Wheel And Rail Patents (Class 188/35)
  • Patent number: 7273197
    Abstract: An apparatus for a storage stand for a shopping cart 12 and baby stroller 13 which will keep the shopping cart or baby stroller erect and immobile with a pair of adjustable spring-hinged arms 19 having bungee cords 20 positioned on the outside to keep the cart in the folded position. The apparatus 10 also has a locking pin 40 that can slide vertically to lock the clamps 19 in an upright position. One distal end of the front arm or clamp 19 comprises a loop member 32 where the bungee cord 20 passes through to the second arm or clamp having a ring 30 positioned at its distal end for connecting the bungee cord hooks thereto. The base 14 forming the housing is comprised of slidably engaging members at 22, one forming a shell for the other to selectively slide into and out at the user's discretion. Each of the sliding members has a cavity forming a wheel well 16.

  • Patent number: 7124861
    Abstract: A brake (10) having application for a linear or rotational motion device includes a housing (120) in which a first piston (140), a wedge (142) and a second piston (144) cooperate to engage a friction facing (136) through a plurality of rollers (152, 154, 156, 158). The three part piston assembly (148) allows a braking action and prevents torsional forces that are non-axial to the axis of the first piston (140) and second piston (144). The pistons (140, 144) are biased by compression springs (176) and may be actuated by a fluid.

  • Patent number: 6629709
    Abstract: If the wheel/rail adhesion for a railway vehicle is insufficient then the wheels may slip when braking. If slipping is detected, a control system may reduce the brake pressure to permit a controlled level of slip and so to optimize the braking force for the available adhesion. By determining the pressure supplied to the brake cylinder, a signal may be obtained which indicates the value of the adhesion. Alternatively the adhesion may be monitored by detecting any discrepancy between the braking deceleration demanded by the driver and the observed deceleration. The adhesion signal may activate a warning. It may also be used to adjust the rate at which sand is supplied by a sander to the wheel/rail interface. The rate at which sand is supplied may also be adjusted in accordance with other parameters such as the train speed.

  • Patent number: 6494301
    Abstract: The invention relates to a braking body for a rail car, especially a brake block or disk brake pad, comprising a supporting body with recesses and friction material elements arranged in the recesses. The friction material elements form a friction surface with the supporting body and are mounted with elastic or tilting elements such that the frictional material elements can move in the longitudinal direction of the recesses and adapt themselves to the running surface of a rail wheel.

  • Patent number: 5211266
    Abstract: An improved rail skate intended for mounting on the top of a rail, including an upwardly inclined ramp portion and an entry or toe portion whereby a wheel of an approaching railcar will roll up on top of the entry or toe portion and engage the ramp thereby stopping movement of the wheel relative to the rail skate and thereafter causing the rail skate to slide along the top of the rail until the railcar is ultimately stopped, the rail skate having a shoe element with a substantially V-shaped cross-section including a raised central portion and depending sides.
