Abstract
An applicator for applying a friction modifying material to the surface of a rail is provided. The applicator comprises a resilient body for applying a composition to a surface of a rail. The resilient body comprises an outer impervious surface and defines a sealed passageway that extends through the resilient body for the composition to flow through; and an applicator support, wherein the resilient body is secured to the applicator support. A rail applicator assembly and methods for using the applicator are also provided.
Claims20
A method of applying friction modifying material to a rail, comprising
- engaging a field surface of a head portion of the rail with an applicator, the applicator comprising an elongate resilient polymeric body defining a passageway consisting of one conduit that extends through the elongate resilient polymeric body and comprising an outer impervious surface, the applicator further comprising a rigid applicator support, wherein a bottom surface of the elongate resilient polymeric body is secured directly to an upper surface of the rigid applicator support, the passageway being impervious to the friction modifying material, and wherein a top surface of the elongate resilient polymeric body has a length that is greater than a length between the top surface and the bottom surface of the elongate resilient polymeric body;
- and
- applying the friction modifying material to the field surface of the head portion of the rail by distributing the friction modifying material through the passageway and exiting the passageway via an exit port.
