Vertical Wedge-operated Patents (Class 238/334)
  • Patent number: 6138921
    Abstract: A rail-to-wood sleeper fastening mechanism in railroads, consisted of a clamp having an upper and middle branch fixed to the lower face of a sleeper, and with a pair of lateral and hinged branches, constituting the clamp, going through the sleeper via chimneys, and presenting upper and bent ends, sliding on the upper face of a foot of a rail, when respective wedges are inserted into said chimneys, that can be optionally configured by establishing a hinged union which is removable between the side branches of the clamp and its lower and middle branch, so that said side branches are easily installed and removed.

  • Patent number: 5065940
    Abstract: A rail fastener includes a rail plate and a rigid stop for rail. The rail plate consists of two parts having a plane surfaces for supporting the rail and extended upward appendages bearing preferably inclined surfaces which cooperate with inclined surfaces of the rail. Each of the parts of the rail plate is placed from opposite lateral side of the rail and they both are tightened with the rail. After they are jointed, the rail fastener becomes as a single whole with rail. One of the parts of the rail plate has a recess one wall of which may be inclined. The rigid stop is mounted in advance into the support structure. When the rail with a rail plate is placed on the support structure, the recess in the rail plate straddles the rigid stop. Then a wedge is mounted into this recess. One of its ends contacts with rigid stop, other which is inclined contacts with inclined wall of the recess in the rail plate. The wedge is bolted to the support structure and pulls up the rail to the rigid stop.

  • Patent number: 4448349
    Abstract: There is disclosed a rail sleeper which when secured to rails affords rapid disengagement when necessary and is comprised of a metal bar of a U-shaped channel section. At two locations along the length of the bar portions of flanges of the sleeper are removed to provide slots disposed at right angles to the longitudinal axis of the bar. Each slot is wider than the base of the rail fitting thereinto with the space between slots dependent upon the gage between parallel rails and with the depth of such slots being varied to suit rail height. One rail flange is secured in place by an overhanging portion of the sleeper flanges. The other rail flange is secured by a generally T-shaped steel plate which is bolted to the bottom of the U-shaped channel section such that the horizontal bar of the T-shaped plate rests across the upright flanges of the sleeper. One edge of the horizontal bar engages the web of the rail and the other edge engages the edge of the slot, thus wedging the rail into secure engagement.
