Abstract
Typically, a tie plate assembly for supporting a rail on a tie includes a tie plate and a spike that is driven through the plate into the tie to secure the tie plate to the point. A sleeve is provided on the plate that is inserted into a tie to prevent the deflection of the spike with respect to the ties wheels of a train pass over the tie.
Claims16
A tie plate assembly comprising:
- a tie plate having a first surface, a second surface, a plurality of holes that are spaced from each other and extend through the tie plate between the first surface and the second surface and a plurality of sleeves that are each delimited by a first end and a second end and fixed at the first end thereof to and extend from the second surface of the tie plate at an outer periphery of each of the holes, the sleeves each being configured to receive a spike and extend into an opening in a railroad tie when the tie plate is mounted on the railroad tie and the sleeves being dimensioned to prevent lateral flexing of the spike after the spike has been inserted through one of the holes and one of the sleeves associated with the one of the holes.
A tie plate, comprising:
- a tie plate body that is configured to support a rail thereon having a top surface, a generally linearly extending bottom surface, a hole extending through the tie plate body between the top surface and the bottom surface, a hollow sleeve delimited by a first end and a second end and fixed at the first end thereof to the bottom surface of the tie plate body at an outer periphery of the hole and the second end spaced away from the tie plate, the hole and the sleeve together defining an orifice that is configured to receive a spike with the sleeve configured to be arranged in an opening in a wood tie, the spike configured to extend through the sleeve and secure the tie plate body on a tie, the sleeve being sized and shaped to prevent deflection of the spike when the spike is inserted through an orifice extending through the sleeve and is imbedded in the wood tie.
A method of attaching a tie plate to a tie, the method comprising the steps of:
- providing a tie plate having a first surface, a generally linear second surface, at least one hole extending through the tie plate between the first surface and the second surface and at least one sleeve that has an orifice that extends therethrough, is delimited at a first end and a second end and fixed at the first end thereof and extends from the second surface of the tie plate at an outer periphery of the hole,
- attaching the tie plate to the tie with the sleeve extending into the tie;
- and
- driving a spike through the hole in the tie plate and the orifice in the sleeve until a portion of the spike is imbedded in the tie and the tie plate is secured to the tie such that the sleeve is positioned to prevent lateral deflection of the spike.
