Abstract: A support including a rail (10) that preferably has an I-shaped section and is provided in a slot (2) filled with concrete (4). During the manufacture of the rail, the rail is partially coated, substantially along its entire length, with a filler material (8) which defines at least one side extension (16) and bears on the concrete. A side groove (9) is formed in the coating of filler material (8) for the passage of a guiding or rolling wheel. The rail is directly maintained by the concrete such that an intermediate device, for additional maintenance of the rail, is not required. The rail can be bent and curved at the time of installation to conform to the curves of the track without any independent or additional bending step.

Abstract: The invention is a hybrid wheel apparatus with a hybrid roadway apparatus that greatly reduces the energy lost due to rolling resistance where operation is on the hybrid roadway, but the system is configured to allow operation on conventional roads as needed. The hybrid wheel system is a steel wheel used in combination with a rubber tired wheel. The hybrid roadway is a low profile steel rail fixed to the otherwise conventional road surface, which is preferably concrete but could also be the very common asphalt composition. Where roadways are appropriately equipped with rails, the rail top surface is elevated over the roadway surface, and dimensions are set so that most of load force is carried on the steel wheel for general forward travel. Where the rail is absent the load is carried on the rubber tire, and the steel wheel is elevated above the roadway surface such that contact between the steel wheel and the roadway is prevented.

Abstract: Spindle device for the height adjustment and alignment of tracks on a substructure, having a transverse cantilever which is fixed to an elongate nut adjustable in height on a height adjustment spindle and which engages under the rail and which is formed as a horizontal spindle plate which is mounted on the elongate nut pivotably about a horizontal axis and on which a slide provided with a clamping mount device for the rail foot is displaceable by means of a second spindle device transverse to the height adjustment spindle.

Abstract: A rail cover and support for mounting and insulating the rails of an electric transit system in which the rail cover is vulcanized both to the rail and outer skid support at the manufacturing site prior to delivery to the field and a rail cover completely surrounds both the base flange and web portion of each rail and terminates along the undersides of the top flange. In one form, the upper free ends of the rail cover are increased in thickness to form bumpers along opposite sides of the rail to cushion it against undue shifting or vibration. In fabricating the rail, a sheet dielectric material is vulcanized to the rail with or without a skid plate.

Abstract: A rigid track consisting of concrete, in particular pre-cast components, comprising a slab with traversing fixing elements, or a plurality of fixing elements arranged thereon, of rails for track-borne vehicles. The inventive rigid track is characterized by a pre-cast concrete component constituting a protuberance that is positioned on the slab, parallel to at least one rail and located on at least one side of the rail. The protuberance acts as a guard and a guide for the vehicle during derailment.

Abstract: A railway crossing structure for a railway track including an elastomeric gauge insert (50) fitting between each rail (10) and the adjacent gauge panel (12). Elastomeric gauge insert (50) has a body portion (70) formed by upper and outer sides (72, 74) separated by an elasticity cavity (76) and joined to each other at juncture (78) defining an outer sealing surface (80). Hinge lines formed by notches (82, 84) in sides (72, 74) assist in the folding or flexing of body portion (70) as shown in FIG. 6 during installation of gauge insert (50) by a pushing force exerted against upper surface (62) of body (52). Body portion (70) snaps beneath head (16) of rail (10) upon the seating of gauge insert (50) with leg (54) engaging arcuate connecting surface (36) of base (18) as shown in FIG. 3. Sealing surface (80) of body portion (70) seals against undersurface (30) along a relatively large sealing area and a relatively large sealing force is provided by compressed sides (72, 74).

Abstract: A back-up guide for trucks or trailers is made of two elongated members attached perpendicularly to each other, with spikes on their underside to hold the device in a stationary position. The longer of the two members provides a guide for the side of a vehicle's rear wheel during backing up, and the other, shorter, member is laterally disposed and provides a wheel chock or stop member for the rear wheel, and also acts as a visual stop point for the driver. The lateral member has a rearward extension near each of its ends, which provides supports for wheels which allow easy movement of the device when the front end is raised to lift the spikes clear of the ground. Both members may be equipped with handles for ease of handling. The device may be transported by attachment to the side and back of a truck or trailer, resting on special brackets attached to the truck or trailer.

Abstract: A self steering vehicle for a transportation system including a roadway having a pair of elongated parallel tracks whose shape in cross-section is domed or convex and preferably having a pair of guide flanges positioned outwardly of the tracks, the vehicle having wheels provided with resilient track-engaging means, such as pneumatic tires, and driving means for propelling the vehicle over the roadway. The wheels of the vehicle tend to follow the tracks because of the deformation of the tires if they tend to move laterally off the center portions of the tracks, and the guide flanges engage the tires, upon the wheels having moved off the tracks because of the imposition of excessive side loads on the vehicle, to turn the wheels back onto the tracks.
