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.

Abstract: A device for securely restraining cargo during transport, comprising a generally planar platform member supported in spaced relation from an underlying floor, and having an upper load bearing surface for receiving a cargo load thereupon, and an upright member being adjoined to one end of said platform member for effecting restraining contact with the adjacent side of the load seated on said platform member; said upright member including a generally planar member facing said load which is provided with a plurality of vertically spaced horizontal parallel slots therethrough, whereby straps may be passed beneath said platform member and then about the load seated thereupon and securely fastened in contact with said load by being passed through a horizontal slot at said upright member in accordance with the height of the said load seated on said platform member.
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.

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.
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.
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 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.
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).
