  • Patent number: 8893982
    Abstract: A rail support block assembly includes a resilient member and a molded block having a top, a bottom and peripheral wall. The block is adapted for fastening one or more rails on the top. The prefabricated resilient member has an outer tray and inner tray arranged within the outer tray, and includes a resilient intermediate structure between the trays. The block is molded in a block mold into with the moldable material is introduced and allowed to harden. The block is fixed in the inner tray to extend under the bottom of the block and along a lower region of the peripheral wall. The resilient member may form a part of the block mold, so that a mold member combined with the resilient member delimit the mold for the block. The moldable material is introduced and adheres directly to the inner tray of the prefabricated resilient member.

  • Patent number: 6471139
    Abstract: The invention relates to a rail arrangement for a rail superstucture such as a fixed railroad, comprising an elastic intermediate plate (3) which is located between the rail foot and a hard support (6) in the form of a concrete tie and has two through holes for the screws (7) to fasten the rails. For series mounting, which is the solution of choice, the elastic intermediate plate (3) is combined with an elastic intermediate layer (1) in such a way that the additional intermediate layer rests above the intermediate plate directly below the rail foot, whereby the intermediate layer (1) is separated from the intermediate plate (3) by a metal base plate (2) which serves to fasten the rail.

  • Patent number: 5082178
    Abstract: Mobile shelving apparatus comprises rails that are leveled by stacks of interlocking shims. The shims are placed under and interlock with rail support brackets at the joints in the rails. Rail spreaders used to align the rails are also leveled with and interlock with the shims. The mobile shelving apparatus includes a carriage platform supported on the rails by wheel assemblies that are assembled to the platform without fasteners. Wheels are retained to bearings by swaging portions of the wheels onto the bearing outer races. The bearing inner races are retained on respective shafts by swaging rings onto the shafts. The wheel assembly shafts are secured to the platform by swaging the ends of the shafts to the platform. The invention further comprises an upright anchor clip for joining the platform to the carriage framework that stores selected items.

  • Patent number: 4928602
    Abstract: A track clamp assembly for supporting or splicing tracks of I-shaped cross-section formed by a vertical web with horizontal parallel flanges at the opposite ends of the web and having a pair of oppositely facing grooves formed in the flanges on each side of the web. The track clamp assembly comprises upper and lower clamp members respectively having upper and lower edges insertable in a pair of track grooves, and having interengageable ramp surfaces disposed between the upper and lower edges and extending obliquely thereto. Outwardly projecting tabs on the clamp members are engageable by a connecting bolt which when tightened moves the ramp surfaces into interengagement, increasing the dimension between the upper and lower edges and forcing the clamp members into locking engagement with the track.

  • Patent number: 4473291
    Abstract: In a large, track mounted industrial camera or projector, a leveling arrangement for maintaining the track rails level when their support beams deflect under the influence of the weight of the camera and the rail mounted carriage which carries the camera toward a subject holder at one end of the track. Each rail is mounted on a rail base held down on the underlying support beam by a series of hold down screws. Adjustment screws are threaded through the rail bases and rest on the beams at their lower ends to control the distance of the rail bases above the beams. Each adjustment screw can be independently adjusted to compensate for beam deflection under actual loading conditions and for the variation in beam deflection along the length of the track. The overall track structure is stiffened to reduce beam deflection by an internal cable support structure secured to the rails and by a canopy secured to the beams.

  • Patent number: 4382547
    Abstract: A railroad plate and connectable shim are disclosed for fastening railroad tracks over ground having a flat or raised topography in an economically feasible manner. The instant system provides a base plate with a sloping grooved channel for reception of the lower flange of a rail to be held in place in combination with a trapezoidal shim to insure the proper cant of the rail over the various topographical areas of the country. The instant base plate, trapezoidal shim, rail and railroad tie are all fastened via a set of screws which are angled or toed-in towards the center of gravity of the rail. Stepped washers, each possessing a thickened portion, are provided between the bottom of the screw head and the upper shoulder surface of the lower flanges, both inside and outside the central vertical portion of the rail. The washers are omitted in securing back assemblies to the ties where joints are formed between the ends of adjacent rails.
