Fastenings Patents (Class 238/310)
  • Patent number: 10392754
    Abstract: A low maintenance rail seat has recess in the concrete tie and an abrasion plate that covers the floor of the recess and its sides parallel to the rail base. The abrasion plate includes ribs which seat in additional recesses in the tie to retard longitudinal movement. The anti-abrasion assembly preferably has four flanges which wrap around the top of concrete tie to prevent dust particles from entering and abrading the concrete rail seat. These flanges also wrap around the support shoulder for additional resistance to longitudinal movement. The components are designed to provide 8.5? of lateral support along the side of the rail base while the traditional e clip fastener provides only 3? of lateral support. The interlock feature between the anti-abrasion assembly and the concrete tie also minimizes relative movement between abrasion plate and concrete tie, which results in less concrete surface abrasion.

  • Patent number: 8181887
    Abstract: A device for positional securing and guiding of rails for railway tracks for trains, in particular high-speed trains, includes guide plates. In general, rails are laid directly or indirectly by intermediate assembly of intermediate plates to fixed concrete track beds and guide plates, against which the rail base and possibly intermediate plates lie laterally. Guide plates are embedded on or in the concrete track beds, wherein the guide plates are fabricated of high-strength, form-stable material, preferably reinforced plastic, such as for example glass-fiber reinforced plastic, in particular polyamide. The device according to the invention allows to create guide plates which are overall more wear resistant. Wear resistance is achieved in that the guide plate within the surface area, on which the rail base rests, has an insert or areas provided with inserts, the insert being fabricated of slippable, low-abrasion or friction-resistant, low-wear or wear-resistant and flexibly resilient material.

  • Patent number: 7389940
    Abstract: A method and a device for attaching an elevator guide rail to a substrate via a floating mount. The floating mount includes at least one of a base support, a side support, and a backside support. Each of the supports has a moveable part, a stop and a flexible element floatingly supporting the moveable part. Deforming forces cause the guide rail and the moveable part to move in a deforming direction deforming the flexible element until the deforming force exceeds a predetermined limit whereupon the stop limits further movement of the guide rail.

  • Patent number: 7374110
    Abstract: The present invention provides an isolator particularly adapted for use with a rail anchor utilized in an application where railroad rail is installed on concrete ties. The isolator protects the concrete tie from contact with the rail anchor caused by longitudinal movement of the rail due to train acceleration of deceleration or expansion and contraction due to temperature changes. In one embodiment, the isolator is comprised of a structural plastic material and includes a front face section and a rear face section. The front face section and rear face section each comprise a generally rectangular structure, having a top edge, bottom edge, and side edges. A center section joins the front face section and rear face section and forms part of the top of the isolator. In another embodiment, the front face section includes a top section and bottom section, with the top section having a lower edge projecting laterally at an acute angle from the bottom section.

  • Tie
    Publication number: 20040129792
    Abstract: Present invention concerns a tie being the carrying element for rails in a railway track. The tie comprises means (1) for fastening the rails to the tie which in use is lying in a ballast bed of crushed stone at the formation plane of the line. At the underside (2) the tie is provided with a number of elevations (4), whose height (H) is 40-100% of Dmax of the crushed stone. Each elevation (4) protrudes across the tie, and constitutes a cogging towards the crushed stone, in the longitudinal direction of the tie.

  • Patent number: 6758406
    Abstract: A brace assembly provides support to a railroad rail, such as for a switch. The rail is supported on a tie plate. A wedge block is secured to the tie plate adjacent the rail. A groove is located in the inner wall of the wedge block. The groove extends longitudinally between the side walls and is spaced between the upper and lower sides of the wedge block. A brace has a tapered upper edge and a tapered lower edge that engage the rail. The brace has a tongue that extends outward from the base into the groove. The tongue and groove have widths that decrease from one side to the other. Moving the brace longitudinally relative to the wedge block enables the brace to be wedged between the wedge block and the rail. A spring clip secures the brace to the wedge block.

  • Publication number: 20040084547
    Abstract: Concrete railroad ties are made having steel plates cast directly into the concrete railroad tie so that the top surface of each steel plate is even with the top surface of the concrete railroad tie. Fasteners for the rails can be welded to anywhere within the steel plate. Additionally, each steel plate can be cast into one of two different positions of the concrete railroad tie thus, creating more flexibility as to the positions of the rail fasteners on the railroad tie and reducing the length of the steel plate needed by half to three inches. By utilizing this assembly, the amount of concrete the patterns needed in a turnout is reduced.
