagonally with respect to the direction of travel, the slipper having a diagonal groove directly in front of the scraper plate. The scraper means may be a scrubbing block arranged as the first slide block of the slipper, the scrubbing block being formed of an impact and abrasion resistant material with a low coefficient of friction and high resistance to high temperatures produced by friction. The rear block of the slipper may be formed of the same material as the scrubbing block. The scrubbing block may have a diagonal groove in its bottom surface. The front block may have an inclined surface between its front and bottom faces.Type: GrantFiled: August 2, 1976Date of Patent: December 13, 1977Assignee: Maschinenfabrik Augsburg-Nurnberg AktiengesellschaftInventor: Lutz Hamann
