  • Patent number: 6508180
    Abstract: A method for positioning railroad freight cars at specified positions while using robust positioning devices. One end of a train is prepositioned inside a comparatively wide area and a buffer device is activated. The locomotive pulls the train in a direction of travel until the activated buffer engages with a counter-buffer. The locomotive then exerts an additional tractive force so that the train is lengthened, whereby the front end of the first car, thus of the car coupled to the locomotive, is arranged in the area of a second counter-buffer device. A second buffer device is subsequently activated in a similar manner. The locomotive now decreases the tractive force so that the train is drawn together and so that the second buffer engages the second counter-buffer. The described positioning can be effected in the same manner by applying a pressure pretension onto the train.

Once the projecting member has been lowered into the cavity, the wheels automatically unfold, so that they assume horizontal positions and press against opposing sidewalls of the cavity. With the wheels so deployed, the vehicle can be safely driven during high speed cornering and under windy conditions. The wheels can also be used to automatically steer each vehicle. In addition, the wheels are used to conduct electricity in the cavity sidewalls as part of the power takeoff for an electric vehicle.

  • Patent number: 5738017
    Abstract: A rail vehicle has a pivotal latch pivotally mounted to its frame so that gravity urges one end of the locking latch toward a rack extending along the railway on which the rail vehicle is positioned for movement. A smooth slideway extends parallel to and adjacent the rack and a rocker arm pivotally mounted on the locking latch has a lower end pivotally urged by gravity into contact with the slideway so that forward movement of the rail vehicle pivots the rocking arm to cause the locking latch to be pivoted upwardly out of contact with the rack with any initiation of rearward movement causing reverse pivoting of the rocker arm to lower the locking latch into engagement with the rack to prevent further reverse movement of the vehicle. Maintaining the locking latch out of contact with the rack during forward movement reduces wear and avoids the generation of clacking noise during forward movement of the vehicle.

  • Patent number: 5715756
    Abstract: An amusement ride attraction has an anti-roll back track with stops or cross bolts covered by a continuous brush material. A vehicle such as a roller coaster car or water flume boat has an anti-roll back pawl which rides above the fiber material on skis, when the vehicle moves forward. If the vehicle begins to move backward, the skis move downwardly through the brush material and the pawl engages a stop on the track, to prevent further reverse movement. The brush material prevents the pawl from banging over each of the stops on the track, thereby reducing noise and wear.

  • Patent number: 5636575
    Abstract: A retarder apparatus controls the speed of a free, load-carrying conveyor as it moves in a predetermined direction along a path of travel defined by the track in which the conveyor runs. Paddle members are spaced at regular intervals along an endless movable chain and each, in turn, is positioned in the track in the path of the next conveyor. Upon engagement of an individual paddle by an oncoming conveyor, the chain is instantly accelerated to the speed of the conveyor and this motion is transmitted through a chain sprocket to a centrifugal brake which, if a normal speed is being exceeded, limits the speed of movement of the chain to hold back a runaway conveyor and return it to the normal speed.

  • Patent number: RE36084
    Abstract: A brake apparatus that is designed to brake a drag race vehicle that is movable within a track of an amusement ride. The braking apparatus includes a pair of braking units that each include movable portions that are movable toward each other so as to clamp onto a guide plate that is being carried by the vehicle as it moves along the track. This clamping onto the guide plate results in slowing and eventual slopping of the vehicle. The braking units are movable by means of inflatable bladders into the braking position. The braking units are mounted on metallic cross beams which are fixedly mounted to the track The movable portions of the braking units are slidably mounted on the metallic cross beams. Longitudinal movement of the movable portions, which occurs during the braking position, is to evenly apply pressure against each of the metallic cross beams. Each of the bring units are continuously spring biased toward the non-braking position.
