Abstract: A transporting system with a fire door (100) is provided with: a rail (1) installed within a facility; a transporting carriage (3), whose wheel (4) is set so as to roll over a surface for rolling of the rail; a fire door plate (7) for segmenting a space within the facility in a direction intersecting the rail at a predetermined position of the rail; and a door plate moving device (8) capable of moving the fire door plate from an open position for the transporting carriage to pass through the predetermined position, to a close position for the fire door plate to segment the space. A first cut (1a) is formed obliquely with respect to a width direction of the rail when planarly seen on the surface for rolling, in the rail at the predetermined position. The fire door plate has a shape capable of passing through the first cut when being moved to the close position.
Abstract: In a system comprising at least two conductor rails, in particular composite sections each featuring a rail-shaped load-bearing section and at least one strip-shaped section of another metal of greater wear resistance joined to the matrix of the load-bearing section, the ends of pairs of neighbouring rails are connected electrically by at least one conductor of variable length. The ends of the conductor rails are bent out of the central axis (M) of the conductor rail and led parallel to and a distance (n) displaced from that axis, such that the strip-shaped section of one conductor rail end is approximately aligned with the strip-shaped section of the other conductor rail away from the rail end; the conductor rail ends are joined in such a manner that they can move with respect to each other along the axial direction.
Abstract: The present invention involves a power saw for cutting railroad rails at an angle. The power saw includes a base, a cutting location disposed proximate the base, a cutting disc and associated driving mechanism, and a device for moving the cutting disc and changing the angle of the cutting disc relative to the cutting location. A table supports the cutting disc and driving mechanism, and the base has two pivots selectively engageable with the table. The driving mechanism of the cutting disc includes a cam based oscillating device for oscillating the cutting disc during cutting of a railroad rail. The power saw also includes a guide and a conveyor system for positioning a railroad rail on the cutting location. The conveyor system moves railroad rails to the guide. A device for applying force against the direction of the cutting force of the cutting disc is located at the cutting location. A device for delivering a fluid, a coolant, lubricant, or rust-inhibiting solution, is located adjacent to the cutting disc.
Abstract: A rail joint for interconnecting two successive rail bars of a railroad track includes longitudinally aligned first and second guide rails. Each of the guide rails has a mounting end adapted to be secured to a respective one of adjacent end portions of the rail bars, a distal end opposite to the mounting end and spaced from the distal end of the other one of the guide rails at an expansible space, and a downwardly and longitudinally extending dovetail projection. A connector is adapted to be fixed on the railroad track and is formed with an upwardly opening and longitudinally extending dovetail groove for receiving fittingly the dovetail projections of the guide rails therein so as to maintain alignment of the guide rails.
Abstract: A vehicle supporting guideway is presented, the guideway is comprised of upper horizontal stringers, lower horizontal stringers vertically oriented diagonal members affixed to the upper and lower horizontal stringers and horizontally oriented diagonal members are affixed between the lower horizontal stringers. These features present a guideway having an upwardly extending U-shape construction which can be supplied with wheel supporting channels, and upper support channels. The entire structure is reinforced by ribs which are generally within the horizontal stringers, and the entire guideway may be enclosed by a cover. Overlapping members join adjacent sections of the horizontal stringers together.
Abstract: This invention relates to an improvement in a frog for switches, in particular for rapid transit switches, with a junction rail mounted in a rotatable manner and adapted to close a gap between pairs of rails of straight or branch track, the improvement comprising that the two ends of the junction rail have the shape of an isosceles triangle and the corresponding ends of a transit rail taper on one side, whereby a continuous rail-head profile is formed when the junction rail abuts the transit rail.
Abstract: The specification describes an improved railroad track expansion joint which is comprised of a pair of longitudinally aligned elongated joint members interconnected with one another by means of a dovetail joint formed along abutting faces which extend at an acute angle to the members. The other ends of the joint members are connected to conventional rails and any expansion and contraction of the rails will cause the members to slide relative one another along the abutting face.
