Abstract
A fastening system configured to attach railroad crossties to one or more support structures such as the girder of a bridge. The fastening system includes a plate mounted on a crosstie and a clip attached to the plate that is configured to provide a force between the support structure and the crosstie and secure the crosstie in place.

A railway fastening system for fastening railway crossties to at least one support structure, comprising:
- a plate that is configured to be mounted to a side of the crosstie in a vertical plane with respect to the side of the crosstie and perpendicular to a rail above the crosstie;
- and
- a resilient clip slidably attached to the plate and including a linearly extending section, a curve section extending contiguously from the linearly extending section and a contoured tip extending contiguously from the curved section,
- wherein the contoured tip is configured to contact a surface of the support structure and secure the crosstie to the support structure, and
- wherein the clip can be advanced along the plate and along an underside of the support structure to secure the crosstie to the support structure.
A fastening system securing a railroad crosstie to a support structure, the railroad crosstie having a top surface supporting a rail and a side surface, the support structure having a flange with an upper surface and a bottom surface, the fastening system comprising:
- a plate having at least one flange extendable therefrom with the at least one flange having an opening extending therethrough the plate being fixable to the side surface of the crosstie;
- and
- a clip having a first segment extendable horizontally through the opening in the at least one flange of the plate, a second segment, which is curved, extending contiguous from the first segment and a third segment, which is contoured, extending contiguous from the second segment and engageable with the bottom surface of the flange of the support structure when the crosstie is installed on the upper surface of the support structure with the clip generating a friction force between said crosstie and the support structure.
In a railroad system including rails supported on crossties, a method of anchoring at least one of the crossties to a support structure that includes a flange that has a top surface and a bottom surface, the method comprising:
- providing a fastening system that includes a plate having at least one flange extendable therefrom with an opening extending through the flange and a clip having a first segment that extends linearly, a second segment, which is curved, extending contiguous from the first segment and a third segment, which is contoured, extending contiguous from the second segment;
- attaching the plate to a side surface of the at least one of the crossties;
- placing the at least one of the crossties on the top surface of the support structure;
- inserting the first segment of the clip through the opening in the at least on flange of the fastening system such that the first segment of the clip extends along a side surface of the at least one of the crossties;
- rotating the third segment of the clip from a first position above the top surface of the support structure to a second position below the top surface of the support structure;
- and
- advancing the clip laterally through the opening in the at least one of the flange of the fastening system with the clip end extending along the bottom flange surface to secure the tie to the flange of the support structure.
