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.
Claims17
A rail applicator comprising an elongate resilient body defining a passageway consisting of one conduit and an applicator support, the elongate resilient body comprising a top surface defining an exit port, a front surface, a back surface opposite the front surface, the top, front, and back surfaces being impervious to a composition, and a bottom surface opposite the top surface, the elongate resilient body secured to the applicator support, the passageway being impervious to the composition, the applicator support being configured for attaching the rail applicator to a rail so that when the rail applicator is attached to the rail and in fluid communication with a composition source, the front surface of the elongate resilient body is adjacent the rail and the rail applicator applies-the composition to a head portion of the rail, wherein the top surface has a length that is greater than a length between the top surface and the bottom surface.
A rail applicator assembly comprising:
- one or more of a rail applicator and a rail, wherein the rail applicator comprises an elongate resilient body defining a passageway consisting of one conduit and an applicator support, the elongate resilient body comprising a top surface defining an exit port, a front surface, a back surface opposite the front surface, the top, front, and back surfaces being impervious to a composition, and a bottom surface opposite the top surface, the elongate resilient body secured to the applicator support, the passageway being impervious to the composition, the applicator support being configured for attaching the rail applicator to a the rail so that when the rail applicator is attached to the rail and in fluid communication with a composition source, the front surface of the elongate resilient body is adjacent the rail and the rail applicator applies the composition to a head portion of the rail, wherein the top surface has a length that is greater than a length between the top surface and the bottom surface.
