Abstract: This invention relates to hinged derail assemblies used in the railroad industry for derailing a wheel of an undesirably moving railed vehicle. The hinged derail assembly includes a base that is positioned adjacent one rail of a pair of railroad rails. A derail shoe is pivotally mounted on the derail base and is moveable between a derailing position and an inoperative position. In the present invention a biasing member, such as a torsion spring, is secured to both the base of the hinged derail assembly and the derail shoe. The spring provides upward lifting force whether the derail shoe is in the inoperative position or in the derailing position. This lifting force assists the worker in the manual lifting of the derail shoe. The invention also relates to a method of constructing the hinged derail wherein the torsion spring is installed when the derail shoe is generally upright.

Abstract: This invention relates to hinged derail assemblies used in the railroad industry as a safety device for derailing a wheel of an undesirably moving railed vehicle, such as a railroad freight car. The hinged derail assembly includes a base that is rigidly mounted on a pair of spaced railroad ties and is operatively positioned adjacent one rail of a pair of conventional railroad rails. A derail shoe is pivotally mounted on the derail base and is moveable between an operative or derailing position and an inoperative position when the derail shoe is moved away from the rail. When the derail shoe is on the rail, a deflecting member on the shoe is positioned to angularly deflect a wheel of the freight car or the like which is undesirably rolling along the rail. This causes the derailing of the wheeled vehicle and prevents harm to things or personnel in the area.

The retarder includes a hydraulic unit having a portion adapted to be deflected out of the path of a wheel of the wagon when directly or indirectly engaged by the wheel before returning to its original position. The unit has adjustable hydraulic damping capable of resisting such deflection to retard the wagon, and a wagon speed responder for adjusting the hydraulic damping of the unit to retard a wagon travelling at high speed.

Abstract: A low-profile railway car retarder having a pair of braking bars disposed parallel and on opposite sides of a track rail and having an upper and lower pivotal lever carrying a respective one of the pairs of braking bars. A pneumatic motor pivotally connected to the outer extremities of the upper and lower levers, and the height of the pivotal connection of the upper lever is substantially at the same level as the track rail so that a humped railway vehicle is permitted to freely pass through the car retarder. The pneumatic motor lifts the upper lever and depresses the lower lever to move the pair of braking bars to a closed braking position wherein pressure is supplied to the pneumatic motor so that the pair of braking bars engage the opposite side of the wheels of a traversing vehicle at a relatively high point to exert a greater amount of retardation of the vehicle.

Abstract: This invention relates to the design of marshalling yard with up-grade speed control system. The principal difference between this yard and the conventional marshalling yard with down-grade only profile is described hereunder. Unlike the already known yard in which many speed control devices are installed on a down-grade to consume excess energy of cuts, the yard in the invention has hump height designed by taking operating conditions of moderate runners as a base and is provided with at least one up-grade speed control unit consisting of one up-grade section and a necessary number of boosters and retarders on the down-grade profile. This up-grade control unit could convert excess energy of cuts into potential energy. The invention could raise hump operating capacity of marshalling yard at a considerably reduced cost.

Abstract: A retarder, suitable when mounted in association with a rail of a railway track for reducing the speed of a wagon rolling along the track, includes an hydraulic unit which comprises a hollow member, a piston slidably housed in that member, and a piston rod. A portion of the hydraulic unit is, for retardation of the wagon, disposed in the path of a wagon wheel. When that portion is engaged, directly or indirectly, by a wheel it is deflected by, and out of the path of, the wheel to permit the wheel to pass the retarder. The ratio of the diameter of the piston to the diameter of the piston rod is in the range 2.80:1 to 6.00:1 and the ratio of the diameter of the piston to the length of stroke of the hydraulic unit is in the range 0.53:1 to 1.20:1.

Abstract: A retarder, suitable for mounting with respect to a rail of a railway track for reducing the speed of a wagon rolling along the track, includes an hydraulic unit a portion of which, for retardation of the wagon, is disposed in the path of a wheel of the wagon. That portion when engaged, directly or indirectly, by the wheel is deflected by, and out of the path of, the wheel. A thruster device, disposed alongside the unit and capable also of deflecting the portion out of the path, includes a displaceable element which is normally disengaged from the portion but which upon initial movement thereof is so tilted that a part thereof comes into driving engagement with the portion. On continued movement of the element the driving engagement is maintained and the portion moves from its position in the path of the wheel into another position out of the path.

Abstract: An electric rerailer provided with guide ways for guiding a motor-driven vehicle of a model railway onto a pair of rails, in which the surfaces of the guide ways are formed by electric conductors electrically isolated from each other and used respectively for the left and right wheels of the vehicle, and the conductors are capable of being electrically contacted with the rails for the left and right wheels respectively. The guide ways are formed on inclined or horizontal surfaces of the rerailer base, and the rerailer base is capable of being releasably mounted on the rails or being connected between ends of the rails.

Abstract: Apparatus for rerailing derailed wheels of a railway vehicle includes a bridge which is positioned beneath a derailed vehicle end. After the vehicle is leveled, a lifting jack disposed on a carriage mounted on the bridge supportingly elevates the derailed vehicle end and moves the supported derailed end over the rails, the bridge being positioned to return the derailed vehicles to a position over the rails. Since the wheels of the opposed vehicle end are stationary, the derailed vehicle end is moved along an arcuate path. A motive means such as a jack moves the carriage along the bridge axis, and supporting roller means on the carriage enable the lifting jack engaging the vehicle to move transversely to the bridge axis thereby allowing the jack and supported vehicle end to traverse an arcuate path while fully supported.
