  • Patent number: 4892249
    Abstract: A railroad crossing is provided in which transverse and end panels are joined by means of splines fitted into indentations on side surfaces of said panels whereby pairs of panels are joined together with a spline fitting partly into each side or end of adjoining panels; and lateral anchor members for fixing the panels adjacent to said rails, the end panels and the outer field panels whereby the need is obviated for affixing the panels to the ties by means of surface spikes. In one embodiment an anchor is used which has vertical wall sections which project upwardly and have inwardly projecting horizontal lips and a spline retaining plate positioned beneath the lips. The spline rests on and is positioned transversely across said lips, and removable means are provided to fix the spline to the retaining plate.

  • Patent number: 4819566
    Abstract: A railroad vehicle is provided for movement on rails. The vehicle has a car body and two trucks. Each of the trucks has an outboard and an inboard axle mounted to the truck for pivotal movement about respective vertical axes such that the axles may be moved to a radial position when the vehicle is travelling on curved track. Each of the trucks has a pivotal connection, offset from center toward the outboard axle, between the truck and the car body. Each of the trucks contains a steering mechanism whereby the axles are moved to the radial position when the vehicle is travelling on curved track, with the alignment being obtained in response to the angle through which the truck swivels relative to the car body in traversing the curved track. The steerable trucks are stable provided that certain mathematical relationships set out are satisfied.

  • Patent number: 4817533
    Abstract: A transportation system of a floated-carrier type according to the present invention has a guide rail cover extending in a longitudinal direction. The guide rail cover comprises a guide rail. A carrier is made to float, in a non-contact manner, from the guide rail, by means of floating device and is propelled along the guide rail by a transfer device. An electrical device and a battery for supplying a current thereto are mounted on the carrier. In this transportation system, a charging device is provided for charging the battery. The charging device comprises a first terminal connected to the battery, a charging power source located on the guide rail cover, and a second terminal, which is connected to the charging electric power source and can be brought into contact with the first terminal when the carrier is stopped at a predetermined position.

  • Patent number: 4812113
    Abstract: Prestressed concrete railroad ties are formed in molds which are supported by existing track near the area where they are to be installed. Each mold will form a number of ties. Reinforcing strands are located within a plurality of longitudinally spaced molds. Concrete is then poured into the molds and the ties are formed bottoms up in the molds. A group of ties are simultaneously removed from a given mold by a special extractor which first simultaneously clamps the reinforcing strands extending outwardly from a given mold, and then lifts the strands as a group from the mold by a suitable crane. Preferably the center of gravity of ties is spaced from a pivot point which will cause rotation locating the ties in upright position to be loaded on a railway car or other vehicle to take them to the site where they are to be installed.

  • Patent number: 4811669
    Abstract: A portable drive for coaction with a band is provided with a motor driven drive roller for transporting the drive along the band. The drive roller with coacting structure for maintaining operative coaction with the band are settable to two main positions, viz, an operative and a neutral position, the band in the neutral position running freely while the drive roller with coacting structure being cantilevered so that the band can be freely taken aside for disengagement of the band from the drive, or for inserting the band from the side over the drive roller to coact therewith after resetting to the operative position. The inventive drive is primarily intended to be attachable to a skier allowing him to be towed up a hill along a band which is anchored at its upper end to a tree, for example.

  • Patent number: 4802419
    Abstract: An axle for a rail vehicle is pivotally connected to two equal length swinging arms, each of which is pivotally connected to the rail vehicle. The axle rotates about a virtual vertical axis away from the axle and nearer to the center of the rail vehicle. The axle is then radial for all curves over which a rail vehicle would usually traverse. In addition, the overhang of the rail vehicle while traversing a curve is reduced since the rail vehicle chords between virtual axes.

  • Patent number: 4799840
    Abstract: A cargo restraining device suitable for restraining barrel-shaped containers or drums is disclosed, which includes a platform, which is spaced from the underlying supporting surface or floor, by horizontal supporting members which extend the length of at least the flat portion of the platform, so as to provide a raised deck for the containers. At one end of the platform, an upright or vertical frame is connected to the supporting members, to prevent the containers from falling off the platform. The other end of the platform can be rounded over to define a snub-nose; or alternatively the other ends of the horizontal supporting members can project beyond the platform (which is otherwise flat) and be rounded into snub-nosed portions. In consequence, should the drums shift or move, whereby damage might ordinarily occur, the chimes or rims of the drums tend to flow around the snub-nose (or snub-noses if defined at the supporting members) without any significant damage.

  • Patent number: 4795093
    Abstract: A traction/sanding device for a wheeled vehicle provides a traction strip attached at one narrow edge to an inflated, breakable container filled with an abrasive substance. The traction strip defines a package wrapping container which protects the container prior to use, preferably in the form of a cardboard box which is unfolded to extend the traction strip. In use, the strip is placed at the intersection of the tire and the road surface, gripper tabs towards the tire. Tire movement, even if spinning, draws the strip under the tire, pulling the container underneath until the weight of the vehicle breaks the container, spilling the abrasive substance on the ground to give an area of improved traction.

  • Patent number: 4793577
    Abstract: The position of an event, such as emergency braking, of a railroad vehicle enroute on a track mapped on a chart is accurately recorded by continually sensing the degree and direction of track curvature, and recording the track curvature and event data for later display. Speed is also recorded as a function of time to provide a scale as an aid to interpolation of a recorded event position between recorded curves. The event position thus recorded and identified by nearby curves in the track is accurate to within a small fraction of a mile.

  • Patent number: 4792269
    Abstract: Container securing device that permits containers of any length to be carried by an integral or intermodal train including the feature of a container spanning the connection of two adjacent cores. The device is implemented in a two-part structure of an upper and a lower member. The lower member is adapted for fastening at any point along the car deck. The upper member has a pair of spaced corner members for receiving two corners of a container. An interconnecting means is arranged to connect the upper and lower members so that the upper member swivels with respect to the lower member and the car deck when the train rounds a curb and further provides for a longitudinal force dampening effect.

  • Patent number: 4790248
    Abstract: A dual coupling (1) comprises two elastic and articulated couplings (2 and 2a) interconnected by a hollow, intermediate shaft (3). Each one of the couplings (2,2a) contain an outer half (4,4a) with a hub (5,5a) from which extend several arms (6). Between them sit more arms (6a) of the intermediate shaft (3). With its arms (6a), the intermediate shaft represents the inner halves of the couplings (2,2a). The ends of the interacting arms (6 and 6a) are interconnected by rubber-elastic connecting rods (7) so that two rows (8) of arms are provided on bolts (10) to the left and right of the arms (6 and 6a) forming a joint plane. Therefore, two joint planes are present. While the connecting rods are connected to the bolts (10) in form closing fashion, the bolts are fixed or articulated in the arms (6 and 6a). One hub ( 5) is connected to a solid axle (15) and the other hub (5a) to a hollow shaft (18).
