Abstract
A rail applicator assembly includes a rail having a head portion, a base portion, and a web portion extending between the head portion and the base portion. The head portion defines an outer surface. An applicator for applying a friction modifying material to the surface of the rail includes a foam body and an applicator support. The foam body is secured to the applicator support and defines a flow passageway that extends through the foam body for friction modifying material to flow through.
Claims23
A rail applicator comprising:
- an elongate foam body configured to apply friction modifying material to a field surface of head portion of a rail, the elongate foam body defining a flow passageway consisting of one conduit that extends through the elongate foam body for the friction modifying material to flow through;
- and
- an applicator support, wherein the elongate foam body is secured to the applicator support.
A rail applicator assembly comprising:
- a rail having a head portion, a base portion, and a web portion extending between the head portion and the base portion, the head portion defining a field surface;
- an applicator for applying a friction modifying material to the field surface of the rail, the applicator comprising a foam body and an applicator support, wherein the foam body is secured to the applicator support and defines a flow passageway consisting of one conduit that extends through the foam body for friction modifying material to flow through, the applicator mounted against the field surface, with a top surface of the foam body inclined downwardly toward the field surface.
A method of applying friction modifying material to a rail, comprising:
- engaging a head portion of a rail with an applicator, the applicator comprising a foam body and an applicator support, the foam body is secured to the applicator support and defines a flow passageway that extends through the foam body;
- and applying friction modifying material to the head portion of the rail by distributing the friction modifying material through the flow passageway and exiting the flow passageway via an exit port.
