Top of rail applicator
An applicator ( 10 ) for applying a friction modifying material to the top of rails ( 12 ). The wayside applicator includes an applicator bar ( 26 ) that has a dam for holding friction modifying material.
1. A wayside applicator bar for applying a friction modifying material to a head of a rail, comprising:
a body; and
a flow passageway defined in said body for the material to flow through, the flow passageway defining a stationary exit end, said body including a distribution blade and an elastomeric member secured to the distribution blade, an upper end of the distribution blade and the elastomeric member forming a portion of the stationary exit end, the elastomeric member adapted to contain the material for depositing on an outside surface of the head of the rail, wherein said elastomeric member comprises a D-shaped seal.
2. A wayside applicator bar for applying a material to a rail head of a rail as claimed in claim 1 , wherein said rail elastomeric material comprises rubber.
3. A wayside top of rail applicator system, comprising:
a rail that includes a head; and
an applicator for applying friction modifying material to the rail, said applicator comprising a body, a flow passageway defined in said body for the material to flow therethrough, the flow passageway defining a stationary exit end for directing the material to the head, said body including a distribution blade and an elastomeric member secured to the distribution blade, an upper end of the distribution blade and the elastomeric member forming a portion of the stationary exit end, the elastomeric member adapted to contain the material for depositing on an outside surface of the head, wherein said elastomeric member comprises a D-shaped seal.
4. A wayside top of rail applicator system as claimed in claim 3 , wherein said elastomeric member comprises rubber.
